Natural flavonoids have attracted considerable attention owing to their favorable biosafety profiles and multiple pharmacological properties in recent years. Luteolin, a representative flavonoid compound, exhibits anti-inflammatory, antioxidant, anti-angiogenic, and neuroprotective effects in multiple ocular disease models by modulating key signaling pathways, including NF-κB, PI3K/Akt, Nrf2/HO-1, and AGE-RAGE. Accumulating experimental evidence supports the potential application of luteolin in various ocular diseases, including corneal and ocular surface diseases, inflammatory eye diseases, glaucoma, cataract, diabetic retinopathy, and age-related macular degeneration. However, clinical evidence remains limited. This review systematically summarizes research progress on luteolin in ocular diseases over the past five years, analyzes its molecular mechanisms and therapeutic potential, and discusses future directions,so as toprovide a theoretical basis for clinical translation.

This paper outlines the development of artificial intelligence （AI） and its applications in traditional Chinese medicine （TCM） research， and elucidates the roles and advantages of large language models， knowledge graphs， and natural language processing in advancing syndrome identification， prescription generation， and mechanism exploration. Using spleen-stomach diseases as an example， it demonstrates the empowering effects of AI in classical literature mining， precise clinical syndrome differentiation， efficacy and safety prediction， and intelligent education， highlighting an upgraded research paradigm that evolves from data-driven and knowledge-driven approaches to intelligence-driven models. 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.

The incidence rate of suspected adverse events following immunization (AEFI) after single administration of pentavalent recombinant rotavirus attenuated live vaccine (RV5) in Chaoyang District, Beijing City from 2019 to 2021 was 362.3 per 100 000 doses. The incidence rate of AEFI after simultaneous administration with oral polio vaccine (OPV), inactivated polio vaccine (IPV), hepatitis B vaccine (HBV), Haemophilus influenzae type b (Hib), and pneumococcal conjugate vaccine 13-valent (PCV13) was 239.3 per 100 000, 643.4 per 100 000, 346.8 per 100 000, 438.1 per 100 000, and 434.0 per 100 000, respectively. The specific incidence rates for common AEFI symptoms such as fever, local allergic rash, irritability, and vomiting under different vaccination regimens were as follows: RV5 alone (fever: 88.3 per 100 000, rash: 9.1 per 100 000, irritability: 100.5 per 100 000, vomiting: 83.3 per 100 000), RV5 and IPV simultaneous administration (fever: 239.4 per 100 000, rash: 104.7 per 100 000, irritability: 134.7 per 100 000, vomiting: 89.8 per 100 000), RV5 and OPV simultaneous administration (fever: 119.6 per 100 000, rash: 32.6 per 100 000, irritability: 32.6 per 100 000, vomiting: 32.6 per 100 000), RV5 and HBV simultaneous administration (fever: 111.0 per 100 000, rash: 69.4 per 100 000, irritability: 83.2 per 100 000, vomiting: 41.6 per 100 000), RV5 and Hib simultaneous administration (fever: 159.3 per 100 000, rash: 238.9 per 100 000, irritability: 0 per 100 000, vomiting: 39.8 per 100 000), and RV5 and PCV13 simultaneous administration (fever: 142.8 per 100 000, rash: 98.0 per 100 000, irritability: 126.0 per 100 000, vomiting: 25.2 per 100 000).

Objective:To analyze risk factors associated with false-positive results of quantitative fecal immunochemical testing (FIT), evaluate its performance for detecting advanced colorectal neoplasia across different subgroups, and explore the optimal positivity thresholds for each subgroup.Methods:Individuals who participated in the Zhejiang Colorectal Cancer Screening Program in 2020-2021, completed questionnaire-based risk assessment and quantitative FIT for initial screening, and undertook colonoscopy for confirmed diagnosis were included in this study. The information of individuals, including demographic characteristics, lifestyles, history of diseases, and family history of colorectal cancer (CRC), was collected by using questionnaires. The diagnostic outcomes of the individuals were obtained through colonoscopy and pathological examination. Multivariate logistic regression analyses were conducted to identify factors associated with false-positive FIT results. The optimal threshold of FIT was determined based on the receiver operating characteristic (ROC) curve and 10-fold cross-validation. The effectiveness of FIT screening in different subgroups was compared using the unified threshold of 100 ng/ml or optimal positivity thresholds.Results:There were 25 874 individuals included in the analysis, with 14 694 (56.79%) having fecal hemoglobin concentrations ≥100 ng/ml. A total of 3 830 advanced adenoma cases (14.80%) and 362 CRC cases (1.40%) were identified. Age below 60 years old, females, underweight, smoking, drinking, use of nonsteroidal anti-inflammatory drugs, no family history of CRC, no history of intestinal disease, no history of hypertension, and physical inactivity were associated with an elevated risk of false-positive results in FIT ( P<0.05). Compared to the predetermined threshold of 100 ng/ml, the false positive rate (FPR) of quantitative FIT decreased from 52.3% to 37.3% in all individuals, and decreased by more than 20% in females, individuals with normal weight, smokers, and those without a history of intestinal disease when adopting the optimal threshold (all P<0.001). Conclusion:The risk of false-positive results in quantitative FIT varies across different subgroups. Adopting the optimal thresholds could improve the specificity and reduce the FPR of quantitative FIT for CRC screening.

Objective To investigate the impact of anticentromere antibody(ACA)on the clinical features and prognosis of patients with primary biliary cholangitis(PBC)by comparing clinical classification,ursodeoxycholic acid(UDCA)response,GLOBE score,and UK-PBC score between ACA-positive PBC patients and ACA-negative PBC patients.Methods A total of 749 patients who were admitted to Beijing Ditan Hospital,Capital Medical University,from August 2013 to December 2022 and were diagnosed with PBC were enrolled and divided into ACA-positive group with 147 patients and ACA-negative group with 602 patients.According to their conditions on admission,the two groups were compared in terms of the distribution of clinical types,i.e.,chronic progression-type PBC,portal hypertension-type PBC,and standard jaundice/liver failure-type PBC.There were 261 patients with complete data after 1-year follow-up,among whom there were 53 patients with positive ACA and 208 with negative ACA.A statistical analysis was performed,and propensity score matching was performed based on sex and age at a ratio of 1∶2.The two groups were compared in terms of 1-year UDCA response rate,GLOBE score,and UK-PBC score before and after matching.The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups,and the chi-square test was used for comparison of categorical data between two groups.Results Compared with the ACA-negative group,the ACA-positive group had a significantly higher age(61.28±10.35 years vs 56.74±12.17 years,t=4.164,P<0.001),a significantly higher proportion of female patients(93.9%vs 77.6%,χ2=20.221,P<0.001),a significantly higher proportion of patients with portal hypertension(48.3%vs 27.6%,χ2=23.289,P<0.001),and a significantly lower proportion of patients with jaundice/liver failure(24.5%vs 38.5%,χ2=10.205,P<0.001).After 1-year follow-up,for the 261 PBC patients with complete data,there was no significant difference in UDCA response rate before propensity score matching between the ACA-positive group and the ACA-negative group(41.5%vs 41.8%,P>0.05),and there was a significant difference in the proportion of patients with a GLOBE score of>0.3 between the ACA-positive group and the ACA-negative group(92.5%vs 80.3%,χ2=3.935,P=0.047).There were 53 patients in the ACA-positive group and 106 patients in the ACA-negative group after propensity score matching,and there were no significant differences between the two groups in UDCA response rate,GLOBE score,and UK-PBC score(all P>0.05).Conclusion ACA-positive patients tend to have an older age,with a higher proportion of female patients or patients with portal hypertension,while there is a relatively low proportion of patients with jaundice/liver failure.Positive ACA has no significant impact on UDCA response rate,GLOBE score,and UK-PBC score.

OBJECTIVE: To explore the clinical, genetic, therapeutic and prognostic characteristics of two children with Lesch-Nyhan syndrome (LNS) in order to enhance understanding of this disease and formulate more effective therapeutic strategies. METHODS: Clinical data were collected from two children clinically diagnosed with LNS who were treated at Anhui Provincial Children's Hospital from April 2023 to January 2024. Data were retrospectively collected and included clinical manifestations (symptoms, signs, laboratory and imaging findings), treatment course, and results of follow-up. Peripheral venous blood samples were obtained from child 1 and his parents. Whole-exome sequencing (WES) was performed. Candidate variants were validated by Sanger sequencing. Standard bioinformatic analysis of the raw WES data was conducted, including quality control, alignment, variant calling, and annotation. Candidate pathogenic variants were filtered using population frequency databases (e.g., gnomAD), disease databases (e.g., OMIM, ClinVar), and multiple in silico pathogenicity prediction tools (e.g., SIFT, PolyPhen-2, CADD). Phenotype matching was integrated using Human Phenotype Ontology (HPO) terms. Pathogenicity classification of variants was performed according to the American College of Medical Genetics and Genomics (ACMG) Standards and Guidelines for the Interpretation of Sequence Variants (2015). This study was approved by the Medical Ethics Committee of Anhui Children's Hospital, Children's Hospital of Fudan University (Ethics No.: EYLL-2014-027). RESULTS: Child 1, a 4-year-old boy, had presented with developmental delay for over 3 years, accompanied by abnormal postures and involuntary lip-biting. Physical examination revealed limb dystonia, anxious expression, lower lip damage, and communication difficulties. Laboratory tests showed hyperuricemia and renal stones. Genetic testing identified a hemizygote variant of the HPRT1 gene, c.135G>T (p.Arg45Ser), inherited from an asymptomatic carrier mother, which confirmed the diagnosis of LNS. This variant was absent from population databases (gnomAD, 1000 Genomes, dbSNP). Protein function prediction tools consistently indicated it as a pathogenic or likely pathogenic variant (SIFT, PolyPhen-2, CADD, and REVEL scores all reached pathogenic thresholds). Protein structural modeling revealed that the variant may disrupt the hydrogen-bonding network compromising the tetramer stability. ACMG classification designated it as likely pathogenic (PM1+PM2_Supporting+PM5+PP3). The patient was treated with benhaxol hydrochloride, baclofen, and clonazepam to improve his neurological symptoms, in addition with treatment with febuxostat from the Nephrology Department to manage his purine metabolism. After one year of follow-up, the patient's abnormal posture showed slight improvement, self-injurious behavior persisted but was managed with protective gloves, blood uric acid levels normalized, and renal stones decreased. Case 2, a 13-year-old boy, was hospitalized to the Nephrology Department due to urinary tract infection. Following successful control of the infection, his limb dystonia has worsened, leading to his transfer to the Neurology Ward. The patient had a history of delayed motor and language development, abnormal postures, and lip-biting self-injurious behavior, with elevated blood uric acid levels, leading to the diagnosis of LNS. His parents had declined genetic testing due to financial constraints. Following discharge, the patient did not adhere to the prescribed medication regimen or attend scheduled outpatient visits. The patient had died by the time of the 4-month follow-up contact. CONCLUSION Variants of the HPRT1 gene probably underlay the LNS in the two children, and the HPRT1 is the only known pathogenic gene for LNS. Early genetic diagnosis, strict adherence to multidisciplinary comprehensive treatment, and intensive intervention for self-injurious behaviors are crucial for improving the quality of life and prolonging the survival of children with LNS.

Objective: To develop and validate a health literacy assessment scale for junior high school students, providing an effective tool for evaluating and monitoring health literacy among Chinese adolescents. Methods: Based on school health education policy documents, a health literacy assessment framework was constructed, comprising five horizontal and four vertical dimensions. From May to June and August to September in 2024, the framework was refined through Delphi expert consultations and focus group discussions, leading to the development of the Health Literacy Assessment Scale for Junior High School Students. In September 2024, a convenience sample of 625 students from three junior high schools in Beijing and Tianjin completed the questionnaire. Item analysis, reliability, and validity tests were conducted to evaluate the scale. Results: The recovery rate for two rounds of expert consultation questionnaires was 100%. The expert authority coefficients ( Cr ) were 0.86 and 0.87 respectively (both >0.70), with Kendall W values of 0.34 and 0.27 ( P <0.05). The focus group discussions followed a rigorous structure, and after multiple rounds of item screening and revision, the version 3.0 of the junior high school students health literacy assessment scale was developed, comprising 57 items. Three items that failed to meet the comprehensive screening criteria were preliminarily removed, and the final scale contained 54 items. The scale demonstrated excellent reliability, with an overall Cronbach s α coefficient of 0.92 and split half reliability of 0.93. Confirmatory factor analysis [ χ 2/df =2.094, root mean square error of approximation ( RMSEA )=0.042, comparative fit index ( CFI )=0.911, Tucker Lewis index ( TLI )=0.907] indicated good model fit indices. Conclusions The preliminary development of the health literacy assessment scale for junior high school students follows a rigorous item screening process with well designed dimensions, demonstrating good reliability and validity, thus serving as an appropriate evaluation tool for adolescent health literacy.

Aquatic organisms can secrete biomacromolecules through specialized organs, tissues, or structures, enabling adhesion to underwater material surfaces and leading to severe biofouling issues. This phenomenon adversely impacts aquatic ecosystem health and human activities. Biofouling has emerged as an emerging global environmental challenge. Adhesion serves as the foundation of biofouling, representing a critical step toward a comprehensive understanding of the adhesion mechanisms of aquatic organisms. Biomacromolecules, including proteins, lipids, and carbohydrates, are the primary functional components in the adhesive substances of aquatic fouling organisms. Research indicates that these biomacromolecules exhibit diversity in types and characteristics across different aquatic organisms, yet their adhesion mechanisms show unifying features. Despite significant progress, there remains a lack of comprehensive reviews on the adhesion mechanisms mediated by biomacromolecules in aquatic fouling organisms, particularly on the roles of lipids and carbohydrates. Through a comprehensive analysis of existing literature, this review systematically summarizes the mechanistic roles of three classes of macromolecules in aquatic biofouling adhesion processes. Proteins demonstrate central functionality in interfacial adhesion and cohesion through specialized functional amino acids, conserved structural domains, and post-translational modifications. Lipids enhance structural stability via hydrophobic barrier formation and antioxidative protection mechanisms. Carbohydrates contribute to adhesion persistence through cohesive reinforcement and enzymatic resistance of adhesive matrices. Building upon these mechanisms, this review proposes four prospective research directions: optimization of protein-mediated adhesion functionality, elucidation of lipid participation in adhesion dynamics, systematic characterization of carbohydrate adhesion modalities, and investigation of macromolecular synergy in composite adhesive systems. The synthesized knowledge provides critical insights into underwater adhesion mechanisms of aquatic fouling organisms and establishes a theoretical foundation for developing mechanism-driven antifouling strategies. This work advances fundamental understanding of bioadhesion phenomena while offering practical guidance for next-generation antifouling technology development.
