Aim This study aimed to (1) assess the current status of Chinese nurses' exposure to workplace violence; (2) identify the cluster of interrelationships between abusive supervision, anxiety and depression symptoms, work ability, and workplace violence in nursing settings; and (3) clarify the functional mechanism among these variables. Methods A cross‐sectional survey was conducted online from September to October 2020 in China. A total of 1,221 valid questionnaires were collected across 100 cities in 31 provinces. Results Approximately 67.57% of participants experienced workplace violence in the past one year, in the types of verbal violence (59.71%), made difficulties (43.16%), mobbing behaviour (26.70%), smear reputation (22.52%), physical violence (11.30%), intimidating behaviour (10.16%) and sexual harassment (4.10%), respectively. Moreover, nurses' exposure to workplace violence was significantly and positively influenced by the perceptions of abusive supervision (β = 0.209, p < .01) and the symptoms of anxiety and depression (β = 0.328, p < .01). Anxious and depressive symptoms partly mediated the association between abusive supervision and workplace violence, which were significantly moderated by work ability (β = −0.021, p < .05). Conclusions Our study assesses the prevalence of the seven types of workplace violence against Chinese nurses. Majority of nurses have experienced different types of workplace violence. Nurses who are abused by their supervisor are more likely to develop poor psychological health than those who are not. Moreover, nurses' positive association of abusive supervision with workplace violence is more notable among nurses with lower work ability. Implications of Nursing Management ‘No abusive supervision, no workplace violence’. A harmonious nursing environment needs to be provided to minimize exposure to workplace violence and mental health threats towards nursing staff, which is a key point for hospital administrators and health policymakers. Essential work ability should be developed to reduce the damage of the abusive supervision and workplace violence against nurses.

A novel electrochemiluminescence (ECL) luminophor of amoxicillin was studied and found to generate ECL following the oxidation or reduction of amoxicillin. The amoxicillin oxidation state was also found to eliminate the reduction state, generating ECL. When solutions of amoxicillin were scanned between +1.5 V and -1.0 V with a graphite electrode in the presence of cetyltrimethyl ammonium bromide using KC1 as the supporting electrolyte, ECL emissions were observed at potentials of -0.7 V and +0.5 V. The ECL intensity at -0.7 V was enhanced by HO. Based on these findings, an ECL method for the determination of the amoxicillin concentration is proposed. The ECL intensities were linear with amoxicillin concentrations in the range of 1.8 × 10 g/mL to 2.5 × 10 g/mL, and the limit of detection (signal/noise = 3) was 5 × 10 g/mL. The florescence of amoxicillin had the greatest emission intensity in a neutral medium, with the emission wavelength dependent on the excitation wavelength. The experiments on the ECL mechanism for amoxicillin found that the electrochemical oxidation products of dissolved oxygen and active oxygen species contributed to the ECL process. The data also suggest that the hydroxyl group of amoxicillin contributed to its ECL emission.

Background: To investigate the prevalence of burnout syndrome among Chinese female nurses during the controlled coronavirus disease 2019 (COVID-19) period and explore its associated socio-demographic factors and job characteristics.Methods: With the multistage, stratified sampling method, a cross-sectional online survey was conducted from September to October 2020 in China. The survey tool included revised Maslach Burnout Inventory (MBI) with 15 items, socio-demographic and job characteristics. Univariate logistic regression analysis and multivariate factor logistic regression analysis were used to identify the risk factors for burnout of female nurses.Results: During controlled COVID-19 period in China, the overall prevalence of burnout symptoms among Chinese female nurses was 60.2% with a breakdown in severity as follows: 451 (39.8 %) mild, 163 (14.4%) moderate, and 68 (6.0%) severe burnout. Little variance was reported for burnout symptoms according to job tenure (Waldχ2 = 14.828, P &lt; 0.05,odds ratio [OR] &lt;1), monthly salary income (Waldχ2 = 12.460, P &lt; 0.05, OR &lt;1), and night shift (Waldχ2 = 3.821, P &lt; 0.05, OR &gt; 1).Conclusion: Burnout symptoms among Chinese female nurses were prevalent and associated with job tenure, monthly salary income, and night shift. Female nurses who were with shorter job tenure, worked at night shifts, and had lower monthly salaries tended to exhibit increasing high-level burnout than their counterparts. This study serves as an implication for administrators and policy-makers to improve the work conditions of nurses for promoting overall healthcare service quality.

Objectives: The main objectives of this study were to describe the current state of character strengths (CSs) of nurses; explain how they affect stress, sleep quality, and subjective health status; and reveal the mediating role of stress for the subject matter on the association between CSs, sleep quality, and subjective health status.Methods: A cross-sectional online survey was conducted from September to October 2020 in China. A multistage stratified sampling method was used, and 1,221 valid questionnaires across 100 cities in 31 provinces were collected.Results: For the participants in this survey, the three dimensions of CSs ranging from high to low were caring (4.20 ± 0.640), self-control (3.53 ± 0.763), and inquisitiveness (3.37 ± 0.787). There was difference in CSs scores across age (F = 8.171, P &lt; 0.01), professional categories (F = 5.545, P &lt; 0.01), and job tenure (F = 9.470, P &lt; 0.01). The results showed that CSs significantly affected the psychological stress (β = −0.365, P&lt; 0.01), sleep quality (β = 0.312, P&lt; 0.01), and subjective health (β = 0.398, P&lt; 0.01) of nurses. Moreover, psychological stress partially mediated the association between CSs and both types of health outcomes.Conclusion: In China, the CSs of nurses are at high levels. We find that nurses with high-level CSs are likely to experience less psychological stress and exhibit healthy psycho–physiological responses, which contribute to positive health outcomes. Finally, our study argues that strength-based interventions of positive psychology in hospitals should be provided to minimize threats to the physical and psychological health of health professionals, which is a beneficial choice for future hospital reforms in the domain of occupational health management.
