简介：我们比较了与长期的前列腺炎症候群(每秒字符数)联系的棒状细菌细菌的潜在的phenotypic性质，例如溶解酵素(SIL)的能分泌的禁止者和血小板microbicidal蛋白质(SIPMP)的能分泌的禁止者。一个总数110临床棒状细菌孤立与每秒字符数从健康的人和人的精液孤立的细菌被测试。SIPMP生产被禁止血小板microbicidal测试对杆菌subtilis的蛋白质(PMP)bioactivity，并且被表示为PMP的抑制的百分比杀菌活动。SIL生产被对小球菌lysodeikticus禁止溶解酵素活动测试并且每使失去活性的溶解酵素的毫升在microgram被表示。每秒字符数紧张(58.7%对19.2%)的一个显著地更高的比例与非每秒字符数紧张相比是SIPMP积极的(P<0.01)。测试的CPS紧张，77.8%与34%非每秒字符数相比是SIL积极的孤立(P<0.05)。这些结果建议例如，每秒字符数的诊断不应该完全依靠古典参数鉴定并且微生物，而是这些参数的功能的意义数必须被估计，可能由不同细菌的substrains的集中，有病原的性质的机会主义的微生物的察觉，例如到cationic抗菌剂的显著抵抗，禁止抗菌剂的肽，或能力招待防卫因素。

简介：这研究试图决定血浆睾丸激素是否在经历了选任的冠的angiography的一组803个人与冠的动脉粥样硬化的严厉被联系。睾丸激素层次在根据睾丸激素水平tertiles被分成三个组的803个男病人被测量。所有病人经历了选任的冠的angiography，并且冠的动脉疾病(CAD)的严厉被Gensini分数决定。而且，病人们根据Gensini分数被分类进二个组(20≤；26和20>；26)用是的中部的价值，截止指。血浆睾丸激素层次被一个ELISA工具包测量。睾丸激素的水平否定地与Gensini分数被联系(r=−；0.188；P=0.000)。多重线性回归分析表明那睾丸激素是为Gensini分数的一个独立风险因素(β；=−；0.110；P=0.002)在为使covariates惊讶调整以后。在multivariate逻辑回归模型，CAD的严厉被显示在第三tertile显著地更低(最高)与第一tertile相比的睾丸激素(最低)睾丸激素(机会比率(或)=0.465；95%；信心间隔(CI)：0.327-0.662；P=0.000)。在这研究，有更低的睾丸激素层次的病人在经历了选任的冠的angiography的一组803个人有更高的Gensini分数。另外的研究被需要澄清诱发性和可能的位于\O下面机制的方向。

简介：AbstractBackground:Sexual transmission among men who have sex with men (MSM) is the dominant route of HIV transmission in China. Extensive use of geosocial networking (GSN) smartphone application (app) has dramatically changed the pattern of sexual behaviors and HIV risk among MSM, but data on HIV incidence and the changing risk behaviors of GSN app-using MSM are limited. We aims to assess the HIV incidence and its correlates among gay GSN app-using MSM in China.Methods:We constructed an open cohort which was initiated and maintained using a GSN app to assess the HIV incidence among app-using MSM, recruited from June 2017 to December 2018. MSM completed an online questionnaire on their sociodemographic characteristics, sexual behaviors, recreational drug use and sexually transmitted infections status. Then each man had an HIV test, and those tested negatives were enrolled into the cohort. Participants completed follow-ups with additional HIV tests though the app during the study period, and were censored at HIV seroconversion or study end date. HIV incidence was calculated by dividing the sum of observed HIV seroconversions by the observed person-time. Univariate (Chi-square test and Fisher’s exact test) and multivariate (proportional hazards regression) analyses were used to examine correlates of HIV incidence.Results:A total of 6957 HIV negative MSM were enrolled in the open cohort, 37 seroconversions occurred among 1937 men contributing 1065 observed person-years: HIV incidence was 3.47 per 100 person-years [95% confidence interval (CI): 2.37-4.57]. More than five sexual partners [hazard ratio (HR) = 2.65, 95% CI: 1.04-6.67], and sex with HIV positive partners (HR = 3.82, 95% CI: 1.16-12.64) in the preceding six months were positively associated with HIV seroconversion. Consistent condom use for anal sex (HR = 0.27, 95% CI: 0.07-0.96), and reporting insertive anal sex only (HR = 0.23, 95% CI: 0.08-0.62) in the preceding six months were protective factors for HIV seroconversion.Conclusions:Tailored interventions targeting app-using MSM are urgently needed given their high risk of HIV. As a new tool for accessing MSM at higher HIV risk, GSN smartphone app could play an important role in HIV research among MSM.
