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.

Autoimmune hepatitis （AIH） is a chronic inflammatory liver disease mediated by T lymphocytes， and it can progress to liver cirrhosis or even liver failure without timely intervention. As a natural flavonoid compound， naringenin （NAR） shows a potential value in the prevention and treatment of AIH through multiple mechanisms such as remodeling immune homeostasis， targeted inhibition of inflammatory pathways， antioxidation， regulating hepatocyte metabolism and apoptosis， improving mitochondrial function， and regulating intestinal flora. However， the clinical translation and application of NAR is limited by issues such as low bioavailability and insufficient efficiency of liver-targeted delivery. This article systematically reviews the mechanism of action of NAR in the prevention and treatment of AIH， explores the potential signaling pathways involved in this process， and analyzes existing challenges in its translation and application and future research directions， so as to provide a reference for further research on NAR and its application in the prevention and treatment of AIH.

Cholangiocarcinoma (CCA) is a malignancy characterized by tumor cells originating in the liver or bile ducts, exhibiting features of cholangiocyte differentiation. It poses a significant clinical challenge due to the limited diagnostic and therapeutic options available. Robust animal models are essential for advancing our understanding of CCA pathogenesis and developing effective treatments. This review provides a comprehensive overview of CCA mouse models, highlighting various approaches, including chemical induction, genetically engineered models, and tumor xenografts. Each model is discussed in terms of its establishment techniques, pathological characteristics, and research significance, with a focus on intrahepatic CCA. Chemical induction models, such as diethylnitrosamine- and azoxymethane-induced models, offer insights into tumorigenesis processes, whereas genetically modified models involving alterations in key genes such as Kirsten rat sarcoma viral oncogene homolog, tumor protein 53, and isocitrate dehydrogenase serve as important tools for studying the molecular mechanisms underlying CCA. Xenograft models, including patient-derived xenografts, bridge the gap between experimental research and clinical applications, allowing for precise therapeutic evaluations. By comparing these models, this review underscores their respective advantages and limitations, paving the way for future studies aiming to optimize and innovate CCA modeling strategies.

Objective:To evaluate the effect of acupuncture on postoperative delirium (POD) in diabetic patients undergoing surgery under general anesthesia.Methods:In this randomized controlled trial, 92 diabetic patients of either sex, aged 30-80 yr, with a body mass index of 18-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective surgery under general anesthesia, were divided into 2 groups ( n=46 each) using a table of random numbers: control group (group C) and acupuncture group (group A). Group A received acupuncture at the Baihui (GV20), Shenting (GV24) and Sishencong (EX-HN1) acupoints before anesthesia. The needles were retained for 30 min, with manual stimulation applied every 10 min for 10 s each time. After 4 stimulations, routine anesthesia was carried out. Group C received routine anesthesia only. Regional cerebral oxygen saturation was recorded on admission to the operating room (T 0), after anesthesia induction (T 1), at the start of surgery (T 2), at the end of surgery (T 3), and immediately after tracheal extubation (T 4). The POD developed within 3 days after surgery was assessed. The occurrence of needle-related adverse effects such as fainting, subcutaneous bleeding, and local paresthesia was recorded. Results:Compared with group C, the incidence of POD was significantly reduced, and the regional cerebral oxygen saturation was increased at T 1, 4 in group A ( P<0.05). Conclusions:Acupuncture can decrease the development of POD in diabetic patients undergoing surgery under general anesthesia, which is related to an increase in regional cerebral oxygen saturation.

Objective To develop a graded early mobility implementation pathway for critically ill adult patients in tertiary hospitals in Beijing and to preliminarily validate its feasibility and effectiveness.Methods Based on the"goal-directed"early mobility concept,a graded early mobility implementation pathway for critically ill patients was developed through evidence synthesis and the Delphi method,consisting of 3 components:patient inclusion,mobility implementation,and mobility evaluation.Using convenience sampling,patients meeting inclusion criteria in the general ICU of a tertiary hospital in Beijing from October 2024 to January 2025 were selected as participants.Among them,25 patients admitted from December 2024 to January 2025 were assigned to an experimental group and received early mobility interventions following the developed pathway.25 patients admitted from October to November 2024 served as a control group and received routine ICU mobility care.Outcomes including diaphragm excursion,muscle strength,ICU length of stay,and adverse events were compared between the 2 groups.Results The graded early mobility pathway achieved an implementation rate of 70.05％in the experimental group,significantly higher than it in the control group(P＜0.001),without increasing adverse events.Post-intervention diaphragm excursion in the experimental group was significantly greater than that in the control group(P=0.018).Conclusion The developed graded early mobility implementation pathway for ICU patients demonstrates scientific rigor and clinical practicality.It provides a reference for the widespread and effective implementation of early mobility in ICUs,standardizing its clinical application.

Objective:To explore the impulsivity characteristics of patients with attention deficit hyperactivity disorder(ADHD)comorbid with borderline personality disorder(BPD)and the mediating role of emotion regula-tion strategies.Methods:A total of 96 patients with ADHD meeting the diagnostic criteria of the American Diagnos-tic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-Ⅳ)were enrolled,48 of whom had comorbid BPD.Impulsivity was assessed with the Barratt Impulse Scale(BIS)and the impulse control difficulty dimensions of Emotional Regulation Difficulty Scale(DERS).Emotion regulation strategies were evaluated with the Emotion Regulation Questionnaire(ERQ).Results:No significant differences were found between the ADHD with and with-out BPD group in cognitive impulsivity,motor impulsivity,or non-planning impulsivity as assessed with the BIS(Ps＞0.05).However,the ADHD with BPD group showed higher scores on the DERS impulse control difficulty subscale(P＜0.001)and less frequent use of cognitive reappraisal strategies(P＜0.001).Cognitive reappraisal partially mediated the relationship between ADHD with BPD and impulse control difficulties,with an effect size of 25.9％.Conclusion:ADHD patients comorbid with BPD exhibit heightened emotional impulsivity,which might be partially mediated by reduced use of cognitive reappraisal.

Objective:To investigate the impact of hysteroscopic surgery on fresh embryo transfer outcomes in patients with transvaginal ultrasound-diagnosed FIGO Type Ⅱ/Ⅲ uterine fibroids that may affect the uterine cavity morphology, providing a reference for clinical practice.Methods:A retrospective cohort study was performed to analyze the clinical data of 346 patients who visited the Reproductive Medicine Center, Department of Obstetrics and Gynecology, Peking University Third Hospital between January 2020 and December 2022, with transvaginal ultrasound findings indicating uterine fibroids adjacent to or protruding into the uterine cavity (FIGO Type Ⅱ, Ⅲ) and who underwent fresh embryo transfer. Patients were divided into two groups based on whether hysteroscopic surgery were performed: the hysteroscopic surgery group ( n=237, the group that underwent hysteroscopy before embryo transfer) and the non-surgery group ( n=109, the group that proceeded directly to embryo transfer without hysteroscopy). Basic patient characteristics and pregnancy outcomes were compared between the two groups. Multivariate logistic regression analysis was used to identify factors influencing clinical pregnancy rate and live birth rate. Results:The baseline characteristics showed no statistically significant differences between the two groups. The clinical pregnancy rate [44.3% (105/237)] and the live birth rate [32.5% (77/237)] following fresh embryo transfer in the hysteroscopic surgery group were significantly higher than those in the non-surgery group [31.2% (34/109), P=0.021; 18.3% (20/109), P=0.007], whereas the pregnancy loss rate showed no significant difference. Stratified analysis by age revealed that for patients aged <35 years, the clinical pregnancy rate [62.1% (54/87)] and the live birth rate [51.7% (45/87)] in fresh embryo transfer cycles were significantly higher in the hysteroscopic surgery group compared with the non-surgery group [30.8% (12/39), P=0.001; 25.6% (10/39), P=0.006]. Multivariate logistic regression analysis further confirmed that hysteroscopic surgery was an independent factor influencing live birth rate ( OR=2.128, 95% CI: 1.152-3.930, P=0.016). Among patients aged <35 years, hysteroscopic surgery was an influencing factor of both clinical pregnancy rate ( OR=4.222, 95% CI: 1.745-10.215, P=0.001) and live birth rate ( OR=3.449, 95% CI: 1.436-8.282, P=0.006). Conclusion:For infertile patients with ultrasound findings of uterine fibroids adjacent to or protruding into the uterine cavity, especially younger patients, hysteroscopy is recommended. It can improve pregnancy outcomes of fresh embryo transfer, increasing both the clinical pregnancy rate and the live birth rate.

Objective:To observe the clinical effect of the new type of lung body projection flashlight for percussion back in patients with cerebral hemorrhage, so as to promote patient lung rehabilitation, reduce pulmonary complications, and improve prognosis.Methods:Adopting a randomized controlled trial method, a total of 102 patients with cerebral hemorrhage who were hospitalized in the Department of Neurosurgery of The First Hospital of Jiaxing from January 2022 to December 2023 and their caregivers were selected as the research objects by convenience sampling method. The patients were divided into the control group (51 cases) and the observation group (51 cases) by the random number table method. The control group received traditional back tapping on the basis of routine nursing and back tapping guidance. The observation group used a new type of lung body projection flashlight for percussion back to assist in back tapping nursing and health guidance on the basis of routine nursing.The incidence of pulmonary infection, white blood cell count, levels of hypersensitive C-reactive protein and procalcitonin, the quality of discharge guidance, the scores of satisfaction of patients, and the assessment score of caregivers′ percussion back skills were evaluated in the two groups.Results:Finally, a total of 49 patients were enrolled in the observation group, including 38 males and 11 females, aged (67.08 ± 11.05) years old. A total of 49 patients were enrolled in the control group, including 31 males and 18 females, aged (68.84 ± 10.46) years old. There were 8 males and 41 females, aged (58.00 ± 8.17) years old in the caregivers of the observation group. There were 6 males and 43 females, aged (57.57 ± 9.15) years old in the caregivers of the observation group. The incidence of pulmonary infection in the observation group was 28.6% (14/49), which was lower than that in the control group 32.7% (16/49), and the difference was not statistically significant ( P>0.05). There was no significant difference in the level of white blood cell count, hypersensitive C-reactive protein and procalcitonin between the two groups when the time of pulmonary infection was diagnosed and after 2 weeks of treatment ( P>0.05). The levels of white blood cell count, hypersensitive C-reactive protein and procalcitonin after 1 week of treatment were (7.97 ± 1.30)×10 9/L, (30.71 ± 11.96) mg/L, 0.04(0.02, 0.07) μg/L in the observation group, which were all lower than those in the control group (9.46 ± 2.16) × 10 9/L, (58.34 ± 48.96) mg/L, 0.09(0.04, 0.20) μg/L, and the differences were statistically significant ( t=5.06, 4.22, Z=1.98, all P<0.05). The total score of discharge guidance quality, obtained content, guidance skills and effect scores were (134.94 ± 7.34), (47.80 ± 2.86), (87.14 ± 5.98) points in the observation group, which were significantly higher than those in the control group (117.04 ± 7.04), (39.80 ± 3.15), (77.24 ± 5.60) points, and the differences were statistically significant ( t=12.32, 13.15, 8.46, all P<0.05). The scores of the satisfaction of patients including six aspects(operation convenience, precise positioning, goal orientation, operation specification, nursing confidence and mission satisfaction) in the observation group were 91.84%(45/49), 95.92%(47/49), 91.84%(45/49), 93.88%(46/49), 91.84%(45/49), 97.96%(48/49), which were higher than those in the control group 73.47%(36/49), 57.14%(28/49), 53.06%(26/49), 67.35%(33/49), 73.47%(36/49), 81.63%(40/49), and the differences were statistically significant ( χ2 values were 5.76-20.51, all P<0.05). The assessment score of percussion skills of caregivers in the observation group was (79.55 ± 3.98) points, which was significantly higher than that in the control group (75.35 ± 4.94) points, and the difference was statistically significant ( t=4.64, P<0.05). Conclusions:The clinical application of the new type of lung body projection flashlight for percussion back in patients with cerebral hemorrhage can achieve accurate and standardized percussion back to promote the improvement of pulmonary infection and improve the skill level of caregivers of cerebral hemorrhage patients, as well as improve the quality of discharge guidance and the satisfaction of patients.
