文摘The comorbidity of skin and gastrointestinal tract(GIT)diseases,primarily driven by the gut-skin axis(GSA),is well established.However,the genetic contribution to the GSA remains unclear.Here,using genome-wide association study(GWAS)summary statistics from European populations,we performed a genome-wide pleiotropic analysis to investigate the shared genetic basis and causal associations between skin and GIT diseases.We observed extensive genetic correlations and overlaps between skin and GIT diseases.A total of 298 pleiotropic loci were identified,75 of which were colocalized,and 61 exhibited pleiotropic effects across multiple trait pairs,including 2p16.1(PUS10),6p21.32(HLA-DRB1),10q21.2(ZNF365),and 19q13.11(SLC7A10).Additionally,five novel loci were identified based on the pleiotropic analysis;among them,the 15q22.2 locus harboring RORA was validated by the latest inflammatory bowel disease GWAS.Gene-based analysis identified 394 unique pleiotropic genes,which were enriched in GSA-associated tissues and the immune system,and protein-protein interaction analysis further revealed that the GPCR-cAMP,chromatin remodeling,JAK-STAT,and HLA-mediated immunity pathways were involved in GSA comorbidity.Notably,the JAK-STAT pathway showed strong potential for drug repurposing,with adalimumab targeting tumor necrosis factor and ustekinumab targeting interleukin-12 subunit beta already being used to treat both skin and GIT diseases.Finally,Mendelian randomization analysis identified five significant causal associations,and subsequent mediation analysis identified three potential microbiota-GIT-skin pathways.Taken together,our study demonstrated that the shared genetic factors between skin and GIT diseases were widely distributed across the genome.These findings will enhance our understanding of the genetic mechanisms underlying GSA comorbidity.
文摘Berberine,an isoquinoline quaternary alkaloid,is a molecule with significant therapeutic adaptability.It has been identified,isolated,and measured in a wide range of plant families and species.Of these,Berberis stands out as a significant natural source of berberine,with Berberis vulgaris(B.vulgaris)bark being one of the most notable.The numerous health benefits associated with berberine include its potential use in the treatment of diseases,such as cancer,cardiovascular diseases,diabetes,and neurological disorders.The principal use of berberine has been for its antidiarrheal properties,which may have several modes of action.Its potent antioxidant and anti-inflammatory effects are responsible for its preventive action against stomach ulcers,and it has been found to kill dangerous gut bacteria while boosting the species and numbers of health-promoting bacteria.It protects the colon by influencing the production of several immune factors in addition to upregulating the Wnt-βcreatinine signaling cascade.Berberine has shown its potential in regulating cholesterol metabolism by elevating the levels of low-density lipoprotein receptor in the liver.This review comprehensively examines the pharmacokinetics,multifaceted bioactivities,and gutprotective roles of berberine,providing a detailed analysis of its diverse physiological functions and potential clinical applications to advance the understanding and management of gastrointestinal diseases.
文摘Experimental therapies targeting immune and stromal cells,such as mast cells,cancer-associated fibroblasts,dendritic cells,and tumor endothelial cells,in the treatment of gastrointestinal solid tumors pose new and complex surgical and medico-legal challenges.These innovative treatments require that informed consent not be limited to simple acceptance of the medical procedure,but instead reflect a true relational and cognitive process grounded in understanding,free choice,and the ability to revoke consent at any time.In particular,it is essential that the patient understands the experimental nature of the therapy,its development stage,potential benefits and risks,as well as the implications for their health and personal dignity.In the case of stromal cell-based treatments,which may exert complex immunomodulatory effects or activate angiogenic pathways that are not yet fully understood,patients must be made fully aware that they are participating in a non-standardized therapy whose outcomes,whether beneficial or harmful,cannot yet be predicted with certainty.This requires particularly careful medical communication,using simple yet scientifically accurate explanations delivered in appropriate language,along with a final verification of the patient’s actual understanding.
文摘BACKGROUND Gastrointestinal stromal tumors(GISTs)are rare mesenchymal neoplasms primarily originating in the stomach or small intestine.Duodenal GISTs are particularly uncommon,accounting for only a small fraction of GIST cases.These tumors often present with nonspecific symptoms,making early detection challenging.This case discusses a duodenal GIST misdiagnosed as pancreatic cancer due to obstructive jaundice.CASE SUMMARY A 40-year-old male with jaundice and abdominal symptoms underwent imaging,which suggested a malignant periampullary tumor.Preoperative misdiagnosis of pancreatic cancer was made,and surgery was performed.Postoperative histopathology confirmed a duodenal GIST.The role of artificial intelligence in the diagnostic pathway is explored,emphasizing its potential to differentiate between duodenal GISTs and other similar conditions using advanced imaging analysis.CONCLUSION Artificial intelligence in radiomic imaging holds significant promise in enhancing the diagnostic process for rare cancers like duodenal GISTs,ensuring timely and accurate treatment.

文摘Objective:To investigate the impact of targeted nursing interventions based on frailty prediction models on peri-hospitalization clinical outcomes in middle-aged and elderly patients with upper gastrointestinal bleeding(UGIB).Methods:A prospective cohort study was conducted,and 126 middle-aged and elderly patients with UGIB admitted from August 2024 to August 2025 were selected as the study subjects.The patients were divided into the intervention group(63 cases)and the control group(63 cases)based on whether they received nursing intervention based on frailty prediction models.The control group received routine care,while the intervention group,on the basis of routine care,used the FRAIL scale combined with laboratory indicators(albumin,hemoglobin,etc.)to establish a predictive model to evaluate patients within 24 hours of admission,and implemented multi-dimensional targeted nursing intervention for pre-frailty or frailty patients screened out.The incidence of frailty,rebleeding rate,average length of stay,hospitalization cost,and nursing satisfaction during hospitalization were compared between the two groups.Results:The incidence of frailty during hospitalization in the intervention group was 11.1%(7 cases/63 cases),significantly lower than 31.7%(20 cases/63 cases)in the control group,and the difference was statistically significant(p<0.05).The rebleeding rate of 4.8%vs 12.7%,the average length of stay of(7.2±1.5)days vs(9.1±2.2)days,and the average hospitalization cost of(23,000±6,000)yuan vs(28,000±7,000)yuan in the intervention group were all lower than those in the control group(all p<0.05).The nursing satisfaction score of the intervention group(93.5±4.2)points was higher than that of the control group(86.3±5.8)points(p<0.05).Conclusion:The frailty prediction model applied to the peri-hospitalization care of middle-aged and elderly patients with UGIB can effectively identify frailty risk.Through early targeted intervention,the incidence of frailty and rebleeding rate can be reduced,the length of hospital stay can be shortened,medical expenses can be reduced,and nursing satisfaction can be improved,which has clinical promotion value.
文摘BACKGROUND Gastrointestinal endoscopy technology has significantly improved the diagnostic accuracy and the successful treatment of gastrointestinal diseases.However,a series of ethical issues have emerged,such as expanding treatment indications,which affect the fair distribution of medical resources.There is limited research on ethical issues in the field of digestive endoscopy.AIM To investigate the level of ethical awareness among gastrointestinal endoscopy practitioners and analyze the ethical issues involved in gastrointestinal endoscopy technology.METHODS A questionnaire survey was performed to collect relevant data(gender,age,degree of education,professional title,personnel category,the level of understanding medical ethical principles,ethics training and its learning pathways)from gastrointestinal endoscopy practitioners at the Second Hospital of Dalian Medical University and Dalian Friendship Hospital,including licensed physicians and nurses(including trainees and graduate students).RESULTS The majority of gastrointestinal endoscopy practitioners have received training on ethics,but there is still considerable room for improvement in their ethical awareness.Different learning pathways may affect the mastery of ethical principles, and understanding of ethical principles is more easily achieved through hospital ethics institutions.CONCLUSIONTo address the ethical issues in gastrointestinal endoscopy technology, it is necessary to enhance the humanisticeducation of gastrointestinal endoscopy practitioners, incorporate ethical standards into the technology assessmentprocess, and establish a patient-centered diagnostic and treatment model to improve the ethical awareness of practitionersand achieve a balance between technology and ethics.

文摘Gastrointestinal tumors require personalized treatment strategies due to their heterogeneity and complexity.Multimodal artificial intelligence(AI)addresses this challenge by integrating diverse data sources-including computed tomography(CT),magnetic resonance imaging(MRI),endoscopic imaging,and genomic profiles-to enable intelligent decision-making for individualized therapy.This approach leverages AI algorithms to fuse imaging,endoscopic,and omics data,facilitating comprehensive characterization of tumor biology,prediction of treatment response,and optimization of therapeutic strategies.By combining CT and MRI for structural assessment,endoscopic data for real-time visual inspection,and genomic information for molecular profiling,multimodal AI enhances the accuracy of patient stratification and treatment personalization.The clinical implementation of this technology demonstrates potential for improving patient outcomes,advancing precision oncology,and supporting individualized care in gastrointestinal cancers.Ultimately,multimodal AI serves as a transformative tool in oncology,bridging data integration with clinical application to effectively tailor therapies.
文摘Gastrointestinal(GI)cancers remain a leading cause of cancer-related morbidity and mortality worldwide.Artificial intelligence(AI),particularly machine learning and deep learning(DL),has shown promise in enhancing cancer detection,diagnosis,and prognostication.A narrative review of literature published from January 2015 to march 2025 was conducted using PubMed,Web of Science,and Scopus.Search terms included"gastrointestinal cancer","artificial intelligence","machine learning","deep learning","radiomics","multimodal detection"and"predictive modeling".Studies were included if they focused on clinically relevant AI applications in GI oncology.AI algorithms for GI cancer detection have achieved high performance across imaging modalities,with endoscopic DL systems reporting accuracies of 85%-97%for polyp detection and segmentation.Radiomics-based models have predicted molecular biomarkers such as programmed cell death ligand 2 expression with area under the curves up to 0.92.Large language models applied to radiology reports demonstrated diagnostic accuracy comparable to junior radiologists(78.9%vs 80.0%),though without incremental value when combined with human interpretation.Multimodal AI approaches integrating imaging,pathology,and clinical data show emerging potential for precision oncology.AI in GI oncology has reached clinically relevant accuracy levels in multiple diagnostic tasks,with multimodal approaches and predictive biomarker modeling offering new opportunities for personalized care.However,broader validation,integration into clinical workflows,and attention to ethical,legal,and social implications remain critical for widespread adoption.

文摘BACKGROUND Gastrointestinal(GI)tumors are among the most prevalent malignancies,and surgical intervention remains a primary treatment modality.However,the complexity of GI surgery often leads to prolonged recovery and high postoperative complication rates,which threaten patient safety and functional outcomes.Enhanced recovery after surgery(ERAS)principles have been shown to improve perioperative outcomes through evidence-based,multidisciplinary care pathways.Despite its widespread adoption,there is a paucity of research focusing specifically on optimizing ERAS-guided nursing processes in the post-anesthesia care unit(PACU)and evaluating its impact on perioperative safety in patients undergoing GI tumor surgery.This study aimed to investigate whether an ERASbased PACU nursing protocol could enhance recovery,reduce complications,and improve patient safety in this surgical population.AIM To explore the impact of optimizing the recovery room nursing process based on ERAS on the perioperative safety of patients with GI tumors.METHODS A total of 260 patients with GI tumors who underwent elective surgeries under general anesthesia in our hospital from August 2023 to August 2025 and were then observed in the recovery unit(PACU)were selected.They were randomly divided into the observation group(the PACU nursing process was optimized based on ERAS)and the control group(the conventional PACU nursing process was adopted)by the random number grouping method,with 130 cases in each group.The time of gastric tube removal,urinary catheter removal,defecation time,hospital stay,time of leaving the room after tube removal,retention time in the recovery room,occurrence of complications,satisfaction and readmission rate were compared between the two groups after entering the room.Compare the occurrence of adverse events in the PACU nursing process between the two groups.RESULTS The time of gastric tube removal,urinary catheter removal,defecation time,hospital stay,retention time in the recovery room,total incidence of complications and readmission rate in the observation group were significantly lower than those in the control group,and the satisfaction rate was higher than that in the control group(P<0.05).The occurrence of adverse events in the PACU nursing process in the observation group was lower than that in the control group(P<0.05).CONCLUSION Optimizing the PACU nursing process based on ERAS can effectively accelerate the recovery process of patients undergoing GI tumor surgery,reduce adverse events,improve nursing satisfaction,and at the same time,lower the incidence of adverse events in the PACU nursing process,providing a more refined management basis for clinical practice.
文摘Objective:Deep learning is employed increasingly in Gastroenterology(GI)endoscopy computer-aided diagnostics for polyp segmentation and multi-class disease detection.In the real world,implementation requires high accuracy,therapeutically relevant explanations,strong calibration,domain generalization,and efficiency.Current Convolutional Neural Network(CNN)and transformer models compromise border precision and global context,generate attention maps that fail to align with expert reasoning,deteriorate during cross-center changes,and exhibit inadequate calibration,hence diminishing clinical trust.Methods:HMA-DER is a hierarchical multi-attention architecture that uses dilation-enhanced residual blocks and an explainability-aware Cognitive Alignment Score(CAS)regularizer to directly align attribution maps with reasoning signals from experts.The framework has additions that make it more resilient and a way to test for accuracy,macro-averaged F1 score,Area Under the Receiver Operating Characteristic Curve(AUROC),calibration(Expected Calibration Error(ECE),Brier Score),explainability(CAS,insertion/deletion AUC),cross-dataset transfer,and throughput.Results:HMA-DER gets Dice Similarity Coefficient scores of 89.5%and 86.0%on Kvasir-SEG and CVC-ClinicDB,beating the strongest baseline by+1.9 and+1.7 points.It gets 86.4%and 85.3%macro-F1 and 94.0%and 93.4%AUROC on HyperKvasir and GastroVision,which is better than the baseline by+1.4/+1.6macro-F1 and+1.2/+1.1AUROC.Ablation study shows that hierarchical attention gives the highest(+3.0),followed by CAS regularization(+2–3),dilatation(+1.5–2.0),and residual connections(+2–3).Cross-dataset validation demonstrates competitive zero-shot transfer(e.g.,KS→CVC Dice 82.7%),whereas multi-dataset training diminishes the domain gap,yielding an 88.1%primary-metric average.HMA-DER’s mixed-precision inference can handle 155 pictures per second,which helps with calibration.Conclusion:HMA-DER strikes a compromise between accuracy,explainability,robustness,and efficiency for the use of reliable GI computer-aided diagnosis in real-world clinical settings.
文摘BACKGROUND Early screening,preoperative staging,and diagnosis of lymph node metastasis are crucial for improving the prognosis of gastric cancer(GC).AIM To evaluate the diagnostic value of combined multidetector computed tomography(MDCT)and gastrointestinal endoscopy for GC screening,preoperative staging,and lymph node metastasis detection,thereby providing a reference for clinical diagnosis and treatment.METHODS In this retrospective study clinical and imaging data of 134 patients with suspected GC who were admitted between January 2023 and October 2024 were initially reviewed.According to the inclusion and exclusion criteria,102 patients were finally enrolled in the analysis.All enrolled patients had undergone both MDCT and gastrointestinal endoscopy examinations prior to surgical intervention.Preoperative clinical staging and lymph node metastasis findings were compared with pathological results.RESULTS The combined use of MDCT and gastrointestinal endoscopy demonstrated a sensitivity of 98.53%,specificity of 97.06%,accuracy of 98.04%,positive predictive value of 98.53%,and negative predictive value of 97.06%for diagnosing GC.These factors were all significantly higher than those of MDCT or endoscopy alone(P<0.05).The accuracy rates of the combined approach for detecting clinical T and N stages were 97.06%and 92.65%,respectively,outperforming MDCT alone(86.76% and 79.41%)and endoscopy alone(85.29% and 70.59%)(P<0.05).Among 68 patients with confirmed GC,50(73.53%)were pathologically diagnosed with lymph node metastasis.The accuracy for detecting lymph node metastasis was 66.00%with endoscopy,76.00%with MDCT,and 92.00% with the combined approach,all with statistically significant differences(P<0.05).CONCLUSION The combined application of MDCT and gastrointestinal endoscopy enhanced diagnostic accuracy for GC,provided greater consistency in preoperative staging,and improved the detection of lymph node metastasis,thereby demonstrating significant clinical utility.

文摘This editorial discusses Wang et al's article on familial gastrointestinal stromal tumors(GISTs).We read with great interest this article concerning the diagnosis,treatment,and post-treatment management of patients with familial GISTs.The actual incidence of GISTs may be underestimated due to diagnostic limitations and the long-term low-risk behavior of some GISTs.The molecular landscape of GISTs is primarily driven by mutations in the KIT and platelet-derived growth factor receptor alpha(PDGFRA)genes.A subset of GISTs without these mutations known as wild-type GISTs,may harbor other rare mutations,impacting their response to targeted therapies.Clinically,patients with GISTs present with nonspecific symptoms,often leading to delayed diagnosis.Genetic predispositions in familial GISTs provide insights into the genetic architecture and extragastrointestinal manifestations of GISTs.Management has evolved from surgical interventions to molecular-based therapies using tyrosine kinase inhibitors.The management of GISTs,especially in familial cases,requires a multidisciplinary approach.Cases of different gene mutations were reported in the same family,suggesting that incorporating genetic testing into routine clinical practice is crucial for the early identification of high-risk individuals and the implementation of tailored surveillance programs.
文摘Recent research has increasingly highlighted the potential oncogenic effects of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection within the gastrointestinal tract.Growing evidence suggests that SARS-CoV-2 may contribute to the development of gastrointestinal malignancies through several mechanisms,including sustained chronic inflammation,disruption of normal cellular homeostasis,and potential viral integration into host cells.These pathological processes have the potential to dysregulate critical cellular pathways,thereby promoting cancer development in vulnerable populations.A thorough understanding of how SARS-CoV-2 interacts with the development of gastro-intestinal cancer is essential for optimizing patient care and establishing compre-hensive,long-term monitoring protocols.This review highlighted the pressing need for ongoing research into the complex relationship between SARS-CoV-2 infection and the risk of gastrointestinal cancer.

文摘Objective To evaluate the clinical efficacy of Traditional Chinese Medicine(TCM)hot-pack therapy in treating postoperative gastrointestinal dysfunction in patients undergoing surgery for gastrointestinal malignancies.Method 60 postoperative patients with gastrointestinal malignancies were randomized into a treatment group(n=30)and a control group(n=30).Both groups received standard postoperative supportive care,including oral mosapride citrate(5 mg,three times daily,starting 6 h post-op,for 3 days).The treatment group additionally received external abdominal application of a TCM hot-pack twice daily(20-30 min each)for 3 days.Primary endpoints were time to first flatus,first defecation,and first oral intake.Secondary endpoints included numeric scores for abdominal pain and distension at 24 h and 72 h post-op,and overall clinical efficacy.Result Compared with controls,the treatment group showed significantly faster recovery:time to first flatus(50.3±7.8 h vs.62.5±9.4 h),first defecation(72.1±11.3 h vs.85.2±13.6 h),and first oral intake(48.0±9.5 h vs.62.5±12.4 h)(all P<0.01).At 24 h and 72 h,the treatment group reported lower abdominal pain and distension scores(24 h pain 5.1±1.3 vs.6.0±1.4,distension 2.3±0.5 vs.2.8±0.6;72 h pain 3.9±0.8 vs.4.7±0.9,distension 1.9±0.5 vs.2.3±0.6;P<0.05 to P<0.01).Total effective rate was higher in the treatment group(96.7%vs.90.0%,χ^(2)=6.96,P=0.031).Conclusion TCM hot-pack therapy combined with routine care significantly accelerates recovery of gastrointestinal function,shortens duration of postoperative dysfunction,and alleviates abdominal pain and distension in patients after gastrointestinal malignancy surgery,demonstrating notable clinical benefit.
文摘Gastrointestinal(GI)cancers,which predominantly manifest in the stomach,colorectum,liver,esophagus,and pancreas,accounting for approximately 35%of global cancer-related mortality.The advent of liquid biopsy has introduced a pivotal diagnostic modality for the early identification of premalignant GI lesions and incipient cancers.This non-invasive technique not only facilitates prompt therapeutic intervention,but also serves as a critical adjunct in prognosticating the likelihood of tumor recurrence.The wealth of circulating exosomes present in body fluids is often enriched with proteins,lipids,microRNAs,and other RNAs derived from tumor cells.These specific cargo components are reflective of processes involved in GI tumorigenesis,tumor progression,and response to treatment.As such,they represent a group of promising biomarkers for aiding in the diagnosis of GI cancer.In this review,we delivered an exhaustive overview of the composition of exosomes and the pathways for cargo sorting within these vesicles.We laid out some of the clinical evidence that supported the utilization of exosomes as diagnostic biomarkers for GI cancers and discussed their potential for clinical application.Furthermore,we addressed the challenges encountered when harnessing exosomes as diagnostic and predictive instruments in the realm of GI cancers.
文摘BACKGROUND The relationship between exercise and gastrointestinal(GI)health is complex and bidirectional.While moderate exercise generally promotes gut health by enhancing motility,reducing inflammation,and supporting microbial balance,intense or prolonged physical activity may exacerbate GI symptoms,particularly in individuals with preexisting digestive disorders.A deeper understanding of this interplay is essential for optimizing both exercise performance and GI well-being.AIM To synthesize current evidence on exercise-related GI disorders,exploring the prevalence,mechanisms,risk factors,and management strategies associated with exercise-induced GI symptoms.METHODS Following PRISMA guidelines,comprehensive searches of databases,including PubMed,Scopus,Web of Science,and EMBASE were conducted.Studies were included if they focused on exercise-induced GI disorders,encompassed randomized controlled trials,cohort studies,case-control studies,and cross-sectional designs,and addressed symptoms across various exercise modalities.Data were extracted and analyzed to identify patterns and implications for clinical and athletic practice.RESULTS A total of 231 studies met the inclusion criteria,highlighting both the benefits and risks of exercise on GI health.Regular moderate-intensity exercise,including activities such as walking,cycling,and yoga has been associated with improved GI function in conditions like gastroesophageal reflux disease,irritable bowel syndrome,inflammatory bowel disease,and constipation.These benefits are attributed to enhanced intestinal motility,reduced systemic inflammation,and improved gut barrier integrity.Additionally,exercise plays a role in regulating the gut-brain axis,with practices like yoga and Tai Chi demonstrating particular effectiveness in alleviating functional GI disorders.Conversely,high-intensity or prolonged exercise may contribute to symptoms such as nausea,diarrhea,and abdominal pain due to mechanisms like splanchnic hypoperfusion and increased intestinal permeability.Individual factors,including fitness level,dietary habits,hydration status,and underlying GI conditions,significantly influence the body’s response to exercise.CONCLUSION Moderate-intensity exercise is a beneficial and well-tolerated intervention for promoting GI health,whereas highintensity activities require careful monitoring,particularly in individuals with pre-existing GI disorders.Personalized exercise and dietary strategies are essential for balancing the benefits of physical activity with the risk of GI distress.Further research is needed to explore the long-term effects of exercise on gut microbiota composition and overall digestive health.
文摘Gastrointestinal stromal tumor(GIST)is a rare but an important clinical entity seen in our clinical practice.It is the most common mesenchymal tumor of the gastrointestinal tract and most common malignancy of the small intestine.Although the exact prevalence of GIST is not known,the incidence of GIST has been increasing.GISTs arise from interstitial cells of Cajal.Most of the GISTs occur due to mutation in c-kit gene or platelet derived growth factor receptor alpha gene.15%of GISTs do not have these mutations and they are called wildtype GISTs.Almost all GISTs express KIT receptor tyrosine kinase.Histologically,GISTs look like spindle cell tumors most of the time but they can be epitheloid or mixed type.The median size of GISTs varies from 2.7 cm to 8.9 cm.Clinically,patients with small GISTs remain asymptomatic but as the GIST size increases,patients present with various symptoms depending on the location of the GIST.Most of GISTs are located in the stomach or small bowel.Diagnosis is suspected on imaging and endoscopic studies,and confirmed by tissue acquisition with immunohistochemical staining.The aggressiveness of GISTs depends on the size,mitotic index and location.Surgical resection is the treatment of choice.But various endoscopic modalities of resection are increasingly being tried.Tyrosine kinase inhibitors are extremely useful in the management of large GISTs,unresectable GISTs and metastatic GISTs.Treatment options for metastatic GISTs also include radiotherapy,chemotherapy,hepatic artery embolization,chemoembolization and radiofrequency ablation.
