With the continuous deepening of the concept of precision diagnosis and treatment for lung cancer, how to achieve higher efficiency and accuracy in the screening, diagnosis, and treatment pathways in clinical practice has become an important issue that urgently needs to be overcome. The current clinical difficulty lies in the fact that despite continuous advancements in imaging and molecular diagnostic technologies, there are still limitations in manual efficiency and subjective experience when it comes to massive data analysis and multi-scale feature extraction. Artificial intelligence (AI), especially algorithm systems based on deep learning, is an innovative technology capable of deeply empowering medical big data. This method utilizes algorithms such as convolutional neural networks, combined with radiomics, pathomics, and multi-modal data fusion analysis, demonstrating immense potential in early precise detection and benign-malignant differentiation of pulmonary nodules, digital pathological subtype recognition and non-invasive prediction of driver genes, precise 3D surgical planning and automatic delineation of radiotherapy target volumes, as well as dynamic risk warning during follow-up. This innovative technology provides a brand-new solution for realizing intelligent and individualized lung cancer diagnosis and treatment models. This consensus, based on the latest evidence from evidence-based medicine and combined with the development trends in the AI field and real-world clinical needs, was ultimately formed by gathering the consensus opinions of multidisciplinary experts in radiology, pathology, thoracic surgery, and other fields. The main content covers the application specifications of AI in the three core scenarios of lung cancer screening, diagnosis, and treatment, the technical standards for data collection and algorithm validation, as well as the ethical and regulatory challenges faced at the current stage. It aims to clarify the applicable boundaries of AI as a clinical auxiliary decision support tool, providing scientific guidance and standardized exploration directions for peers currently engaged in or planning to carry out AI-assisted clinical diagnosis, treatment, and translation of lung cancer.

Sichuan Province is a hilly schistosomiasis-endemic province in China with the highest endemicity and largest coverage. During the period of more than 70 years of integrated control, there are five distinct phases of schistosomiasis control in Sichuan Province, including baseline investigation, Oncomelania hupensis snail control, chemotherapy for both humans and livestock, management of source of Schistosoma japonicum infections, and sustained control and intensified surveillance and early warning, and a package of key interventions are implemented, including environmental modification, snail control with chemical treatment, large-scale chemotherapy for humans and livestock, management of source of S. japonicum infections, intensified integrated control, establishment of an early warning and surveillance system. As a result, schistosomiasis has been eliminated across all 63 disease-endemic counties (cities, districts) in Sichuan Province by June 2025. Government-led multi-sectoral collaborations, science and technology-supported precision control strategies, and a sustainable control model tailored to the ecological and socio-economic conditions in endemic regions are essential to achieving the target of schistosomiasis elimination in Sichuan Province.

This paper systematically analyzes schistosomiasis transmission risks during the elimination stage and reviews the evolution of the schistosomiasis surveillance system in China from a One Health perspective, with a special emphasis on schistosomiasis surveillance and response practices during the elimination stage from a One Health perspective. These practices include precise screening of human schistosomiasis under low-endemicity conditions, systematic monitoring of schistosomiasis in domestic and wild animals, ecological management of Oncomelania snails, and information-coordinated responses. Nevertheless, the current surveillance and response system for schistosomiasis suffers from challenges of insufficient cross-sectoral coordination and complex external environments, which constrain precise schistosomiasis surveillance and response in China. Therefore, it is urgently necessary to integrate coordination mechanisms, empower the surveillance system with technological innovation, improve capacity building, and actively promote diverse social participation in the One Health framework, so as to consolidate current schistosomiasis control achievements and achieve the target for schistosomiasis elimination across China, which may provide a replicable technical model for global zoonoses control.

Chronic post-dissection aortic aneurysms (PDAAs) are severe long-term complications following surgical or medical conservative management of aortic dissection, primarily caused by persistent perfusion of the residual false lumen. The persistent patency of the residual false lumen is the key pathological mechanism leading to adverse distal aortic remodeling, which can result in progressive aortic dilation, increased risk of rupture, and elevated reintervention requirements, significantly affecting patients' long-term prognosis. This article reviews the latest research progress on assessment methods, influencing factors, and intervention strategies for distal aortic remodeling in PDAAs, aiming to provide reference for clinical decision-making.

Objective:To investigate the effect of mast cell-derived chemokine C-C motif ligand 5 (CCL5) on the migration of CD8 + T cells from vitiligo patients under oxidative stress conditions. Methods:From January 2017 to January 2023, 10 patients with progressive segmental vitiligo, 10 patients with non-segmental vitiligo, and 10 healthy individuals were collected from the Department of Dermatology, Xijing Hospital. Skin tissue samples were obtained from the lesions of vitiligo patients and from the normal skin of healthy individuals, with sampling sites including the face, neck, and upper extremities, and toluidine blue staining was performed to analyze the characteristics of mast cells infiltrating the skin lesions. The effect of H 2O 2 treatment on mast cells was investigated in Transwell chambers. Peripheral blood mononuclear cells (PBMCs) from vitiligo patients were added to the upper chamber, while the human mast cell line LAD2 was added to the lower chamber and divided into 4 groups to receive different treatments: untreated group receiving no special treatment, H 2O 2 group pretreated with H 2O 2, H 2O 2 + neutralization antibody group pretreated with H 2O 2 followed by the treatment with CCL5/RANTES-neutralizing antibodies, and H 2O 2 + PF group pretreated with H 2O 2 followed by the treatment with a Janus kinase 3/non-receptor protein tyrosine kinase selective inhibitor PF-06651600. After 6 hours of co-incubation, cell suspensions were collected from the lower chamber. The number of CD8 + T cells was counted using flow cytometry, and the CCL5 level in the cell culture supernatant was detected using enzyme-linked immunosorbent assay. One-way analysis of variance was used to analyze differences among groups, and least significant difference- t test was used for multiple comparisons. Pearson correlation analysis was performed for correlation analysis. Results:In the 200 × magnification field, the numbers of infiltrating mast cells significantly differed among segmental vitiligo lesions, non-segmental vitiligo lesions, and normal skin tissues (15.7 ± 3.3, 20.9 ± 3.9, 7.2 ± 2.9, respectively; F = 8.07, P = 0.002) ; additionally, the number of infiltrating mast cells was significantly higher in the segmental or non-segmental vitiligo lesions than in the normal skin tissues (LSD- t = 3.50, 5.70, P = 0.047, 0.001, respectively), but there was no significant difference between the segmental and non-segmental vitiligo lesions (LSD- t = 2.20, P = 0.293). A significant positive correlation was observed between the number of infiltrating mast cells and that of CD8 + T cells in the vitiligo lesions ( r = 0.82, P = 0.004). The numbers of CD8 + T cells and CCL5 levels significantly differed among the untreated group, H 2O 2 group, H 2O 2 + neutralization antibody group, and H 2O 2 + PF group (CD8 + T cells: 197.0 ± 45.9, 580.4 ± 62.6, 296.0 ± 43.2, 398.6 ± 62.8, respectively; CCL5: 2.2 ± 0.6 pg/ml, 9.9 ± 1.3 pg/ml, 3.4 ± 0.4 pg/ml, 6.33 ± 0.7 pg/ml, respectively; F = 11.03, 17.77, respectively, both P < 0.001) ; additionally, the H 2O 2 group showed significantly increased numbers of CD8 + T cells and CCL5 levels compared with the untreated group, H 2O 2 + neutralization antibody group, and H 2O 2 + PF group (all P < 0.05) . Conclusion:Mast cells may be involved in the pathogenesis of vitiligo under oxidative stress, and mast cell-derived CCL5 appears to contribute to the occurrence and development of vitiligo by affecting CD8 + T cell migration.

Objective:To investigate the mediating role of psychological capital between the perception of decent work and work engagement among Operating Room nurses, and to provide insights for improving their work engagement.Methods:From December 2023 to February 2024, a total of 307 Operating Room nurses from four class ⅢGrade A hospitals in Beijing, Chongqing, Dalian, and Zhuhai were recruited using convenience sampling. Data were collected using a general information questionnaire, Work Engagement Scale, Decent Work Scale, and Nurses' Psychological Capital Scale. Pearson correlation analysis was conducted to examine the relationships among psychological capital, perception of decent work, and work engagement. Structural equation modeling and mediation analysis were performed using AMOS 24.0 software.Results:A total of 307 questionnaires were distributed, and 301 valid responses were collected, with an effective response rate of 98.05%. The mean scores for work engagement, perception of decent work, and psychological capital were (41.01±10.76), (67.30±17.86), and (93.30±15.15), respectively. Work engagement was positively correlated with both the perception of decent work and psychological capital (all P<0.01), and the perception of decent work was positively correlated with psychological capital ( P<0.01). Psychological capital partially mediated the relationship between the perception of decent work and work engagement, with the mediating effect accounting for 62.63%. Conclusions:Psychological capital plays a partial mediating role between the perception of decent work and work engagement among Operating Room nurses. Nursing managers can enhance nurses' work engagement by improving their perception of decent work and strengthening their psychological capital.

PURPOSE: The rate of complications among patients undergoing surgery has increased due to infection with SARS-CoV-2 and other variants of concern. However, Omicron has shown decreased pathogenicity, raising questions about the risk of postoperative complications among patients who are infected with this variant. This study aimed to investigate complications and related factors among patients with recent Omicron infection prior to undergoing orthopedic surgery. METHODS: A historical control study was conducted. Data were collected from all patients who underwent surgery during 2 distinct periods: (1) between Dec 12, 2022 and Jan 31, 2023 (COVID-19 positive group), (2) between Dec 12, 2021 and Jan 31, 2022 (COVID-19 negative control group). The patients were at least 18 years old. Patients who received conservative treatment after admission or had high-risk diseases or special circumstances (use of anticoagulants before surgery) were excluded from the study. The study outcomes were the total complication rate and related factors. Binary logistic regression analysis was used to identify related factors, and odds ratio (OR) and 95% confidence interval (CI) were calculated to assess the impact of COVID-19 infection on complications. RESULTS: In the analysis, a total of 847 patients who underwent surgery were included, with 275 of these patients testing positive for COVID-19 and 572 testing negative. The COVID-19-positive group had a significantly higher rate of total complications (11.27%) than the control group (4.90%, p < 0.001). After adjusting for relevant factors, the OR was 3.08 (95% CI: 1.45-6.53). Patients who were diagnosed with COVID-19 at 3-4 weeks (OR = 0.20 (95% CI: 0.06-0.59), p = 0.005), 5-6 weeks (OR = 0.16 (95% CI: 0.04-0.59), p = 0.010), or ≥7 weeks (OR = 0.26 (95% CI: 0.06-1.02), p = 0.069) prior to surgery had a lower risk of complications than those who were diagnosed at 0-2 weeks prior to surgery. Seven factors (age, indications for surgery, time of operation, time of COVID-19 diagnosis prior to surgery, C-reactive protein levels, alanine transaminase levels, and aspartate aminotransferase levels) were found to be associated with complications; thus, these factors were used to create a nomogram. CONCLUSION Omicron continues to be a significant factor in the incidence of postoperative complications among patients undergoing orthopedic surgery. By identifying the factors associated with these complications, we can determine the optimal surgical timing, provide more accurate prognostic information, and offer appropriate consultation for orthopedic surgery patients who have been infected with Omicron.

OBJECTIVES: Depressive and anxiety disorders are among the most common mental disorders worldwide and are associated with unhealthy lifestyle behaviors. The Life's Simple 7 (LS7) guideline proposed by the American Heart Association aims to reduce cardiovascular risk by improving behaviors such as diet and physical activity, but its impact on mental health is not yet fully clear. This study examined the association between LS7 scores and symptoms of anxiety and depression in adults undergoing routine health examinations. METHODS: Data were collected from individuals who underwent health examinations from May 2015 to December 2024 at the Health Management Center of the Third Xiangya Hospital. All participants completed the LS7 assessments, the Self-Rating Depression Scale (SDS), and the Self-Rating Anxiety Scale (SAS). Participants were categorized into 4 LS7 score groups: Low (≤7), average (8-9), good (10), and excellent (11-14). Those with SDS or SAS≥50 were classified as having mental disorder symptoms; with this group, SAS≥50 indicated anxiety, SDS≥50 indicated depression, and SDS and SAS≥50 indicated comorbid anxiety-depression. Binary logistic regression was used to assess associations between LS7 score and mental symptoms, calculating odds ratio (OR) and 95% confidence interval (CI). A restricted cubic spline (RCS) regression model was used to analyze the dose-response relationship between LS7 score (continuous variable) and the risk of mental symptoms. Nodes were set at the 5th, 35th, 65th, and 95th percentiles of the LS7 score, with the 5th percentile as the reference point. All models were adjusted for covariates such as gender, age, living alone, drinking status, education level, and sleep quality. Logistic regression framework was used to fit and calculate the adjusted OR (aOR) and 95% CI. Nonlinear relationship tests were also conducted. Subgroup analysis was performed to explore the interaction between gender, age, drinking habits, education level, and other factors and the LS7 score in influencing the risk of mental symptoms. RESULTS: A total of 5 449 participants were included; 1 363 (25.01%) had depressive symptoms, 398 (7.30%) had anxiety symptoms, and 259 (4.75%) had comorbid anxiety-depression. The prevalence of mental symptoms decreased significantly as LS7 scores increased. Univariate and multivariate Logistic regression indicated that LS7 score≥8 was protective against mental symptoms. Multivariate Logistic regression demonstrated moderate discriminative ability (AUC=0.672). Among individuals with anxiety, depression, or comorbid symptoms, LS7 score distributions showed a graded decrease from poor to excellent groups. After adjustment, an excellent LS7 score was associated with a 39% lower risk of depression (aOR=0.61, 95% CI 0.47 to 0.78, P<0.001), a 63% lower risk of anxiety (aOR=0.37, 95% CI 0.22 to 0.59, P<0.001), and a 66% lower risk of comorbid anxiety-depression (aOR=0.34, 95% CI 0.17 to 0.62, P=0.001). The AUC values of the anxiety model, depression model, and comorbid anxiety and depression model were 0.632, 0.672, and 0.619, respectively. All models demonstrated moderate discriminatory ability, which was statistically significant, but their capacity to distinguish cases from non-cases was limited. RCS analysis confirmed a linear inverse relationship between LS7 score and mental symptom risk. Not smoking and regular physical activity were the strongest protective behaviors. Subgroup analysis suggested stronger protective effects in men, younger adults (≤60), non-drinkers, and those with higher education levels, and revealed a significant interaction between alcohol use and LS7 score (P for interaction=0.021), indicating that alcohol consumption may weaken the protective effect of LS7. CONCLUSIONS Ideal healthy lifestyle behaviors, as reflected by higher LS7 scores, are associated with lower risks of anxiety and depression in adults. Promoting LS7-based lifestyle practices may serve as a practical and effective strategy for the prevention and management of anxiety and depression in both clinical and daily life settings.
