MOTIVATION Recently, gene-coexpression relationships have been found to be often conditional and dynamic. Many studies have suggested that single nucleotide polymorphisms (SNPs) have impacts on gene expression variations in human populations. RESULTS The SNPxGE(2) database contains the computationally predicted human SNP-coexpression associations, i.e.(More)
SUMMARY Gene duplication occurs via different modes such as segmental and single-gene duplications. Transposed gene duplication, a specific form of single-gene duplication, 'copies' a gene from an ancestral chromosomal location to a novel location. MCScanX is a toolkit for detection and evolutionary analysis of gene colinearity. We have developed(More)
OBJECTIVES To assess the trend of urban-rural disparities in hospital admissions and medical expenditure between 2003 and 2011 in the context of Chinese health-care system reform. METHODS The data were from three different national surveys: the Third National Health Services Survey in 2003, the Fourth National Health Services Survey in 2008 and the(More)
BACKGROUND It is unclear whether the relationship between cigarette smoking and atopy is mediated by body fat mass, such as the Body Mass Index (BMI). We assessed the mediating role of BMI on the relationship between smoking and atopy in Chinese adults. METHODS A hospital-based case-control study of 786 atopic cases and 2771 controls was conducted in(More)
