Objective To investigate therapeutic efficacy of GLP-1 receptor agonist combined with dapagliflozin in treating obese type 2 diabetes mellitus ( T2DM) and the effect on islet function. Methods A total of106 obese patients with T2DM were randomly divided into a control group and an observation group. Control group was treated with dapagliflozin,while the observation group was treated with GLP-1 receptor agonist combined with dapagliflozin. Glucose oxidase method was applied to measure fasting blood glucose ( FPG ) and 2-hour postprandial blood glucose ( 2 hPG ) before and after treatment. Chromatography was used to examine glycated hemoglobin ( HbA1c). Triglycerides( TG),and total cholesterol ( TC ) were measured using oxidase method and enzyme colorimetric method,respectively. Blood glucose level after treatment was used to evaluate clinical efficacy. The height,body mass and body mass index ( BMI) were compared before and after treatment between two groups of the patients. Fasting insulin ( FINS) of two groups was before and after treatment measured. Insulin resistance index ( HOMA-IR ) and pancreatic β cell function ( HOMA-β) were calculated based on the results of FINS and FPG tests. The occurrence of adverse reactions in two groups was recorded. Results After treatment,the levels of FPG,2 hPG,HbA1c,TG,and TC in observation group were lower than those in control group (P<0.05). After 3 months of treatment,the total effective rate of treatment was significantly higher in observation group than that of control group (90.6% versus 75. 5%,P<0.05). After treatment,FINS and HOMA-IR were lower in observation group than those in control group,while HOMA-β was higher than that in control group (P<0.05). After treatment,BMI of observation group was lower than that of control group (P<0.05). There was no statistically significant difference in the incidence of adverse reactions between two groups ( P>0.05 ).Conclusion The combination of GLP-1 receptor agonists and dapagliflozin has a good therapeutic effect on obese T2DM,and its mechanism might be related to regulating glucose and lipid metabolism in patients,protecting islet function.
