RESUMO
<p><b>OBJECTIVE</b>To study the clinical effects of the modified formula of Bazhengsan on the urination symptoms of chronic prostatis with damp-heat accumulated in the lower jiao.</p><p><b>METHODS</b>A total of 72 chronic prostatitis patients with damp-heat accumulated in the lower jiao were equally randomized to receive the modified formula of Bazhengsan (the trial group) and the primal Bazhengsan (the control group), both for a course of 28 days. Then we observed the changes in the NIH-CPSI scores, scores on Traditional Chinese Medicine (TCM) syndrome, maximum flow rate of urine (MFR) and results of the expressed prostatic secretion test (EPS).</p><p><b>RESULTS</b>Among the 31 patients of the trial group, 6 were cured, 10 achieved excellent results, 9 got improved, and 6 failed to respond, with a total efficacy rate of 80.6%. While in the control group, 4 were cured, 10 achieved excellent results, 11 got improved, and 7 failed to respond, with a total efficacy rate of 78.1%. Significant improvement was observed in NIH-CPSI scores, TCM syndrome and EPS results in both of the groups (P < 0.05), and the trial group showed significant difference from the control in the improvement of urination symptoms (P < 0.05).</p><p><b>CONCLUSION</b>Modified Bazhengsan is effective in the treatment of chronic prostatis with damp-heat in the lower jiao. It can significantly improve its clinical symptoms, especially urination symptoms.</p>
