Objective: To explore the relationship between sleep quality and executive function among middle school students, so as to provide theoretical support for the promotion of adolescents physical and mental health development. Methods: From September to December 2023, 5 713 junior and senior high school students aged 13 to 18 were selected by stratified cluster random sampling method from Shanghai, Suzhou, Taiyuan, Wuyuan, Xingyi, and Urumqi. Pittsburgh Sleep Quality Index was used to conduct sleep quality survey. And conduct executive function was tested on middle school students, including inhibitory function, refresh function and conversion function tests. Spearman correlation and linear regression were used to analyze the relationship between sleep quality and executive function of middle school students. Results: The total Pittsburgh Sleep Quality Index (PSQI) score of boys was [4.0(2.0,6.0)] and that of girls was [5.0(3.0,6.0)], and the difference was statistically significant ( Z=-10.90, P < 0.01 ). The total PSQI score of boys was positively correlated with both 2-back reaction time and conversion function of executive function ( r =0.04, 0.04); the total PSQI score of girls was negatively correlated with 2-back reaction time ( r =-0.04) ( P <0.05). After controlling for variables such as mental health, physical activity and nutritional status,linear regression analyses showed that PSQI total score of middle school students was positively correlated with the inhibitory function and the conversion function response time [ B (95% CI )=1.28(0.21-2.34), 7.62(2.34-12.90), P <0.05]; the associations of total PSQI scores among middle school students with both 2-back and 1-back response time were not statistically significant [ B (95% CI )=-5.88(-16.14-4.37), 8.05( -3.39 -19.50), P >0.05]. Conclusion Positive correlations are observed on sleep quality with inhibitory and conversion functions of executive function among middle school students.

Based on the theories of "pathogenesis caused by constraint emotions" and "visceral orifices"， it is believed that the pathogenesis of tinnitus caused by constraint syndrome follows the evolution pattern of "qi constraint （liver qi constraint） → fire disturbance （liver constraint transforming into fire） → deficiency impairment （liver constraint with spleen deficiency） → blood stasis （liver constraint leading to blood stasis）". The treatment is guided by the principle of integrated internal and external therapy with harmonization of both body and mind. Internally， the treatment focuses on rectifying zang-fu imbalances， primarily using the Xiaoyao Powder （逍遥散）， with modifications based on syndrome differentiation. External therapies aim to unblock the meridians and orifices， commonly using auricular acupressure and Chinese herbal hot compresses. Additionally， traditional Chinese five-tone music therapy is applied to regulate emotional and mental disturbances. By integrating these three approaches， a comprehensive treatment strategy is formed that harmonizes both body and mind for managing tinnitus associated with constraint syndrome.

OBJECTIVE: To investigate the effects of Danmu Extract Syrup (DMS) on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice and explore the mechanism. METHODS: Seventy-two male Balb/C mice were randomly divided into 6 groups according to a random number table (n=12), including control (normal saline), LPS (5 mg/kg), LPS+DMS 2.5 mL/kg, LPS+DMS 5 mL/kg, LPS+DMS 10 mL/kg, and LPS+Dexamethasone (DXM, 5 mg/kg) groups. After pretreatment with DMS and DXM, the ALI mice model was induced by LPS, and the bronchoalveolar lavage fluid (BALF) were collected to determine protein concentration, cell counts and inflammatory cytokines. The lung tissues of mice were stained with hematoxylin-eosin, and the wet/dry weight ratio (W/D) of lung tissue was calculated. The levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-6 and IL-1 β in BALF of mice were detected by enzyme linked immunosorbent assay. The expression levels of Claudin-5, vascular endothelial (VE)-cadherin, vascular endothelial growth factor (VEGF), phospho-protein kinase B (p-Akt) and Akt were detected by Western blot analysis. RESULTS: DMS pre-treatment significantly ameliorated lung histopathological changes. Compared with the LPS group, the W/D ratio and protein contents in BALF were obviously reduced after DMS pretreatment (P<0.05 or P<0.01). The number of cells in BALF and myeloperoxidase (MPO) activity decreased significantly after DMS pretreatment (P<0.05 or P<0.01). DMS pre-treatment decreased the levels of TNF-α, IL-6 and IL-1 β (P<0.01). Meanwhile, DMS activated the phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) pathway and reversed the expressions of Claudin-5, VE-cadherin and VEGF (P<0.01). CONCLUSIONS DMS attenuated LPS-induced ALI in mice through repairing endothelial barrier. It might be a potential therapeutic drug for LPS-induced lung injury.

Background Occupational stress is an important factor affecting the health of working population, wellness is a topic that has received much attention in recent years, and sleep quality and wellness have a certain impact on occupational stress. Objective To understand the current situation of occupational stress among locomotive engineers in in the Yangtze River Delta, explore the influence of well-being and sleep quality on occupational stress, and provide a theoretical basis for occupational stress intervention among locomotive engineers. Methods Sampling was conducted from October to December 2022 using stratified random sampling. The Chinese version of the Brief Occupational Tension Questionnaire based on the Job Demand-Control Model (JDC model), the World Health Organization 5-item Well-Being Index (WHO-5), and the Pittsburgh Sleep Quality Index (PSQI) scale were used to investigate the occupational stress, well-being, and sleep quality of locomotive engineers. Logistic regression was used to analyze the effects of sleep quality and well-being on occupational stress, and additive and multiplicative interaction models were applied to evaluate the interactive effects of well-being and sleep quality on occupational stress. Results A total of 8243 questionnaires were collected from five locomotive companies, and after excluding unqualified questionnaires, a total of 7976 questionnaires were included in the analysis. The number of locomotive engineers in the Yangtze River Delta reporting positive occupational stress was 4633 (58.09%), the number of low-level well-being was 4949 (62.05%), and the number of poor sleep quality was 4129 (51.77%). The distribution of occupational stress varied by age, length of service, region, technical level, nature of vehicle, education, per capita monthly family income, marital status, smoking, drinking, number of exercise sessions per week, quality of sleep, work shifts, and length of commute (P<0.01). The results of logistic regression showed that a lower level of occupational stress was associated with >11000 yuan per capita monthly household income (OR=0.795, 95%CI: 0.656, 0.964), high level of well-being (OR=0.477, 95%CI: 0.430, 0.528), and good sleep quality (OR=0.588, 95%CI: 0.531, 0.651); a higher level of occupational stress was associated with night shifts: 1 or fewer night shifts (OR=1.707, 95%CI: 1.312, 2.221), 2 to 3 night shifts (OR=2.649, 95%CI: 2.111, 3.325), and 4 or more night shifts (OR=2.804, 95%CI: 2.202, 3.571); a higher level of occupational stress was associated with 60 min or more commuting time (OR=1.353, 95%CI: 1.111, 1.646). Regarding interaction between poor sleep quality and low well-being on occupational stress, the relative excess risk ratio (RERI), attributable risk index (API), and synergy index (SI) were 1.451 (1.059, 1.844), 0.417 (0.327, 0.507), and 2.407 (1.787, 3.241), respectively, and the result of the multiplicative interaction was an OR of 1.546 (95%CI: 1.262, 1.893). Conclusion The prevalence of occupational stress among locomotive engineers in the Yangtze River Delta region is generally at a medium level compared with other industries. Good sleep quality reduces the risk of occupational stress to a greater extent than high well-being, and poor sleep quality and low well-being can interact and further increase the risk of occupational stress.
