Study population: From 2014 to 2016, 28 patients with mental disorders were enrolled in the second affiliated Hospital of Zhejiang University, aged 21 -66 years, with an average age of 42.0 years.

Brief summary: Schizophrenia (Schizophrenia,Sc), biphasic affective disorder (Bipolar disorder,BPD), major depression (major depressive disorder,MDD), anxiety disorder (Anxiety disorder,An) and other mental disorders have obvious family aggregation, with heritability of 60 -90%. This kind of common mental illness seriously affects the psychosomatic health and quality of life of patients, and places a great mental and economic burden on the society and family. At present, the diagnosis of mental illness is mainly based on clinical symptoms. With the development of molecular biology, genomics has become a new way to study mental illness. MicroRNA (miRNA) is a class of eukaryotic endogenously non-coding single-stranded RNA, which can regulate gene expression by binding to specific mRNA or regulating the protein translation process of specific mRNA. MiRNA widely exists in plasma and serum, and the type and quantity of miRNA in plasma and serum change with different physiological and disease conditions. It is reported that the expression profile of miRNA in brain tissue of schizophrenia is significantly different from that of normal subjects. In addition, the study found that the specific miRNA detected in peripheral blood can directly reflect the condition of the disease, which may use miRNA in peripheral blood as a clinical biological marker. In order to detect the expression of various miRNA in plasma, high throughput miRNA chip detection has become the first choice for primary screening. In this study, the investigators intend to detect the difference of miRNA expression in peripheral blood of different types of schizophrenia by high throughput miRNA chip, and analyze the correlation between them. It is hoped to provide the basis for the diagnosis and occurrence and development of clinical psychotic patients.
