摘要:
目的 探讨血管细胞黏附因子-1(VCAM-1)联合Fazekas评分对合并脑白质疏松的急性脑梗死(ACIL)患者发病后90 d转归的预测价值。 方法 选取2020年8月—2021年10月安徽医科大学附属宿州医院收治的首次发病NIHSS评分为8分的ACIL患者96例为研究对象。采用酶联免疫吸附法(ELISA)检测血清VCAM-1水平,并对ACIL患者进行Fazekas评分。根据改良的Rankin量表(mRS)评价患者发病后90 d的预后情况,mRS≤2分为预后良好(70例),mRS≥3分为预后不良(26例)。采用ROC曲线分析血清VCAM-1联合Fazekas评分对ACIL患者预后的评估价值。 结果 与预后良好组比较,预后不良组患者年龄[(71.23±3.66)岁vs.(64.57±5.24)岁]、血清VCAM-1[2.66(2.48,2.78)ng/mL vs. 2.10(1.40,2.23)ng/mL]、Fazekas评分[4(4,5)分vs. 3(2,3)分]显著升高(均P<0.05)。多因素logistic回归分析显示年龄大、VCAM-1升高及Fazekas评分升高是预后不良的独立危险因素。ROC曲线分析结果显示血清VCAM-1联合Fazekas评分评估预后不良的灵敏度为92.31%,特异度为94.29%。 结论 血清VCAM-1联合Fazekas评分对ACIL患者发病后90 d转归具有较高的预测价值。 -

Abstract:Objective To explore the predictive value of serum vascular cell adhesion molecule 1 (VCAM-1) level combined with Fazekas score in the clinical outcome of acute cerebral infarction with leukoaraiosis (ACIL) patients after 90 days. Methods A total of 96 acute cerebral infarction patients with an National Institutes of Health Stroke Scale (NIHSS) score of 8 who were admitted to the Suzhou Hospital Affiliated to Anhui Medical University from August 2020 to October 2021 were selected as the research objects. Enzyme-linked immunosorbent assay was used to detect serum VCAM-1 levels, and Fazekas score was determined for all patients according to brain magnetic resonance. Based on the modified Rankin scale (mRS), the prognosis of patients at 90 days was evaluated. mRS≤2 was regarded as good prognosis (70 cases), and mRS≥3 was regarded as poor prognosis (26 cases). The receiver operating characteristic (ROC) curve was used to analyse the value of serum VCAM-1 level combined with Fazekas score in evaluating the prognosis of ACIL patients. Results Compared with the good-prognosis group, the age [(71.23±3.66) years vs. (64.57±5.24) years], serum VCAM-1 level [2.66 (2.48, 2.78) ng/mL vs. 2.10 (1.40, 2.23) ng/mL], and Fazekas score [4 (4, 5) points vs. 3 (2, 3) points] of the poor-prognosis group were significantly higher than those in the good-prognosis group (all P < 0.05). Multivariate logistic-regression analysis showed that age, VCAM-1 level and Fazekas score were independent risk factors for poor prognosis. ROC curve analysis results revealed that the sensitivity and specificity of poor prognosis assessment were 92.31% and 94.29%, respectively. Conclusion Serum VCAM-1 combined with Fazekas score has a high predictive value for the 90-day outcome of acute cerebral infarction patients. -
