[摘要] 目的 探討血清氧化型低密度脂蛋白(ox-LDL)、致動(dòng)脈粥樣硬化指數(shù)(AIP)水平與急性腦梗死(ACI)患者頸動(dòng)脈內(nèi)膜中層厚度(CIMT)的關(guān)系。 方法 選擇2016年3~8月重慶市江津區(qū)中心醫(yī)院(以下簡(jiǎn)稱“我院”)神經(jīng)內(nèi)科收治的ACI患者131例(病例組)及同期我院體檢中心的健康成人60例(對(duì)照組)作為研究對(duì)象。采集靜脈血檢測(cè)總膽固醇(TC)、三酰甘油(TG)、低密度脂蛋白膽固醇(LDL-C)、高密度脂蛋白膽固醇(HDL-C)、ox-LDL,并計(jì)算AIP,采用彩色多普勒超聲診斷儀測(cè)量CIMT。 結(jié)果 病例組ox-LDL、AIP、CIMT均高于對(duì)照組(P < 0.05)。相關(guān)性分析顯示ox-LDL與CIMT呈正相關(guān)(r=0.618,P < 0.05),AIP與CIMT呈正相關(guān)(r=0.609,P < 0.05)。 結(jié)論 血清ox-LDL、AIP與ACI患者頸動(dòng)脈內(nèi)膜中層厚度呈正相關(guān),具有預(yù)測(cè)動(dòng)脈狹窄程度的重要意義,臨床上可據(jù)此指導(dǎo)患者積極抗氧化、降脂治療,減少ACI發(fā)病風(fēng)險(xiǎn)。

[Abstract] Objective To investigate the correlation between plasma oxidative low density lipoprotein (ox-LDL), atherogenic index of plasma (AIP) levels and carotid artery intima-media thickness (CIMT) in patients with acute cerebral infarction (ACI). Methods From March to August in 2016, 131 patients with ACI (case group) and 60 healthy people (control group) in Jiangjin Central Hospital were recruited. Venous blood of subjects were collected to detected total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), HDL-C, ox-LDL, and AIP was calculated, and CIMT was measured by color Doppler ultrasonic diagnostic apparatus. Results The ox-LDL, AIP and CIMT in case group were significantly higher than those in control group (P < 0.05). The ox-LDL and AIP were both in positive correlation with the CIMT (r=0.618, 0.609, P < 0.05). Conclusion The ox-LDL and AIP levels in patients with ACI are in positive correlation with the CIMT, it has important significance to predict the extent of arterial stenosis, can help to conduct resist oxidation and lipid-lowering treatment, and reduce the risk of ACI

腦血管病是當(dāng)前我國(guó)主要致死病因之一,每年因此死亡的患者數(shù)量是心血管疾病致死的3倍,并且死亡率仍然以每年30%的速度增長(zhǎng)[1]。有研究顯示我國(guó)每年有200萬(wàn)新發(fā)腦卒中患者,65%為腦缺血導(dǎo)致的,其中超過(guò)50%為動(dòng)脈粥樣硬化(therosclerosis,AS)導(dǎo)致的[2],而AS引起的不穩(wěn)定斑塊破裂繼發(fā)血栓進(jìn)而阻塞腦動(dòng)脈是導(dǎo)致急性腦梗死(acute cerebral infarction,ACI)主要病理生理基礎(chǔ)。在AS的發(fā)展過(guò)程中,動(dòng)脈內(nèi)中膜厚度逐漸增加,導(dǎo)致動(dòng)脈壁形態(tài)改變,尤其頸動(dòng)脈內(nèi)中膜厚度(carotid artery intima-media thickness,CIMT)最典型,被認(rèn)為是AS的危險(xiǎn)因素[3]。此外,作為一種彌漫性血管炎癥性病變,氧化型低密度脂蛋白(oxidative low density lipoprotein,ox-LDL)也被認(rèn)為與AS的發(fā)生發(fā)展密切相關(guān)[4],對(duì)于預(yù)測(cè)和診斷腦血管病具有重要意義。致動(dòng)脈粥樣硬化指數(shù)(atherogenic index of plasma,AIP)是反映血脂代謝的指標(biāo),近年來(lái)研究發(fā)現(xiàn)在糖尿病、冠心病[5-6]等疾病中AIP與CIMT均有較好的相關(guān)性。本研究對(duì)131例ACI患者血漿ox-LDL、AIP進(jìn)行檢測(cè),并分析其與CIMT的關(guān)系,現(xiàn)報(bào)道如下:
