This research aimed to study the inhibitory effect of Glurenorm (gliquidone) on epithelial-to-mesenchymal-transition (EMT) of renal tubular epithelial cells based on the diabetic nephropathy (DN) model. In this study, 30 specific pathogen-free (SPF) mice were selected to construct DN model and randomly rolled into groups A, B, and C, with 10 mice in each group. Low-dose, mediumdose, and high-dose Glurenorm were administered intragastrically. The results showed that the serum urea nitrogen content (7.23±0.39 mmol/L, 6.18±0.46 mmol/L) of control and C group was considerably inferior to A group (8.01±0.48 mmol/L), and the content of C group was greatly lower than controls (P < 0.05). The creatinine clearance rate (2.97±0.44 mL/min, 4.02±0.31 mL/min) of mice in control and C group was notably superior to A group (2.18±0.38 mL/min), and that of C group was obviously higher versus controls (P < 0.05). After 5 weeks of intragastric intervention by Glurenorm, the body mass of the mice in control and C group was evidently lower relative to A group, and that of C group was obviously higher versus controls (P < 0.05). Mice in control and C group were remarkably lower in body mass at the 7th week after Glurenorm intervention versus A group, and C group was relatively lower versus controls (P < 0.05). In short, EMT played an important role in promoting the occurrence and progression of renal fibrosis. Glurenorm can reduce the progression of renal fibrosis, inhibit EMT of renal tubular epithelial cells, and effectively protect kidney function.
