ABSTRACT
<p><b>OBJECTIVE</b>To make a study of the influence of the intervene of traditional Chinese medicine on cytokine level in benign prostatic hyperplasia.</p><p><b>METHOD</b>The patients were divided into treatment group (group A), control group (group B) and healthy group (group C) with the randomly compared researching method. Group A were given Qianliening Tang (QLNT), daily potion, two times a day. Group B were given Qianliekang, three times a day, three pills each time. The course of both treatment lasted for 8 weeks.</p><p><b>RESULT</b>Before treatment, TNF-alpha, IL-17/IL-10, IL-4 in group A and B are obviously out of order compared with group C (P < 0.01). After the treatment, TNF-alpha, IL-17 in group A decreased dramatically and IL-10, IL-4 increased, which shows great differences compared with those before treatment and with group B (P < 0.01), but still can't reach to group C level.</p><p><b>CONCLUSION</b>Qian liening Tang can efficiently regulate the level of suppressive inflammatory cytokines and proinflammatory cytokines. It provides scientific experimental basis for clinical diagnosis and treatment of the disease.</p>
