Correlation between Serum Levels of ANGPTL4 and sTLT-1 and Cognitive Function and Prognosis in Elderly Patients with Vascular Dementia
Objective To investigate the correlation between serum Angiopoietin-like protein 4(ANGPTL4)and soluble bone marrow cell-like transcription factor-1(sTLT-1)levels and cognitive function and prognosis in elderly patients with vascular dementia(VD).Methods A total of 92 elderly patients with vascular dementia admitted to Hebei Yanda Hospital from June 2020 to June 2022 were selected as the study group.They were divided into mild(n=30),moderate(n=36)and severe groups(n=26)according to the minimum mental state examination(MMSE)score,and 92 patients with healthy physical examination during the same period were selected as the control group.According to the prognosis of patients,the cognitive dysfunction was divided into grade Ⅰ～Ⅱ and grade Ⅲ.ELISA method was used to detect the levels of serum ANGPTL4 and sTLT-1.Pearson and Spearman methods were used to analyze the correlation between serum ANGPTL4 and sTLT-1 and MOCA scores.Logistic regression analysis was used to analyze the influencing factors of the prognostic grade Ⅲ of elderly patients with vascular dementia.The receiver operating characteristic(ROC)curve was plotted to analyze the predictive value of serum ANGPTL4 and sTLT-1 levels in the prognostic grade Ⅲ in elderly patients with vascular dementia.Results The serum ANGPTL4 level(987.57±53.25 pg/ml)in the study group was lower than that in the control group(1 108.35±62.13 pg/ml),and the serum sTLT-1(68.01±5.15 pg/ml)level was higher than that in the control group(50.12±4.57 pg/ml),with significant differences(t=14.158,24.922,all P＜0.05).Serum ANGPTL4 levels and MOCA scores were decreased sequentially in the mild,moderate and severe groups(F=33.495,66.617),while serum sTLT-1 level was increased sequentially(F=66.718),and the differences were statistically significant(all P＜0.05),respective.Pearson analysis showed that serum ANGPTL4 was negatively correlated with sTLT-1(r=-0.621,P＜0.05).Spearman analysis showed serum levels of ANGPTL4 and sTLT-1 were positively and negatively correlated with MoCA scores,respectively(r=0.545,-0.557,all P＜0.05).The serum ANGPTL4 level(953.45±51.16 pg/ml)in the prognostic patients of grade Ⅲ was lower than that of grade Ⅰ～Ⅱ(1 005.76±54.27 pg/ml),and the serum level of sTLT-1(73.14±5.40 pg/ml)was higher than that of grade Ⅰ～Ⅱ(65.28±5.02 pg/ml),with significant differences(t=4.490,6.967,all P＜0.05).Logistic regression analysis showed low expression of ANGPTL4[OR(95％CI):5.089(1.833～14.129)]and high expression of sTLT-1[OR(95％CI):4.258(1.739～10.428)]were risk factors affecting the prognosis of elderly patients with vascular dementia(P＜0.05).According to the ROC curve,the combined prediction of two for the grade Ⅲ prognosis of elderly vascular dementia patients was better than the individual prediction of ANGPTL4 and sTLT-1(Z=2.135,3.268,all P＜0.05).Conclusion Serum ANGPTL4 level was decreased but sTLT-1 level was increased in elderly patients with vascular dementia,and ANGPTL4 and sTLT-1 were closely related to cognitive function and prognosis.
