文摘Ovarian cancer(OC),a highly lethal gynaecological malignancy,is often diagnosed at advanced stages,resulting in a poor prognosis.Sialylation,an important form of glycosylation,significantly contributes to the progression of various solid tumours,including OC.Aberrant sialylation promotes tumour progression and metastasis by altering the structure and function of glycoproteins.Although its role in several solid tumours is well documented,the role of abnormal sialylation in OC and its potential as a therapeutic target remain poorly understood.This review highlights sialylation as a key regulator of the progression,metastasis,and drug resistance of OC.A deeper understanding of altered sialylation can contribute to the identification of novel therapeutic strategies for OC.

文摘CD5-positive(CD5+)diffuse large B-cell lymphoma(DLBCL)represents a special subgroup of DLBCL with a more aggressive disease course and is more likely to develop into relapsed/refractory(r/r)DLBCL in response to immunochemotherapy.The incidence of CD5+DLBCL is 5%–10%among DLBCL patients1.
文摘This study aims to understand the current status of fear of disease progression(FoP)in patients with coronary heart disease(CHD)following percutaneous coronary intervention(PCI),and to explore the relationship between FoP levels,perceived control,and medical coping strategies in these patients.A total of 360 CHD patients who underwent PCI at Xijing Hospital in Shaanxi Province between June and November 2024 were selected using a convenience sampling method.Surveys included a general information questionnaire,the Fear of Progression Questionnaire-Short Form(FoP-Q-SF),the revised Control Attitudes Scale(CAS-R),and the Medical Coping Modes Questionnaire(MCMQ).Pearson correlation analysis was used to examine the relationships between disease perception,positive coping strategies,and FoP.A total of 360 patients completed the study.The average score for FoP in patients with CHD after PCI was 31.64±4.61.FoP was negatively correlated with perceived control(r=-0.106,P<0.01)and medical coping(r=-0.194,P<0.01).Multivariate regression analysis showed that the type of intervention,family history of CHD,smoking status,perceived control,and total medical coping score were significant factors influencing FoP(P<0.01).Enhancing perceived control and identifying positive coping strategies can improve FoP levels in patients with CHD after PCI.Therefore,clinicians should focus on perceived control and medical coping levels in patients and develop targeted interventions to alleviate negative emotions related to FoP.
文摘BACKGROUNDColorectal cancer(CRC)typically progresses from benign colorectal polyps,whichrepresent a precursor to malignancy.Identifying the factors influencing thisprogression is crucial for early intervention and prevention.Although genetic andenvironmental factors have been widely studied,the role of lifestyle factors suchas physical activity,diet,smoking,sleep,and stress remains underexplored,especially in patients with early stage CRC or polyps.Recent evidence suggeststhat lifestyle behaviors may influence cancer progression by modulating inflammatorypathways,metabolic health,and immune function.For instance,highlevels of physical activity are linked to a reduced risk of CRC development,whereas poor dietary habits,smoking,and inadequate sleep have all beenimplicated in increased cancer risk and progression.Moreover,early-stage CRCpatients,who are often asymptomatic or have minimal symptoms,may particularlybenefit from lifestyle modifications to slow disease progression andimprove overall prognosis.The gap in understanding the specific influence ofthese lifestyle factors on colorectal polyps and early stage cancer progressionunderscores the need for comprehensive studies.By assessing several modifiablelifestyle factors and their association with disease progression,clinicians canidentify practical intervention points.These interventions could ultimately reducethe need for more aggressive treatments and improve the long-term outcomes inaffected patients.AIMTo investigate the association between lifestyle factors and disease progression inpatients with colorectal polyps and early stage cancer.METHODSIn this observational study conducted from January 2022 to December 2023,werecruited 120 patients with colorectal polyps or early stage cancer from Jiangshan People's Hospital.Lifestyle factors,including physical activity,dietary patterns,smoking status,sleep quality,andstress levels,were assessed using validated questionnaires.Disease progression was evaluated using standardizedfollow-up colonoscopies and pathological examinations.Cox proportional hazards models were used to analyzethe association between lifestyle factors and disease progression after adjusting for potential confounders.RESULTSDuring the median follow-up of 18.4 months,42(35.0%)patients experienced disease progression.High levels ofphysical activity were associated with reduced progression risk[adjusted hazard ratio(HR)0.55,95%confidenceinterval(CI):0.38-0.80,P=0.002]compared to low activity levels.High adherence to a healthy dietary patternshowed similar protective effects(adjusted HR 0.62,95%CI:0.43-0.89,P=0.009).Current smoking(adjusted HR1.92,95%CI:1.35-2.73,P<0.001)and poor sleep quality(adjusted HR 1.38,95%CI:1.05-1.82,P=0.021)wereassociated with increased progression risk.The impact of lifestyle factors was particularly pronounced in patientsyounger than 60 years and those with multiple polyps at baseline.CONCLUSIONThis study demonstrated significant associations between lifestyle factors and disease progression in colorectalpolyps and early stage cancer.Physical activity,dietary patterns,smoking status,and sleep quality have emergedas key modifiable factors influencing disease progression.These findings support the integration of lifestyleassessments and modifications in the clinical management of patients with colorectal neoplasia.

文摘BACKGROUND Uncertainty in illness(UI)and fear of progression(FoP)are significant psycho-logical challenges for lung cancer patients.Coping styles and social support are critical mediators,influencing patients'ability to manage the emotional and psy-chological burden of UI and FoP.However,limited research has explored the chain mediation effect of these factors on the relationship between UI and FoP,particularly among Chinese lung cancer patients.Convenience sampling was used to recruit inpatients diagnosed with lung cancer at a tertiary hospital in Changde City between November and December 2023.A total of 320 participants completed the Mishel Uncertainty in Illness Scale,Simp-lified Coping Style Questionnaire,Mandarin Chinese Version of the Medical Outcomes Study Social Support Survey,and Fear of Progression Questionnaire-Short Form.The chain mediation analysis was performed using the PROCESS macro to examine the relationships between the variables.RESULTS The results revealed that UI had a significant direct effect on FoP(effect=0.224,95%CI:0.136-0.408).Additionally,three indirect pathways were identified:(1)Social support(effect=0.128,95%CI:0.045-0.153);(2)Coping style(effect=0.115,95%CI:0.048-0.157);and(3)Chain mediators involving social support and coping style(effect=0.072,95%CI:0.045-0.120).The total indirect effect of the three mediation paths is 31.5%.These results confirm that social support and coping style significantly mediate the relationship between UI and FoP.CONCLUSION Based on cross-sectional data and a chain mediation model,this study explored the mechanisms between UI,social support,coping style,and FOP.Patients with lung cancer have higher levels of FOP,and the results of this study revealed a correlation between these four factors.Social support and coping style partially mediated the effects of UI on FOP,and there was a chain-mediating effect between UI and FOP.Programs designed to strengthen social support networks should also incorporate training to develop adaptive coping strategies,ultimately reducing FOP and improving overall quality of life.

文摘Objective Glioma is a highly heterogeneous and malignant intracranial tumor that presents challenges for clinical treatment.ELMO domain containing 2(ELMOD2)is a GTPase-activating protein that regulates a range of cellular biological processes.However,its specific role and prognostic value in tumorigenesis are still unknown.This study aimed to assess the prognostic relevance and signaling function of ELMOD2 in gliomas.Methods The Chinese Glioma Genome Atlas(CGGA)and The Cancer Genome Atlas(TCGA)databases were utilized to conduct a comprehensive analysis of the expression profile of ELMOD2 in gliomas,elucidating its associations with clinicopathological parameters and patient prognosis.Single-cell analysis was performed to characterize ELMOD2 expression across distinct glioma cell subpopulations.Gene Ontology(GO),Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses,and Gene Set Variation Analysis(GSVA)were employed to evaluate the potential biological functions of ELMOD2 in gliomagenesis.Specific small interfering RNAs(siRNAs)were used to knock down ELMOD2 in the glioma cell lines U251 and A172 to assess their cellular behaviors and examine the levels of multiple key signaling molecules associated with the occurrence of gliomas.Results ELMOD2 was overexpressed in gliomas,and this upregulation was correlated with tumor grade,isocitrate dehydrogenase mutation,and 1p/19q codeletion status.Notably,ELMOD2 expression was elevated in classical and mesenchymal subtypes,and single-cell resolution analysis revealed predominant enrichment within malignant cells.Functionally,ELMOD2 regulated cell cycle progression,and its overexpression was related to independent adverse outcomes.In vitro experiments revealed that ELMOD2 was located in the cytoplasm and nucleoplasm.Furthermore,ELMOD2 knockdown reduced proliferation,migration,and invasion and increased apoptosis in U251 and A172 cell lines.Finally,ELMOD2 knockdown significantly decreased p-Erk1/2.Conclusions ELMOD2 expression in glioma is positively correlated with tumorigenesis and is a crucial independent prognostic marker.Thus,ELMOD2 is a promising biomarker and therapeutic target for glioma treatment.
