巨细胞病毒感染与动脉粥样硬化的临床研究

目的探讨人类巨细胞病毒（ＨＣＭＶ）感染、肿瘤坏死因子（ＴＮＦ）及血浆内皮素（ＥＴ）浓度与动脉粥样硬化的关系。方法采用间接免疫荧光技术测定急性心肌梗塞组（２０例）、冠状动脉狭窄组（２０例）及正常对照组（３０例）血清人类巨细胞病毒抗体，用放射免疫法测定血清ＴＮＦ及ＥＴ的浓度。结果急性心肌梗塞组ＨＣＭＶＩｇＭ阳性１４例（７０％），ＨＣＭＶＩｇＧ阳性２０例（１００％），ＨＣＭＶＩｇＭ、ＩｇＧ双阳性１４例（７０％）；冠状动脉狭窄组ＨＣＭＶＩｇＭ阳性１９例（９５％），ＨＣＭＶＩｇＧ阳性１９例（９５％），ＩｇＭ、ＩｇＧ双阳性１８例（９０％）；正常对照组ＨＣＭＶＩｇＭ阳性６例（２０％），ＨＣＭＶＩｇＧ阳性２６例（８２％），ＩｇＭ、ＩｇＧ双阳性６例（２０％），与正常对照组比较，差异有显著性（Ｐ＜０００１，Ｐ＜００５，Ｐ＜０００１）；冠心病急性心肌梗塞组、冠状动脉狭窄组与正常对照组相比，血清ＴＮＦ、血浆ＥＴ显著增高（Ｐ＜０００１）。结论患者的ＨＣＭＶ感染、内皮细胞受损和ＴＮＦ作用可能参与了冠心病发生发展的过程。

Cytomegalovirus infection, tumor necrosis factor, endothelin and coronary heart disease

Objective To investigate the relationship between human cytomegalovirus (HCMV) infection, tumor necrosis factor (TNF), endothelin (ET) in patients with coronary heart disease Methods Blood samples were collected from 20 acute myocardial infarction patients, 20 coronary artery stenosis patients and 30 controls Serum anti HCMV antibody was determined by indirect immunofluorescence technique; serum TNF and plasma ET by radioimmunoassay Results Positive HCMVIgM and HCMVIgG were found in 14 (70%) and 20 cases (100%) respectively in the 20 patients with acute myocardial infraction;19(95%) and 19 cases (95%) in the 20 patients with coronary artery stenosis; 6(20%) and 26 cases (82%) in the 30 controls Concentrations of serum TNF and plasma ET in the acute myocardial infarction or coronary artery stenosis group were significantly higher (all P<0001) than those in the control group Conclusion HCMV infection, TNF, ET might be implicated in the pathogenesis of coronary heart disease
