目的 探讨我国浙江地区汉族人群基质金属蛋白酶-8 (matrix metalloproteinase-8,MMP-8)启动子基因-799C/T多态与颈动脉斑块易损性的关系.方法 451例脑梗死患者根据颈动脉超声分为易损斑块组(共135例)和稳定斑块组(共316例).采用酶联免疫吸附法测定两组血清MMP-8水平,并采用聚合酶链反应-限制性片段长度多态性方法分析两组MMP-8启动子基因-799C/T多态的基因型.结果 易损斑块组发病48 h内血清MMP-8水平为(0.86±0.16)ng/μL,稳定斑块组为(0.80±0.13) ng/μL,两者差异有统计学意义(t=2.894,P=0.004).易损斑块组CT+ TT基因型频率为73.3%,稳定斑块组为54.7%,两者差异有统计学意义(x2=13.65,P=0.000);T等位基因频率在易损斑块组为48.1%,在稳定斑块组为33.5%,两者差异有统计学意义(x2=17.14,P=0.000).CC基因型组血清MMP-8水平为(0.79±0.13) ng/μL,TT基因型组血清MMP-8水平为(0.92±0.11) ng/μL,两者比较差异有统计学意义(t=3.141,P=0.001).结论 MMP-8启动子基因-799C/T多态可能与浙江地区汉族人颈动脉易损斑块发生的倾向有关,T等位基因可能是颈动脉斑块易损的遗传易患性标志之一.
目的 探討我國浙江地區漢族人群基質金屬蛋白酶-8 (matrix metalloproteinase-8,MMP-8)啟動子基因-799C/T多態與頸動脈斑塊易損性的關繫.方法 451例腦梗死患者根據頸動脈超聲分為易損斑塊組(共135例)和穩定斑塊組(共316例).採用酶聯免疫吸附法測定兩組血清MMP-8水平,併採用聚閤酶鏈反應-限製性片段長度多態性方法分析兩組MMP-8啟動子基因-799C/T多態的基因型.結果 易損斑塊組髮病48 h內血清MMP-8水平為(0.86±0.16)ng/μL,穩定斑塊組為(0.80±0.13) ng/μL,兩者差異有統計學意義(t=2.894,P=0.004).易損斑塊組CT+ TT基因型頻率為73.3%,穩定斑塊組為54.7%,兩者差異有統計學意義(x2=13.65,P=0.000);T等位基因頻率在易損斑塊組為48.1%,在穩定斑塊組為33.5%,兩者差異有統計學意義(x2=17.14,P=0.000).CC基因型組血清MMP-8水平為(0.79±0.13) ng/μL,TT基因型組血清MMP-8水平為(0.92±0.11) ng/μL,兩者比較差異有統計學意義(t=3.141,P=0.001).結論 MMP-8啟動子基因-799C/T多態可能與浙江地區漢族人頸動脈易損斑塊髮生的傾嚮有關,T等位基因可能是頸動脈斑塊易損的遺傳易患性標誌之一.

Objective To investigate the association between a -799C/T polymorphism in the promotor region of matrix metalloproteinase-8 (MMP-8)gene and instability of carotid plaque in Chinese Han population.Methods A total of 451 acute infarction patients from the Department of Neurology of Taizhou Hospital were divided into carotid vulnerable plaque group and carotid stable plaque group according to the results of carotid B-mode ultrasonography. Serum MMP-8 level was measured by the means of enzyme-linked immunosorbent assay (ELISA).At the same time,the MMP-8 -799C/T polymorphism was determined by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.Results Serum level of MMP-8 in the carotid vulnerable plaque group was higher than that in the carotid stable plaque group (t=2.894,P=0.004).The genotype distribution of -799C/T polymorphism between the two groups was significantly different (x2 =13.65,P=0.000).Serum level of MMP-8 in patients with TT genotype was higher than that in patients with CC genotype (t=3.141,P=0.001).Conclusion The present study suggested that serum level of MMP-8 and the - 799C/T polymorphism of MMP-8 gene are associated with carotid vulnerable plaque in Chinese Han population,and the T allele may be a predictor for the susceptibility of carotid vulnerable plaque.
