BackgroundSome microRNAs have been found to be abnormal in patients with acute cerebral infarction (ACI) after intravenous thrombolysis. This study aimed to measure the expression of miR-106a-5p in ACI patients before and after thrombolytic treatment, and to investigate the prognostic value of miR-106a-5p and computed tomography perfusion imaging (CTPI) parameters in ACI patients receiving thrombolysis.MethodsThe levels of serum miR-106a-5p were detected by quantitative real-time PCR in 78 ACI patients before thrombolysis, 24 hours after thrombolysis, and 3 months (90 days) after onset. The correlation of miR-106a-5p with continuous variables were analyzed using Pearson correlation analysis. The association of miR-106a-5p and CTPI parameters with prognosis of patients receiving thrombolysis was evaluated by logistic regression analysis. The accuracy and thresholds of miR-106a-5p and CTPI parameters for discriminating patients with unfavorable prognosis after thrombolysis were assessed by receiver operating characteristic analysis.ResultsSerum miR-106a-5p expression was decreased in ACI patient after thrombolysis. Then, significant correlations of miR-106a-5p with National Institutes of Health Stroke Scale and CTPI parameters were found. Moreover, miR-106a-5p, cerebral blood flow (CBF) and cerebral blood volume (CBV), which are 2 CTPI parameters, were independently correlated with short- and long-term prognosis after thrombolysis. Furthermore, miR-106a-5p, CBF and CBV revealed good accuracy in predicting the prognosis of patients after thrombolysis, and their combination showed the best accuracy.ConclusionThrombolysis downregulates miR-106a-5p in ACI patients, and miR-106a-5p, CBF and CBV have considerable potentials to predict short- and long-term prognosis in ACI patients receiving intravenous thrombolysis.Copyright © 2023 the Author(s).
