Excessive free radical production or oxidative stress may be involved in the pathophysiology of schizophrenia as evidenced by increased superoxide dismutase (SOD) activities, a critical enzyme in the detoxification of superoxide radicals. This study compared plasma SOD activities in 78 never-medicated first-episode and 100 medicated chronic schizophrenia(More)
BACKGROUND Schizophrenia is associated with various abnormalities in the immune system including elevated levels of Interleukin-18 (IL-18), a potent inflammatory cytokine in T-helper 1 (Th1) responses. The aim of this study was to assess the clinical significance of serum IL-18 levels in various stages of schizophrenia. METHODS We measured serum IL-18(More)
Alterations in the inflammatory and immune systems have been documented to occur from the earliest stages of schizophrenia, and have been associated with neurodevelopmental changes. Cognitive impairment is a core feature in the pathology of schizophrenia, and recent studies showed a significant increase in serum IL-18 in schizophrenia, and a putative role(More)
Oxidative stress-induced damage to neurons may contribute to cognitive deficits during aging and in neurodegenerative disorders. Schizophrenia has a range of cognitive deficits that may evolve from oxidative stress, and this study examines this association of oxidative stress with cognitive deficits in schizophrenia. We recruited 296 chronic schizophrenia(More)
Azinomycin B is a hybrid polyketide/nonribosomal peptide natural product and possesses antitumor activity by interacting covalently with duplex DNA and inducing interstrand crosslinks. In the biosynthetic study of azinomycin B, a gene (orf1) adjacent to the azinomycin B gene cluster was found to be essential for the survival of the producer, Streptomyces(More)
BACKGROUND Over the past two decades, China has experienced a dramatic increase in methamphetamine (MA) abuse. This study examined gender-specific socio-demographic and clinical characteristics of MA use among Han Chinese, which has previously received little systematic study. METHODS This analysis described MA-related socio-demographic and clinical(More)
This study aimed to examine the prevalence and clinical associated variables of tardive dyskinesia (TD) in a large sample of Chinese inpatients with schizophrenia on long-term treatment with clozapine versus typical antipsychotics. A total of 584 male inpatients with schizophrenia on long-term clozapine (n=341) or typical antipsychotic (n=243) treatment(More)
