Background: With the development of social economy, people's lives are improving day by day. Chronic diseases represented by diabetes have gradually entered people's field of vision. At present, about 415 million people in the world suffer from diabetes, of which more than 90% are Type 2 diabetic mellitus (T2DM), which causes severe physical and mental pain to patients and their families, and also imposes a huge burden on the health care system. Animal experiments and clinical studies both show that Gegen Qinlian Decoction (GQD) cannot only reduce the blood glucose of T2DM, but also improve the islet function of patients, reduce the insulin resistance index and insulin secretion index, and have no adverse reactions. Therefore, we designed this protocol to evaluate the effect of GQD on clinical Prognosis and islet function for T2DM. Methods: This review was conducted from January 1, 2000 to October 1, 2020, sourced from the Cochrane Library, Pubmed, Excerpt Medica Database, Science Direct, World Health Organization, International Clinical Trials Registration Platform, Web of Science, Chinese Biomedical Literature, the China National Knowledge Infrastructure Database, Wanfang Database, Chinese Scientific Journal Database. In this study clinical randomized controlled trial is used and we set inclusion criteria and exclusion criteria for screening. The primary outcomes include Fasting plasma glucose,2 h plasma glucose, Hemoglobin A1c, fasting plasma insulin, insulin resistance index and insulin secretion index. Review Manager 5.3 software will be used for data analysis. Results: This study will provide the systematic evidence of the effect of GQD on Clinical Prognosis and islet function for T2DM. Conclusion: The findings of this meta-analysis will provide evidence to evaluate the effect of GQD on Clinical Prognosis and islet function for type 2 diabetic mellitus.

Citri Reticulatae Pericarpium (CRP), also known as “chenpi”, is the most common qi-regulating drug in traditional Chinese medicine. It is often used to treat cough and indigestion, but in recent years, it has been found to have multi-faceted anti-cancer effects. This article reviews the pharmacology of CRP and the mechanism of the action of flavonoids, the key components of CRP, against cancers including breast cancer, lung cancer, prostate cancer, hepatic carcinoma, gastric cancer, colorectal cancer, esophageal cancer, cervical cancer, bladder cancer and other cancers with a high diagnosis rate. Finally, the specific roles of CRP in important phenotypes such as cell proliferation, apoptosis, autophagy and migration–invasion in cancer were analyzed, and the possible prospects and deficiencies of CRP as an anticancer agent were evaluated.

Backgroud: Ulcerative colitis (UC) is a chronic inflammatory disease that involves the rectum, colon and ileum. Gancao Xiexin decoction (GCXXD) is a classic herbal formula in Shanghanlun. More and more research evidence shows that GCXXD has a certain therapeutic effect on UC. Therefore, we designed this study protocol aim to evaluate the efficacy and safety of GCXXD combine with mesalazine for UC. Methods: We will systematically search 6 databases, including PubMed, the Cochrane Library, EMBASE, CNKI, VIP, Wang-fang database up to July 2020 to obtain eligible studies. The primary outcomes will focus on the clinical effectiveness. Review Manager 5.3 software will be used for data analysis. Results: This study will provide the systematic evidence of UC treated with GCXXD combine with mesalazine. Conclusion: The findings of this meta-analysis will provide evidence to judge whether GCXXD combine with mesalazine is a more effective intervention compare to mesalazine only for patient of UC.

Background: Accumulated evidence indicates that astragalus polysaccharide (APS) may have a beneficial impact on ulcerative colitis (UC) by suppressing inflammation and decreasing oxidative stress. Nevertheless, the credibility of the evidence for this practice is unclear. Therefore, we intended to conduct a systematic review and meta-analysis of animal studies to assess the anti-inflammatory and antioxidant activity of APS when used in the treatment of UC.Methods: Electronic bibliographic databases including PubMed, EMBASE, Web of Science, Chinese Biomedical Literature (CBM), Wanfang Database, CQVIP Database and China National Knowledge Infrastructure (CNKI) were retrieved for relevant animal studies. The methodological quality of animal studies was evaluated based on the SYstematic Review Center for Laboratory animal Experimentation (SYRCLE’s RoB tool). A meta-analysis was performed according to the Cochrane Handbook for Systematic Reviews of Interventions by using STATA 12.0 software. This study was registered with PROSPERO, number CRD42021272595.Results: Twenty qualified publications involving 591 animals were included in this study. There was a significant association of APS with levels of disease activity index (DAI), colon macroscopic damage index (CMDI), colon histopathologic score (CHS), myeloperoxidase (MPO), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-1β (IL-1β), superoxide dismutase (SOD) and malondialdehyde (MDA) compared with that in the control group. Sensitivity analysis that eliminated one study at each stage did not change these results. Egger’s test and funnel plot showed that publication bias was existed.Conclusion: In this meta-analysis, APS treatment significantly mitigated colonic damage by reducing the levels of MPO, TNF-α, IL-6, IL-1β, and MDA and recovering the SOD activity. These results demonstrated a protective role of APS in the treatment of UC and showed that the anti-inflammatory and antioxidant activity were implicated in the underlying mechanisms. Hence, APS may represent a promising candidate for treating UC. However, due to potential publication bias, a cautious interpretation is needed.Systematic Review Registration: (https://www.crd.york.ac.uk/PROSPERO/).
