Abstract:
Objective To investigate the expression levels of plasma circular RNA PTP4A2(circPTP4A2)and circTLK2 in elderly patients with acute ischemic stroke(AIS)and their predic-tive value for neurological functional outcomes.Methods A total of 122 elderly AIS patients admitted to our department from May 2021 to December 2022 were prospectively recruited,and according to their modified Rankin Scale(mRS)score at 3 months after stroke onset,they were divided into a good outcome group(mRS score≤2,81 cases)and a poor outcome group(mRS score:3-6,41 cases).Their baseline data,and plasma circPTP4A2 and circTLK2 levels were compared between the two groups.Multivariate logistic regression analysis was employed to iden-tify prognostic factors for poor outcomes in the elderly AIS patients.ROC curve analysis was ap-plied to evaluate the prognostic value of circPTP4A2 and circTLK2 for adverse outcomes in the patients.Pearson correlation analysis was performed to assess the relationship of plasma levels of circPTP4A2 and circTLK2 with NIHSS score,as well as mRS score.Results The plasma expres-sion levels of circPTP4A2 and circTLK2 were significantly higher in the poor outcome group than the good outcome group[2.08(0.87,2.77)vs 0.93(0.63,1.20),1.71(0.92,2.80)vs 0.75(0.49,1.09),P＜0.01].Multifactor logistic regression analysis showed that plasma circPTP4A2 and circTLK2 were independent predictive factors for poor functional outcomes in elderly AIS patients(P＜0.01,P＜0.05).ROC curve analysis demonstrated that the AUC value of combined circPTP4A2 and circTLK2 in predicting poor outcome in elderly AIS patients was 0.787(95％CI:0.691-0.883).Pearson correlation analysis revealed that the expression levels of circPTP4A2 and cir-cTLK2 in elderly AIS patients were mildly positively correlated with baseline NIHSS scores(r=0.463,r=0.456;P＜0.01)and moderately positively correlated with mRS scores at 3 months after stroke onset(r=0.682,r=0.604;P＜0.01).Conclusion Plasma circPTP4A2 and circTLK2 may be potential biomarkers for predicting neurological functional outcomes in elderly AIS patients.
