Clinical significance of miR-126 in prognosis of cerebral infarction after thrombectomy
Objective To detect the changes of serum microRNA-126(miR-126)before interventional thrombectomy for acute cerebral infarction,and to explore its correlation with the prognosis of patients.Methods A retrospective analysis was performed on 101 patients with cerebral infarction who underwent interventional thrombectomy in he First People's Hospital of Huzhou from January 2019 to December 2021.The patients were followed up for 2 month.According to modified Rankin scale(mRS),they were divided into good prognosis group(mRS≤2 points,56 cases)and poor prognosis group(mRS>2 points,45 cases).The clinical data of two groups and the difference of miR-126 before thrombectomy were compared,and the effect of serum miR-126 change on the prognosis of patients with cerebral infarction was analyzed.Results The serum miR-126 level before thromrectomy in good prognosis group was significantly higher than that in poor prognosis group[(9.31±2.14)vs.(1.36±0.28),P<0.01].There was a negative correlation between miR-126 and National Institute of Health stroke scale(NIHSS)score(r=-0.737,P<0.01),and a positive correlation between miR-126 and good collateral circulation(r=0.645,P<0.01).The area under the receiver operating characteristic curve for establishing miR-126 to predict prognosis after thrombolectomy for cerebral infarction was 0.818.The sensitivity and specificity were 78.9%and 86.0%at the optimal cut-off value.Conclusion The change of serum miR-126 level before thrombectomy may be related to the prognosis of patients with cerebral infarction,which can be used as a marker to predict the prognosis of cerebral infarction after interventional therapy.
