ABSTRACT
Objective:To investigate the current status of social support and mental health among residents in Weifang and analyze the impact of social support on mental health,thus to provide reference for improving the mental health status of residents.Methods:A sample of 6174 residents in Weifang was investigated using Social Support Rate Scale (SSRS) and Kessler Psychological Distress Scale (K10).The data was analyzed statistically with Chi-square test,Kruskal-Wallis test and Multiple Logistic regression analysis.Results:About 0.3％ residents in Weifang reported low social support and 93 ％ residents showed good mental health.Gender,age,social support level and 3 dimensions of social support were associated with mental health respectively in the correlation analysis.In the multiple analyses,social support,subjective support,availability of support and mental health were positively correlated in the model of Good mental health and General mental health.Conclusion:The mental health status of residents in Weifang is not optimistic.The social support level has beneficial effect on mental health starus.Subjective support,objective support and the utilization of these supports imposes different degrees of inflnence on mental health status.
ABSTRACT
<p><b>OBJECTIVE</b>The purpose of this study was to develop RT- PCR assay for Rapidly detect and distinguish between Norovirus genogroup I and genogroup II with a pair of primers.</p><p><b>METHODS</b>A pairs of primers specific to capsid prote in ORF2 gene of G I and G II Norovirus were dsigned according to the published complete genome sequence, with which the RNA of Norovirus was extracted and RT-PCR amplification. The sensitivity, specificity of the RT- PCR assay was estimated and apply it to the detection of Norovirus in clinical specimens.</p><p><b>RESULTS</b>The results showed that the assay possessed high specificity for Norovirus detection and without any evident cross-reaction with other viruses, including rotavirus, enteric adenovirus and hepatitis A virus. The detection limit of RT-PCR assay for Norovirus G I and G II were up to 100 pg/ml and 10 pg/ml respectively.</p><p><b>CONCLUSION</b>The RT- PCR assay provide rapid and sensitive detection of Norovirus G I and G II and should prove to be useful for Norovirus diagnosis in the outbreaks of acute gastroenteritis.</p>
