MMP-9、NLR值对急性缺血性卒中血运重建后出血转化的预测价值

The Predictive Value of MMP-9 the and NLR Values for Bleeding Transformation after the Revascularization in Acute Ischemic Stroke

目的研究急性缺血性卒中(acute ischemic stroke, AIS)血运重建前后金属基质蛋白酶9(matrixmetalloproteinase-9,MMP-9)、中性粒细胞/淋巴细胞比值(NLR值)的变化与出血转化的相关性,以期寻找预测AIS患者血运重建后出血转化的生物标记物。方法 收集2022年2月至2022年12月曲靖市第一人民医院卒中中心收治的AIS并接受血运重建治疗(静脉溶栓、血管内治疗、同时接受静脉溶栓和血管内治疗)的患者161例,其中出血转化组46例,非出血转化组115例,通过比较血运重建后出血转化组与非出血转化组的一般信息、血运重建前后NLR值及MMP-9等指标。结果 2组患者一般资料对比,除C反应蛋白存在差异外(P <0.001),余临床资料对比差异无统计学意义(P> 0.05),出血转化组在治疗前白细胞、中性粒细胞、中性粒细胞百分比、中性粒细胞绝对值、淋巴细胞绝对值、NLR、MMP-9较非出血转化明显升高,差异有统计学意义(P <0.05),血运重建后血常规各项指标、MMP-9较血运重建前明显升高,出血转化组较非出血转化组升高更加明显,差异有统计学意义(均P <0.001),ROC曲线示NLR、MMP-9预测AIS血运重建后出血转化的曲线下面积(AUC)为0.74、0.90。结论 NLR、MMP-9与AIS患者血运重建后出血转化发病风险相关,可作为出血转化风险预测因子。

Objective To study the correlation between the changes of matrix metalloproteinase-9(MMP-9)and neutrophil/lymphocyte ratio(NLR)before and after the revascularization of acute ischemic stroke(AIS),so as to find biomarkers to predict the bleeding transformation risk of AIS patients.Methods From February 2022 to December 2022,161 patients admitted to the Stroke Center of Qujing Hospital Affiliated to Kunming Medical University with AIS werre divided in to the hemorrhagic transformation group and the non-hemorrhagic transfor-mation groupand treated with revascularization(intravenous thrombolysis,endovascular treatment,combined the intravenous thrombolysis with endovascular treatment).Among them,there were 46 cases in the hemorrhagic transformation group and 115 cases in the non hemorrhagic transformation group.And the general data,NLR value and MMP-9 before and after the revascularization were compared between the two groups.Results There was no statistical difference in general data between the two groups(all P>0.05)except for C-reactive protein in hemorrhagic transformation group and in non-hemorrhagic transformation group(P<0.001).The white blood cells,neutrophils,neutrophil percentage,neutrophil absolute value,lymphocyte absolute value,NLR and MMP-9 value in hemorrhagic transformation group were significantly higher than those in non-hemorrhagic transformation group before the treatment and there was a statistical significance(P<0.05).After revascularization,the indexes of blood routine and MMP-9 were significantly higher than those before the revascularization,and the increase in hemorrhagic transformation group was more obvious than that in non-hemorrhagic transformation group and there was a statistical significance(P<0.001),The ROC curve showed that the area under the curve(AUC)of NLR and MMP-9 predicting bleeding transformation after AIS revascularization were 0.74 and 0.90.Conclusion NLR,MMP-9 are associated with the risk of bleeding transformation in AIS patients after the revascularization and can they can be used as the predictive factors for bleeding transformation risk.
