Objective: To investigate the association between emotional intelligence and sleep problems at the symptom level among junior and senior high school students, so as to provide new insights for interventions targeting junior and senior high school students sleep disorders. Methods: From November 2023 to May 2024, a stratified cluster random sampling method was employed to select 3 531 first year junior high school and first year senior high school students from 6 schools in Guangyuan City and Liangshan Yi Autonomous Prefecture in Sichuan Province, as well as Lhasa City in Tibet Autonomous Region. The Insomnia Severity Index Scale and the Wong and Law Emotional Intelligence Scale(WLEIS) were used to assess sleep problems and emotional intelligence. A network analysis was performed to explore the relationship between emotional intelligence and sleep disorders, and a gender based network comparison analysis was conducted. Results: The reported rate of sleep problems among junior and senior high school students was 47.3%, with severe sleep problems of 2.2%. Difficulty maintaining sleep, worry about sleep, and emotional application were the core symptoms in the network (node strength values: 1.11, 0.98, and 0.82, respectively). Dissatisfaction with sleep and emotional application served as bridge symptoms connecting emotional intelligence and sleep problems (bridge strength values: 1.77 and 1.59, respectively). The edge weights of the emotional intelligence and sleep problems network differed significantly between genders (maximum difference in edge weight values was 0.13， P <0.05). Conclusions Emotional application ability and dissatisfaction with sleep are the key nodes in the network connecting emotional intelligence and sleep problems. Targeted efforts to enhance emotional application ability may effectively reduce the risk of sleep problems among junior and senior high school students.

Periodontal disease is a risk factor for many systemic diseases such as Alzheimer's disease and adverse pregnancy outcomes. Cleft palate (CP), the most common congenital craniofacial defect, has a multifaceted etiology influenced by complex genetic and environmental risk factors such as maternal bacterial or virus infection. A prior case-control study revealed a surprisingly strong association between maternal periodontal disease and CP in offspring. However, the precise relationship remains unclear. In this study, the relationship between maternal oral pathogen and CP in offspring was studied by sonicated P. gingivalis injected intravenously and orally into pregnant mice. We investigated an obvious increasing CP (12.5%) in sonicated P. gingivalis group which had inhibited osteogenesis in mesenchyme and blocked efferocytosis in epithelium. Then glycolysis and H4K12 lactylation (H4K12la) were detected to elevate in both mouse embryonic palatal mesenchyme (MEPM) cells and macrophages under P. gingivalis exposure which further promoted the transcription of metallopeptidase domain17 (ADAM17), subsequently mediated the shedding of transforming growth factor-beta receptor 1 (TGFBR1) in MEPM cells and mer tyrosine kinase (MerTK) in macrophages and resulted in the suppression of efferocytosis and osteogenesis in palate, eventually caused abnormalities in palate fusion and ossification. The abnormal efferocytosis also led to a predominance of M1 macrophages, which indirectly inhibited palatal osteogenesis via extracellular vesicles. Furthermore, pharmacological ADAM17 inhibition could ameliorate the abnormality of P. gingivalis-induced abnormal palate development. Therefore, our study extends the knowledge of how maternal oral pathogen affects fetal palate development and provides a novel perspective to understand the pathogenesis of CP.

Antibody (Ab) humanization is critical to reduce immunogenicity and enhance efficacy in the preclinical phase of the development of therapeutic Abs originated from animal models. Computational suggestions have long been desired, but available tools focused on immunogenicity calculation of whole Ab sequences and sequence segments, missing the individual residue sites. This study introduces Site-specific Immunogenicity for Therapeutic Antibody (SITA), a novel computational framework that predicts B-cell immunogenicity score for not only the overall antibody, but also individual residues, based on a comprehensive set of amino acid descriptors characterizing physicochemical and spatial features for antibody structures. A transfer-learning-inspired framework was purposely adopted to overcome the scarcity of Ab-Ab structural complexes. On an independent testing dataset derived from 13 Ab-Ab structural complexes, SITA successfully predicted the epitope sites for Ab-Ab structures with a receiver operating characteristic (ROC)-area unver the ROC curve (AUC) of 0.85 and a precision-recall (PR)-AUC of 0.305 at the residue level. Furthermore, the SITA score can significantly distinguish immunogenicity levels of whole human Abs, therapeutic Abs and non-human-derived Abs. More importantly, analysis of an additional 25 therapeutic Abs revealed that over 70% of them were detected with decreased immunogenicity after modification compared to their parent variants. Among these, nearly 66% Abs successfully identified actual modification sites from the top five sites with the highest SITA scores, suggesting the ability of SITA scores for guide the humanization of antibody. Overall, these findings highlight the potential of SITA in optimizing immunogenicity assessments during the process of therapeutic antibody design.

Objective:To analyze the impact of DRG payment method reform on hospitalization costs and structure in traditional Chinese medicine hospitals.Methods:Using the cost data of hospitalized patients from 2017 to 2022 for public traditional Chinese medicine hospitals in Qingyang and Tianshui,descriptive statistics and two groups interrupted time-series models were implemented to compare the changes before and after DRG payment method reform.Results:DRG payment method reform had no effective impact on the secondary traditional Chinese medicine hospital's average hospitalization costs,average Chinese medicine costs,and average western medicine costs(P＞0.05),but the average proportion of western medicine costs showed an obvious downward trend after the reform(β9=-0.19,P＜0.01).DRG payment method reform resulted in tertiary traditional Chinese medicine hospitals turning to obvious decreasing trends in average hospitalization costs,average Chinese medicine costs,and average western medicine costs(P＜0.05),while the pre-reform decreasing trends in the average proportion Chinese medicine costs share of both secondary and tertiary traditional Chinese medicine hospitals were curbed in the post-reform period.Conclusion:DRG payment method reform had effectively controlled hospitalization costs,Chinese medicine costs,and western medicine costs of tertiary traditional Chinese medicine hospitals,while the cost control of secondary traditional Chinese medicine hospitals has been ineffective,probably contributing to the enhancement of the use of Chinese medicine and the average proportion of Chinese medicine costs.DRG payment method reform for Chinese medicine should strengthen the supervision of costs,actively utilize the advantages of the characteristics of Chinese medicine,and promote the differentiated reform of traditional Chinese medicine hospitals.

Objective:Constructing and exploring the spatial association mechanism of the efficiency of Urban and Rural Residents' Basic Medical Insurance(URRBMI)across provincial regions is of great significance for promoting regional insurance development and constructing a unified national healthcare system.Methods:Using the super-efficiency SBM model and the modified gravity model to build a spatial association network of URRBMI fund operational efficiency from 2020 to 2022.The network structure and driving(actors are analyzed using social network analysis.Results:The spatial association network of URRBMI efficiency exhibits a highly interconnected structure characterized by bilateral reciprocity,triadic closure,and stability,with the network in 2022 being the most compact and showing decreasing internal disparities.It is organized into four major blocks led by the"Beijing-Shanghai-Jiangsu"Region.The spatial association mechanism is driven by three core factors:"geographical proximity,insurance fund pressure,coordination of medical and financial resources".Conclusion:It is suggested to further leverage the role of key provinces,optimize the allocation of medical and financial resources,and enhance the efficiency of insurance management.

Objective:It aims to examine the effects of the employee medical insurance outpatient mutual assistance on medical insurance costs for patients with diabetes mellitus,offering insights for optimizing outpatient insurance policies and chronic disease management strategies.Methods:Outpatient cost settlement data of urban employees with diabetes mellitus in Lanzhou from 2022 to 2023 was collected.Univariate analysis and interrupted time-series models were used to compare relevant medical insurance cost indicators before and after the reform.Results:The inpatient data of 765 730 diabetes mellitus patients were included in the study,and male patients account for 62.67％.After the reform,average per-visit pooling fund expenditure,average per-visit individual payment expenditures,average per-visit personal account expenditure,average per-visit eligible expense amount,average per-visit total fund payment,and the average per-visit proportion of basic medical pooling payments were decreased(P＜0.05).Moreover,average per-visit pooling fund expenditure,average per-visit individual account expenditure,average per-visit cash payment,average per-visit eligible expense amount,average per-visit total fund payment,and the average per-visit proportion of basic medical pooling payments showed a notable declining trend post-reform(P＜0.05).In contrast,the per-visit fully out-of-pocket expenditure exhibited no significant change before and after the reform(P＞0.05).Conclusion:The reform of the employee medical insurance outpatient mutual assistance system has alleviated the economic burden of disease for diabetic patients and improved the efficiency of medical insurance fund utilization,but it reduced the proportion of basic medical pooling payments.It is recommended to continuously refine the outpatient medical insurance payment system,strengthen supervision of medical expenses and service quality,and balance patient benefits with fund pressure to enhance chronic disease outpatient benefits.

Objective To investigate the biomechanical characteristics of the mandibular anterior teeth intrusion assisted by buccal mini-implants,so as to provide theoretical guidance for the clinical treatment of deep overbite and other conditions requiring intrusion of the mandibular anterior teeth.Methods A finite element model of implant screws,clear aligners(CAs)and mandibular complex including the mandibular dentition,periodontal ligament(PDL)and alveolar bone was constructed.The model was designed with 0.2 mm intrusion in the mandibular anterior teeth.Seven groups were set:without traction,30 g,50 g,100 g,150 g,200 g,and 250 g force groups.The stress and displacement of the teeth as well as the related stress distributions of PDL and CAs in each group after loading were analyzed.Results Without traction and under different traction forces,the mandibular anterior teeth tended to be tipped and intruded.With the increase of traction force,the increasing trend was manifested in the vertical displacement and labial displacement of the mandibular anterior teeth.When the traction force reached 200 g,the vertical displacement showed a significant increase,the subsequent increase then showed a tendency to flatten.The ratio of the labial tipping displacement to the intrusive displacement of the mandibular anterior teeth showed a decreasing trend with the increase of traction force.Within a reasonable force range,increasing traction force led to greater bodily intrusion of the anterior teeth.When the traction force was less than 150 g,the mandibular posterior teeth exhibited a tendency of extrusion.When the traction force of more than 150 g was applied,it showed a tendency of intrusion.The PDL stress was concentrated on the labial and cervical surface of the anterior teeth.Conclusions Intrusion efficiency of the mandibular anterior teeth has been effectively improved with CAs assisted by buccal mini-implants.Moreover,the traction force of the mini-implants has a significant impact on the movement of the mandibular anterior teeth.Based on a comprehensive analysis of factors such as the displacement trend of the mandibular dentition and the PDL stress,the optimal force value for buccal traction of the mini-implants to intrude the mandibular anterior teeth can be selected as 150-200 g force.
