The results of studies on association between CTLA-4 exon-1 +49A/G (rs231775) polymorphism and susceptibility to systemic lupus erythematosus are controversial. To derive a more precise estimation of the relationship between the CTLA-4 exon-1 +49A/G polymorphism and SLE, a meta-analysis of 18 published case–control studies was performed. 18 studies meeting(More)
Polymorphisms in the endothelial nitric oxide synthase (eNOS) gene may influence the risk of ischemic stroke (IS), but the results are still debatable. A meta-analysis was performed to investigate the association between the eNOS gene polymorphisms in IS risk. Case-control studies on the association between the G894T, T-786C, and 4b/a polymorphisms and IS(More)
BACKGROUND The government of China promulgated new medical care reform policies in March 2009. After that, provincial-level governments launched new medical care reform which focusing on local comprehensive medical care reform (LCMR). Anhui Province is an example of an area affected by LCMR, in which the LCMR was started in October 2009 and implemented in(More)
Obesity is a risk of cardiovascular diseases. Our previous studies revealed that serum calcium level may have influence in the blood pressure to older male subjects. The aim of this study was to evaluate the relationship between total serum calcium level and overweight and obesity subjects. In our study, overweight and obesity status and total serum calcium(More)
OBJECTIVE The results of studies on association between TGF-beta1 T869C polymorphism and susceptibility to RA are controversial. The absence of a replication of linkage might be due to different ethnicities. The aim of this study was to perform a preliminary investigation on the effect size of TGF-beta1 T869C polymorphism on RA susceptibility through a(More)
The association between transforming growth factor-β1 (TGF-β1) gene polymorphisms and Alzheimer’s disease (AD) risk has been widely reported, but results were somewhat controversial and underpowered. To derive a more precise estimation of the relationship between TGF-β1 polymorphisms and AD risk, we conducted a meta-analysis of all available case–control(More)
To derive a more precise estimation of the relationship between TGF-β1 polymorphisms and gastric cancer (GC) risk, we conducted a meta-analysis of all available case–control studies relating the C-509 T, T869C, and G 915C polymorphisms of the TGF-β1 gene to the risk of developing GC. The effect summary odds ratio (OR) and 95 % confidence intervals (CIs)(More)
The results of studies on association between the C677T polymorphism of the 5,10-methylene-tetrahydrofolate reductase (MTHFR) gene and osteonecrosis of the femoral head (ONFH) are controversial. To derive a more precise estimation of the relationship between the MTHFR C677T polymorphism and ONFH, a meta-analysis was performed. Eight studies on MTHFR C677T(More)
The association between methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and diabetic nephropathy (DN) or diabetes mellitus (DM) risk has been widely reported, but the results are still debatable. To investigate the role of MTHFR C677T polymorphism on DM or DN, 13 separate studies in the Chinese population on the relation between MTHFR C677T(More)
