Objective:To formulate a community teacher standard for the training of general practitioner program (direction in hospice care).Methods:This was a qualitative study. Twenty-nine experts in general practice and hospice care from various teaching hospitals and community health service centers were invited to participate in two rounds of Delphi consultation from April to August 2022. Based on the results of the consultation, a standard for community faculty training in comprehensive care and end-of-life care for general practitioners was formulated, and the weight coefficients of the indicators were calculated.Results:Of the 29 experts, 11 (37.9%) were male, their age was (52.9±8.9) years, and their working life was (17.0±7.2) years. In the two rounds of expert consultation, the expert positive coefficient was 100.0% (29/29) and 96.6% (28/29), the expert authority coefficient was 0.789 and 0.851, and the expert opinion coordination coefficient W of the importance of all indicators was 0.124 and 0.131, respectively ( χ2=123.01, 131.71, P<0.05). Finally, a set of community-based teacher standard for general practitioner specialty training (direction in hospice care) was established, which consisted of 4 first-level indicators and 30 second-level indicators. The four first-level indicators were basic literacy, clinical qualification and ability, teaching qualification and ability, and scientific research ability, all with the weight coefficients of 0.254, 0.254, 0.252 and 0.240, respectively. Conclusion:The standard of teachers in the community base of general practitioner specialty training (direction in hospice care) established in this study is more scientific, which is conducive to the comprehensive evaluation of teachers in the community training base.

Objective:To construct a set of admission evaluation indicators for terminal patients in community hospice wards.Methods:This qualitative study employed a mixed-methods approach. From January to June 2023, 10 physicians working in community hospice wards in Shanghai participated in one-on-one, semi-structured, in-depth interviews. Based on the interview findings and literature review, a preliminary set of admission evaluation indicators was drafted. Subsequently, from July to December 2023, 18 national experts in hospice/palliative care were selected for a two-round Delphi expert consultation to refine the indicators. The final indicator system was established based on the consultation results, and the weight coefficients for each indicator were determined.Results:Sixteen experts completed both rounds of consultation. The experts had a mean age of (52.0±8.3) years and a mean working experience of (14.4±6.8) years. The response rates for the two rounds were 88.9% and 100.0%, respectively. The authority coefficients were 0.875 and 0.894, and the Kendall′s W coordination coefficients were 0.338 (χ2=471.737, P<0.001) and 0.349 (χ2=398.230, P<0.001), respectively. After two rounds of Delphi consultation, a final admission evaluation indicator system was established, comprising 4 first-level indicators and 63 second-level indicators. The first-level indicators and their weight coefficients were: Underlying Disease (0.256 7), Survival Prognosis (0.256 7), Holistic Needs (0.256 6), and Social Environment (0.240 0). Conclusion:The admission evaluation indicator system for terminal patients in community hospice wards developed in this study facilitates the standardized development of community hospice/palliative care services and contributes to providing high-quality care for patients and their families.

Objective To explore the application value of artificial intelligence in medical research assistance, and analyze the key paths to achieve precise execution of model instructions, improvement of model interpretation completeness, and control of hallucinations. Methods Taking esophageal cancer research as the scenario, five types of literature including research articles, case reports, reviews, editorials, and guidelines were selected for model interpretation tests. The model performance was systematically evaluated from five dimensions: recognition accuracy, format accuracy, instruction execution accuracy, content reliability rate, and content completeness index. The performance differences of Ruibin Agent, GPT-4o, Claude 3.7 Sonnet, DeepSeek V3, and DouBao-pro models in medical literature interpretation tasks were compared. Results A total of 15 studies were included, with 3 studies of each type. The five models collectively conducted 1 875 tests. Due to the poor recognition accuracy of the editorial type, the overall recognition accuracy of Ruibin Agent was significantly lower than other models (92.0% vs. 100.0%, P＜0.001). In terms of format accuracy, Ruibin Agent was significantly better than Claude 3.7 Sonnet (98.7% vs. 92.0%, P=0.002) and GPT-4o (98.7% vs. 78.9%, P＜0.001). In terms of instruction execution accuracy, Ruibin Agent was better than GPT-4o (97.3% vs. 80.0%, P＜0.001). In terms of content reliability rate, Ruibin Agent was significantly lower than Claude 3.7 Sonnet (84.0% vs. 92.0%, P=0.010) and DeepSeek V3 (84.0% vs. 94.7%, P＜0.001). In terms of content completeness index, the median scores of Ruibin Agent, GPT-4o, Claude 3.7 Sonnet, DeepSeek V3, and DouBao-pro were 0.71, 0.60, 0.85, 0.74, and 0.77, respectively. Conclusion Ruibin Agent has significant advantages in terms of formatted interpretation of medical literature and instruction execution accuracy. In the future, it is necessary to focus on optimizing the recognition ability of editorial types, strengthening the coverage ability of core elements of various types of literature to improve interpretation completeness, and improving content reliability through optimizing the confidence mechanism to ensure the rigor of medical literature interpretation.

Objective:To analyze the abnormal results of health surveillance for workers exposed to dimethylformamide (DMF), and to provide reference for the formulation of relevant policies and standards.Methods:In April 2024, 11, 224 workers who participated in occupational health examinations in Jiangsu Province in 2023 were selected as the research subjects. Among them, 5, 615 people exposed to DMF were taken as the exposure group, and 5, 609 people not exposed to hepatotoxic chemicals were taken as the control group. By inquiring about related symptoms and combining with the occupational health examination of workers, the abnormal rates of blood pressure, blood routine, urine routine, electrocardiogram, liver function and B-ultrasonography of the survey subjects were statistically analyzed.Results:Compared with the control group, the abnormal detection rates of indicators such as blood pressure, blood routine, urine routine, and electrocardiogram were higher, and the difference was statistically significant P<0.05). The abnormal rates of various liver function indicators in the DMF exposure group were all higher than those in the control group. Among them, the abnormal rates of alanine aminotransferase, total protein, total bilirubin, and liver B-ultrasound in the exposure group were all higher than those in the control group, and the differences were statistically significant ( χ2=34.88, 42.49, 43.07, 55.28, P<0.001). Compared with the control group, the detected values of alanine aminotransferase, total protein and total bilirubin in the DMF exposure group were higher, and the difference was statistically significant ( F=5.367, 29.543, 37.766, P<0.05). In the DMF exposure group, the abnormal rates of liver function, electrocardiogram and liver B-ultrasound in men were much higher than those in women, and the differences were statistically significant ( χ2=185.05, 10.06, 141.94, P<0.001, P=0.002, P<0.001). Grouped by length of service, the abnormal detection rate of liver function was similar in each length of service segment, and the difference was not statistically significant ( χ2=0.34, P>0.05). The abnormal detection rate of electrocardiogram increased with the increase of length of service, among which it was the highest in the 10-20 years of service, and the difference was statistically significant ( χ2=7.26, P=0.026). The abnormal rate detected by liver B-ultrasound significantly increased with the increase of working years, and was the highest in the section of ≥20 years of working years. The difference was statistically significant ( χ2=44.15, P<0.001) . Conclusion:Occupational exposure to DMF can affect the health of workers, especially increasing the detection rate of abnormal liver function and liver B-ultrasound. It is very important to strengthen the occupational health monitoring of personnel exposed to DMF, improve the working environment, and pay attention to the chronic liver damage caused by DMF occupational exposure to workers.

Objective:To analyze the association between healthcare workers mental health,institu-tional supplies and facilities,inter-organizational coordination during infectious disease outbreaks,and the healthcare institution resilience.Methods:An online questionnaire survey was conducted among the healthcare workforce from 146 institutions in Beijing from January 13,2023 to February 9,2023,and a total of 1 434 eligible respondents were included.The sample comprised 408 responses from tertiary hos-pitals,117 from secondary hospitals,and 909 from primary care institutions.The resilience indicator for healthcare institutions was defined as the degree to which medical services met patient demands,with in-fluencing factors including physical factors,such as material shortages and facility space adaptation or ex-pansion,organizational factors such as information sharing and patient referral,and psychological factors were evaluated using job satisfaction(extrinsic satisfaction,intrinsic satisfaction),burnout(emotional exhaustion,depersonalization,reduced personal accomplishment),and depression status.Ordered mul-ticlassification Logistic regression was used to examine the impact of various factors on the degree to which healthcare services met patient needs;additionally,demographic factors that might influence institutional resilience were controlled.Results:During the emergency response phase,93％of hospitals maintained the capacity to meet patient needs,though tertiary hospitals demonstrated significantly higher rates of service inadequacy(21.05％).Material shortages were reported across all institutions,with tertiary hos-pitals experiencing more frequent multi-item shortages.Inter-institutional collaboration patterns revealed substantial variation:87.50％of primary care facilities,42.86％of secondary hospitals,and 31.58％of tertiary hospitals.Healthcare workers across all levels reported mild depressive symptoms and moderate-to-severe burnout levels.Regression analysis showed high satisfaction(overall satisfaction β=0.04,ex-trinsic satisfaction β=0.06,and intrinsic satisfaction β=0.08),low degree of job burnout(emotional exhaustion β=-0.04,depersonalization β=-0.07 and reduced personal accomplishment β=0.01),low degree of depression(β=-0.06)were significantly associated with higher healthcare institution re-silience.In addition,material shortages were significantly associated with lower resilience,and renova-tion and expansion of treatment spaces,and information sharing,were all associated with higher resilience.Demographic factors(age,gender,marital status,educational background,etc.)had no sig-nificant impact on resilience.Conclusion:Mental health status significantly influences healthcare institu-tion resilience.As human resources constitute the core asset of healthcare institutions,strategic optimiza-tion of workforce allocation and psychological support interventions can effectively strengthen resilience.Moreover,healthcare institution resilience is positively impacted by orderly material supply chains,timely resource distribution,and adaptive reconfiguration of clinical spaces.Finally,facilitating information sharing also enhances institutional resilience.

Objective To analyze the effects of different traction sites and directions on the maxilla and upper dentition when using clear aligners combined with protraction for the treatment of maxillary deficiency.Methods A three-dimensional(3D)finite element model including the zygomaticomaxillary complex,maxillary dentition,and clear aligners was constructed.The models were divided into Group 1(traction hook at the distal of the lateral incisor)and Group 2(traction hook at the distal of the canine).Each group was analyzed under four loading conditions with protraction angles of 0°,10°,20°,and 30° relative to the occlusal plane.A unilateral protraction force of 500 g was applied.The differences in stress distribution and displacement of the maxillary bone and dentition under different loading conditions were analyzed.Results When the protraction angle was 30°,both groups showed forward and downward displacement of the maxilla,while other angles resulted in counterclockwise rotation.Under the same protraction direction,the total displacement of the maxilla and displacements in all directions in Group 2 were greater than those in Group 1.The upper central incisors in Group 1 showed lingual displacement,which increased with the protraction angle.The maxillary dentition in Group 2 showed forward displacement,with the minimum total and sagittal displacements at a protraction angle of 30°.Stress concentration was mainly observed in the zygomaticomaxillary suture and anterior alveolar bone regions in both groups,decreasing as the protraction angle increased.Conclusions Clear aligners combined with protraction can be applied to skeletal Class Ⅲ patients with mild maxillary deficiency.When the protraction site is located at the distal of the canine with a 30° downward and forward angle to the occlusal plane,the maxilla can achieve ideal forward and downward displacement with the minimum labial movement of the upper anterior teeth.
