Abstract:
Objective To analyze the value of abnormal expression of platelet membrane P-selectin(CD62p)and zonula occluden-1 in predicting the instability of carotid atherosclerotic plaques in elderly patients with cerebral infarction.Methods A total of 203 elderly patients with cerebral in-farction admitted to our department from March 2021 to July 2023 were enrolled,and based on their status of carotid plaques,they were divided into a unstable plaque group(45 cases),a stable plaque group(89 cases),a no-plaque group(69 cases).General information was collected,and the serum levels of CD62p and zonula occluden-1 were measured.The risk factors for carotid athero-sclerotic plaque instability and their predictive value were analyzed.Results Statistical differences were observed in the levels of low-density lipoprotein,homocysteine(Hcy),C-reactive protein,IL-6,fibrinogen,and intercellular adhesion molecule-1(ICAM-1)among the three groups(P＜0.05,P＜0.01),so were in the serum levels of CD62p and zonula occluden-1(P＜0.05).In the un-stable plaque group,the serum levels of CD62p and zonula occluden-1 were positively correlated with the levels of low-density lipoprotein,Hcy,C-reactive protein,IL-6,fibrinogen,and ICAM-1(P＜0.05,P＜0.01).In the stable plaque group,the serum levels of CD62p and zonula occluden-1 were positively correlated with the levels of low-density lipoprotein,Hcy,C-reactive protein,IL-6 and ICAM-1(P＜0.05,P＜0.01).Logistic regress analysis showed that the serum levels of low-density lipoprotein,Hey,C-reactive protein,IL-6,fibrinogen,ICAM-1,CD62p and zonula occlu-den-1 were risk factors for plaque instability(P＜0.01).ROC curve analysis indicated that the AUC value of CD62p and zonula occluden-1 in predicting plaque instability was 0.850 and 0.838,respectively(P＜0.01).Conclusion Abnormal expression of serum CD62p and zonula occluden-1 can effectively predict the instability of carotid atherosclerotic plaques in elderly patients with cer-ebral infarction.
