With the rapid development of artificial intelligence, computational pathology has been seamlessly integrated into the entire clinical workflow, which encompasses diagnosis, treatment, prognosis, and biomarker discovery. This integration has significantly enhanced clinical accuracy and efficiency while reducing the workload for clinicians. Traditionally, research in this field has depended on the collection and labeling of large datasets for specific tasks, followed by the development of task-specific computational pathology models. However, this approach is labor intensive and does not scale efficiently for open-set identification or rare diseases. Given the diversity of clinical tasks, training individual models from scratch to address the whole spectrum of clinical tasks in the pathology workflow is impractical, which highlights the urgent need to transition from task-specific models to foundation models (FMs). In recent years, pathological FMs have proliferated. These FMs can be classified into three categories, namely, pathology image FMs, pathology image-text FMs, and pathology image-gene FMs, each of which results in distinct functionalities and application scenarios. This review provides an overview of the latest research advancements in pathological FMs, with a particular emphasis on their applications in oncology. The key challenges and opportunities presented by pathological FMs in precision oncology are also explored.

Objective:
This study examined the gut bacterial communities of dogs from different breeds, all kept under identical domestication conditions.
Methods:
Noninvasive sampling and 16S rRNA high-throughput sequencing were used to compare the composition and function of the gut microbiota of three dog breeds: the Chinese Kunming dog (CKD), German Shepherd dog (GSD), and Belgian Malinois dog (BMD).
Results:
The gut microbiota of the three dog breeds consisted of 257 species across 146 genera, 60 families, 35 orders, 15 classes, and 10 phyla. The dominant bacterial phyla across the three breeds were Firmicutes (57.44%), Fusobacteriota (28.86%), and Bacteroidota (7.63%), while the dominant bacterial genera across the three breeds were Peptostreptococcus (21.08%), Fusobacterium (18.50%), Lactobacillus (12.37%), and Cetobacter (10.29%). Further analysis revealed significant differences in the intestinal flora of the three breeds at the phylum and genus levels. The intestinal flora of BMD was significantly richer than that of CKD and GSD. The functional prediction and Kyoto Encyclopedia of Genes and Genomes analysis showed that the primary functions of the gut microbiota in these breeds were similar, with significant enrichment in various metabolic pathways, including carbohydrate and amino acid metabolism, secondary metabolite biosynthesis, and microbial metabolism in different environments. The intestinal flora of these breeds also played a crucial role in genetic information processing, including transcription, translation, replication, and material transport.
Conclusions
and Relevance: These results provide novel insights into the intestinal flora of intervention dogs and suggest novel methods to improve their health status, which help increase microbial diversity and normalize metabolite production in diseased dogs.

During the process of dairy farming,various factors such as physical injury and bacterial infection act upon body tissues or organs,leading to the disruption of skin or mucous tissue integ-rity and subsequent tissue injury and trauma.The healing of these injuries is a complex process that necessitates the coordinated efforts of different cells and involvement of diverse cytokines.A-mong them,the interaction between macrophages and myofibroblasts is indispensable for efficient tissue repair.Nod-like receptor protein 3(NLRP3),a pattern recognition receptor in the innate im-mune system,may play a regulatory role in modulating this intricate process.In this study,cow myofibroblasts and M1 type bone marrow-derived macrophages were cultured in vitro,followed by collection of cell culture supernatant for co-culture analysis.Both cytokine secretion levels in M1 type bone marrow-derived macrophages as well as expression patterns levels of myofibroblast growth factor protein and mRNA were detected.The regulatory mechanism underlying NLRP3 in-volvement in mediating interactions between these two cell types was investigated using NLRP3 inhibitor MCC950.The results showed that an effective method for culturing cow muscle fibroblasts in vitro was successfully established and myofibroblast conditioned medium(MFbCM)could regulate M1 macrophage secretion profiles.Moreover,M1 macrophage conditioned medium(M1?CM)was found to influence myofibroblast growth factor expression levels.Our findings sug-gest that NLRP3 plays a significant regulatory role during crosstalk between myofibroblasts and M1-type pro-inflammatory macrophages.

Objective:To analyze clinical features, short-term efficacy and side effects of salvage re-irradiation therapy for patients with locally recurrent esophageal cancer after definitive chemoradiotherapy, to investigate the prognostic factors of re-irradiation with precise radiotherapy techniques.Methods:A retrospective analysis was performed on patients with locally recurrent esophageal squamous cell carcinoma after definitive chemoradiotherapy treated in the Fourth Hospital of Hebei Medical University from January 2008 to December 2016. The patients underwent re-irradiation therapy (re-RT) or re-irradiation therapy concurrent chemotherapy (re-CCRT). The main observation index was after-recurrence survival (ARS), which was calculated by Kaplan-Meier method for survival analysis. Univariate analysis was conducted by log-rank test, and multivariate analysis was performed by Cox regression model.Results:A total of 109 patients were included, with a median age of 66 years (43-89 years), and a median follow-up time of 120.8 months (79.0-176.5 months). The objective response rates (ORR) and dysphagia improvement rates (DIR) in all patients were 64.2% and 63.0%, respectively. The median ARS and 1-, 3-, 5-, 8-year survival rates in all patients were 7.8 months and 32.1%, 9.2%, 7.3% and 2.3%, respectively. The median ARS and 1-, 3-, 5-years survival rates were 10.8 months and 45.9%, 13.5%, 10.8% for patients with time to recurrence (TTR) ≥24 months, significantly longer than those of 5.7 months and 25.0%, 6.9%, 5.6% for patients with TTR<24 months ( χ2=7.99, P=0.005). The median ARS in groups with re-irradiation dose of ≤50 Gy,>50-54 Gy, and>54 Gy groups were 5.7, 10.0 and 8.1 months, respectively ( χ2=6.94, P=0.031). The 1-, 3- and 5-year survival rates were 30.4%, 5.1%, and 3.8% for re-RT versus 36.7%, 20.0%, and 16.7% for re-CCRT ( χ2=2.12, P=0.145). Multivariate analysis showed that TTR ( HR=0.607, 95% CI=0.372-0.991, P=0.046) and lesion length ( HR=0.603, 95% CI=0.371-0.982, P=0.042) were the independent factors for ARS. There was no significant difference in ≥2 grade pneumonitis and 2-3 grade radiation esophagitis between the re-RT and re-CCRT groups ( χ2=0.25, P=0.619; χ2=0.51, P=0.808). The morbidity of ≥2 grade myelosuppression in the re-RT group was significantly lower than that in the re-CCRT group (3.7% vs. 36.7%, χ2=18.15, P<0.001). Conclusions:Precise re-irradiation therapy for patients with locally recurrent esophageal cancer after definitive chemoradiotherapy can alleviate dysphagia, but ARS remains poor. Re-irradiation dose range from>50-54 Gy may be suitable for locally relapse patients as salvage treatment. Patients with TTR≥24 months and lesion length ≤5 cm obtain favorable prognosis.

Background::While type 2 diabetes mellitus (T2DM) is considered a putative causal risk factor for coronary artery disease (CAD), the intrinsic link underlying T2DM and CAD is not fully understood. We aimed to highlight the importance of integrated care targeting both diseases by investigating the phenotypic and genetic relationships between T2DM and CAD.Methods::We evaluated phenotypic associations using data from the United Kingdom Biobank ( N = 472,050). We investigated genetic relationships by leveraging genomic data conducted in European ancestry for T2DM, with and without adjustment for body mass index (BMI) (T2DM: Ncase/ Ncontrol = 74,124/824,006; T2DM adjusted for BMI [T2DM adjBMI]: Ncase/ Ncontrol = 50,409/523,897) and for CAD ( Ncase/ Ncontrol = 181,522/984,168). We performed additional analyses using genomic data conducted in multiancestry individuals for T2DM ( Ncase/ Ncontrol = 180,834/1,159,055). Results::Observational analysis suggested a bidirectional relationship between T2DM and CAD (T2DM→CAD: hazard ratio [HR] = 2.12, 95% confidence interval [CI]: 2.01–2.24; CAD→T2DM: HR = 1.72, 95% CI: 1.63–1.81). A positive overall genetic correlation between T2DM and CAD was observed ( rg = 0.39, P = 1.43 × 10 -75), which was largely independent of BMI (T2DM adjBMI–CAD: rg = 0.31, P = 1.20 × 10 –36). This was corroborated by six local signals, among which 9p21.3 showed the strongest genetic correlation. Cross-trait meta-analysis replicated 101 previously reported loci and discovered six novel pleiotropic loci. Mendelian randomization analysis supported a bidirectional causal relationship (T2DM→CAD: odds ratio [OR] = 1.13, 95% CI: 1.11-1.16; CAD→T2DM: OR = 1.12, 95% CI: 1.07-1.18), which was confirmed in multiancestry individuals (T2DM→CAD: OR = 1.13, 95% CI: 1.10-1.16; CAD→T2DM: OR = 1.08, 95% CI: 1.04-1.13). This bidirectional relationship was significantly mediated by systolic blood pressure and intake of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, with mediation proportions of 54.1% (95% CI: 24.9-83.4%) and 90.4% (95% CI: 29.3-151.5%), respectively. Conclusion::Our observational and genetic analyses demonstrated an intrinsic bidirectional relationship between T2DM and CAD and clarified the biological mechanisms underlying this relationship.

Objective:
The aim of the study was to investigate the association of outdoor physical activity and insomnia symptoms with depressive symptoms in college students, so as to provide a theoretical basis for preventing and improving depression of the college students.
Methods:
A sample survey of 9 349 college students from 4 colleges and universities in 3 provinces in Hubei, Jiangxi and Chongqing were conducted from November to December 2021. The Patient Health Questionnaire, Insomnia Severity Index and outdoor physical activity questionnaire were used to evaluate the depressive symptoms, insomnia symptoms and outdoor activities of college students, respectively. The χ 2 test was used to compare the difference of the positive rate of depressive symptoms in college students. Logistic regression analysis was used to analyze the association between outdoor physical activity, insomnia symptoms and depressive symptoms. Generalized linear model was used to analyze the association of interaction effect of outdoor activity and insomnia symptoms with depressive symptoms.
Results:
The detection rate of depressive symptoms in college students was 37.4%. Significant differences in the detection rate of depressive symptoms were observed among college students with different majors, nationalities,educational backgrounds, family residence, family type, family economic conditions, study burden, number of friends, father s education level,mother s education level( P <0.05). Logistic regression analysis showed that outdoor physical activity ( OR=0.51-0.69, P <0.01) and insomnia symptoms ( OR=6.15-21.30, P <0.01) were associated with depressive symptoms( P <0.01). Generalized linear model showed that insomnia symptoms( B =0.57), outdoor physical activity ( B =-0.15) and their interaction terms ( B =-0.02) were associated with college students depression( P <0.05).
Conclusion
This study suggests that insufficient time for outdoor physical activity and insomnia symptoms may increase the risk of depressive symptoms in college students. College students with insufficient time for outdoor physical activity and insomnia have a higher risk of developing depressive symptoms.

Objective:To learn about the implementation of prevention and control measures in drinking water-borne endemic fluorosis areas and the trend of the disease change in Jiangsu Province.Methods:In March to October 2021, a general survey was carried out in 1 972 villages with drinking water-borne endemic fluorosis in 27 counties (cities and districts) of Jiangsu Province, the operation of water improvement projects in the villages was monitored, and the water fluoride content was determined. The prevalence of dental fluorosis among children aged 8 to 12 years in all the villages was investigated.Results:The 1 972 villages with drinking water-borne endemic fluorosis had completed water improvement, and all water improvement projects were operating normally and the water was qualified. Among them, 1 774 villages in the disease affected areas had achieved the control goal, accounting for 89.96%; and there were 198 villages in the disease affected areas with control measures up to the standard, accounting for 10.04%. A total of 47 water improvement projects were monitored, including 2 small-scale water improvement projects, accounting for 4.26%. There were 45 large-scale water improvement projects, accounting for 95.74%. A total of 125 790 children aged 8 to 12 years were examined, and 12 625 cases of dental fluorosis were detected. The detection rate of dental fluorosis was 10.04%, and the dental fluorosis index was 0.19. The detection rate of dental fluorosis in children aged 8 to 12 years was 9.98% (1 854/18 579), 10.27% (2 704/26 323), 9.48% (2 765/29 152), 9.73% (2 835/29 145) and 10.92% (2 467/22 591), respectively, with statistically significant difference (χ 2 = 10.51, P = 0.015). Among the 198 villages with control measures up to standard, according to the historical water fluoride, the detection rate of dental fluorosis in children in each water fluoride range (1.20-2.00, 2.01-3.00, 3.01-4.00, > 4.00 mg/L) was 37.73% (698/1 850), 43.17% (1 176/2 724), 45.50% (769/1 690) and 55.20% (802/1 453), respectively, with a statistically significant difference (χ 2 = 104.15, P < 0.001). Conclusion:The water improvement measures in drinking water-borne endemic fluorosis areas in Jiangsu Province have achieved significant results, which still need to be further consolidated.
