BACKGROUND AND PURPOSE The prevalence of constipation after stroke varies from 30% to 60%. The incidence of new-onset constipation during the early stage of stroke remains uncertain. The present study was designed to investigate the prevalence of new-onset constipation, its risk factors, and its impact on stroke outcome in patients with their first stroke(More)
We report the results of a review of the Chinese- and English-language literatures on service delivery in China, asking how well China's health-care providers perform and what determines their performance. Although data and methodological limitations suggest caution in drawing conclusions, a critical reading of the available evidence suggests that current(More)
Men who have sex with men (MSM) may account for an increasing proportion of China’s HIV epidemic, but remain difficult to access for epidemiological studies due to high stigma. We compare the composition of two samples of MSM obtained in Guangzhou, China. The first survey, conducted in 2004, recruited MSM through convenience sampling. The second survey in(More)
Kallikrein, a serine proteinase, has been identified as an angiogenic growth factor recently. We investigated whether delayed treatment with exogenous kallikrein enhances neurogenesis and angiogenesis after focal cortical infarction in stroke-prone renovascular hypertensive rats. Human tissue kallikrein (1.6 x 10(-2) PNAU/kg) or vehicle was given through a(More)
We investigate whether Nogo-A is involved in the secondary axonal degeneration in the thalamus after distal middle cerebral artery occlusion (MCAO) in stroke-prone renovascular hypertensive rats (RHRSP). The expression of Nogo-A in ipsilateral ventroposterior nucleus (VPN) of the thalamus in RHRSP was observed at 1, 2 and 4 weeks after distal MCAO. In(More)
BACKGROUND Cerebrovascular complications are severe events following orthotopic liver transplantation (OLT). This study aimed to observe the clinical and neuroimaging features and possible risk factors of in-hospital cerebrovascular complications in the patients who underwent OLT. PATIENTS AND METHODS We retrospectively reviewed 337 consecutive patients(More)
BACKGROUND Methadone maintenance treatment (MMT) has been successfully scaled up nationally in China. However, the program faces problems of poor attendance and high rates of continued drug use. We assessed whether a contingency management (CM) intervention implemented by MMT clinic staff could improve treatment attendance and drug abstinence. METHODS(More)
BACKGROUND Rapid economic development in urban China has led to a mass migration of surplus rural residents into urban areas for better employment opportunities. This study aims to identify prevalence levels and risks of sexually transmitted infections (STIs) and hepatitis among the rural-to-urban migrant population in China. METHODS Chinese and English(More)
To study the differences in functional brain networks between eyes-closed (EC) and eyes-open (EO) at resting state, electroencephalographic (EEG) activity was recorded in 21 normal adults during EC and EO states. The synchronization likelihood (SL) was applied to measure correlations between all pairwise EEG channels, and then the SL matrices were converted(More)
OBJECTIVES The objectives of this paper are: (1) to estimate the transition probabilities among self-rated health status for the oldest Chinese aged 80 and above; (2) to project the future need of long-term care due to changes in demography and health status among the oldest Chinese. METHODS Self-rated health data collected in Chinese Longitudinal Healthy(More)
