Abstract： Objective To evaluate the effect of the Danhong injection combined with irbesartan in treatment ofearly diabetic nephropathy. Methods 64 patients with early diabetic nephropathy were randomly divided into two groups and the control group 32 cases,two groups were given control of blood sugar and ensure water and electrolyte balance,support therapy,in which 32 cases were also observed red Danhong injection,Ecuador irbesartan treatment,2weeks before evaluation. Results The total effective rate in treatment group was higher than the control group( x2 =6.38 ,P ＜0. 05) ,after 12 weeks of treatment,two groups of urinary protein decreased significantly compared with before treatment, including observation of urine protein was ( 0. 6± 0. 1 ) g/24h, the control group was ( 0. 7 ± 0. 3 ) g/24h,and decreased urine protein level of the observation group was better than the control group( t = 2. 74,P ＜ 0. 05 ). And in the course of treatment, side effects and serious adverse events were not found.
