Major and profound changes have taken place in China over the past 30 years. Rapid socioeconomic progress has exerted a great impact on lifestyle, ranging from food, clothing, working and living conditions, and means of transportation to leisure activities and entertainment. At the same time, new health problems have emerged, and health services are facing(More)
Rice is sensitive to cold and can be grown only in certain climate zones. Human selection of japonica rice has extended its growth zone to regions with lower temperature, while the molecular basis of this adaptation remains unknown. Here, we identify the quantitative trait locus COLD1 that confers chilling tolerance in japonica rice. Overexpression of(More)
In the present study, we hypothesized that postcon (postconditioning) confers cardioprotection in vivo by reducing the production of ONOO- (peroxynitrite) and nitro-oxidative stress subsequent to the inhibition of the iNOS (inducible NO synthase). Patients with AMI (acute myocardial infarct) were randomly assigned to undergo percutaneous coronary(More)
To fulfill its commitment to a successful 2008 Olympic and Paralympic Games, the Chinese government made unprecedented efforts to improve the air quality in Beijing. We report findings on air quality and outpatient visits for asthma among adults in Beijing during the 2008 Summer Olympic Games. Three study periods were defined: summer baseline (June 1-June(More)
BACKGROUND & AIMS Cigarette smoking is associated with inflammatory bowel diseases (IBDs), particularly Crohn's disease, in humans. The aim of this study was to examine whether passive cigarette smoking aggravates experimental IBD in rats and to clarify the underlying mechanisms. METHODS Rats were exposed to cigarette smoke (CS) for 1 hour once daily for(More)
This study was aimed to investigate the prognostic value of neutrophil-to-lymphocyte ratio (NLR) in patients with prostate cancer (PCa). A meta-analysis including 14 publications (15 cohorts) with 16,266 patients was performed to evaluate the association between NLR and overall survival (OS), progression-free survival (PFS)/recurrence-free survival (RFS) in(More)
Our preliminary finding indicated that intravenous (i.v.) injection of heparin increased gastric ulcer healing in rats. However, the anticoagulant action of i.v. heparin could produce complications in ulcer patients if the drug was used as an anti-ulcer agent. The present study aimed to investigate whether intragastric (i.g.) administration of heparin,(More)
BACKGROUND Cigarette smoking was shown to delay gastric ulcer healing and reduce synthesis of mucus, which is important for gastric ulcer protection and healing. Polyamines are important in these processes. AIMS To study the effects of cigarette smoking on the synthesis of mucus and to investigate if such an effect is acting by interference with the(More)
BACKGROUND Oxidized low-density lipoprotein (oxLDL) promotes expression and secretion of endothelin-1 (ET-1), however, the precise mechanism involved is unclear. This study was designed to identify the regulatory mechanism of oxLDL-induced ET-1 expression in endothelial cells. METHODS ET-1 mRNA expression, secretion and promoter activity were evaluated by(More)
To explore the effects of ghrelin on disturbed myocardial energy metabolism during chronic heart failure (CHF). Rats were subcutaneously injected with isoproterenol (ISO) for 10 days with or without ghrelin for another 10 days. Enzyme immunoassay was to measure ghrelin concentrations. Compared with the control group, ISO-treated rats showed suppressed(More)
