  • Association between Plasma Homocysteine Level and the Prevalence of Coronary Heart Disease: A Meta-analysis

    Objective To evaluate the association between coronary heart disease (CHD) and plasma homocysteine level, and to provide additional information for prevention and management of CHD. Methods We searched CBM, CNKI, WanFang, and VIP databases. Case-control studies about the association between CHD and plasma homocysteine level published in China were identified. Meta-analysis was performed using RevMan 4.2 software. Results The result of meta-analysis showed the plasma homocysteine level in the CHD group was higher than that of the control group (WMD=4.88, 95%CI 4.40 to 5.35, Plt;0.000 01), and the loss of safety coefficient was 1 339. Conclusion High plasma homocysteine level is associated with increasing morbidity of CHD.

  • Mosaic adeno-associated virus-mediated gene transfer of calcitonin gene-related peptide for prevention of inflammatory mediator expression, macrophage infiltration and neointimal hyperplasia in an experimental rabbit vein graft model

    Objective To investigate the effect and mechanism of calcitonin gene-related peptide (CGRP) on the prevention and treatment of transplant vein graft disease. Methods The 25 New Zealand white rabbits were divided into three groups: an experimental group [n=8, the rabbit jugular veins transfected with adeno-associated virus vector tipe 2/1 containing CGRP gene (AAV2/1-CGRP)], a carrier group [n=9, transfected with mosaic adeno-associated virus vector tipe 2/1 containing LacZ gene (AAV2/1-LacZ)] and a control group (n=8, saline) and then the cervical veins were implantated into the ipsilateral carotid artery by reverse end-side anastomosis. At 4 weeks after surgery, the pathology of the specimens, CD68 immunohistochemistry, in situ β-galactosidase staining were obtained. The expression of CGRP gene was detected by reverse transcription-polymerase chain reaction (RT-PCR). Monocyte chemoattractant protein-1(MCP-1), tumour necrosis factor-α (TNF-α), inducible nitric oxide synthase (iNOS) and matrix metalloproteinase-9 (MMP-9) were detected by real-time polymerase chain reaction (real-time PCR). Results The CGRP and LacZ gene expression was positive at postoperative 4 weeks. The intima/media ratio was significantly inhibited in the experimental group. Macrophage infiltration and expression of inflammatory mediators including MCP-1, TNF-α, iNOS and MMP-9 were also significantly inhibited in the experimental group. Conclusion Transfection of AAV2/1-CGRP inhibits inflammatory mediator expression, macrophage infiltration and neointimal hyperplasia in experimental vein graft disease.
