RESUMO
The aim of this study is to assess the status of treatment of chronic prostatitis (CP) in Chinese men. A population-based cross-sectional survey was performed, in which 15 000 men aged between 15 and 60 years were randomly selected to receive a questionnaire designed to assess National Institutes of Health Chronic Prostatitis Symptoms Index (NIH-CPSI) status, therapeutic efficacy and 28 other items. A total of 12 743 men (84.95%) completed the questionnaire, of whom 1 071 (8.4%) were identified as having prostatitis-like symptoms and 517 (4.5%) were diagnosed with CP according to NIH-CPSI criteria and prostatitis-like symptomatology. Of the CP patients, 372 (65%) underwent long-term routine treatment 12 times per year. Additionally, 217 (72.8%) patients received antibiotic therapy and 215 (79.3%) men showed therapeutic effects. The treatment cost USD 1 151 (8 059 yuan) per person per year on average. Most CP patients received routine treatment, in most cases with antibiotics. Treatment was costly and most CP patients were not satisfied with its effectiveness. Antibacterial treatment might have been effective primarily in patients with bacterial disease.

<p><b>OBJECTIVE</b>To investigate the regulatory effect of potassium channel blocker (tetraethylammonium [TEA], aminopyridine [4-AP], glibenclamide [Glib]) on the proliferation of SD rat prostatic epithelial cells in vitro.</p><p><b>METHODS</b>The primary culture was prepared by collagenase dissociation of minced prostatic tissues. Cells were cultured in serum-free prostate epithelial cell growth media and identified by immunocytochemical studies. TEA and 4-AP at the concentration of 1, 5 and 10 mmol/L and Glib at the concentration of 10, 50 and 100 mol/L were added, and after 24, 48 and 72 hours of culturing, a cell column diagram was drawn and the cell number counted. The post-passage cell growth was observed by MTT assay and Hoechst33258 nucleus staining.</p><p><b>RESULTS</b>The cultured cells showed the typical morphological features of epithelia, with positive stain. MTT assay and Hoechst33258 staining showed that TEA, 4-AP and Glib at the increasing concentration effected different degrees of proliferation of prostatic epithelial cells after 24, 48 and 72 h (P < 0.01).</p><p><b>CONCLUSION</b>The potassium channel blocker is a direct physiological regulator of the proliferation of SD rat prostatic epithelial cells.</p>
