Abstract:
Objective To analyze the application value of cervical vascular color Doppler ultrasound com-bined with serum microRNA-222-3p(miR-222-3p)and microRNA-206(miR-206)in the diagnosis of carotid artery stenosis in patients with cerebral infarction.Methods A total of 90 patients with cerebral infarction ad-mitted to this hospital from July 2018 to July 2022 were selected as the study group,and were divided into mild stenosis group(29 cases),moderate stenosis group(35 cases),and severe stenosis group(26 cases)ac-cording to the degree of carotid artery stenosis.In addition,96 healthy people who underwent physical exami-nation in the hospital were selected as the control group.Real-time fluorescence quantitative PCR was used to detect the levels of serum miR-222-3p and miR-206 in each group.All patients with cerebral infarction under-went cervical vascular color Doppler ultrasound examination,and the clinical data of patients with different de-grees of stenosis were analyzed.Multivariate Logistic regression was used to analyze the factors affecting the degree of carotid artery stenosis in patients with cerebral infarction.The receiver operating characteristic(ROC)curve was used to evaluate the diagnostic value of carotid ultrasound indicators,serum miR-222-3p and miR-206 levels for the degree of carotid artery stenosis in patients with cerebral infarction.Results Compared with the control group,the study group had a significant increase in the serum level of miR-222-3p and a sig-nificant reduction in the serum level of miR-206(P＜0.05).Compared with the mild stenosis group,the peak systolic velocity(PSV),end diastolic volume(EDV)and serum miR-222-3p level were increased,and the ser-um miR-206 level was decreased in the moderate stenosis group and the severe stenosis group(P＜0.05).Compared with moderate stenosis group,EVD,PSV and serum miR-222-3p levels were significantly in-creased,and miR-206 level was decreased in severe stenosis group(P＜0.05).EVD,PSV,serum miR-222-3p level were risk factors for carotid artery stenosis in patients with cerebral infarction,and serum miR-206 level was a protective factor for carotid artery stenosis in patients with cerebral infarction(P＜0.05).The area un-der the curve of EVD,PSV combined with serum miR-222-3p and miR-206 in diagnosing the degree of carotid artery stenosis in patients with cerebral infarction was 0.991,and the sensitivity and specificity were 98.36％and 93.10％,respectively.It was better than that of EVD,PSV,serum miR-222-3p,and miR-206 alone(Zcombination-EVD=2.927,P=0.003,Z combination-PSV=2.834,P=0.005,Zcombination-miR-222-3p=3.300,P=0.001,Zcombination-miR-206=3.730,P＜0.001).Conclusion Cervical vascular color Doppler ultrasound combined with ser-um miR-222-3p and miR-206 has application value in the diagnosis of carotid artery stenosis in patients with cerebral infarction.
