Objective To understand the HIV infection status among pregnant women in Henan province and provide basis for preventing mother to child transmission of AIDS.Methods The HIV-test results obtained from January 2005 to May 2007 among pregnant woman in 31 counties(districts)with relatively high HIV prevalence were analyzed.Results A total of 720 605 pregnant woman were tested for HIV antibody,of whom 541 were identified HIV positive and the HIV-positive rate was 0.08%.Of the 364 HIV positive pregnant women 223(61.26%)decided voluntarily to terminate pregnancy,while 136(37.88%)chose to continue with their pregnancy,and the proportion of HIV positive pregnant women who continued with the pregnancy in the 3 different years was 31.51%(46/146),36.31%(57/157)and 54.10%(33/61),respectively,showing an yearly rising trend.Of the 284 HIV positive mothers 250(88.03%)received PMTCT intervention.Conclusion The rate of PMTCT in HIV-positive pregnant women can be further improved by increasing HIV testing among pregnant women and HIV positive women of child bearing age and by early identifying and managing them.

Objective To observe the clinical efficacy of antiretroviral therapy(ART)or highly active antiretroviral therapy(HAART)for HIV/ AIDS patients in Duan county,and its side effects and CD4 levels in the whole blood.Methods One hundred and nine HIV/AIDS cases admitted to our department in the past 2 years were observed in terms of weight change,control of opportunistic infections,improvement of survival and quality of life,side effects and CD4 levels in the whole blood in 3 months after the combined ART.Results Of the 109 cases 78 patients had weight loss before the treatment and all of them gained weight after the treatment,the changes of body weight were significantly different before and after the treatment(P

Objective To summarize the practice of AIDS prevention and treatment in rural areas of Henan province and to explore a community-based integrated AIDS prevention and treatment model.Methods In the context of the existing 3 tier(county-township-village)rural health care systems,several approaches were adopted including scientific management of HIV-infected persons,patient tracking,laboratory testing,maternal-to-child transmission block,high-risk intervention,health education and medical treatment.Results By the end of 2008,AIDS mortality rate dropped to 4.57 %,the rate of mother-to-child transmission reduced to 4.16%,and the sero-conversion rate among HIV positive single spouses was 1.13/100 person per year;the proportion of persons who continued to receive medical care after 12 month therapy was 85.2%;the rate of HIV related knowledge among the public was 82.3%;the coverage of HIV preventive service among CSWs was as high as 96.98%;the rate of condom use among institution-based CSWs in the last sex trade was 89.54%;the proportion of CSWs who had correct understanding of sex route of HIV transmission was 81.17%,and the rate of persistent use of condom among HIV infected persons and AIDS patients reached 92.57%.Conclusion The community-based integrated AIDS prevention and control model in rural areas of Henan province has achieved remarkable outcomes and it is suggested that such a model should be employed in areas where HIV/AIDS is relatively prevalent.

Objective To analyze the pathogenic characteristics of Chlamydia,Mycoplsma,Neisseria gonorrhoeae,Trichomonas,Candida and Herpes simplex virus in patients with urogenital infections and study the relevant influential factors.Methods Genital secretions of the patients who were suspicious of non gonococcal urethritis(NGU)were collected as samples to detect and cultivated Chlamydia trachomatis(Ct),Ureaplasma urealyticum(Uu),Mhominis(Mh),Neisseria gonorrhoeae(Ng),Candida(Cd),Trichomonies and the type 2 Herpes virus.At the same time,surveys with structured questionnaire were conducted.Results In the 977 detected patients,the rate of positive expression of Ct was 33.67%(329/977),Uu-16.1%(156/977),Mh-7.36%(72/977),N-2.56%(25/977),Cd-4.7%(46/977),Tv-2.87%(28/977),and HBS-2-0.72%(7/977).The rate of co-infections of two or more pathogens(mainly between Ct,Uu,Ng ang Cd)was 10.03(98/977).About 25.85% of the patients in the positive Ct and Uu group were infected without symptom.90% of NGU patients were sex active,aged 18～49 years and most of infections occurred in age group of 30～39 years.Positive rate of Ct,Uu and Cd was higher in females than in males.The infection rate due to ex-marital sexual contact was 65.30% among all the NGU patients.Conclusions(1)The Ct,Uu,Ng and Cd have a higher positive detection rate in the NGU patients in the STD clinic.(2)Co-infection with two or more pathogens are common in the NGU patients.(3)We should pay more attention to the patients with no symptoms.(4)Epidemics and transmission of NGU is largely related with a number of risk factors.

Objective To understand the attitude of health workers towards people living with HIV and AIDS(PLWHA) and AIDS knowledge and desire for related training among them in selected hospitals in Beijing.Method Convenience sampling was used to select health workers from 32 hospitals of different levels in 4 districts within Beijing.Anonymous self-administrated questionnaires were used to collect the information regarding AIDS knowledge and desire for relevant training.Results A total of 1 292 health workers completed the questionnaire.They demonstrated a moderate level of general AIDS knowledge,but a low level of knowledge related to AIDS diagnosis and therapy.Of them 39.7% had received specialized AIDS training and 96% had strongly desire for such specialized training.Most health workers sympathized with PLWHA and understood their situation,while some of them were afraid of PLWHA and wanted to have minimal contact with PLWHA.91.3% of the health workers expressed that PLWHA should have the same rights to medical services.At the same time,49.2% of the health workers stated that they would not like to work in hospitals or departments which accepted PLWHA.80% of the health workers expressed concern over acquiring HIV infection in the workplace.52.7% of them thought that they had a risk of becoming infected in the workplace.Conclusion The level of AIDS knowledge among health workers in Beijing needs to be improved.Specialized training to enhance and develop health workers knowledge of prevention,diagnosis and treatment of AIDS is required.Most of the health workers do not discriminate against PLWHA,but they express concern over infection in the workplace.

Objective To develop an accurate understanding of the policy impact of China-UK HIV/AIDS Prevention and Care Project.Methods Questionnaires and face-to-face interviews were employed for 20 key informants in Beijing including government officials,NGO workers,medical professionals,scholars,police officers,and representatives of international organizations involved in AIDS issues in China.Results The project was noted for its scale and a strong guarantee for fund allocation.It was also noted for having broken some policy taboos.The experience gained from the project was integrated into local policy development and became the evidence base for national policymaking.Conclusion Guided by scientific evidence,the China-UK Project has produced excellent experience for developing national AIDS prevention and control strategy by applying pilot-study based management and making continuous improvement through practice,but its sustainability is challenged when the Project ends.

Objective To understand HIV/AIDS related knowledge and attitude among different population groups in Rizhao.Method Self-designed questionnaires were used to investigate HIV/AIDS related knowledge and attitude among rural and urban residents,hotel attendants and government officers.Results The rates of right answers on HIV/AIDS related questions among the government officers,the urban residents,the hotel attendants and the rural residents were 83.38%,72.45%,72.33% and 66.36%,respectively.Conclusion Although different population groups in Rizhao city have relatively high awareness of HIV/AIDS,there still exist some deficiencies,and consequently education and publicity in this respect should be further strengthened.

Objective To analyze the current situation of voluntary counseling and testing(VCT) and improve HIV/AIDS prevention and control in Jiangxi province.Method VCT services in the province were analyzed using descriptive methodology.Result The province is in shortage of full time VCT workers.Of the individuals receiving pre-testing counseling,those receiving post-testing counseling and receiving referral counseling accounted for 5.22% and 1.39%,respectively.The individuals receiving tests mostly were aged 20-29 years,and a little less were aged 30-39 years.Higher positive rates of HIV screening tests were found in Pingxiang and Nanchang cities,accounting for 39.13% and 26.09%,respectively.Conclusion To improve VCT service and contain the spread of HIV/AIDS in this province,it is necessary to establish VCT networks,upgrade quality of counseling service and publicize VCT and its outreach activities among target population.

Objective To analyze the data of HIV antibody mass screening in Tianjin from 2005 to 2006 and to evaluate current screening strategy.Methods Confirmation tests were conducted for 601 samples received form HIV screening laboratories in Tianjin in line with the procedures and methods defined by the National Guideline for HIV/AIDS Detection.Results Of the 601 samples,215 were HIV antibody positive(with complete bands);24 samples were positive with special reactive blots,of which 10 cases were followed up with 7 confirmed to be infected with HIV and with 3 confirmed to be excluded;51 samples were uncertain with indeterminate blots,of which 8 cases were followed up and all were proved to be HIV antibody negative.Conclusion Routine HIV screening as part of medical examinations for patients in health care settings or for detained personnel in police and judicial organizations represents an important approach to detect cases of HIV infection,Samples with special reactive blots or indeterminate blots should be handled with caution;they should be followed up and may be tested by other approaches,such as blot test or viral genome detection.

Objective To investigate the effects of IL-15 eukaryotic expression plasmid on the Ag-specific immune responses induced by HPV 16 E7 vaccine in mice.Methods An eukaryotic expression plasmid encoding IL-15 gene coding region was constructed and named as pcDNA3.1IL-15.Female BALB/c mice were injected intramuscularly with pcDNA3.1-IL-15 and HPV16 E7 gene vaccine.After the immunization,the concentration of serum IFN-? were tested.Single-cell suspensions of splenocytes were prepared from mice and were re-stimulated with HPV16 E7 protein.Then,the T cell proliferation assay was measured by the MTT method.Results The concentration of serum IFN-? in mice after co-injection with pcDNA3.1-IL-15 and pcDNA3.1-E7 was raised to 414.1pg/ml,which was significantly higher than that of mice co-injected with pcDNA3.1 and pcDNA3.1-E7 or mice injected with pcDNA3.1-E7 only(P
