Objective:To study the efficacy of Chinese medicine(CM) on isolated systolic hypertension.Methods:Seven electronic databases were searched for randomized controlled trials(RCTs) published until August 2015.Subgroup analyses and meta-analysis were performed to assess the efficacy and safety of the included studies.Results:A total of 24 studies,including 2,096 patients(1,058 patients in the intervention group and 1,038 in the control group),were evaluated in the final analysis.Compared with a conventional therapy used alone,CM as additional intervention was more effective on systolic blood pressure[mean difference(MD)=-0.66,95%confidence interval(CI)=(-0.97,-0.36),P<0.00001]and significantly diminished the pulse pressure[MD=-7.49,Cl=(-12.69,-2.29),P<0.00001].However it showed no additional benefit on diastolic blood pressure[MD=1.16,CI=(0.02,2.29),P=0.87].Adverse events were not explicitly reported in most RCTs.Conclusions:CM might be a promising approach for the elderly with isolated systolic hypertension,while the evidence for CM employed alone was insufficient.Considering the inherent limitations of the included studies,larger high-quality RCTs with extensive follow-up should be performed to validate our findings in the future.
Objective:To explore the medication law of traditional Chinese medicine compound patent for hyperlipidemia,and to provide reference for the research and development of traditional Chinese medicine new drugs for clinical treatment of hyperlipidemia.Methods:All compound TCM patents related to the treatment of hyperlipidemia were searched and extracted from the national patent database(http://epub.sipo.gov.cn)from the establishment of the database to 10st,March 2021.The data was established by the TCM Inheritance Support System(V2.5)and Microsoft Excel 2010 Softwore,and used to conduct TCM syndromes,frequency statistics,four nature and five flavors of traditional Chinese medicine,meridian attribution statistics.IBM SPSS statistics 20 software was used for drug clustering analysis,IBM SPSS modeler 18.2.2 software was used for association rules and web visualization analysis.Results:Totally 284 compound TCM patents were included,involving 577 kinds of Chinese medicine,and the most common syndrome was Yin deficiency of liver and kidney syndrome(74 times,accounting for 26.06%).The most ten common Chinese materiamedica was Hawthorn,Salvia miltiorrhiza,Alismaorientalis,Cassia seed,Polygonummultiflorum,Licorice,Poriacocos,chinese rhubarb,dried tangerine peel,Radix Paeoniae Alba.The top three appeared frequently in drug categories were tonifying deficiency medicine,activating blood-circulation and dissipating blood-stasis medicine,and heat-clearing medicine,respectively.The top two of its drug properties were warm and cold;the top three drug tastes were sweet,bitterness and pungent;the top two meridians were liver and spleen meridian,respectively.Seven drug groups were obtained by cluster analysis,and 16 were obtained by association rule analysis,including 5 drug pairs and 11 three drug groups.Conclusion:Through the data mining of the patent of traditional Chinese medicine compound prescription for regulating and treating hyperlipidemia,it is concluded that the fundamental pathogenesis of the disease is deficiency of viscer
