Ulcerative colitis （UC） is a common digestive disease characterized by recurrence and remission alternation，which seriously affects the life quality and physical and mental health of patients. The pathogenesis of UC is complex，and studies have shown that the occurrence and development of UC are closely related to the transduction of multiple signaling pathways. The current western medicine treatment has many problems，such as single action target，more adverse reactions，poor patient tolerance，and easy recurrence after stopping the medicine. Traditional Chinese medicine has the advantages such as multi-targets，multi-pathways， and fewer adverse reactions， elucidating that the action mechanism of traditional Chinese medicine in the treatment of UC is the focus of current research. Therefore， this paper conducted a systematic review on how traditional Chinese medicine exerts therapeutic effects by regulating the signaling pathways related to UC in recent years，and it was found that traditional Chinese medicine can regulate nuclear factor-κB （NF-κB），adenylate-activated protein kinase （AMPK）/mammalian target of rapamycin （mTOR），Janus tyrosine protein kinase （JAK）/signal transducer and activator of transcription （STAT），phosphatidylinositol 3-kinase （PI3K） /protein kinase B （Akt），NOD-like receptor thermoprotein structural domain-related protein 3 （NLRP3）/cysteine protease-1 （Caspase-1），nuclear respiratory factor 2 （Nrf2）/heme oxygenase-1 （HO-1）， and several other pathways，thereby inhibiting oxidative stress and cellular pyroptosis，regulating the Tregs/Th17 cellular balance， promoting autophagic response and M2-type macrophage polarization，restoring the diversity and abundance of intestinal flora，promoting the repair of intestinal mucosal barrier function，and alleviating the inflammatory damage of UC colonic tissues. The holistic concept and evidence-based treatment of traditional Chinese medicine were combined with the modern molecular mechanism research of traditional Chinese medicine， and the traditional Chinese medicine combinations with different mechanisms， following regulation， were formulated into compound formulas or pairs of medicines according to the pattern of evidence. It is expected to achieve better therapeutic efficacy and to provide ideas and references for the modification of classic compound formulae of traditional Chinese medicine in UC treatment and clinical translation.

Ulcerative colitis （UC）， a chronic relapsing inflammatory bowel disease， involves multifaceted pathological mechanisms such as intestinal barrier dysfunction， immune dysregulation， and oxidative stress. Current therapeutic strategies remain limited in efficacy and safety. In recent years， the adenosine monophosphate-activated protein kinase （AMPK） signaling pathway has emerged as a pivotal therapeutic target for UC due to its central role in energy metabolism， inflammatory regulation， and intestinal homeostasis. This article systematically reviewed the mechanisms by which traditional Chinese medicine （TCM） prevented and treated UC through the regulation of the AMPK signaling pathway， with a focus on elucidating AMPK's multidimensional regulatory network in inflammatory signaling crosstalk， alleviating oxidative stress， restoring intestinal immune balance， repairing the intestinal barrier， and modulating gut microbiota. Leveraging its unique advantages of multi-target engagement and low toxicity， TCM demonstrates promising potential in UC treatment and has become a focal area of research. By systematically summarizing and synthesizing the existing literature on TCM-mediated AMPK pathway modulation in UC， this review aims to provide a theoretical foundation for advancing mechanistic research and clinical interventions in UC.

Ulcerative colitis （UC） is a chronic and relapsing inflammatory bowel disease that primarily affects the mucosal layer of the rectum and colon. Its pathogenesis is complex and remains incompletely understood. Endoplasmic reticulum stress （ERS） plays a critical role in cellular responses to external stress and the maintenance of homeostasis， and its abnormal activation is closely associated with the development of various inflammatory diseases， particularly in the pathological process of UC. ERS maintains cellular homeostasis by activating the unfolded protein response （UPR）. However， when ERS is prolonged or excessive， UPR fails to alleviate the stress， leading to epithelial cell death and aggravating the progression of UC. Modulating ERS may serve as a key target for the prevention and treatment of UC， and it is one of the current research hotspots. Traditional Chinese medicine （TCM） has shown significant efficacy in regulating ERS， offering unique therapeutic advantages through multi-target and multi-pathway mechanisms. Recent studies have confirmed that TCM can alleviate ERS， inhibit apoptosis， regulate autophagy， reduce inflammatory responses， and maintain intestinal barrier function to prevent and treat UC. This review summarized the relationship between ERS and UC and discussed the intervention of TCM in regulating ERS for the treatment of UC， aiming to provide new insights and approaches for the treatment of UC with TCM.

Ulcerative colitis （UC）， a chronic， non-specific inflammatory bowel disease with typical symptoms such as abdominal pain， diarrhea， and bloody stools， demonstrates a high relapse rate and difficulty in curing. Sishenwan， first recorded in Internal Medicine Abstract （Nei Ke Zhai Yao）， are a classic prescription for treating diarrhea caused by deficiency of the spleen and kidney Yang. The core therapeutic principle of Sishenwan is warming and tonifying the spleen and kidney， and astringing the intestine and stopping diarrhea. In recent years， Sishenwan have demonstrated distinct advantages in the clinical treatment of UC. The pathogenesis of UC involves multiple factors， including immune dysregulation and gut microbiota imbalance. Although Western medicine is effective in the short term， its side effects， high relapse rate， and resistance associated with long-term use pose substantial challenges. Sishenwan have shown excellent clinical outcomes in the treatment of UC due to deficiency of the spleen and kidney Yang. Modern clinical studies indicate that Sishenwan， used alone or in combination with Western medicine or other Chinese medicine compound prescriptions， significantly improve the clinical efficacy in treating UC due to deficiency of the spleen and kidney Yang. Sishenwan effectively alleviate core symptoms such as mucus， pus， and blood in stools， and persistent abdominal pain， reduce Mayo scores and the relapse rate， and improve patients' quality of life. Research on the material basis reveals that Sishenwan contain multiple active ingredients such as psoralen， isopsoralen， and evodiamine. Mechanism studies indicate that Sishenwan inhibit the inflammatory cascade reactions by regulating the signal network through multiple targets. Sishenwan regulate cellular immunity and restore intestinal immune homeostasis. At the microecological level， Sishenwan promote the intestinal barrier repair through the "microbiota-metabolism-immunity" axis. The current research still needs to be deepened in aspects such as the mining of specific biomarkers for syndromes and the exploration of the collaborative mechanism of traditional Chinese and Western medicine. In the future， a full-chain system covering syndrome differentiation， targeting， and monitoring needs to be constructed for promoting the paradigm transformation of Sishenwan into precision drugs. This review systematically explains the treatment mechanism of Sishenwan regarding the combination of disease and syndrome and its multi-target regulatory characteristics， providing a theoretical basis and transformation direction for the treatment of UC with integrated traditional Chinese and Western medicine.

This study investigated the effect of small RNA ncBCG201 on the stress adaptation and intracellular survival of Myco-bacterium bovis.Differentially expressed ncRNAs were screened with RNA-seq after BCG infection of THP-1 macrophages.The ncBCG201 overexpression strain was constructed,and its stress survival,growth,biofilm formation,and intracellular survival were assessed.The ncBCG201 strain showed slower growth and earlier entry into stationary phase.Survival significantly increased under car-bon starvation but decreased under membrane pressure.Biofilm formation capability decreased.Intracellular survival in THP-1 macro-phages at 24 h and 48 h was significantly higher than observed in the control.Therefore,ncBCG204 enhances BCG survival within macrophages by modulating stress adaptability.

Objective To explore the value of Delta radiomics based on dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)in the early prediction of pathological complete response(pCR)after neoadjuvant chemotherapy(NAC)for breast cancer.Methods The MRI and clinical data of 107 patients with breast cancer and received NAC treatment were retrospectively collected.The patients were randomly divided into training set(74 cases)and test set(33 cases)in a ratio of 7︰3.The volume of interest(VOI)were marked,and the radiomics features(Pre-features,Post-features)were extracted from the peak images of DCE-MRI before NAC and after the second cycle of NAC.The Delta features were obtained by subtracting Post-features from Pre-features.Subsequently,six machine learning methods including random forest(RF),multi-layer perceptron(MLP),extreme gradient boosting(XGBoost),light gradient boosting machine(LightGBM),K-nearest neighbor(KNN)and logistic regression(LR)were used to consult the model,respectively.The receiver operating characteristic(ROC)curve was used to evaluate the model performance,and the machine learning method and radiomics feature set with the highest area under the curve(AUC)in the test set were selected for further analysis.Univariate and multivariate logistic regression analyses were performed to identify independent clinical predictors and the machine learning method with the best radiomics model was used to construct the clinical model.Combined with tumor radiomics features and independent clinical predictors,the best machine learning method was used to construct a combined model,and the performance of the model was evaluated.Results Progesterone receptor(PR)status was identified as an independent predictor of NAC efficacy in breast cancer.The model established using the RF machine learning method based on the Delta features had the highest AUC of 0.926 in the test set.The AUC of the combined model in the test set was 0.957,which was higher than that of the Pre-radiomics model,Post-radiomics model,Delta-radiomics model,and clinical-features model.Conclusion The combined model of Delta features and clinical features has a good performance in predicting pCR after NAC for breast cancer.
