In prevention stage, comparing with normal control group, triglycerides, blood sugar (BG), 24-hour urinary protein and cholesterol (CHO) were higher in T2DM group, but weight and urea nitrogen (BUN) was less in it. 24-hour urinary protein and cholesterol (CHO) were higher in T2DM group than the intervention group. 24-hour urinary protein and BG in the intervention group were higher than normal control group, but BUN is less than normal control group; In the intervention group the weight of kidney and weight of rat were also higher than T2DM group, but CHO and 24-hour urinary protein were less than T2DM group. The expression of TGF-β1 in T2DM group were more than the other groups. In treatment stage, serum creatinine (Cr), weight, BG and CHO, TGand 24-hour urinary protein quantitative were significantly higher in the DN rats than those in the normal control rats (P>0.05). The expression level of TGF-β1 and triglyceride level in the corn silk dihydroxycorn silk3 treated group were obviously lower than those in the DN rats.
