Objective To observe the therapeutic effect of LongXueJieJiaoNang,a compound TCM preparation,on AIDS cases complicated with peripheral neuropathy.Methods Randomized double blind and double center prospective study was conducted for 62 AIDS cases which were divided into two groups: group A with 0.6g LongXueJieJiaoNang t i.d.,and group B with 0.5g inositol,t.i.d,for 2 months(60 days),and then the therapeutic effects were compared between the 2 groups.Results The symptoms,right common peroneal nerve sensory conduction velocity(RSCV),palmesthetic threshold were improved in the two groups with the group A better than the gtoup B(the rates of improvement were 78.0% and 48.4%、66.1% and 30.6%、67.7% and 48.4%,respectively).The total effective rate was 74.4% in group A and 37.5% in group B.Conclusion LongXueJieJiaoNang is effective for AIDS cases complicated with peripheral neuropathy.

Objective To study the metabolism of amino acids in AIDS patients for the purpose of providing appropriate nutritional support.Method High performance liquid chromatography combined with pre-column derivatization technology was used to detect free amino acids in plasma from 22 untreated AIDS patients,16 HAART treated AIDS patients and 30 healthy controls.Statistic analysis was performed through SPSS software.Results The concentration of alanine(Ala) was significantly increased and the concentration of phenoalanine(Phe) was remarkably decreased in AIDS patients as compared with the healthy controls(P

Objective To investigate the awareness of HIV/AIDS and risk behaviors among migrant workers at construction sites in Beijing. Methods The methods of cluster sampling was employed,a questionnaire survey was administered among 1000 migrant workers from two construction sites and a face-to-face interview with the informed consent was conducted in a limited scope.Results There was considerable disparity in the awareness of the routes of AIDS transmission;66.8% of the migrant workers were aware that the condom could reduce the risk of infection,but 51% of them had never used it.Only 2.3% of the migrant workers had sexual intercourse with female sex workers.Conclusion Although the migrant workers under survey have some basic knowledge on HIV/AIDS,their essential understanding was mostly vague,and financial condition have restricted to a great extent their risk behaviors.

Objective Health promotion aims to empower people to enjoy good health by providing conditions at the micro-,meso-and macro-levels.So the organizational culture on which the target population rely in their daily lives should be considered as specific context for promoting their healthy behavior at the micro-level.The study of BANBANCHA,a specific form of sex industry in LZ city of southwest China,has revealed that it is characterized with culture of quasi-family and commercial sense.Accordingly,a relevant HIV prevention strategy has been developed,such as motivating the boss to participate in peer education,involving marketing discourse in health promotion,encouraging the target population to care for their own health,and integrating public and private topics into the health education activities.

Objective To explore a legal system which helps to provide effective HIV prevention and treatment for commercial sex workers.Method A method of literature review was adopted to analyse the major international literature on the interaction between sex work law and HIV prevention and treatment.Results In an international perspective,there are generally three types of legal frameworks of sex work:prohibitive law,law of regulating sex work through licensing,and decriminalization of sex work.In terms of public health,the prohibitive law drives sex workers to the underground state,hindering HIV/AIDS prevetion and treatment;the law of regulating sex work through licensing is unable to deal with the health problems of the unlicensed sex workers;decriminalization of sex work can not only avoid driving sex workers to the underground state,but can also advance HIV/AIDS prevention and treatment by providing integrated health service and behavioural interventions.Conclusion Among the three legal approaches to sex work,decriminalization of sex work provides the most enabling legal framework for HIV prevention and treatment in sex work community.

Sexual transmission of HIV-1 has recently become the predominant route over the world.As an effective HIV vaccine has been elusive so far,microbicides,which are usually applied at topical mucosal sites to prevent vaginal or rectal mucosa from HIV-1 infection,have been paid ever increasing attentions.The failure of previous clinical trials have demonstrated that it is critical to ensure the safety and efficacy of microbicides before they move forward into clinical trials.In this review,we have summarized recent progress in preclinical models evaluating the safety and efficacy of microbicides,including cell culture in vitro,mucosal explant and animal models in vivo which are used at different phases during the preclinical development of microbicides,and have elaborated the characteristics of these models and their advantages.Finally,we emphasize the urgent need to establish effective evaluation systems at molecular levels for different models,which may serve as good surrogates to predict the inflammation and HIV infection in future clinical testing.

Objective To analyze the results of human papillomavirus(HPV)DNA genotyping detection in 312 female outpatients attending STD clinics.Methods HPV DNA genotyping was detected by fluorescent quantitative polymerase chain reaction(FQ-PCR)for 312 samples collected from female outpatients attending STD clinics.Results The HPV detection rates in outpatients with HPV in their neoplasm and secretion were 83.8% and 38.1%,respectively,and the difference between the two groups had statistical significance.Of the 111 cases with visible neoplasm 4,5 and 57 cases were with 16,18 and 6/11 single type HPV infection,respectively,while 0,16,8 and 3 cases were.with 16+18,16+6/11,18+6/11 and 16+18/11 multiple type infection,respectively.Of the 201 cases with abnormal secretion including cases with other STDs,cases with CA and other STDs in their spouses,treated cases with CA,and cases asking for self-examination because of their risky sex behavior,15,12 and 43 were with 16,18,and 6/11 single type infection,respectively,while 2,5,1 and 0 cases were with 16+18,16+6/11,18+6/11,16+18+6/11 multiple type infection,respectively.Conclusions High HPV DNA rates were detected in neoplasm and secretion of female STD outpatients;although the low risk 6/11 type HPV infection was the main cause,the common high risk type HPV infection was also detected.Therefore,routine HPV DNA detection should be provided to this population group.

Objective To study the status of continued heroin/amphetamine abuse among MMT outpatients and related factors.Method Urine analysis was conducted for randomly sampled MMT outpatients,and the results were recorded and analyzed by considering the basic conditions of the tested subjects.Results Of the 179 sampled MMT outpatients,39.1%(70/179) admitted continuing to use drugs,of whom 16.2%(29/179) used heroin,18.4%(33/179) used ice,and 4.5%(8/179) used heroin and methamphetamine in combination;gender difference and regular methadone administration were two factors which were related to the continued drug abuse among them.There were no obvious differences between the outpatients who abused heroin and those who abused ice.Conclusion Serious attention should be given to multiple drug abuse among MMT outpatients and to the risk of new emerging drugs.

Objective To investigate self efficacy of condom use among mobile female population and to analyze related factors so as to provide evidence for relevant interventions.Methods One hundred and eighteen women working as waitresses in hotels in Beijing were interviewed with questionnaires.Results The average score of self-efficacy of condom use among the studied women was 45.42?8.26,and the self-efficay of condom use among them varied with their age,marital status and incomes;their attitude towards condom use and knowledge about correct condom use had obvious effect on the score of self-efficacy.Conclusion Mobile female population have a middle level of condom use self-efficacy,and there is a need to improve their condom use efficacy through training,especially for those unmarried young women with lower incomes.

The male sex worker(MSW)is a special population group who gain money or other material recompenses by offering sex service to male or female clients.Differing from the general population,they have specific demographic and AIDS-related characteristics Their risk behaviors have resulted in high prevalence rate of HIV and other sex transmitted infection among them,and meanwhile have induced them to engage in sex service.
