Expression and short-term prognostic value of miR-126 and miR-182 in patients with acute stroke

Expression and short-term prognostic value of miR-126 and miR-182 in patients with acute stroke were investigated. In total, 153 patients with acute stroke admitted to the Second Affiliated Hospital of Soochow University from February 2016 to February 2018 were enrolled into the observation group as group A [88 patients with acute cerebral infarction (AIS)] or group B [65 patients with cerebral hemorrhage (ICH)]. Furthermore, 69 healthy people receiving physical examinations in the hospital were enrolled into the control group. The relative expression of miR-126 and miR-182 in all subjects were measured and their correlation with the National Institute of Health stroke scale (NIHSS) and activities of daily living (ADL) scores was analyzed. After 3 months of follow-up, the correlation of miR-126 and miR-182 with the Modified Rankin Scale (MRS) score of patients was investigated. The receiver operating characteristic (ROC) curve was employed to explore the value of miR-126 and miR-182, alone or in combination, in predicting the prognosis of acute stroke patients. Subjects in the control group had markedly higher miR-126 expression and lower miR-182 expression than those in group A and group B in the observation group (P<0.05). Pearson's correlation analysis suggested a notable correlation of miR-126 and miR-182 with NIHSS and ADL scores. Patients with a mild condition or good prognosis had higher miR-126 expression and lower miR-182 expression than patients with a severe condition or poor prognosis (P<0.05). Both miR-126 and miR-182 predicted the prognosis of acute stroke, and the combination of miR-126 and miR-182 presented better accuracy. The expression levels of miR-126 and miR-182 are associated with the neurological function, self-care ability, and prognosis in patients with acute stroke is highly valuable for predicting the prognosis of patients.
