[摘要] 目的：探讨前列腺按摩液(EPS)中细胞因子白细胞介素-8(IL-8)及肿瘤坏死因子-α(TNF-α)在Ⅲ型前列腺炎[慢性非细菌性前列腺炎/慢性盆底疼痛综合征(CAP/CPPS)]诊断、分型中的意义。方法：ELISA法检测50例临床诊断为Ⅲ型前列腺炎患者EPS中IL-8及TNF-α水平。结果：慢性非细菌性前列腺炎EPS中ⅢA型组TNF-α水平与ⅢB型组、对照组比较，有显著性差异(P<0.05)；ⅢB型组TNF-α水平与对照组比较，无显著性差异(P>0.05)。ⅢA型组IL-8水平与ⅢB型组、对照组比较，有非常显著性差异(P<0.01)；ⅢB型组与对照组比较，有非常显著性差异(P<0.01)。所有患者EPS中TNF-α水平与WBC计数无明显相关性(r=-0.167，P>0.05)，IL-8水平与WBC计数的相关性分析显示呈正相关(r=0.836，P<0.01)。结论：检测Ⅲ型前列腺炎患者EPS中IL-8及TNF-α水平可能有助于Ⅲ型前列腺炎的分型诊断，并可作为了解病情和评价治疗效果的一个有价值的指标。

[Abstract] Objective: To investigate the significance of interleukin-8 (IL-8) and tumor necrosis factor-α (TNF-α) in expressed prostatic secretion (EPS) for diagnosis and classification of prostatitis Ⅲ [chronic nonbacterial prostatitis/chronic pelvic pain syndrome (CPPS)]. Methods: IL-8 and TNF-α in EPS of 50 patients with prostatitis Ⅲ were detected by ELISA. Results: The level of TNF-α in EPS of patients with chronic nonbacterial prostatitis group ⅢA was significantly different with group ⅢB and the control group (P<0.05). Level of TNF-α had no statistical significance between group ⅢB and the control group (P>0.05). Level of IL-8 in group ⅢA had very significant difference compared with group ⅢB and the control group (P<0.01);compared with the control group, IL-8 in group ⅢB had a very significant difference (P<0.01). TNF-α level in EPS of all patients had no significant correlation with WBC count (r=-0.167, P>0.05), IL-8 level and WBC count showed a positive correlation by the correlation analysis (r=0.836, P<0.01). Conclusion: The detection of IL-8 and TNF-α levels in patients with prostatitis may contribute to diagnosis and classification of prostatitis Ⅲ as the valuable indicators to understand the state of an illness and evaluate the effect of treatment ......
