急性脑梗死患者血清CXCL16水平与卒中亚型的关系

目的 探讨急性脑梗死患者血清CXCL16水平变化及其与脑梗死TOAST病因学分型之间的关系.方法 应用酶联免疫吸附法检测113例急性脑梗死患者血清CXCL16水平,按TOAST分型进行分组,将各亚组之间以及与32例健康对照者进行比较.结果 病例组血清CXCL16水平显著高于对照组(2.29±0.21)ng/ml对(1.75±0.21)ng/ml,t=12.863,P=0.000];大动脉粥样硬化性卒中组血清CXCL16水平显著高于小动脉闭塞性卒中组(2.38±0.23)ng/ml对(2.21±0.11)ng/ml,q=5.743,P=0.000],而且两者均显著高于对照组(q=20.501,P=0.000;q=13.527,P=0.000).在大动脉粥样硬化性卒中组中,≥2条动脉狭窄组血清CXCL16水平与仅有1条动脉狭窄组无显著差异(2.34±0.24)ng/ml对(2.46±0.19)ng/ml,t=-1.969,P=0.054].多变量logistic回归分析显示,CXCL16(OR=0.972,95% CI 0.956～0.978,P=0.001)和高脂血症(OR=3.547,95% CI1.160～10.848,P=0.020)足脑梗死发生的独立危险因素.结论 血清CXCL16水平在脑梗死急性期升高,与脑梗死发生密切相关,且大动脉粥样硬化性卒中组显著高于小动脉闭塞性卒中组.

Relationship between serum CXCL16 levels and stroke subtypes in patients with acute cerebral infarction

Objective To investigate the changes of serum CXCL16 levels in patients with acute cerebral infarction and their relationship with the Trial of Org10172 in Acute Stroke Treatment (TOAST) etiological types of cerebral infarction. Methods The serum CXCL16 levels in 113 patients with acute cerebral infarction were measured by enzyme-linked immunosorbent assay (ELISA), and they were grouped according to TOAST types. The patients between all the subgroups and/or 32 healthy controls were compared. Results The serum CXCL16 levels in patient group were significantly higher than those in control group (2.29 ± 0.21 ng/mlvs.1.75±0.21 ng/ml, t= 12.863, P= 0.000); The serum CXCL16 levels in large artery atherosclerotic (LAA) stroke group were significantly higher than those in small artery occlusive (SAO) stroke group (2.38 ±0.23 ng/mL vs. 2.21 ±0.11 ng/ml, 1 =5. 743, P =0. 000), and both were significantly higher than those in the control group (q = 20. 501, P = 0. 000; q =13. 527, P= 0. 000). In the LAA group, there were no significant differences between the serum CXCL16 levels in ≥2 artery stenosis group and those in only 1 artery stenosis group (2.34 ±0.24 ng/ml vs. 2.46 ± 0. 19 ng/ml, t = - 1.969, P = 0. 054). Multivariate logistic regression analysis showed that CXCL16 (OR =0.972, 95% CI0.956-0. 978, P =0.001)and hyperlipidemia (OR =3.547, 95%CI 1.160-10. 848, P=0. 020) were the independent risk factors for cerebral infarction. Conclusions The serum CXCL16 levels increased in acute cerebral infarction, it closely related with the occurrence of cerebral infarction, and the LAA stroke group was significantly higher than the SAO stroke group.
