Abstract:
Objective To explore the relationship between the serum levels of absent in melanoma 2(AIM2)and apolipoprotein J(Apo J)and the severity and prognosis of vascular dementia(VD).Methods From October 2020 to September 2022,128 patients with vascular dementia were collected as the study group in the Second People's Hospital of Binzhou.Based on the mini-mental state examination(MMSE)score,the severity of the condition was evaluated and the study group was separated into mild group(n=43),moderate group(n=54)and severe group(n=31).After 90 days of treatment,the prognosis of patients was evaluated based on the ability of daily living(ADL)scale score and grouped into grade Ⅰ group(n=66),grade Ⅱ group(n=40)and grade Ⅲgroup(n=22).Another 96 healthy individuals who underwent physical examination were selected as the control group.The expression levels of serum AIM2 and Apo J were detected by qRT-PCR and ELISA methods,and the differences between the groups were compared.Spearman method was applied to analyze the correlation between serum AIM2 and ApoJ expression levels and MMSE scores,and the relationship between serum AIM2 and Apo J expression levels and prognosis in patients with vascular dementia.Logistic regression was applied to analyze the prognostic factors of vascular dementia patients.Results The expression level of serum AIM2 mRNA(3.11±0.57 vs 1.06±0.23)in the study group was higher than those in the control group,while the expression level of serum ApoJ(68.83±12.24 ng/L vs 81.07±13.15 ng/L)was lower than that in the control group,with significant differences(t=32.054,7.174,all P＜0.001).The expression level of serum AIM2 mRNA in the severe group was higher than that in the mild and moderate groups(q=12.807,15.780),the expression level of serum Apo J and MMSE score in the severe group were lower than those in the mild and moderate groups(q=26.201,4.301;12.193,20.802),the expression level of serum AIM2 mRNA in the moderate group was higher than that in the mild group(q=14.688),and the expression level of serum Apo J and MMSE score in the moderate group were lower than those in the mild group(q=20.338,37.537),with significant differences(all P＜0.001).The expression level of serum AIM2 mRNA(5.27±0.60)in the grade Ⅲgroup of vascular dementia was higher than that in the grade Ⅱ(3.36±0.58)and grade Ⅰ groups(2.23±0.55),while the expression level of serum Apo J(51.22±12.21 ng/L)was lower than that in the grade Ⅱ(64.15±12.23 ng/L)and grade Ⅰgroups(77.53±12.25 ng/L).The expression level of serum AIM2 mRNA in the grade Ⅱ group was higher than that in the gradeⅠ group,while the expression level of serum Apo J in the grade Ⅱ group was lower than that in the grade Ⅰ group,with significant differences(q=5.630～30.740,all P＜0.001).The level of serum AIM2 in patients with vascular dementia was negatively correlated with MMSE score but positively correlated with prognosis(ADL grade)(r=-0.535,0.432,all P＜0.001),while the level of serum Apo J in patients with vascular dementia was positively correlated with MMSE score but negatively correlated with prognosis(ADL grade)(r=0.467,-0.496,all P＜0.001).Serum AIM2 mRNA[OR(95％CI):2.746(1.481～5.091)],Apo J[OR(95％CI):0.496(0.311～0.791)],and MMSE score[OR(95％CI):0.568(0.347～0.931)]were influencing factors for the prognosis of vascular dementia patients(all P＜0.05).Conclusion The increase of serum AIM2 mRNA expression level and the decrease of serum Apo J expression level in patients with vascular dementia were closely related to the clinical severity and prognosis of patients,which may effectively evaluate the prognosis of patients.
