ABSTRACT
Background: Obesity is considered one of the biggest public health problems, especially in the background of the coronavirus disease 2019 (COVID-19) lockdown. It is urgent to find interventions to control and improve it. We performed this systematic review and meta-analysis to summarize the effect of traditional Chinese exercise on obesity. Methods: We searched PubMed, Embase, Cochrane Library, the China National Knowledge Infrastructure (CNKI), the Chinese Scientific Journal Database (VIP), the Chinese Biomedical Literature Database (CBM), and WanFang database for updated articles published from the inception of each database to June 2022. Randomized controlled trials (RCTs) on traditional Chinese exercise in weight reduction were included, and related data were extracted. The random-effects model was used to adjust for the heterogeneity of the included studies, and funnel plots were used to examine publication bias. Results: A total of 701 participants were included in the 10 studies. Compared with the control group, the outcome of body weight [mean difference (MD) = -6.10; 95% CI = -8.79, -3.42], body mass index (MD = -2.03; 95% CI = -2.66, -1.41), body fat mass (MD = -3.12; 95% CI = -4.49, -1.75), waist circumference (MD = -3.46; 95% CI = -4.67, -2.24), hip circumference (MD = -2.94; 95% CI = -4.75, -1.30), and waist-to-hip ratio (MD = -0.04; 95% CI = -0.06, -0.03) in the intervention group had significant differences. Egger's test and funnel plots showed that the potential publication bias of the included studies was slight (p = 0.249). Conclusion: Traditional Chinese exercise is an effective treatment for obesity; people under the COVID-19 lockdown could do these exercises to control weight. However, a precise and comprehensive conclusion calls for RCTs on a larger scale with more rigorous designs considering the inferior methodological quality and limited retrieved articles.

Background: Hidden blood loss (HBL) after total hip arthroplasty (THA) would lead to many undesirable consequences. Traditional Chinese medicine (TCM) is now increasingly used for hidden blood loss. We performed this systematic review and meta-analysis to summarize the effect and safety of TCM treatment of HBL after THA. Methods: We searched PubMed, Embase, Cochrane Library, CNKI, VIP, WanFang, and CBM for the updated articles published from the inception of each database to May, 2022, among which results such as abstracts, comments, letters, reviews, and case reports were excluded. The efficacy and safety of TCM treatment of HBL after THA were synthesized and discussed by the outcomes of total blood loss (TBL), hidden blood loss (HBL), hemoglobin (Hb), and hematocrit (HCT), and the incidence of adverse reactions. Results: A total of 12 articles and 881 patients were included. There were 441 cases in the intervention group and 440 cases in the control group. Compared with the control group, the intervention group had more advantages in TBL (MD = -251.68, 95% CI = [-378.36, -125]; Z = 3.89, P < 0.00001), HBL (MD = -159.64, 95% CI = [-252.56, -66.71]; Z = 3.37, P=0.0008), Hb (MD = 11.39, 95% CI = [7.35, 15.43]; Z = 5.53, P < 0.00001), and HCT (MD = 2.87, 95% CI = [0.97, 4.78]; Z = 2.95, P=0.003), and had less incidence of adverse reactions (OR = -0.20, 95% CI = [-0.35, -0.05]; Z = 2.64, P=0.008). Conclusion: TCM has advantages in the efficacy and safety of treating hidden blood loss after THA. The strength of the evidence of the research results is limited by the quality of the included literature, and more high-quality RCTs are needed to confirm.
