OBJECTIVE From the perspective of China’s healthcare system， to evaluate the cost-effectiveness of tislelizumab in patients with locally advanced or metastatic squamous or non-squamous non-small cell lung cancer （NSCLC） whose disease progresses or is intolerable after receiving platinum-containing dual chemotherapy in the past. METHODS Rationale-303 research data were used to construct a partitioned survival model. The model period was set to be 21 days and simulated to 120 months. Using quality-adjusted life year （QALY） as a health output index， the incremental cost-effectiveness ratio （ICER） was calculated by discounting cost and health output with a discount rate of 5%. Single-factor sensitivity analysis and probability sensitivity analysis were performed to verify the robustness of the basic analysis results. RESULTS Cost-utility analysis results showed that the ICER of tislelizumab group was 65 653.52 yuan/QALY， compared with docetaxel group. This means that the regimen of tislelizumab was more cost-effective than the docetaxel regimen when the willingness-to-pay threshold （WTP） was 3 times China’s gross domestic product （GDP） per capita in 2023 （268 200 yuan/QALY）. The results of single-factor sensitivity analysis showed that the three parameters that had a greater impact on ICER were the prices of tislelizumab， docetaxel and pemetrexed. The results of the probabilistic sensitivity analysis showed that the probabilities of the above two treatment regimens being cost-effective were both 50% when the WTP threshold was approximately 65 000 yuan/QALY. The probability of tislelizumab regimen being cost- effective was 100% when the WTP threshold was ≥134 000 yuan/QALY. CONCLUSIONS From the perspective of China’s healthcare system， when taking 3 times China’s GDP per capita in 2023 as the WTP threshold， tislelizumab is cost-effective for patients with locally advanced or metastatic squamous or non-squamous NSCLC after receiving platinum-containing dual chemotherapy in the past， compared with docetaxel.

In this work, starting from 4-hydroxycoumarin, three series of 22 coumarin derivatives, among which 8 have not been reported in the literature, were synthesized and their in vitro anti-inflammatory activities and mechanisms of action were preliminarily investigated using mouse macrophage model. The results showed that most of the derivatives could significantly inhibit the production of pro-inflammatory factor NO, with compounds 2e, 2f, 2g, 2h, 2i, 2j, 4e, and 4f showing better anti-inflammatory activity than the positive control drug dexamethasone. Further experiments showed that compounds 2h and 4f significantly inhibited the production of pro-inflammatory factors IL-6, TNF-α and IL-1β in RAW264.7 macrophages, and could, therefore, be used as lead compounds for further studies.

Objective: To explore the interactive mechanisms of middle school students lifestyle with depressive and anxiety symptoms, so as to provide a basis for constructing a precise prevention system of middle school students mental health. Methods: From October to December in 2024, a stratified cluster random sampling method was used to select 6 251 middle school students from Guangxi. The Lifestyle Questionnaire, Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder-7 ( GAD- 7) were used to investigate middle school students lifestyle, depressive symptoms and anxiety symptoms. The relationship of adolescent lifestyle with depressive and anxiety symptoms was analyzed through binary Logistic regression. The network analysis method was used to construct the network of middle school students lifestyle with depressive and anxiety symptoms. Results: A total of 1 690 individuals (27.0%) exhibited depressive symptoms, and 1 071 individuals (17.1%) exhibited anxiety symptoms. Binary Logistic regression analysis revealed that smoking, alcohol consumption, excessive intake of sugary drinks, insufficient vegetable intake, not eating breakfast daily, frequent consumption of fast food, prolonged sedentary time on both weekdays and weekends, insufficient sleep duration on weekdays and weekends, and excessive screen time on weekdays were all associated with depressive symptom ( OR =1.19-2.07) and anxiety symptom ( OR =1.20-1.91) in middle school students(all P ＜0.05). Additionally, excessive screen time on weekends was associated only with depressive symptoms ( OR =1.35, P <0.05). The connection between the lifestyle-depressive symptom cluster was mainly through "breakfast" and "suicidal ideation" (weight=0.31); the connection between the lifestyle-anxiety symptom cluster was mainly through "sedentary time on weekdays" and "uncontrollable worry" (weight=0.34). In the depressive symptom network, "depressed mood" had the highest node strength; in the anxiety symptom network, "uncontrollable worry" had the highest node strength. "Suicidal ideation" was a key bridge node between lifestyle and depressive and anxiety symptoms. Conclusions Unhealthy lifestyles are significant modifiable risk factors for depressive and anxiety symptoms among middle school students. Regular breakfast intake and management of sedentary behavior should be prioritized as important intervention entry points.

Background Enhancing the sense of honor and belonging among medical staff is a key component of establishing a modern hospital management system. Compared to medical staff at general hospitals, medical staff at oncology hospitals are more prone to job burnout, yet few studies in China have focused on job burnout among employees in oncology hospitals. Objective To propose a hypothetical model in which job well-being moderates the relationship between stressors and occupational burnout, to explore how stressors influence burnout and potential moderating role of job well-being, and to provide better understanding of job burnout and motivate employees based on the double-edge sword effect of stressors. Methods A cross-sectional survey was conducted in May 2022 at a tertiary oncology specialty hospital in Chongqing, China. A total of 1 898 medical staff were recruited. Data were collectedthrough four scales including a general information questionnaire, Maslach Burnout Inventory-Human Service Survey, Work Stressor Scale, and Occupational Well-being Scale for Medical Staff. Independent sample t-tests and one-way ANOVA were used for univariate comparisons of job burnout. Pearson correlation analysis was employed to examine the relationships between job burnout, stressors, and job well-being. Hierarchical linear regression was conducted to identify factors influencing job burnout and to examine potential moderating role of job well-being in the relationship between stressors and job burnout. Results A total of 2 123 questionnaires were distributed, with 1 898 valid responses, yielding an effective response rate of 89.4%. The prevalence of job burnout was 60.1%. The correlation coefficient was 0.717 (P<0.001) between stressors and burnout, −0.784 (P<0.05) between job well-being and burnout, and −0.744 (P<0.001) between stressors and job well-being. The quadratic stressors showed a statistically significant effect on burnout (β=0.404, P<0.01). Job well-being positively moderated the relationship between the linear stressors and burnout (β=1.289, P<0.001) and negatively moderated the relationship between the quadratic stressors and job burnout (β=−0.571, P<0.01), explaining 7.1% of the variance. Conclusion Job burnout prevalence is relatively high among employees in oncology hospitals. There is a curvilinear relationship between stressors and job burnout, with job well-being moderating this relationship. From a practical perspective, it is recommended to establish a tiered stress alert system to monitor employees’ stress levels and prevent prolonged exposure to high-pressure conditions. Additionally, improving employees’ job well-being through institutional incentives and developmental support can enhance its moderating role in mitigating the adverse effects of stressors on job burnout. Meanwhile, fostering coordinated responses between organizations and individuals is crucial for strengthening mental health management systems, thereby supporting a healthy, stable, and sustainable development of the healthcare workforce.

Extensive evidence has demonstrated that glucagon-like peptide-1 receptor agonists (GLP-1RAs) can ameliorate obesity. Our previous studies revealed that (Ex-4)₂-Fc, a long-acting GLP-1RA we developed, depends on the leptin pathway to treat obesity. However, the mechanisms linking (Ex-4)₂-Fc and leptin resistance remain largely unclear. To address this question, we explored the mechanism of GLP-1RAs from the perspective of the gut microbiota, as increasing evidence indicates an important link between the gut microbiota and obesity. This study aimed to explore the potential role of the gut microbiota in the treatment of GLP-1RAs. We found that (Ex-4)₂-Fc treatment reshaped obesity-induced gut microbiota disturbances and substantially increased the abundance of Akkermansia muciniphila (Am). In addition, (Ex-4)₂-Fc did not respond well in antibiotic-treated (ATB) Obese mice. Subsequent studies have shown that this defect can be overcome by gavage with Am. In addition, we found that Am enhanced (Ex-4)₂-Fc therapy by producing the metabolite inosine. Inosine regulates the macrophage adenosine A2A receptor (A2A) pathway to indirectly reduce leptin levels in adipocytes Thus, elucidating the role of metabolites in regulating the leptin pathway will provide new insights into GLP-1RAs therapy and may lead to more effective strategies for guiding the clinical use of antidiabetic agents.

Objective:To explore the effect of comfort nursing intervention in hospice care for advanced cancer patients at home, and to provide reference for hospice care for advanced cancer patients at home.Methods:A randomized controlled trial was conducted. A total of 105 patients with advanced cancer who were treated in the Cancer Hospital Affiliated to Harbin Medical University from January to February 2023 were selected as the research objects. According to the random number table, they were divided into control group of 53 cases and intervention group of 52 cases. The control group received routine nursing methods, while the intervention group received comfort nursing interventions on this basis. The intervention lasted for 4 weeks. The changes in palliative care outcomes, quality of life and death anxiety were compared between the two groups before and after intervention.Results:Totally 105 cases were included, 53 cases in the control group and 52 cases in the intervention group. In the control group, there were 25 males, 28 females, aged (58.96 ± 10.71) years old; in the intervention group, there were 22 males, 30 females, aged (59.82 ± 10.53) years old. Before intervention, there was no statistically significant difference in palliative care outcomes, quality of life and cancer death anxiety scores between the two groups of patients (all P>0.05). After intervention, the total score of palliative care outcomes in the intervention group was (13.34 ± 5.88) points, significantly lower than (16.15 ± 5.72) points in the control group, with a statistically significant difference ( t = 2.48, P<0.05). The overall health status score of quality of life was (68.55 ± 9.34) points in the intervention group, higher than (63.01 ± 9.28) points in the control group ( t = 3.05, P<0.05). The total score of cancer death anxiety was (8.85 ± 2.72) points, significantly lower than (10.59 ± 3.14) points of the control group, with a statistically significant difference ( t = 3.04, P<0.05). Conclusions:The application of comfort nursing mode in home based hospice care can improve the quality of hospice care for advanced cancer patients, reduce their level of death anxiety, and is of great significance for improving the quality of life of advanced cancer patients.

Objective:To construct a teaching ability evaluation system for diversified general medicine course teachers under the guidance of "one practice and three learning".Methods:A research group was established to search for relevant documents and literature. A framework of evaluation index system was established through drafting and repeated discussion and modification by members of the group, as well as further discuss and modification by experts in general medicine. The framework was used to develop an expert consultation questionnaire on the teaching ability evaluation system for diversified general medicine course teachers under the guidance of "one practice and three learning". Through two rounds of expert consultation, a teaching ability evaluation system for diversified general medicine teachers under the guidance of "one practice and three learning" was constructed. A questionnaire was developed according to the system. The rationality and scientificity of the evaluation index system were verified by questionnaire survey.Results:The teaching ability evaluation system for diversified general medicine teachers under the guidance of "one practice and three learning" included 3 first-level indicators, 15 second-level indicators, and 41 third-level indicators. The general medicine curriculum evaluation questionnaire developed on the system showed that the Cronbach's α coefficient of the overall evaluation system was 0.981. The Cronbach's α coefficients of first-level indicators, including general medicine teaching plan, diversified theory and practice teaching, and comprehensive ability cultivation under the guidance of "one practice and three learning" ideology, were 0.920, 0.919, and 0.923, respectively. The content validity index (S-CVI) of the system was 0.981, and the content validity index (I-CVI) of indicators were 0.826-1.000. The correlation coefficients of first-level indicators and the system were 0.837-0.942 (all P<0.05). The correlation coefficients of second-level indicators and their corresponding first-level indicators were 0.586-0.971 (all P<0.05). The correlation coefficients of third-level indicators and their corresponding first-level indicators were 0.412-0.904 (all P<0.05). Conclusions:Under the guidance of "one practice and three learning", the teaching ability evaluation indicators for diversified general medicine course teachers have high specificity, rationale structure, high feasibility, high reliability, and high practicability. This evaluation system can provide theoretical reference for the training of undergraduate students in general medicine.

The prefrontal cortex and hippocampus may support sequential working memory beyond episodic memory and spatial navigation. This stereoelectroencephalography (SEEG) study investigated how the dorsolateral prefrontal cortex (DLPFC) interacts with the hippocampus in the online processing of sequential information. Twenty patients with epilepsy (eight women, age 27.6 ± 8.2 years) completed a line ordering task with SEEG recordings over the DLPFC and the hippocampus. Participants showed longer thinking times and more recall errors when asked to arrange random lines clockwise (random trials) than to maintain ordered lines (ordered trials) before recalling the orientation of a particular line. First, the ordering-related increase in thinking time and recall error was associated with a transient theta power increase in the hippocampus and a sustained theta power increase in the DLPFC (3-10 Hz). In particular, the hippocampal theta power increase correlated with the memory precision of line orientation. Second, theta phase coherences between the DLPFC and hippocampus were enhanced for ordering, especially for more precisely memorized lines. Third, the theta band DLPFC → hippocampus influence was selectively enhanced for ordering, especially for more precisely memorized lines. This study suggests that theta oscillations may support DLPFC-hippocampal interactions in the online processing of sequential information.
