ABSTRACT
Objective To understand HIV incidence in community residents and epidemiological characteristics of newly detected HIV infection cases in Dali,Yunnan province.Methods A cohort study was conducted among 146720 community residents who were tested to be HIV negative during 2010-2011,they were followed-up from June 1,2014 to May 31,2015.Results A total of 136356 community residents received follow up (92.9％).The follow-up time was 0.23-5.40 years (medium:3.43 years),cumulatively 459675 person years,and 78 people were found to be HIV positive.The incidence rate of HIV infection was 0.170/1000 person years.The incidence rate was 0.037/1000 person years in age group 15-29 years,0.288/1000 person years in age group 30-44 years,0.210/1000 person years in age group 45-59 years,0.204/1000 person years in age ≥60 years;0.213/1 000 person years in males,0.130/1000 person years in females;0.248/1000 person years inHan ethnic group,0.149/1000 person years in Minorities;0.194/1000 in people with education level ≤junior middle school,0.046/1000 person years in people with education level ＞ junior middle school;0.070/1000 person years in the unmarried,0.194/1000 person years in the married and 0.425/1000person years in the divorced/widowed.Cox proportional hazards regression analysis showed that being male (HR=l.731),aged 30-44 years (HR=13.158),aged 45-59 years (HR=10.329),aged ≥60years (HR=8.291),unmarried (HR=3.162) and divorced/widowed (HR=2.689) were the risk factors for HIV infection,while the education level ＞ junior middle school (HR=0.132) was the protective factor for HIV infection.Conclusions By medium 3.43 years follow up,the cohort study showed that incidence rate HIV infection was 0.170/1000 person years in the community residents in Dali.Male,middle aged and old people,people with low education level,the unmarried and the divorced/widowed had relatively higher risk to be infected with HIV,Close attention should be paid to the prevention and control of AIDS in these populations.
ABSTRACT
Objective To explore the levels of autoimmune antibodies and endocrine hormones in patients with endometriosis complicated with infertiilty.Methods 158 endometriosis and infertility patients were selected as study subjects,and they were divided into endometriosis complicated with infertility group(A group,52 cases),endometriosis group(B group,50 cases) and infertility group(C group,56 cases) according to the type of disease.At the same time,93 healthy women were selected as control group.The autoimmune antibodies such as anti-endometrial antibody(EMAb),anti-chorionic gonadotropin antibody(HCGAb),anti-sperm antibody(ASAb),anti-cardiolipin antibody(ACAb) and anti-ovarian antibody(AOAb),endocrine hormones such as luteinizing hormone(LH),follicle stimulating hormone(FSH),prolactin(PRL),estradiol(E2),insulin(INS) and testosterone(T) were compared in four groups.Results There was no significant difference in the total antibody positive rate between B group and C group (χ2=2.161,P＞0.05).The total antibody positive rate of A group was significantly higher than that of B,C group and the control group,the difference was statistically significant(χ2=6.316,P＜0.05).The PRL and INS levels of A group were much higher than those of B,C group and the control group,the differences were statistically significant(F=15.625,10.431,all P＜0.05).The E2,INS and PRL levels of B group were much higher than those of C group and the control group(F=10.363,9.515,9.037,all P＜0.05).The E2,T,INS and PRL levels of A group were much higher than those of B and C group,the differences were statistically significant (F=5.029,6.225,6.631,7.106,all P＜0.05).The LH and FSH levels of the four groups had no significant differences(F=2.385,2.531,all P＞0.05).There were no significant differences in all of the endocrine hormones between C group and the control group(t=1.535,0.931,0.825,1.363,1.005,1.259,all P＞0.05).Conclusion The main factors that cause endometriosis patients complicated with infertility may be due to a endometriosis immune imbalance of T,E2 and PRL and endocrine abnormalities,through the analysis of the levels of autoimmune antibodies and endocrine hormones can provide a reliable basis for clinical.
