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)
An aquaporin protein AcPIP2 from Atriplex canescens was involved in plant growth rate, abiotic stress tolerance in Arabidopsis. Under limited water condition, AcPIP2 leaded to the sensitivity to drought stress. An aquaporin protein (AcPIP2) was obtained from the saltbush Atriplex canescens, which was in PIP2 subgroup belonging to the PIP subfamily, MIP(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)
Little information is available on gene expression profiling of halophyte A. canescens. To elucidate the molecular mechanism for stress tolerance in A. canescens, a full-length complementary DNA library was generated from A. canescens exposed to 400 mM NaCl, and provided 343 high-quality ESTs. In an evaluation of 343 valid EST sequences in the cDNA library,(More)
An ErbB-3-binding protein gene AcEBP1, also known as proliferation-associated 2G4 gene (PA2G4s) belonging to the M24 superfamily, was obtained from the saltbush Atriplex canescens. Subcellular localization imaging showed the fusion protein AcEBP1-eGFP was located in the nucleus of epidermal cells in Nicotiana benthamiana. The AcEBP1 gene expression levels(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)
