BACKGROUND In Western countries depression is the most common psychiatric condition in older persons and related to low socioeconomic status and low social supports. Along with social deprivation, the rural communities in China retain many Chinese traditions that involve high levels of social supports. Studying such a population might offer insights into(More)
OBJECTIVES Environmental tobacco smoke (ETS) has a range of adverse health effects, but its association with dementia remains unclear and with dementia syndromes unknown. We examined the dose-response relationship between ETS exposure and dementia syndromes. METHODS Using a standard method of GMS, we interviewed 5921 people aged ≥60 years in five(More)
Expression of monocyte chemoattractant protein-1 (MCP-1) and CC chemokine receptor 2 (CCR2) and its significance has been demonstrated in some cancer cells in recent clinical studies. However, the role of tumor MCP-1 and CCR2 expression in non-small cell lung cancer (NSCLC) remains unknown. The aim of the present study was to investigate the prognostic(More)
BACKGROUND Depression and dementia often exist concurrently. The associations of depressive syndromes and severity of depression with incident dementia have been little studied. AIMS To determine the effects of depressive syndromes and cases of depression on the risk of incident dementia. METHOD Participants in China and the UK aged > or =65 years(More)
Phosphatase and tensin homolog (PTEN) is a tumor suppressor involved in multiple cell processes. To investigate the role of PTEN in the development of gastric carcinoma, we determined the expression pattern of PTEN in primary gastric carcinoma and in paired adjacent non-neoplastic tissue. We also determined the correlation of PTEN expression with(More)
Glycine receptor (GlyR) activation by glycine protects cells against ATP depletion. However, the underlying mechanisms remain unclear. To define signaling pathways responsible for the GlyR mediated cytoprotection, we examined the phosphorylation status of key kinases signaling pathways in Madin-Darby canine kidney (MDCK) cells. Our results indicated that(More)
We describe a novel functional interaction between ASK1 and PRMT5. We show that PRMT5 interacts with and methylates ASK1 at arginine residue 89 and thereby negatively regulates its activity by promoting the interaction between ASK1 and Akt and thus phosphorylating ASK1 at serine residue 83. Furthermore, the association between ASK1 and Akt is enhanced by(More)
OBJECTIVE Previously published studies of prevalence of depression in older people in China showed much variation in the results, while the pooled prevalence is low. In this study we used a standardised method, the Geriatric Mental State (GMS) to investigate the prevalence of depression in older people in China, validate the GMS-AGECAT depression cases and(More)
We aimed to investigate the expression pattern of phosphatase and tensin homolog (PTEN), to evaluate the relationship between PTEN expression and clinicopathological characteristics, including fatty acid synthase (FAS) expression, and to determine the correlations of PTEN and FAS expression with survival in Chinese patients with hepatocellular carcinoma(More)
Fatty acid synthase (FAS) is the key enzyme regulating de novo biosynthesis of fatty acids. FAS overexpression has been found in many types of tumors and is associated with poor survival. However, the expression of FAS and its relationship with prognosis in Chinese patients with gastric carcinoma are still unknown. Therefore, in this study, we examined the(More)
