[Clinical observation on treatment of early diabetic nephropathy by milkvetch injection combined with captopril].

OBJECTIVE: To investigate the therapeutic effect of milkvetch injection (MI) combined with Captopril on early diabetic nephropathy (EDN). METHODS: A total of 69 EDN patients were randomly divided into three groups, with 23 in each group. Besides the conventional hypoglycemic therapy, patients in Group A Captopril, in Group B MI plus Captopril and in Group C MI were given respectively. The therapeutic course for all was 3 months. The related indices of EDN before and after treatment were measured and compared. RESULTS: After treatment, the blood pressure significantly lowered after treatment in Group A and B (P<0.01), but unchanged in Group C; the levels of blood glucose and HbA1c significantly decreased in Group B and C (P < 0.05 or P<0.01), and significant difference was shown in comparison of Group B with Group A (P<0.05); levels of 24hrs urinary albumin excretion (UAER), blood urea nitrogen (BUN) and serum creatinine (SCr) significantly decreased in all 3 groups, and the decrement in Group B was more significant than that in the other two groups (P <0.05). CONCLUSION: MI combined with Captopril can not only decrease blood pressure, blood glucose and HbA1c, but also significantly decrease the UAER in treating EDN.
