Clinical observations indicate that atypical antipsychotics, especially clozapine, induce obsessive–compulsive (OC) symptoms in schizophrenia patients. Recent data from neuroimaging and clinical trials suggest a role for altered glutamate neurotransmission in the etiology of OC disorder (OCD), and SLC1A1, GRIN2B, and GRIK2 have all been reported to regulate(More)
The leucine-rich repeat kinase-2 (LRRK2) gene has been regarded as 1 of the most common genetic causes of Parkinson's disease (PD). We hypothesized that LRRK2-susceptible allele(s) for PD might pose a risk for Alzheimer's disease (AD). In this study, we screened 12 LRRK2 gene variants in 2 independent cohorts from southwestern China (341 AD patients and 435(More)
Cognitive impairment is one of the core symptoms in schizophrenia, which reflects the neurodevelopmental deficits in the etiology of this disease. Brain-derived neurotrophic factor (BDNF) plays an important role in various neurodevelopmental processes. Growing evidence has shown that BDNF may be involved in the etiology of schizophrenia. The aim of this(More)
With the recent attention to the importance of evidence-based medicine in psychiatry, a number of treatment guidelines have been published. This survey investigated prescribing pattern and predictors for guideline disconcordance in the acute treatment of bipolar depression across mainland China. Pharmacological treatments of 1078 patients with bipolar(More)
The α-subunit of C-phycocyanin (CpcA) was expressed in Escherichia coli and purified. The recombinant CpcA inhibited the growth of human colon carcinoma COLO 205 cells. Typical apoptotic morphological characteristics, such as chromatin condensation and nuclear fragmentation, were observed in CpcA-treated COLO 205 cells by fluorescence microscopy and(More)
Mitochondrial dysfunction has been widely reported in psychiatric and neurodegenerative diseases. We aimed to investigate the association between matrilineal structures of Han Chinese populations and Alzheimer's disease (AD) by a 2-stage case-control study: A total of 341 AD patients and 435 normal individuals from Southwest China were analyzed for(More)
BACKGROUND Early identification of patients with bipolar disorder during their first depressive episode is beneficial to the outcome of the disorder and treatment, but traditionally this has been a great challenge to clinicians. Recently, brain-derived neurotrophic factor (BDNF) has been suggested to be involved in the pathophysiology of bipolar disorder(More)
Neuropsychological endophenotype approach is an emerging strategy in schizophrenia research to understand and identify the functional importance of genetically transmitted, brain-based deficits present in this disorder. Accumulating evidence indicated that working memory deficit is a core neuropsychological dysfunction in schizophrenia and a primary(More)
Mitochondrial dysfunction was widely reported in schizophrenia patients in recent studies. Leucine-rich repeat kinase 2 (LRRK2) is a mitochondrial protein, and mutations in the LRRK2 gene can induce mitochondrial dysfunction. LRRK2 mutations have been reported to be the most frequent genetic cause of Parkinson's disease (PD). We were interested in whether(More)
In this study, we examined whether common variants in the G protein-coupled receptor kinase 6 gene (GRK6) confers susceptibility to schizophrenia in Chinese. We genotyped two common variants in 697 schizophrenia patients and 563 healthy control subjects. No significant difference in either allele or genotype comparisons between the case and control groups(More)
