Prevalence and risk factors associated with HIV infection among female sex workers in Mengzi City

目的了解云南省蒙自市女性性工作者(FSWs)艾滋病病毒(HIV)的感染情况及HIV感染相关危险因素,为制定艾滋病防控策略和行为干预提供依据。方法于2010年10-11月采用方便抽样的方法,招募云南省红河州蒙自市娱乐场所FSWs,调查其社会人口统计学、行为学、HIV/AIDS知识以及生殖健康状况,并采集静脉血进行HIV血清学检测,分析FSWs人群HIV感染率及其危险因素。结果本次共调查423名FSW,HIV抗体阳性19人,HIV抗体阳性率为4.5%。最近一个月与客人发生性行为时坚持使用安全套的比例为87.0%。多因素分析显示,与HIV感染相关的危险因素为在低档性服务场所服务(校正OR=10.0,95%CI:3.77~26.67,P<0.001)和从事性服务时间≥2年(校正OR=3.8,95%CI:1.39~10.20,P=0.01)。结论蒙自市FSWs有较高的HIV感染率,在低档性服务场所服务及从事性服务时间长是HIV感染的危险因素,需针对低档和中高档FSWs的危险行为特征分别实施不同的干预措施,控制HIV的传播流行。Objective To explore the prevalence and risk factors of HIV infection among female sex workers( FSWs) in Mengzi City,Yunnan Province,so as to provide scientific evidence for formulating HIV prevention and control strategy and behavior intervention measures. Methods From October to November,2010,the convenience sampling method was used to recruit FSWs in the entertainment venues in Mengzi City in Yunnan Province to investigate their demographic information,sexual behavior,HIV / AIDS knowledge and reproductive health status. Venous blood was collected to test HIV. The prevalence and risk factors of HIV infection were analyzed. Results Totally,423 FSWs were recruited,among whom 19 were confirmed to be HIV antibody positive and the prevalence rate of HIV was 4. 5%. The proportion of the FSWs with consistent condom use when having sex with clients in the last month was 87. 0%. Multivariate logistic analysis indicated that the factors associated with HIV infection were working in low level sex work venues( adjusted OR = 10. 0,95% CI: 3. 77-26. 67,P < 0. 001) and time engaged in sexual work for 2 years or more( adjusted OR = 3. 8,95% CI: 1. 39-10. 20,P = 0. 01). Conclusions The prevalence of HIV is high among female sex workers in Mengzi City. FSWs who work in low-grade sex work venues and engage in sexual work for long time are at higher risk of HIV infection. Intervention measures targeted at dangerous behavior of FSWs working in different levels of sex work venues should be carried out to control the spread and prevalence of HIV / AIDS.国家“十一五”重大专项(2008ZX10001-003

多重荧光PCR同时检测转基因成分35S和Nos方法的建立

根据商品化转基因作物中常用的花椰菜花叶病毒启动子 (CaMV 35S)和根癌农杆菌终止子 (Nos)的序列特点 ,设计并合成了两对引物和相对应的荧光双链探针 ,建立一种应用荧光双链探针的多重荧光PCR同时检测转基因成分 35S启动子和Nos终止子的方法 .并利用该方法对马铃薯、大豆、玉米、甜椒、番茄等 11份实物样品进行了检测 ,其中有 5份样品结果阳性 .结果表明所建立的多重荧光PCR方法能同时检测出 35S和Nos双组分 ,较常规PCR技术更为简便、快速、准确 ,有很好的应用前景

膜技术处理赖氨酸生产废水的研究

为了确定赖氨酸生产废水经过膜技术处理后废水中的CODcr值的大小 ,我们采用超滤与纳滤相结合的工艺分别对浓废水和稀废水进行中试实验。实验结果表明 :采用超滤 -一级纳滤 -二级纳滤工艺流程处理浓废水 ,终端废水的CODcr值降低到 489mg/L ;采用超滤 -纳滤流程处理稀废水 ,最终透析液的CODcr值可以降低到 5 0 2mg/L。大大减轻了后续生化处理的负荷

Isolation and structure elucidation of lipophilic cytotoxic compounds produced by a marine actinomycetes, N350

海洋微生物是当前抗肿瘤药物开发的重要新资源.应用硅胶柱层析结合活性跟踪分离的方法,从海洋放线菌菌株N350的脂溶性发酵产物中纯化并鉴定了4个化合物,分别为反式-13-二十二碳单烯酰胺,7,4'-二羟基异黄酮、6-甲氧基-7,4'-二羟基异黄酮及β-胡萝卜甙.其中,反式-13-二十二碳单烯酰胺、7,4'-二羟基异黄酮及6-甲氧基-7,4'-二羟基异黄酮具有抗肿瘤活性,抑制人口腔上皮癌KB细胞生长的ID50分别为15,8 1,5 2μg/cm3,抑制人白血病细胞HL-60生长的ID50分别为7,2 8,1 9μg/cm3.这些化合物均首次在海洋放线菌中得到分离.Marine microorganism, which can be easily reproduced in large scale in industry, is being exploited for new antitumor drugs with unique structure and excellent bioactivity. Four lipophilic cytotoxic compounds produced by a marine actinomycetes, strain N350, were purified by bioassay-guided isolation, and identified as cis-13-docosenmamide, 7, 4′-dihydroxyisoflavone, 6-methoxy-7, 4′-dihydroxyisoflavone, and β-sitosterol-β-D-glucopyranoside, respectively. Cis-13-docosenamide, 7, 4′-dihydroxyisoflavone and 6-methoxy-7, 4′-dihydroxyisoflavone demonstrated significant cytotoxic activity in vitro. Against human leukemia cell line, HL-60, their IC_(50) was 2.8, 1.9, 7 μg/cm~3, respectively, and against human epidermal carcinoma of oral cavity, KB cell line, IC_(50) was 8.1, 5.2, 15 μg/cm~3, respectively. All these compounds were, for the first time, isolated from the products of marine actinomycetes.国家"863"计划资助项目(2001AA620401);; 国家自然科学基金资助项目(0030007024);; 福建省自然科学基金资助项目(F99032)
