With the rapid development of the interdisciplinary area of artificial intelligence and medicine, large language model (LLM) has been widely used in the fields such as diagnosis and treatment, medicine, and healthcare. LLM has unique advantages in the field of traditional Chinese medicine (TCM), such as high consistency with the "Four Diagnostic Methods", perfect combination of natural language and self-supervised learning in TCM, the ability to adapt to the characteristics TCM formulas, and the assistance in TCM diagnosis and treatment. At present, various LLM models have been developed, including the "Qihuang Ask Big Model" and the Digital Traditional Chinese Medicine Big Model "GLM-130B", but they still face challenges such as value mismatch and medical abuse, increased demand for interpretability, lack of advanced technology, and domestic policy access. This article reviews the evolution of LLM, its unique advantages and applications in the field of TCM, the problems and challenges, and the future development trends, in order to providereference for the further promotion of LLM in traditional medicine.

"Target trial emulation" (TTE), as a new framework in real-world research, has been formally established in recent years. It can be used to guide the evaluation of the effectiveness and safety of medical interventions based on real-world data for observational causal inference. The core idea of this framework is to follow the principles of randomized controlled trial (RCT), emulate a corresponding RCT using real-world data, and then draw conclusions about the causal relationship between interventions and outcomes. The main implementation tips of TTE can be summarized as "3-7-2": 3 implementation steps including formulating the causal question, designing the emulation plan, and emulating the target study; 7 design elements including eligibility criteria, treatment strategies, intervention allocation, follow-up period, outcome, causal contrast of interest, and analysis plan; and control of 2 critical biases including immortal time bias and prevalent user bias. In this article, we present an overview of the development, current status, implementation steps, classic examples, advantages and limitations of TTE, and its application prospects in traditional Chinese medicine (TCM). It is hoped that this article can assist researchers in TCM to utilize this method for real-world research and contribute to the construction of a clinical evaluation system with distinctive features of TCM.

Objective:To discuss the mechanism of salidroside in the treatment of triple negative breast cancer(TNBC)by using the bioinformatics and network pharmacology methods,and to clarify the main targets and signaling pathways involved in the therapeutic effect.Methods:The dataset GSE45827 was obtained from the Gene Expression Omnibus(GEO)database;the gene set enrichment analysis(GSEA)was performed by using the R software package GSEABase;the differentially expressed genes(DEGs)between the adjacent normal tissue and TNBC tissue were identified by limma R software package;the Gene Ontology(GO)functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis were performed on the DEGs,and the DEGs were integrated with the drug targets to import into gene/protein interaction retrieval tool String database,and the protein-protein interaction(PPI)networks were constructed;the functional module screening of the PPI network was conducted by MCODE plugin,and the top 2 modules ranked by SCORE value were further subjected to GO functional enrichment analysis and KEGG signaling pathway analysis.The pathways obtained from the two rounds of KEGG enrichment analysis were intersected with the results of GSEA enrichment analysis to identify the pathways involved in the therapeutic effect of salidroside on TNBC.The top 10 key node genes in the highest scoring module determined by the maximum clique centrality(MCC)score caculated by CytoHubba plugi were considered as the core genes;the molecular docking was performed by AutoDock Vina1.1.2 and PyMOL2.3.0 Software.Results:The intersection of KEGG and GSEA enrichment analysis results showed 13 singaling pathways,including the cell cycle,cellular senescence,and p53 signaling pathways,and so on.The biological processes involved in the GO functional analysis,such as mitosis,nuclear division,and sister chromatid separation,were closely related to the cell cycle and consistented with the results of the KEGG signaling pathway enrichment analysis.The top ranked module based on the SCORE value contained 5 drug target genes of Rhodiola glycoside,such as cyclin A2(CCNA2),checkpoint kinase 1(CHEK1),kinesin family member 11(KIF11),DNA topoisomerase 2-alpha(TOP2A),and thymidylate synthase(TYMS).The molecular docking results demonstrated strong binding affinities between the above proteins and Rhodiola glycoside(binding energy<-7.0 kcal·mol-1).Conclusion:The tightly binding target of salidroside is located in the key functional modules of DEGs of TNBC,which can directly regulate by binding with CCNA2 and protein,and indirectly regulate the key differentially genes of TNBC by binding with KIF11,TOPA2,CHEK1 and TYMS proteins.Therefore,salidroside may be a potential clinical therapeutic drug for TNBC.

Objective:To explore the effect of Jian-Pi-Zhi-Dong decoction on autonomous activity and dopamine (dopamine, DA) synaptic vesicle protein expression in the striatum of Tourette syndrome (TS) model rats.Methods:The 4-week-old male SD rats were used to establish the TS model by intraperitoneal injection of N-aminodipropionate. Thirty successfully modeled rats were randomly divided into model group, Chinese medicine group, and tiberide group according to random number table method, with 10 rats in each group. And another 10 rats with matched body mass were selected as the control group. Rats in Chinese medicine group were given Jian-Pi-Zhi-Dong decoction solution (1.6 g/100 g) and the rats in tiapride group were given sulfate tiapride suspension (2.1 mg/100 g), while rats in control group and model group were given an equal volume of 0.9% sodium chloride solution, once a day for 4 weeks.The number of autonomous activities in rats was determined by autonomous activity programmer. ELISA was used to detect the level of DA in the striatum of rats and the expression of dopamine transporter (DAT).Vesicular monoamine transporter-2 (VMAT2) and α-synuclein (α-syn) were measured by Western blot.SPSS 25.0 software was used for data analysis. Multiple group comparisons were performed using one-way ANOVA, non-parametric test and repeated measures ANOVA.Results:Comparing the number of autonomous activities among the 4 groups, the interaction effect between time and group was significant ( F=184.354, P<0.001). At the 1-4 weeks of gavaging, the numbers of autonomic activities in the model group were more than those in the control group (all P<0.05).While the numbers of autonomic activities in Chinese medicine group and tiapride group were less than those in the model group (all P<0.05). Moreover, the numbers of autonomic activities in Chinese medicine group and tiapride group from 1 to 4 weeks were less than those after model making (all P<0.05). The Western blot results showed significant differences in the relative expression of α-syn ( H=29.098), DAT ( F=54.632) and VMAT2 ( H=18.982) among the 4 groups (all P<0.001). The expression levels of α-syn protein in Chinese medicine group and tiapride group were both lower than that in the model group (0.39(0.36, 0.51), 0.39(0.36, 0.50), 0.62(0.50, 0.70)) (both P<0.05). The expression level of DAT protein in Chinese medicine group was higher than that in the model group and lower than that in tiapride group ((0.37±0.06), (0.26±0.07), (0.49±0.09)) (both P<0.05). And the expression level of VMAT2 protein in Chinese medicine group had no significant difference compared with that in the model group ( P>0.05).The ELISA results showed significant differences in DA content of striatum among the 4 groups ( F=75.370, P<0.001). The level of DA in the model group was higher than that in the control group ((7.65±0.72) ng/L, (3.71±0.59) ng/L, P<0.05). The levels of DA in Chinese medicine group ((3.92±0.81) ng/L) and tiapride group ((4.40±0.53) ng/L) were lower than that in the model group (both P<0.05), and the difference between Chinese medicine group and tiapride group was not significant ( P>0.05). Conclusion:Jian-Pi-Zhi-Dong decoction can relieve the tic symptoms of the model rats with TS, and its mechanism may be related to inhibiting the excessive release of α-syn, improving the expression of DAT and VMAT2, improving the DA synaptic vesicle circulation, and reducing the DA content in the synaptic space of the brain.

To improve the current situation of multiple preoperative visits and evaluations for elderly patients and other patients with complex conditions, in December 2022, Peking Union Medical College Hospital established preoperative multidisciplinary evaluation clinic (shorted as joint clinic). The joint clinic established a multidisciplinary team, clarified service targets, and developed standardized clinic workflows to provide patients with a " one-stop" preoperative assessment(physical fitness assessment, nutritional assessment, and frailty assessment, etc.), nutritional optimization intervention, and prerehabilitation education and guidance services. This practice strengthened preoperative risk management, improved preoperative assessment efficiency, and ensured the safety of patients during the perioperative period. As of September 2023, the joint clinic had received a total of 128 patients, of which 86 underwent surgery after preoperative evaluation and prehabilitation optimization. The obesity rate, smoking rate, and number of frailty cases of these patients had decreased from 13.96%, 11.63%, and 18 at the time of visit to 9.30%, 4.65%, and 14 on the day before surgery, respectively. They had recovered well after surgery. This practice had improved the preoperative status of patients and created conditions for high-risk patients to undergo surgery smoothly, so as to provide references for other hospitals to carry out multidisciplinary collaborative preoperative evaluation works.

Evaluating the consistency of herb injectable formulations could improve their product quality and clinical safety, particularly concerning the composition and content levels of trace ingredients. Panax notoginseng Saponins Injection (PNSI), widely used in China for treating acute cardiovascular diseases, contains low-abundance (10%-25%) and trace saponins in addition to its five main constituents (notoginsenoside R₁, ginsenoside Rg₁, ginsenoside Re, ginsenoside Rb₁, and ginsenoside Rd). This study aimed to establish a robust analytical method and assess the variability in trace saponin levels within PNSI from different vendors and formulation types. To achieve this, a liquid chromatography-triple quadrupole mass spectrometry (LC-MS/MS) method employing multiple ions monitoring (MIM) was developed. A "post-column valve switching" strategy was implemented to eliminate highly abundant peaks (NR₁, Rg₁, and Re) at 26 min. A total of 51 saponins in PNSI were quantified or relatively quantified using 18 saponin standards, with digoxin as the internal standard. This study evaluated 119 batches of PNSI from seven vendors, revealing significant variability in trace saponin levels among different vendors and formulation types. These findings highlight the importance of consistent content in low-abundance and trace saponins to ensure product control and clinical safety. Standardization of these ingredients is crucial for maintaining the quality and effectiveness of PNSI in treating acute cardiovascular diseases.

【Objective】 To perform quantitative analysis on the sample provincial laws and regulations for voluntary blood donation, and provide reference for further revision of laws and regulations. 【Methods】 31 study samples were current provincial laws and regulations for voluntary blood donation that can be collected from open sources. The issue date and the revision date of each sample were recorded. With "The Blood Donation Law of the People’s Republic of China" as reference, 5 categories were formed and additional clauses in samples were coded and rated following content analysis procedures. Sample provinces were divided into two groups based on donation rate and their differences in evaluation scores of categories were examined using rank sum test. 【Results】 Until December, 2021, 31 sample provinces had issued and implemented provincial laws and regulation for voluntary blood donation, and 14 of which had been revised. Many detailed clauses (total score 9.32±3.09) were added in sample provincial laws and regulations, more clauses were added in the categories of 'related government agencies and their responsibilities’, 'management of clinical blood use’ and 'rewards and punishment’. Sample provinces were divided into two groups according to the donation rate per 1 000 people recommended by World Health Organization(10‰). Compared to lower donation rate group, the total score and sub score in the categories of 'basic principles’, 'management of blood collection and supply’ were significantly higher in higher donation rate group. 【Conclusion】 In revision and improvement of provincial laws and regulations, 'basic principles’ and 'management of blood collection and supply’ could be considered. This assay mainly tries to provide a new research perspective and perform quantitative analysis on content of sample provincial laws and regulation for voluntary blood donation, the actual effect of the results in this study need longer time to be examined, and we will keep following its new advances.

Objective:To explore the effect of mobile health (mHealth) management system on dietary behavior of patients with coronary heart disease (CHD) .Methods:Using the convenient sampling method, CHD patients who were hospitalized in Department of Cardiology of Beijing Anzhen Hospital and Beijing Chaoyang Hospital of Capital Medical University were selected as the research objects from June 2019 to January 2020. The research objects were randomly divided into the intervention group and the control group using SAS software. Finally, 68 cases in the intervention group and 66 cases in the control group completed the study. The intervention group received mhealth management, while the control group received routine management, and they were followed up to 1 month after discharge. The proportion of patients with the low-salt and low-oil diet, the intake of salt, oil, staple food, vegetables, fruits, fish, shrimp, poultry and eggs, BMI and blood pressure were compared between the two groups.Results:At 1 month follow-up, the intervention group was better than the control group in terms of low salt and low oil diet, salt intake, oil intake and vegetable intake compliance, and the differences were statistically significant ( P<0.05) . At 1 month follow-up, there were no statistically significant differences in BMI and blood pressure between two groups ( P>0.05) . Conclusions:The mobile health system can effectively increase the proportion of patients with a low-salt and low-oil diet, and improve the intake compliance of salt, edible oil and vegetables in patients with CHD. In future studies, the intervention time should be extended to further explore the long-term intervention effect of mobile health and give full play to the role of mobile health in continuous behavior management of patients with CHD after discharge.
