Objective To evaluate the beneficial and adverse effects of breviscapine injection in combination with antihypertensive drugs fortreating hypertensive nephropathy in clinical practiceMethodsWe searched PubMed the Cochrane Library Embase CNKI SinoMed VIP and Wanfang Data for relevant literatureThe timeframe of retrieval was set from the founding date of each database toSeptember 28 2018Results Fourteenpaperswere included in this studyThe quality of all the studies includedwas determined to below All studies were conducted with Chinese populations Meta-analysis showed that compared with single-use antihypertensivedrugs using breviscapine injection in combination with antihypertensive drugs to treat hypertensive nephropathy can reduceserum creatinine (Scr) [WMD = ndash3516 95 CI(ndash5001 ndash2031) 119875 le 0001] blood urea nitrogen (BUN) [WMD = ndash200 95CI(ndash307 ndash094) 119875 le 0001] 24-hour urinary total protein (24 h UTP) [WMD = ndash004 95 CI(ndash005 ndash002) 119875 le 0001] and thebeta-2-microglobulin (B2M) [WMD = ndash009 95 CI(ndash011 ndash007) 119875 le 0001] improve creatinine clearance rate (Ccr) [WMD= 784 95 CI(520 1049) 119875 le 0001] and increase the clinical efficacy [RR = 127 95 CI(105 153) 119875 = 0014] but does notlower systolic blood pressure (SBP) [WMD = ndash102 95 CI(ndash288 084) 119875 = 0281] There was no significant difference in adverseevents between experimental groups and control groups Conclusion Breviscapine injection in combination with antihypertensivedrugs can improve clinical efficacy and Ccr and reduce Scr BUN 24 h UTP and B2M in patients with hypertensive nephropathyThe present meta-analysis indicated that breviscapine injection can serve as a renal protective effect to patients with hypertensivenephropathy However the evidence of methodological quality and sample sizes is weak and thus further standardized research isrequired
1 Introduction
Hypertension is a risk factor for stroke coronary arterydisease heart failure peripheral vascular disease and chronickidney disease (CKD) [1 2] Elevated blood pressure (BP)wasthe leading global contributor to premature death in 2015accounting for almost 10 million deaths and over 200 milliondisability-adjusted life years [2] The main factors leadingto the development of hypertensive nephropathy include (1)inappropriately elevated sympathetic nervous activity (SNA)[3] (2) activation of the renin-angiotensin-aldosterone sys-tem (RAAS) [4] (3) increased arterial stiffness [5] (4) genetic
susceptibility [6] (5) impaired salt and water excretion bythe kidney [7] Hypertensive kidney disease is the secondleading cause of end-stage renal disease (ESRD) after dia-betes mellitus [8 9] In Europe according to the EuropeanDialysis and Transplant Association registry hypertensivenephropathy is accounted for 12 of new patients startingrenal replacement therapy However the reported incidencevaries among different countries with France Italy andUnited Kingdom reporting in 25 17 and 61 withboth Japanese and Chinese reporting in 6 and 7 respec-tively [10] Chronic kidney failure is a global disease atthe end of 2016 approximately 3 million patients were

on dialysis The incidence of chronic kidney failure variesbetween regions North America 0638million EuropeMid-dle East and Africa 0711 million Asia-Pacific 1343 millionand Latin America 0288 million [11] The diagnosis ofhypertension-induced renal damage is based on the finding ofreduced renal function andor the detection of albuminuria(ge300mgd or ge300mgg albuminuria to-creatinine ratioin the first morning void) CKD is classified according toestimated glomerular filtration rate (eGFR) calculated bythe 2009 CKD-Epidemiology Collaboration formula [12]Current evidence suggests that in patients with CKD BPshould be lowered to less than 14090mmHg and towards13080mmHgThe combination of renin-angiotensin systemblockers with calcium channel blockers (CCB) or diureticsshould be used to achieve recommended blood pressuretargets in CKD [9 13] A recent meta-analysis has shownthat BP lowering significantly reduced ESRD in patients withCKD but only in patients with albuminuria and had nobeneficial effect on cardiovascular events [14] In a largeretrospective cohort containing 398419 treated hypertensivepatients the nadir systolic blood pressure (SBP) and diastolicblood pressure (DBP) for the lowest risk of ESRD andmortality were 137 and 71mmHg respectively with a clearincrease in mortality risk at SBP less than 120mmHg [15]The evidence with respect to BP targets in patients with CKDis complex Lowering blood pressure may lead to a decreasein eGFR The reduction of albuminuria is also consideredto be a therapeutic target However there are also studiesin which treatment that was less effective at reducing albu-minuria was more effective at reducing cardiovascular events[16]
Breviscapine (Dengzhanhua) injection is extracted fromErigeron breviscapus (Vant) Erigeron breviscapus alsoknown as herba erigerontis or lamp chrysanthemum is atraditional Chinese herb that has been in use for more than600 years found in Yunnan Sichuan Guizhou and othersouthwest provinces of China Breviscapine as a purifiedflavonoid extract from this species was first isolated byZhanget al [17] Breviscapine mainly contains scutellarin (41015840567-tetrahydroxyflavone-7-O-glucuronide) and apigenin-7-O-glucuronide [18] Studies have shown that breviscapine hassignificant effects on vasodilation inhibition of platelet ag-gregation scavenging free radicals also has a protective effecton myocardial and endothelial structures because of its anti-inflammatory effects and improves microcirculationprotection against ischemiareperfusion (IR) anticoag-ulation and antithrombosis reduction of smooth musclecell migration and proliferation anticardiac remodelingantiarrhythmia and reduction of blood lipids [19ndash22]Breviscapine has been demonstrated to possess a number ofpharmacological functions in addition to its hemodynamiceffects it has been reported to serve as an antioxidativestress agent and a protein kinase C (PKC) inhibitor caninhibit the glycogen synthase kinase 3120573 (GSK3120573) signalingpathway to promote neurobehavioral function followingneurotrauma and can improve renal function and reduceurinary microalbuminuria [23ndash26] In the light of thesepharmacological activities an injection preparation ofbreviscapine (a traditional Chinese patent medicine)
has been wildly used in clinical treatment for cerebralinfarction cardiovascular disease diabetic nephropathyrenal impairment of essential hypertension and stroke inChina [18 25 27 28]
However in the past decades although numerous studieshave compared breviscapine injection with antihypertensivedrugs in the treatment of hypertensive nephropathy thecomparability of treatment protocols and evaluation method-ologies among these studies remains to be proven whichgreatly limits their clinical applicability Furthermore thecurrent state of evidence of breviscapine injection for hyper-tensive nephropathy has so far been unknown Therefore weconducted this systematic review to evaluate beneficial andadverse effects of breviscapine injection in the treatment ofhypertensive nephropathy
2 Methods and Analysis
21 Search Strategy We designed our systematic reviewand meta-analysis in accordance with the guidelines ofthe 2009 Preferred Reporting Items for Systematic Reviewsand Meta-analysis (PRISMA) statement Electronic networkdatabases were searched via computer Foreign databasessearched included PubMed Embase and the CochraneLibrary Chinese databases included the China NationalKnowledge Infrastructure (CNKI) China Biology MedicineDisc (Sino Med) the VIP information resource integrationservice platform (VIP) and the Wanfang Data knowledgeservice platform (Wanfang Data) The retrieval schemewas mainly based on a combination of subject words andfree words The searched words were ldquoDengzhanhuardquoldquoDengzhanhua preparationsrdquo ldquoDengzhanhua ZhusheyerdquoldquoZhusheyong Dengzhanhuardquo ldquoGaoxueya Shenbingrdquo ldquoGaox-ueya Shenyanrdquo ldquoGaoxueya Shenshunhairdquo while the searchedEnglish words were ldquoBreviscapinerdquo ldquoBreviscapine InjectionrdquoldquoBVPrdquo ldquoHypertensiveNephropathyrdquo ldquoHypertension RenalrdquoldquoHypertensive Kidney Lesionrdquo ldquoHypertensive Renal Dam-agerdquo and so on (Supplementary Tables S1 and S2 for the searchstrategy) The retrieval language was not limited and thetimeframe of the retrieval was from the founding date of eachdatabase to September 28 2018 There was no language lim-itation Manual searches of relevant literature supplementedthe electronic search
22 Inclusion and Exclusion Criteria
221 Types of Studies Randomized controlled trials (RCTs)that use breviscapine injection in combination with antihy-pertensive drugs to treat hypertensive nephropathy regard-less of blinding were used in this study Language was notrestricted as to minimize publication bias
222 Types of Participants There were no serious organicdiseases or complications in the selected cases The diagno-sis of hypertension-induced renal damage is based on thefinding of reduced renal function andor the detection ofalbuminuria CKD is classified according to eGFR calculatedby the 2009 CKD-Epidemiologyn Collaboration formula[12] Hypertension was defined as SBP ge 140mmHg or
Evidence-Based Complementary and Alternative Medicine 3
DBP ge 90mmHg based on the Chinese Guidelines for thePrevention and Treatment of Hypertension (2010) and the8th session of the Committee Report of the Joint Commis-sionJNC8 secondary hypertension and primary heart liverand brain disorder were excluded We did not limit inclusionbased on age sex case source disease course hypertensiveclassification or antihypertensives
223 Exclusion of Studies Studies were excluded if theywere (1) clinical trials from which no relevant data couldbe extracted (2) studies that were published repeatedly (3)populated with inconsistent baseline information (age sexcase source disease course hypertensive classification orantihypertensive drugs) (4) systematic review importantdata report and case reports no reply from correspondingauthors such that further data could not be obtained and(5) therapeutic measures failing to meet the predeterminedinclusion criteria
224 Intervention Experimental group received breviscap-ine injection combined with antihypertensive drugs [cap-topril amlodipine lisinopril benazepril losartan potas-sium felodipine and nifedipine (medication dose medi-cation time and frequency and treatment course)] Con-trol group received antihypertensive drugs including capto-pril amlodipine lisinopril benazepril losartan potassiumfelodipine nifedipine (medication dose medication timeand frequency and treatment course) Age sex and otherbaseline conditions of research subjects were well matched
225 Types of Outcome Measures Primary outcomes wereserum creatinine (Scr) and 24-hour urinary total pro-tein (24 h UTP) Secondary outcomes included blood ureanitrogen (BUN) creatinine clearance rate (Ccr) beta-2-microglobulin (B2M) systolic blood pressure (SBP) clinicalefficacy and adverse effects
226 Data Extraction Two evaluators independently per-formed a search according to the search strategy and pre-liminary screening was based on independent topics andabstracts of the search results excluding obviously unquali-fied documents A full-text methodology screening was con-ducted on the literature thatmightmeet the inclusion criteriaand the authors were contacted when there was incompleteinformation Then the studies were cross-checked by twoevaluators Any disagreement on the conclusion of twoevaluators was resolved by discussion If such disagreementcould not be resolved through discussion final judgment andarbitration were made by a third party Extracted contentsincluded authorsrsquo names year of publication number ofsamples intervention course of treatment and observedindicators
23 Quality Evaluation The investigators simultaneouslyevaluated the bias risk of the included studies based on theldquorisk of biasrdquo evaluation tool in the Cochrane Handbookfor Systematic Reviews [42] of interventions and relevantassessment guideline regulations This risk-evaluation toolcontains seven items (1) random sequence generation (2)
allocation concealment (3) blinding of the participants andpersonnel (4) blinding of the outcome data (5) incompleteoutcome data (6) selective reporting and (7) other biasand were evaluated as having a ldquohigh risk of biasrdquo ldquolow riskof biasrdquo or ldquounclear risk of biasrdquo according to assessmentcriteria
24 DataAnalysis (1) Stata 140 softwarewas used to performthe statistical analysis for the meta-analysis [43] (2) Selecteffect size if an index of the included documents is a binaryvariable the curative effect analysis statistics can be repre-sented by relative risk (RR) and expressed by its confidenceinterval (CI) mean difference (MD) and 95CI were used torepresent continuous changes (3) Homogeneity test it teststhe variation degree of original research results and clearlyincludes the degree of homogeneity of the experiment (4)Meta-analysis according to the result of the heterogeneitytest P ge 005 and 1198682 lt 50 indicate that the results havegood agreement and that the fixed effect model may be used119875 lt 005 and 1198682 ge 50 suggest that the heterogeneity of theresults cannot be ignored If the included studies still haveclinical significance the random effects model may be used(5) Sensitivity analysis in those meta-analyses of the compre-hensive factors combined with multiple outcomes possibleanomalous studies were ruled out before reevaluation Theresults were compared with those of meta-analysis beforethe exclusion to determine how the excluded studies wouldinfluence the combined effect size and the stability of meta-analysis If there is little difference between the two resultsthen the sensitivity of the results is relatively low and theresults are stable indicating high credibility (6) Subgroupanalysis subgroup analysis was conducted on some indexeswith high heterogeneity For events in which quantitativesynthesis was impossible and events with very low incidencequalitative evaluationmay be based on the description In thisstudy Stata 140 software was used to conduct a sensitivityanalysis and subgroup analysis and to create a sensitivityanalysis chart
25 Publication Bias Publication bias occurs when positivedata in similar research papers with statistical significanceare more likely to be published in journals This situationis hard to control The funnel plot method is often usedto detect publication bias Eggerrsquos test was performed todetect publication bias in the outcome measures If a largepublication bias was found in a particular research index theexact reason was identified

4 Discussion
Thismeta-analysis included 14 studies with 1170 total partici-pants comparing breviscapine injection plus antihypertensivedrugs versus antihypertensive drugs alone for hypertensivenephropathy Meanwhile the results demonstrated that theexpression levels of SCr and BUN were significantly lowerin patients treated with breviscapine injection in comparisonwith control subjects and the improvement of creatinineclearance was higher in patients treated with breviscapinein comparison with control subjects suggesting that thedrug serves as a protective role in the renal system ofpatients with hypertensive nephropathy Microalbuminuriais regarded as the earliest clinical sign of hypertensivenephropathy It is defined as a urinary albumin excretionrate ranging from 30 to 300mgday and the definitivemeasurement is based on a timed urine collection during

a 24-h period The present meta-analysis indicated thatbreviscapine injection can reduce 24-hour urinary proteinand the urinary beta-2-microglobulin a reduction in uri-nary protein may contribute towards the renal protectiveeffect of breviscapine injection in patients with hyperten-sive nephropathy Our analysis revealed that experimentalgroups showed better overall clinical efficacy than controlgroups
Erigeron breviscapus is a kind of traditional Chinesemedicine It was first recorded in the book of ldquoYunnan Mate-ria Medicardquo According to Chinese medicine theory erigeronbreviscapus is cold-natured sweet bitter and pungent intaste with the function of clearing heat relieving toxic-ity eliminating wind and dampness activating blood andremoving stasis expediting channel and activating meridianrelieving inflammation and alleviating pain The monomercomponent of Chinese herbal medicine (CHM) also knownas the natural pure compound drug has recently attractedmuch attention The natural extract artemisinin and itsderivatives are good examples of monomer components ofCHM that can treat diseases through various activities andcan be a good starting point to uncover the mechanism oftraditional Chinese medicine
Hypertensive renal injury is major target-organ damagedue to sustained high BP Long-term hypertension cancause renal sclerosis and gradually progress to chronic renalfailure Positive control of hypertension is the key to pre-venting hypertensive renal damage According to Chinesemedicine theory hypertensive renal injury is strongly relatedto fluid phlegm and dampness retention syndrome andliver-yang hyperactivity syndrome which are caused bydeficiency syndrome Chinese medicines which are usedto treat fluid phlegm and dampness retention syndromedeficiency syndrome and liver-yang hyperactivity syndromerespectively have certain advantages with regard to treatinghypertensive renal injury [45] Clinical research indicatesthat Chinese herbal medicine might control increased SBPinhibit the glomerular and tubular hyperplasia caused byhigh BP and significantly reduce urinary albumin and beta-2-microglobulin by increasing the activity of renal rennin andthe level of Ang II [46 47]

on dialysis The incidence of chronic kidney failure variesbetween regions North America 0638million EuropeMid-dle East and Africa 0711 million Asia-Pacific 1343 millionand Latin America 0288 million [11] The diagnosis ofhypertension-induced renal damage is based on the finding ofreduced renal function andor the detection of albuminuria(ge300mgd or ge300mgg albuminuria to-creatinine ratioin the first morning void) CKD is classified according toestimated glomerular filtration rate (eGFR) calculated bythe 2009 CKD-Epidemiology Collaboration formula [12]Current evidence suggests that in patients with CKD BPshould be lowered to less than 14090mmHg and towards13080mmHgThe combination of renin-angiotensin systemblockers with calcium channel blockers (CCB) or diureticsshould be used to achieve recommended blood pressuretargets in CKD [9 13] A recent meta-analysis has shownthat BP lowering significantly reduced ESRD in patients withCKD but only in patients with albuminuria and had nobeneficial effect on cardiovascular events [14] In a largeretrospective cohort containing 398419 treated hypertensivepatients the nadir systolic blood pressure (SBP) and diastolicblood pressure (DBP) for the lowest risk of ESRD andmortality were 137 and 71mmHg respectively with a clearincrease in mortality risk at SBP less than 120mmHg [15]The evidence with respect to BP targets in patients with CKDis complex Lowering blood pressure may lead to a decreasein eGFR The reduction of albuminuria is also consideredto be a therapeutic target However there are also studiesin which treatment that was less effective at reducing albu-minuria was more effective at reducing cardiovascular events[16]
Breviscapine (Dengzhanhua) injection is extracted fromErigeron breviscapus (Vant) Erigeron breviscapus alsoknown as herba erigerontis or lamp chrysanthemum is atraditional Chinese herb that has been in use for more than600 years found in Yunnan Sichuan Guizhou and othersouthwest provinces of China Breviscapine as a purifiedflavonoid extract from this species was first isolated byZhanget al [17] Breviscapine mainly contains scutellarin (41015840567-tetrahydroxyflavone-7-O-glucuronide) and apigenin-7-O-glucuronide [18] Studies have shown that breviscapine hassignificant effects on vasodilation inhibition of platelet ag-gregation scavenging free radicals also has a protective effecton myocardial and endothelial structures because of its anti-inflammatory effects and improves microcirculationprotection against ischemiareperfusion (IR) anticoag-ulation and antithrombosis reduction of smooth musclecell migration and proliferation anticardiac remodelingantiarrhythmia and reduction of blood lipids [19ndash22]Breviscapine has been demonstrated to possess a number ofpharmacological functions in addition to its hemodynamiceffects it has been reported to serve as an antioxidativestress agent and a protein kinase C (PKC) inhibitor caninhibit the glycogen synthase kinase 3120573 (GSK3120573) signalingpathway to promote neurobehavioral function followingneurotrauma and can improve renal function and reduceurinary microalbuminuria [23ndash26] In the light of thesepharmacological activities an injection preparation ofbreviscapine (a traditional Chinese patent medicine)
has been wildly used in clinical treatment for cerebralinfarction cardiovascular disease diabetic nephropathyrenal impairment of essential hypertension and stroke inChina [18 25 27 28]
However in the past decades although numerous studieshave compared breviscapine injection with antihypertensivedrugs in the treatment of hypertensive nephropathy thecomparability of treatment protocols and evaluation method-ologies among these studies remains to be proven whichgreatly limits their clinical applicability Furthermore thecurrent state of evidence of breviscapine injection for hyper-tensive nephropathy has so far been unknown Therefore weconducted this systematic review to evaluate beneficial andadverse effects of breviscapine injection in the treatment ofhypertensive nephropathy
2 Methods and Analysis
21 Search Strategy We designed our systematic reviewand meta-analysis in accordance with the guidelines ofthe 2009 Preferred Reporting Items for Systematic Reviewsand Meta-analysis (PRISMA) statement Electronic networkdatabases were searched via computer Foreign databasessearched included PubMed Embase and the CochraneLibrary Chinese databases included the China NationalKnowledge Infrastructure (CNKI) China Biology MedicineDisc (Sino Med) the VIP information resource integrationservice platform (VIP) and the Wanfang Data knowledgeservice platform (Wanfang Data) The retrieval schemewas mainly based on a combination of subject words andfree words The searched words were ldquoDengzhanhuardquoldquoDengzhanhua preparationsrdquo ldquoDengzhanhua ZhusheyerdquoldquoZhusheyong Dengzhanhuardquo ldquoGaoxueya Shenbingrdquo ldquoGaox-ueya Shenyanrdquo ldquoGaoxueya Shenshunhairdquo while the searchedEnglish words were ldquoBreviscapinerdquo ldquoBreviscapine InjectionrdquoldquoBVPrdquo ldquoHypertensiveNephropathyrdquo ldquoHypertension RenalrdquoldquoHypertensive Kidney Lesionrdquo ldquoHypertensive Renal Dam-agerdquo and so on (Supplementary Tables S1 and S2 for the searchstrategy) The retrieval language was not limited and thetimeframe of the retrieval was from the founding date of eachdatabase to September 28 2018 There was no language lim-itation Manual searches of relevant literature supplementedthe electronic search
22 Inclusion and Exclusion Criteria
221 Types of Studies Randomized controlled trials (RCTs)that use breviscapine injection in combination with antihy-pertensive drugs to treat hypertensive nephropathy regard-less of blinding were used in this study Language was notrestricted as to minimize publication bias
222 Types of Participants There were no serious organicdiseases or complications in the selected cases The diagno-sis of hypertension-induced renal damage is based on thefinding of reduced renal function andor the detection ofalbuminuria CKD is classified according to eGFR calculatedby the 2009 CKD-Epidemiologyn Collaboration formula[12] Hypertension was defined as SBP ge 140mmHg or
Evidence-Based Complementary and Alternative Medicine 3
DBP ge 90mmHg based on the Chinese Guidelines for thePrevention and Treatment of Hypertension (2010) and the8th session of the Committee Report of the Joint Commis-sionJNC8 secondary hypertension and primary heart liverand brain disorder were excluded We did not limit inclusionbased on age sex case source disease course hypertensiveclassification or antihypertensives
223 Exclusion of Studies Studies were excluded if theywere (1) clinical trials from which no relevant data couldbe extracted (2) studies that were published repeatedly (3)populated with inconsistent baseline information (age sexcase source disease course hypertensive classification orantihypertensive drugs) (4) systematic review importantdata report and case reports no reply from correspondingauthors such that further data could not be obtained and(5) therapeutic measures failing to meet the predeterminedinclusion criteria
224 Intervention Experimental group received breviscap-ine injection combined with antihypertensive drugs [cap-topril amlodipine lisinopril benazepril losartan potas-sium felodipine and nifedipine (medication dose medi-cation time and frequency and treatment course)] Con-trol group received antihypertensive drugs including capto-pril amlodipine lisinopril benazepril losartan potassiumfelodipine nifedipine (medication dose medication timeand frequency and treatment course) Age sex and otherbaseline conditions of research subjects were well matched
225 Types of Outcome Measures Primary outcomes wereserum creatinine (Scr) and 24-hour urinary total pro-tein (24 h UTP) Secondary outcomes included blood ureanitrogen (BUN) creatinine clearance rate (Ccr) beta-2-microglobulin (B2M) systolic blood pressure (SBP) clinicalefficacy and adverse effects
226 Data Extraction Two evaluators independently per-formed a search according to the search strategy and pre-liminary screening was based on independent topics andabstracts of the search results excluding obviously unquali-fied documents A full-text methodology screening was con-ducted on the literature thatmightmeet the inclusion criteriaand the authors were contacted when there was incompleteinformation Then the studies were cross-checked by twoevaluators Any disagreement on the conclusion of twoevaluators was resolved by discussion If such disagreementcould not be resolved through discussion final judgment andarbitration were made by a third party Extracted contentsincluded authorsrsquo names year of publication number ofsamples intervention course of treatment and observedindicators
23 Quality Evaluation The investigators simultaneouslyevaluated the bias risk of the included studies based on theldquorisk of biasrdquo evaluation tool in the Cochrane Handbookfor Systematic Reviews [42] of interventions and relevantassessment guideline regulations This risk-evaluation toolcontains seven items (1) random sequence generation (2)
allocation concealment (3) blinding of the participants andpersonnel (4) blinding of the outcome data (5) incompleteoutcome data (6) selective reporting and (7) other biasand were evaluated as having a ldquohigh risk of biasrdquo ldquolow riskof biasrdquo or ldquounclear risk of biasrdquo according to assessmentcriteria
24 DataAnalysis (1) Stata 140 softwarewas used to performthe statistical analysis for the meta-analysis [43] (2) Selecteffect size if an index of the included documents is a binaryvariable the curative effect analysis statistics can be repre-sented by relative risk (RR) and expressed by its confidenceinterval (CI) mean difference (MD) and 95CI were used torepresent continuous changes (3) Homogeneity test it teststhe variation degree of original research results and clearlyincludes the degree of homogeneity of the experiment (4)Meta-analysis according to the result of the heterogeneitytest P ge 005 and 1198682 lt 50 indicate that the results havegood agreement and that the fixed effect model may be used119875 lt 005 and 1198682 ge 50 suggest that the heterogeneity of theresults cannot be ignored If the included studies still haveclinical significance the random effects model may be used(5) Sensitivity analysis in those meta-analyses of the compre-hensive factors combined with multiple outcomes possibleanomalous studies were ruled out before reevaluation Theresults were compared with those of meta-analysis beforethe exclusion to determine how the excluded studies wouldinfluence the combined effect size and the stability of meta-analysis If there is little difference between the two resultsthen the sensitivity of the results is relatively low and theresults are stable indicating high credibility (6) Subgroupanalysis subgroup analysis was conducted on some indexeswith high heterogeneity For events in which quantitativesynthesis was impossible and events with very low incidencequalitative evaluationmay be based on the description In thisstudy Stata 140 software was used to conduct a sensitivityanalysis and subgroup analysis and to create a sensitivityanalysis chart
25 Publication Bias Publication bias occurs when positivedata in similar research papers with statistical significanceare more likely to be published in journals This situationis hard to control The funnel plot method is often usedto detect publication bias Eggerrsquos test was performed todetect publication bias in the outcome measures If a largepublication bias was found in a particular research index theexact reason was identified

3410 Adverse Effects Nine of the included trials [29ndash36 38]described adverse effects in detail while the others did notmention adverse eventsOnly one showedmild facial flushingduring intravenous dripping of breviscapine [30] and afterthe speed of transfusion was slowed down the symptom gotremitted Two cases [38] showed redness of limb skin in theexperimental group There were two cases [31 32] of headinflation during the use of antihypertensive drugsTherewerethree cases [33 34] of head swelling and dizziness duringinfusion during the use of breviscapine injection Twenty-onecases showed dry cough due to the use of ACEI in six trials[29 31ndash33 35 36] None of the adverse events were seriousThese symptoms are self-limited and did not affect treatment
4 Discussion
Thismeta-analysis included 14 studies with 1170 total partici-pants comparing breviscapine injection plus antihypertensivedrugs versus antihypertensive drugs alone for hypertensivenephropathy Meanwhile the results demonstrated that theexpression levels of SCr and BUN were significantly lowerin patients treated with breviscapine injection in comparisonwith control subjects and the improvement of creatinineclearance was higher in patients treated with breviscapinein comparison with control subjects suggesting that thedrug serves as a protective role in the renal system ofpatients with hypertensive nephropathy Microalbuminuriais regarded as the earliest clinical sign of hypertensivenephropathy It is defined as a urinary albumin excretionrate ranging from 30 to 300mgday and the definitivemeasurement is based on a timed urine collection during

a 24-h period The present meta-analysis indicated thatbreviscapine injection can reduce 24-hour urinary proteinand the urinary beta-2-microglobulin a reduction in uri-nary protein may contribute towards the renal protectiveeffect of breviscapine injection in patients with hyperten-sive nephropathy Our analysis revealed that experimentalgroups showed better overall clinical efficacy than controlgroups
Erigeron breviscapus is a kind of traditional Chinesemedicine It was first recorded in the book of ldquoYunnan Mate-ria Medicardquo According to Chinese medicine theory erigeronbreviscapus is cold-natured sweet bitter and pungent intaste with the function of clearing heat relieving toxic-ity eliminating wind and dampness activating blood andremoving stasis expediting channel and activating meridianrelieving inflammation and alleviating pain The monomercomponent of Chinese herbal medicine (CHM) also knownas the natural pure compound drug has recently attractedmuch attention The natural extract artemisinin and itsderivatives are good examples of monomer components ofCHM that can treat diseases through various activities andcan be a good starting point to uncover the mechanism oftraditional Chinese medicine
Hypertensive renal injury is major target-organ damagedue to sustained high BP Long-term hypertension cancause renal sclerosis and gradually progress to chronic renalfailure Positive control of hypertension is the key to pre-venting hypertensive renal damage According to Chinesemedicine theory hypertensive renal injury is strongly relatedto fluid phlegm and dampness retention syndrome andliver-yang hyperactivity syndrome which are caused bydeficiency syndrome Chinese medicines which are usedto treat fluid phlegm and dampness retention syndromedeficiency syndrome and liver-yang hyperactivity syndromerespectively have certain advantages with regard to treatinghypertensive renal injury [45] Clinical research indicatesthat Chinese herbal medicine might control increased SBPinhibit the glomerular and tubular hyperplasia caused byhigh BP and significantly reduce urinary albumin and beta-2-microglobulin by increasing the activity of renal rennin andthe level of Ang II [46 47]

223 Exclusion of Studies Studies were excluded if theywere (1) clinical trials from which no relevant data couldbe extracted (2) studies that were published repeatedly (3)populated with inconsistent baseline information (age sexcase source disease course hypertensive classification orantihypertensive drugs) (4) systematic review importantdata report and case reports no reply from correspondingauthors such that further data could not be obtained and(5) therapeutic measures failing to meet the predeterminedinclusion criteria
224 Intervention Experimental group received breviscap-ine injection combined with antihypertensive drugs [cap-topril amlodipine lisinopril benazepril losartan potas-sium felodipine and nifedipine (medication dose medi-cation time and frequency and treatment course)] Con-trol group received antihypertensive drugs including capto-pril amlodipine lisinopril benazepril losartan potassiumfelodipine nifedipine (medication dose medication timeand frequency and treatment course) Age sex and otherbaseline conditions of research subjects were well matched
225 Types of Outcome Measures Primary outcomes wereserum creatinine (Scr) and 24-hour urinary total pro-tein (24 h UTP) Secondary outcomes included blood ureanitrogen (BUN) creatinine clearance rate (Ccr) beta-2-microglobulin (B2M) systolic blood pressure (SBP) clinicalefficacy and adverse effects
226 Data Extraction Two evaluators independently per-formed a search according to the search strategy and pre-liminary screening was based on independent topics andabstracts of the search results excluding obviously unquali-fied documents A full-text methodology screening was con-ducted on the literature thatmightmeet the inclusion criteriaand the authors were contacted when there was incompleteinformation Then the studies were cross-checked by twoevaluators Any disagreement on the conclusion of twoevaluators was resolved by discussion If such disagreementcould not be resolved through discussion final judgment andarbitration were made by a third party Extracted contentsincluded authorsrsquo names year of publication number ofsamples intervention course of treatment and observedindicators
23 Quality Evaluation The investigators simultaneouslyevaluated the bias risk of the included studies based on theldquorisk of biasrdquo evaluation tool in the Cochrane Handbookfor Systematic Reviews [42] of interventions and relevantassessment guideline regulations This risk-evaluation toolcontains seven items (1) random sequence generation (2)
allocation concealment (3) blinding of the participants andpersonnel (4) blinding of the outcome data (5) incompleteoutcome data (6) selective reporting and (7) other biasand were evaluated as having a ldquohigh risk of biasrdquo ldquolow riskof biasrdquo or ldquounclear risk of biasrdquo according to assessmentcriteria
24 DataAnalysis (1) Stata 140 softwarewas used to performthe statistical analysis for the meta-analysis [43] (2) Selecteffect size if an index of the included documents is a binaryvariable the curative effect analysis statistics can be repre-sented by relative risk (RR) and expressed by its confidenceinterval (CI) mean difference (MD) and 95CI were used torepresent continuous changes (3) Homogeneity test it teststhe variation degree of original research results and clearlyincludes the degree of homogeneity of the experiment (4)Meta-analysis according to the result of the heterogeneitytest P ge 005 and 1198682 lt 50 indicate that the results havegood agreement and that the fixed effect model may be used119875 lt 005 and 1198682 ge 50 suggest that the heterogeneity of theresults cannot be ignored If the included studies still haveclinical significance the random effects model may be used(5) Sensitivity analysis in those meta-analyses of the compre-hensive factors combined with multiple outcomes possibleanomalous studies were ruled out before reevaluation Theresults were compared with those of meta-analysis beforethe exclusion to determine how the excluded studies wouldinfluence the combined effect size and the stability of meta-analysis If there is little difference between the two resultsthen the sensitivity of the results is relatively low and theresults are stable indicating high credibility (6) Subgroupanalysis subgroup analysis was conducted on some indexeswith high heterogeneity For events in which quantitativesynthesis was impossible and events with very low incidencequalitative evaluationmay be based on the description In thisstudy Stata 140 software was used to conduct a sensitivityanalysis and subgroup analysis and to create a sensitivityanalysis chart
25 Publication Bias Publication bias occurs when positivedata in similar research papers with statistical significanceare more likely to be published in journals This situationis hard to control The funnel plot method is often usedto detect publication bias Eggerrsquos test was performed todetect publication bias in the outcome measures If a largepublication bias was found in a particular research index theexact reason was identified

4 Discussion
Thismeta-analysis included 14 studies with 1170 total partici-pants comparing breviscapine injection plus antihypertensivedrugs versus antihypertensive drugs alone for hypertensivenephropathy Meanwhile the results demonstrated that theexpression levels of SCr and BUN were significantly lowerin patients treated with breviscapine injection in comparisonwith control subjects and the improvement of creatinineclearance was higher in patients treated with breviscapinein comparison with control subjects suggesting that thedrug serves as a protective role in the renal system ofpatients with hypertensive nephropathy Microalbuminuriais regarded as the earliest clinical sign of hypertensivenephropathy It is defined as a urinary albumin excretionrate ranging from 30 to 300mgday and the definitivemeasurement is based on a timed urine collection during

a 24-h period The present meta-analysis indicated thatbreviscapine injection can reduce 24-hour urinary proteinand the urinary beta-2-microglobulin a reduction in uri-nary protein may contribute towards the renal protectiveeffect of breviscapine injection in patients with hyperten-sive nephropathy Our analysis revealed that experimentalgroups showed better overall clinical efficacy than controlgroups
Erigeron breviscapus is a kind of traditional Chinesemedicine It was first recorded in the book of ldquoYunnan Mate-ria Medicardquo According to Chinese medicine theory erigeronbreviscapus is cold-natured sweet bitter and pungent intaste with the function of clearing heat relieving toxic-ity eliminating wind and dampness activating blood andremoving stasis expediting channel and activating meridianrelieving inflammation and alleviating pain The monomercomponent of Chinese herbal medicine (CHM) also knownas the natural pure compound drug has recently attractedmuch attention The natural extract artemisinin and itsderivatives are good examples of monomer components ofCHM that can treat diseases through various activities andcan be a good starting point to uncover the mechanism oftraditional Chinese medicine
Hypertensive renal injury is major target-organ damagedue to sustained high BP Long-term hypertension cancause renal sclerosis and gradually progress to chronic renalfailure Positive control of hypertension is the key to pre-venting hypertensive renal damage According to Chinesemedicine theory hypertensive renal injury is strongly relatedto fluid phlegm and dampness retention syndrome andliver-yang hyperactivity syndrome which are caused bydeficiency syndrome Chinese medicines which are usedto treat fluid phlegm and dampness retention syndromedeficiency syndrome and liver-yang hyperactivity syndromerespectively have certain advantages with regard to treatinghypertensive renal injury [45] Clinical research indicatesthat Chinese herbal medicine might control increased SBPinhibit the glomerular and tubular hyperplasia caused byhigh BP and significantly reduce urinary albumin and beta-2-microglobulin by increasing the activity of renal rennin andthe level of Ang II [46 47]
5 Limitations
Several limiting factors in this study should be consideredFirst the quality of the included randomized controlled trials

controlled trials are needed to provide accurate data tofurther validate the effectiveness and safety of breviscapineinjection
6 Conclusions
Evidence from this systematic review shows that breviscap-ine injection in combination with antihypertensive drugscan improve clinical efficacy and creatinine clearance rate

4 Discussion
Thismeta-analysis included 14 studies with 1170 total partici-pants comparing breviscapine injection plus antihypertensivedrugs versus antihypertensive drugs alone for hypertensivenephropathy Meanwhile the results demonstrated that theexpression levels of SCr and BUN were significantly lowerin patients treated with breviscapine injection in comparisonwith control subjects and the improvement of creatinineclearance was higher in patients treated with breviscapinein comparison with control subjects suggesting that thedrug serves as a protective role in the renal system ofpatients with hypertensive nephropathy Microalbuminuriais regarded as the earliest clinical sign of hypertensivenephropathy It is defined as a urinary albumin excretionrate ranging from 30 to 300mgday and the definitivemeasurement is based on a timed urine collection during

a 24-h period The present meta-analysis indicated thatbreviscapine injection can reduce 24-hour urinary proteinand the urinary beta-2-microglobulin a reduction in uri-nary protein may contribute towards the renal protectiveeffect of breviscapine injection in patients with hyperten-sive nephropathy Our analysis revealed that experimentalgroups showed better overall clinical efficacy than controlgroups
Erigeron breviscapus is a kind of traditional Chinesemedicine It was first recorded in the book of ldquoYunnan Mate-ria Medicardquo According to Chinese medicine theory erigeronbreviscapus is cold-natured sweet bitter and pungent intaste with the function of clearing heat relieving toxic-ity eliminating wind and dampness activating blood andremoving stasis expediting channel and activating meridianrelieving inflammation and alleviating pain The monomercomponent of Chinese herbal medicine (CHM) also knownas the natural pure compound drug has recently attractedmuch attention The natural extract artemisinin and itsderivatives are good examples of monomer components ofCHM that can treat diseases through various activities andcan be a good starting point to uncover the mechanism oftraditional Chinese medicine
Hypertensive renal injury is major target-organ damagedue to sustained high BP Long-term hypertension cancause renal sclerosis and gradually progress to chronic renalfailure Positive control of hypertension is the key to pre-venting hypertensive renal damage According to Chinesemedicine theory hypertensive renal injury is strongly relatedto fluid phlegm and dampness retention syndrome andliver-yang hyperactivity syndrome which are caused bydeficiency syndrome Chinese medicines which are usedto treat fluid phlegm and dampness retention syndromedeficiency syndrome and liver-yang hyperactivity syndromerespectively have certain advantages with regard to treatinghypertensive renal injury [45] Clinical research indicatesthat Chinese herbal medicine might control increased SBPinhibit the glomerular and tubular hyperplasia caused byhigh BP and significantly reduce urinary albumin and beta-2-microglobulin by increasing the activity of renal rennin andthe level of Ang II [46 47]

Overall our results suggest that breviscapine injection iseffective and safe for the treatment of hypertensive nephropa-thy and this work has reference value for clinicians Morelarge-scale multicenter rigorously designed randomized
controlled trials are needed to provide accurate data tofurther validate the effectiveness and safety of breviscapineinjection

4 Discussion
Thismeta-analysis included 14 studies with 1170 total partici-pants comparing breviscapine injection plus antihypertensivedrugs versus antihypertensive drugs alone for hypertensivenephropathy Meanwhile the results demonstrated that theexpression levels of SCr and BUN were significantly lowerin patients treated with breviscapine injection in comparisonwith control subjects and the improvement of creatinineclearance was higher in patients treated with breviscapinein comparison with control subjects suggesting that thedrug serves as a protective role in the renal system ofpatients with hypertensive nephropathy Microalbuminuriais regarded as the earliest clinical sign of hypertensivenephropathy It is defined as a urinary albumin excretionrate ranging from 30 to 300mgday and the definitivemeasurement is based on a timed urine collection during

Figure 7 Meta-analysis results of breviscapine injection plus antihypertensive drugs versus antihypertensive drugs alone in terms of the 24 hUTP for hypertensive nephropathy
a 24-h period The present meta-analysis indicated thatbreviscapine injection can reduce 24-hour urinary proteinand the urinary beta-2-microglobulin a reduction in uri-nary protein may contribute towards the renal protectiveeffect of breviscapine injection in patients with hyperten-sive nephropathy Our analysis revealed that experimentalgroups showed better overall clinical efficacy than controlgroups
Erigeron breviscapus is a kind of traditional Chinesemedicine It was first recorded in the book of ldquoYunnan Mate-ria Medicardquo According to Chinese medicine theory erigeronbreviscapus is cold-natured sweet bitter and pungent intaste with the function of clearing heat relieving toxic-ity eliminating wind and dampness activating blood andremoving stasis expediting channel and activating meridianrelieving inflammation and alleviating pain The monomercomponent of Chinese herbal medicine (CHM) also knownas the natural pure compound drug has recently attractedmuch attention The natural extract artemisinin and itsderivatives are good examples of monomer components ofCHM that can treat diseases through various activities andcan be a good starting point to uncover the mechanism oftraditional Chinese medicine
Hypertensive renal injury is major target-organ damagedue to sustained high BP Long-term hypertension cancause renal sclerosis and gradually progress to chronic renalfailure Positive control of hypertension is the key to pre-venting hypertensive renal damage According to Chinesemedicine theory hypertensive renal injury is strongly relatedto fluid phlegm and dampness retention syndrome andliver-yang hyperactivity syndrome which are caused bydeficiency syndrome Chinese medicines which are usedto treat fluid phlegm and dampness retention syndromedeficiency syndrome and liver-yang hyperactivity syndromerespectively have certain advantages with regard to treatinghypertensive renal injury [45] Clinical research indicatesthat Chinese herbal medicine might control increased SBPinhibit the glomerular and tubular hyperplasia caused byhigh BP and significantly reduce urinary albumin and beta-2-microglobulin by increasing the activity of renal rennin andthe level of Ang II [46 47]
5 Limitations
Several limiting factors in this study should be consideredFirst the quality of the included randomized controlled trials

Overall our results suggest that breviscapine injection iseffective and safe for the treatment of hypertensive nephropa-thy and this work has reference value for clinicians Morelarge-scale multicenter rigorously designed randomized
controlled trials are needed to provide accurate data tofurther validate the effectiveness and safety of breviscapineinjection
6 Conclusions
Evidence from this systematic review shows that breviscap-ine injection in combination with antihypertensive drugscan improve clinical efficacy and creatinine clearance rate

119875 le 0001) (Figure 4) we employed a random effectsmodel A funnel plot analysis of the 12 trials suggestedpossible publication bias and inclusion of low quality studiesas significant asymmetry is shown in Figure 5 We appliedEggerrsquos test to evaluate publication bias A p (P = 0634)value more than 005 was considered no publication bias(Supplementary Figure S1) The meta-analysis revealed thatthe experimental group performed better than the controlgroup in reducing Scr [WMD = ndash3516 95 CI(ndash5001ndash2031) 119875 le 0001] (Supplementary Figure S2)
342 Sensitivity Analysis We conducted a sensitivity analy-sis for Scr (Supplementary Figure S3) By seriatim excludingone trial each time and reperforming meta-analysis of theremaining trials we could observe whether the outcomeshave dramatically changed Sensitivity analysis indicated thatthe outcomes of Scr were very similar which had relativelygood stability
343 Subgroup Analysis Because of variability in evaluat-ing point of the serum creatinine we conducted subgroupanalysis among studies using different doses of breviscapineinjection (30ml 20ml 12ml 10ml and 5ml) Comparedwith the control groups the results of subgroup analysisshowed that there was no significant correlation between thedecrease of serum creatinine and the dose of breviscapineinjection (Figure 6)
344 24-Hour Urinary Total Protein (24h UTP gd) Twelvestudies [29ndash36 38ndash40 44] reported on the use of brevis-capine injection plus antihypertensive drugs in terms ofthe 24 h UTP for hypertensive nephropathy After the testfor heterogeneity (1198682 = 937 P le 0001) (Figure 7) weemployed a random effects modelWe conducted a sensitivity
analysis and applied Eggerrsquos test (P = 0586) to evaluatepublication bias for 24 h UTP (Supplementary Figures S4and S5) The meta-analysis revealed that the experimentalgroup performed better than the control group in reducing24 h UTP [WMD = ndash004 95 CI(ndash005 ndash002) 119875 le 0001](Figure S6)
345 Blood Urea Nitrogen (BUN mmolL) Ten studies [30ndash33 35ndash40] reported on the use of breviscapine injectionplus antihypertensive drugs in the treatment of BUN forhypertensive nephropathy After the test for heterogeneity(1198682 = 923 119875 le 0001) (Figure 8) we employed arandom effects model We conducted a sensitivity analysisand applied Eggerrsquos test (P = 0015) to evaluate publicationbias for BUN (Supplementary Figures S7 and S8) The meta-analysis revealed that the experimental group performedbetter than the control group in reducing BUN [WMD =ndash200 95 CI(ndash307 ndash094) 119875 le 0001] (SupplementaryFigure S9)
346 Creatinine Clearance Rate (Ccr mlmin) Three studies[33 34 44] reported on the use of breviscapine injectionplus antihypertensive drugs in the treatment of Ccr forhypertensive nephropathy After the test for heterogeneity(1198682 = 00 119875 = 0903) (Figure 9) thus the fixed-effects model was used for data analysis The meta-analysisrevealed that the experimental group performed better thanthe control group in improving creatinine clearance rate[WMD = 784 95 CI(520 1049) 119875 le 0001] (Figure S10)

348 Systolic Blood Pressure (SBP mmHg) Nine studies[29 34ndash38 40 41 44] reported on the use of breviscapineinjection plus antihypertensive drugs in the treatment of SBPfor hypertensive nephropathy After the test for heterogeneity(1198682 = 79 119875 le 0001) (Figure 11) we employed arandomeffectsmodelMeta-analysis showed anonsignificanttrend for reduction in systolic blood pressure between theexperimental group and the control group [WMD = ndash10295 CI(ndash288 084) 119875 = 0281] (Figure S12)
349 Comparison of Clinical Efficacy A total of 7 studies[31 33 35 36 38ndash40] reported the results of the total effectiverate involving 657 patients (330 in the experimental groupand 327 in the control group) After the test for heterogeneity(1198682 = 852 119875 le 0001) (Figure 12) we employed arandom effects model We conducted a sensitivity analysisand applied Eggerrsquos test (119875 = 0181) to evaluate publicationbias for effective rate (Supplementary Figures S13 and S14)Meta-analysis indicated that the total clinical effective rateof breviscapine injection plus antihypertensive drugs versusantihypertensive drugs alone in treating for hypertensivenephropathy was higher than that in the control group whichshowed a statistically significant difference [RR = 127 95CI(105 153)119875 = 0014] (Figure S15) All included trials werepublished in Chinese academic journals Since trials withnegative or neutral results are less likely to be published

Thismeta-analysis included 14 studies with 1170 total partici-pants comparing breviscapine injection plus antihypertensivedrugs versus antihypertensive drugs alone for hypertensivenephropathy Meanwhile the results demonstrated that theexpression levels of SCr and BUN were significantly lowerin patients treated with breviscapine injection in comparisonwith control subjects and the improvement of creatinineclearance was higher in patients treated with breviscapinein comparison with control subjects suggesting that thedrug serves as a protective role in the renal system ofpatients with hypertensive nephropathy Microalbuminuriais regarded as the earliest clinical sign of hypertensivenephropathy It is defined as a urinary albumin excretionrate ranging from 30 to 300mgday and the definitivemeasurement is based on a timed urine collection during

a 24-h period The present meta-analysis indicated thatbreviscapine injection can reduce 24-hour urinary proteinand the urinary beta-2-microglobulin a reduction in uri-nary protein may contribute towards the renal protectiveeffect of breviscapine injection in patients with hyperten-sive nephropathy Our analysis revealed that experimentalgroups showed better overall clinical efficacy than controlgroups
Erigeron breviscapus is a kind of traditional Chinesemedicine It was first recorded in the book of ldquoYunnan Mate-ria Medicardquo According to Chinese medicine theory erigeronbreviscapus is cold-natured sweet bitter and pungent intaste with the function of clearing heat relieving toxic-ity eliminating wind and dampness activating blood andremoving stasis expediting channel and activating meridianrelieving inflammation and alleviating pain The monomercomponent of Chinese herbal medicine (CHM) also knownas the natural pure compound drug has recently attractedmuch attention The natural extract artemisinin and itsderivatives are good examples of monomer components ofCHM that can treat diseases through various activities andcan be a good starting point to uncover the mechanism oftraditional Chinese medicine
Hypertensive renal injury is major target-organ damagedue to sustained high BP Long-term hypertension cancause renal sclerosis and gradually progress to chronic renalfailure Positive control of hypertension is the key to pre-venting hypertensive renal damage According to Chinesemedicine theory hypertensive renal injury is strongly relatedto fluid phlegm and dampness retention syndrome andliver-yang hyperactivity syndrome which are caused bydeficiency syndrome Chinese medicines which are usedto treat fluid phlegm and dampness retention syndromedeficiency syndrome and liver-yang hyperactivity syndromerespectively have certain advantages with regard to treatinghypertensive renal injury [45] Clinical research indicatesthat Chinese herbal medicine might control increased SBPinhibit the glomerular and tubular hyperplasia caused byhigh BP and significantly reduce urinary albumin and beta-2-microglobulin by increasing the activity of renal rennin andthe level of Ang II [46 47]
5 Limitations
Several limiting factors in this study should be consideredFirst the quality of the included randomized controlled trials

Overall our results suggest that breviscapine injection iseffective and safe for the treatment of hypertensive nephropa-thy and this work has reference value for clinicians Morelarge-scale multicenter rigorously designed randomized
controlled trials are needed to provide accurate data tofurther validate the effectiveness and safety of breviscapineinjection
6 Conclusions
Evidence from this systematic review shows that breviscap-ine injection in combination with antihypertensive drugscan improve clinical efficacy and creatinine clearance rate

4 Discussion
Thismeta-analysis included 14 studies with 1170 total partici-pants comparing breviscapine injection plus antihypertensivedrugs versus antihypertensive drugs alone for hypertensivenephropathy Meanwhile the results demonstrated that theexpression levels of SCr and BUN were significantly lowerin patients treated with breviscapine injection in comparisonwith control subjects and the improvement of creatinineclearance was higher in patients treated with breviscapinein comparison with control subjects suggesting that thedrug serves as a protective role in the renal system ofpatients with hypertensive nephropathy Microalbuminuriais regarded as the earliest clinical sign of hypertensivenephropathy It is defined as a urinary albumin excretionrate ranging from 30 to 300mgday and the definitivemeasurement is based on a timed urine collection during

a 24-h period The present meta-analysis indicated thatbreviscapine injection can reduce 24-hour urinary proteinand the urinary beta-2-microglobulin a reduction in uri-nary protein may contribute towards the renal protectiveeffect of breviscapine injection in patients with hyperten-sive nephropathy Our analysis revealed that experimentalgroups showed better overall clinical efficacy than controlgroups
Erigeron breviscapus is a kind of traditional Chinesemedicine It was first recorded in the book of ldquoYunnan Mate-ria Medicardquo According to Chinese medicine theory erigeronbreviscapus is cold-natured sweet bitter and pungent intaste with the function of clearing heat relieving toxic-ity eliminating wind and dampness activating blood andremoving stasis expediting channel and activating meridianrelieving inflammation and alleviating pain The monomercomponent of Chinese herbal medicine (CHM) also knownas the natural pure compound drug has recently attractedmuch attention The natural extract artemisinin and itsderivatives are good examples of monomer components ofCHM that can treat diseases through various activities andcan be a good starting point to uncover the mechanism oftraditional Chinese medicine
Hypertensive renal injury is major target-organ damagedue to sustained high BP Long-term hypertension cancause renal sclerosis and gradually progress to chronic renalfailure Positive control of hypertension is the key to pre-venting hypertensive renal damage According to Chinesemedicine theory hypertensive renal injury is strongly relatedto fluid phlegm and dampness retention syndrome andliver-yang hyperactivity syndrome which are caused bydeficiency syndrome Chinese medicines which are usedto treat fluid phlegm and dampness retention syndromedeficiency syndrome and liver-yang hyperactivity syndromerespectively have certain advantages with regard to treatinghypertensive renal injury [45] Clinical research indicatesthat Chinese herbal medicine might control increased SBPinhibit the glomerular and tubular hyperplasia caused byhigh BP and significantly reduce urinary albumin and beta-2-microglobulin by increasing the activity of renal rennin andthe level of Ang II [46 47]
5 Limitations
Several limiting factors in this study should be consideredFirst the quality of the included randomized controlled trials

Overall our results suggest that breviscapine injection iseffective and safe for the treatment of hypertensive nephropa-thy and this work has reference value for clinicians Morelarge-scale multicenter rigorously designed randomized
controlled trials are needed to provide accurate data tofurther validate the effectiveness and safety of breviscapineinjection
6 Conclusions
Evidence from this systematic review shows that breviscap-ine injection in combination with antihypertensive drugscan improve clinical efficacy and creatinine clearance rate

4 Discussion
Thismeta-analysis included 14 studies with 1170 total partici-pants comparing breviscapine injection plus antihypertensivedrugs versus antihypertensive drugs alone for hypertensivenephropathy Meanwhile the results demonstrated that theexpression levels of SCr and BUN were significantly lowerin patients treated with breviscapine injection in comparisonwith control subjects and the improvement of creatinineclearance was higher in patients treated with breviscapinein comparison with control subjects suggesting that thedrug serves as a protective role in the renal system ofpatients with hypertensive nephropathy Microalbuminuriais regarded as the earliest clinical sign of hypertensivenephropathy It is defined as a urinary albumin excretionrate ranging from 30 to 300mgday and the definitivemeasurement is based on a timed urine collection during

a 24-h period The present meta-analysis indicated thatbreviscapine injection can reduce 24-hour urinary proteinand the urinary beta-2-microglobulin a reduction in uri-nary protein may contribute towards the renal protectiveeffect of breviscapine injection in patients with hyperten-sive nephropathy Our analysis revealed that experimentalgroups showed better overall clinical efficacy than controlgroups
Erigeron breviscapus is a kind of traditional Chinesemedicine It was first recorded in the book of ldquoYunnan Mate-ria Medicardquo According to Chinese medicine theory erigeronbreviscapus is cold-natured sweet bitter and pungent intaste with the function of clearing heat relieving toxic-ity eliminating wind and dampness activating blood andremoving stasis expediting channel and activating meridianrelieving inflammation and alleviating pain The monomercomponent of Chinese herbal medicine (CHM) also knownas the natural pure compound drug has recently attractedmuch attention The natural extract artemisinin and itsderivatives are good examples of monomer components ofCHM that can treat diseases through various activities andcan be a good starting point to uncover the mechanism oftraditional Chinese medicine
Hypertensive renal injury is major target-organ damagedue to sustained high BP Long-term hypertension cancause renal sclerosis and gradually progress to chronic renalfailure Positive control of hypertension is the key to pre-venting hypertensive renal damage According to Chinesemedicine theory hypertensive renal injury is strongly relatedto fluid phlegm and dampness retention syndrome andliver-yang hyperactivity syndrome which are caused bydeficiency syndrome Chinese medicines which are usedto treat fluid phlegm and dampness retention syndromedeficiency syndrome and liver-yang hyperactivity syndromerespectively have certain advantages with regard to treatinghypertensive renal injury [45] Clinical research indicatesthat Chinese herbal medicine might control increased SBPinhibit the glomerular and tubular hyperplasia caused byhigh BP and significantly reduce urinary albumin and beta-2-microglobulin by increasing the activity of renal rennin andthe level of Ang II [46 47]

Overall our results suggest that breviscapine injection iseffective and safe for the treatment of hypertensive nephropa-thy and this work has reference value for clinicians Morelarge-scale multicenter rigorously designed randomized
controlled trials are needed to provide accurate data tofurther validate the effectiveness and safety of breviscapineinjection
6 Conclusions
Evidence from this systematic review shows that breviscap-ine injection in combination with antihypertensive drugscan improve clinical efficacy and creatinine clearance rate

3410 Adverse Effects Nine of the included trials [29ndash36 38]described adverse effects in detail while the others did notmention adverse eventsOnly one showedmild facial flushingduring intravenous dripping of breviscapine [30] and afterthe speed of transfusion was slowed down the symptom gotremitted Two cases [38] showed redness of limb skin in theexperimental group There were two cases [31 32] of headinflation during the use of antihypertensive drugsTherewerethree cases [33 34] of head swelling and dizziness duringinfusion during the use of breviscapine injection Twenty-onecases showed dry cough due to the use of ACEI in six trials[29 31ndash33 35 36] None of the adverse events were seriousThese symptoms are self-limited and did not affect treatment
4 Discussion
Thismeta-analysis included 14 studies with 1170 total partici-pants comparing breviscapine injection plus antihypertensivedrugs versus antihypertensive drugs alone for hypertensivenephropathy Meanwhile the results demonstrated that theexpression levels of SCr and BUN were significantly lowerin patients treated with breviscapine injection in comparisonwith control subjects and the improvement of creatinineclearance was higher in patients treated with breviscapinein comparison with control subjects suggesting that thedrug serves as a protective role in the renal system ofpatients with hypertensive nephropathy Microalbuminuriais regarded as the earliest clinical sign of hypertensivenephropathy It is defined as a urinary albumin excretionrate ranging from 30 to 300mgday and the definitivemeasurement is based on a timed urine collection during

a 24-h period The present meta-analysis indicated thatbreviscapine injection can reduce 24-hour urinary proteinand the urinary beta-2-microglobulin a reduction in uri-nary protein may contribute towards the renal protectiveeffect of breviscapine injection in patients with hyperten-sive nephropathy Our analysis revealed that experimentalgroups showed better overall clinical efficacy than controlgroups
Erigeron breviscapus is a kind of traditional Chinesemedicine It was first recorded in the book of ldquoYunnan Mate-ria Medicardquo According to Chinese medicine theory erigeronbreviscapus is cold-natured sweet bitter and pungent intaste with the function of clearing heat relieving toxic-ity eliminating wind and dampness activating blood andremoving stasis expediting channel and activating meridianrelieving inflammation and alleviating pain The monomercomponent of Chinese herbal medicine (CHM) also knownas the natural pure compound drug has recently attractedmuch attention The natural extract artemisinin and itsderivatives are good examples of monomer components ofCHM that can treat diseases through various activities andcan be a good starting point to uncover the mechanism oftraditional Chinese medicine
Hypertensive renal injury is major target-organ damagedue to sustained high BP Long-term hypertension cancause renal sclerosis and gradually progress to chronic renalfailure Positive control of hypertension is the key to pre-venting hypertensive renal damage According to Chinesemedicine theory hypertensive renal injury is strongly relatedto fluid phlegm and dampness retention syndrome andliver-yang hyperactivity syndrome which are caused bydeficiency syndrome Chinese medicines which are usedto treat fluid phlegm and dampness retention syndromedeficiency syndrome and liver-yang hyperactivity syndromerespectively have certain advantages with regard to treatinghypertensive renal injury [45] Clinical research indicatesthat Chinese herbal medicine might control increased SBPinhibit the glomerular and tubular hyperplasia caused byhigh BP and significantly reduce urinary albumin and beta-2-microglobulin by increasing the activity of renal rennin andthe level of Ang II [46 47]

3410 Adverse Effects Nine of the included trials [29ndash36 38]described adverse effects in detail while the others did notmention adverse eventsOnly one showedmild facial flushingduring intravenous dripping of breviscapine [30] and afterthe speed of transfusion was slowed down the symptom gotremitted Two cases [38] showed redness of limb skin in theexperimental group There were two cases [31 32] of headinflation during the use of antihypertensive drugsTherewerethree cases [33 34] of head swelling and dizziness duringinfusion during the use of breviscapine injection Twenty-onecases showed dry cough due to the use of ACEI in six trials[29 31ndash33 35 36] None of the adverse events were seriousThese symptoms are self-limited and did not affect treatment
4 Discussion
Thismeta-analysis included 14 studies with 1170 total partici-pants comparing breviscapine injection plus antihypertensivedrugs versus antihypertensive drugs alone for hypertensivenephropathy Meanwhile the results demonstrated that theexpression levels of SCr and BUN were significantly lowerin patients treated with breviscapine injection in comparisonwith control subjects and the improvement of creatinineclearance was higher in patients treated with breviscapinein comparison with control subjects suggesting that thedrug serves as a protective role in the renal system ofpatients with hypertensive nephropathy Microalbuminuriais regarded as the earliest clinical sign of hypertensivenephropathy It is defined as a urinary albumin excretionrate ranging from 30 to 300mgday and the definitivemeasurement is based on a timed urine collection during

a 24-h period The present meta-analysis indicated thatbreviscapine injection can reduce 24-hour urinary proteinand the urinary beta-2-microglobulin a reduction in uri-nary protein may contribute towards the renal protectiveeffect of breviscapine injection in patients with hyperten-sive nephropathy Our analysis revealed that experimentalgroups showed better overall clinical efficacy than controlgroups
Erigeron breviscapus is a kind of traditional Chinesemedicine It was first recorded in the book of ldquoYunnan Mate-ria Medicardquo According to Chinese medicine theory erigeronbreviscapus is cold-natured sweet bitter and pungent intaste with the function of clearing heat relieving toxic-ity eliminating wind and dampness activating blood andremoving stasis expediting channel and activating meridianrelieving inflammation and alleviating pain The monomercomponent of Chinese herbal medicine (CHM) also knownas the natural pure compound drug has recently attractedmuch attention The natural extract artemisinin and itsderivatives are good examples of monomer components ofCHM that can treat diseases through various activities andcan be a good starting point to uncover the mechanism oftraditional Chinese medicine
Hypertensive renal injury is major target-organ damagedue to sustained high BP Long-term hypertension cancause renal sclerosis and gradually progress to chronic renalfailure Positive control of hypertension is the key to pre-venting hypertensive renal damage According to Chinesemedicine theory hypertensive renal injury is strongly relatedto fluid phlegm and dampness retention syndrome andliver-yang hyperactivity syndrome which are caused bydeficiency syndrome Chinese medicines which are usedto treat fluid phlegm and dampness retention syndromedeficiency syndrome and liver-yang hyperactivity syndromerespectively have certain advantages with regard to treatinghypertensive renal injury [45] Clinical research indicatesthat Chinese herbal medicine might control increased SBPinhibit the glomerular and tubular hyperplasia caused byhigh BP and significantly reduce urinary albumin and beta-2-microglobulin by increasing the activity of renal rennin andthe level of Ang II [46 47]

6 Conclusions
Evidence from this systematic review shows that breviscap-ine injection in combination with antihypertensive drugscan improve clinical efficacy and creatinine clearance rate

Figure 10 Meta-analysis results of breviscapine injection plus antihypertensive drugs versus antihypertensive drugs alone in terms of beta-2-microglobulin for hypertensive nephropathy
Figure 11 Meta-analysis results of breviscapine injection plus antihypertensive drugs versus antihypertensive drugs alone in terms of the SBPfor hypertensive nephropathy
strictly monitored and properly reported in future clinicaltrialsThird all tests produced positive results althoughmosttests were conducted with small samples We tried our best toavoid language bias and positional prejudice but cannot ruleout potential publication bias
Overall our results suggest that breviscapine injection iseffective and safe for the treatment of hypertensive nephropa-thy and this work has reference value for clinicians Morelarge-scale multicenter rigorously designed randomized
controlled trials are needed to provide accurate data tofurther validate the effectiveness and safety of breviscapineinjection
6 Conclusions
Evidence from this systematic review shows that breviscap-ine injection in combination with antihypertensive drugscan improve clinical efficacy and creatinine clearance rate
