BACKGROUND Clinical studies demonstrate that the N-methyl-D-aspartate (NMDA) receptor antagonist, ketamine, induces rapid antidepressant effects in patients with refractive major depressive disorder and bipolar depression. This rapid onset of action makes ketamine a highly attractive drug for patients, particularly those who do not typically respond to(More)
Recent developments in depression studies have heightened the need for investigating adolescent major depressive disorder (MDD). Many previous neuroimaging studies used task designs and found consistent results in the dysfunction of brain regions in depressed adolescent patients. In this study, we aimed to evaluate the topological properties of brain(More)
Intramuscular (IM) antipsychotics are preferred for efficient control of agitation symptoms. Previous studies have demonstrated that IM ziprasidone is efficacious and safe for treatment of agitation in schizophrenia. However, clinicians now recognize that racial differences may contribute to altered therapeutic response and tolerability. This study compared(More)
Chinese herbal medicines possess the therapeutic potential for mood disorders. This double-blind, randomized, placebo-controlled study was designed to evaluate the efficacy and side effects of the herbal medicine called Free and Easy Wanderer Plus (FEWP) as an adjunct to carbamazepine (CBZ) in patients with bipolar disorders. One hundred and twenty-four(More)
BACKGROUND Accumulating epidemiological evidence shows that life event stressors are major vulnerability factors for psychiatric diseases such as major depression. It is also well known that social isolation in male mice results in aggressive behavior. However, it is not known how social isolation-induced aggression affects anxiety and depressive-like(More)
CONTEXT On May 12(th) 2008, a devastating earthquake measuring 8.0 on the Richter scale, struck Wenchuan county and surrounding areas in China. The prevalence of mental illness among children and adolescents in a rural town far from the earthquake epicenter is unknown. OBJECTIVE To assess the prevalence of posttraumatic stress disorder (PTSD) and(More)
Recently, evidence of linkage of schizophrenia to chromosome 13q22-q34 has been demonstrated in multiple studies. Based on structure and function, EFNB2 may be considered as a compelling candidate gene for schizophrenia on chromosome 13q33. We genotyped three single-nucleotide polymorphisms (SNPs: rs9520087, rs11069646, and rs8000078) in this region in 846(More)
BACKGROUND Individuals with early-onset depression may be a clinically distinct group with particular symptom patterns, illness course, comorbidity and family history. This question has not been previously investigated in a Han Chinese population. METHODS We examined the clinical features of 1970 Han Chinese women with DSM-IV major depressive disorder(More)
Recently, the DAOA gene locus on chromosome 13q32-q34 has been implicated in the etiology of schizophrenia. We genotyped three single-nucleotide polymorphisms (SNPs: rs778294, rs779293 and rs3918342) in this region in 126 Chinese family trios. In this study, we have identified statistically significant transmission disequilibrium in two markers rs778293(More)
Major depressive disorder (MDD) is a common, recurrent mental illness that affects millions of people worldwide. Accumulating evidence suggests that the N-methyl-D-aspartate (NMDA) receptor, a subtype of glutamate receptors, plays an important role in the neurobiology and treatment of this disease. Currently, the non-competitive NMDA receptor antagonist(More)
