RESUMO
Objective:To investigate the status of work performance among rural doctors in Shanxi province and the factors related to their performance.Methods:From July to September 2019, 528 rural doctors in Shanxi province were selected by multi-stage stratified cluster sampling for the survey. Their job competency, job performance, psychological capital and burnout were evaluated. The structural equation model was used to construct the job performance analysis based on post competency.Results:The total score of post competency of rural doctors in Shanxi province was (188.6±20.3), and the total score of job performance was (71.3±11.5), both of which were in the middle level. The structural equation model was well fitted [goodness-of-fit index (GFI)=0.958, normal fix index (NFI)=0.920, adjusted goodness-of-fit index (AGFI)=0.910, root mean square error of approximation (RMSEA)=0.076]. Post competency, psychological capital and job burnout had direct effects on job performance ( P<0.05), with influence coefficients of 0.64, 0.35 and -0.25, respectively. Job competency indirectly affected job performance through psychological capital and job burnout ( P<0.05). Conclusion:The study suggest that higher post competency would facilitate to improve the work performance of rural doctors.
RESUMO
<p><b>OBJECTIVE</b>To investigate the effects of Modified Sanhuang Decoction (, MSD) enema on the serum tumor necrosis factor alpha (TNF-α) and colonic mucosa interleukin-1β (IL-1β), interleukin-6 (IL-6) levels in experimental ulcerative colitis (UC) rats.</p><p><b>METHODS</b>Forty-five male Wistar rats were randomly divided into 4 groups: normal group (n=12), model group (n=11), salazosulfapyridine (SASP) group (n=11) and MSD group (n=11). The UC model was induced by 2,4,6-trinitrobenzene sulfonic acid (TNBS)/ethanol solution. Rats in the normal group and model group were clystered with 0.9% normal saline, while in the SASP group and MSD group were clystered with SASP and MSD enema, respectively. After drug administration (10 mL/kg body weight, for 7 days), colonic gross changes and colonic mucosa histology were observed, serum TNF-α and colonic mucosa IL-1β, IL-6 levels were tested by enzyme linked immunosorbent assay and radioimmunoassay, respectively.</p><p><b>RESULTS</b>As compared with the normal group, the experimental UC rats, the colonic mucosal damage index scores (CMDIs), histopathological scores (HS) and the serum TNF-α and colonic mucosa IL-1β, IL-6 levels significantly increased (P<0.05 or P<0.01). In the MSD and SASP groups, the ulcer area significantly reduced, and edema disappeared. The CMDIs, HS, the serum TNF-α and colonic mucosa IL-1β, IL-6 levels in the MSD and SASP groups significantly decreased (P<0.05 or P<0.01) compared with the model group. The CMDIs in the MSD group were lower than that in the SASP group (P<0.05), but there were no significant differences in HS, serum TNF-α or colonic mucosa IL-1β, IL-6 levels between the MSD and SASP groups.</p><p><b>CONCLUSION</b>MSD enema can improve colonic mucosa impairment and decrease serum TNF-α and colonic mucosa IL-1β, IL-6 levels in experimental UC.</p>
