The mediating role of mental capital in understanding social support and job satisfaction / 中华劳动卫生职业病杂志

Objective@#To understand the relationship between perceived social support, psychological capital and job satisfaction, and analyze the mediating effect of psychological capital between perceived social support and job satisfaction.@*Methods@#In 2017, June to July, we use cluster random sampling method to evaluate 888 medical staff from 5 hospitals in Jinan and Yantai in Shandong provience by Perceived Social Support Scale、PsyCap Questionnaire and MinnesotaSatisfaction Questionnaire.@*Results@#Correlation analysis showed that perceived social support was significantly positively correlated with self-efficacy, hope, resilience, optimism and job satisfaction (r=0.42, 0.42, 0.56, 0.47, P<0.05) . There was a significant positive correlation between job satisfaction and self-efficacy, hope, resilience and optimism (r=0.45, 0.50, 0.43, 0.46, P< 0.05) . The structural equation model shows that hope and optimism play a significant partly mediating effect between perceived social support and job satisfaction.@*Conclusion@#Perceived social support is a positively predictive factor of job satisfaction in medical staff. The Increase of perceived social support and psychological capital are conducive to improving job satisfaction of medical staff's.

Identification and Molecular Analysis of H5N2 Subtype Highly Pathogenic Avian Influenza Virus Isolated From Goose / 生物化学与生物物理进展

A H5N2 subtype avian influenza virus isolated from goose belongs to highly pathogenic avian influenza virus, and the intravenous pathogenicity indexes (IVPI) =2.99. But ducks are not sensitive to this isolated influenza virus. The virus can infect mouse but only replicates in lung and has no pathogenicity. HA and NA gene of this isolated strain share 99.4% and 99.8% nucleotide sequence identity to the HA gene of A/chicken/Hubei/ 489/2004 (H5N1) and the NA gene of A/chicken/Jilin/53/01 (H9N2), and share 99.3% and 99.6% amino acid sequence identity to the HA protein of A/chicken/Hubei/489/2004 (H5N1), A/swan/Guangxi/307/2004 (H5N1), A/wild duck/ Guangdong/314/2004(H5N1), A/chicken/Henan/210/2004(H5N1) and the NA protein of A/chicken/ Jilin/53/01 (H9N2). There are several continuous basic amino acids (-RRRKKR-) at the cleavage site of HA protein. Phylogenetic trees analysis of HA and NA gene suggests that the isolated influenza virus probably originated from the reassortment of H5N1 and H9N2 subtype influenza virus.
