BACKGROUND The deleterious biological effects of low-level, long-term exposure to heavy metals are well known, and children are the most susceptible population. Dabaoshan Mine in the southeast of Guangdong Province is at high risk of discharging multi-metals pollutants into a local river (Hengshihe) and the surrounding area. The present study aimed to(More)
OBJECTIVE To assess the prevalence of anxiety and depressive symptoms among patients with somatic diseases in urban China. METHOD A hospital-based cross-sectional study was carried out in four major cities of China from June to August in 2004. There were 2111 eligible subjects with Stroke, Parkinson's Disease, Epilepsy, Irritable Bowel Syndrome,(More)
BACKGROUND Aberrant methylation of promoter DNA and transcriptional repression of specific tumor suppressor genes play an important role in carcinogenesis. Recently, many studies have investigated the association between cigarette smoking and p16(INK4α) gene hypermethylation in lung cancer, but could not reach a unanimous conclusion. METHODS AND FINDINGS(More)
OBJECTIVE The present study aimed to examine the association between maternal passive smoking during pregnancy and the risk of spontaneous PTD and to explore the potential interaction of the single or joint gene polymorphism of CYP1A1 and GSTs with maternal passive smoking on the risk of spontaneous PTD. METHOD We investigated whether the association(More)
OBJECTIVE The objective of this study was to assess the association of psychological stress and social support with anxiety and depressive symptoms in peritoneal dialysis (PD) patients with end-stage renal disease (ESRD). METHODS Eighty-one patients receiving PD were recruited. Their demographic characteristics, psychological stress, and social support(More)
BACKGROUND The Dabaoshan mine in the southeast of Guangdong Province, China, is at high risk of multi-metal pollutant discharge into a local river (Hengshihe) and the surrounding area. Following approximately 30 years of exposure to these metals, little is known regarding the subsequent health effects and risks for the local residents. In our present study,(More)
BACKGROUND The prevalence of chronic kidney disease (CKD) has increased and will continue to rise worldwide. However, data regarding the prevalence of CKD in a rural area of China are limited. We therefore investigated the prevalence and associated risk factors of impaired renal function and urinary abnormalities in an adult rural population in southern(More)
BACKGROUND There is an inverse relationship between febrile infection and the risk of malignancies. Interferon gamma (IFN-γ) plays an important role in fever induction and its expression increases with incubation at fever-range temperatures. Therefore, the genetic polymorphism of IFN-γ may modify the association of febrile infection with breast cancer risk.(More)
