Objective To investigate the effects of Ras-related protein Rab-2B(RAB2B)on the biological behaviors of pancreatic cancer cells and elucidate its underlying mechanism.Methods PANC-1 cells,which exhibit relatively high RAB2B expression,and BXPC-3 cells,which display relatively low RAB2B expression,were selected from five pancreatic cancer cell lines.RAB2B-siRNA and pcDNA3.1-RAB2B plasmids were transfected into PANC-1 and BXPC-3 cells using a cell transfection technique.The CCK-8 assay was employed to evaluate the prolif-erative capacity of pancreatic cancer cells following RAB2B intervention.Wound healing and Transwell chamber assays were utilized to assess the migratory and invasive capabilities of pancreatic cancer cells.Additionally,the mRNA and protein expression levels of RAB2B,NF-κB,and Fibronectin 1(FN1)were analyzed by qRT-PCR and Western blot(WB),respectively.Results RAB2B mRNA and protein expression levels were significantly down-regulated in PANC-1 cells following transfection(P<0.05).CCK-8 assay results demonstrated that the proliferative capacity of PANC-1 cells was markedly reduced(P<0.05),and the wound-healing ability was substantially impaired(P<0.01)upon RAB2B knockdown.Transwell assays revealed a significant decrease in cell migration(P<0.01),while Western blot analysis indicated that the expression levels of phosphorylated p65 and FN1 were notably diminished(P<0.01).Conversely,overexpression of RAB2B reversed these aforementioned alterations.Conclusions Knockdown of RAB2B in PANC-1 cells significantly suppresses cell proliferation and migration,whereas overexpression of RAB2B in BXPC-3 cells markedly promotes these processes.This effect is likely mediated through the activation of the NF-κB signaling pathway and the subsequent regulation of FN1 expression.

Objective:To compare the clinical characteristics of severe Mycoplasma pneumoniae pneumonia（SMPP）with bronchiolitis and consolidation to raise awareness.Methods:Retrospective analysis was conducted on children hospitalized at the first affiliated hospital of Xiamen University diagnosed with（SMPP）from February 2023 to January 2024.The children were divided into bronchiolitis group and large consolidation group based on their high-resolution CT imaging findings.Data on basic information，clinical features，auxiliary examination results，and bronchoscopy findings were analyzed.Results:This study included 415 pediatric patients，including 203 with bronchiolitis and 212 with large consolidation.The proportion of males，atopy rate，and first-degree relative atopy rate in the bronchiolitis group were higher，and the age of the bronchiolitis group was younger（ P<0.05）.The fever peak，incidence of fever，and low breath sound in the bronchiolitis group were lower，and the incidence of hypoxemia，wheezing，shortness of breath，inspiratory tri-concave signs，moist rales were higher than those in the consolidation group（ P<0.05）.The white blood cell counts，platelet counts，and lactate dehydrogenase were higher and the percentage of neutrophils，C-reactive protein，ferritin，D-dimer，and fibrinogen degradation products were lower in the bronchiolitis group than those in the consolidation group（ P<0.05）.The rate of 2 or more bronchoscopy procedures，and the proportion of longitudinal plica，mucus plug，and plastic in the consolidation group were higher than those in the bronchiolitis group（ P<0.05）.After three months of follow-up，there were 8 cases of bronchiolitis obliterans，including 7 cases in the bronchiolitis group and 1 case in the large consolidation group. Conclusion:If atopy，wheezing，and dyspnea are present in young children and preschool children with confirmed SMPP，they should be closely monitored for signs of bronchiolitis SMPP.Children with significant consolidation on imaging should have the possibility of various intrapulmonary and extrapulmonary problems taken into account.Appropriate treatment options should be implemented during the acute phase based on the imaging findings.

Inflammatory response is a common feature of many acute and chronic diseases,which involves in activation of various cell types.Similar to tumor cells,inflammatory response is regulated by glucose metabolic reprogramming.Cells involved in pro-inflammatory response,such as M1 macrophages,Th1 and Th17 lymphocytes,must generate energy rapidly through glycolysis transformed by glucose metabolic reprogramming to promote inflammation,while cells involved in immune regulation and anti-inflam-matory response,such as regulatory T cells and M2 macrophages,preferentially use fatty acid oxidation and oxidative phosphorylation as a main source for energy production.This article systematically reviews the role of glucose metabolic reprogramming in different stages of inflammatory response,as well as the various molecular mechanisms of glucose metabolic reprogramming in inflammatory response,including activation or inhibition of signaling pathways,epigenetic regulation,post-transcriptional regulation and post-translational modification,which aims to provide a reference for exploring the specific regulatory mechanisms of glucose metabolic reprogramming on inflammatory response and the therapeutic targets of inflammatory-related diseases.
