Objective To explore the relationship between quality life and TCM constitutions of elderly patients with hypertension in a community in Shanghai; To provide the basis for the suitable and feasible community elderly hypertension management method. Methods Through multistage stratified sampling method, 808 elderly patients with hypertension in the community were investigated for their life quality and TCM constitutions on the basis of inform consent and voluntary participation. The life quality and TCM constitution characteristics as well as the relationship were analyzed by applying the statistic analysis software. Results Among the investigated elderly patients with hypertension in the community, 97.28% cases’ overall life quality was above the middle level and 91.46% cases’ self-evaluated health and quality of life scores were above the middle level. 54.70% cases were gentleness type, and the biased constitution was dominated by qi deficiency, yang asthenia, yin asthenia and phlegmatic hygrosis. The relationship between life quality and TCM constitutions may be existent. If TCM constitutions tended to be gentleness type, the physical score and the psychological score would be higher, which leaded to better quality of life. Conclusion TCM constitution characteristics are associated with quality life of elderly hypertension patients in the community. Intervention targeted on the results of TCM constitution identification would be better to prevent and control hypertension and improve health level and quality of life.

Objective To further investigate the effect of sinomenine (SIN) on TNF-α-induced VCAM-1 expression in human umbilical vein endothelial cells (HUVECs). Methods HUVECs were isolated from freshly collected umbilical cords. Positive control samples were stimulated with TNF-α, but free of SIN. Negative control samples were treated in the same way, but without TNF-α and SIN. Experimental samples were co-cultured with TNF-α and SIN at various concentrations (0.25, 0.5, and 1.0 mol/L), or TNF-α and dexamethasone (Dex) at concentration of 1.0×10-6 mol/L, or TNF-α with Dex (at concentration of 1.0×10-6mol/L) and SIN at different concentrations (0,25, 0.5, and 1.0 mmol/L) (co-treated groups). VCAM-1 expression was detected by flow cytometry (FCM). Results SIN inhibited expression of VCAM-1 in TNF-α-induced HUVECs, the best effect was shown in the 1.0 mmol/L SIN treated group. VCAM-1 decreased more markedly in the co-treated groups. Conclusion SIN inhibits TNF-α-induced VCAM-1 expression on HUVECs in vitro, and SIN maybe synergistic with Dex in inhibiting TNF-α-induced VCAM-1 expression on HUVECs in vitro.

Background At present, domestic research on job burnout and health-related productivity is limited to medical workers, and the impact of job burnout on health-related productivity of enterprise staff deserves attention. Objective To explore the association between job burnout and health-related productivity loss among enterprise staff. Methods A cross-sectional online questionnaire survey was conducted among enterprise staff who were selected from seven enterprises in Minhang District of Shanghai. The Chinese version of Maslach Burnout Inventory-General Survey (MBI-GS) was used to assess job burnout, and a questionnaire based on and modified from the WHO Health and Work Performance Questionnaire was used to assess the loss of health-related productivity. Logistic regression was used to analyze the impact of job burnout on health-related productivity under the control of selected demographic characteristics, socio-economic factors, and occupational factors. Results A total of 3489 questionnaires were recovered, and 3156 valid questionnaires were included in the statistical analysis. Among the 3156 valid questionnaires, 2228 (70.8%) respondents were assessed as suffering from job burnout, in which 1858 (59.0%) were mild to moderate job burnout, and 370 (11.7%) were severe job burnout; the median score (interquartile range) of MBI-GS was 2.18（2.69）, the median rates (interquartile range) of absenteeism and presenteeism were 0.00% (0.00%) and 20.00% (50.00%), respectively. The prevalence of presenteeism significantly varied by gender, education, marital status, working years, job category, exhaustion, cynicism, professional efficacy, and job burnout (P<0.05). The prevalence of absenteeism significantly varied by education, marital status, working years, job category, exhaustion, cynicism, professional efficacy, and job burnout (P<0.05). Job burnout was positively correlated with absenteeism (r=0.157) and presenteeism (r=0.412) (P<0.01). After controlling for selected demographic characteristics, social economic factors, and occupational factors, the logistic regression showed that job burnout was associated with health-related productivity loss, the OR value remained relatively stable, and referring to negative job burnout, the OR (95%CI) of severe job burnout was 6.35 (4.52-8.92). Conclusion Job burnout of enterprise staff has a negative impact on health-related productivity. Severer job burnout associates with higher health-related productivity loss. Enterprises should pay attention to the prevention and control of job burnout to reduce health-related productivity loss.

Background Under the backdrop of the national innovation-driven development strategy, the increasing occupational stress and job burnout among employees are noteworthy for their impact on employees' subjective well-being. Objective To clarify the status, distribution characteristics, and the relationship between subjective well-being, occupational stress, and job burnout of employees in research and development (R&D) enterprises, in order to improve their subjective well-being. Methods A total of 3366 employees from R&D departments at 7 enterprises in Minhang District of Shanghai were selected. The well-being level of the research subjects was investigated by using the World Health Organization Well-Being Index (WHO-5) that yielded total scores from 0 to 25, and a higher total score indicated a higher well-being level; the levels of occupational stress and job burnout were investigated by using the Chinese version of the Job Content Questionnaire, and the Chinese version of the Maslach Burnout Inventory-General Survey (MBI-GS). The scores of WHO-5, JDC, and MBI-GS were incorporated into structural equation modeling (SEM) as numerical variables to analyze their relationship. Results The scores of subjective well-being, occupational stress, and job burnout of employees in the R&D enterprises were 13.30±6.09, 1.12±0.45, and 2.18±1.12, respectively. The positive rates of occupational stress and job burnout were 44.4% and 70.9% respectively, and the positive rate of severe job burnout was 11.7%. There were statistically significant differences in the score of subjective well-being among the participants by gender, age, educational level, marital status, registered residence, working seniority, and jobs (P<0.05); there were statistically significant differences in the positive rate of occupational stress by gender, educational level, marital status, working seniority, and jobs (P<0.05); there were statistically significant differences in the positive rate of job burnout by gender, age, educational level, marital status, registered residence, working seniority, and jobs (P<0.05). There was a negative correlation between subjective well-being and occupational stress (r=−0.1747, P < 0.01), a negative correlation between subjective well-being and job burnout (r=−0.2987, P < 0.01), and a positive correlation between occupational stress and job burnout (r=0.3342, P < 0.01). A structural equation containing partial mediating effect of job burnout on the relationship between occupational stress and subjective well-being was established, and the partial effect accounting for 52.5% of the total effect. Conclusion The job burnout among employees in R&D companies partially mediates the impact of occupational stress on subjective well-being. Reducing the level of job burnout will help alleviate occupational stress and thus improve employees' subjective well-being.

Background Job burnout is an early mental health condition caused by job stress and contributes to many negative effects on work and life. Employees of research and development (R&D) enterprises are exposed to constant pressure from innovation, production speed and sales expansion, and they are prone to burnout symptoms if such factors are not under effective control. Objective To evaluate the current situation of job burnout among employees of R&D enterprises in Minhang District of Shanghai and explore its influencing factors. Methods During November to December 2021, a cross-sectional study was developed and a convenient sampling method was used to enroll employees from 7 R&D enterprises in Minhang District of Shanghai. On the basis of voluntary participation with informed consent, a survey was conducted by using a self-made questionnaire (collecting data about general demographic characteristics, occupational characteristics, behavior and lifestyle), the Chinese version of the Concise Occupational Stress Questionnaire, and the Chinese version of the Maslach Burnout Inventory-General Survey. Occupational stress and its dimensions (job demand, job control, and social support) were divided into high, medium, and low levels according to tertiles. The positive rate of job burnout was reported according to score categorization (<1.5 refers to no job burnout, ≥1.5 refers to job burnout, where ≥1.5 and <3.5 refer to mild and moderate job burnout, and ≥3.5 refers to severe job burnout). Potential influencing factors of job burnout were evaluated by using one-way ANOVA, chi-square test, forward stepwise regression, and non-conditional binary logistic regression (α=0.05, two-sided test). Results A total of 3153 subjects were enrolled and 3014 samples were included in the analysis, with a valid response rate of 95.6%. Among the included subjects, 888 (29.46%) reported no job burnout, 1775 (58.89%) reported mild to moderate job burnout, and 351 (11.64%) reported severe job burnout. The mean of total job burnout score was 2.17±1.12, and the dimentional mean scores were 2.78±1.61 for emotional exhaustion, 1.60±1.60 for cynicism, and 4.05±1.57 for diminished personal accomplishment. Varied categories of sex, age, marital status, working position, sleep status, job demand, job control, and social support groups of workers resulted in significant differences in job burnout score. Compared with the low job demand group, the positive rate of job burnout was elevated in the medium and high job demand groups; the risk of job burnout in the medium job demand group was 1.42 (95%CI: 1.04-1.94) times higher, and that in the high job demand group was 2.64 (95% CI : 2.17-3.22) times higher versus the low job demand group. The risk of job burnout in the medium job control group was 1.35 (95%CI: 1.06-1.72) times higher versus the low job control group. Compared with the low social support group, job burnout was less reported in the other groups, and the OR (95%CI) values of the medium and high social support groups were 0.41 (0.31-0.53) and 0.15 (0.12-0.19) respectively. Conclusion The rate of reporting positive job burnout in R&D enterprises is high, which deserves sufficient attention. Relieving work pressure, increasing job control and social support, and maintaining adequate sleep are helpful to reduce job burnout.
