血清乳凝集素、唾液酸与冠心病的相关性研究

摘要

Objective To study the relationship between serum lactadherin (MFG-E8),sialic acid (SA) level and coronary heart disease (CHD) occurrence and development.Methods 166 patients in our hospital were selected from June 2014 to November 2015,and then according to the result of coronary angiography divide the subjects into control group (n=56,the result of coronary angiography completely normal) and CHD group,including stable angina 48 cases (StA subgroup),unstable angina 30 cases (UA subgroup) and acute myocardial infarction 32 cases (AMI subgroup).The serum level of MFG-E8 was detected by ELISA method,the serum level of SA,hs-CRP and lipid index were detected by biochemical analysis.Gensini score showed the severity of coronary stenosis.The correlation analysis between detecting parameters was carried out by Spearman method.Results Compared with the control group,the patients with CHD have a higher level of serum SA and a lower level of MFG-E8 (both P<0.05).The AMI subgroup has a lower level of serum MFG-E8 than StA and UA subgroups,and the AMI subgroup has a higher level of serum SA than StA and UA subgroups (all P<0.05).The correlation analysis showed that the serum SA has a positively correlation with the level of TG,hs-CRP,and Gensini score,and has a negatively correlated with the level of MFG-E8 (all P<0.05).The MFG-E8 has a negatively correlated with the level of TG,hs-CRP,and Gensini score (all P<0.05).Conclusion MFG-E8 and SA play an important role in the development of CHD,and combined detection of serum MFG-E8 and SA may be helpful in the clinical diagnosis and risk assessment of patients with CHD.%目的 探讨血清乳凝集素(MFG-E8)、唾液酸(SA)水平与冠状动脉粥样硬化性心脏病(CHD)发生发展的关系.方法 将2014年6月至2015年11月该院心内科收住的166例住院患者纳入研究,其中56例冠状动脉造影结果完全正常者作为对照组,另110例诊断为CHD的患者作为CHD组.CHD组根据临床诊断分为稳定型心绞痛(StA)组、不稳定型心绞痛(UA)组以及急性心肌梗死(AMI)组.采用酶联免疫吸附测定(ELISA)法测定血清MFG-E8水平,使用生化分析检测血清SA、超敏C反应蛋白(hs-CRP)及血脂水平,Gensini评分表示冠状动脉狭窄程度,各检测指标间进行Spearman相关分析.结果 与对照组相比,CHD组患者血清MFG-E8水平明显降低,SA水平显著升高(均P<0.05);AMI亚组MFG-E8显著低于StA和UA亚组,AMI亚组SA显著高于StA和UA亚组(均P<0.05).相关性分析表明,血清MFG-E8水平与TG、hs-CRP水平及Gensini评分呈负相关(均P<0.05),SA水平与TG、hs-CRP水平及Gensini评分呈正相关,与MFG-E8水平呈负相关(均P<0.05).结论 MFG-E8、SA与CHD发生发展有关,联合检测血清MFG-E8、SA水平可能有助于CHD的临床诊断和风险评估.
