The main purpose of this study is to explore the improvement of renal function before and after the intervention of dorzagliatin in patients with type 2 diabetes.
As soon,metformin、SGLT-2i、GLP-1RA have been confirmed to have protective effect on the kidneys in the statement of consensus at home and abroad. Dorzagliatin exerts a potent hypoglycemic effect by activating glucokinase and is not affected by the patient's renal function. However, previous studies of this drug have rarely involved studies that improve markers related to renal function. On the one hand, in this study, changes of renal function (eGFR, creatinine, cystatin C, TNF-1) are collected to investigate whether dorzagliatin is benefit to kidney. On the other hand, renal magnetic resonance imaging(MRI) results are analysed to explore the differences among control subjects and patients treated with dorzagliatin.
