Objective: To examine the reciprocal relationships of anxiety and depressive symptoms,uncertainty stress with academic buoyancy among college students, providing evidence for mental health promotion and academic resilience enhancement. Methods: A multi stage cluster random sampling method was used to selected 741 undergraduates from grade 1 to 2 of a university in Xuzhou, Jiangsu Province. Participants completed two waves of surveys (T1: October 2022; T2: October 2023) using the Uncertainty Stress Scale, Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), and Academic Buoyancy Scale. Cross lagged models analyzed bidirectional relationships between three mental health variables and academic buoyancy, followed by latent variable modeling integrating all mental health dimensions. Results: Cross lagged model results revealed that T1 uncertainty stress negatively predicted T2 academic buoyancy ( β =-0.14), while T1 academic buoyancy negatively predicted T2 uncertainty stress ( β =-0.11); T1 depressive symptom negatively predicted T2 academic buoyancy ( β =-0.08), while T1 academic buoyancy negatively predicted T2 depressive symptom ( β =-0.09); furthermore, T1 academic buoyancy negatively predicted T2 anxiety symptom( β =-0.10) ( P <0.05). Results from the latent variable cross lagged model of psychological problems (constructed from the three mental health variables) indicated that T1 psychological problems negatively predicted T2 academic buoyancy ( β =-0.09), while T1 academic buoyancy negatively predicted T2 psychological problems ( β =-0.09) ( P <0.05). Conclusions Longitudinal bidirectional relationships exist between mental health status and academic buoyancy in college students. Better mental health facilitates higher academic buoyancy.

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.

The repair of the periodontal membrane is essential for the successful management of periodontal disease and dental trauma. Emdogain^® (EMD) is widely used in periodontal therapy due to its ability to promote repair. Despite substantial research, the cellular and molecular mechanisms underlying EMD's effects, particularly at the single-cell resolution, remain incompletely understood. This study established a delayed tooth replantation model in rats to investigate these aspects. Tooth loss rate and degree of loosening were evaluated at 4 and 8 weeks. Micro-CT, HE staining, TRAP staining, and immunofluorescence staining were evaluated to assess EMD's efficacy. Single-cell sequencing analyses generated single-cell maps that explored enrichment pathways, cell communication, and potential repair mechanisms. Findings indicated that EMD could reduce the rate of tooth loss, promote periodontal membrane repair, and reduce root and bone resorption. Single-cell analysis revealed that EMD promotes the importance of Vtn+ fibroblasts, enhancing matrix and tissue regeneration functions. Additionally, EMD stimulated osteogenic pathways, reduced osteoclastic activity, and promoted angiogenesis-related pathways, particularly bone-related H-type vessel expression in endothelial cells. Gene modules associated with angiogenesis, osteogenesis, and odontoblast differentiation were identified, suggesting EMD might facilitate osteogenesis and odontoblast differentiation by upregulating endothelium-related genes. Immune cell analysis indicated that EMD did not elicit a significant immune response. Cell communication analysis suggested that EMD fostered pro-regenerative networks driven by interactions between mesenchymal stem cells, fibroblasts, and endothelial cells. In conclusion, EMD proves to be an effective root surface therapy agent that supports the restoration of delayed replantation teeth.

Immune checkpoint inhibitors (ICIs) have been approved for the treatment of urothelial carcinoma(UC). However, the use of antibiotics, proton pump inhibitors, corticosteroids, beta-blockers, metformin, and statin concomitant medications in some patients due to complications during the treatment process may affect the clinical efficacy of ICIs through different pathway, making it difficult for patients to derive clinical benefit or making it more likely to develop drug resistance. In this paper, we present a review of the effects of the above concomitant drugs on ICIs in the treatment of patients with advanced UC, with a view to provide reference for the application of individualized treatment strategies of ICIs in patients with advanced UC.

Objective To evaluate the impact of ultra-high-molecular-weight polyethylene(UHMWPE)-Ribbond fi-bers,when combined with different restorative materials,on fracture resistance and marginal adaptation of isolated pri-mary molar defects,to provide a reference for clinical practice.Methods This study was approved by the Ethics Re-view Committee.A total of 72 extracted primary molars with complete crowns were collected,and 66 primary molars were randomly assigned as experimental groups for the fracture resistance and microleakage tests.The molars were di-vided into six groups(n=11)based on the type of restorative materials and the application of Ribbond fibers:Group A1,3M Filtek Z250+Ribbond;Group A2,3M Filtek Z250;Group B1,Beautifil Ⅱ LS+Ribbond;Group B2,Beautifil Ⅱ LS;Group C1,3M Filtek Bulk Fill+Ribbond;and Group C2,3M Filtek Bulk Fill.Groups A1,B1 and C1 received the fiber-reinforcing technique,whereas Groups A2,B2 and C2 received the direct restorative technique;the remainings were in Group D(blank control group),which did not receive treatment for the fracture resistance test.The fracture re-sistance test was divided into six experimental groups and one blank control group(n=6).Primary molar teeth in each experimental group were prepared with Class Ⅱ cavities and filled.The fracture load of all samples was detected,and the fracture mode was analyzed after thermal cycling.The microleakage test was divided into six experimental groups,with five in each group.Class Ⅰ cavities with a diameter of 3 mm and depth of 2.5 mm were prepared within the mesial and distal marginal ridges on the occlusal surface and filled for primary molars in each group.Marginal microleakage was assessed after thermal cycling.Results The fracture resistance test results showed that the fracture resistance in groups that received the fiber-reinforcing technique was greater than that in groups that received the direct restorative technique:Group A1>Group A2,Group B1>Group B2,Group C1>Group C2(P<0.05).The application of Ribbond fibers increased fracture resistance to all tested restorative materials by 37.08％to 39.34％.The proportion of tooth frac-ture decreased significantly in groups A1,C1 compared with A2,C2,with a significant increase in the occurrence rate of"Repairable"(P<0.05).The fracture resistance in Group A1 was significantly greater than that in Group B1 and Group C1(P<0.05).The marginal microleakage test results showed that the microleakage depth in groups that received the fiber-reinforcing technique was smaller than that in groups that received the direct restorative technique:Group A1
