BACKGROUND Previous surveys on depression in China focused on prevalence estimates without providing a detailed epidemiological profile. METHOD Face-to-face household interviews were conducted with a multi-stage household probability sample of 2633 adults (age > or = 18 years) in Beijing and 2568 in Shanghai between November 2001 and February 2002. The(More)

BACKGROUND Studies show that poststroke depression (PSD) increases mortality risk at 1 year. However, whether PSD increases the risk of recurrent stroke at 1 year remains unclear. This study was to investigate whether PSD at 2 weeks following a stroke could increase risk of recurrent stroke at 1 year. METHODS AND RESULTS This was a multi-centered(More)
OBJECTIVE There has been no community-based research on treatment delay among people with mental disorders in China. This study examines lifetime treatment and treatment delay in metropolitan China. METHOD A multi-stage probability survey of 5201 respondents was administered in Beijing and Shanghai. Age of first treatment contact after onset of each of(More)
The aim of the present study was to investigate whether chronic administration of basic fibroblast growth factor (bFGF) following angioplasty in a dog model of athero-sclerotic iliac stenosis may restore endothelium function and prevent restenosis (RS). In total, 40 dogs with atherosclerotic stenosis of the right iliac arteries were used in the study. A(More)
Although modulation of the activity of voltage-gated sodium channels (VGSCs) by protein kinase A (PKA) phosphorylation has been investigated in multiple preparations, the pharmacological sensitivity of VGSCs to scorpion toxins after PKA phosphorylation has rarely been approached. In this study, the effects of BmK AS, a sodium channel-specific modulator from(More)
