On the basis of conventional treatment, control group of patients received benazepril therapy, observation group of patients received calcium dobesilate combined with benazepril therapy, and the treatment lasted for 3 months. Before and after treatment, automatic biochemical analyzer was used to detect the levels of renal injury indexes in peripheral blood, RIA method was used to detect the levels of renal injury indexes in urine, ELISA method was used to detect the levels of renal fibrosis indexes and Western-blot method was used to detect the protein expression of TGF-β1/BMP-7 and Smad signaling pathway molecules in renal tissue. Results: Before treatment, differences in renal injury index levels, renal fibrosis index levels and signaling pathway molecule protein expression were not statistically significant between two groups of patients. After treatment, BUN, SCr andβ-TP levels in the peripheral blood as well as KIM-1 level in urine of observation group were lower than those of control group;renal fibrosis indexes TGF-β1, CTGF, TIMP-1, LN and HA levels in serum of observation group were lower than those of control group;TGF-β1 and Smad2/3 protein expression in renal tissue of observation group were lower than those of control group while Smad7 and BMP-7 protein expression were higher than those of control group.Conclusion: Calcium dobesilate combined with benazepril therapy can reduce the renal injury and inhibit the fibrosis process in patients with early diabetic nephropathy, and it achieves the above effect by regulating the TGF-β1/BMP-7 and Smad signaling pathway function.展开更多
