BACKGROUND The efficacy of treatments that lower homocysteine concentrations in reducing the risk of cardiovascular disease remains controversial. Our aim was to do a meta-analysis of relevant randomised trials to assess the efficacy of folic acid supplementation in the prevention of stroke. METHODS We collected data from eight randomised trials of folic(More)
BACKGROUND Previous genome-wide association studies for type 2 diabetes susceptibility genes have confirmed that a common variant, rs9939609, in the fat mass and obesity associated (FTO) gene region is associated with body mass index (BMI) in European children and adults. A significant association of the same risk allele has been described in Asian adult(More)
BACKGROUND Trials of beta blockers in patients undergoing non-cardiac surgery have reported conflicting results. This randomised controlled trial, done in 190 hospitals in 23 countries, was designed to investigate the effects of perioperative beta blockers. METHODS We randomly assigned 8351 patients with, or at risk of, atherosclerotic disease who were(More)
BACKGROUND Blood pressure is an important determinant of the risks of macrovascular and microvascular complications of type 2 diabetes, and guidelines recommend intensive lowering of blood pressure for diabetic patients with hypertension. We assessed the effects of the routine administration of an angiotensin converting enzyme (ACE) inhibitor-diuretic(More)
INTRODUCTION Single-pill combination (SPC) therapy of two drugs is recommended by international guidelines, including the Chinese guidelines (2010), for the treatment of hypertension in high-risk patients who require marked blood pressure (BP) reductions. Real-world data on the efficacy and safety of valsartan/amlodipine (Val/Aml) SPC are scarce. The(More)
Inflammatory mechanisms are important in stroke risk, and genetic variations in components of the inflammatory response have been implicated as risk factors for stroke. We tested the inflammatory gene polymorphisms and their association with ischemic stroke in a Chinese Han population. A total of 1,124 ischemic stroke cases and 1,163 controls were genotyped(More)
The association of a 45-bp insertion/deletion (UCP2-45 bp I/D) polymorphism in uncoupling protein 2 with body mass index (BMI) remains controversial. A case–control study was conducted to examine the association in a Chinese population. The 1,526 subjects recruited in downtown Beijing and genotyped included 616 obese subjects with BMI >28 and 910 age- and(More)
BACKGROUND The contribution of various risk factors to the burden of stroke worldwide is unknown, particularly in countries of low and middle income. We aimed to establish the association of known and emerging risk factors with stroke and its primary subtypes, assess the contribution of these risk factors to the burden of stroke, and explore the differences(More)
BACKGROUND Stroke is a leading cause of death and disability, especially in low-income and middle-income countries. We sought to quantify the importance of potentially modifiable risk factors for stroke in different regions of the world, and in key populations and primary pathological subtypes of stroke. METHODS We completed a standardised international(More)
BACKGROUND Recent genome-wide association (GWA) studies in Caucasians identified multiple single nucleotide polymorphisms (SNPs) associated with coronary artery disease (CAD). The associations of those SNPs with myocardial infarction (MI) have not been replicated in Asian populations. Among those previously identified SNPs, we selected nine (rs10953541,(More)
