Abstract:
Objective To analyze the correlation and predictive value of serum microRNA(miR)-34b and miR-181c levels with the prognosis of elderly acute ischemic stroke(AIS)patients with mechanical thrombec-tomy.Methods A total of 180 elderly AIS patients in Suining Central Hospital from January 2023 to January 2024 were selected as the study group.According to the 2∶1 control principle,90 healthy elderly patients at the same age and during the same period were selected as the control group.The general data and serum miR-34b and miR-181c levels in the two groups were compared,and the serum miR-34b and miR-181c levels of pa-tients with different degrees of neurological impairment in the study group were compared,and the correlation between the levels of serum miR-34b and miR-181c and the degree of neurological impairment in elderly AIS patients was analyzed.General data and serum miR-34b and miR-181c levels of patients with different progno-sis were compared at admission,and factors affecting adverse prognosis were analyzed,as well as the value of serum miR-34b and miR-181c in predicting adverse prognosis.Results The serum miR-34b level in the study group was lower than that in the control group,and the serum miR-181c level was higher than that in the con-trol group(P＜0.05).In the study group,the serum miR-34b level of patients with severe neurological im-pairment was lower than that of moderate and mild patients,the level of miR-181c was higher than that of moderate and mild patients,and the level of miR-181c was higher than that of mild patients(P＜0.05).The serum miR-34b levels in patients with severe neurological impairment in the study group were lower than those in moderate and mild patients at admission,and those in moderate patients were lower than those in mild patients,miR-181c levels were higher than those in moderate and mild patients,and moderate patients were higher than those in mild patients(P＜0.05).The level of serum miR-34b was negatively correlated with the degree of neurological impairment,and the level of miR-181c was positively correlated with the degree of neu-rological impairment(P＜0.05).The proportion of diabetes mellitus,National Institutes of Health Stroke Scale(NIHSS)score at admission,time from onset to treatment and serum miR-181c level in patients with poor prognosis were higher than those with good prognosis,and the level of miR-34b was lower than those with good prognosis(P＜0.05).Diabetes mellitus,time from onset to treatment,NIHSS score at admission,and serum miR-181c level were all independent risk factors for poor prognosis in elderly AIS patients with me-chanical thrombectomy,while serum miR-34b level was an independent protective factor(P＜0.05).The area under the curve(AUC)of serum miR-34b and miR-181c were 0.751 and 0.758 respectively in predicting the poor prognosis,and the AUC of combined miR-34B and miR-181c was 0.867,which was greater than the AUC predicted by alone(P＜0.05).Conclusion The levels of serum miR-34b and miR-181c are the factors affect-ing the poor prognosis of elderly AIS patients with mechanical thrombectomy,and have the predictive value for the prognosis.
