Abstract:
Objective To analyze the expression levels of serum microRNA(miR)-211 and miR-202 in patients with Alzheimer's disease and their correlation with cognitive function,anxiety and depression.Methods A total of 90 patients with Alzheimer's disease admitted to Hebei Yanda Hospital from March 2019 to March 2022 were selected as the research group.According to the Clinical Dementia Rating(CDR)score,the patients were grouped into mild group(n=24),moderate group(n=48)and severe group(n=18).Another 90 healthy individuals who underwent physical examination were collected as the control group.The expression levels of miR-211 and miR-202 in serum were compared.Pearson method and Spearman method were used to analyze serum miR-211 and miR-202 and their correlation with cognitive function,anxiety and depression.Logistic regression analysis was used to analyze the influencing factors of Alzheimer's disease.Results The expression levels of serum miR-211(0.59±0.16,1.01±0.31)and miR-202(0.35±0.10,1.00±0.32)were significantly reduced in the research group and control group,with significant differences(t=11.422,18.393,all P<0.05).Serum miR-211(0.73±0.21,0.62±0.17,0.32±0.08)expression levels,miR-202(0.51±0.15,0.33±0.10,0.19±0.04)expression levels,mini-mental state examination(MMSE)score(22.54±1.41 score,19.35±1.01 score,16.23±1.00 score)and Montreal cognitive assessment(MoCA)score(25.35±2.60 score,18.59±1.32 score,16.59±1.24 score)in the mild,moderate and severe groups gradually decreased,and the differences were statistically significant(F=32.006,46.917,163.048,163.703,all P<0.05).Compared with mild group,the serum miR-211,miR-202,MMSE and MoCA scores of severe group and moderate group were reduced,and the differences were statistically significant(t=3.685～25.375,all P<0.05).The mild,moderate and severe groups had a gradual increase in Hamilton anxiety scale(HAMA)score(12.34±1.27 score,20.59±2.09 score and 31.29±2.19 score)and Hamilton depression scale(HAMD)score(14.35±2.13 score,23.89±2.20 score and 35.35±1.21 score),and the differences were statistically significant(F=496.059,553.939,all P<0.05).According to Pearson correlation analysis,miR-211 was positively correlated with miR-202(r=0.651,P<0.05).According to Spearman correlation analysis,miR-211 and miR-202 were positively correlated with MMSE and MoCA(r=0.539～0.585,all P<0.05)and negatively correlated with HAMA and HAMD(r=-0.651～-0.539,all P<0.05).Logistic regression analysis showed that the low expression of miR-211[OR(95%CI):5.321(1.648～17.180)]and miR-202[OR(95%CI):3.158(1.989～5.012)]were risk factors for Alzheimer's disease(P<0.05).Conclusion The serum expression levels of miR-211 and miR-202 in patients with Alzheimer's disease were reduced,indicating miR-211 and miR-202 were closely related to cognitive function,anxiety and depression.
