Objective: To identify the effective needs of college students for dietary nutrition health education content, so as to provide a scientific basis for optimizing the health education strategies in colleges. Methods: The literature analysis method, focus group interviews and Delphi expert consultation method were used to construct a survey questionnaire on dietary nutrition health education for college students. From January to March 2024, a total of 597 college students from six colleges in Shandong Province were selected through convenience sampling to complete the questionnaire independently by scanning the two dimensional code on questionnaire star. The Kano model was used to define the content demands of college students for dietary nutrition education, and the differences in demands were analyzed by calculating satisfied influence (SI) and dissatisfied influence (DSI). Results: The compiled questionnaire was divided into 7 dimensions and 25 items. The overall demand level analysis of college students included 3 essential attribute demands, namely, the recommended intake and various forms of dairy products (34.17%), the role of whole grains in health with their scientific intake forms and recommended amounts (31.99%), and the intake of beans (30.15%); 7 expected attribute demands included the introduction of recommended intensity of different activities (35.01%), how to achieve a healthy weight and the balance between diet and exercise (41.54%), the energy consumed by different exercises in a unit of time ( 38.36 %), the selection of healthy snacks (36.68%), the types of infectious diseases of the digestive system and how to prevent and control them (25.96%), the causes and judgments with manifestations of nutrition related diseases among college students ( 28.14 %), and the hotspots of attention on nutrition related diseases among college students (24.46%); 4 attractive attribute demands contained the introduction of the recommended activity levels for different periods such as daily and weekly (28.81%), the introduction of the importance of activities and the harm of prolonged sitting and ways to avoid it (28.64%), the nutritional value of animal foods and eating suggestions (23.45%), and the scientific intake suggestions for various processed animal foods (22.11%); the remaining were 11 attribute demands with no differences. In the quadrant diagram analysis, the demand items located in the maintenance zone, competitive advantage zone, improvement zone, and minor improvement zone were 5, 5, 8, and 7, respectively. Conclusions College students have different demands in dietary nutrition health education, and whether these demands are met affects their satisfaction in different ways. Among them, education on the intake of dairy products, whole grains, and beans has the greatest impact on satisfaction.

To address challenges related to privacy protection and regulatory compliance in cross-institutional data collaboration， a "trusted federated evidence-based analysis platform for TCM spleen-stomach diseases" is proposed， integrating blockchain-based smart contracts， federated learning， and secure multi-party computation. The deep integration of AI with privacy-preserving computing is reshaping research and clinical practice in TCM spleen-stomach diseases， providing feasible pathways and a technical framework for building a high-quality， trustworthy TCM big-data ecosystem and achieving precision syndrome differentiation.

Objective To analyze the predictive value of different obesity indicators on acute cerebral infarction in patients with transient ischemic attack (TIA). Methods A total of 310 patients with TIA admitted to Tangdu Hospital of Air Force Medical University from March 2022 to September 2025 were selected and classified into non-event group (276 cases) and cerebral infarction group (34 cases) based on acute cerebral infarction within 90 days. The basic data and obesity-related indicators [body mass index (BMI), waist-to-hip ratio, body adiposity index (BAI), conicity index (C-index) and a body shape index (ABSI were compared. Multivariate logistic regression analysis was utilized to screen the independent influencing factors. Receiver operating characteristic (ROC) curve was drawn to analyze the predictive efficiency. Results The age, proportions of concurrent hypertension and concurrent diabetes mellitus, ABCD2 score, waist-to-hip ratio, ABSI, C-index, BMI and BAI in the cerebral infarction group were older or higher than those in the non-event group, and the symptoms duration was longer (P<0.05). The above indicators were all related factors for acute cerebral infarction in patients with TIA within 90 days (P<0.05), and ABSI and ABCD² score were independent influencing factors (P<0.05). The prediction model was manifested as Logit (P)=− 4.205 + 0.482 × ABCD² score + 1.120 × ABSI × 100. ABSI and ABCD2 score had predictive value on the occurrence of acute cerebral infarction (P<0.05), and the predictive efficiency of combined model was higher than that of single indicator (P<0.05). Conclusion Among different obesity indicators, ABSI has the highest value on predicting recent acute cerebral infarction in TIA. The prediction model based on ABSI and ABCD2 score exhibits the best predictive efficiency.

Objective To investigate the prevalence of common diseases among primary and secondary school students in Yichang City from 2019 to 2022, and to provide a scientific basis for formulating effective intervention measures in the future. Methods By random cluster sampling , 7 schools in urban areas and 5 schools in suburban counties were selected to screen common diseases such as myopia, dental caries, obesity and abnormal spinal curvature. Descriptive epidemiological methods were employed for statistical analysis. Results A total of 17 023 primary and secondary school students were screened from 2019 to 2022. The overall detection rate of common diseases from high to low was myopia (54.12%), caries (36.75%), overweight (15.17%), obesity (11.88%), malnutrition (5.80%), and abnormal spinal curvature (3.49%). The detection rates of myopia and abnormal curvature of the spine showed an increasing trend with years and school stages, while the detection rates of malnutrition and dental caries showed a decreasing trend with years and school stages. The detection rates of overweight and obesity showed no trend difference with years, and the detection rates of obesity showed a decreasing trend with school stages. The rates of myopia, overweight and obesity were higher in urban areas than those in suburban counties, and the rate of dental caries was higher in suburban counties than that in urban areas. The prevalence of overweight, obesity, and malnutrition in boys was higher than that in girls. The prevalence of myopia and dental caries in girls was higher than that in boys. The above differences were statistically significant (all P<0.05). Conclusion Myopia, dental caries, obesity, and abnormal curvature of the spine are the current focus of the prevention and treatment of common diseases in students. There are great differences between different regions, school stages, and genders. The ^“tripartite linkage^” of schools, families, and communities should be achieved with the joint efforts of the education and health departments to actively take targeted intervention measures to reduce the prevalence.

Conclusion: This system achieves full-process management of preoperative anemia through information technology, significantly enhancing the standardization of diagnosis and treatment as well as intervention effectiveness, providing an effective solution for perioperative anemia management.

Objective To investigate the mechanism of DNA methyltransferase 1(DNMT1)inhibitor combined with extracellular signal-regulated kinase 1(ERK1),homeodomain-interacting protein kinase 2(HIPK2),and glycogen synthase kinase 3 β(GSK3 β)inhibitors in synergistically inducing apoptosis and protein arrest in relapsed and refractory acute myeloid leukemia(AML)cells.Methods Three therapeutic targets,including ERK1,HIPK2,and GSK3β,were screened based on the Gene Expression Omnibus(GEO),The Cancer Genome Atlas(TCGA)database,and Ex-pression 2 Kinases database.Human AML cell line U937 cells were treated with DNMT1 inhibitor a-lone or combined with ERK1,HIPK2,or GSK3β inhibitors.Cell viability was detected using the CCK-8 method.Apoptosis rate was analyzed by flow cytometry,and cell cycle distribution was de-termined by propidium iodide(PI)staining.The mRNA expression levels of DNMT1,ERK1,HIPK2,and GSK3β were detected by real-time fluorescent quantitative reverse transcriptionpoly-merase chain reaction(RT-qPCR).Protein expressionlevels of DNMT1,ERK1,HIPK2,and GSK3β were detected by immunoblotting.Results DNMT1 inhibitor significantly inhibited the cell viability of U937 cells,and significantly induced apoptosis and cell cycle arrest in U937 cells(P＜0.05).When DNMT1 inhibitor was combined with ERK1,HIPK2,or GSK3β inhibitors,cell via-bility and apoptosis rate were significantly reduced(P＜0.05).DNMT1 inhibitor alone or its com-bination with ERK1,HIPK2,and GSK3β inhibitors induced U937 cell arrest in the G0/G,phase,with a significant increase in the proportion of cells in the G0/G1 phase in the combination group(P＜0.05).The combination of DNMT1 inhibitor with ERK1,HIPK2,and GSK3β inhibitors sig-nificantly reduced the mRNA expression levels in DNMT1,ERK1,HIPK2,and GSK3β in U937 cells(P＜0.05).Similarly,the combination therapy significantly reduced the protein expression levels of DNMT1,ERK1,HIPK2,and GSK3β in U937 cells(P＜0.05).Conclusion DNMT1 inhibitor combined with ERK1,HIPK2,and GSK3 β inhibitors can synergistically induce apoptosis and protein arrest in relapsed and refractory AML cells,providing a novel strategy for combined tar-geted therapy of AML.

Real-time,noninvasive programmed death-ligand 1(PD-L1)testing using molecular imaging has enhanced our understanding of the immune environments of neoplasms and has served as a guide for immunotherapy.However,the utilization of radiotracers in the imaging of human brain tumors using positron emission tomography/computed tomography(PET/CT)remains limited.This investigation involved the synthesis of[18F]AlF-NOTA-PCP2,which is a novel peptide-based radiolabeled tracer that targets PD-L1,and evaluated its imaging capabilities in orthotopic glioblastoma(GBM)models.Using this tracer,we could noninvasively monitor radiation-induced PD-L1 changes in GBM.[18F]AlF-NOTA-PCP2 exhibited high radiochemical purity(＞95％)and stability up to 4 h after synthesis.It demonstrated specific,high-affinity binding to PD-L1 in vitro and in vivo,with a dissociation constant of 0.24 nM.PET/CT imaging,integrated with contrast-enhanced magnetic resonance imaging,revealed significant accumulation of[18F]AlF-NOTA-PCP2 in orthotopic tumors,correlating with blood-brain barrier disruption.After radiotherapy(15 Gy),[18F]AlF-NOTA-PCP2 uptake in tumors increased from 9.51％±0.73％to 12.04％±1.43％,indicating enhanced PD-L1 expression consistent with immunohisto-chemistry findings.Fractionated radiation(5 Gy × 3)further amplified PD-L1 upregulation(13.9％±1.54％ID/cc)compared with a single dose(11.48％±1.05％ID/cc).Taken together,[18F]AlF-NOTA-PCP2 may be a valuable tool for noninvasively monitoring PD-L1 expression in brain tumors after radiotherapy.

Hyssopus cuspidatus is an authentic medicinal herb used in Xinjiang， rich in the chemical constituents including flavonoids， phenolic acids and terpenoids. It possesses anti-inflammatory， antioxidant， and immunomodulatory effects. Modern pharmacological studies have demonstrated that H. cuspidatus exerts therapeutic effects on asthma by inhibiting airway inflammatory responses， suppressing airway remodeling， modulating the function of the hypothalamic-pituitary-adrenal axis， and relaxing bronchial smooth muscle. It also demonstrates intervention effects on chronic obstructive pulmonary disease by reducing levels of inflammatory cytokines and regulating immune balance. Additionally， H. cuspidatus can mitigate acute lung injury by inhibiting oxidative stress and intervene in lung cancer by suppressing proliferation and promoting apoptosis of lung cancer cells. In terms of clinical application， compound preparations containing H. cuspidatus， such as Hanchuan zupa granules and Luo’ou kezupa， have demonstrated favorable therapeutic effects on pulmonary diseases including asthma， cough， and pediatric bronchopneumonia. Currently， the research on precise action targets and compound matching rules of H. cuspidatus remains inadequate. Future studies should integrate modern technologies such as metabolomics to conduct in-depth exploration， thereby promoting the modernized development and clinical application of this traditional medicinal herb.

Real-time, noninvasive programmed death-ligand 1 (PD-L1) testing using molecular imaging has enhanced our understanding of the immune environments of neoplasms and has served as a guide for immunotherapy. However, the utilization of radiotracers in the imaging of human brain tumors using positron emission tomography/computed tomography (PET/CT) remains limited. This investigation involved the synthesis of [¹⁸F]AlF-NOTA-PCP2, which is a novel peptide-based radiolabeled tracer that targets PD-L1, and evaluated its imaging capabilities in orthotopic glioblastoma (GBM) models. Using this tracer, we could noninvasively monitor radiation-induced PD-L1 changes in GBM. [¹⁸F]AlF-NOTA-PCP2 exhibited high radiochemical purity (>95%) and stability up to 4 h after synthesis. It demonstrated specific, high-affinity binding to PD-L1 in vitro and in vivo, with a dissociation constant of 0.24 nM. PET/CT imaging, integrated with contrast-enhanced magnetic resonance imaging, revealed significant accumulation of [¹⁸F]AlF-NOTA-PCP2 in orthotopic tumors, correlating with blood-brain barrier disruption. After radiotherapy (15 Gy), [¹⁸F]AlF-NOTA-PCP2 uptake in tumors increased from 9.51% ± 0.73% to 12.04% ± 1.43%, indicating enhanced PD-L1 expression consistent with immunohistochemistry findings. Fractionated radiation (5 Gy × 3) further amplified PD-L1 upregulation (13.9% ± 1.54% ID/cc) compared with a single dose (11.48% ± 1.05% ID/cc). Taken together, [¹⁸F]AlF-NOTA-PCP2 may be a valuable tool for noninvasively monitoring PD-L1 expression in brain tumors after radiotherapy.

Geriatric oral health care encounters significant challenges with the increase in the proportion of older individuals. Age-related changes in the dentition, muscles, and joints result in a decline in objective masticatory function, subjective restoration requirements, and acceptability among the elderly population, with individual variations influenced by systemic health. Considering functional requirements, the adaptability of stomatognathic and systemic health conditions, health economics and other factors, the authors believe that it should not be limited to the conventional "one-to-one" strategy for replacing missing teeth in geriatric prosthodontics. There is an urgent need for a precise and adaptable restoration strategy that is more suitable for older individuals. The proposal of a new concept of functional tooth loss updates the minimal restoration standards for elderly patients and establishes the theory of age-friendly functional restoration. Based on the restoration strategy of functional tooth loss, this paper proposes a new concept termed "age-friendly functional restoration of the stomatognathic system", which integrates treatment considerations including endodontics, periodontology, mucosa, muscles, temporomandibular joint, and systemic health. Efforts should be made in four areas as follows. Firstly, the "assessment of accessible function" should be enhanced by considering the interrelationship between stomatognathic and systemic health. Secondly, the "evaluation of appropriate function" is supposed to be optimised in view of subjective needs and objective evaluation of the stomatognathic system. Moreover, the "formulation of treatment plans" needs to be accomplished with the aid of assistive technologies, such as artificial intelligence, to accurately exert appropriate functional restoration. Lastly, the "management and maintenance of health" is likely to be strengthened through follow-ups, propaganda and education, and preventive healthcare, so as to improve quality of life and ultimately achieve healthy ageing among older individuals.
