ABSTRACT
<p><b>OBJECTIVE</b>To study the therapeutic effect of traditional Chinese herbal medicinal preparation Tangshenqing (TSQ) combined with alprostadil in the treatment of early- and intermediate-stage diabetic nephropathy (DN).</p><p><b>METHODS</b>One hundred and twenty DN patients were randomized into 3 groups for different treatment protocols. The patients in the control group were given the basic treatment (low-protein diabetic diet and rigorous control of blood glucose, blood pressure, and blood fatty acid), and those in treatment group A received TSQ (containing Astragalus membranaceus, Panax notoginseng, Epimedium brevicornum, etc) in addition to the basic treatment, and those in treatment group B were treated with alprostadil injections (for 14 consecutive days) in addition to the treatment given in group A. Therapeutic effect evaluation was carried out after a 30-day treatment in all the patients.</p><p><b>RESULTS</b>The overall efficaey rate of the treatment was 78.37% in the control group, 88.57% in the treatment group A, and 94.44% in treatment group B, suggesting better therapeutic effect in the latter two groups than in the control group (P<0.05). Patients in all the 3 groups exhibited symptomatic improvement of various degrees, but the treatment group B had the best results. After the treatments, the patients' blood glucose and fatty acids were lowered, without obvious difference between the 3 groups. Compared with the control group, the patients in the two treatment groups showed significant reduction in fibrinogen, 24-h urine microprotein and urine protein after the treatment (P<0.01 or 0.05).</p><p><b>CONCLUSION</b>Combined use of traditional Chinese herbal medicine TSQ and alprostadil injections produces definite therapeutic effect on early- to intermediate-stage DN.</p>
