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.

ObjectiveTo observe the changes in the levels of different subtypes of epidermal growth factor receptor (ErbB), namely ErbB1, ErbB2, ErbB3, and ErbB4, in the spinal dorsal horn of inflammatory pain model rats, and to explore their mechanism of mediating hyperalgesia as well as the intervention mechanism of electroacupuncture at "Zusanli (ST 36)" and "Kunlun (BL 60)". MethodsThe study was divided into five parts. In experiment 1, 14 Sprague Dawley (SD) rats were randomly divided into control and inflammatory pain group (7 rats each group) to observe the pain behavior and the protein expression of different ErbB receptor subtypes in the spinal dorsal horn. In experiment 2, 30 rats were randomly divided into control group 1, inflammatory pain group 1, and low-, medium-, and high-concentration TX1-85-1 groups, with 6 rats in each group, to observe the effect of inhibiting spinal ErbB3 on inflammatory pain. In experiment 3, 12 rats were randomly divided into control virus group and ErbB3 knockdown virus group, with 6 rats in each group, to observe the effect of knocking down ErbB3 in the spinal dorsal horn on inflammatory pain. In experiment 4, 44 rats were randomly divided into control group 2, inflammatory pain group 2, electroacupuncture group, and sham electroacupuncture group, with 11 rats in each group, to observe the effect of electroacupuncture. In experiment 5, 40 rats were randomly divided into control group 3, inflammatory pain group 3, electroacupuncture group 1, and electroacupuncture + NRG1 group, with 10 rats in each group, to observe the effect of activating ErbB3 on electroacupuncture. A rat model of inflammatory pain was established by subcutaneous injection of 100 μl of complete Freund's adjuvant into the sole of the unilateral hind foot of SD rats. Rats in the low-, medium-, and high-concentration TX1-85-1 groups were intrathecally injected with ErbB3 inhibitor TX1-85-1 on day 5 to day 7 after modeling. Rats in the ErbB3 knockdown virus group were injected with ErbB3 knockdown virus packaged with adenovirus vector-based short hairpin RNA (shRNA) into the spinal dorsal horn in situ 3 weeks before modeling. Rats in each electroacupuncture group received electroacupuncture at bilateral "Zusanli (ST 36)" and "Kunlun (BL 60)" from day 1 to day 7 after modeling, with dense-sparse waves at a frequency of 2 Hz/100 Hz and a current of 0.5-1.5 mA for 30 minutes once a day. Rats in the electroacupuncture + NRG1 group were intrathecally injected with ErbB3 ligand recombinant human neuregulin-1 (NRG1) after electroacupuncture intervention from day 5 to day 7 after modeling. The mechanical withdrawal threshold and thermal withdrawal latency of rats were measured on day 1, 3, 5, and 7 after modeling to evaluate behavior, and Western Blot was used to detect the protein and phosphorylation levels of each ErbB subtype in the spinal dorsal horn. ResultsCompared with the control group, rats in the inflammatory pain group showed decreased mechanical withdrawal threshold and thermal withdrawal latency of rats, and increased expression of phosphorylated ErbB3 (p-ErbB3) protein in the spinal dorsal horn on days 1, 3, 5, and 7 after modeling (P<0.01). On day 5 and day 7 after modeling, compared with the inflammatory pain group 1, the mecha-nical withdrawal threshold and thermal withdrawal latency of rats in the medium- and high-concentration TX1-85-1 groups increased, and the expression of p-ErbB3 protein decreased (P<0.05). On day 1, 3, 5, and 7 after modeling, compared with the control virus group, the mechanical withdrawal threshold and thermal withdrawal latency of rats in the ErbB3 knockdown virus group increased (P<0.05). On day 5 and day 7 after modeling, compared with the inflammatory pain group 2 and the sham electroacupuncture group, the mechanical withdrawal threshold and thermal withdrawal latency of rats in the electroacupuncture group increased, and the expression of p-ErbB3 protein decreased (P<0.05). On day 5 and day 7 after modeling, compared with the electroacupuncture + NRG1 group, the mechanical withdrawal threshold and thermal withdrawal latency of rats in the electroacupuncture group 1 increased (P<0.05). ConclusionThe p-ErbB3 in the spinal dorsal horn involved in hyperalgesia in rats with inflammatory pain, and electroacupuncture at "Zusanli (ST 36)" and "Kunlun (BL 60)" can alleviate inflammatory pain by inhibiting the expression of p-ErbB3 protein in the spinal dorsal horn of rats.

To explore the advantages of traditional Chinese medicine (TCM) and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications (DMC), refine key pathophysiological insights and treatment principles, and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine, hosted by the China Association of Chinese Medicine, was held in Beijing, 2024. Experts in TCM, Western medicine, and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis, diagnostic and treatment challenges, and mechanism research related to DMC, ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development, research prioritization, and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM, strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

OBJECTIVE To analyze the influencing factors for achieving target plasma drug concentration (trough) (abbreviated as “PDC”) of vancomycin in patients from high-altitude regions and establish a predictive model for PDC using single- center data, providing references for rational clinical drug use. METHODS Inpatients with vancomycin (1 g, q12 h) administered intravenously in our hospital from January 2021 to June 2024 were retrospectively included. Demographic data, liver and kidney function and hematological indexes were collected. Spearman correlation analysis was used to evaluate the correlation between vancomycin PDC and each detection index. Univariate analysis was used to evaluate the differences of each index in patients with different PDC, and the effects of different gender, body mass index, age and underlying diseases (hypertension/diabetes) on vancomycin PDC. Based on the results of correlation analysis and univariate analysis, multiple linear stepwise regression analysis was used to obtain the independent predictors of vancomycin PDC and construct the prediction model. RESULTS A total of 141 patients were included, with an overall attainment rate of 46.81% for the target PDC of vancomycin. Correlation analysis showed that the vancomycin PDC was positively correlated with age, blood urea nitrogen, uric acid (UA), serum creatinine (CRE) and β2- microglobulin (β2-MG), and negatively correlated with height, weight, creatinine clearance rate (CCR), glomerular filtration rate (GFR), alanine transaminase (ALT), hemoglobin (HGB), white blood cell count and neutrophils (P<0.05). There were significant differences in age, CRE and other 14 indexes among different PDC groups (P<0.05 or P<0.01). Age and underlying diseases had significant effects on vancomycin PDC (P<0.05 or P<0.01). CCR, direct bilirubin (DBil), β2-MG, UA, HGB and height (standardized coefficients were -0.371, 0.367, 0.169, 0.232, -0.140, -0.132; P<0.05) were independent predictors of vancomycin PDC. The F value of the regression equation was 34.858 (P<0.05), the R2 was 0.610, and the adjusted R2 was 0.592. CONCLUSIONS The vancomycin PDC of patients in high-altitude regions is affected by multiple factors such as renal function, liver function and hematological indexes. CCR, HGB and height could be used to predict vancomycin PDC negatively, while DBil, β2-MG and UA could be used to predict vancomycin PDC positively. The variables of the established prediction model could explain 59.2% of the variation of vancomycin PDC.

ObjectiveTo establish a rapid analytical method for identifying the differential components in Poria cocos medicinal materials based on ultra performance liquid chromatography-quadrupole-electrostatic field orbital trap high-resolution mass spectrometry(UPLC-Q-Orbitrap-MS), combined with mass defect filtering(MDF) and molecular network integration techniques. MethodsUPLC-Q-Orbitrap-MS was used for MS data acquisition and identification of P. cocos medicinal materials, with the help of MDF for the study of cleavage behavior and structural identification of triterpenoids. According to the similarity of MS/MS fragmentation patterns of each component, global natural product social molecular network(GNPS) was established, and Cytoscape 3.6.1 was used to screen molecular clusters with similar structures and the the structure of main compound classes were identified and confirmed. Multivariate statistical analyses such as principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA) were used to screen the differential components of the five P. cocos medicinal materials with the variable importance in the projection(VIP) value>1 and P<0.05 as the criteria. ResultsA total of 66 compounds were identified by database comparison, 8 compounds were newly identified by MDF, 28 compounds were newly identified by GNPS, and a total of 102 chemical compounds were identified, including 43 triterpenoids, 16 saccharides, 26 amino acids and peptides, 3 nucleosides, and 14 other compounds. Triterpenoids were predominant in Poriae Cutis and wild Fushen, amino acids and peptides were the most abundant in Poria and cultivated Fushen, carbohydrates were the most abundant in Poriae Cutis. Type Ⅰ and Ⅱ triterpenoids had higher amounts in Poria and cultivated Fushen, type Ⅲ triterpenoids were more abundant in Poriae Cutis, all four types of triterpenoids were higher in Fushenmu, and type Ⅰ, Ⅱ, and Ⅳ triterpenoids were higher in wild Fushen. A total of 12 common differential chemical constituents were screened, including serine, guanosine, gallic acid, 2-octenal, maltotriose, trametenolic acid, dehydroeburicoic acid, dehydrotrametenolic acid, poricoic acid A, poricoic acid B, poricoic acid E and G, but the relative contents of them varied significantly among different medicinal materials. ConclusionAmong the five P. cocos medicinal materials, the types of constituents are generally similar, but their relative contents differed significantly among these medicinal materials, especially in the distribution of triterpenoids. The integration of UPLC-Q-Orbitrap-MS, MDF and GNPS can provide a reference for the rapid qualitative analysis of other Chinese medicines.
