Objective:To investigate the survival outcomes and prognostic factors in patients undergoing radical resection for pancreatic body and tail cancer.Methods:A retrospective case series study was conducted on 992 patients who underwent radical resection for pancreatic body and tail cancer at the Pancreatic Center of the First Affiliated Hospital of Nanjing Medical University from January 2016 to June 2024. In this study, 577 (58.2%) were male and 415 (41.8%) were female,with an age of (65±9) years (range: 26 to 86 years). Follow-up continued until June 2024. Survival rates were estimated using the Kaplan-Meier method,and prognostic factors were identified using univariate and multivariate Cox proportional hazards models.Results:Among 992 patients,open surgery was the predominant approach (89.1%, 884/992), and radical antegrade modular pancreatosplenectomy (RAMPS) was performed in 317 patients (32.0%). Combined organ resection,venous resection,and arterial resection were performed in 23.5%, 9.3%,and 11.2% of patients,respectively. The rates of R0, R1-1 mm, and R1-direct resections were 49.8% (494/992),41.5% (412/992), and 8.7% (86/992),respectively. Stage ⅡB was the most common TNM stage (32.2%,319/992). A total of 801 patients (80.8%) received adjuvant chemotherapy. The median follow-up period was 32.0(8.8) months(range:3.2 to 105.3 months),during which 508 patients (51.2%) died. The overall median survival (OS) was 26.4 months,with 1-,3-, and 5-year survival rates of 79.0%,40.0%, and 29.0%, respectively. In the recent five years (from 2020 to 2024), the median OS improved significantly to 34.1 months compared to 20.0 months from 2016 to 2019 ( P<0.01). Histological subtype analysis showed that the median OS time was 26.7 months for pancreatic ductal adenocarcinoma (PDAC, n=855),58.9 months for invasive intraductal papillary mucinous carcinoma (IPMC, n=32),and 15.7 months for adenosquamous carcinoma of pancreas (ASCP, n=73) ( P=0.001). Among PDAC patients, adjuvant chemotherapy significantly improved survival (29.1 months vs. 14.4 months, P<0.01);in IPMC patients, adjuvant chemotherapy also extended survival (65.7 months vs. 58.9 months, P=0.047). Although ASCP patients receiving chemotherapy had a longer median OS time than those without (18.8 months vs. 8.9 months),the difference was not statistically significant ( P=0.151). Multivariate Cox regression analysis in PDAC patients indicated that adjuvant chemotherapy, R0 resection, T stage,N stage,and tumor differentiation were independent prognostic factors ( P<0.01). The median OS time by TNM stage was:not reached for stage ⅠA, 51.6 months for ⅠB, 25.5 months for ⅡA, 23.7 months for ⅡB, 23.0 months for Ⅲ, and 14.4 months for Ⅳ. The median OS time for R0,R1-1 mm,and R1-direct resections was 34.1,24.7,and 15.7 months,respectively ( P<0.01). Conclusion:Adjuvant chemotherapy,R0 resection,tumor stage,and differentiation are independent prognostic factors for pancreatic body and tail cancer.

ObjectiveTo develop a community-family management model for older adults with mild cognitive impairment (MCI) and to formulate detailed application specifications, and to fully leverage the initiative of communities and families under limited resource conditions, for achieving community-based early detection and early intervention for older adults with MCI. MethodsA systematic literature review was conducted to identify pertinent publications. Corpus-based research methodologies were employed to extract, refine, integrate and synthesize management elements, thereby establishing the specific content and service processes for each stage of the management model. Utilizing the 5W2H analytical framework, essential elements such as management stakeholders, target populations, content and methods for each stage were delineated. The model and its application guidelines were finalized through expert consultation and demonstration. ResultsAn expert evaluation of the management model yielded mean scores of 4.84, 4.32 and 4.84 for acceptability, feasibility and systematicity, respectively. By integrating the identified core elements with expert ratings and feedback, the final iteration of the community-family management model for older adults with MCI was formulated. This model comprised of five stages: screening and identification, comprehensive assessment, intervention planning, monitoring and referral pathways to ensure implementation, and enhanced support for communities, family members and caregivers. Additionally, it included 18 specific application guidelines. ConclusionThe proposed management model may theoretically help delay cognitive decline, improve cognitive function and potentially promote reversal from MCI to normal cognition. It may also enhance the awareness and coping capacity of older adults and their families, strengthen community healthcare professionals' ability to early identify and manage MCI.

Background Patients with pneumoconiosis often have limited disease-related knowledge, insufficient access to health education, and substantial health management needs. Health education may help improve rehabilitation outcomes and quality of life in this population. Objective To evaluate the effects of health education based on the Listen-Establish-Adopt-Reinforce-Name-Strength (LEARNS) model on rehabilitation outcomes, health-related behaviors, and quality of life among pneumoconiosis patients, and provide effective intervention strategies for the rehabilitation management of patients with pneumoconiosis. Methods A randomized controlled trial was conducted. A total of 120 pneumoconiosis patients treated in the Department of Occupational Diseases, Beijing Emergency General Hospital, from November 2024 to February 2025 were enrolled. Participants were randomly assigned to a control group or an intervention group using a random number table method, with 60 patients in each group. The control group received routine pharmacotherapy, whereas the intervention group received a 12-week LEARNS model-based health-education intervention in addition to routine treatment. The 6-Minute Walk Test (6MWT) was used to assess exercise tolerance, and the modified Medical Research Council dyspnoea scale (mMRC) was used to evaluate dyspnoea. The Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) were applied for psychological status assessment. Pulmonary function, including forced expiratory volume in one second (FEV₁) and forced vital capacity (FVC), was measured using spirometry. A self-designed scale was used to evaluate eight health-related behaviors targeted by the health education program. The 36-Item Short-Form Health Survey (SF-36) and Chronic Obstructive Pulmonary Disease (COPD) Assessment Test (CAT) were used to assess quality of life, and the Pittsburgh Sleep Quality Index (PSQI) was adopted to evaluate sleep quality. Results After the 12-week intervention, the control group showed no statistically significant changes from baseline in the measured outcomes(P＞0.05). In the intervention group, exercise tolerance improved significantly, with the 6-minute walking distance increasing from (382.55±19.52) m to (426.84±33.59) m (P＜0.001). Dyspnoea was also alleviated, with the mMRC score decreasing from 1.37±0.66 to 0.96±0.54 (P＜0.001). The CAT score decreased from 18.95±7.03 to 10.67±3.64 (P＜0.001). Significant improvements were observed in anxiety and depression symptoms (P＜0.001), with the SAS score decreasing from 38.85±6.24 to 34.27±2.27, and the SDS score decreasing from 49.01±3.25 to 45.49±3.44. Sleep quality improved significantly, with the PSQI score dropping from 7.89±4.35 to 4.05±2.31 (P＜0.001). All eight health-related behaviors in the intervention group improved significantly after the intervention (P＜0.001), including acquisition of disease-related knowledge (1.87±0.34 vs. 3.13±0.45), participation in health education activities (1.89±0.52 vs. 3.61±0.38), and regular physical exercise (2.37±0.41 vs. 4.17±0.33). All SF-36 domain scores increased significantly (P＜0.05), with the most prominent improvements observed in physical functioning, general health, and vitality. At week 12, all SF-36 domain scores were significantly higher in the intervention group than in the control group (P＜0.05). No statistically significant between-group differences were detected in pulmonary function parameters (P＞0.05). Conclusion LEARNS model-based health education could improve exercise tolerance, dyspnea, psychological status, sleep quality, health-related behaviors, and quality of life among patients with pneumoconiosis, and therefore may be a useful adjunctive strategy for rehabilitation management in patients with pneumoconiosis.

Objective To investigate the association between plasma homocysteine(Hcy)level and coronary artery calcification(CAC)and its clinical predictive efficacy.Methods A total of 172 patients who underwent coronary CT angiography North China University of Science and Technology Affiliated Hospital from April 2019 to May 2021 and CAC score(CACS)＞0 were enrolled.According to the CACS value,the subjects were divided into mild calcification group(n=136)and severe calcification group(n=36),and the clinical characteristics of two groups were compared and analyzed.Multivariate Logistic regression model was used to screen the independent influencing factors of CAC severity,and a prediction model was constructed based on the Hcy detection value.The clinical diagnostic value was evaluated by the receiver operating characteristic(ROC)curve.Results There were significant differences in Hcy,white blood cell count,triglyceride and magnesium ion levels between two groups(P＜0.05).Multivariate Logistic regression analysis showed that Hcy,white blood cell count and magnesium ion level were independent risk factors for the progression of CAC.Furthermore,a regression model based on Hcy was constructed and ROC curve was fitted to evaluate its predictive efficacy.The results suggested that the predictive model had the best performance when the critical value of Hcy was set at 27.4μmol/L:the sensitivity was 55.6％,the specificity was 97.1％,and the area under the curve was 0.765.Conclusion Hcy serves as an independent risk factor for the severity of CAC and can effectively predict the progression of CAC with high accuracy.

Objective: There were associations between emotional abuse and neglect (EAN) and depression, but few studies had tested potential mechanisms underlying these relationships. We aimed to provide insights on how (the mediation role of neuroticism), and under what conditions (the moderator role of psychological resilience), led to a higher level of depression. Methods: This study was a cross-sectional study that used a random cluster sampling method. We randomly selected 3,993 participants from four junior middle schools in northern city of China. Participants were asked to complete four self-reported questionnaires, including the Childhood Trauma Questionnaire, Children Depression Inventory-Short Form, Chinese Big Five Personality Inventory Brief Version, and Chinese Resilience Scale. Results: The results showed that neuroticism mediated the associations between EAN and depression. In addition, the mediating effect of neuroticism was moderated by psychological resilience (p<0.05). Conclusion EAN and neuroticism could have an adverse impact on depression, and psychological resilience could alleviate these negative effects as a moderator. Our model suggested psychological resilience could be a particularly effective intervention point for victims of EAN.

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 explore the therapeutic mechanism of moxibustion in Crohn disease(CD)-associated intestinal fibrosis by observing its effects on the angiotensin-converting enzyme(ACE)/angiotensin Ⅱ(Ang Ⅱ)/angiotensin Ⅱ type 1 receptor(AT1R)axis in CD mouse models.Methods:Six randomly selected male C57BL/6 mice were assigned to a normal group,while the remaining mice were administered 0.1 mL of 2,4,6-trinitrobenzene sulfonic acid via enema to establish a CD intestinal fibrosis model.After successful modeling,the mice were randomly divided into a model group,a moxibustion group,and a Western medication group,with 6 rats in each group.The normal group and the model group only received grabbing without intervention.In the moxibustion group,mild moxibustion was applied to Qihai(CV6)and bilateral Tianshu(ST25)once a day for 10 min each time over 7 consecutive days.The Western medication group was administered mesalazine suspension via oral gavage once a day for 7 consecutive days.At the end of the intervention,the general condition,disease activity index(DAI)score,and gross colon score of mice in each group were evaluated.Hematoxylin-eosin staining was used to observe and score the histological changes in the colon tissue in each group.Masson staining was used to observe colonic fibrosis and the ratio of collagen-positive areas was analyzed;the expression of Ang Ⅱ in the colon tissue was detected by the enzyme-linked immunosorbent assay;immunohistochemistry and real-time quantitative reverse transcription polymerase chain reaction were used to detect the protein and mRNA expression of ACE and AT1R in the colon tissue,respectively;Western blotting was used to detect the expression of transforming growth factor(TGF)-β1 and connective tissue growth factor(CTGF)in the colon tissue.Results:Compared to the normal group,the DAI score,gross colon score,colonic histological score,collagen-positive area ratio,ACE protein and mRNA,Ang Ⅱ protein,AT1R protein and mRNA,TGF-β1 protein,and CTGF protein in the colon tissue in the model group increased significantly(P<0.01).In contrast,the above indicators in both the moxibustion group and the Western medication group reduced significantly compared to the model group(P<0.01 or P<0.05).There was no statistical difference in these indicators between the moxibustion group and the Western medication group(P>0.05).Conclusion:Moxibustion can alleviate intestinal fibrosis in CD mice,and its therapeutic mechanism may be associated with the regulation of colonic ACE/AngⅡ/AT1R axis.

Objective To explore the impact of national volume-based procurement policies on the use of medicines in treatment of benign prostatic hyperplasia （BPH） and provide data support for the rational clinical use of medicines in BPH treatment. Methods Data on the use of BPH treatment medications from 2019 to 2023 were extracted from the Chinese Medicine Economic Information Network （CMEI）, covering 892 hospitals （including 645 tertiary hospitals and 247 secondary hospitals）. The changes in various indicators, including the consumption sum, Defined daily doses （DDDs）, Defined daily dose cost （DDDc）, and the ranking ratio （B/A） of these drugs were analyzed and compared. Results From 2019 to 2023, due to the influence of relevant policies, the overall consumption sums of medicines used in the sample hospitals in BPH treatment showed a trend of decreasing first and then rising steadily. The DDDs showed an overall upward trend, while the DDDc demonstrated a gradual decline. Tamsulosin and finasteride consistently ranked first and second in DDDs. The B/A value for tamsulosin was significantly higher than that of other BPH treatment medications. Conclusion The implementation of national centralized drug volume-based procurement policies and other policies from 2019 to 2023 had effectively reduced the economic burden of patients with benign prostatic hyperplasia. Tamsulosin and finasteride, which had the highest B/A in the two categories of α-blockers and 5α-reductase inhibitors, dominated the market for BPH treatment. The clinical use of BPH treatment medications was relatively rational.
