Abstract:
Objective To investigate the relationship between serum microRNA(miRNA,miR)-9-5p,miR-21-5p and miR-206 and hemorrhagic transformation(HT)occurs and prognosis in patients with large ar-tery atherosclerotic cerebral infarction(ACI-LAA)after thrombolysis.Methods A total of 265 patients with ACI-LAA admitted to the hospital from April 2021 to November 2023 were selected as the research objects.According to whether HT occurred after intravenous thrombolysis,they were divided into non-HT group and HT group,and the expression levels of serum miR-9-5p,miR-21-5p and miR-206 were compared between the two groups.The general data of patients with ACI-LAA were collected.Univariate and multivariate Logistic regression analysis were used to analyze the influencing factors of HT occurs in patients with ACI-LAA after thrombolysis.The receiver operating characteristic(ROC)curve was used to analyze the efficacy of serum miR-9-5p,miR-21-5p and miR-206 expression levels in predicting HT occurs after thrombolysis in patients with ACI-LAA.The patients with ACI-LAA were followed up for 90 d.According to the modified Rankin scale(mRS)score,the patients were divided into a good prognosis group and a poor prognosis group,and the expression levels of serum miR-9-5p,miR-21-5p and miR-206 were compared between the two groups.Univa-riate and multivariate Logistic regression analysis were used to analyze the influencing factors of poor progno-sis in patients with ACI-LAA.ROC curve was used to analyze the efficacy of serum miR-9-5p,miR-21-5p and miR-206 expression levels in predicting poor prognosis of patients with ACI-LAA.Results HT occurred in 74(27.92％)of 265 patients with ACI-LAA after thrombolysis.Compared with the non-HT group,the National Institutes of Health Stroke Scale(NIHSS)score atadmission,the proportion of hypertension,the proportion of infarct size ≥10 cm2,and the expression levels of serum miR-21-5p and miR-206 were significantly in-creased in the HT group(P＜0.05).However,the expression level of serum miR-9-5p was decreased(P＜0.05).Hypertension,high NIHSS score at admission,the proportion of infarct size ≥10 cm2,high expression of miR-21-5p and miR-206 were risk factors for HT occurs in patients with ACI-LAA after intravenous thrombolysis,and high expression of miR-9-5p was a protective factor(P＜0.05).The ROC curve showed that the area under the curve(AUC)and 95％CI of single and combined detection of serum miR-9-5p,miR-21-5p and miR-206 for predicting HT occurs were 0.796(0.726-0.866),0.779(0.711-0.846),0.784(0.714-0.854),0.891(0.839-0.943),respectively.Among 265 patients with ACI-LAA,83 patients(31.32％)had poor prognosis at 90 d of follow-up.Compared with the good prognosis group,the age,NIHSS score at admis-sion,the proportion of HT,the proportion of infarct size ≥10 cm2,and the expression levels of serum miR-21-5p and miR-206 were increased(P＜0.05),and the expression level of serum miR-9-5p was decreased(P＜0.05)in the poor prognosis group.Advanced age,high NIHSS score at admission,HT,infarct size ≥10 cm2,high expression of miR-21-5p,and high expression of miR-206 were risk factors for poor prognosis of ACI-LAA patients,and high expression of miR-9-5p was a protective factor(P＜0.05).The ROC curve showed that The AUC(95％CI)of single and combined detection of serum miR-9-5p,miR-21-5p and miR-206 for predicting poor prognosis were 0.754(0.691-0.818),0.779(0.719-0.838),0.792(0.815-0.919),0.931(0.902-0.960),respectively.Conclusion Low expression of serum miR-9-5p,high expression of miR-21-5p and high expression of miR-206 are associated with the HT occurs and poor prognosis in patients with ACI-LAA after thrombolysis,and the combined detection of the three indicators has a high predictive value for the HT occurs and poor prognosis.
