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.

Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance, while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine (TCM) has a long history in the prevention and management of this condition, demonstrating eight distinct advantages, including systematic theoretical foundation, diversified therapeutic approaches, definite therapeutic efficacy, high safety profile, good patient compliance, comprehensive intervention strategies, emphasis on prevention, and stepwise treatment protocols. Additionally, TCM is characterized by six distinctive features: the use of natural medicinal substances, non-invasive external therapies, integration of medicinal dietetics, simple exercise regimens, precise syndrome differentiation, and diverse dosage forms. By combining internal and external treatments, TCM facilitates individualized regimen adjustment and holistic regulation, demonstrating remarkable effects in improving obesity-related metabolic indicators, regulating constitutional imbalance, and promoting healthy behaviors. However, challenges remain, such as inconsistent operational standards, insufficient high-quality clinical evidence, and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment, conducting multicenter randomized controlled trials, and fostering interdisciplinary integration, so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

ObjectiveTo investigate the association between immunoglobulin G (IgG)/immunoglobulin M (IgM) ratio and prognosis in patients with initially unresectable hepatocellular carcinoma (iuHCC) receiving TTP triple therapy with transcatheter arterial chemoembolization (TACE), tyrosine kinase inhibitor (TKI), and programmed cell death protein-1 (PD-1) inhibitors. MethodsA retrospective analysis was performed for the clinical data of 151 iuHCC patients who received TTP triple therapy in Department of Hepatobiliary Surgery, Guangxi Medical University Cancer Hospital, from November 2019 to December 2022, and according to IgG/IgM ratio, they were divided into high IgG/IgM group (IgG/IgM ratio >13.23) and low IgG/IgM group (IgG/IgM ratio ≤13.23). The t-test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. The Kaplan-Meier method and the log-rank test were used for survival analysis, and the Cox proportional hazards model was used to investigate the potential influencing factors for overall survival (OS). ResultsThe 151 patients had a median OS of 26.7 months (95% confidence interval [CI]: 19.8-not reached) and a median progression-free survival of 12.5 months (95%CI: 10.4 — 15.8). The objective response rate was 83.4% and the disease control rate was 94.0%. There were no significant differences in baseline data between the high IgG/IgM group and the low IgG/IgM group (all P>0.05). There was a significant difference in median OS between the high IgG/IgM group and the low IgG/IgM group (20.6 months vs not reached, P=0.016). In both the high IgG/IgM group and the low IgG/IgM group, salvage hepatectomy was significantly associated with the improvement in OS (χ2=8.297 and 10.307, both P<0.05). The multivariate analysis showed that high IgG/IgM ratio (hazard ratio [HR]=1.799, 95%CI: 1.077 — 3.006, P=0.025), baseline alpha-fetoprotein >400 ng/mL (HR=1.762, 95%CI: 1.017 — 3.050, P=0.043), and BCLC stage (HR=2.265, 95%CI: 1.212 — 4.232, P=0.010) were independent influencing factors for OS. ConclusionHigh IgG/IgM ratio is associated with a poorer prognosis in iuHCC patients receiving TTP triple therapy, and salvage hepatectomy has a potential value in improving the prognosis of patients with a high IgG/IGM ratio.

ObjectiveTo investigate the inhibitory effect of Biejiajian Pills (BJJW) on the growth of liver cancer, as well as its potential mechanism in mediating the AMP-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) pathway through mitochondrial energy metabolism. MethodsHuman hepatoma Huh7 cells were used to establish a nude mouse model of subcutaneous xenograft tumor. A total of 18 tumor-bearing nude mice were randomly divided into model group, BJJW group (2.2 g/kg), and metformin group (250 mg/kg), and the corresponding drug was given by gavage for 14 consecutive days. Tumor volume and weight were monitored during the experiment; HE staining was used to observe histopathological changes; the levels of reactive oxygen species (ROS) and adenosine triphosphate (ATP) in tumor tissue were measured; immunohistochemistry and Western blotting were used to measure the expression levels of proteins associated with the AMPK/mTOR pathway. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the Tukey’s test was used for further comparison between two groups; the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups, and the Dunn’s test was used for further comparison between two groups. ResultsCompared with the model group, the BJJW group had a tumor inhibition rate of 45.73%, with significant reductions in both tumor volume and weight (P<0.01). Pathological examination showed that compared with the model group, the BJJW group had a significant reduction in the number of tumor cells and the presence of extensive necrosis. Mechanistic studies showed that compared with the model group, the BJJW group had a significant increase in ROS level (P<0.001) and a significant reduction in ATP level (P<0.001), as well as significant increases in p-AMPK/AMPK ratio (0.81±0.20 vs 0.13±0.04, P<0.01) and p-ULK1/ULK1 ratio (0.69±0.17 vs 0.18±0.13, P<0.01) and a significant reduction in p-mTOR/mTOR ratio (1.34±0.16 vs 3.20±0.62, P<0.01). ConclusionBJJW may inhibit the growth of liver cancer by inducing mitochondrial energy metabolism dysfunction, increasing the level of ROS, reducing the level of ATP, and activating the AMPK/mTOR signaling pathway.

ObjectiveTo investigate the expression level of HBV cccDNA in patients in the convalescence stage of hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF) and its correlation with HBV markers and liver histopathological changes. MethodsA total of 30 patients in the convalescence stage of HBV-ACL who were hospitalized in The Ninth Hospital of Nanchang from January 2015 to October 2023 were enrolled as liver failure group, and 9 patients with chronic hepatitis B (CHB), matched for sex and age, were enrolled as control group. The content of HBV cccDNA in liver tissue was measured, and its correlation with clinical data and laboratory markers was analyzed. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups, and a one-way analysis of variance or the Kruskal-Wallis H test was used for comparison between multiple groups; the Fisher’s exact test was used for comparison of categorical data between groups. A Spearman correlation analysis was performed. ResultsThe liver failure group had a significantly lower content of HBV cccDNA in liver tissue than the control group (-0.92±0.70 log10 copies/cell vs -0.13±0.91 log10 copies/cell, t=2.761, P=0.009). In the liver failure group, there was no significant difference in the content of HBV cccDNA in liver tissue between the HBeAg-positive patients and the HBeAg-negative patients (P>0.05); there was no significant difference in the content of HBV cccDNA in liver tissue between the patients with different grades (G0-G2, G3, and G4) of liver inflammatory activity (P>0.05); there was no significant difference in the content of HBV cccDNA in liver tissue between the patients with different stages (S0-S2, S3, and S4) of liver fibrosis (P>0.05); there was no significant difference in the content of HBV cccDNA in liver tissue between the patients with negative HBV DNA and those with positive HBV DNA (P>0.05). For the liver failure group, the content of HBV cccDNA in liver tissue was positively correlated with the content of HBV DNA in liver tissue (r=0.426, P=0.043) and was not significantly correlated with the content of HBV DNA in serum (P>0.05). ConclusionThere is a significant reduction in the content of HBV cccDNA in liver tissue in the convalescence stage of HBV-ACLF. HBV cccDNA exists continuously and stably in liver tissue and can better reflect the persistent infection and replication of HBV than HBV DNA in serum and liver tissue.

BACKGROUND:Stroboscopic visual training can force sensory reweighting to restore the original weights by increasing sensitivity to proprioceptive information,which may be an effective method to improve proprioception. OBJECTIVE:To determine the effects of balance training in three conditions,low frequency,high frequency and normal vision,on ankle proprioception in patients with chronic ankle instability. METHODS:Thirty-six patients with chronic ankle instability recruited from the students of Southwest Medical University were randomly assigned to a low-frequency vision training group,a high-frequency vision training group,and a normal vision training group,with 12 subjects in each group.Subjects in the three groups underwent progressive hop stabilization and balance training,in which the low-frequency vision training group and the high-frequency vision training group wore stroboscopic spectacles during the training,with a stroboscopic frequency of 1.75 and 5 Hz,respectively.The training in each group was performed three times a week for 4 consecutive weeks.Assessments,including ankle proprioception,ankle stability self-assessment and dynamic postural stability,were performed before training and within 1 week after the completion of training. RESULTS AND CONCLUSION:There was a significant main effect of time factor in ankle proprioception(P<0.05).Compared with the pre-training period,subjects in the low-frequency vision training group and the high-frequency vision training group showed significant improvement in ankle proprioception after 4 weeks of training(P<0.05);and subjects in the low-frequency vision training group showed a significant improvement in ankle proprioception compared with that of the normal vision training group after 4 weeks of training(P<0.05).There were significant main effects of time factor and group×time interaction in ankle proprioception(P<0.05).Compared with the pre-training period,the ankle stability self-assessment in all three groups was improved after 4 weeks of training(P<0.05).And the ankle stability self-assessment in high-frequency visual training group was higher than that in normal vision training group after 4 weeks of training(P<0.05).Compared with the pre-training period,subjects in the low-frequency vision training group and the high-frequency vision training group showed significant improvements in forward dynamic postural stability,posteromedial dynamic postural stability,and posterolateral dynamic postural stability after 4 weeks of training(P<0.05),while in the normal vision training group,forward dynamic postural stability and posterolateral dynamic postural stability were significantly improved after 4 weeks of training(P≤0.05).To conclude,balance training under stroboscopic visual conditioning improves proprioception,ankle stability self-assessment,and dynamic postural stability in patients with chronic ankle instability regardless of frequency.

BACKGROUND:Fibromyalgia syndrome,as a common rheumatic disease,is related to central sensitization and immune abnormalities.However,the specific mechanism has not been elucidated,and there is a lack of specific diagnostic markers.Exploring the possible pathogenesis of this disease has important clinical significance. OBJECTIVE:To screen the potential diagnostic marker genes of fibromyalgia syndrome and analyze the possible immune infiltration characteristics based on bioinformatics methods,such as weighted gene co-expression network analysis(WGCNA),and machine learning. METHODS:Gene expression profiles in peripheral serum of fibromyalgia syndrome patients and healthy controls were obtained from the gene expression omnibus(GEO)database.The differentially co-expressed genes were screened in the expression profile by differential analysis and WGCNA analysis.Least absolute shrinkage and selection operator(LASSO)and support vector machine-recursive feature elimination(SVM-RFE)machine learning algorithm were further used to identify hub biomarkers,and draw receiver operating characteristic curve(ROC)to evaluate the accuracy of diagnosing fibromyalgia syndrome.Finally,single sample gene set enrichment analysis(ssGSEA)and gene set enrichment analysis(GSEA)were used to evaluate the immune cell infiltration and pathway enrichment in patients with fibromyalgia syndrome. RESULTS AND CONCLUSION:Eight down-regulated differentially expressed genes(DEGs)were obtained after differential analysis of the GSE67311 dataset according to the conditions of log2|(FC)|>0 and P<0.05.After WGCNA analysis,497 genes were included in the module(MEdarkviolet)with the highest positive correlation(r=0.22,P=0.04),and 19 genes were included in the module(MEsalmon2)with the highest negative correlation(r=-0.41,P=6×10-5).After intersecting DEGs and the module genes of WGCNA,seven genes were obtained.Four genes were screened out by LASSO regression algorithm and five genes were screened out by SVM-RFE machine learning algorithm.After the intersection of the two,three core genes were identified,which were germinal center associated signaling and motility like,integrin beta-8,and carboxypeptidase A3.The areas under the ROC curve of the three core genes were 0.744,0.739,and 0.734,respectively,indicating that they have good diagnostic value and can be used as biomarkers for fibromyalgia syndrome.The results of immune infiltration analysis showed that memory B cells,CD56 bright NK cells,and mast cells were significantly down-regulated in patients with fibromyalgia syndrome compared with the control group(P<0.05),and were significantly positively correlated with the above three biomarkers(P<0.05).The enrichment analysis suggested that there were nine fibromyalgia syndrome enrichment pathways,mainly related to olfactory transduction pathway,neuroactive ligand-receptor interaction,and infection pathway.The above results showed that the occurrence and development of fibromyalgia syndrome are related to the involvement of multiple genes,abnormal immune regulation,and multiple pathways imbalance.However,the interactions between these genes and immune cells,as well as their relationships with various pathways need to be further investigated.

ObjectiveTo clarify the anti-inflammatory and lung-protective effects of Yantiao prescription on lipopolysaccharide (LPS)-induced acute lung injury (ALI), and to explore the impact of Yantiao prescription on the metabolic pathways of arachidonic acid (AA) in vivo. MethodsThirty male C57BL/6J mice were randomly divided into the following groups based on body weight: normal group, model group, dexamethasone group (2 mg·kg-1), low-dose Yantiao prescription group (18 g·kg-1), and high-dose Yantiao prescription group (36 g·kg-1), with 6 mice in each group. The ALI mouse model was established by intraperitoneal injection of LPS. The treatment groups received oral gavage once a day for 7 consecutive days, and serum and lung tissue were collected at the end of the experiment. The content of pro-inflammatory cytokines tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in serum was detected by enzyme-linked immunosorbent assay (ELISA). Hematoxylin-eosin (HE) staining was used to assess lung tissue pathology. The wet/dry weight ratio (W/D) and myeloperoxidase (MPO) activity in lung tissue were measured. The content of AA metabolites in serum and lung tissue was measured by liquid chromatography triple quadrupole-mass spectrometry (LC-MS/MS). ResultsCompared with the conditions in the normal group, the content of serum pro-inflammatory cytokines TNF-α, IL-1β, and IL-6 in the model group was significantly increased (P<0.01). The alveolar structure in mice was severely damaged, with markedly thickened alveolar walls and extensive inflammatory cell infiltration. The W/D ratio and MPO activity in lung tissue were significantly increased (P<0.01). The content of AA metabolites, including prostaglandin D2 (PGD2), prostaglandin E2 (PGE2), 11(S)-hydroxy-eicosatetraenoic acid [11(S)-HETE], and 5-hydroxy-eicosatetraenoic acid (5-HETE) in serum and lung tissue was significantly increased (P<0.05), while the content of 11,12-epoxyeicosatrienoic acid (11,12-EET) and 14,15-epoxyeicosatrienoic acid (14,15-EET) in serum was significantly decreased (P<0.01). Compared with the results in the model group, the content of serum pro-inflammatory cytokines TNF-α, IL-1β, and IL-6 in the dexamethasone group, low-dose Yantiao prescription group, and high-dose Yantiao prescription group was significantly reduced (P<0.05). Mild thickening of alveolar walls, scattered inflammatory cell infiltration, and relatively intact tissue structure with improved alveolar architecture were observed. The W/D ratio and MPO activity in lung tissue were significantly reduced (P<0.01). The content of AA metabolites PGD2, PGE2, 11(S)-HETE, and 5-HETE in serum from the dexamethasone group was significantly decreased (P<0.05), while the content of 14,15-EET in serum significantly increased (P<0.01), and the content of 5-HETE in lung tissue significantly decreased (P<0.01). In the low-dose and high-dose Yantiao prescription groups, the content of AA metabolites PGD2, PGE2, 11(S)-HETE, and 5-HETE in serum and lung tissue was significantly decreased (P<0.05), while the content of 11,12-EET in both serum and lung tissue was significantly increased (P<0.05). ConclusionYantiao prescription has significant protective effects against LPS-induced ALI, which are related to its regulation of AA metabolic pathways in vivo.

ObjectiveTo evaluate the therapeutic effects of modified Buwangsan on cognitive dysfunction in the rat model of type 2 diabetes mellitus with mild cognitive impairment (T2DM-MCI) and explore the underlying mechanism. MethodsThirty-six 5-week-old SPF-grade SD rats were randomly assigned into 6 groups: Normal (Con, fed with a normal diet), model (DM, fed with a high-sugar and high-fat diet), low-dose modified Buwangsan (L-BWS, 1.86 g·kg-1), medium-dose modified Buwangsan (M-BWS, 3.72 g·kg-1), high-dose modified Buwangsan (H-BWS,7.44 g·kg-1), and huperzine A (SSJJ, 0.018 mg·kg-1). The rats were treated by gavage once a day for 12 weeks. The body weight and blood glucose level were monitored dynamically. Morris water maze was employed to test the cognitive function of rats. Hematoxylin-eosin and Nissl staining were employed to observe the pathological changes of the hippocampus. The levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in the serum and hippocampus were assessed by enzyme-linked immunosorbent assay. Western blotting was employed to determine the expression levels of key autophagy-related proteins including microtubule-associated protein 1 light chain 3 (LC3), type Ⅲ phosphatidylinositol 3-kinase complex regulatory subunit (Beclin1), and phosphorylated UNC-51-like kinase (p-ULK) 1/2 in the hippocampus. Immunofluorescence staining was employed to observe the regulation of p-PI3K/PI3K, p-mTOR/mTOR, and p-Akt/Akt ratios. ResultsCompared with the DM group, the L-BWS, M-BWS, H-BWS, and SSJJ groups showed increases in body weight at the end of the experiment (P<0.05), and the M-BWS, H-BWS and SSJJ groups showed declines in fasting blood glucose level (P<0.05). In the water maze test, compared with the DM group, the M-BWS, H-BWS, and SSJJ groups presented shortened escape latency (P<0.001). The L-BWS, M-BWS, H-BWS, and SSJJ group showcased regularly arranged cells in the hippocampus and cortex, markedly increased number of neurons, and significantly recovered Nissl bodies. Compared with the DM group, the L-BWS, M-BWS, H-BWS, and SSJJ groups had reductions in the levels of IL-1β and IL-6 in the serum and hippocampus (P<0.05), increases in the LC3-II/LC3-I ratio and expression level of beclin1 in the hippocampus (P<0.05) and the p-ULK level (P<0.05). The p-PI3K/PI3K, p-Akt/Akt, and p-mTOR/mTOR ratios in the hippocampus decreased in the M-BWS, H-BWS, and SSJJ groups (P<0.01). ConclusionModified Buwangsan significantly ameliorates cognitive dysfunction and neurological damage in the rat model of T2DM through multiple mechanisms. It regulates metabolic disorders, lowers the blood glucose level, improves lipid metabolism, and alleviates oxidative stress. It promotes the protection and repair of neurons by inhibiting inflammatory responses and activating the autophagy pathway in the hippocampus. At the same time, modified Buwangsan relieves autophagy inhibition by regulating the PI3K/Akt/mTOR signaling pathway to alleviate the brain tissue injury.
