Abstract:
Objective To investigate the relationship between serum levels of thrombospondin-1(TSP-1)and thioredoxin 1(Trx1)and cognitive impairment after cerebral infarction.Methods A total of 155 patients with cerebral infarction(study group)admitted to a hospital from June 2021 to December 2022 were selected as the study objects,and were divided into normal cognitive function group(97 cases)and cognitive impair-ment group(58 cases)according to the scores of the montreal cognitive assessment scale(MoCA)after the pa-tients'condition stabilized.Another 150 healthy subjects in the same period were selected as the control group.Serum TSP-1 and Trx1 levels were detected by enzyme-linked immunosorbent assay(ELISA).Spearman analysis was used to analyze the correlation between serum TSP-1 and Trx1 levels and national in-stitutes of health stroke scale(NIHSS)score and MoCA score in patients with cerebral infarction.The predic-tive value of serum TSP-1 and Trx1 levels in cognitive impairment after cerebral infarction was analyzed by receiver operating characteristic(ROC)curve.Results Compared with the control group,the levels of serum TSP-1 and Trx1 in the study group were significantly higher,and the differences were statistically significant(P＜0.05).Compared with the normal cognitive function group,the levels of serum TSP-1 and Trx1 in the cognitive impairment group were significantly higher,and the difference was statistically significant(P＜0.05).Compared with the normal cognitive function group,the NIHSS score of the cognitive impairment group was significantly higher,and the MoCA score was significantly lower,with statistical significance(P＜0.05).Spearman correlation analysis showed that serum TSP-1 and Trx1 levels were positively correlated with NIHSS score(P＜0.05),and negatively correlated with MoCA score(P＜0.05)in patients with cerebral infarction.ROC curve analysis showed that the area under the curve(AUC)of serum TSP-1 to predict cogni-tive impairment after cerebral infarction was 0.834,and the sensitivity and specificity were 72.41％and 86.60％,respectively.Serum Trx1 level alone predicted the AUC of cognitive impairment after cerebral infarc-tion was 0.851,and its sensitivity and specificity were 70.69％and 85.57％,respectively.The AUC of the combined prediction of cognitive impairment after cerebral infarction was 0.926,which was significantly greater than that of serum TSP-1 alone(Z=3.050,P=0.002)and Trx1 alone(Z=2.846,P=0.004).Conclusion Serum TSP-1 and Trx1 levels are elevated in patients with cerebral infarction,and their levels have certain predictive value for cognitive impairment after cerebral infarction.
