What are the Bad Habits and Behaviors of Inconsiderate Doctors in Chinese Inhabitants' Mind? A Cross-Sectional Study.

Purpose: This study aims to 1) investigate inhabitants' perceptions of doctors' inconsiderate behaviors during diagnosis and treatment, 2) explore the factors influencing inhabitants' attitudes toward doctors' professional reputation, and 3) examine the status of doctors' inconsiderate behaviors and inhabitants' attitudes and behaviors toward these doctors in China. Patients and Methods: A cross-sectional online survey was conducted with 2050 participants from over 30 Chinese cities, from March to June 2018. In total, 1598 valid questionnaires were obtained (with an effective response rate of 77.95%). Data were analyzed using descriptive statistics, exploratory factor analysis, and logistic linear regression analysis. Results: We developed a questionnaire comprising of 15 items regarding doctors' inconsiderate behaviors based on inhabitants' perspectives (Cronbach's alpha was 0.944). Additionally, we identified the factors that influence the attitudes of inhabitants regarding doctors' professional reputation, such as frequency of medical consultations, medical expenses, education catalog, and type of medical insurance. A majority of the participants highly valued Chinese doctors' professional reputation (87.55%), and trusted them (86.29%). However, about 60.27% of the participants reported a pessimistic-like judgment on the current doctor-patient relationship (DPR) in China. Participants believed that Chinese doctors received a high income (20.47%), maintained a high social status (23.46%), and had a heavy workload (59.95%). Furthermore, about 54.88% of participants reported that they would not engage in aggressive behaviors against doctors during a dispute. Lastly, about 26.66% of participants reported that they would act rationally when they were dissatisfied with their doctors. Conclusion: Impassive emotions and improper actions of doctors toward patients jointly contributed to the disrepute of Chinese doctors. Although DPR was becoming tense, Chinese inhabitants held a positive evaluation of doctors' professional reputation. While an improvement in the economic situation and reputation of doctors enhanced the DPR, there remains an urgent need to improve the working environment in regard to future Chinese health reforms.

Does abusive supervision lead nurses to suffer from workplace violence? A cross-sectional study.

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 (ß = 0.209, p < .01) and the symptoms of anxiety and depression (ß = 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 (ß = -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.

Contribution of Character Strengths to Psychology Stress, Sleep Quality, and Subjective Health Status in a Sample of Chinese Nurses.

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 < 0.01), professional categories (F = 5.545, P < 0.01), and job tenure (F = 9.470, P < 0.01). The results showed that CSs significantly affected the psychological stress (ß = -0.365, P< 0.01), sleep quality (ß = 0.312, P< 0.01), and subjective health (ß = 0.398, P< 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.

Demographic Factors and Job Characteristics Associated With Burnout in Chinese Female Nurses During Controlled COVID-19 Period: A Cross-Sectional Study.

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 < 0.05,odds ratio [OR] <1), monthly salary income (Waldχ2 = 12.460, P < 0.05, OR <1), and night shift (Waldχ2 = 3.821, P < 0.05, OR > 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.

By field experiment and cultivation simulating, we analyzed the impacts of oilseed rape straw incorporation on root, tiller and grain yield of rice. Results showed that straw incorporation treatments decreased 1-2 in tillers and 1.0-8.6 mg per plant in bleeding sap. The activities of glutamine synthetase (GS), glutamic-pyruvic transaminase (GPT) and glutamic-oxalacetic transa-minase (GOT) of root in straw incorporation treatments were reduced by 0.10-6.11, 0.06-0.31 and 0.52-0.84 µmol·g-1·h-1 respectively as compared to control, during the earlier stage (0-36 d after transplanting) of rice growth. Compared to no straw incorporation treatment, the straw incorporation by plough method increased bleeding sap by 3.4-11.7 mg per plant, and increased the activities of GS, GPT and GOT by 0.34-0.78, 0.13-0.45 and 0.18-0.20 µmol·g-1·h-1 respectively. During the later stage (56 d after transplanting) of rice growth, straw incorporation treatments by mulching reduced bleeding sap by 19-25 mg per plant, and increased the activities of GS, GPT and GOT in root by 0.16-0.34, 0.08-0.21 and 0.06-0.32 µmol·g-1·h-1, respectively. The grain yield of total straw returning treatments (MF2 and FH2) were higher than other straw returning treatments. In comparison of MF2, the rice yield of FH2 was higher by 0.13-0.48 t·hm-2. Oil seed rape straw incorporation hindered rice root growth and delayed the reviving of rice after transplanting, by decreasing the activities of roots and nitrogen metabolizing enzymes during earlier stage. However, it promoted rice root growth by increasing activities of roots and nitrogen metabolizing enzyme during media and later stage. The increase or decrease of rice yield is a comprehensive balance of multiple factors in straw incorporation rice field. Total straw incorporation by plough method is one of the better straw returning manners for oilseed rape-rice rotation system in Sichuan Basin area.

Two new 2-(2-Hydroxy-2-phenylethyl)chromens from agarwood originating from Aquilaria crassna.

Two new 2-(2-hydroxy-2-phenylethyl)chromones (1‒2), along with three known 2-(2-phenylethyl)chromones (3‒5), were isolated from the agarwood originating from Aquilaria crassna Pierre ex Lecomte. Their structures were determined by the spectroscopic methods including 1D and 2D NMR analysis and comparison with reported data in the literature. All the compounds were isolated from agarwood of A. crassna for the first time. Compounds 1 and 2 exhibited inhibitory activity against acetylcholinesterase (AChE) with 17.4 ± 0.6 and 15.8 ± 0.7%, respectively, at a concentration of 50 µg/ml. Besides, Compound 3 expressed antibacterial activities against Ralstonia solanacearum with diameter of the inhibition zone of 6.80 ± 0.08 mm at a concentration of 10 mg/ml.

Emission Spectrometry for the Detection of Methane Based on Gas Ionization Discharge Microplasma at Room Temperature.

A microplasma-generating device was developed by using needle-plate electrode discharge with the incorporation a Pt/carbon nanotube (CNT) nanocomposite-decorated FTO electrode. When an alternating current voltage of 1.32 kV and a low power consumption of 13 W in nitrogen (N2) carrier gas are applied, the system can be applied to detect methane at room temperature. The main characteristic lines were assigned to CH, C2 and Hα during the discharge process of CH4 at room temperature.The emission intensity of C2 at 516 nm is linear with the concentration of CH4 from 0.5% to 4.0% (φ), and the detection limit (S/N=3) is 0.19% (φ). The emission intensity of Hα at 656 nm is linear with the concentration of CH4 from 0.1% to 3.0%(φ)with the detection limit (S/N=3) is 0.03% (φ). The relative standard deviation (RSD) is less than 2% from 11 repetitive analyses using 3.2% CH4. The Pt/CNT nanocomposite-modified FTO electrode exhibited enhanced sensing performance with precise, repeatability and linear correlation compared with that of the pure MWNT/FTO electrode and bare FTO electrode. When CH4 were discharged in air, the emission spectra of CH4 was different from that in N2. It was found that C2 peak was disappeared and the Hα intensity was also liner to the concentration of CH4 in the range of 0.5%～4%. The established system exhibited advantages with small size, simple fabrication and operation at room temperature compared to other detection system.

Three new sesquiterpenoids from agarwood of Aquilaria crassna.

Three new sesquiterpenoids (1-3), together with two known ones were isolated from the EtOAc extract of agarwood originating from Aquilaria crassna. The new compounds were elucidated on the basis of spectroscopic techniques (UV, IR, MS, 1D and 2D NMR). Compounds 1-5 were isolated from agarwood of A. crassna for the first time. In the acetylcholinesterase inhibition experiment of 2-5, compound 3 showed acetylcholinesterase inhibition activity (IR 42.9±0.6%). Compound 5 expressed antibacterial activities against Staphylococcus aureus and Ralstonia solanacearum with diameter of the inhibition zones of 12.35±0.11mm and 16.90±0.09mm, respectively.

The analytical determination and electrochemiluminescence behavior of amoxicillin.

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 H2O2. 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 × 10-8 g/mL to 2.5 × 10-7 g/mL, and the limit of detection (signal/noise = 3) was 5 × 10-9 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.
