摘要:

目的 探讨血清胱抑素C(CysC)与单次跨膜糖蛋白147(CD147)对急性缺血性脑卒中(AIS)患者颅内动脉狭窄支架成形术(ICASS)后再狭窄方面的预测价值。方法 选取151例接受ICASS的AIS患者为研究组,同期112例健康体检者为对照组。研究组依据ICASS后6个月内再狭窄情况分为再狭窄组(30例)和未狭窄组(121例)。免疫比浊法检测受试者血清CysC水平;酶联免疫吸附试验检测血清CD147水平;多因素Logistic回归分析AIS患者ICASS后再狭窄的影响因素;受试者工作特征(ROC)曲线评估血清CysC、CD147水平对AIS患者ICASS后再狭窄的预测价值。结果 研究组患者血清CysC、CD147水平较对照组升高(P<0.01);再狭窄组狭窄程度>75%的患者占比、血清CysC、CD147水平均高于未狭窄组(P<0.01);狭窄程度>75%,血清CysC、CD147水平升高是AIS患者ICASS后发生再狭窄的危险因素(P<0.01);ROC曲线分析显示,血清CysC、CD147水平单独预测AIS患者ICASS后再狭窄的曲线下面积(AUC)分别为0.845、0.850,联合预测的AUC为0.942,联合预测效能明显优于单一指标预测(P<0.05)。结论 AIS患者血清CysC、CD147水平升高是ICASS后发生再狭窄的危险因素,两者联合预测ICASS后颅内动脉再狭窄的效能较高。

Abstract:

Objective To explore the application value of serum cystatin C (CysC) and cluster of differentiation 147 (CD147) in predicting restenosis after intracranial artery stenosis stenting (ICASS) in patients with acute ischemic stroke (AIS). Methods A total of 151 AIS patients who received ICASS were selected as the study group, and 112 healthy individuals who underwent physical examinations during the same period were chosen as the control group. The study group was further divided into the restenosis group (30 cases) and the non-stenosis group (121 cases) based on the restenosis status within 6 months after ICASS. The serum CysC levels of the subjects were detected by immunoturbidimetry, and the serum CD147 levels were measured by enzyme-linked immunosorbent assay. Multivariate Logistic regression analysis was conducted to identify factors influencing restenosis after ICASS in AIS patients. The receiver operating characteristic (ROC) curve was used to evaluate the application efficacy of serum CysC and CD147 levels in predicting restenosis after ICASS in AIS patients. Results Serum levels of CysC and CD147 were higher in the study group than those in the control group (P<0.01). The proportion of patients with stenosis degree > 75% and serum levels of CysC and CD147 were higher in the restenosis group than those in the non-stenosis group (P<0.01). The degree of stenosis > 75% and the increased serum levels of CysC and CD147 were risk factors for restenosis after ICASS in AIS patients (P<0.01). ROC curve analysis showed that serum CysC and CD147 levels independently predicted the AUC of AIS patients with restenosis after ICASS were 0.845 and 0.850, respectively, and the combined predicted AUC was 0.942. The combined prediction efficiency was significantly better than that of single indicator prediction (P<0.05). Conclusion The increased levels of serum CysC and CD147 in AIS patients are risk factors for restenosis after ICASS, and the combination of the two is more effective in predicting intracranial artery restenosis after ICASS in AIS patients.
