This analysis reports the changes in disease severity, treatment patterns, quality of life and outcomes in a Chinese cohort according to the presence (PPS+) or absence (PPS-) of painful physical symptoms.

Case-control association study of Disrupted-in-Schizophrenia-1 (DISC1) gene and schizophrenia in the Chinese population.

Disrupted-in-Schizophrenia-1 (DISC1) has first been identified as a candidate gene for schizophrenia through study of a Scottish family with a balanced (1; 11) (q42.1; q14.3) translocation.

Association between the brain-derived neurotrophic factor (BDNF) gene and schizophrenia in the Chinese population.

Brain-derived neurotrophic factor (BDNF) belongs to a family of the neurotrophin which plays important roles in the development of the brain. BDNF has been suggested as a factor that increases the risk of schizophrenia. In this study, we genotyped three single nucleotide polymorphisms (SNPs) in the BDNF gene using a set sample of Han Chinese subjects consisting of 560 schizophrenes and 576 controls.
