Traditional Chinese medicine (TCM) represents a paradigmatic approach to personalized medicine, developed through the systematic accumulation and refinement of clinical empirical data over more than 2000 years, and now encompasses large-scale electronic medical records (EMR) and experimental molecular data. Artificial intelligence (AI) has demonstrated its utility in medicine through the development of various expert systems (e.g., MYCIN) since the 1970s. With the emergence of deep learning and large language models (LLMs), AI's potential in medicine shows considerable promise. Consequently, the integration of AI and TCM from both clinical and scientific perspectives presents a fundamental and promising research direction. This survey provides an insightful overview of TCM AI research, summarizing related research tasks from three perspectives: systems-level biological mechanism elucidation, real-world clinical evidence inference, and personalized clinical decision support. The review highlights representative AI methodologies alongside their applications in both TCM scientific inquiry and clinical practice. To critically assess the current state of the field, this work identifies major challenges and opportunities that constrain the development of robust research capabilities-particularly in the mechanistic understanding of TCM syndromes and herbal formulations, novel drug discovery, and the delivery of high-quality, patient-centered clinical care. The findings underscore that future advancements in AI-driven TCM research will rely on the development of high-quality, large-scale data repositories; the construction of comprehensive and domain-specific knowledge graphs (KGs); deeper insights into the biological mechanisms underpinning clinical efficacy; rigorous causal inference frameworks; and intelligent, personalized decision support systems.

Neuropathic pain is frequently comorbidity with cognitive deficits. Neuralized1 (Neurl1)-mediated ubiquitination of CPEB3 in the hippocampus is critical in learning and memory. However, the role of Neurl1 in the cognitive impairment in neuropathic pain remains elusive. Herein, we found that lumbar 5 spinal nerve ligation (SNL) in male rat-induced neuropathic pain was followed by learning and memory deficits and LTP impairment in the hippocampus. The Neurl1 expression in the hippocampal CA1 was decreased after SNL. And this decrease paralleled the reduction of ubiquitinated-CPEB3 level and reduced production of GluA1 and GluA2. Overexpression of Neurl1 in the CA1 rescued cognitive deficits and LTP impairment, and reversed the reduction of ubiquitinated-CPEB3 level and the decrease of GluA1 and GluA2 production following SNL. Specific knockdown of Neurl1 or CPEB3 in bilateral hippocampal CA1 in naïve rats resulted in cognitive deficits and impairment of synaptic plasticity. The rescued cognitive function and synaptic plasticity by the treatment of overexpression of Neurl1 before SNL were counteracted by the knockdown of CPEB3 in the CA1. Collectively, the above results suggest that the downregulation of Neurl1 through reducing CPEB3 ubiquitination and, in turn, repressing GluA1 and GluA2 production and mediating synaptic plasticity impairment in hippocampal CA1 leads to the genesis of cognitive deficits in neuropathic pain.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective To develop and validate a prediction model for risk of amputation in patients with diabetic foot ulcers(DFU)based on systematic review and meta-analysis.Methods The studies on the risk factors of amputation in DFU patients was retrieved by using subject words+free words.After screening,37 cohort studies were finally included,and the Newcastle-Ottawa scale(NOS)was used for quality evaluation.Meta-analysis was performed on the risk factors of amputation in DFU.Then a prediction model for DFU amputation risk were constructed based on the statistically significant risk factors in the meta-analysis.The corresponding β value was calculated based on the combined odds ratio(OR)value of each risk factor,and each risk factor was scored to establish a scoring system model.The clinical data of 453 DFU patients hospitalized in our department from 2021 to 2023 were collected as a validation cohort.Receiver operating characteristic(ROC)curve analysis was used to evaluate the model performance.The area under the curve(AUC)was calculated,and the optimal cutoff score was determined by calculation of the maximum Youden index through sensitivity and specificity.Results Our meta-analysis showed a cumulative amputation rate of approximately 34.65%in 11 779 DFU patients.The final risk prediction models include gangrene[OR=11.92(5.86～24.24)],ulcer depth[OR=4.93(2.52～9.64)],osteomyelitis[OR=3.19(2.36～4.29)],previous amputation history[OR=3.19(2.00～5.09)]and lower extremity arterial disease[OR=3.10(2.31～4.17)].According to the weights of each risk factor,the total score of the model is 76,and the optimal cut-off score is 36.5.The prediction model performed well,with an AUC value of 0.864(0.824,0.903),a sensitivity of 0.743,a specificity of 0.859,and an accuracy rate of 83.00%.Conclusion A prediction model for DFU amputation risk is developed based on risk factor scoring,and has good discrimination and calibration,providing effective scientific basis for clinical research and clinical decision-making related to DFU amputation.

Objective To assess the evolving disease burden of esophageal and gastric cancers in China from 1990 to 2021, with a focus on gender disparities, and construct a predictive model to forecast disease trends from 2022 to 2031, aiming to optimize targeted prevention strategies. Methods Epidemiological data for esophageal and gastric cancers in China (1990-2021) were extracted from the Global Burden of Disease (GBD) 2021 database. Temporal trends were analyzed using Joinpoint regression (version 4.9.1.0), and future trends were predicted via the GM (1, 1) model under grey system theory. Results From 1990 to 2021, tobacco- and alcohol-attributable burdens of esophageal cancer increased, while tobacco- and diet-related burdens of gastric cancer showed no significant change. Deaths and disability-adjusted life years (DALY) for esophageal cancer rose by 40.61% and 17.89%, respectively; gastric cancer deaths increased by 18.95%, though DALY decreased by 1.22%. Both cancers exhibited significant declines in age-standardized mortality rates (−45.78% for esophageal cancer, −53.29% for gastric cancer) and age-standardized DALY rates (−51.45% for esophageal cancer, −57.58% for gastric cancer). China’s age-standardized mortality and DALY rates for both cancers remained consistently higher than global averages. Males exhibited disproportionately higher burdens than females. Predictive modeling projected continued but decelerating declines in disease burdens for both cancers by 2031. Conclusion Over three decades, China achieves measurable reductions in esophageal and gastric cancer burdens, though gastric cancer burdens remain higher than esophageal cancer. Persistent disparities relative to global levels, elevated male burdens, and aging demographics highlight the urgency for prioritized interventions targeting high-risk populations.

OBJECTIVE To screen potential adverse drug event （ADE） signals for the treatment of multiple sclerosis （MS） with ofatumumab， and to provide reference for the safe use of drugs in clinical practice. METHODS Using “ofatumumab” and the trade name “Kesimpta” as the search keywords， adverse event （AE） reports related to ofatumumab included in FDA Adverse Event Reporting System database from January 2009 to December 2023 were screened， and their reason contained the “multiple sclerosis”； ADE signal mining and analysis were conducted by reporting odds ratio method and proportional reporting ratio method. RESULTS A total of 21 759 eligible AE reports were selected， involving 62 449 AE cases； 27 system organ classes included general diseases and various reactions at the site of administration （15 021 cases）， neurological diseases （9 668 cases）， infectious and invasive diseases （5 967 cases）， injury， poisoning and surgical complications （4 952 cases）， musculoskeletal and connective tissue disorders （4 647 cases）. A total of 21 759 AE reports correspond to 606 ADE signals， including 234 ADE positive signals. A total of 107 ADE positive signals were not included in drug instruction of ofatumumab， including flu-like diseases， nasopharyngitis， cough， urinary tract infection， sore throat， insomnia， runny nose， anemia， hair loss， atrial fibrillation， and thrombocytopenia， etc. CONCLUSIONS In the process of using ofatumumab for MS， sufficient attention should be paid to ADE included in drug instructions. The ADE with strong signal strength screened in this study should also be paid special attention to， such as flu-like diseases， hemocytopenia， temperature intolerance， optic neuritis， and moyamoya disease. The increased risk of infection， cardiovascular disease， and potential damage to the respiratory and spiritual systems caused by ofatumumab can not be ignored.

Objective:To analyze the prenatal characteristics and pregnancy outcomes of fetuses with 17q12 microdeletion or microduplication.Methods:From January 2018 to December 2022, 14 fetuses diagnosed with 17q12 microdeletion and three with 17q12 microduplication by chromosomal microarray analysis folloning invasive prenatal diagnostic techniques at Nanjing Maternity and Child Health Care Hospital were retrospectively enrolled in this study. Relevant articles up to February 1, 2023, were retrieved from PubMed, Embase, China National Knowledge Infrastructure, Wanfang database, and Yiigle with the terms "17q12 microdeletion", "17q12 microduplication", "prenatal diagnosis", and "pregnancy outcome". Eighty-four 17q12 microdeletion cases and fourteen 17q12 microduplication cases were retrieved. Prenatal ultrasound features and pregnancy outcomes of those fetuses were analyzed and summarized.Results:In this study, ninety-eight 17q12 microdeletion cases and seventeen 17q12 microduplication cases were analyzed. (1) 17q12 microdeletion: The prenatal ultrasound showed all the 17q12 microdeletion cases had renal abnormalities (100.0%, 98/98), and renal hyperechogenicity was detected in 81.6% (80/98) of them; pedigree analysis suggested that 74.2% (49/66) mutations were de novo; 64.1% (41/64) of pregnant women chose to terminate the pregnancy and 35.9%(23/64) chose to continue pregnancy; eight out of 12 live births who were followed up had different degrees of abnormalities and four were normal during the follow-up period. (2) 17q12 microduplication: Among the 17 fetuses, 10 had upper gastrointestinal obstruction; pedigree analysis suggested that four were de novo mutations (4/13); nine out of 14 pregnant women with reported pregnancy outcomes chose to terminate the pregnancy, and five continued the pregnancy to delivery; follow up of the live births found that four neonates were normal and one had a good prognosis after surgery. Conclusions:Fetuses with 17q12 microdeletion often show renal hyperechogenicity in ultrasound images, and most mutations were de novo with poor prognosis. 17q12 microduplication in fetuses is often characterized by upper gastrointestinal obstruction, and most inherited from their parents.

Objective To investigate the effect of sperm-associated antigen 6(Spag6)on cerebral edema secondary to ische-mia-reperfusion in rats.Methods Ninety SD rats were randomly assigned to three groups:sham operation group,model group,and experimental group.The rats were treated with lentivirus injection and middle cerebral artery embolization.The infarct vol-ume was evaluated by using 2,3,5-triphenyltetrazolium chloride(TTC)staining.Hematoxylin and eosin(HE)staining was used to observe the damage of ependymal cells and cilia.Scanning electron microscope was used to observe the activity of motile cili-a.Transmission electron microscopy was used to abserve the ultrastructure of nerve cells.The expressions of apoptosis-related proteins Bcl-2,Bax,Survivin,GluN1,GluN2B,and GluA2 were detected using Western blotting.Results After model construc-tion,nerve cells and tissues in different regions of the rat brain were damaged.Spag6 expression,synaptic structure and function were altered.The activity of motor cilia in the third ventricle was disturbed and ischemic cerebral edema was observed.After up-regulation of Spag6 expression,cerebral edema was relieved and the activity of motor cilia was restored.Ischemic cerebral infarc-tion,nerve cell injury and synaptic structural abnormalities were reversed.The protein expression of Bcl-2,Survivin,GluN1,GluN2B,and GluA2 increased significantly(P＜0.01 or P＜0.05),while the expression of Bax decreased(P＜0.01).Conclusion Spag6 enhances synaptic function by restoring the active state of ventricular motor cilia,thereby alleviating ischemic brain edema mediated nerve damage.
