The close relationship between gastric cancer (GC) and type 2 diabetes mellitus (T2DM) has garnered significant attention. On one hand, T2DM may play a role in the development and progression of GC, correlating with poor patient outcomes. On the other hand, after radical surgery for GC, T2DM can be effectively managed, potentially improving tumor prognosis. In recent years, bariatric and metabolic surgery (BMS) has revolutionized T2DM treatment for obese and overweight patients. Comparative analyses reveal similarities between surgical approaches for gastric cancer and BMS, leading to the emergence of the onco-metabolic surgery (OMS) concept, which suggests that radical tumor resection and T2DM remission in GC patients can be potentially achieved through a single procedure. However, there are notable differences between OMS and BMS, including target populations, surgical details, and perioperative management. Therefore, optimizing the application of the OMS concept in GC patients holds significant clinical importance. This article provides a review to facilitate the better implementation of this concept in practice.

Objective To explore the age-related biological properties of bone-derived mesenchymal stem cells(BMSCs)from mice of different age groups and their osteogenic differentiation induced by bone morphogenetic protein 2(BMP2).Methods Eight C57BL/6J mice were divided into a young group(4 weeks old,weighing 10~15 g,n=4)and an old group(12 months old,weighing 20~25 g,n=4),with half male and half female.MSCs were extracted from the whole bones of the 2 groups of mice.After the obtained cells were identified with flow cytometry for the surface markers,β-galactosidase staining was employed to compare the senescence level of BMSCs,MTT and EdU incorporation assays were conducted to compare the proliferation and self-renewal abilities of between the 2 groups.Western blotting was employed to analyze the expression of CyclinD1 and P21 in BMSCs.Then ALP staining,Alizarin Red staining and RT-qPCR were used to evaluate the osteogenic differentiation ability of the cells.RNA sequencing was performed to compare the differential gene expression in BMP2-induced BMSCs.Lastly,the sequencing results were re-confirmed by using flow cytometry.Results Flow cytometry showed that the sorted and cultured mouse BMSCs met the criteria for MSCs.The results of β-galactosidase staining indicated that the senescence level of BMSCs in the old group was significantly higher than that in the young group(P<0.05).MTT and EdU doping experiments revealed that the cell viability and proliferation ability of BMSCs were significantly lower in the old group than the young group(P<0.05).Western blotting displayed that the expression level of cell cycle protein CyclinD1 was lower,whereas that of cell cycle inhibitory factor P21 was significantly higher in the BMSCs from the old group than the cells from the young group(P<0.05).ALP/Alizarin Red staining and RT-qPCR demonstrated that the BMSCs from the young group had stronger osteogenic differentiation capacity after BMP2 treatment when compared the cells of the old group(P<0.05).RNA sequencing results displayed that the changing profile of CD51 expression was in opposite trends in the young and old BMSCs after BMP2 treatment.Finally,flow cytometry revealed that the percentage of CD51+cells within the CD45-cells was significantly higher in the young group than the old group.Conclusion The decrease in the percentage of CD51+cells among CD45-cells in aged BMSCs is closely associated with their decreased responsiveness to BMP2-induced osteogenic differentiation.

Objective To investigate the effect of embryonic inflammatory exposure on the response of mouse offspring to interphotoreceptor retinoid-binding protein(IRBP)-induced experimental autoimmune uveitis(EAU).Methods RNA transcriptome sequencing data from eyeballs of C57BL/6J mouse offspring born to mothers with active EAU were used to screen immune-associated differentially expressed genes in the eyes of the exposed offspring.Gene fragments overlapping in the two datasets were screened using Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analyses to identify biological pathways associated with the gene fragments.Hub genes were identified from these intersecting genes by protein-protein interaction network analysis.EAU models of maternal uveitis were established by immunization with IRBP651-670,and expression levels of the pivotal genes in the offspring exposed to inflammation by maternal uveitis were examined by fluorescence quantitative polymerase chain reaction.EAU severity,T lymphocyte proliferation,and serum cytokines were detected to investigate the immune effect in offspring from mothers with an active inflammation response to IRBP induction.Results Microarray analysis identified 72 immune-related differentially expressed genes in exposed samples compared with the findings in control samples.These genes were mainly enriched in Toll-like receptor signaling,mitogen-activated protein kinase signaling,and B cell receptor signaling pathways.Protein-protein interaction network interaction analysis screened out four hub genes,Psmc5,Psmc3,Psmd4,and Psmd8,and mRNA levels of these four genes were increased in the adult offspring from mothers with active uveitis compared with the findings in healthy offspring.In addition,the group induced with 150 μg IRBP showed an increase in the severity of clinical and pathological outcomes in offspring with EAU affected by active inflammation,compared with the healthy offspring group(P=0.0087,P=0.0410).Meanwhile,T cell proliferation in the offspring was enhanced during the inflammatory activity stage and secretion of the inflammatory cytokines interleukin(IL)-17 and IL-6 was increased(P=0.0450,P=0.0300).Conclusions Psmc5,Psmc3,Psmd4,and Psmd8 may be important genes exacerbating uveitis in offspring of mothers with active uveitis,associated with increased T cell proliferation and production of IL-17 and IL-6.

Background:Despite the recent development of new therapies, multiple myeloma (MM) remains an incurable disease. Thus, new, effective treatments are urgently needed, particularly for relapsed or refractory MM (RRMM). In an earlier phase I study, a novel form of recombinant human Apo2L/tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) that is currently in clinical development for the treatment of hematologic malignancies, i.e., circularly permuted TRAIL (CPT), was well tolerated at a dose of 2.5mg/kg per day and showed promising preliminary activity in patients with RRMM. This phase II, open-label, multicenter study further investigated the effcacy and safety of 2.5-mg/kg per day CPT as single-agent therapy for patients with RRMM. Methods:Patients with RRMM were treated once daily with CPT (2.5mg/kg, intravenously) for 14 consecutive days for each 21-day cycle. Clinical response and toxicity were assessed after each treatment cycle. Results:Twenty-seven patients received CPT. Using the European Group for Blood and Marrow Transplantation criteria, we calculated the overall response rate of 33.3% with 1 near-complete response (nCR) and 8 partial responses (PRs). The clinical beneift rate (48.1%) included 1 nCR, 8 PRs, and 4 minimal responses. The most common treatment-related adverse events (TRAEs) were fever, aspartate aminotransferase elevation, alanine aminotransferase elevation, leucopenia, rash, neutropenia, and thrombocytopenia. We graded toxicity using the Common Toxicity Criteria for Adverse Events, version 3.0, and determined that 37.0% of patients had at least 1 grade 3–4 TRAE. Conclusions:CPT as a single agent can elicit a response in patients with RRMM and is well tolerated. Further clinical investigation is warranted.
