ObjectiveTo establish three standardized rehabilitation unit models covering acute, critical and comprehensive recovery stages for traumatic brain injury (TBI) that fit the whole-course characteristics, clarify their multidisciplinary collaborative framework, standardized procedures, and information management system, and verify the clinical effectiveness of this staged rehabilitation unit on long-term functional prognosis and in-hospital complications of TBI patients. MethodsThis study was conducted at two stages: model construction and efficacy verification. At the first stage, TBI rehabilitation units for acute, critical and recovery stages were established in the Department of Neurosurgery, Intensive Care Unit and Department of Rehabilitation Medicine, respectively, with unified multidisciplinary team configuration, standardized assessment and treatment protocols, collaborative workflows, and a dedicated information management system. At the second stage, 324 TBI patients admitted to the newly built rehabilitation units from July, 2023 to July, 2025 were enrolled as the observation group, and 167 TBI patients receiving traditional management from January, 2018 to December, 2022 were retrospectively selected as the control group. The primary outcomes were 1-year post-injury Glasgow Outcome Scale (GOS) and Disability Rating Scale (DRS) scores. Secondary outcomes included the incidence of in-hospital complications and the mean indwelling time of tracheal intubation, gastric tube and urinary catheter. ResultsThe 1-year GOS score was significantly higher (t = -7.836, P < 0.001), and the DRS score was significantly lower (t = -6.742, P < 0.001) in the observation group than in the control group. The overall incidence of complications was significantly lower in the observation group than in the control group (χ² = 18.762, P < 0.001). The incidences of pulmonary infection, urinary tract infection, pressure ulcer, lower extremity venous thrombosis and joint contracture deformity were all significantly reduced (χ² > 4.328, P < 0.05). The indwelling time of tracheal intubation, gastric tube and urinary catheter was significantly shorter in the observation group than in the control group (t > 10.276, P < 0.001). ConclusionThe acute-critical-comprehensive three-stage standardized TBI rehabilitation unit could significantly improve the long-term functional outcomes of TBI patients, reduce the incidence of complications, and shorten the indwelling time of invasive tubes through multidisciplinary collaboration, whole-course standardized management and information-based quality control. This model conforms to the pathological and functional laws of TBI, realizes seamless whole-course connection from acute treatment to recovery rehabilitation, and has good clinical feasibility and promotion value. It can provide evidence-based evidence and practical reference for the homogenized and standardized development of TBI rehabilitation in China.

Objective:To explore the specialty work engagement dilemma among wound therapists in non-specialist clinics, so as to provide a reference basis for improving wound therapists' work engagement and reducing job burnout.Methods:This study was a phenomenological study. Semi-structured interviews with 12 wound therapists in non-specialist clinics from 12 hospitals were conducted between May and July 2024 using purposive sampling. Colaizzi seven-step method was used for data analysis and topic refinement.Results:A total of five themes and 13 sub-themes were extracted, including the role change dilemma (focus dispersion due to transfer of positions in clinical departments, and identity challenges due to adjustment of the field of job posting) , career development dilemma (reduced motivation due to obstacles to in-depth development in specialized fields, and limited conditions for scientific research training and implementation impeding the recognition and return of work) , support environment dilemma (insufficient medical insurance support increased job burden, lack of hospital support reduced work efficiency, lack of team support weakened work focus, poor self-support limited the depth of work engagement, lack of support from patients and their families increased the difficulty of maintaining work motivation) , pros and cons weighing dilemma (unclear delineation of risk and responsibility, difficult to weigh risk and benefit) , dilemma of whole-course management of disease (lack of communication between hospitals weakened the continuity of work, lack of home follow-up increased the uncertainty of the work) .Conclusions:Specialty work engagement dilemmas among wound therapists in non-specialist clinics are influenced by a variety of factors. It is necessary for medical institutions, healthcare workers and patients' families to work together to create a favorable working environment for wound therapists in order to promote the high-quality development of wound therapy nursing services in China.

Objective To establish a prediction model for the occurrence of non-occupational carbon monoxide poisoning events in Beijing, and to provide scientific basis and theoretical support for the prevention and warning of poisoning events. Methods Based on the monitoring data of non-occupational carbon monoxide poisoning events in Beijing from 2016 to 2024, the seasonal ARIMA model and seasonal index model were established to analyze the data and predict the occurrence of events. Results Between 2016 and 2024, a total of 436 cases of non-occupational carbon monoxide poisoning were reported in Beijing, showing a downward trend. The established SARIMA model and seasonal index model were SARIMA (1,0,0) (1,1,0) 12, Yt = (-0.0339t+5.8863) × St, and the average relative errors were 65.42% and 29.19%, respectively. In terms of months, the SARIMA model had better predictive performance during April and summer (June to August), while the seasonal index model was superior in other months. By combining the two models, the predicted number of events in 2025 was as follows: 3, 2, 2, 3, 1, 5, 2, 7, 1, 1, 1, and 2. Conclusion The seasonal index model has the best prediction effect on the non-occupational carbon monoxide poisoning events in Beijing throughout the year, and the number of summer events predicted by SARIMA model is closer to the actual values. The two models can be combined to predict the trend of non-occupational carbon monoxide poisoning, which provides a scientific basis for the prevention and control of carbon monoxide poisoning in the future.

Objective:To investigate the diagnostic and prognostic value of systemic immune inflammatory index (SII) for severe traumatic brain injury secondary to acute lung injury (sTBI-ALI).Methods:A retrospective study was conducted on patients with severe traumatic brain injury admitted to the trauma center of the First Affiliated Hospital of Soochow University from January 2021 to November 2023. Patients received standard treatments including hemostasis and intracranial pressure management. Vital signs and blood routine data were collected upon admission. Patients were categorized into sTBI group and sTBI-ALI group based on established clinical diagnostic criteria for ALI to evaluate the diagnostic utility of SII. Subsequently, within the sTBI-ALI group, patients were stratified into survival and non-survival groups based on their 30-day outcomes to assess the prognostic value of SII.Results:A total of 260 sTBI patients were enrolled, of whom 113 developed ALI. Among the sTBI-ALI patients, 73 survived at 30 days. Compared to the sTBI group, the sTBI-ALI group exhibited significantly higher respiratory rates, heart rates, white blood cell counts, neutrophil counts, platelet counts, and SII levels (all P<0.05). Multivariate logistic regression analysis showed that SII index ( OR=1.003, 95% CI: 1.002-1.004, P<0.001) was an independent risk factor for ALI development in sTBI patients. The combined predictive model incorporating SII and heart rate yielded an AUC of 0.801 (95% CI: 0.740-0.862). The non-survival group had significantly higher neutrophil counts and SII levels, and significantly lower Glasgow Coma Scale scores than the survival group (all P<0.05). Multifactorial regression analysis indicated that SII index ( OR=1.002, P=0.004, 95% CI: 1.000-1.003) served as an independent risk factor for 30-day mortality in sTBI-ALI patients. The combined predictive model of SII and GCS achieved an AUC of 0.904 (95% CI: 0.848-0.960). Conclusions:SII demonstrates potential as a biomarker for predicting the development of ALI following sTBI. Furthermore, incorporating SII into predictive models significantly enhances the ability to forecast mortality risk in sTBI-ALI patients.

Objective:To investigate the clinical, pathological, and molecular biological characteristics of gastric hepatoid adenocarcinoma (HAS) in order to provide reference for clinical treatment.Methods:Thirty-two patients diagnosed with hepatoid adenocarcinoma after radical gastrectomy for gastric cancer at Shanxi Cancer Hospital were included from January 2019 to December 2021. Immunohistochemistry, in situ hybridization, and next-generation sequencing (NGS) methods were used to analyze immune markers and molecular characteristics in the pathological tissues from 32 patients with HAS. Cox regression analysis and Kaplan-Meier method were used to analyze the prognostic factors of overall survival and disease-free survival.Results:Among the 32 patients with HAS, 26 were male, 6 were female; aged 28-77 years, with an median age 62.0 (53.8, 67.2) years. Fifteen cases of HAS were located in the cardia, 10 cases in the antrum, and 7 cases in the body of the stomach. The maximum diameter of the mass was 3-10 cm, and mainly ulcerative in gross. The immunohistochemistry and in situ hybridization results showed that the positive rates of AFP, SALLA4, and Glypican-3 were 68.8% (22/32), 68.8% (22/32), 78.1% (25/32), respectively; Seven patients had microsatellite status of dMMR. Two cases of HER2 gene amplification and 2 cases of EB virus positivity. The NGS results showed that HAS was often accompanied by multiple gene mutations, with 23 cases having ≥ 2 gene mutations and 6 cases having ≥10 gene mutations. The TP53 gene had the highest mutation frequency; 4 cases had genetic structural variations; 28 cases had copy number variation. In addition, there were 7 cases of MSI-H and 9 cases of TMB-H. Follow-up results showed that 12 cases died, 9 cases developed metastasis, and the shortest survival time was 5 months.Conclusions:Gastric HAS is a type of tumor with high invasiveness and poor prognosis. The combined detection of AFP, SALLA4 and Glypican-3 can improve the diagnostic rate of tumors. dMMR/MSI-H and TMB-H patients in HAS are significantly higher than those in ordinary gastric cancer, and the high frequency mutation genes in HAS are often accompanied by multiple potential therapeutic targets. Immunotherapy combined with chemotherapy and targeted therapy are expected to become the treatment direction of HAS.

Gastric cancer is a high-incidence malignancy that poses a serious threat to public health in China, ranking among the top three cancers in both incidence and mortality. The majority of patients are diagnosed at an advanced stage, resulting in limited treatment options and poor prognosis. To address key challenges in gastric cancer diagnosis and treatment, a research team led by Professor Jiafu Ji at Peking University Cancer Hospital has focused on the project "Development and Dissemination of Precision Medicine Approaches in Gastric Cancer Management". Through a series of high-quality multicenter clinical studies, the team established a set of new international standards in perioperative treatment, individua-lized drug selection, intelligent noninvasive diagnostics, and novel immunotherapy strategies. These advances have significantly improved treatment efficacy and reduced surgical trauma, achieving key technological breakthroughs in diagnosis, therapy, and mechanistic understanding, and systematically enhancing outcomes for gastric cancer patients. The project ' s findings had a broad international impact, including hosting China ' s first International Gastric Cancer Congress. Through nationwide dissemination, they have promoted the development of precision diagnosis and treatment of gastric cancer as a discipline, and led the formulation of the National Health Commission's guidelines for gastric cancer diagnosis and treatment. In recognition of its achievements, the project was awarded the First Prize of the 2024 Chinese Medical Science and Technology Award.
