MSM and HIV/AIDS in China

This article profiles current status of spread and control of HIV/AIDS in China. China has a significant population of MSM （men who have sex with men） and they have been becoming very much alive in many ways since 1990s due to recent social changes. Some surveys indicate that great many of MSM are engaged in high-risk behaviors. In addition, majority of MSM have also experienced sexual encounters with women sometimes in their lives, which possibly contribute to spread of HIV to women. Some reports documented that HIV is becoming rampant among MSM since more than 1% of them are now infected. Political, cultural and custom elements could hinder intervention activities against HIV spread among MSM. Fortunately, many cities in China have seen that MSM were in cooperation with responsible institutions carrying out certain intervention measures. The general situation is promising. The authors forecast that the fast HIV spread among MSM of China could possibly be halted within several years when the authorities become more sensible to this issue, health service institutions offer unswerving efforts toward the MSM community and those who involve in MSM undertakes necessary responsibilities.     

MSM and HIV/AIDS in China

INTRODUCTION The term MSM (men who have sex with men) was introduced into mainland China in 2000. Homosexuals, without identifying gender, were used previously to de- scribe MSM by authorities, the public and even professionals. The first confirmed MSM ca…     

Chinese NGOs in action against HIV/AIDS

Chinese nongovernmental organizations （NGOs） have played a significant role in the battle against AIDS in the People＇s Republic of China. This article provides a brief overview of the structure of these organizations, as well as an analysis of their principle accomplishments. Of great significance in this analysis is the fact that Chinese NGOs have effectively dealt with many sensitive health education areas that government authorities have felt reluctant to handle directly. As such, they have provided an indispensable component in the HIV/AIDS prevention and control calculus on the mainland.

Chinese NGOs in action against HIV/AIDS

INTRODUCTION The AIDS epidemic continues its seemingly inexorable spread throughout the world. It is now very clear that the virus represents not only a medical problem, but also a challenging and multifaceted social problem. Because of this fact, it is imperative that nongovernmental organiza- tions outside of, or tangential to, the medical arena be- come involved in prevention and control efforts. The Chinese government is supportive of the development of such organizations on the mai…     

HIV感染者/AIDS病人高迁移率族蛋白1的表达及其临床意义

通过检测74例处于不同病期的HIV感染者/AIDS患者和10例健康对照者PBMCs中HMGB1 mRNA的表达水平及其外周血浆HMGB1、TNF-a和IL-2水平,比较各组之间表达水平的差异及其与CD4＋T淋巴细胞的关系.发现HMGB1 mRNA的表达水平及血浆HMGB1含量在AIDS病人组明显高于感染者组和正常对照组（P〈0.05）;AIDS患者经HAART治疗后疗效差组HMGB1 mRNA的表达水平及血浆HMGB1含量也明显高于疗效好组（P〈0.05）;而经HAART治疗后效果好且免疫功能恢复的患者HMGB1 mRNA的表达及血浆HMGB1含量均较治疗前明显下降（P〈0.05）;当CD4＋T细胞数低于200/μL时,血浆HMGB1含量以及PBMCs中HMGB1 mRNA表达水平与CD4＋T细胞数呈负相关.显示HMGB1在HIV/AIDS发病及病情进展过程中可能起重要作用,HMGB1血浆含量及PBMCs中HMGB1 mRNA的表达水平高低与HIV/AIDS患者病情轻重密切相关.     

Impulsive SUI epidemic model for HIV/AIDS with chronological age and infection age

This paper develops an impulsive SUI model of human immunodeficiency virus/acquired immunodeficiency syndrome(HIV/AIDS) epidemic for the first time to study the dynamic behavior of this model. The SUI model is described by impulsive partial differential equations. First, the well-posedness of the model is attained by the method of characteristic lines and iterative method. Secondly, the basic reproduction number R₀(q,T) of the epidemic which depends on the impulsive HIV-finding period T and the HIV-finding proportion q is obtained by mathematical analysis. Our result shows that HIV/AIDS epidemic can be theoretically eradicated if we can have the suitable HIV-finding proportion q and the impulsive HIV-finding period T such that R₀(q,T)<1. We also conjecture that the infection-free periodic solution of the SUI model is unstable when R₀(q,T)>1.     

52例HIV／AIDS患者口腔念珠菌病的临床表型及病原学鉴定

目的：口腔念珠菌病（ oral candidiasis,OC）是HIV／AIDS患者中最常见的口腔疾病,研究其临床表型及病原学特点对AIDS相关性口腔念珠菌病的诊断和临床用药有重要的指导意义。方法将70例确诊为HIV／AIDS且初步诊断为AIDS相关性口腔念珠菌病患者使用棉拭子在其病损区取材,接种至科玛嘉念珠菌显色培养基检验。结果 HIV／AIDS患者念珠菌感染的病例为52例,临床表型以假膜型和红斑型为主,其中假膜型最为常见（56％）。 HIV／AIDS患者口腔念珠菌病各致病病原菌以白念珠菌的检出率最高（60．32％）,热带念珠菌次之（19．05％）,光滑念珠菌为（12．70％）,克柔念珠菌（7．94％）。有9例HIV／AIDS伴口腔念珠菌病患者,检测出病原菌的混合感染,其中2例为3种病原菌感染。结论 HIV／AIDS患者口腔念珠菌病临床表型复杂且可以伴发,单纯通过临床表现鉴别诊断常不准确,且病原菌的准确分型可以指导临床用药,降低耐药菌的产生。     

HIV/AIDS患者CD4水平对甲状腺功能影响的比较研究

目的观察HIV/AIDS患者甲状腺功能的变化,了解HIV对内分泌的影响。方法检测168例HIV/AIDS患者TT4、TT3、FT4、FT3、TSH,并分析不同CD4水平对甲状腺功能影响。结果HIV/AIDS患者甲状腺功能可保持正常,但低CD4组的FT3、TSH水平低于高CD4组。结论HIV/AIDS患者甲状腺功能可保持正常,但HIV感染不同阶段会对内分泌系统有一定影响。HIV感染对甲状腺影响的具体机制尚不十分清楚,利用动物模型进行进一步研究非常必要。     

Challenges and Opportunities： the Expanded Government-led HIV/AIDS Programs in China

HIV/AIDS has posed an increasingly serious issue in China. In recent years,Chinese government has taken further intensified efforts to combat HIV/AIDS with high-level political commitment,supportive policy development,increased financial allocation,large-scale of government-led initiatives,expanded international cooperation and great involvement of non-governmental organizations. Meanwhile gaps and challenges coexist impacting the implementation and the results of national HIV/AIDS programs. Thus,further government efforts are needed to improve and tailor the actions to meet the requirement of HIV/AIDS control in China.     

A General Introduction of HIV/AIDS Treatment with Traditional Chinese Medicine in China

This paper gives a general introduction of HIV/AIDS treatment with Traditional Chinese Medicine (TCM) in China during the past 20 years. Although the role of TCM in treatment of HIV/AIDS is promising,there is still a long way to go.     

Injection drug use and HIV/AIDS transmission in China

After nearly three decades of being virtually drug free, use of heroin and other illicit drugs has re-emerged in China as a major public health problem. One result is that drug abuse, particularly heroin injection, has come to play a predominant role in fueling China＇s AIDS epidemic. The first outbreak of HIV among China＇s IDUs was reported in the border area of Yunnan province between China and Myanmar where drug trafficking is heavy. Since then drug-related HIV has spread to all 31 provinces, autonomous regions and municipalities. This paper provides an overview to HIV/AIDS transmission through injection drug use in China. It begins with a brief history of the illicit drug trade in China, followed by a discussion of the emergence of drug related AIDS, and a profile of drug users and their sexual partners who have contracted the virus or who are vulnerable to infection. It ends by summarizing three national strategies being used by China to address both drug use and AIDS as major health threats.     

Injection drug use and HIV/AIDS transmission in China

INTRODUCTION Although sexual transmission accounts for most of the AIDS epidemic globally, HIV/AIDS among injecting drug users (IDUs) is a growing problem worldwide. First de- tected in China in 1989 among drug abusers on the Yunnan border, HIV/AIDS subse…

Mixing as an ethnoetiology of HIV/AIDS in Malaysia's multinational factories

Minah Karan, the stigmatizing label appended to Malay factory women in the 1980s, signaled a dangerous female sexuality that risked spreading beyond the factory gates and infecting Malaysia's idea(l)s of its traditional kampung culture. This article narrates how Minah Karan, as the former antihero of development, was reconstituted in the 1990s, with the government's labeling of factories as high-risk settings for HIV/AIDS. This is an ethnoetiology based not on any evidential epidemiological data but on the racial and gendered mixing that transpires behind factory walls: a fear that the mixing of the sexes means ipso facto sexual mixing among the races. The article demonstrates how importation of the high-risk label articulates at the local level the new and contested linkages, economic, religious, and scientific, constitutive of globalization. The pragmatic nature and imperatives of this high-risk process are discerned in factory women's accounts of how they negotiate the interactional imperatives of factory work, because transnational structures of productivity violate the social boundaries that have long connoted political stability, moral integrity, ethnic community, and individual safety. The article concludes by questioning whether ethnoetiologies, especially when they concern sexual networks, become social etiologies, because this would locate ethnoetiologies as central to conventional public health praxis rather than as ethnographic exotica in the margins.     

Technology and Affect: HIV/AIDS Testing in Brazil

Contemporary techno-scientific and medical developments are restructuring social interactions and the very processes by which individual subjectivity is formed. This essay elaborates on the experiential and ethical impact of such transformations from the perspective of people who, in ordinary and unexpected ways, act science and technology out. We carried out ethnographic research in an HIV/AIDS Testing and Counseling Center (CTA) in northeastern Brazil, combining participant observation with epidemiological analyses and clinical survey. We found a high demand for free testing by low-risk clients, largely working and middle class, experiencing anxiety and complaining of AIDS-like symptoms. Most of the clients were sero-negative and many returned for a second and third testing. We understand this to be a new techno-cultural phenomenon and call it imaginary AIDS. Throughout this essay, we describe CTA's routine practices, place these practices in historical, political, economic and cross-cultural perspective, and analyze the subjective data we collected from the clients of our pilot study. We explore how clinical epidemiological expertise and HIV testing technology are integrated into new forms of bio-politics aimed at specific marketable and disease-free populations, and on the affective absorption of bio-technical truth and the engendering of a technoneurosis in this testing center.     

Relationship of HLA-A, -Cw Polymorphisms with HIV/AIDS in Chinese Yi Ethnic Group of Sichuan Province1

The relationship of HLA-A, -Cw alleles on HIV infection and AIDS disease progression in the Chinese Yi ethnic group of Sichuan province were investigated. The genetic polymorphisms of HLA-A, -Cw alleles of 102 unrelated healthy Chinese Yi ethnic individuals, 68 HIV-1 infected and 21 HIV positive long-time survivors were typed by PCR-SSP assay. Statistic signifiance was determined by the χ^2 test with the SPSS software. No significant differences were observed between the HLA-A, -Cw alleles of the 68 HIV-1 infected and 102 non-infected Chinese Yi control individuals. Whereas the prevalence of A＊3601,Cw＊14（01-03）and Cw＊0304 was significantly higher in 21 long time survivors compared with 102 healthy controls with P values of 0.016, 0.016 and 0.000 by χ^2 or the Fisher exact test respectively. The result implies that A＊3601,Cw＊14（01-03） and Cw＊0304 may be associated with slow AIDS disease progression in the Chinese Yi ethnic group, further studies on this association may yield insight on the pathogenesis of HIV-1 infection.     

Relationship of HLA-A,-Cw polymorphisms with HIV/AIDS in Chinese Yi ethnic group of Sichuan province

The relationship of HLA-A,-Cw alleles on HIV infection and AIDS disease progression in the Chinese Yi ethnic group of Sichuan province were investigated. The genetic polymorphisms of HLA-A,-Cw alleles of 102 unrelated healthy Chinese Yi ethnic individuals, 68 HIV-1 infected and 21 HIV positive long-time survivors were typed by PCR-SSP assay. Statistic significance was determined by the x ² test with the SPSS software. No significant differences were observed between the HLA-A,-Cw alleles of the 68 HIV-1 infected and 102 non-infected Chinese Yi control individuals. Whereas the prevalence of A*3601,Cw*14(01-03)and Cw*0304 was significantly higher in 21 long time survivors compared with 102 healthy controls with P values of 0.016, 0.016 and 0.000 by x ² or the Fisher exact test respectively. The result implies that A*3601,Cw*14(01-03) and Cw*0304 may be associated with slow AIDS disease progression in the Chinese Yi ethnic group, further studies on this association may yield insight on the pathogenesis of HIV-1 infection.
