Abstract:Objective To study the expression of miR-7 in the peripheral blood of patients with cerebral hemorrhage and its correlation with the recent prognosis.Methods Totally 65 patients with spontaneous intracerebral hemorrhage from March 2015 to March 2019 were selected as the intracerebral hemorrhage group, and 55 healthy volunteers as the control group. The expression of miR-7 in peripheral blood was detected. The short-term prognosis of patients with intracerebral hemorrhage was followed up, and the patients were classified as good prognosis with mRS < 3 and no prognosis with mRS ≥ 3 according to the modified Rankin Scale (mRS) score of 90 days after discharge. The influencing factors of poor prognosis and the predictive value of miR-7 for poor prognosis were analyzed.Results The expression level of miR-7 in the peripheral blood of the cerebral hemorrhage group was significantly lower than that of the control group (P < 0.05); the GCS score, the expression level of miR-7 in the peripheral blood and the proportion of early enteral nutrition of the patients with poor prognosis in the cerebral hemorrhage group were significantly lower than those of the patients with good prognosis (P < 0.05); the random blood glucose, hs-CRP, initial hematoma volume, and the proportion of bleeding into the ventricle were significantly higher than those of the patients with good prognosis (P < 0.05); decreased miR-7 expression, increased random blood glucose, and hs-CRP were the risk factors for poor prognosis, early enteral nutrition was the protective factor for poor prognosis (P < 0.05), and the decreased expression of miR-7 had predictive value for short-term poor prognosis.Conclusion The decreased expression of miR-7 in the peripheral blood of patients with cerebral hemorrhage is a risk factor for poor short-term prognosis and has a predictive value for poor short-term prognosis.
