ABSTRACT
Objective To study the impacts of quality of life,stress response and sources of stress on mental health of community residents.Methods A total of 703 questionnaires completed by community residents living in Hangzhou and Cangzhou were prospectively collected.All the subjects were assigned o five age groups:18-25 years old group,26-35 years old group,36-50 years old group,51-64 years old group and ≥65 years old group.Psychological health status was compared between the groups by using analysis of variance.Results Significant difference in mental health was found among 5 age groups.Correlation analysis showed that quality of life,stress response and sources of stress had significant effects on mental health.Conclusion Our data suggest significant impacts of quality of life and stress on mental health of community residents.
ABSTRACT
Disasters are traumatic events that are always incongruent with our existing cognitive structures. Immediate negative psychological impact and traumatic related psychiatric disorders are popular among survivals involving the disasters. Super-half of survivals involving the "5" 12" Wenchuan earthquake experienced the symptoms of anxiety or increased arousal. 12.59% of survivals were met with the ASD diagnosis. 21.29% of adults and 10.21% of adolescents were met with the PTSD diagnosis 5 months after the major earthquake. Immediately negative psychological impact and high prevalence of traumatic related psychiatric disorders among survivals were confirmed.More effort should be paid on the disaster related patients in emergency department with psychiatric issues. Also, the long-term psychological service is necessary for Sichuan Pest-Disaster Reconstruction Projects.
ABSTRACT
Background 5-hydroxytryptamine 2A receptor (5-HT2A) gene has been regarded as a candidate gene for susceptibility to schizophrenia. In particular, the 5-HT2A receptor has received much attention because it demonstrates to be an important site of action of atypical antipsychotic agents to alleviate negative symptoms. The current study investigated whether the 5-hydroxytryptamine 2A receptor (5-HT2A) gene T102C polymorphism was associated with treatment response to risperidone in the first episode Chinese patients with schizophrenia.Methods 201 first episode Chinese Han patients with schizophrenia were given risperidone for up to 56 days.Genotyping of 5-HT2A gene T102C polymorphism were performed by using PCR-RFLP. The Positive and Negative Symptom Scale (PANSS) was used for the evaluation of the severity of psychotic symptoms before and after 8 weeks treatment with risperidone.Results 5-HT2A receptor 102 -T/T genotype was significantly associated with both the PANSS total and negative syndrome subscale scores before treatment, and with the reduction rates in both the PANSS total and negative syndrome subscale scores after eight weeks risperidone treatment.Conclusions The results suggest that 5-HT2A T102C A/A1 genotype subgroup influences individual response to risperidone in first-episode Chinese patients with schizophrenia.
