ObjectiveTo assess the safety and effect on elevated blood lipid levels of Baduanjin exercises in middle-aged and elderly individuals.MethodsA systematic literature search for articles up to March 2017 will be conducted using seven databases: PubMed, Embase, Cochrane Library, Chinese National Knowledge Infrastructure, Chinese Science and Technology Periodicals Database, Chinese BioMedical Database and Wanfang Data. Inclusion criteria are randomised controlled trials of Baduanjin exercises that examine blood lipid levels in middle-aged and elderly individuals. The primary outcome measures will be total cholesterol, triglycerides, low-density lipoprotein cholesterol and high-density lipoprotein cholesterol. Stata V.13.0 software will be used for data synthesis, sensitivity analysis, metaregression, subgroup analysis and risk of bias assessment. A funnel plot will be developed to evaluate reporting bias and Begg and Egger tests will be used to assess funnel plot symmetries. We will use the Grading of Recommendations Assessment, Development and Evaluation system to assess the quality of evidence.Ethics and disseminationThis systematic review will be submitted to a peer-reviewed journal. Our findings will provide information about the safety of Baduanjin exercises for middle-aged and elderly individuals and their effect on elevated blood lipid levels.Trial registration numberPROSPERO CRD 42017060613.
Objective To assess the effects and safety of berberine combined with triple therapy on Helicobacter pylori (H. pylori) eradication in adults. Methods PubMed, MEDLINE, EMBASE, Cochrane Library, and Chinese databases including China National Knowledge Infrastructure (CNKI), Wanfang data, Chinese Technology Journal Full-text Database (VIP), and China biomedical literature database (CBM) were searched to obtain the eligible studies published up to October 10, 2017. The primary outcome was eradication rate of H. pylori. The secondary outcome was incidence of adverse effects. Data analysis was conducted by RevMan5.2 and Stata V.9.0 software. Trial sequential analysis (TSA) was performed to assess the risk of random error and the validity of conclusion with TSA program version 0.9 beta. Results The meta-analysis results indicated berberine combined with triple therapy could improve the eradication rates of H. pylori (urea breath test subgroup: RR=1.18, 95%CI=(1.12,1.24), P < 0.00001, biopsy subgroup: RR=1.23, 95%CI=(1.13,1.34), P < 0.00001) and reduce the total occurrence of adverse effects (OR=0.59, 95%CI(0.46, 0.75), P < 0.0001) when compared with only using triple therapy. Besides, the incidence of nausea (OR=0.59, 95%CI(0.41, 0.86), P < 0.05) and diarrhea (OR=0.41, 95%CI(0.24, 0.71) was remarkably lower in experimental group while that of abdominal distention (OR=0.64, 95%CI(0.40,1.04), P > 0.05) and vomiting (OR=0.65, 95%CI(0.37, 1.15), P > 0.05) had no significant change. TSA of H. pylori eradication rates and adverse effects incidence illustrated that the cumulative value of Z-curve went across the conventional boundary value, trial sequential monitoring boundary for benefit, and required information size, suggesting the results were stable. Conclusion Evidence from meta-analysis suggested that berberine combined with triple therapy can be an option for increasing H. pylori eradication rates and reducing overall therapy-related adverse effects incidence, particularly nausea and diarrhea, whereas more randomized controlled trials designed according to CONSORT statement are demanded to support the efficacy in further studies.
ObjectiveTo assess the efficacy and safety of Nuanxin capsule for patients with heart failure (HF).MethodsA systematic literature search was performed in 6 databases: PubMed, EMBASE, Chinese National Knowledge Infrastructure (CNKI), Wan-fang Data Information Site, Chinese BioMedical Database (CBM), VIP Chinese Science and Technique Journals Database from the date of its inception up to November 2016. Review Manager 5.2 software was used for assessment of risk of bias, data synthesis and subgroup analysis. Begg and Egger tests were used for assessing symmetries of funnel plot by software Stata 12.0. We conducted the GRADE system to assess the quality of evidence.Results12 trials involving 1418 participants were eligible. Compared with western medicine (WM) alone, Nuanxin capsule plus WM showed statistical significance in total effective rate (RR 1.18, 95% condidence interval [CI] 1.13–1.25). According to subgroup analysis, the 6-months group and the 12-months group have better effect than the 3-month group. As for 6-minute walking distance (6MWT), Nuanxin capsule plus WM compared with WM has significantly increased walking distance (weighted mean difference [WMD] 42.56, 95% CI 34.27–50.85). Nuanxin capsule plus WM has significantly decreased in mortality (RR 0.29, 95% CI 0.18–0.46) and re-admission rate (RR 0.48, 95% CI 0.39–0.60) compared with WM. Nuanxin capsule plus WM was beneficial for B-type natriuretic peptide (−240.47, 95% CI −332.45–148.49). gger's and Begg's test showed that there was no publication bias exist (P = .937). Influence analysis showed that no single study affected the overall result. The GRADE quality of the evidence was very low to Moderate across the different outcomes.ConclusionsDespite of the apparently positive findings, we cannot draw a sound conclusion that Nuanxin capsule has positive effect in patients with HF, because of the insufficient evidence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
