ObjectiveTo investigate the mechanism by which Notoginsenoside R1 （NGR1） ameliorates hypoxia/reoxygenation （H/R）-induced injury in AC16 human cardiomyocyte cell lines through the regulation of mitophagy. MethodsCommon genes linked to hypoxia/reoxygenation injury and mitophagy were identified by intersecting data from GeneCards and MitoCarta databases. AC16 cell viability was assessed via CCK-8 assay under varying NGR1 concentrations （0， 6.25， 12.5， 25， 50， 100， 200， 300， 400， 500 μmol/L）. AC16 cells were divided into the following groups： control group （Control）， model group （H/R）， and treatment groups （H/R + NGR1 at 100， 200 and 300 μmol/L）. Mitochondrial membrane potential （ΔΨm） was measured using 5，5'，6，6'-tetrachloro-1，1'，3，3'-tetraethylbenzimidazolylcarbocyanine iodide （JC-1） staining. Transcriptional levels of mitophagy-related genes （Parkin， Pink1， P62） were quantified by reverse transcription-quantitative PCR （RT-qPCR）. Protein expression of mitophagy-related markers （Parkin， Pink1， P62， and LC3BⅡ） was evaluated via Western blot analysis. Mitochondrial ultrastructure was visualized by transmission electron microscopy （TEM）. ResultsCompared to the control group， cell viability in the H/R group significantly decreased （P<0.01）. Treatment with NGR1 at concentrations above 100 μmol/L significantly enhanced the cell viability of AC16 cells compared to the H/R group （P<0.01）. H/R induced a significant decrease in mitochondrial membrane potential （P<0.01）， which was restored by NGR1 treatment （P<0.01）. The mRNA levels of Parkin， Pink1， and P62 in the H/R group were upregulated compared to the control group （P<0.05）， while NGR1 intervention downregulated their expression （P<0.05）. Protein expression levels of Parkin， Pink1， and LC3BⅡ in the H/R group significantly increased， while P62 expression decreased compared to the control group （P<0.01）. In contrast， different doses of NGR1 treatment significantly reduced the expression of Parkin， Pink1， and LC3BⅡ while increasing P62 expression （P<0.05）. TEM revealed that the mitochondrial structure in the H/R group was severely disrupted， with fragmented and disorganized cristae， which was alleviated by NGR1. ConclusionNGR1 ameliorates H/R-induced AC16 cell injury， and its mechanism may be associated with modulating the Pink1/Parkin pathway to suppress excessive mitophagy.

The digitization of traditional Chinese medicine (TCM) has generated vast amounts of data. However, these data are characterized by significant heterogeneity and complex semantic structures, posing substantial challenges for systematic integration and intelligent analysis, and limiting its potential for modern clinical and computational research. To address the challenges posed by the high heterogeneity and complex structure in TCM data, we designed and developed the TCM Data Hub platform, which is powered by the YiYuan large language models (LLMs). This platform aims to enhance intelligent data processing capabilities and unlock the potential for clinical application of TCM data through systematic integration and efficient utilization, thereby bridging the gap between traditional knowledge and modern computational research. This study first analyzed the heterogeneity and complexity of TCM information with respect to data types, structures, and semantics. A standardized data framework was constructed to enhance data integration and interoperability. Based on the TCM Intelligent Computing Platform of the China Academy of Chinese Medical Sciences, we trained the YiYuan LLMs to acquire domain-specific semantic understanding of TCM, thereby improving the platform’s comprehension of specialized terminology and knowledge systems. Leveraging the natural language processing capabilities of the LLMs, we developed a human-in-the-loop data processing system to enable efficient extraction, cleansing, and structured organization of TCM data. In addition, utilizing Vue and Java technologies, we developed multiple LLM-powered intelligent agents and systems, including a human-in-the-loop data processing system, as well as automated prescription mining and network pharmacology analysis agents. Task-specific agents tailored to TCM data processing were developed to enhance the model’s effectiveness in clinical knowledge discovery. System functionality and platform infrastructure were implemented using Java and Vue technologies.The TCM Data Hub platform has completed system construction and core functionality implementation. It supported integrated management and efficient access to 8 key types of TCM data: prescriptions, materia medica, ingredients, targets, diseases (Western medicine), diseases (TCM), syndromes, and therapeutic methods. The human-in-the-loop data processing system achieved an accuracy of 95.34% in structuring TCM data and supported annotation for data requiring manual labeling. The intelligent agent-driven big-data analytics module enabled 1-click, end-to-end workflows for TCM prescription mining, herb-syndrome association analysis, network pharmacology, and molecular biology research, completing a full data mining task in approximately 30 minutes. Users can interact with and manipulate data through a visual front-end interface. The system demonstrated stable performance, strong scalability, and a user-friendly experience. Empowered by the YiYuan LLMs, the TCM Data Hub platform significantly improves the accessibility, usability, and intelligence of TCM data. It effectively bridges traditional TCM knowledge with modern intelligent technologies, providing robust data support and intelligent tools for TCM research and clinical applications.

(4) Combined medication: 5 and 21 kinds of Chinese patent medicines were marked as "highly toxic" and "toxic" in the labels, respectively, 11 kinds of Chinese patent medicines contained incompatible ingredients of "Shibafan" (eighteen antagonisms) and "Shijiuwei (nineteen incompatibilities), and a new review scale for repeated use of Chinese patent medicine was developed.Conclusions:Based on the existing evidence-based medicine, the evidence system of prescription review of Chinese patent medicine is established, the prescription review standards of Chinese patent medicine prescription based on the pharmaceutical interaction mode is formulated and constructed.

Objective:To apply the best evidence-based exercise intervention program for elderly patients with mild cognitive impairment (MCI) to clinical practice and evaluate its effectiveness.Methods:Based on the summary of previous evidence, a best evidence-based exercise intervention program for elderly MCI patients was constructed. Convenience sampling was used to select 86 elderly patients admitted to the Department of Geriatrics of Beijing Hospital and 21 medical and nursing staff participating in the implementation of the program as research subjects. The patients admitted from October 2022 to January 2023 were set as control group, and the patients admitted from May to August 2023 were set as intervention group, with 43 cases in each group. Control group was treated with usual exercise intervention, while intervention group received the best evidence-based exercise intervention program for elderly MCI patients. Knowledge scores of medical and nursing staff and the activities of daily living, grip strength, and cognitive function of two groups of elderly MCI patients were compared before and after the implementation of the program.Results:After the implementation of the program, the scores of the Knowledge Questionnaire for medical and nursing staff were higher than before implementation, and the difference was statistically significant ( P<0.05). The scores of daily living activities and Montreal Cognitive Assessment of elderly MCI patients in intervention group were higher than those in control group, and the differences were statistically significant ( P<0.05). However, there was no statistically significant difference in grip strength between the two groups ( P>0.05) . Conclusions:Applying the best evidence-based exercise intervention program for elderly MCI patients in clinical practice can raise the management level of exercise intervention for elderly MCI patients by clinical medical and nursing staff and improve patient clinical outcomes.

American ginseng (Panax quinquefolius L.), a widely used herbal medicine and dietary supplement, has attracted increasing attention from both academia and industry in recent years. To better understand the research frontiers and hotspots, we conducted a bibliometric analysis of American ginseng studies indexed in the Web of Science Core Collection from 1985 to 2024, using CiteSpace and VOSviewer. A total of 1169 publications were identified, with a marked increase in output since 2011. Hotspot analysis revealed growing interest in pharmacological effects, ginsenoside analysis, polysaccharide studies, and quality control. Furthermore, we assessed future research trends, suggesting that quality control and the modulation of gut microbiota will remain central topics. This study provides a clearer understanding of the evolving research landscape on American ginseng and offers guidance for future investigations.

Objective:To investigate the association between hearing loss and the type of indoor fuel applications in Chinese middle-aged and elderly people through longitudinal cohort study.Methods:Data were obtained from the China Health and Retirement Longitudinal Study (CHARLS), including adults aged 45 years and older enrolled in 2011, with follow-up for cooking and heating analyses extending to 2018 and 2015, respectively. The study calculated the incidence of hearing loss based on an indoor cooking or heating fuel type and expressed in terms of per 100 person-years. The Cox proportional hazard model was used to assess the association between solid fuel use and hearing loss, and covariates such as gender, education, and economy were controlled. We also analyzed the impact of indoor fuel type and its switching on hearing loss.Results:A total of 6, 772 participants using household fuels for cooking (2011-2018) and 4, 618 for heating (2011-2015) were included. Those using solid fuels for cooking [(58.0±8.2) years] and heating [(58.1±8.5) years] were generally slightly older than that of those who used clean fuels. In the cooking analysis, the overall incidence of hearing loss was higher among solid fuel users compared to clean fuel users (Clean fuel: 2.6 cases per 100 person-years; solid fuel: 3.6 cases per 100 person-years; the difference between the two was statistically significant, P<0.05). However, no significant difference was observed in the heating analysis ( P>0.05). Further classification of fuel-type use revealed that the incidence of hearing loss was the highest among people who had been using solid fuels consistently. Compared to the clean fuel group, the fully adjusted hazard ratio (HR) was 1.5 (95% CI: 1.3-1.7) in the cooking analysis and 1.5 (95% CI: 1.1-2.0) in the heating analysis. Compared with using clean fuels, switching from clean fuels to solid fuels increased the risk of hearing loss both during cooking and heating processes. Conclusion:In the CHARLS database, individuals who use solid fuels for indoor cooking and heating are older than those who use clean fuels. Compared with clean fuel use, the use of solid fuels increases the risk of hearing loss in middle-aged and elderly people. Reducing the use of solid fuels, choosing clean fuels as substitutes for solid fuels, and avoiding the switch from clean fuels to solid fuels will help protect the hearing health of middle-aged and elderly individuals.

Objective To explore the molecular mechanisms of moxibustion in improving osteoporosis in rats using high-throughput micro-RNA(miRNA)sequencing analysis.Methods A total of 18 female Sprague-Dawley(SD)rats were randomly divided into an operation group(12 rats),which was subjected to ovariectomy to induce osteoporosis,and a sham operation control(SO)group(6 rats).The 12 osteoporosis model rats were randomly divided into a model(OVX)group and a moxibustion(MOX)group(6 rats per group),which were treated with once-daily moxibustion at the"Shenshu"(BL23)and"Guanyuan"(CV4)acupoints for 20 minutes each time,for 12 weeks.Micro-computed tomography(CT)scans of the rat femur were taken to analyze the trabecular bone thickness(Tb.Th),trabecular separation(Tb.Sp),and bone volume total volume(BV/TV)ratio of the trabecular bone.Hematoxylin and eosin staining was used for morphological observation of tibial tissues.Serum alkaline phosphatase(ALP)and osteocalcin(OCN)levels were measured using ELISA.Three randomly selected rats from each group were used for miRNA high-throughput sequencing to screen for differentially expressed miRNAs,which were subjected to functional enrichment analysis and target gene prediction.Results Micro-CT images showed that,compared with the OVX group,the MOX group had superior bone density,significant increases in the Tb.Th and BV/TV score,and a significant decrease in Tb.Sp(P＜0.05).ELISA indicated that,compared with the OVX group,the MOX group showed a significant decrease in serum ALP activity and a significant increase in serum OCN content(P＜0.05).The miRNA sequencing result showed that 34 miRNAs were commonly expressed between the OVX group and the intervention group,and 15 miRNAs were commonly expressed between the OVX group and the intervention group.KEGG pathway enrichment analysis showed that the differentially expressed genes were mainly enriched in signaling pathways involving MAPK,Ras,FoxO,TNF,and cancer-related microRNAs.For the top five most differentially expressed microRNAs,namely miR-153-5p,miR-201-5p,miR-449c-5p,miR-451-3p,and miR-153-3p,target gene predictions yielded 10 major targets:Ebf2,Rtn4,Fbxl3,Naa15,Vamp2,Daam1,Akap6,Camta1,Ptprz1,and Lamp1.Conclusions Acupuncture slowed the progression of osteoporosis,improved bone microstructure,and balanced bone metabolism in rats.This therapeutic effect may be achieved through regulation of the expression of microRNAs and their target genes;however,the underlying mechanism requires further exploration.
