Review Meta Analysis
Green tea as a safe alternative approach for nonalcoholic fatty liver treatment: A systematic review and meta-analysis of clinical trials.
This study aimed to evaluate the efficacy of green tea supplementation on nonalcoholic fatty liver disease treatment. Electronic databases, including PubMed, Scopus, Web of Science, and Google Scholar, were systematically searched up to October 30, 2017, to identify eligible trials based on the inclusion criteria. ⋯ Likewise, a favorable effect of green tea administration was observed on body mass index (-2.08 kg/cm2 ; 95% CI: -2.81 to -1.36), triacylglycerol (-31.87 mg/dl; 95% CI: -40.62 to -23.12), total cholesterol (-27.57 mg/dl; 95% CI: -36.17 to -18.98), and low-density lipoprotein cholesterol (-14.15 mg/dl; 95% CI: -23.69 to -4.60), whereas no significant effect was detected on high-density lipoprotein cholesterol concentrations (7.41 mg/dl; 95% CI: -1.49 to 16.30) and homeostasis model assessment of insulin resistance (-4.06; 95% CI: -10.22 to 2.09). This systematic review and meta-analysis of available trials suggests that there are potential benefits of green tea supplementation on nonalcoholic fatty liver disease.

Review Meta Analysis
Panax notoginseng Preparations for Unstable Angina Pectoris: A Systematic Review and Meta-Analysis.
This paper assessed the evidence of Panax notoginseng preparations in patients suffering from UAP using meta-analysis and systematic review methods. Methods were according to the Cochrane Handbook and analysed using Revman 5.3. A search of PubMed, Cochrane Library, Embase, MEDLINE, Chinese national knowledge infrastructure (CNKI), Vip information database, Wanfang data and Chinese Biomedical Literature Database (SinoMed) was conducted to identify randomized controlled trials (RCTs) of P. notoginseng preparations on UAP regardless of blinding, sex and language. ⋯ Cardiac mortality and duration of angina pectoris were not statistically significant. Panax notoginseng is beneficial to UAP patients; the results of these reviews may have important implications to clinical work. Copyright © 2017 John Wiley & Sons, Ltd.

Review Meta Analysis
Dang shen [Codonopsis pilosula (Franch.) Nannf] herbal formulae for chronic obstructive pulmonary disease: a systematic review and meta-analysis.
This systematic review and meta-analysis assessed the efficacy and safety of Dang shen [Codonopsis pilosula (Franch.) Nannf., root] formulae for the treatment of chronic obstructive pulmonary disease (COPD). English and Chinese databases were searched, and 48 randomized controlled trials were included. Dang shen formulae improved lung function forced expiratory volume in 1 s compared with conventional pharmacotherapy (CP) [mean difference (MD) 0.22 L, 95% confidence interval (CI) 0.13-0.31, p < 0.001, I(2) = 5%] and quality of life (St. ⋯ Dang shen formulae appear to improve some aspects of the included COPD outcomes. However, owing to methodological flaws, the current evidence is inadequate to support the routine use of Dang shen formulae outside of Chinese medicine practice. However, these results justify further investigation.

Review Meta Analysis
Are curcuminoids effective C-reactive protein-lowering agents in clinical practice? Evidence from a meta-analysis.
Inflammation plays a pivotal role in the pathogenesis of atherosclerosis and cardiovascular disease (CVD). In this context, C-reactive protein (CRP) has been identified as a strong predictor and independent risk factor of CVD. Curcuminoids are multifunctional natural product with promising cardioprotective and anti-inflammatory properties. Curcuminoids have been suggested to lower circulating levels of CRP, but clinical findings have not been consistent. ⋯ Supplementation with curcuminoids may reduce circulating CRP levels. This effect appears to depend on the bioavailability of curcuminoids preparations and also duration of supplementation. Future well-designed and long-term trials are warranted to verify this effect of curcuminoids.
