A Prospective, Open, Multicenter, Clinical Study of Huangqi Guizhi Wuwu Decoction in Treating Diabetic Nephropathy (Stage CKD2-4)

This is a prospective, open, multicenter clinical trial.The objective of this study is to evaluate the efficacy and safety of Huangqi Guizhi Wuwu Decoction in patients with CKD stage 2-4 diabetic nephropathy.

The incidence rate of chronic kidney disease is 10.8% in China. The incidence rate of diabetic nephropathy has increased year by year, and now it has become the first cause of uremia. Therefore, the treatment of diabetic nephropathy can delay the progression of renal function and is of great value and significance in reducing uremia. Huangqi Guizhi Wuwu decoction is a traditional Chinese medicine decoction. Previous studies have shown that it is effective in the treatment of diabetic nephropathy. In this study, there were 2 hospitals participating in.
