Meta-analysis-based systematic review of effect of traditional Chinese medicine intervention in treatment of diabetic nephropathy on thyroid function.

BACKGROUND: This research sought to systematically evaluate the clinical effects of traditional Chinese medicine (TCM) intervention in the treatment of diabetic nephropathy (DN) and analyze changes in thyroid function in patients with DN. METHODS: The PubMed, Embase, Medline, Ovid, Springer, and self-built databases were searched to screen literature on TCM intervention and the treatment of DN published from the establishment of the databases to January 1, 2021. The Cochrane Handbook for Systematic Reviews of Intervention 5.0.2 was then employed to assess the risk of bias in literature, and Review Manager 5.3 was utilized for the meta-analysis. RESULTS: A total of 20 randomized controlled trials (RCTs) were included in the study, involving 3,566 subjects, and meta-analysis results showed that the clinical treatment efficiency of the experimental group was dramatically higher than the control group [MD =6.22, 95% confidence interval (CI): 3.77-10.25, Z=7.17, P<0.00001]. Moreover, the serum creatinine (Scr), blood urea nitrogen (BUN), urine protein excretion rate (UAER), 24 h postoperative urine protein quantification, and tumor necrosis factor-alpha (TNF-α) of patients after TCM intervention were all remarkably inferior to those of the control group as seen in the following results: Scr, MD =-8.69, 95% CI: -9.92 to -7.47, Z=13.94, P<0.00001; BUN, MD =-1.74, 95% CI: - 2.48 to -1.00, Z=4.6, P<0.00001; UAER, MD =-26.16, 95% CI: -46.89 to -5.44, Z=2.47, P=0.01; 24 h postoperative urine protein quantification, MD =-0.54, 95% CI: -0.68 to -0.4, Z=7.4, P<0.00001; TNF-α, MD =-5.3, 95% CI: -9.15 to -1.46, Z=2.7, P=0.007; and high sensitivity C-reactive protein (hs-CRP), MD =-1.34, 95% CI: -1.9 to -0.78, Z=4.66, P<0.00001. DISCUSSION: TCM intervention in DN is effective in treating the clinical symptoms of patients with this disease and has ideal therapeutic effects.

Multiple dietary fiber for gestational hyperinsulinism: A protocol of systematic review and meta-analysis of randomized clinical trials.

INTRODUCTION: Gestational hyperinsulinism is a metabolic disease which is widely concerned at home and abroad. It is a clinical consensus that the embryo implantation ability of patients with hyperinsulinemia is decreased and the abortion rate after implantation is high. The treatment of gestational hyperinsulinism with Multiple dietary fiber diets has been proven. However, due to the lack of evidence, there is no specific method or recommendation, it is necessary to carry out a systematic evaluation of Multiple dietary fiber diet, to provide effective evidence for further research. METHODS AND ANALYSIS: The following databases will be searched from their inception to August 2020: Electronic database includes PubMed, Embase, Cochrane Library, Web of Science, Nature, Science online, Chinese Biomedical Database WanFang, VIP medicine information, and CNKI. Primary outcomes: Fasting glucose, fasting insulin, homeostasis model assessment of insulin resistance, glycosylated hemoglobin. Additional outcomes: Low Density Lipoprotein (LDL), High Density Lipoprotein (HDL), triglycerides (TG), total serum cholesterol (TC). Data will be extracted by 2 researchers independently, risk of bias of the meta-analysis will be evaluated based on the Cochrane Handbook for Systematic Reviews (SR) of Interventions. All data analysis will be conducted by data statistics software Review Manager V.5.3. and Stata V.12.0. RESULTS: The results of this study will systematically evaluate the effectiveness and safety of Multiple dietary fiber diet interventions in the treatment of gestational hyperinsulinism. CONCLUSION: The SR of this study will summarize the current published evidence of Multiple dietary fiber for the treatment of gestational hyperinsulinism, which can further guide the promotion and application of it. ETHICS AND DISSEMINATION: This study is a SR, the outcomes are based on the published evidence, so examination and agreement by the ethics committee are not required in this study. We intend to publish the study results in a journal or conference presentations. OPEN SCIENCE FRA NETWORK (OSF) REGISTRATION NUMBER: August 19, 2020. osf.io/tbc7z. (https://osf.io/tbc7z).

Huang Lian for ulcerative colitis: A protocol of systematic review and meta-analysis of randomized clinical trials.

INTRODUCTION: Ulcerative Colitis is a chronic nonspecific inflammatory disease of the colon and rectum, which is of global concern. It has the characteristics of a long course of disease and repeated attacks, which seriously affects the quality of life and economic and social development of the affected population. The treatment of UC by herb Huanglian and compound prescription contain Huanglian have been proved. However, due to the lack of evidence, there is no specific method or suggestion, it is necessary to systematically evaluate coptidis so as to provide effective evidence for further research. METHODS AND ANALYSIS: The following databases will be searched from their inception to June 2020: Electronic databases included PubMed, Embase, Cochrane Library, Web of Science, Nature, Science Online, WanFang China Biomedical Database, VIP Medical Information, CNKI (Knowledge Infrastructure of China). MAIN OUTCOMES: Colonoscopy, improved condition (tenesmus), stool routine. Additional outcomes: Electrocardiogram (ECG), erythrocyte (RBC), leukocyte (WBC), platelet (PLT). Data will be extracted by 2 researchers independently, risk of bias of the meta-analysis will be evaluated based on the Cochrane Handbook for Systematic Reviews of Interventions. All data analysis will be conducted by data statistics software Review Manager V.5.3. and Stata V.12.0. RESULTS: The results of this study will systematically evaluate the efficacy and safety of rhizoma coptidis intervention in patients with Ulcerative Colitis. CONCLUSION: Through the systematic review of this study, the published evidence of rhizoma coptidis on the treatment of UC is summarized so as to further guide its promotion and application. ETHICS AND COMMUNICATION: This study is a systematic review, the outcomes are based on the published evidence, so examination and agreement by the ethics committee are not required in this study. We intend to publish the study results in a journal or conference presentations. OPEN SCIENCE FRA MEWORK (OSF) REGISTRATION NUMBER: August 27, 2020. osf.io/7nh3k (https://osf.io/7nh3k).
