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 effect of Huanglian Jiedu Decoction on the intestinal flora of type 2 diabetes mellitus(T2DM) was investigated using 16S rRNA sequencing technology. Sixty rats were randomly divided into a normal group(10 rats) and a modeling group(50 rats). After one week of adaptive feeding, a high-fat diet + streptozotocin was given for modeling, and fasting blood glucose >16.7 mmol·L~(-1) was considered a sign of successful modeling. The modeling group was randomly divided into the model group, high-, medium-, and low-dose groups of Huanglian Jiedu Decoction, and metformin group. After seven days of intragastric treatment, the feces, colon, and pancreatic tissue of each group of rats were collected, and the pathological changes of the colon and pancreatic tissue of each group were observed by hematoxylin-eosin staining. The changes in the intestinal flora structure of each group were observed by the 16S rRNA sequencing method. The results showed that compared with the model group, the high-, medium-, and low-dose of Huanglian Jiedu Decoction reduced fasting blood glucose levels to different degrees and showed no significant changes in body weight. The number of islet cells increased, and intestinal mucosal damage attenuated. Alpha diversity analysis revealed that Huanglian Jiedu Decoction reduced the abundance and diversity of intestinal flora in rats with T2DM; at the phylum level, low-and mediam-dose of Huanglian Jiedu Decoction reduced the abundance of Bacteroidota, Proteobacteria, and Desulfobacterota and increased the abundance of Firmicute and Bacteroidota/Firmicutes, while the high-dose of Huanglian Jiedu Decoction increased the relative abundance of Proteobacteria and Bacteroidota/Firmicutes ratio, and decreaseal the relative; abundance of Firmicute; at the genus level, Huanglian Jiedu Decoction increased the relative abundance of Allobaculum, Blautia, and Lactobacillus; LEfse analysis revealed that the biomarker of low-and medium-dose groups of Huanglian Jiedu Decoction was Lactobacillus, and the structure of the intestinal flora of the low-dose group of Huanglian Jiedu Decoction was highly similar to that of the metformin group. PICRUSt2 function prediction revealed that Huanglian Jiedu Decoction mainly affected carbohydrate and amino acid metabolic pathways. It suggested that Huanglian Jiedu Decoction could reduce fasting blood glucose and increase the number of islet cells in rats with T2DM, and its mechanism of action may be related to increasing the abundance of short-chain fatty acid-producing strains and Lactobacillus and affecting carbohydrate and amino acid metabolic pathways.

Objective To investigate the predictive value of bone metabolism parameters on cardiac autonomic nervous system function in patients with type 2 diabetes mellitus(T2DM).Methods A total of 328 patients with T2DM hospitalized in the Department of Endocrinology of Gansu Provincial People's Hospital were enrolled in this study from October 2022 to October 2023.According to the serum 25(OH)D level,all the participants were divided into<10 ng/ml group(n=80),10～20 ng/ml group(n=173),and 20～30 ng/ml group(n=75).Biochemical indicators,bone metabolic parameters,left ventricular mass(LVM)and left ventricular mass index(LVMI)were compared.Time domain indicators ofheart rate variability(HRV)in 24 h holter electrocardiogram,including the global standard deviation of normal sinus RR interval(SDNN),sinus RR interval mean standard deviation(SDANN),and normal continuous sinus RR interval difference root mean square(RMSSD).Meanwhile,adjacent RR interval difference>50 ms as a percentage of the total inter-period(PNN50),HRV triangle index,standard deviation of the difference between the length of the entire adjacent NN interperiod(SDSD),and 24 h holter electrocardiogram HRV time-domain relevant indicators were compared among the three groups.The influence of bone metabolism parameters on cardiac autonomic nervous function and their correlation were analyzed,and the optimal cutting point of cardiac autonomic nervous function was predicted by receiver operating characteristic(ROC)curve.Results SBP,heart rate(HR),FPG,PWV,PTH and β-CTX in groups of 10 ng/ml,10～20 ng/ml and 20～30 ng/ml decreased in turn(P<0.05),while HDL-C,ABI,25(OH)D,Ca2+and PNN50 decreased.Correlation analysis between Spearman and Pearson showed that 25(OH)D was positively correlated with SDNN,HRV triangle index,PNN50 and rMSSD(P<0.01).Logistic regression analysis showed that 25(OH)D,Ca2+and HR were the influencing factors of cardiac autonomic nervous dysfunction in patients with T2DM.The ROC curve analysis showed that the areas under the ROC curve of 25(OH)D,Ca2+and HR were 0.791,0.607 and 0.629,respectively,with sensitivity of 73.4%,53.2%and 38.7%,and specificity of 74.0%,93.6%and 81.4%,respectively.Conclusions 25(OH)D is the influencing factor of cardiac autonomic nervous dysfunction in patients with T2DM,and patients with high degree of deficiency are more prone to cardiac autonomic nervous dysfunction.

Objective To elucidate the mechanism of Polygonatum kingianum water extract(PW)on the proliferation and colonization of Lactobacillus reuteri 1.2838,the differential expression of genes associated with proliferation,the quorum sensing signal molecule autoinducer-2(AI-2),and stress resistance were detected.Method L.reuteri 1.2838 was anaerobically cultured at 37℃in MRS medium supplemented with 0.0126 g·mL-1 PW,and the growth curve was subsequently plotted.The quantification of AI-2 production was conducted using the bioluminescence assay with Vibrio harveyi BB170.Transcriptome sequencing was executed using Illumina HiSeq technology,followed by the identification of differentially expressed genes.The expression profiles of these genes were analyzed,and real-time quantitative PCR was employed for validation.Results Incubation with PW resulted in increased proliferation and AI-2 production capacity of L.reuteri 1.2838.Transcriptome sequencing revealed 425 genes with significant differential expression,comprising 253 upregulated and 172 downregulated genes.Post GO and KEGG annotation analysis,genes related to L.reuteri 1.2838 proliferation,including pdhA,pshB,dlat,dld,genes pertinent to AI-2 production such as luxS,sec,and genes linked to the strain's stress resistance,groEL,groES,gltC,exhibited an upregulated expression pattern.Conclusion PW facilitates the proliferation and colonization of L.reuteri 1.2838 by influencing the tricarboxylic acid cycle,quorum sensing,and the strain's stress resistance,thus offering theoretical support for the development of both Polygonatum kingianum and Lactobacillus reuteri.

Objective To investigate the expression of inflammatory factors and brain-derived neurotro-phic factor(BDNF)in the brain hippocampus of Alzheimer's disease(AD)-like mice caused by amyloid β-protein 25-35(Aβ25-35).Methods A total of 40 six-week-old male Kunming mice were taken to construct an AD-like mouse model using bilateral ventricular injection of Aβ25-35,and were divided into the 0 d,7 d,14 d,and 28 d groups for observation,with 10 mice in each group.The Y-maze and new object recognition assay were used to test the learning and memory functions of the mice.The hematoxylin-eosin(HE)staining was used to observe the neuronal damage in the hippocampal region.Immunohistochemical staining was used to detect the expression levels of phosphorylated-tau(p-tau),CD11b and BDNF in hippocampus.ELISA was used to detect the expression levels of inflammatory factors in hippocampus,including interleukin-1β(IL-1β)and tumor necrosis factor-α(TNF)-α,and real-time quantitative reverse transcription PCR(RT-qPCR)and Western blot were used to detect the mRNA and protein expression levels of BDNF.Results Aβ25-35 could impair memory and cognitive function in the mice.Compared with the 0 d group,the neuron number in the hippocampal tissue of mice in the 14 d and 28 d groups was significantly reduced(P<0.05),and the optical density values of p-Tau and CD11b,and expression levels of IL-1β and TNF-α in the hippocampal region of mice in the 14 d and 28 d groups were significantly increased(P<0.05).In addition,compared with the 0 d group,the relative expression levels of BDNF mRNA and protein in the hippocampal tissue of mice were sig-nificantly increased in the 7 d group(P<0.05),while the relative expression levels of BDNF mRNA and pro-tein were significantly decreased in the 14 d and 28 d groups(P<0.05).Conclusion Aβ25-35 may increase the expression of TNF-α,IL-1β and p-tau in hippocampal tissue by activating microglia,which in turn impaired the memory and cognitive functions of mice,and the expression level of BDNF in hippocampal tissue showed a first increase and then a decrease in the injury period.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
