September 19, 2025 updated by: Yanbing Li, Sun Yat-sen University

Effects of Oral Hypoglycemic Agents Combined With Short-term CSII on Glycemic Control in Newly-diagnosed Type 2 Diabetic Patients

The purpose of this study is to investigate and evaluate the effects of different oral antihyperglycaemic agents combined with short-term continuous subcutaneous insulin infusion(CSII)(1.CSII alone; 2.metformin and pioglitazone combined with CSII; 3. sitagliptin combined with CSII) on long-term glycemic control and β-cell function in newly diagnosed type 2 diabetic patients.
