The effect of Gegen Qinlian Decoction on clinical prognosis and islet function for type 2 diabetic mellitus: A protocol for systematic review and meta-analysis

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.
