We examined the impact of YSHZ injection on the genes expressions of fibronectin(FN) and plasminogen activator inhibitor 1(PAI 1) mRNA in human glomerular mesangial cells incubated in high glucose.The expressions of fibronectin and PAI 1 mRNA were determined by northern blot analysis.The level of fibronectin in the mesangial cell supernatant was assayed through the sandwich ELISA method.The results showed that YSHZ injection could significantly antagonize the increased mRNA expressions of fibronectin an...
