Objective:To explore the relationship between the worker-occupation fit and occupational stress in nurses.Methods:Convenience sampling method was used to collect 1 463 nurses from one general hospital and three specialized hospitals from July to October 2019. Depression-anxiety-stress scale (DASS-21) was used to assess the level of occupational stress. Pearson correlation and multivariate logistic regression model were used to analyze the relationship between the worker-occupation fit and occupational stress.Results:The average age of 1 463 nurses was (31.8±7.2) years, and 92.3% ( n=1 350) of nurses were female. 47.2% ( n=690) of nurses had occupational stress and the mean score of worker-occupation fit was (34.4±6.1). The worker-occupation fit and occupational stress had a significant negative correlation ( r=-0.472, P<0.001). The moderate and high level of the worker-occupation fit, characteristic fit, need supply fit, and demand ability fit had protective effects on occupational stress based on the outcome of multivariate logistic regression model [ OR(95% CI) were 0.40 (0.28-0.59), 0.16 (0.10-0.24); 0.32 (0.22-0.47), 0.18 (0.11-0.20); 0.33 (0.21-0.52), 0.18 (0.11-0.30); 0.59 (0.37-0.9), 0.54 (0.38-0.78), respectively]. Conclusion:The worker-occupation fit and different types of fit, including characteristic fit, need supply fit, and demand ability fit, could be associated with the occupational stress.

Objective To investigate the relationship between serum cathepsin S (Cat S) and cystatin C(Cys C) expression levels with carotid arterial plaque property in the patients with ischemic stroke(IS).Methods A total of 336 cases of atherosclerotic cerebral infarction were divided into the stable plaque and unstable plaque group according to the carotid arterial ultrasound.Contemporaneous 114 individuals undergoing healthy physical examination served as the control group.Fasting blood was collected from all subjects entering the groups for detecting serum Cat S and Cys C.Results The serum Cat S and Cys C levels and Cat S/Cys C ratio (Cat S/Cys C) had statistically significant difference between the two groups (P＜0.05),moreover the Cat S level in the unstable plaque group of the patients with cerebral infarction was increased compared with that in the stable plaque group,while serum Cys C level was decreased compared with that in the stable plaque group (P＜0.05).The Cat S levels were (75.34-±-15.45)pg/mL and (60.12±18.53)pg/mL and the Cys C levels were (0.73±0.62)mg/L and (0.93±0.53)mg/L,the Cat S/Cys C ratios were (103.68±2.52) and (64.64± 9.24) respectively,the difference between the two groups had statistical significance (P＜0.05).The Spearman correlation analysis showed that the serum Cat S level and Cat S/Cys C ratio had obviously positive correlation with carotid arterial unstable plaque (r=0.498,P＜0.05;r=0.753,P＜0.01);while the level of serum Cys C was negatively correlated with the unstable plaque (r=-0.213,P＜0.05).Conclusion Serum Cat S/Cys C level has a certain correlation with carotid arterial plaque property in ischemic stroke patients,which may become the serological indicators for predicting carotid arterial plaque.

Objective:To analyze the mediating effect of work-occupation fit between occupational stress and anxiety symptoms in medical staff.Methods:Convenience sampling method was adopted to select participants of one general hospital and three specialized hospitals as respondents for a questionnaire survey in Henan Province from October 2020 to January 2021. A total of 2050 medical staff were investigated, and 1988 valid questionnaires were collected, and the effective rate of the questionnaire was 97.0% (1988/2050) . The "Depression-Anxiety-Stress Scale" and "Worker-Occupation Fit Inventory" were used to evaluate the occupational stress, anxiety symptoms and worker-occupation fit level of medical staff, and the mediation effect of work-occupation fit on the relationship between occupational stress and anxiety symptoms was analyzed using a mediating effect model.Results:The average age of the 1988 medical staff was (32.7±7.8) years old, the positive detection rates of occupational stress and anxiety symptoms were 42.5% (845/1988) and 56.7% (1127/1988) , respectively. Anxiety symptoms of medical staff were positively correlated with occupational stress, negatively correlated with worker-occupation fit ( r=0.831, -0.364, P<0.001) , work-occupation fit was negatively correlated with occupational stress ( r=-0.259, P<0.001) . The results of the mediation effect analysis showed that occupational stress had a direct effect on anxiety symptoms ( β=0.677, BCa 95% CI: 0.648-0.707) , and worker-occupation fit ( β=0.047, BCa 95% CI: 0.039-0.056) , characteristic fit ( β=0.089, BCa 95% CI: 0.074-0.104) , need-supply fit ( β=0.075, BCa 95% CI: 0.062-0.089) , and ability-demand fit ( β=0.035, BCa 95% CI: 0.026-0.044) mediated the association between occupational stress and anxiety symptoms in medical staff, with the mediating effect as a percentage of 6.5%, 12.3%, 10.3%, and 4.8%, respectively. Conclusion:Worker-occupation fit has a mediating effect between occupational stress and anxiety symptoms in medical staff, but mainly direct effect.
