Abstract:
Objective To investigate the diagnostic value of microRNA (miRNA) in peripheral venous blood for depressive disorder.Methods Real-time fluorescence quantitative PCR (RT-qPCR) was used to verify expression level of miRNAs in peripheral blood of non-specific mental retardation children,which were aberrantly expressed in depressive disorder patients,and then Receiver Operating Characteristics (ROC)curve was employed to confirm the sensitivity and specificity of abnormal miRNA expression in depressive disorder and non-specific mental retardation.Results MiR-1972,miR-26b,miR-4485,miR-4498 and miR-4743 were upregulated significantly in case group of depressive disorder(P＜0.05),meanwhile miR-4485 and miR-4743 in aforementioned 5 miRNAs also upregulated significandy in patients of non-specific mental retardation(P＜0.05),but miR-26b showed no significant difference between case group of non-specific mental retardation and the control group (P＞0.05).The ROC curve of miR-26b in depressive disorder patients and their control group showed that the sensitivity and specificity were 0.609,0.664 respectively,and the area square under the curve was 0.614(P=0.021).The ROC curve of miR-26b in patients of depressive disorder and non-specific mental retardation indicated that the sensitivity and specificity were 0.784 and 0.471,and area square under the curve was 0.643 (P=0.003).Conclusion miR-26b probably have diagnostic value for depressive disorder,which may comorbidity with non-specific mental retardation.But genetic and psychosocial mechanism of comorbidity still needs further exploration.
