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Background:Bone tumors represent a significant clinical challenge characterized by high morbidity and complex therapeutic requirements.Although Astragali Radix(Huangqi)is recognized for its potential pharmacological benefits in cancer therapy,the specific molecular mechanisms and their influence on vitamin metabolism pathways in bone malignancies are not well defined.Methods:We conducted an integrated analysis of prognostic genes and survival outcomes in osteosarcoma,focusing on the expression of GPC2 and its correlation with tumor progression and patient survival rates.In order to explore the therapeutic relevance of 20 bioactive compounds extracted from Huangqi,molecular docking was performed to quantify their binding free energies to the GPC2 receptor,shedding light on their potential affinity and biological activity.Furthermore,the expression levels of GPC2 in tumor cells compared to normal cells were analyzed using qRT-PCR.Additionally,the effects of GPC2 overexpression and silencing on cellular viability,apoptotic response,and migratory capacity were systematically investigated.Results:In our study,GPC2 emerged as a significant prognostic gene,where high expression levels correlated with reduced overall survival.The molecular interactions between Astragalus components and the GPC2 receptor reveal compounds with strong affinity,suggesting their potential as effective targets.Furthermore,the overexpression of GPC2 enhanced tumor cell viability and migration,while its knockdown resulted in decreased cell viability and expanded apoptosis.Conclusion:This study demonstrates that Huangqi-derived components may exert anticancer effects by regulating the expression of the GPC2 gene within the vitamin metabolism pathway.These findings offer new insights into the therapeutic potential of traditional herbal medicine for improving bone tumor prognosis and provide a scientific foundation for future translational research.

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Objectives:The mechanism by which specific tumor subsets in colorectal cancer(CRC)use alternative metabolic pathways,particularly those modulated by hypoxia and fructose,to alter the tumor microenvironment(TME)remains unclear.This study aimed to identify these malignant subpopulations and characterize their intercellular signaling networks and spatial organization through an integrative multi-omics approach.Methods:Leveraging bulk datasets,single-cell RNA sequencing,and integrative spatial transcriptomics,we developed a prognostic model based on hypoxia-and fructose metabolism-related genes(HFGs)to delineate tumor cell subpopulations and their intercellular signaling networks.Results:We identified a specific subset of stanniocalcin-2 positive(STC2+)malignant cells spatially enriched within tumor regions and strongly associated with poor prognosis.This subset served as a key signaling hub in the TME,exhibiting increased epithelial–mesenchymal transition activity.STC2+cells engage in two spatially organized ligand–receptor interactions:the growth differentiation factor 15(GDF15)—transforming growth factor beta receptor 2(TGFBR2)pathway targeting endothelial cells and the migration inhibitory factor(MIF)—(cluster of differentiation 74[CD74]+C-X-C motif chemokine receptor 4[CXCR4])pathway targeting macrophages.Conclusion:This study identified a malignant cell state in CRC that is metabolically defined and spatially limited,including liver metastases,and is characterized by elevated STC2 expression and active immune-stromal interactions.Given the interplay between metabolic reprogramming and TME remodeling,STC2+malignant cells are a functionally significant subpopulation and a potential therapeutic target.

文摘Brain tumors require precise segmentation for diagnosis and treatment plans due to their complex morphology and heterogeneous characteristics.While MRI-based automatic brain tumor segmentation technology reduces the burden on medical staff and provides quantitative information,existing methodologies and recent models still struggle to accurately capture and classify the fine boundaries and diverse morphologies of tumors.In order to address these challenges and maximize the performance of brain tumor segmentation,this research introduces a novel SwinUNETR-based model by integrating a new decoder block,the Hierarchical Channel-wise Attention Decoder(HCAD),into a powerful SwinUNETR encoder.The HCAD decoder block utilizes hierarchical features and channelspecific attention mechanisms to further fuse information at different scales transmitted from the encoder and preserve spatial details throughout the reconstruction phase.Rigorous evaluations on the recent BraTS GLI datasets demonstrate that the proposed SwinHCAD model achieved superior and improved segmentation accuracy on both the Dice score and HD95 metrics across all tumor subregions(WT,TC,and ET)compared to baseline models.In particular,the rationale and contribution of the model design were clarified through ablation studies to verify the effectiveness of the proposed HCAD decoder block.The results of this study are expected to greatly contribute to enhancing the efficiency of clinical diagnosis and treatment planning by increasing the precision of automated brain tumor segmentation.

文摘Elevated lactate levels in solid tumors contribute to immunosuppression,metabolic reprogramming,and resistance to therapy.Although lactate oxidase(LOX)offers a viable strategy for in situ lactate depletion,its therapeutic efficacy is fundamentally limited by tumor hypoxia due to the oxygen dependence of LOX.Here,we report a hybrid nanomaterial-microbial system that enables hypoxiaresistant lactate catabolism through near-infrared(NIR)-IIb-triggered upconverson photosynthesis.This system integrates LOX-producing Escherichia coli(E.coli)with Chlorella(Chl)and lanthanide-doped upconversion nanoparticles(UCNPs),which convert deeply penetrating 1550 nm light into visible emission to drive oxygenic photosynthesis.Unlike conventional photosynthetic oxygenation approaches limited by shallow visible light penetration,this system enables spatiotemporally controlled oxygen generation deep within tumors,sustaining LOX activity under hypoxia.In murine tumor models,the hybrid symbionts significantly inhibited tumor growth,promoted T cell infiltration,and induced durable immune memory.This work establishes a versatile optogeneticmetabolic platform for overcoming oxygen-limited metabolism in cancer therapy via deep-tissue-activatable microbial photosynthesis.

文摘BACKGROUND Urinary system tumors often cause negative psychological symptoms,such as depression and dysphoria which significantly impact immune function and indirectly affect cancer prognosis.While epirubicin(EPI)is recommended by the European Association of Urology and can improve prognosis,its long-term use can cause toxic side effects,reduce treatment compliance,and increase psycho-logical burden.Therefore,an appropriate intervention mode is necessary.METHODS This was a retrospective study including 110 patients with urinary system tumors and depression admitted to Zhumadian Central Hospital between March 2021 and July 2023.Patients were divided into conventional(n=55)and joint inter-vention(n=55)groups.The conventional group received mitomycin and routine nursing,while the joint intervention group received EPI and mindfulness intervention.Both groups underwent three cycles of chemotherapy.Immune function(CD4+cells,CD8+cells,CD4+/CD8+ratio),tumor marker levels[urinary bladder cancer antigen(UBC),bladder tumor antigen(BTA)and nuclear matrix protein 22(NMP22)],quality of life questionnaire-core 30(QLQ-C30),17-item Hamilton depression scale(HAMD-17),and cancer-related fatigue[cancer fatigue scale(CFS)]were assessed.Adverse reactions and nursing satisfaction were recorded and evaluated.RESULTS Post-intervention,CD4+,CD8+,and CD4+/CD8+levels increased in both groups,with the joint intervention group showing more significant improvement(P<0.05).Tumor marker levels(NMP22,BTA,and UBC)were lower in the joint intervention group compared to the conventional group(P<0.05).The joint intervention group also showed a greater reduction in HAMD-17 scores(9.38±3.12 vs 15.45±4.86,P<0.05),higher QLQ-C30 scores,and lower CFS scores(both P<0.05).Additionally,the joint intervention group had a lower incidence of adverse reactions and higher nursing satisfaction(P<0.05).CONCLUSION EPI combined with mindfulness intervention significantly improved clinical outcomes in patients with urinary system tumors and depression and is worthy of clinical application.
