IN THIS ISSUE

Our staff is now in preparation for the upcoming launch date with the BMJ Publishing Group. The first important step is to accept and review all the articles in English using the ScholarOne system. Use of this system will be implemented starting from June. We believe that the new use of the ScholarOne system will help improve our manuscript reviewing process and increase the quality of published articles. Schizophrenia is a kind of chronic brain disease with unclear etiology, unsatisfactory effect of treatments, and poor functional outcomes. The present issue is focused on introducing research reports related to schizophrenia. It starts with Liu and colleagues introducing the biological research progress of schizophrenia in China with a special focus on neuroimaging research (resting state functional magnetic resonance imaging (fMRI) and functional connectivity, diffusion tensor imaging, and genetic imaging research), genetic research, and immunological research in 2017. They pointed out that applying neuroimaging technology to study schizophrenia is the most active research field in China in the past year. They also give a brief introduction of research progress of ultra-high-risk state populations. In the conclusion, the author commented on possible directions for future research.
