Objective: To map the research hotspots, developmental trends, and existing challenges in the integration of artificial intelligence (AI) with multi-omics in traditional Chinese medicine (TCM) through comprehensive bibliometric analysis. Methods: China National Knowledge Infrastructure (CNKI), Wanfang Data, China Science and Technology Journal Database (VIP), Chaoxing Journal Database, PubMed, and Web of Science were searched to collect literature on the theme of AI in TCM multi-omics research from the inception of each database to December 31, 2024. Eligible records were required to simultaneously address AI, TCM, and multi-omics. Quantitative and visual analyses of publication growth, core authorship networks, institutional collaboration patterns, and keyword co-occurrence were performed using Microsoft Excel 2021, NoteExpress v4.0.0, and Cite Space 6.3.R1. AI application modes in TCM multi-omics research were also categorized and summarized. Results: A total of 1 106 articles were enrolled (932 Chinese and 174 English). Publication output has increased continuously since 2010 and accelerated after 2016. Region-specific collaboration clusters were identified, dominated by Beijing University of Chinese Medicine, China Academy of Chinese Medical Sciences, Shanghai University of Traditional Chinese Medicine, and Nanjing University of Chinese Medicine. Keyword co-occurrence analysis revealed that current AI applications predominantly centered on metabolomics and algorithms such as cluster analysis and data mining. Research foci mainly ranked as follows: single herbs, herbal formulae, and disease-syndrome differentiation. Conclusion Machine learning methods are the predominant integrative modality of AI in the realm of TCM multi-omics research at present, utilized for processing omics data and uncovering latent patterns therein. The domain of TCM, in addition to investigating omics information procured through high-throughput technologies, also integrates data on traditional Chinese medicinal substances and clinical phenotypes, progressing towards joint analysis of multi-omics, high-dimensionality of data, and multi-modality of information. Deep learning approaches represent an emerging trend in the field.

Objective To explore the mechanism of protective effect of Jianpi Yichang Powder on intestinal mucosa by observing its effect on the expression of autophagy-related molecules in colon of ulcerative colitis(UC)model rats.Methods SD rats were randomly divided into normal group,model group,Jianpi Yichang Powder group and sulfasalazine group.UC rat model was established by 2,4,6-trinitrobenzene sulfonic acid/ethanol solution.After the model was successfully reproduced,the rats were given drugs orally once a day for 14 days.The general condition of rats was observed and the disease activity index(DAI)score was calculated.The pathological morphology of colonic tissue in all groups was observed by hematoxylin eosin(HE)staining.Autophagy of colonic epithelial cells was examined by transmission electron microscope.The expressions of myosin-like BCL2 interacting protein(Beclin1)and microtubule-associated protein 1 light chain 3(LC3)in colonic tissue were detected by immunofluorescence staining and Western Blot.The mRNA expressions of autophagy protein 5(Atg5),autophagy protein 7(Atg7)and ubiquitin-binding protein 62(p62)were detected by real-time quantitative polymerase chain reaction(Real-time PCR).Results Compared with the normal group,the general situation of the model group was worse,and the DAI score increased significantly(P<0.000 1).There was obvious epithelial cell damage in colonic tissue,and the number of autophagosomes decreased obviously under electron microscope.The expressions of Beclin1 and LC3-Ⅱ/LC3-Ⅰ protein as well as Atg5 and Atg7 mRNA in colonic tissue decreased significantly(P<0.000 1),while the expression of p62 mRNA increased significantly(P<0.000 1).Compared with the model group,the general condition of rats in Jianpi Yichang Powder group had recovered significantly,and the DAI score decreased significantly(P<0.000 1).Pathological damage of colonic tissue has been improved in different degrees,and the number of autophagosomes increased significantly under electron microscope.The expressions of Beclin1 and LC3-Ⅱ/LC3-Ⅰ protein as well as Atg5 and Atg7 mRNA in colonic tissue were significantly increased(P<0.01,P<0.001,P<0.000 1),while the expression of p62 mRNA was significantly decreased(P<0.01).Conclusion Jianpi Yichang Powder can protect UC colon mucosa from injury by up-regulating the expression of autophagy-related molecules including Beclin1,LC3,Atg5 and Atg7,down-regulating the expression of p62 and enhancing autophagy.

Objective To investigate the application efficiency and potential of CT radiomics in differentiating malignant and benign sub-centimeter solid pulmonary nodules. Methods A retrospective study was performed on the sub-centimeter ( ≤ 10 mm) solid pulmonary nodules detected by enhanced CT in our hospital from March 2020 to January 2023. Malignancy was confirmed by surgical pathology, and benignity was confirmed by surgical pathology or follow-up. Lesions were manually segmented and radiomic features were extracted. The feature dimension was reduced via feature correlation analysis and least absolute shrinkage and selection operator (LASSO). The 5-fold cross validation was used to validate the model. Support vector machine, logistic regression, linear classification support vector machine, gradient boosting, and random forest models were established for CT radiomics. Receiver operating characteristic curves were drawn. Delong test was used to compare the diagnostic performance of the five classifiers. The optimal model was selected and compared to radiologists with medium and high seniority. Results A total of 303 nodules, 136 of which were malignant, were examined. Radiomics models were established after feature extraction and selection. On test set, the areas under the receiver operating characteristic curves of support vector machine, logistic regression, linear classification support vector machine, random forest, and gradient boosting models were 0.922 (95%CI: 0.893, 0.950), 0.910 (95%CI: 0.878, 0.942), 0.905 (95%CI: 0.872, 0.938), 0.899 (95%CI: 0.865, 0.933), and 0.896 (95%CI: 0.862, 0.930), respectively. Delong test indicated no significant differences in the performance of the five radiomics models, and the support vector machine model showed the highest accuracy and F1 score. The support vector machine model showed significantly higher diagnostic accuracy as compared to radiologists (83.8% vs. 55.4%, P < 0.001). Conclusion The radiomics models achieved high diagnostic efficiency and may help to reduce the uncertainty in diagnosis of malignant and benign sub-centimeter solid nodules by radiologists.

During natural viewing, we often recognize multiple objects, detect their motion, and select one object as the target to track. It remains to be determined how such behavior is guided by the integration of visual form and motion perception. To address this, we studied how monkeys made a choice to track moving targets with different forms by smooth pursuit eye movements in a two-target task. We found that pursuit responses were biased toward the motion direction of a target with a hole. By computing the relative weighting, we found that the target with a hole exhibited a larger weight for vector computation. The global hole feature dominated other form properties. This dominance failed to account for changes in pursuit responses to a target with different forms moving singly. These findings suggest that the integration of visual form and motion perception can reshape the competition in sensorimotor networks to guide behavioral selection.
