HIV Infection,Sexual Behaviors,Sexual Networks,and Drug Use Among Rural Residents in Yunnan Province,China

This cross-sectional study examined HIV prevalence, sexual behaviors, sexual networks, and drug use among 591 participants from a rural community in Yunnan Province, China. Face-to-face interviews were conducted to collect information about sexual behavior, drug use, and sexual networks. Blood samples were collected and tested for HIV. Of the participants, 52.6% were male and 62.6% were Jingpo minority. The HIV prevalence was 5.5% overall and highest among the Jingpo minority (7.7%). Most participants were sexually experienced and 32.5% had had multiple sex partners. About 18.8% had used drugs, with the highest proportion among the Jingpo minority. HIV infection was independently correlated with drug use among males and with multiple sexual partnerships among females. A total of 336 independent sexual network components (mostly small, linear, and acyclic) were constructed. Eighty-percent were dyads involving two members and 20% involved three to 71 members. Coupled with the promotion of condom use, gender- and network-specific efforts are needed for HIV prevention targeting ethnic minorities in Yunnan.

The MR imaging diagnosis of liver diseases using gadoxetic acid: Emphasis on hepatobiliary phase

The far delayed phase image referred to as the hepatobiliary phase makes the sensitivity of detection for malignant focal hepatic lesions increased, but specificity of malignant diseases, including hepatocellular carcinoma, metastasis and cholangiocarcinoma, characterization remained to be undetermined.
