BACKGROUND Human immunodeficiency virus (HIV) has rapidly spread among men who have sex with men (MSM) in China in recent years; the magnitude of the epidemic is unclear. We sought to test 3 hypotheses: (1) The prevalence of both HIV and syphilis among MSM in China is high, (2) the 2 epidemics each have unique geographical distributions, and (3) demographic(More)
BACKGROUND Before 2003, little was known about the scale of China's HIV/AIDS epidemic. In 2003, the Chinese government produced national estimates with support from the Joint United Nations Programme on HIV/AIDS, the World Health Organization and the United States Centers for Disease Control and Prevention. Subsequent national estimation exercises were(More)
In this paper, the corrosion resistance of laser-welded composite arch wire (CoAW) with Cu interlayer between NiTi shape memory alloy and stainless steel wire in artificial saliva with different concentrations of protein was studied. It was found that protein addition had a significant influence on the corrosion behavior of CoAW. Low concentration of(More)
China's methadone maintenance treatment program was initiated in 2004 as a small pilot project in just eight sites. It has since expanded into a nationwide program encompassing more than 680 clinics covering 27 provinces and serving some 242 000 heroin users by the end of 2009. The agencies that were tasked with the program's expansion have been confronted(More)
The effect of serum starvation and olomoucine treatment on the cell cycle and apoptosis of goat skin fibroblasts cultured in vitro is reported in this paper. The cells were obtained from the ear of a female goat 1.5 years of age. Analysis of cell cycle distribution by fluorescence-activated cell sorting (FACS) showed that 3.4, 60.8 and 15.1% of normally(More)
BACKGROUND Dehong Prefecture in Yunnan Province, China, borders Myanmar. Its proximity to the 'Golden Triangle', one of the world's largest illicit drug production and distribution centre, contributes to drug trafficking and ready availability of heroin. Dehong's 1.1 million people confront a serious HIV problem fuelled by injection drug use. The aim of(More)
The effect of eCG on follicular development and granulosa-cell apoptosis in sexually mature and immature gilts and on granulosa-cell apoptosis in vitro were studied. The sexually mature gilts were treated with eCG on Day 11 of the estrous cycle, and effects were analyzed at different times after treatment with untreated animals at corresponding stages of(More)
The strategy for monitoring HIV/AIDS in China has evolved with the epidemic. The national HIV/AIDS surveillance system was established in 1985 and sentinel surveillance started in 1995. Initially, 42 sentinel sites were established to monitor the epidemic among certain high-risk groups, including drug users, female sex workers, STD clinic attendees and(More)
BACKGROUND As China continues to commit to universal access to HIV/AIDS prevention, treatment and care services, its HIV/AIDS policies have become increasingly information driven. We review China's key national-level HIV/AIDS policies and discuss policy gaps and challenges ahead. METHODS We conducted a desk review of key national-level policies that have(More)
