Abstract
動脈粥狀硬化是一個牽涉發炎反應和血管重建的緩慢過程,也是腦血管疾病、心血管疾病與周邊血管性疾病的主要次臨床症狀。本研究主要探討基質金屬蛋白酵素-1, -3, -9 (matrix metalloproteinase-1, -3, -9, MMP-1, -3, -9) 的基因多形性及其活化態酵素表現對於頸動脈粥狀硬化的獨立與交互作用之相關。利用國民健康局於民國92年到94年所補助之「臺北醫學大學文山區中風防治中心先驅性研究計畫」,該計劃於民國93年在士林區建立三十歲以上社區居民的追蹤世代,其中433位民眾受邀並接受頸部超音波檢查,以此作為研究樣本,依研究對象頸動脈內中膜層厚度 (intimal media thickness, IMT) 之中位?0.7 mm作為切點,將IMT ≦ 0.7 mm者作為對照組,IMT > 0.7 mm或頸動脈硬化者為個案組,藉由動脈粥狀硬化指標進行MMP-1, -3, -9之基因型與活化態酵素表現分析。利用標準化問卷與流程收集研究對象之基本人口學資料並抽取禁食後八小時靜脈血測量其生化?。將萃取出的DNA利用聚合?連鎖反應 (polymerase chain reaction, PCR) 與限制片段長度多形性 (restriction fragment length polymorphism, RFLP) 方式來進行各基因型判定;用酵素連結免疫分析法(enzyme-linked immunosorbent assay, ELISA) 方式來進行活化態酵素表現分析。結果顯示年齡、高血壓、脂質異常、肥胖、禁食後血糖、Chol/HDL-C比值與LDL/HDL-C比值為動脈粥狀硬化的重要預測因子。調整年齡和性別後,對照組與個案組在各生化?有顯著差異。基因型方面,合併MMP-1, -3, -9危險基因數後,隨危險基因數的增加,IMT增厚或頸動脈硬化的危險性提高。表現型方面,Chol/HDL-C比值低者,MMP-1, -3, -9隨著濃度的增加其IMT增厚或頸動脈硬化的危險性降低。而MMP-3則觀察到男性表現量為女性的兩倍,達統計上顯著差異。
