Abstract:
Objective To investigate the correlation between serum levels of prostaglandin-endoperoxide synthase 2(PTGS2),chitinase-3-like protein 1(CHI3L1)and cognitive impairment caused by cerebrovascular disease.Methods From October 2020 to October 2022,96 inpatients with cerebrovascular diseases admitted to the Third People's Hospital of Chengdu were regarded as the study subjects.The basic clinical data of the patients were recorded,the serum levels of PTGS2 and CHI3L1 were detected by enzyme-linked immunosorbent assay,and these patients were grouped into normal group(n=60)and impaired group(n=36)based on the presence or absence of cognitive impairment.The correlation between serum PTGS2 and CHI3L1 levels and fasting blood glucose(FBG)and homocysteine(Hcy)was analyzed by Pearson method.Logistic regression model was used to determine whether serum PTGS2 and CHI3L1 were independent risk factors for predicting cognitive impairment.Receiver operating characteristic(ROC)curve was drawn,and the predictive value of CHI3L1 and serum PTGS2 expression level in cognitive impairment in patients with cerebrovascular disease was analyzed according to the area under the curve(AUC).Results Compared with the normal group,the levels of serum PTGS2(29.30±9.46 pg/ml vs 17.86±5.40 pg/ml)and CHI3L1(13.04±4.06 pg/ml vs 7.51±2.66 pg/ml)in the disorder group were increased,and the differences were statistically significant(t=7.553,8.065,all P＜0.05).Multivariate Logistic regression analysis showed that FBG(OR=3.612,95%CI:2.324～5.614),Hcy(OR=2.584,95%CI:1.351～4.944),PTGS2(OR=1.964,95%CI:1.194～3.231)and CHI3L1(OR= 1.556,95%CI:1.023～2.367)were independent risk factors of cognitive impairment(all P＜0.05).PTGS2 was positively correlated with FBG and Hcy(r=0.368,0.551,all P＜0.05),and CHI3L1 was positively correlated with FBG and Hcy(r=0.510,0.376,all P＜0.05).The ROC curve showed that the area under curve(AUC)of PTGS2 and CHI3L1 in predicting cognitive impairment was 0.819 and 0.829,respectively.The AUC of the combined prediction of cognitive impairment was 0.902,which was obviously higher than that of the independent prediction of the two(Z =2.089,2.293;P=0.037,0.021),with sensitivity and specificity of 77.78%and 98.33%,respectively.Conclusion PTGS2 and CHI3L1 were highly expressed in the serum of patients with cognitive impairment of cerebrovascular disease,indicating that both were related to cognitive impairment of patients with cerebrovascular disease.
