the multi-center clinical study of tang shen prescription on type 2 diabetic kidney disease in early stage

Conditions: Diabetic Kidney Disease

Summary: this study is a randomized, double-blinded, placebo-controlled clinical trial on type 2 diabetic kidney disease in early stage ( microalbuminuria excretion rate = 20-200mg/min) to evaluate the therapeutic effect of tang shen prescription. 632 participants will be recruited for the study, all of whom had type 2 diabetes, serum creatinine concentrations is normal, and no evidence of non-diabetic renal diseases. the subjects will be randomized to treatment with either tang shen prescription or placebo.
