Systematic review and Meta-analysis on efficacy and safety of Gongxuening Capsules in treatment of abnormal vaginal bleeding after medical abortion / 中国中药杂志

To systematically evaluate the efficacy and safety of Gongxuening Capsules in the treatment of abnormal vaginal bleeding after medical abortion. CNKI, Wanfang, SinoMed, VIP, PubMed, Cochrane Library and EMbase databases were retrieved to comprehensively collect the clinical randomized controlled trials(RCTs) of Gongxuening Capsules for treatment of abnormal vaginal bleeding after medical abortion from the establishment of the databases to October 10, 2020. Literature screening, data extraction and quality evaluation were conducted independently by two system reviewers according to the inclusion and exclusion criteria. Cochrane Handbook bias risk assessment tool was used for the literature methodology quality evaluation, RevMan 5.3 software was used for Meta-analysis, and the evidence quality of outcomes was evaluated by the evidence quality grading system(GRADE). A total of 16 RCTs were inclu-ded. The results of Meta-analysis showed that as compared with the western medicine treatment alone, the addition of Gongxuening Capsules to the western medicine treatment can reduce the amount of vaginal bleeding(RR=1.23, 95%CI[1.19, 1.27], P<0.000 01), shorten vaginal bleeding time(RR_(≤15 d number of people)=1.39, 95%CI[1.31, 1.48], P<0.000 01; MD_(number ofdays)=-1.20, 95%CI[-1.66,-0.74],P<0.000 01). However, there was no obvious advantage in abortion effect(RR=1.02, 95%CI[0.99, 1.06], P=0.14) and menstrual recovery(MD=-0.35, 95%CI[-0.96, 0.25], P=0.25). The results of GRADE showed that the grading level was low for vaginal bleeding volume and vaginal bleeding time, and extremely low for abortion effect and mens-trual recovery. In terms of safety, 16 studies reported adverse events. Only one study showed no adverse events and the rest showed transient nausea, vomiting, stomach burning, upper abdominal discomfort and other gastrointestinal symptoms. The results show that the addition of Gongxuening Capsules to the application of western medicine in treatment of drug abortion can reduce the amount of vaginal bleeding and shorten vaginal bleeding time, but the abortion effect and menstrual recovery have no obvious advantages. The use of Gongxuening Capsules helps to achieve less adverse reactions and higher safety. Due to the small sample size of the included studies and many methodological quality problems, no conclusions with clinical guidance value can be obtained. Large sample-zise, high-qua-lity randomized controlled trials are still needed for further verification.

Systematic review of randomized controlled trial of Maxing Shigan Decoction in treatment of community acquired pneumonia / 中国中药杂志

To systemically evaluate the efficacy and safety of Maxing Shigan Decoction in the treatment of community acquired pneumonia(CAP) and provide a reference for the treatment of CAP. Databases of CNKI, Wanfang, VIP, SinoMed, EMbase, Cochrane Library, Web of Science and PubMed were searched(from inception to May 30, 2020) to screen the randomized controlled trials(RCTs) of Maxing Shigan Decoction in treating CAP. Two authors independently screened and selected relevant literature and extracted data based on the inclusion and exclusion criteria. Any disagreement or differences was resolved through discussion. The bias risk assessment tool recommended by Cochrane handbook was used to evaluate the quality of the included studies, and RevMan 5.3 software was used for data analysis. Seventeen RCTs were finally included, involving 1 309 patients. Meta-analysis showed that Maxing Shigan Decoction combined with conventional Western medicine treatment could improve clinical efficacy in patients with CAP more effectively as compared with conventional Western medicine treatment alone, mainly in terms of anti-inflammatory effects, a decrease in C-reactive protein(CRP) content(MD=-6.01, 95%CI[-10.95,-1.06], P=0.02)and white blood cell(WBC) count, a decrease in procalcitonin(PCT) level(MD=-0.74, 95%CI[-0.77,-0.71], P<0.000 1), and shortened recovery time of cough and fever. Maxing Shigan Decoction has certain curative effect on CAP, but there are problems in the methodology of included studies. High-quality stu-dies are still needed for further verification.
