ThO pathological rOsults aftOr surgOry wOrO usOd as thO gold standard, and thO puncturO succOss ratO, sOnsitivity, spOcificity and accuracy of US -CNB wOrO analyzOd.Results Forty-ninO lOsions wOrO diagnosOd by qualitativO diagnosis, of which 42 lOsions wOrO malignant and 7 lOsions wOrO bOnign. Two lOsions wOrO diagnosOd by qualitativO diagnosis, and thO succOss ratO of puncturO was 96.1% (49/51).ThO postopOrativO pathology confirmOd that 44 casOs wOrO malignant and 6 casOs wOrO bOnign. ThO sOnsitivity, spOcificity and accuracy of US-CNB wOrO 97.7% (42/43),100.0% (42/42),98.0% (48/49),rOspOc-tivOly.Conclusion ThO succOss ratO and accuracy of US-CNB puncturO in thO diagnosis of bOnign and malignant lOsions arO high, consistOnt with thO gold standard.

Study on unprotected anal intercourse behavior in HIV-positive men who have sex with men in the context of knowing their HIV infection status in Chengdu / 中华流行病学杂志

Objective: To identify related factors associated with unprotected anal intercourse (UAI) among HIV-positive men who have sex with men (MSM) in the context of knowing their HIV infection status. Methods: HIV positive MSM who known that they had been infected with HIV for more than 6 months and accepted follow up services were recruited by convenience sampling method in Chengdu 2015. Semi-structured questionnaire was used to collect their information, such as demographic characteristics, antiviral therapy and sexual behavior characteristics etc. Logistic regression model was used for univariate and multivariate analyses. Results: A total of 330 HIV- positive MSM were recruited, 201 eligible MSM were interviewed. The prevalence of UAI in recent six months was 18.41% (37/201). The results of multivariate logistic regression analysis revealed that the number of anal intercourse with male ≥3 in last month (OR=6.22, 95%CI: 1.88-20.56), low education level (OR=7.29, 95%CI: 1.36-39.16), married, divorced or widowed status (OR=4.65, 95%CI: 1.13-19.17), homosexual cohabitation (OR=3.32, 95%CI: 1.01-10.95) were the risk factors related with UAI among the HIV-positive MSM. Conclusion: Frequent homosexual anal intercourse, low education level, married, divorced or widowed status and homosexual cohabitation might be the risk factors related with UAI in HIV-positive MSM in Chengdu.
