某部队男性官兵前列腺炎及其相关因素的调查研究

目的：了解部队男性官兵前列腺炎的发病情况及影响因素调查。方法：采用整群分层,随机抽样,对某高原部队300名男性官兵进行问卷调查,并对官兵的生殖系统、前列腺液等进行相关检查。结果：发现前列腺炎12人,多数为已婚的干部及入伍前有女朋友的战士。约66%官兵了解生殖健康概念及内容,与被调查者的学历、职务、是否来自城市等有关;对性传播疾病的病种及传播途径了解不够的官兵达20%。结论：部队官兵的生殖健康良好,少数有前列腺炎,最好定期进行生殖系统疾病筛查;部队官兵对生殖健康概念及内容了解尚可,但还应加强宣传教育。     

雌激素诱导SD大鼠前列腺炎与内环境改变的关系

目的 通过雌二醇诱导SD雄鼠慢性前列腺炎,探讨SD雄鼠的内环境改变的关联性作用,为前列腺炎发生机制和治疗提供一条实验性途径.方法 3%戊巴比妥麻醉,无菌条件下去势手术;术后动物恢复5 d,30只雄鼠按照体重随机分组,每组10只.第6天低剂量组皮下注射0.25 mg/kg的雌二醇,高剂量组皮下注射1.25 mg/kg的雌二醇,溶媒对照组注射橄榄油,每天1次,连续30 d.结果 与溶媒对照组比较,低、高剂量组白细胞（WBC）、红细胞（RBC）、血红蛋白（HGB）和红细胞压积（HCT）均降低（P〈0.01）;前列腺酸性磷酸酶（PAP）明显降低（P〈0.01）;高剂量组睾酮含量明显增加（P〈0.01）,C-反应蛋白（CRP）在低、高剂量组也呈现增加的趋势,但差异没有统计学意义;溶媒对照组和给药组前列腺组织大体解剖表面未见明显差异,光学显微镜下,溶媒对照组前列腺组织结构完整、腺腔和间质无炎性细胞浸润,高剂量组和低剂量组的前列腺间质均可见炎细胞浸润;低、高剂量组大鼠脾脏均可见棕黄色颗粒沉淀,其余脏器无明显改变,胸腺、脾脏及其脏器系数均明显降低.结论 根据本实验结果,雌激素引起的慢性非细菌性前列腺炎可导致内环境血液学、血清生化,激素水平、脏器和脏器系数的一系列改变.     

慢性前列腺炎厌氧菌感染的研究

本文对１０６例前列腺标本进行了细菌学研究。慢性前列腺炎厌氧菌检出率为２７．３％（２９／１０６）。厌氧菌阳性者中６８．９％（２０／２９）与需氧菌组成混合感染３１％（９／２９）为单纯厌氧菌感染。研究还提示：厌氧菌感染是慢性前列腺炎不可忽视的原因,氟呱酸对厌氧菌有强大杀灭作用。     

氟氏佐剂诱导大鼠慢性前列腺炎疼痛模型中L5-S2脊髓中枢小胶质细胞的活化

目的:观察大鼠慢性前列腺炎疼痛模型中L5-S2脊段背角小胶质细胞活化的变化.方法:通过前列腺完全弗氏佐剂注射制作大鼠慢性前列腺炎疼痛模型,对照组注射生理盐水,观察时间为0、4、12、24d,用热辐射痛阈测定法和前列腺病理进行疼痛模型鉴定,采用实时荧光定量RT-PCR检测L5-S2脊段后角中小胶质细胞标志物IBA-1的表达.结果:成功建立慢性前列腺炎疼痛大鼠模型,并观察到L5-S2脊髓背角中存在小胶质细胞的活化.结论:慢性前列腺炎疼痛可以引起L5-S2脊髓中枢小胶质细胞活化,小胶质细胞异常活化可引起神经炎性疼痛,有可能与慢性前列腺炎疼痛的持续和泛化有密切关系.     

Ⅱ型前列腺炎患者前列腺结石与临床症状相关性分析

目的:讨论Ⅱ型前列腺炎患者前列腺结石、前列腺液白细胞数及临床症状相关性.方法:我院门诊2009年1月至2011年12月就诊的327例Ⅱ型前列腺炎患者纳入研究.所有患者治疗前均行前列腺液白细胞计数、经腹前列腺彩超和慢性前列腺炎症状指数评分(CPSI),将结果进行统计学分析.结果:所有Ⅱ型前列腺炎患者的前列腺结石直径和前列腺液中白细胞计数两者有相关性,差异具有统计学意义(P＜0.05),前列腺结石直径和NIH-CPSI评分、前列腺液白细胞计数和NIH-CPSI评分均无相关性(P＞0.05).根据前列腺结石直径将患者进行分组,不同组别的患者的前列腺液白细胞计数不同,其差异有统计学意义(P＜0.05),NIH-CPSI评分组间差异无统计学意义(P＞o.05).结论:Ⅱ型前列腺炎患者就诊时前列腺结石、前列腺液白细胞计数和前列腺炎患者临床症状无明细相关性,因此Ⅱ型前列腺炎患者前列腺结石情况和前列腺液白细胞计数一样不能作为独立因素评估前列腺炎的临床症状的严重性并用于指导治疗.     

Influence of sexual intercourse on genital tract microbiota in infertile couples

Several studies have suggested the association of disturbed genital tract microbiota with infertility. Our aim was to clarify the influence of sexual intercourse on partner’s genital tract microbiota in infertile couples. Seventeen couples were studied, and in 5 men inflammatory prostatitis (IP) was diagnosed. Semen samples were collected during menstruation of the female counterpart, two self-collected vaginal samples were taken 3–5 days later – before intercourse and 8–12 h after intercourse. Ureaplasma parvum was found in 59% of women, its prevalence was higher in women whose partner had IP, as well as in half of their male partners. Sexual intercourse caused significant shifts in vaginal microbiota – increase of Nugent score and shifts in cultured microbiota (emergence and disappearance of several species). These changes were less expressed in the presence of normal vaginal microbiota but more prominent in the partners of IP men. These changes may interfere with fertilization.     

Tissue inhibitor of metalloproteinase-2 (TIMP-2) location in the ventral, lateral, dorsal and anterior lobes of rat prostate by immunohistochemistry

Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) play a major role in extracellular matrix component degradation in several normal and abnormal tissue situations; they are also found in human seminal plasma. MMPs have been found in rat prostate secretions and are nearly lobe specific in expression pattern. The aim of this study was to evaluate whether TIMP-2, like other semen components, is expressed differently from different rat prostatic lobes. Immunohistochemical staining was performed in both young and adult rat ventral (VP), lateral (LP), dorsal (DP), and anterior (AP) prostatic lobes and confirmed by western blotting. TIMP-2 expression was found in the epithelial cells in the following sequence: LP>AP>DP>VP, in both young and adult rats. In this study, 100% of adult LP presented histological signs of prostatitis, where TIMP-2 immunostaining was positive in normal epithelium even with intraluminal neutrophils, but was reduced or absent in the epithelium with intraepithelial leukocytes or with periductal stroma disorganization associated with mononuclear cell infiltration. However, TIMP-2 expression in LP was not induced by prostatitis, since younger rat LPs were also strongly TIMP-2 positive. The distal and intermediate VP regions were TIMP-2 negative, but the proximal regions were strongly stained. Western blotting results confirmed the high TIMP-2 expression in the LP lobe. Thus, TIMP-2 is expressed differently between the prostatic lobes and is another nearly lobe-specific protein, which plays a role in the regulation of MMP activity in seminal plasma and glandular homeostasis. TIMP-2 is also another regional ductal variation of VP. Further studies should address whether TIMP-2 expression is related to the highest incidence of rat LP prostatitis and adenocarcinoma.     

252例前列腺炎患者前列腺液细菌培养及药敏试验结果

目的了解本地区细菌性前列腺炎患者感染的病原菌种类及耐药情况,为临床治疗提供依据。方法对252例细菌性前列腺炎患者的前列腺液作细菌培养,用美国德灵公司MicroScan Auto SCAN4型细菌鉴定仪及药敏分析仪对分离的细菌进行鉴定及药敏试验。结果252例标本中,阳性154例,阳性率61．1％,以金黄色葡萄球菌为主,其次为大肠埃希菌和表皮葡萄球菌。药敏试验结果显示,常规使用的抗生素如青霉素G、氨苄西林、复方新诺明、环丙沙星等耐药率较高,在61．3％-83．9％,而对万古霉素、亚胺培南、阿米卡星、妥布霉素、利福平、左旋氧氟沙星等敏感性较高。结论细菌性前列腺炎患者的治疗,应以细菌培养及药敏试验结果为依据,指导临床合理选用抗菌药物。     

慢性前列腺炎及其不育患者前列腺液的厌氧菌研究

本文报告95例(24～40岁)慢性前列腺炎(Chronic ProstatitisCP)患者前列腺液(简称EPS)的厌氧菌培养结果。厌氧菌培养阳性49例(51.57％),共分离出26种65株厌氧菌,分离率从高至低依次为拟杆菌(41.65％),消化链球菌(29.23％)、消化球菌(9.23％)和小韦荣氏球菌(4.62％),还有梭杆菌、衣氏放线菌、丙酸杆菌和真杆菌。这些厌氧菌种类与男性尿道口和女性生殖道正常菌群的厌氧菌相似,提示这些厌氧菌是泌尿生殖道正常菌群,也可能是条件致病菌。对照组(24～38岁)的正常男性15例的EPS厌氧菌培养均阴性。对上述CP患者中的69例生育力与厌氧菌培养阳性率比较,对照组15例,CP患者生育组34例和不育组35例,三个组之间患者EPS的厌氧菌阳性率经统计学处理有非常显著性差异(P<0.01)、CP不育组与对照组有非常显著性差异(P<0.01),而CP生育组与对照组无显著性差异(P>0.05)。提示厌氧菌可能不仅是慢性前列腺炎的致病菌之一,而且可能还与慢性前列腺炎所致的不育有关。
