【摘要】目的探讨脑卒中患者颈动脉超声影像特征以及血清学相关指标的变化,并分析二者之间的关系。方法选取112例脑卒中患者作为病例组,选择同期110例健康体检者作为对照组。观察两组患者颈动脉超声影像学指标,并检测血清超敏C反应蛋白(hs-CRP)、同型半胱氨酸(Hcy)以及血尿酸(UA)水平。结果病例组患者斑块检出率(77例,68.75%)、不稳定斑块检出率(31例,27.68%)、颈动脉狭窄发生率(62例,55.36%)以及颈动脉内中膜厚度(IMT)水平(1.21±0.30)mm均高于对照组,差异有统计学意义(P<0.001);病例组患者血清hs-CRP水平为(9.29±2.06)mg/L,Hcy为(15.85±3.59)μmol/L,UA为(420.85±82.90)μmol/L,均高于對照组,差异有统计学意义(P<0001);根据IMT水平的不同,将病例组患者分为颈动脉内膜正常组(39例)、内膜增厚组(50例)以及内膜斑块形成组(23例),内膜增厚组患者血清hs-CRP、Hcy和UA水平均高于内膜正常组,内膜斑块形成组患者上述指标水平均高于内膜正常组和内膜增厚组,差异均有统计学意义(P<0.001)。结论颈动脉超声影像特征对脑卒中的诊断价值较高,并且脑卒中患者hs-CRP、Hcy以及UA等血清学指标也存在异常,与颈动脉IMT存在一定关系,共同参与脑卒中的发生发展过程。

【Abstract】ObjectiveTo investigate the characteristics of carotid ultrasound imaging and the changes of serological indexes in stroke patients,and to analyze the relationship between them.Methods112 stroke patients were selected as case group and 110 healthy persons in the same period as control group.And then,carotid ultrasound imaging parameters were observed,and serum levels of hypersensitive C-reactive protein(hs-CRP),homocysteine(Hcy) and serum uric acid(UA) were measured in both groups.ResultsThe detection rate of plaque(77 cases,68.75%) and unstable plaque(31 cases,2768%),the incidence of carotid artery stenosis(62 cases,55.36%) and carotid intima media thickness(IMT) level(121±0.30)mm in the case group were higher than those in the control group,difference was statistically significant(P<0.001).The serum levels of hs-CRP was (9.29±2.06)mg/L,Hcy was (15.85±3.59)μmol/L,and UA was (420.85±82.90)μmol/L in the case group,all significantly higher than those in the control group,difference was statistically significant(P<0.001).The patients in the case group were divided into normal group(39 cases),intimal thickening group(50 cases) and intimal plaque formation group(23 cases) according to IMT levels.The levels of hs-CRP,Hcy and UA in the intimal thickening group were significantly higher than those in the normal group,and the above indicators in the intimal plaque formation group were significantly higher than those in the normal group and the intimal thickening group,difference was statistically significant(P<0001).ConclusionThe ultrasonic imaging characteristics have a higher diagnostic value for stroke.The serological indexes such as hs-CRP,Hcy and UA are abnormal in patients with stroke,they are related to carotid IMT and participate in the occurrence and development of stroke together.

脑卒中是由于脑血管供血障碍而引起的脑组织损伤的一种急性脑血管疾病,该病病情进展迅速,病死率及致残率均较高,并且近年来脑卒中的发病率呈现持续上升的趋势,不仅对患者的生命健康造成了严重威胁,也增加了家庭和社会的负担,因此早期诊断脑卒中对于预防和治疗均具有重要意义[1]。超声检查在临床中应用极为广泛,在脑卒中的诊断方面也具有重要意义[2],血清学指标检测对于评估脑卒中动脉粥样硬化、脑动脉狭窄的病情和预后具有一定帮助[3]。本研究通过观察脑卒中患者颈动脉超声影像学的特征以及血清学相关指标水平的变化,为更好地辅助脑卒中的诊断和防治提供临床依据。
