[Puerarin combined with avandia for diabetic nephropathy]

To observe the effect and mechanism of avandia and puerarin used in combination for diabetic nephropathy.

A total of 180 patients with diabetic nephropathy were randomly divided into 3 groups. The control group (58 patients, group A) were treated with routine therapy including controlling the blood glucose and blood pressure, while 60 patients in group B were treated by avandia besides routine treatment of the control group. Anoter 62 cases in group C were administered with puerarin combined with avandia for 12 weeks. The indexes such as urea nitrogen, serum creatinine, triglyceride, cholesterol, low density lipoprotein, high density lipoprotein, mean arterial pressure, fasting blood glucose, 2h plasma glucose, glycosylated hemoglobin, and 24 h urinary albumin excretion rate were tested before and after the treatment .

No significant differences were found in the indexes such as triglyceride, serum cholesterol, low density lipoprotein, high density lipoprotein, glycosylated hemoglobin, malonaldehyde, erythrocuprein, blood urea nitrogen, serum creatinine and 24 h urinary albumin excretion rate among the 3 groups (P>0.05). There were no significant differences in all indexes before and after the treatment in group A (P>0.05) . After the treatment, 24 h urinary albumin excretion, urea nitrogen, serum creatinine, mean arterial pressure, fasting blood glucose, 2 h plasma glucose, glycosylated hemoglobin, triglyceride, serum cholesterol, low density lipoprotein decreased significant (P<0 05) while high density lipoprotein increased significant (P<0.05).

Avandia has better effect on adjusting the blood lipid and decreasing the urinary albumin excretion rate. Puerarin combined with avandia is more effective for improving the renal function and remission of islet function than using avandia alone. Puerarin and avandia have significant synergism.
