摘  要:目的:探讨神经生长因子( nerve growth factor , NGF )、转化生长因子( transforming growth factor ,TGF)-β1、雌二醇、睾酮在Ⅲ型前列腺炎[慢性前列腺炎/慢性骨盆疼痛综合征( chronic prostatitis/chronic pelvic pain syndrome,CP/CPPS)]患者血清和前列腺液(expressed prostatic secretion, EPS)中的表达水平及意义。方法随机收集2011年8月至2012年1月收治的CP/CPPS患者64例和健康对照者20例。 CP/CPPS组患者年龄18~56岁,平均(36.6±9.3)岁;病程3个月~6年,平均2年;均行前列腺炎症状指数(NIH-CPSI)评分,其中ⅢA组35例,ⅢB组29例。健康对照组年龄25~41岁,平均(33.1±3.9)岁。应用放射免疫法和酶联免疫吸附法检测所有受试者血清和EPS中雌二醇、睾酮、NGF、TGF -β1的表达水平。比较各组血清和EPS 中雌二醇、睾酮、雌二醇/睾酮比值、NGF、TGF-β1水平的差异,分析CP/CPPS患者上述指标与前列腺炎症状的关系。结果 CP/CPPS组血清雌二醇(175.7±82.4)pmol/L、雌二醇/睾酮(7.9±6.7)、TGF-β1(2216.2±581.6)ng/L高于对照组的(131.7±49.4)pmol/L、(4.6±2.4)、(1599.8±469.5)ng/L,而睾酮(24.7±8.9)nmol/L低于对照组的(29.2±7.0)nmol/L;EPS 中雌二醇/睾酮(34.5±29.8)、TGF-β1(6859.3±5229.4) ng/L、NGF(467.0±164.3)ng/L高于对照组的(16.5±13.8)、(1774.1±1304.3)ng/L、(310.8±106.6)ng/L,差异均有统计学意义(P<0.05)。 CP/CPPS组尿路症状评分(6.1±2.4)分,与EPS中TGF-β1水平呈正相关(r=0.641, P<0.05),疼痛症状评分(7.6±2.4)分与EPS中NGF水平呈正相关(r=0.497,P<0.05)。ⅢA组血清雌二醇/睾酮(7.1±4.6)、TGF-β1(2131.5±412.0) ng/L 和 EPS 中雌二醇/睾酮(31.5±22.3)、TGF-β1(7667.1±5652.4)ng/L、NGF(440.6±134.3)ng/L均高Objective To investigate the level and clinical significance of nerve growth factor ( NGF) , transforming growth factor ( TGF )-β1 , estradiol ( E2 ) and testosterone ( T ) in serum and ex-pressed prostatic secretion (EPS) of patients with category Ⅲprostatitis. Methods From August 2011 to January 2012, 64 patients with (chronic prostatitis/chronic pelvic pain syndrome , CP/CPPS) and 20 health people were enrolled in this study.In CP/CPPS group, the age of patients ranged from 18 to 56 years, mean (36.6±9.3) years.The history of CP/CPPS ranged from 3 months to 6 years, mean 2 years.All patients were asked to complete NIH-CPSI questionnaires with CP/CPPS, including group ⅢA 35 cases and groupⅢB 29 cases.The age of healthy controls ranged from 25 to 41 years.The average healthy control age was (33.1±3.9) years.EPS and serum samples from CP/CPPS and control group were collected and frozen . NGF, TGF-β1 , E2 and T level in EPS and serum were measured by ELISA and radioimmunoassay and com -pared in each group. Results The mean E2, E2/T, TGF-β1 level in serum of patients with CP/CPPS were (175.7±82.4) pmol/L, (7.9±6.7), (2 216.2±581.6) ng/L, which were higher than that in healthy controls, (131.7±49.4) pmol/L, (4.6±2.4), (1 599.8±469.5) ng/L.The mean T level in CP/CPPS pa-tients′serum was (24.7±8.9) nmol/L, which was lower than that in controls (29.2±7.0) nmol/L.The E2/T (34.5±29.8), TGF-β1(6 859.3±5 229.4 ng/L), NGF (467.0±164.3 ng/L) levels in EPS of CP/CPPS patients were higher than that in controls (16.5±13.8), (1 774.1±1 304.3) ng/L, (310.8±106.6) ng/L. The TGF-β1 level in EPS of CP/CPPS patients showed the positive correlation ship with urination symptom score (6.1±2.4) (r=0.641, P〈0.05).The NGF level in EPS of CP/CPPS patients also showed the positive correlation ship with pain score (7.6±2.6) (r=0.497, P〈0.05).E2/T,TGF-β1 levels in serum and E2/T, TGF-β1,NGF levels in EPS
