Abstract:
ObjectiveTo explore the knowledge,attitude,occupational protection for AIDS and their related factors among medical workers in Jiangsu province. MethodsMedical workers were chosen from three health institutions of different grade in Taixing,Danyang and Zhangjiagang city with stratified sampling and investigated with a questionnaire. ResultsThe overall awareness rate of AIDS knowledge among the medical professionals was 81.41% and 36.1% of the professionals were still afraid of AIDS,while most of them(83.9%)would not refuse to treat an AIDS patient.After human immunodeficiency virus(HIV)/AIDS occupational exposure,the total rate of correct self-protection practice among the professionals was only 67.8%.Age,education level,professional title,specialities,and whether being trained before were related with the awareness of AIDS knowledge.Gender,age,the grade of the hospital,specialities,and the awareness of the risk of HIV infection were associated with the attitude towards AIDS.Meanwhile,whether the doctors would treat AIDS patients was directly influenced by the doctors'attitude towards AIDS patients(r=0.88,P=0.001).The rate of correct self-protection practice was affected by training status,whether diagnosing cases of HIV/AIDS,and working department. ConclusionThe knowledge related to AIDS is incomprehensive among medical professionals and the risk of HIV infection still exists.The protective behaviors need to be improved among medical professionals.

Abstract:
ObjectiveTo analyze the survival time and related factors of AIDS cases in Wuhan city,Hubei province. MethodsA retrospective cohort study was conducted to analyze the survival time and related factors among 469 AIDS cases.Kaplan-Meier method was used to describe the survival distribution and life table was applied to calculate the survival proportion.Cox proportional hazard model was performed to identify the factors associated with survival. ResultsThe deaths were mainly due to AIDS.For the 469 cases,the average observation time was 23.54±26.99 months.The total mortality was 12.05/1 000 person-months and AIDS related mortality was 9.51/1 000 person-months.The average survival time was 82.85 months(95% confidence interval [95%CI]=77.59-88.10 months)with a 9-year survival rate of 65.21% by the end of the observation.Univariate analysis presented a significant difference (P<0.05) in average survival time of the AIDS patients based on age at diagnosis,education,transmission category,and under highly active antiretroviral therapy(HAART).Results from multivariate Cox regression showed that injection drug users and men who have sex with men were at a lower risk of death after AIDS diagnosis(hazard ratio [HR]=0.318,95%CI=0.132-0.762; HR=0.335,95%CI=0.115-0.969)compared to those with infection route of blood transfusion or blood products.HAART reduced substantially the risk of death(HR=0.022,95%CI=0.011-0.043). ConclusionThe survival time of the AIDS patients varied in transmission categories.HAART is an effective approach to prolong survival of AIDS patients which should be more available and earlier to start.

Abstract:
ObjectiveTo explore influence factors of human immunodeficiency virus(HIV)and syphilis seroconversion among drug users during methadone maintenance treatment. MethodsTotally 4 909 patients from 13 community-based methadone maintenance treatment clinics in Guangdong province were followed-up for 3 years.HIV and syphilis were tested at the baseline and each year of the follow-up.Sociodemographic and drug use related information were collected using a questionnaire at baseline and every 6 months.Urine tests were also carried out by doctors every month to detect whether illegal drug was used during the treatment. ResultsThe seroconversion rate of HIV and syphilis was 0.41/100 person-years and 1.30/100 person-years.Risk factors associated with positive HIV seroconversion were marital status(relative risk [RR]=2.211),frequency of injection drug use(RR=1.023),sexual behaviors in previous 3 months(RR=3.614),syphilis infection status(RR=6.357),and the result of urine test at baseline(RR=3.235).High average dosage of methadone intake(RR=0.966)was a protective factor of positive HIV seroconversion.Female(RR=4.148),older age(RR=1.098),unemployment(RR=1.866),injection drug use(RR=4.515),and intercourse due to drug use(RR=17.910)in previous one month were risk factors of syphilis. ConclusionInjection drug use and sex behavior are risk factors of HIV infection and syphilis.High average dosage of methadone intake is protective factors of HIV seroconversion.

Abstract:
ObjectiveTo evaluate disinfection efficacy of conventional disinfectants against human immunodeficiency virus(HIV). MethodsTwo methods(nucleic acid quantification and cell culture)were used in testing of disinfectant against HIV in blood or plasma. ResultsThe nucleic acid quantification test showed that the log inactivation value for HIV in plasma exceeded 4.00 in the case of HIV exposed to available chlorine of 3 000 mg/L for 5 min,available iodine of 100 mg/L for 1 min or 75% alcohol for 1 min.But for the exposure of peracetic acid 5 000 mg/L for 1 min,the log inactivation value did not exceed 2.00.For the HIV in blood,the concentration of avaiailable chlorine and iodine should be increased for effective disinfection.The cell culture test showed that the log inactivation value exceeded 4.00 in case of HIV exposed to 100 mg/L available chlorine or peracetic acid for 3 min,available iodine 100 mg/L for 1 min,75% alcohol for 30 s,and 0.05% glutataldehyde for 5 min. ConclusionThere are differences in disinfection effect between the two methods.As an indirect indicator of inactivation,nucleic acid quantifecation could be used in the quick screening test while culture is a direct indicator which could be considered as the ultimate determination.

Abstract:
ObjectiveTo study the serological characterization of indeterminate western blot results of human immunoldeficiency virus(HIV)antibody and to find the causes and the influence of the indeterminacy. MethodsThe data for 302 cases with indeterminate HIV antibody western blot profiles and 61 patients receiving follow-up diagnostic testing in Liaoning AIDS Corroboration Center Laboratory from 2007-2011 were analyzed. ResultsThere were 18 strip types in the 302 cases with indeterminate HIV antibody western blot profiles,with the top three types of p24(43.4%,131/302),gp160 p24(19.2%,58/302),and gp160(18.9%,57/302).HIV showed three main structure antigens,with 12 strip types of env(51.0%,154/302),2 strip types of gag (46.7%,141/302),and 4strip types of pol(2.3%,7/302).Among the 61 cases completing the follow-up detection,16(26.2%)were diagnosed as positive.In the 16 positive patients,strip type of env was dominant(93.8%,15/16).For the 61 cases,the proportion of env type was 59.0%(36/61),with significant difference(χ2=12.103,P<0.05).There were 22 indeterminate strip type of gag showed negative result at the end of follow-up. ConclusionThe results indicates that the most common indeterminate HIV western blot profile is gag protein strip for unspecific reaction and the profile of env has more predictive significance for HIV infection.

Abstract:
ObjectiveTo study the changes and determinants of cognitive function and to explore its predictive value to different subtypes of mild cognitive impairment(MCI)among the elderly in Guiyang city. MethodsUsing multistage sampling,2 197 people aged 60 years and older were selected from urban communities in Guiyang for a baseline survey in 2004-2005 and followed up in 2008.The subjects were divided into normal cognitive(NC)and different subtypes of MCI groups according to the outcomes of follow-up examination.The cognitive function was assessed by using the Mini-Mental State Examination(MMSE),and logistic regression model was used to analyze the predictive value of cognitive function for different subtypes of MCI. ResultsA total of 1 409 participants completed follow-up examination,with a follow-up rate of 64.13%.Among the elderly,there were 1 279 with normal cognitive function,72 cases of amnestic mild cognitive impairment(aMCI),34 cases of nonamnestic mild cognitive impairment(naMCI),and 24 cases of dementia.The aMCI cases had a lower score(3.65±0.56)in using vocabulary compared with the normal control group(3.78±0.46)in baseline study.The naMCI cases had lower scores in memory,computing power,visual-spatial ability,and overall cognitive function compared with the normal control group.The scores of memory,computing power,visual-spatial ability,and overall cognitive function in aMCI group decreased to 3.33±2.17,2.26±1.56,0.27±0.63,and 3.97±2.98,respectively.The scores of orientation,ability of using vocabulary,the understanding of language,and overall cognitive funciton in naMCI group declined to 1.59±1.81,0.41±0.70,0.62±1.18,and 3.82±2.61,respectively.After controlling for age,education level and occupation,the memory and ability of using vocabulary showed a value for prediction to aMCI,and so did the computing power and visual-spatial ability to naMCI. ConclusionThere are different changes in cognitive functions among the elderly with different subtypes of MCI and the changes show early predicting value to different subtypes of MCI.

Abstract:
ObjectiveTo study the influencing factors of hospital delivery in remote and poor mountain areas and to provide basis for promotion of maternal hospital delivery in the remote and poor mountainous areas. MethodsA case-control study was carried out in 222 pregnant wome from remote,impoverished mountain areas and without hospital delivery during 2010-2011 and 217 residential place,year of delivery,and ethnic group-matched controls with hospital delivery.Information on influencing factors of hospital delivery were collected with a face-to-face questionnaire survey. ResultsMultivariate logistic regression analysis showed that having first child of non-hospital delivery,the number of prenatal examination,husband's decision for delivery site,with female village doctor in the village,knowledge about maternal health care,examination results of AIDS,syphilis and hepatitis B,and the cost of hospital delivery were main factors affecting the hospital delivery.The direct cause of non-hospital delivery included without enough time because of preterm delivery(47.72%),far distance from the hospital and difficulty in transportation(14.72%),economic difficulty(12.18%),and thinking of no necessity for hospital delivery because of good health condition(10.15%).The top three birth attendants of non-hospitalized delivery were family member(60.8%),midwife(15.8%),and village doctor(13.5%). ConclusionThe influencing factors of hospital delivery involve health education and health promotion,social mobilization,antenatal care,and transfer of treatment.Comprehensive intervention should be carried out to increase hospital delivery rate in remote mountain area.

Abstract:
ObjectiveTo investigate the coverage and its influencing factors of medical insurance among university students and to explore the way to promote the coverage of medical insurance system in the students. MethodsTotally 1 702 college students were selected from four universities with stratified sampling method,and a questionnaire survey was carried out among the students. Results Among the students,the coverage of commercial insurance,basic medical insurance for urban residents,publicly funded free medical care was only 23.87%,39.55%,and 36.58%,respectively. Single factor analysis showed that grade,college,hometown,medical expense per year,self-attention to health,evaluation on necessity of medical insurance,promotion of medical insurance in the college,the students' cognition on commercial insurance,basic medical insurance for urban residents,and publicly funded free medical care were related to the coverage of medical insurance among the students.The results of logistic regression analysis revealed that low evaluation on the necessity of medical insurance(odds ratio [OR]=1.42),promotion of medical insurance in the colleag(OR=1.19),and the students' cognition on commercial insurance(OR=1.17)and basic medical insurance for urban residents(OR=1.76)were inversely correlated to the enthusiasm for medical insurance. The annual medical expenses of students and the enthusiasm for medical insurance were negatively correlated. ConclusionThe new health care system for college students is a complex project,and the efforts of society,college,and the students should be combined to increase the coverage of medical insurance.

Abstract:
ObjectiveTo study the toxicity of lead(Pb)poisoning in rats and the protective effects of selenium(Se)supplementation against the damage caused by Pb. MethodsForty Wistar rats were randomly divided into five groups:control group,180 mg/kg Pb group,270 mg/kg Pb group;180 mg/kg Pb+0.5 mg/kg Se group,and 270 mg/kg Pb+0.5 mg/kg Se group.Pb and Se were administered in the form of lead acetate and sodium selenite in the diet.The rats in the control group were given basal diet.All the rats were anesthetized and blood and organs were collected at the end of 7 weeks.Body weight,ratio of organ/body weight,hematological and enzymatic parameters and blood Pb were analyzed. ResultsThe body weight of the rats in 270 mg/kg Pb group(160.22±20.29 g)and 270 mg/kg Pb + 0.5 mg/kg Se group(148.50±9.11 g)was significantly lower than that in control group(204.60±26.21 g)(P<0.05).The ratio of organ/body weight was changed in 180 mg/kg Pb group,270 mg/kg Pb group and 270 mg/kg Pb+0.5 mg/kg Se group,but not in 180 mg/kg Pb+0.5 mg/kg Se group.The hemoglobin concentration in 180 mg/kg Pb group(12.11±2.06 g/dL),270 mg/kg Pb group(10.24±1.61 g/dL)and 270 mg/kg Pb + 0.5 mg/kg Se group(11.97±1.39 g/dL)were decreased compared with that in control group(16.6±4.30 g/dL)(P>0.05),while the hemoglobin level in 180 mg/kg Pb + 0.5 mg/kg Se group was comparable with that in control group. ConclusionSe at a suitable dose can protect against the damage caused by Pb.
