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)
BACKGROUND Secondary degeneration of the pyramidal tract distal to the primary lesion after a stroke has been detected by some studies using diffusion tensor imaging (DTI) but its potential clinical significance and the degeneration of the fibre tract proximal to the primary lesion have received little attention. METHODS Twelve patients underwent DTI on(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)
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)
BACKGROUND Until now there has been no data to show the effectiveness or benefits of screening for syphilis in gravidas in China. This study was to assess the effectiveness of a program preventing mother-to-child-transmission of syphilis and to reveal factors impacting the benefit. METHODS A cohort of 159,017 gravidas were screened for syphilis by(More)
BACKGROUND Despite the use of a series of preventive measures, a high incidence of severe acute respiratory syndrome (SARS) was observed among health care workers (HCWs) during the SARS epidemic. This study aimed to determine which preventive measures may have been effective in protecting HCWs from infection, and which were not effective. METHODS 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)
In this work, we designed and developed a two-stage delivery system composed of enteric capsule and cationic nanoparticles for oral delivery of insulin. The enteric capsule was coated with pH-sensitive hydroxypropyl methylcellulose phthalate (HP55), which could selectively release insulin from nanoparticles in the intestinal tract, instead of stomach. The(More)
The purpose of this study was to assess trends in the HIV epidemic and risk factors for HIV infection among men having sex with men (MSM) in mainland China. A literature review was conducted. Data from studies regarding HIV prevalence, syphilis infection and risk behavior, were pooled into three chronological stages. The independent correlates of HIV(More)
