Intracellular calcium ion concentration in the prostate smooth muscle cells of chronic abacterial prostatitis rat models and normal controls / 中华男科学杂志

<p><b>OBJECTIVE</b>To investigate the difference in intracellular calcium ion [Ca2+]i concentration in prostate smooth muscle cells (PSMCs) between SD rat models of chronic abacterial prostatitis (CAP) and normal controls, and to evaluate the role of [Ca2+]i concentration in CAP.</p><p><b>METHODS</b>We established CAP models in SD rats using purified prostate protein and Freund's complete adjuvant, cultured in vitro and then purified the PSMCs of both the CAP models and normal controls. Continuous dynamic scanning was performed under the laser confocal scanning microscope after incubation of the cells with FLUO-3AM.</p><p><b>RESULTS</b>The fluorescence intensities of [Ca2+]i in the PSMCs were 80.39 +/- 9.00 and 27.95 +/- 10.04 in the CAP models and normal controls, respectively, with statistically significant differences between the two groups (P < 0.01).</p><p><b>CONCLUSION</b>The concentration of [Ca2+]i increased in the PSMCs of the CAP rat models, which might enhance the constriction of PSMCs and subsequently increase the sensibility to pain and cause lower abdominal pain.</p>

Treatment of chronic prostatitis in Chinese men / 亚洲男科学杂志(英文版)

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.
