男男性行为者商业性性行为特征研究

目的了解深圳市男男性行为者（MSM）中男性性工作者（MSW）商业性性行为的特征,为制定艾滋病（AIDS）防治策略提供依据。方法对深圳市548名MSM进行问卷调查和病毒抗体检测。结果调查的548名MSM中,24.3%（134/548）的人在近6个月内发生过商业性性行为,其中仅向男性提供商业性性行为和为两性均提供商业性性行为的分别占46.3%和53.0%。近1月每人每次收费男性和女性分别平均为633元和873元,女性收费高于男性（P〈0.01）。不同性别客人以及MSW对不同性别客人使用安全套的态度不同。近1月和近6月性服务人数,最近一次使用安全套情况不同性别客人差异无统计学意义。134名MSW的HIV、梅毒、丙肝抗体阳性分别是12.0%、9.8%和1.5%。结论 MSW有较大程度传播HIV的危险,应加强对这一人群的AIDS知识健康教育。     

Underweight and overweight men have greater exercise-induced dyspnoea than normal weight men

Abstract

Introduction. Persons with high or low body mass index (BMI), involved in clinical or mechanistic trials involving exercise testing, might estimate dyspnoea differently from persons with a normal BMI.

Aims. Our objective was to investigate the relationship between BMI and dyspnoea during exercise in normal subjects with varying BMI.

Material and methods. A total of 37 subjects undertook progressive exercise testing. Subjects were divided into three groups: underweight (UW), normal weight (NW), and overweight (OW). Dyspnoea was estimated using the visual analogue scale (VAS). Spirometry, maximum voluntary ventilation (MVV), and respiratory muscle strength (RMS) were measured.

Results and discussion. The intercept of the VAS/ventilation relationship was significantly higher in NW subjects compared to UW (P = 0.029) and OW subjects (P = 0.040). Relative to the OW group, FVC (P = 0.020), FEV₁ (P = 0.024), MVV (P = 0.019), and RMS (P = 0.003) were significantly decreased in the UW group. The greater levels of dyspnoea in UW subjects could possibly be due to decreased RMS. Healthy persons should aim to achieve an optimum BMI range to have the lowest exercise-induced dyspnoea.

The greater levels of dyspnoea in UW subjects could possibly be due to decreased RMS. Healthy persons should aim to achieve an optimum BMI range to have the lowest exercise-induced dyspnoea.     

与同性发生性行为的男性溃疡性直肠炎：一种新出现的疾病

性病性淋巴结肉芽肿（LGV）为L1、L2和L3型沙眼衣原体所导致的一种性传播感染性疾病。尽管该病在一些热带国家为地方病，但在英国，性病性淋巴结肉芽肿通常较为罕见。LCV的典型表现为生殖器溃疡（其可无症状或仅短暂出现）及相关的痛性腹股沟淋巴结病变（或腹股沟淋巴结炎），不过其也可表现为直肠炎．生殖器外的淋巴结病变及发热等全身症状。     

Hemoglobin values in aged men

To determine whether the level of hemoglobin declines with age a group of 92 aged males averaging 81 years was carefully examined to exclude disease likely to cause anemia or polycythemia. Arterial blood was drawn from each patient before he was allowed out of bed in the morning to avoid the hemoconcentrating effect of the erect posture. The mean hemoglobin concentration was 12.9 ± 1.5 g.% and the values were distributed normally. There was a decline of hemoglobin concentration with age which is probably nonlinear since it becomes more marked in the very old. The decline is thought to be part of the aging process and not a manifestation of disease.     

434名男男性行为者艾滋病知识和行为调查

目的了解芜湖市男男性行为者（MSM）艾滋病相关知识知晓率、性行为学特征及其影响因素,为开展有效干预措施提供依据。方法采用分类滚雪球的抽样方法对MSM进行匿名问卷调查。结果共对434名男同性恋者进行了调查,艾滋病相关知识知晓率为80．4％。经Logistic回归分析发现,寻找性伴的场所档次和文化程度越高,其知晓率越高,年龄越高知晓率越低。最近6个月所有MSM均与同性发生过性行为,36．9％与同性发生性行为时每次都使用安全套。最近6个月,10．8％的调查对象与同性发生过商业性性行为,25．1％的调查对象与异性发生过性行为。样本来源、艾滋病知识知晓率、是否进行过性病诊疗和最近1年是否做过AIDS检测对最近6个月MSM性行为时每次都用安全套有影响。结论在MSM中存在知识与行为脱离现象,应针对不同年龄组的MSM采取不同的干预措施。     

南京市秦淮区场所型男男性行为人群干预模式探讨

目的探索在MSM娱乐场所集中地区开展艾滋病高危行为干预工作的模式。方法2008～2011年间,依靠政府的支持．通过场所员工组成的同伴宣传员队伍广泛深入开展宣传教育,区CDC在场所建立咨询检测受点提供便捷服务,同时与医疗机构及感染者关怀小组合作,积极开展针对MSM人群的各项工作。结果该人群具有HIV高感染率（9．5％。12．86％）、高知晓率（94．53％～94．82％）、行为高风险的特点。同时,建立了政府支持,充分发挥同伴宣传员作用、疾控中心提供技术服务,医疗机构社会小组支持的干预模式。结论该干预模式在MSM场所早期发现病例、阻止艾滋病进一步扩散方面起了很大的作用。
