Abstract Objective To establish the early diabetic nephropathy (DN) rat model induced by high-fat and high-glucose and low dose of Streptozocin (STZ), so as to simulate the pathologic and renal function changes of early DN. Methods Thirty SPF level of normal male SD rats were divided into normal group and model group by weight. Normal group was fed with normal diet, model group was fed with high-fat and high-glucose diet for 8 weeks continuously, then 35 mg/kg of STZ was injected intraperitoneally to establish diabetic rats model, after that, high-fat and high-glucose diet was fed for 4 weeks continuously. Renal pathological changes, biochemical and renal function indexes of two groups were observed. Results The body weight of rats in the model group was significantly lower than that of normal group (P ＜ 0.01), while the random blood glucose level was higher than that of normal group (P ＜ 0.01), which had reached to standard of diabetes mellitus. The level of serum insulin in the model group was lower than that of normal group, the values of relative kidney weight, 24 h microalbuminuria, α1-microglobulin, β2-macroglobulin were higher than those of normal group, the differences were highly statistically significant (P ＜ 0.01). The pathological characteristics of model group presented the thickening of glomerular basement membrane, mesangial broadening, accumulation of glycogen and collagen fiber in both glomerulus and kidney tubules. Conclusion This molding method can imitate the basic characteristics of early DN.
