Major Depressive Disorder is one of the most common mental diseases,which increases health-care costs and the financial burden to families and societies. Considering its complex clinical symptoms and diversity of comorbidity, depressive disorder's recognition，diagnosis，and antihistone are based on symptomatology,which is lack of multidimensional diagnosis technique based on clinical pathological characteristics,as well as lack of individualized therapy strategy based on quantified evaluation. Besides, other physical diseases，such as nervous system diseases, cardiovascular diseases，endocrine diseases, have the high comorbidity of depressive disorder. However，there is no precise diagnosis technique or standardized therapy strategy. With all those taken into consideration,our study is aimed to adopt E-mental health and m-Health to explore multi-dimensional diagnosis, individualized therapy and management technique based on molecular biology,nerve electrophysiology，and neuroimaging technology etc.
