<qa>  What is the name of the neurobiological basis of schizophrenia?Schizophrenia is one of the most serious mental disorder,which is characterized by high prevalence rate ,high recurrence rate, could increase patients disability and burden of disease. But the pathological mechanism is so far unknown. Until recently, more attention are focused on gene dysregulation hypothesis. The preliminary works of our laboratory prompted that microRNA-30e gene polymorphism and expression abnormal may be related to schizophrenia. Combined with previous studies showed that miRNA disorder involved in neurodevelopmental obstacle and neuropsychiatric disease, the investigators surmised: miR-30e dysregulation can impact the occurrence and development of schizophrenia. This study will carry on the multidimensional research by using the technology of neurobiology, molecular genetics,neuroimaging and so on, and integrate methods of molecular, cell, animal and human body tracking, so as to:1 Explaining the transcription and regulation mechanisms of target genes of miR-30e,and building the gene regulatory network of schizophrenia as the core of miR-30e.2To investigate the pathogenesis of miR-30e participate in schizophrenia, and to evaluate the clinical value of miR-30e in peripheral blood on the disease diagnose, genotyping, predicting efficacy and ending. The object of this study is to provide new scientific data and research ideas for further exploring the neurobiological basis of schizophrenia, and recognize pathophysiological mechanisms of schizophrenia, ultimately to improve and strengthen the new situation in schizophrenia prevention.
