ABSTRACT
Objective:To explore the correlation between serum microRNA(miR)-124 and miR-181c expression and the treatment outcome of Solitaire stent thrombectomy in patients with acute cerebral infarction and its influencing factors.Methods:Eighty-one patients with acute cerebral infarction performed Solitaire stent thrombectomyfrom June 2018 to October 2020 in the Affiliated Hospital of Jining Medical College were selected. The predictive value of miR-124, miR-181c expression in patients with acute cerebral infarction were analyzed.Results:In 81 patients, 21 patients with poor outcome(poor outcome group) and 60 patients with favorable outcome (favorable outcome group). The ratio of age ≥ 60 years in poor outcome group was higher than that in the favorable outcome group: 76.19% (16/21) vs. 46.67% (28/60), there was statistical difference ( χ2 = 5.46, P<0.05). The levels of miR-124, miR-181c before surgery and postoperative 1-day, 7-day in the favorable outcome group were higher than those in poor outcome group: 2.81 ± 0.82 vs. 2.24 ± 0.74, 3.01 ± 1.52 vs. 2.07 ± 1.04, 3.25 ± 1.67 vs. 1.86 ± 0.92; and the levels of miR-181c before surgery and postoperative 1-day, 7-day in the favorable outcome group were lower than those in the poor outcome group: 1.43 ± 0.59 vs. 1.79 ± 0.65, 1.35 ± 0.62 vs. 1.94 ± 0.79, 1.24 ± 0.60 vs. 2.16 ± 1.08, there were statistical differences ( P<0.05). The results of Logistic multivariate analysis showed that the age, the levels of miR-124, miR-181c before operation and postoperative 1-day, 7-day were influencing factors for the treatment outcome of Solitaire stent thrombectomy. The receiver operating characteristic (ROC) curve analysis showed that the area under the curve of miR-124, miR-181c on the postoperative 7-day were 0.806, 0.861, and were higher than those before operation and the postoperative 1-day, the diagnostic sensitivity were 71.43%, 76.19%, the specificity were 88.33%, 85.00%. Conclusions:The expression of miR-124 and miR-181c in the serum of acute cerebral infarction is related to the outcome of Solitaire stent thrombectomy, especially the expression level on the postoperative 7-day has better application value. It can be used to predict the outcome of surgery.
