摘要:

目的 探究血清壳多糖酶3样蛋白1(CHI3L1)、应激诱导蛋白2(Sestrin2)对症状性颈动脉狭窄(SCAS)患者再发缺血性脑卒中(IS)的预测价值。方法 前瞻性纳入82例SCAS患者并根据其是否再发IS分为再发组27例和未再发组55例。超声诊断仪行颈动脉超声检查;酶联免疫吸附法检测血清CHI3L1、Sestrin2水平;收集患者一般资料;Pearson法分析血清CHI3L1、Sestrin2与超声指标的相关性;受试者工作特征曲线分析血清CHI3L1、Sestrin2对SCAS患者再发IS的预测价值。结果 再发组高脂血症比例、重度狭窄比例、CHI3L1水平、Sestrin2水平、动脉狭窄率、时间-强度曲线下面积(AUCTC)、峰值强度均比未再发组高(P<0.05)。血清CHI3L1、Sestrin2与颈动脉狭窄率、AUCTC、峰值强度均呈正相关(r分别为0.496、0.547、0.529、0.489、0.535、0.511,P<0.05)。高CHI3L1、Sestrin2水平SCAS患者再发IS的风险为相应低水平的3.618(95%CI:1.518~8.620)倍、2.591(95%CI:1.232~5.451)倍。血清CHI3L1、Sestrin2单独及联合预测再发IS的曲线下面积(AUC)分别为0.811(95%CI:0.700~0.922)、0.737(95%CI:0.622~0.852)、0.879(95%CI:0.790~0.969),联合预测优于各自单独预测(均P<0.05)。结论 SCAS再发IS患者血清CHI3L1、Sestrin2表达均异常升高,联合检测可提高对SCAS患者再发IS的预测效能。

Abstract:

Objective To explore the predictive value of serum chitinase-3-like protein 1 (CHI3L1) and Sestrin2 for recurrent ischemic stroke (IS) in patients with symptomatic carotid artery stenosis (SCAS). Methods A total of 82 SCAS patients were prospectively enrolled and divided into the recurrence group (27 cases) and the non-recurrence group (55 cases) based on whether they experienced recurrent IS. The ultrasound diagnostic instrument was used to conduct the carotid artery ultrasound examination. Serum CHI3L1 and Sestrin2 levels were detected by ELISA method. General information of patients were collected. Pearson method was used to analyze the correlations between serum CHI3L1, Sestrin2 and ultrasound indicators. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of serum CHI3L1 and Sestrin2 for the recurrence of IS in patients with SCAS. Results The proportion of hyperlipidemia, severe stenosis, levels of CHI3L1 and Sestrin2, arterial stenosis rate, area under the time-intensity curve (AUCTC) and peak intensity were higher in the recurrent group compared to the non-recurrent group (P<0.05). Serum CHI3L1 and Sestrin2 were positively correlated with carotid artery stenosis rate, AUCTC and peak intensity (r=0.496, 0.547, 0.529, 0.489, 0.535, 0.511, P<0.05). The risks of recurrent IS in SCAS patients with high CHI3L1 and Sestrin2 levels were 3.618-fold (95%CI: 1.518-8.620) and 2.591-fold (95%CI: 1.232-5.451), which was higher compared to those with corresponding low levels. The area under the curve (AUC) for serum CHI3L1 and Sestrin2 individually and combined in predicting recurrent IS was 0.811 (95%CI: 0.700-0.922), 0.737 (95%CI: 0.622-0.852) and 0.879 (95%CI: 0.790-0.969), respectively, with the combined prediction being superior to each individual prediction (all P<0.05). Conclusion In SCAS, the serum levels of CHI3L1 and Sestrin2 in patients with recurrent IS are both abnormally elevated, and combined detection can improve the predictive effectiveness for recurrent IS in SCAS patients.
