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 construct an intelligent model for literature screening, retrieval, and data extraction with a systematic review of coronary heart disease syndromes as an example, so as to improve the efficiency of evidence-based Chinese medicine research. MethodsBased on China National Knowledge Infrastructure (CNKI), VIP and Wanfang Data Resource System, the articles related to coronary heart disease syndrome research published from January 1, 2000 to December 31, 2023 were retrieved. Automated tools were used to batch retrieve paper metadata. Using text similarity algorithms, papers were merged, deduplicated, and subjected to preliminary screening based on titles and abstracts. Further screening was performed using object detection and image processing technologies on the full texts and statistical tables. Natural language processing (NLP) techniques and pre-trained models were applied to extract information. ResultsThe initial search retrieved 56 255 coronary heart disease syndrome-related articles. By artificial intelligence-assisted preliminary and secondary screening, the manual verification scope was narrowed to 1075 articles. Ultimately, 646 coronary heart disease syndrome related studies were included manually. With accuracy verification showing over 90% consistency in semantic recognition and element decomposition processes, we achieved data extraction and standardization processing for both basic literature information and 38 syndrome element statistics. ConclusionBy incorporating natural language processing, pre-trained models, artificial intelligence image processing and other technologies, this study enabled efficient retrieval, screening and standardized data extraction of Chinese medicine research literature.

The clinical practice guidelines of traditional Chinese medicine (TCM) have problems such as limited clinical application and unclear implementation effects, which may be related to the lack of clinical practice evidence. To provide reliable and precise evidence for clinical practice, this article proposes a model of combining TCM guidelines with real-world study, which includes 4 steps. Firstly, during the implementation process of the guidelines, a high-quality research database is established. Secondly, the recommendations in the guidelines are evaluated based on the established database in multiple dimensions, including applicability, effectiveness, safety, and cost-effectiveness, and thus their effectiveness in practical applications can be determined. Thirdly, based on the established database, core prescriptions are identified, and the targeted populations and medication plans are determined. That is, the best treatment regimen is established based on the analysis of abundant clinical data regarding the effects of different medication frequencies, dosages, and duration on efficacy. Fourthly, the guidelines are updated according to the real-world evidence. The research based on this model can provide real-world evidence for ancient and empirical prescriptions, improving their application in clinical practice. Moreover, this model can reduce research costs and improve research efficiency. When applying this model, researchers need to pay attention to the quality of real-world evidence, ensuring that it can truly reflect the situation in clinical practice. In addition, importance should be attached to the clinical application of guideline recommendations, ensuring that doctors can conduct standardized diagnosis and treatment according to the guidelines. Finally, full-process participation of multidisciplinary experts is encouraged to ensure the comprehensiveness and scientificity of the study. In conclusion, the application of this model will contribute to the development of TCM guidelines responsive to the needs of clinical practice and achieve the goal of promoting the homogenization of TCM clinical diagnosis and treatment.

As a supplement to randomized controlled trials, observational studies can provide evidence for the effectiveness of traditional Chinese medicine (TCM) treatment measures. They can also study influencing factors of diseases, etiology, and prognosis. However, there is a confounding effect due to the lack of randomization, which seriously affects the causal inference between the study factors and the outcome, resulting in confounding bias. Therefore, identifying and controlling confounding factors are key issues to be addressed in TCM observational studies. According to the causal network and the characteristics of TCM theory, confounding factors can be categorized into measured and unmeasured confounding factors. In addition, attention must be paid to identifying confounding factors and intermediate variables, as well as the interaction between confounding factors and study factors. For methods of controlling confounding factors, measured confounding factors can be controlled by stratification, multifactor analysis, propensity scores, and disease risk scores. Unmeasured and unknown confounding factors can be corrected using instrumental variable methods, difference-in-difference methods, and correction for underlying event rate ratios. Correcting and controlling confounding factors can ensure a balance between groups, and confounding bias can be reduced. In addition, methods such as sensitivity analysis and determination of interactions make the control of confounding factors more comprehensive. Due to the unique characteristics of TCM, observational studies of TCM face unique challenges in identifying and controlling confounding factors, including the ever-changing TCM treatment measures received by patients, the often-overlooked confounding effects in the four diagnostic information of TCM, and the lack of objective criteria for TCM evidence-based diagnosis. Some scholars have already conducted innovative explorations to address these issues, providing a methodological basis for conducting higher-quality TCM observational studies, so as to obtain more rigorous real-world evidence of TCM and gradually develop quality evaluation criteria for OS that are consistent with the characteristics of TCM.
