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)
In this study, we developed an algorithm based on neuromuscular-mechanical fusion to continuously recognize a variety of locomotion modes performed by patients with transfemoral (TF) amputations. Electromyographic (EMG) signals recorded from gluteal and residual thigh muscles and ground reaction forces/moments measured from the prosthetic pylon were used as(More)
This paper presents a real-time implementation of an intent recognition system on one transfemoral (TF) amputee. Surface Electromyographic (EMG) signals recorded from residual thigh muscles and the ground reaction forces/moments collected from the prosthetic pylon were fused to identify three locomotion modes (level-ground walking, stair ascent, and stair(More)
OBJECTIVES To investigate the incidence of syphilis infection and to determine the risk factors related to syphilis infection among young men who had sex with men (YMSM), which were documented for developing effective intervention to prevent sexually transmitted diseases among YMSM. METHODS A cohort study was conducted in 8 cities (Beijing, Shanghai,(More)
China is experiencing an emerging HIV epidemic, primarily affecting the rural poor. For this group, the costs of staying healthy are often beyond their means. A qualitative study was undertaken with 20 HIV-positive people living in a rural area in Anhui, eastern China, 20 of their family members, 20 health care providers, and 20 uninfected villagers. In(More)
OBJECTIVES To assess HIV incidence and its associated risk factors among young men who have sex with men (YMSM) in urban areas, China. DESIGN The study used a prospective cohort study design and standard diagnostic tests. METHODS A twelve-month prospective cohort study was conducted among YMSM (18-25 years old) in 8 large cities in China. The(More)
Stigma is a significant barrier to effective control of HIV/AIDS, despite laws to control it. The purpose of this study was to examine factors associated with HIV stigma in a rural Chinese community. A survey was conducted in north-west Anhui province among 963 residents to assess HIV-related knowledge, attitudes, and behaviors. Participants scored a mean(More)
The Na+-K+-2Cl- cotransporter-2 (NKCC2) has long been recognized as a “kidney-specific” transporter and is important in salt reabsorption. NKCC2 has been found in the gastric mucosa; however, its cellular distribution and function remain obscure. The present study characterized the distribution pattern of NKCC2 in mammalian gastric mucosa and investigated(More)
BACKGROUND Various studies have modeled the impact of test-and-treat policies on the HIV epidemics worldwide. However, few modeling studies have taken into account China's context. To understand the potential effect of test-and-treat on the HIV epidemic among men who have sex with men (MSM) in China, we developed a mathematical model to evaluate the impact(More)
