Abstract:This study focused on the clinical effects of glimepiride combined with metformin or acarbose in the treatment of type 2 diabetes.The control group was treated with glimepiride combined with acarbose, while the observation group was treated with glimepiride combined with metformin. The changes of blood sugar, islet function, lipid level and oxidative stress were observed after treatment in both groups.The results showed that the glimepiride combined with metformin treatment group had significant hypoglycemic effect, HOMA-IR and HOMA-β were significantly increased, and TG decreased, and MAGE, 3-NT and CRP decreased significantly. Overall, glimepiride combined with metformin in the treatment of type 2 diabetes has improved blood glucose levels, and it can also significantly improve insulin-related indicators, clinically more effective, which is better than combined acarbose.
