ObjectiveTo address the challenges of unstructured classical Chinese expressions, nested entity relationships, and limited annotated data in famous traditional Chinese medicine(TCM) case records, this study proposes a joint relation extraction framework that integrates data augmentation and entity mapping, aiming to support the construction of TCM diagnostic knowledge graphs and clinical pattern mining. MethodsWe developed an annotation structure for entities and their relationships in TCM case texts and applied a data augmentation strategy by incorporating multiple ancient texts to expand the relation extraction dataset. A cascade binary tagging framework for relation triple extraction(CasRel) model for TCM semantics was designed, integrating a pre-trained bidirectional encoder representations from transformers(BERT) layer for classical TCM texts to enhance semantic representation, and using a head entity-relation-tail entity mapping mechanism to address entity nesting and relation overlapping issues. ResultsExperimental results showed that the CasRel model, combining data augmentation and entity mapping, outperformed the pipeline-based Bert-Radical-Lexicon(BRL)-bidirectional long short-term memory(BiLSTM)-Attention model. The overall precision, recall, and F1-score across 12 relation types reached 65.73%, 64.03%, and 64.87%, which represent improvements of 14.26%, 7.98%, and 11.21% compared to the BRL-BiLSTM-Attention model, respectively. Notably, the F1-score for tongue syndrome relations increased by 22.68%(69.32%), and the prescription-syndrome relations performed the best with the F1-score of 70.10%. ConclusionThe proposed framework significantly improves the semantic representation and complex dependencies in TCM texts, offering a reusable technical framework for structured mining of TCM case records. The constructed knowledge graph can support clinical syndrome differentiation, prescription optimization, and drug compatibility, providing a methodological reference for TCM artificial intelligence research.

ObjectiveTo develop a community-family management model for older adults with mild cognitive impairment (MCI) and to formulate detailed application specifications, and to fully leverage the initiative of communities and families under limited resource conditions, for achieving community-based early detection and early intervention for older adults with MCI. MethodsA systematic literature review was conducted to identify pertinent publications. Corpus-based research methodologies were employed to extract, refine, integrate and synthesize management elements, thereby establishing the specific content and service processes for each stage of the management model. Utilizing the 5W2H analytical framework, essential elements such as management stakeholders, target populations, content and methods for each stage were delineated. The model and its application guidelines were finalized through expert consultation and demonstration. ResultsAn expert evaluation of the management model yielded mean scores of 4.84, 4.32 and 4.84 for acceptability, feasibility and systematicity, respectively. By integrating the identified core elements with expert ratings and feedback, the final iteration of the community-family management model for older adults with MCI was formulated. This model comprised of five stages: screening and identification, comprehensive assessment, intervention planning, monitoring and referral pathways to ensure implementation, and enhanced support for communities, family members and caregivers. Additionally, it included 18 specific application guidelines. ConclusionThe proposed management model may theoretically help delay cognitive decline, improve cognitive function and potentially promote reversal from MCI to normal cognition. It may also enhance the awareness and coping capacity of older adults and their families, strengthen community healthcare professionals' ability to early identify and manage MCI.

Objective:
To study the correlation between short sleep duration and screening myopia among primary and middle school students in Beijing, so as to provide a scientific basis for the comprehensive prevention and control of myopia among students.
Methods:
Using a stratified cluster random sampling, 25 593 primary and middle school students from 16 districts of Beijing were selected from September to November 2023. The National Common Diseases and Health Influencing Factors Monitoring Survey Questionnaire was used to conduct a questionnaire survey, and visual acuity was tested according to the Specification for the Screening of Refractive Error in Primary and Middle School Students. The reporting rates of short sleep duration and detection rates of screening myopia among primary and middle school students were compared using the Chi square test. Binary Logistic regression was used to analyze the correlation between short sleep duration and screening myopia.
Results:
About 68.63% of students reported short sleep duration. There was a statistically significant difference in the reporting rate of short sleep duration among students in different school stages ( χ 2=981.18, P <0.01), with the lowest reporting rate of vocational high school students (47.07%) and the highest reporting rate of ordinary high school students (76.17%). The detection rates of screening myopia among primary school students ( 57.09% ) and middle school students (76.53%) who reported short sleep duration were higher than those who reported enough sleep duration (52.65%, 71.94%), with satistically significant differences ( χ 2=14.83, 17.96, P <0.01). The results of binary Logistic regression analysis showed that primary and middle school students with short sleep duration had a higher risk of developing screening myopia, compared to students with enough sleep duration ( OR =1.25); after adjusting for confounding factors such as educational stage, gender, region, boarding situation, primary and secondary school students with short sleep duration still had a higher risk of screening myopia ( OR =1.26) ( P <0.01). The analysis results stratified by educational stage showed that primary school students from grades 4-6 and middle school students with short sleep duration had a higher risk of screening myopia ( OR=1.18, 1.20, P <0.01).
Conclusions
Primary and secondary school students in Beijing with short sleep duration sleep have a higher risk of developing screening myopia. Families, schools, and society should ensure enough sleep duration to reduce the occurrence of myopia among students.

ObjectiveTo investigate the analgesic effect of Tuina at the "Weizhong (BL 40)" on neuropathic pain in a rat model of chronic constriction injury (CCI) of the sciatic nerve and its potential central spinal mechanisms. MethodsThirty-two Sprague-Dawley rats were randomly divided into four groups (8 rats in each group), sham-operated group, model group, Tuina group, and blockade group. The CCI model was established in the model group, Tuina group, and the blockade group by ligating the sciatic nerve with catgut, while the sham-operated group underwent only sciatic nerve exposure without ligation. From postoperative day 4 to day 14, rats in the Tuina group and the blockade group received Tuina manipulation at the "Weizhong (BL 40)" using a dynamic pressure distribution measurement system (5 N pressure, 2 Hz frequency, 10 min per session, once daily). The blockade group also received intraperitoneal injections of the microglial inhibitor minocycline (10 mg/kg) once daily. The sham-operated and the model group underwent the same handling and fixation as the Tuina group without actual Tuina. Mechanical withdrawal threshold (MWT) and paw withdrawal latency (PWL) were measured before surgery and on day 3, 7, 10, and 14 post-surgery. Transmission electron microscopy was used to evaluate sciatic nerve injury and repair, measuring axon diameter and total myelinated fiber diameter to calculate the g-ratio. Western Blotting was performed to detect the protein levels of ionized calcium-binding adapter molecule 1 (Iba-1), CD206, CD68, interleukin-10 (IL-10), and β-endorphin (β-EP) precursor pro-opiomelanocortin (POMC) in the ipsilateral spinal dorsal horn. ResultsCompared with the sham-operated group, the model group showed significantly reduced MWT and PWL on day 3, 7, 10, and 14 (P<0.01). Compared with the model group, the Tuina group and the blockade group showed increased MWT and PWL on day 10 and 14 (P<0.05). Compared with the Tuina group, the blockade group exhibited higher MWT on day 7, 10, and 14, and higher PWL on day 10 (P<0.05). Sciatic nerve pathological morphology revealed intact and well-structured myelin in the sham-operated group, while the model group exhibited myelin collapse, distortion, and myelin ovoid formation. The Tuina group displayed partially irregular myelin with occasional myelin collapse, whereas the blockade group exhibited partial myelin irregularities and phospholipid shedding. Compared with the sham-operated group, the model group showed a decreased g-ratio and increased levels of Iba-1 and CD68 in the spinal dorsal horn (P<0.05 or P<0.01). Compared with the model group, the Tuina group and the blockade group exhibited an increased g-ratio and reduced Iba-1 and CD68 levels. Additionally, the Tuina group showed elevated levels of CD206, IL-10, and POMC, whereas the blockade group had decreased CD206 levels (P<0.05). ConclusionTuina at "Weizhong (BL 40)" alleviates neuropathic pain in CCI rats, potentially by regulating microglial activation in the spinal cord, inhibiting M1 polarization while promoting M2 polarization, and activating the IL-10/β-EP pathway to exert analgesic effects.

ObjectiveTo explore the clinical safety of Feilike Mixture (FLK) in the real world. MethodsThe safety of all children who received FLK from 29 institutions in 12 provinces between January 21,2021 and December 25,2021 was evaluated through prospective centralized surveillance and a nested case control study. ResultsA total of 3 035 juveniles were included. There were 29 research centers involved,which are distributed across 12 provinces,including one traditional Chinese medicine (TCM) hospital and 28 general hospitals. The average age among the juveniles was (4.77±3.56) years old,and the average weight was (21.81±12.97) kg. Among them,119 cases (3.92%) of juveniles had a history of allergies. Acute bronchitis was the main diagnosis for juveniles,with 1 656 cases (54.46%). FLK was first used in 2 016 cases (66.43%),and 142 juvenile patients had special dosages,accounting for 4.68%. Among them,92 adverse drug reactions (ADRs) occurred,including 73 cases of gastrointestinal system disorders,10 cases of metabolic and nutritional disorders,eight cases of skin and subcutaneous tissue diseases,two cases of vascular and lymphatic disorders,and one case of systemic diseases and various reactions at the administration site. The manifestations of ADRs were mainly diarrhea,stool discoloration,and vomiting,and no serious ADRs occurred. The results of multi-factor analysis indicated that special dosages (the use of FLK)[odds ratio (OR) of 2.642, 95% confidence interval (CI) of 1.105-6.323],combined administration: spleen aminopeptide (OR of 4.978, 95%CI of 1.200-20.655),and reason for combined administration: anti-infection (OR of 1.814, 95%CI of 1.071-3.075) were the risk factors for ADRs caused by FLK. Conclusion92 ADRs occurred among 3 035 juveniles using FLK. The incidence of ADRs caused by FLK was 3.03%,and the severity was mainly mild or moderate. Generally,the prognosis was favorable after symptomatic treatment such as drug withdrawal or dosage reduction,suggesting that FLK has good clinical safety.

ObjectiveTo explore the potential mechanism of action of the combination of Sanguisorbae Radix-Sophorae Flos (DH) in the treatment of ulcerative colitis (UC) using network pharmacology methods and molecular docking technology. MethodsNetwork pharmacology analysis was utilized to predict the potential targets of DH for the treatment of UC. The therapeutic effects were experimentally validated by inducing a UC model in mice with 3% dextran sulfate sodium (DSS). The experimental groups were the normal group, the model group, the salazosulfapyridine group (100 mg·kg-1), and the low, medium, and high dose groups of DH (1.2, 2.4, and 4.8 g·kg-1). The efficacy of the treatment was assessed through the general condition of the mice, histopathological examination, and the expression levels of inflammatory markers in the colon. The effect of DH on angiogenesis was explored by messenger RNA (mRNA) detection of colonic angiogenesis-related mediators, vascular endothelial growth factor (VEGF) immunohistochemistry, microvessel density (MVD) detection, and transmission electron microscopy. The phosphatidylinositol-3-kinase (PI3K)-protein kinase B (Akt) signaling pathway proteins were quantitatively analyzed through Western blot to assess whether the suppression of pathological angiogenesis by DH is associated with this pathway. ResultsNetwork pharmacological analysis yielded 112 potential core therapeutic targets for the treatment of UC with DH, of which the core targets were tumor protein 53 (TP53), JUN, interleukin (IL)-6, Akt1, and tumor necrosis factor (TNF). Compared with the normal group, mice in the model group showed significant weight loss, colon shortening, and high DAI score, increased expression of inflammatory factors IL-6, IL-1β, and TNF-α, as well as increased mRNA expression levels of angiogenesis-related mediators VEGF, vascular cell adhesion molecule 1 (VCAM1), angiotensin 1 (Ang1), matrix metalloproteinase (MMP)-1, MMP-2, and MMP-9. The positive expression of CD31 and VEGF in colonic tissue increased, and the protein expression of the PI3K/Akt pathway was increased (P<0.05). The endothelial cells of the colonic mucosa and the colonic vasculature were severely damaged. Compared with the model group, mice in the DH groups had significantly reduced weight loss and colon shortening, lower DAI scores, and a significant decrease in mRNA expression of inflammatory factors and angiogenesis-related mediators. In addition, there was decreased positive expression of CD31 and VEGF in colonic tissue and decreased protein expression of the PI3K/Akt pathway (P<0.05). ConclusionNetwork pharmacology, molecular docking, and experimental validation are applied to explore the mechanism of action of DH in the treatment of UC, and it is found that DH is able to improve the symptoms of colitis and inhibit the pathological angiogenesis in UC mice. Its action might be related to affecting the PI3K/Akt pathway.

ObjectiveTo preliminarily explore the active components and target pathways of Angelicae Sinensis Radix-Polygonati Rhizoma (ASR-PR) herb pair in the treatment of simple obesity through network pharmacology and molecular docking, and to verify and investigate its mechanism of action via animal experiments. MethodsThe chemical constituents and targets of ASR and PR were predicted using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP). Targets related to simple obesity were identified by retrieving the GeneCards, Online Mendelian Inheritance in Man (OMIM), Pharmacogenomics Knowledgebase (PharmGKB), and DisGeNET databases. The intersection of drug and disease targets was used to construct an active component-target network using Cytoscape software. This network was imported into the STRING database to construct a protein-protein interaction (PPI) network, and topological analysis was conducted to identify core genes. Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis and mapping were performed using the DAVID database and the Microbioinformatics platform. AutoDock 1.5.7 software was used to perform molecular docking between the top five active components and core targets. An animal model of simple obesity was established by feeding C57BL/6J mice a high-fat diet. The mice were administered ASR (2.06 g·kg-1), PR (2.06 g·kg-1), or ASR-PR (4.11 g·kg-1) for 10 weeks, while the model group received an equal volume of purified water by gavage. After the administration period, the mice were sacrificed to measure body fat weight and serum levels of total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), and low-density lipoprotein (LDL). Hematoxylin-eosin (HE) staining was used to observe histopathological sections of liver and adipose tissue. Serum levels of leptin, interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were determined by enzyme-linked immunosorbent assay (ELISA), and the mRNA expression levels of epidermal growth factor receptor (EGFR) and signal transducer and activator of transcription 3 (STAT3) in liver tissue were detected by real-time quantitative polymerase chain reaction (Real-time PCR). ResultsNetwork pharmacology and molecular docking results indicated that the treatment of simple obesity by ASR-PR may involve the regulation of protein expression of core targets EGFR and STAT3 by its main components MOL009760 (Siberian glycoside A_qt), MOL003889 (methyl protodioscin_qt), MOL009766 (resveratrol), MOL006331 (4′,5-dihydroxyflavone), and MOL004941 (baicalin), thereby modulating the PI3K/Akt and JAK/STAT signaling pathways. The animal experiment results showed that compared with the normal group, the model group had significantly increased body weight, body fat weight, and serum levels of TG, TC, TNF-α, IL-6, and leptin (P<0.01). EGFR mRNA expression was significantly elevated (P<0.05), while STAT3 mRNA expression was significantly decreased (P<0.01). Histological analysis revealed disordered hepatic architecture in the model group, with pronounced lipid vacuoles, cytoplasmic loosening, lipid accumulation, and steatosis. Adipocytes in white adipose tissue (WAT) and brown adipose tissue (BAT) of the model group exhibited markedly increased diameters, reduced cell counts per unit area, and irregular morphology. Compared with the model group, the ASR-PR group significantly reduced body weight, body fat weight, serum TC, IL-6, TNF-α, leptin levels, and EGFR mRNA expression (P<0.01). TG levels were also significantly decreased (P<0.05), while STAT3 mRNA expression was significantly increased (P<0.01). Histopathological improvements included reduced size and number of hepatic lipid vacuoles and restoration of liver cell morphology toward that of the normal group. The diameter of adipocytes significantly decreased, and the number of adipocytes per unit area increased. ConclusionASR-PR may regulate the expression of key target proteins such as EGFR and STAT3 via its core active components, modulate the PI3K/Akt and JAK/STAT signaling pathways, repair damaged liver and adipose tissues, and thereby alleviate the progression of obesity in mice.
