Objective:To evaluate the effectiveness of splenic circulation control technology in minimally invasive radical resection surgery for pancreatic neck/body cancer.Methods:This is a retrospective case series study. Retrospective analysis of clinical data of 12 patients who underwent laparoscopic or robotic radical resection for pancreatic neck/body cancer at the Department of Gastrointestinal and Pancreatic Surgery,Zhejiang Provincial People′s Hospital between January 2024 and January 2025. There were 7 males and 5 females,with mean age of 68 years (range: 52 to 79 years). Clinical data including preoperative,intra-operative and postoperative outcomes were analyzed. Postoperative follow-up was conducted via outpatient visits and telephone interviews,with the follow-up ending on April 1,2025.Results:All 12 patients underwent minimally invasive radical resection of pancreatic neck/body cancer using splenic circulation control technology,consisted of 3 laparoscopic and 9 robotic procedures. The mean operative time was 185 minutes (range: 140 to 315 minutes),and the average blood loss was 100 ml (range: 30 to 300 ml). Two cases involved combined organ resection.There was no conversion to open surgery. Postoperative complications were observed in 2 patients. One patient developed grade B pancreatic leakage,managed by ultrasound-guided puncture.The patient was discharged with drainage tube. The other patient experienced chylous leakage,recovered with conservative treatment. No delayed gastric emptying,hemorrhage or reoperations were observed. The median postoperative hospital stay was 13 days (range: 8 to 20 days).Conclusion:The splenic circulation control technique is simple and safe,and shows certain application prospects in minimally invasive radical resection of pancreatic neck and body cancer.

Objective:To investigate the effects of human glycolipid transfer protein(GLTP)on proliferation,migration and invasion of pancreatic cancer(PC)cells,and to elucidate their mechanisms.Methods:The difference in the expression levels of GLTP proteins between PC tissue and normal pancreas tissue was analyzed by University of Alabama at Birmingham Cancer Data Analysis Platform(UALCAN)Database,as well as the difference in the expression levels of GLTP protein between PC tissue and normal pancreas tissue of the PC patients with different clinicopathological characteristics.The PANC-1 cells were cultured in vitro and divided into control group(transfected with pFLAG-CMV4 plasmid)and GLTP-overexpression(GLTP-OE)group(transfected with pFLAG-GLTP plasmid).The stably GLTP transfected cells were established using the antibiotic screening method.Knock-down experiments were performed using non-specific siRNA transfected PANC-1 cells as control group and si-GLTP transfected PANC-1 cells as si-GLTP group.Western blotting method was used to detect the expression of GLTP protein in the cells in various groups,cell counting kit-8(CCK-8)method was used to detect the proliferation activities of PANC-1 cells,clone formation assay was used to detect the number of clone formation,and Transwell chamber assay were used to detect the numbers of migration and invasion cells in various groups.Transcriptomics sequencing analyses were conducted to assess the possible mechanism of GLTP in the PANC-1 cells.Western blotting method was employed to detect the expression levels of phosphatidylinositol 3-kinase(PI3K),phosphorylated PI3K(p-PI3K),protein kinase B(Akt),and phosphorylated Akt(p-Akt)proteins in the PANC-1 cells in various groups;Real-time fluorescence quantitative PCR(RT-qPCR)was used to assess the expression levels of amphiregulin(AREG)and kinase insertion domain receptor(KDR)mRNA in the cells in various groups.The mice were randomly divided into control group(injected with pFLAG-GMV4 transfected PANC-1 cells)and experimental group(injected with pFLAG-GLTP stably transfected PANC-1 cells),and the subcutaneously transplanted tumor models were prepared;the volumes and weights of the transplanted tumors of the mice in two groups were measured.Results:UALCAN database analysis showed that the expression level of GLTP protein in PC tissue was lower than that in normal pancreas tissue(P＜0.01),and there were statistically significant differences in the GLTP protein expression between PC tissue and normal pancreas tissue of the PC patients with different cancer stages(P＜0.05),tumor grades(P＜0.05),ages(P＜0.001),and genders(P＜0.05).Compared with control group,the proliferation activity(P＜0.01)and the number of clone formation(P＜0.001)of the cells in GLTP-OE group were decreased,while the numbers of migration cells(P＜0.001)and invasion cells(P＜0.01)were decreased.In the knock-down experiment,compared with control group,the proliferation activity(P＜0.01)and the number of clone formation(P＜0.05)of the cells in GLTP-OE group were increased,while the numbers of migration cells(P＜0.001)and invasion cells(P＜0.001)were increased.Compared with control group,the tumor weight and volume of the mice in experimental group were decreased(P＜0.01),following the injection of tumor cells for a period of four weeks.In the over-expression experiment,compared with control group,the expression levels of p-PI3K(P＜0.01),p-Akt-S473(P＜0.01),and p-Akt-T308(P＜0.05)proteins in the cells in GLTP-OE group were decreased;the expression levels of AREG(P＜0.01)and KDR(P＜0.01)mRNA were decreased.In the knock-down experiment,compared with control group,the expression levels of p-PI3K(P＜0.01),p-Akt-S473(P＜0.01),and p-Akt-T308(P＜0.01)in the cells in si-GLPT group were increased,and the expression levels of AREG(P＜0.01)and KDR(P＜0.05)mRNA were increased.Conclusion:Low expression levels of GLTP in PC tissue are present.The over-expression of GLTP can inhibit the proliferation,migration and invasion of PANC-1 cells,as well as the growth of subcutaneously transplanted tumors in the nude mice;its possible mechanism may be related to decreasing the activity of the PI3K/Akt signaling pathway.

Allergen-specific immunotherapy（AIT） remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis（AR）. Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group（CRRCG） convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.

Objective: Cardiac magnetic resonance (CMR) is a diagnostic tool that provides precise and reproducible information about cardiac structure, function, and tissue characterization, aiding in the monitoring of chemotherapy response in patients with lightchain cardiac amyloidosis (AL-CA). This study aimed to evaluate the feasibility of CMR in monitoring responses to chemotherapy in patients with AL-CA. Materials and Methods: In this prospective study, we enrolled 111 patients with AL-CA (50.5% male; median age, 54 [interquartile range, 49–63] years). Patients underwent longitudinal monitoring using biomarkers and CMR imaging. At followup after chemotherapy, patients were categorized into superior and inferior response groups based on their hematological and cardiac laboratory responses to chemotherapy. Changes in CMR findings across therapies and differences between response groups were analyzed. Results: Following chemotherapy (before vs. after), there were significant increases in myocardial T2 (43.6 ± 3.5 ms vs. 44.6 ± 4.1 ms; P = 0.008), recovery in right ventricular (RV) longitudinal strain (median of -9.6% vs. -11.7%; P = 0.031), and decrease in RV extracellular volume fraction (ECV) (median of 53.9% vs. 51.6%; P = 0.048). These changes were more pronounced in the superior-response group. Patients with superior cardiac laboratory response showed significantly greater reductions in RV ECV (-2.9% [interquartile range, -8.7%–1.1%] vs. 1.7% [-5.5%–7.1%]; P = 0.017) and left ventricular ECV (-2.0% [-6.0%–1.3%] vs. 2.0% [-3.0%–5.0%]; P = 0.01) compared with those with inferior response. Conclusion Cardiac amyloid deposition can regress following chemotherapy in patients with AL-CA, particularly showing more prominent regression, possibly earlier, in the RV. CMR emerges as an effective tool for monitoring associated tissue characteristics and ventricular functional recovery in patients with AL-CA undergoing chemotherapy, thereby supporting its utility in treatment response assessment.

Objective:To investigate the prognostic factors for liver transplantation for hepatocellular carcinoma beyond UCSF criteria but without macrovascular invasion.Methods:A retrospective analysis was performed for the clinical data of the hepatocellular carcinoma patients without macrovascular invasion beyond UCSF criteria who underwent liver transplantation at our center from Jan 2018 to Jun 2023. The receiver operating characteristic curve analysis was performed to assess the predictive power of potential prognosis factors.Results:With this criteria, the 1-, 3-year overall survival rates were 94.1% and 75.0%, respectively, and the 1-, 3-year tumor free survival rates were 82.4% and 38.1%, respectively. The maximum tumor size, number of tumors, AFP, PIVKA-Ⅱ before transplantation, and whether undergo pretransplant down-stage therapy were significant prognostic factors ( P<0.05). Combining the above prognostic factors to construct the receiver operating characteristic curve yielded an area under the curve of 0.967, with a sensitivity and specificity of 0.932, 0.952, respectively. Further, the differentiation, MVI and Ki-67 were significant prognostic factors ( P<0.05). Combining pathological factors to construct the receiver operating characteristic curve yielded an area under the curve of 0.927, with a sensitivity and specificity of 0.769, 1, respectively. Conclusion:The maximum tumor diameter, number of tumors, AFP, PIVKA-Ⅱ before transplantation, and pretransplant down-stage therapy and tumor differentiation, MVI and Ki-67 are all prognostic factors of liver transplantation for hepatocellular carcinoma without macrovascular invasion beyond UCSF criteria.

Objective:To investigate the immune cell differentiation-induced alveolar-capillary barrier damage in septic ARDS via cell communication.Methods:Construct septic ARDS-related WGCNA network based on transcriptomic data and identify ARDS-related genes (ARGs). Constructed septic ARDS differentiation trajectories, predicted cellular communication, and screened immunodifferentiation-related genes (IDRGs) based on single-cell sequencing data. Lasso regression analysis establish immune-related RS of ARDS. ESTIMATE, CIBERSORT, and ssGSEA assessed the immune microenvironment. Metascape, GSVA and GO enrichment analyses demonstrated RS-related signaling pathways and biological processes.Results:Cell communication between immune cells and fibroblasts/endothelial cells involves 22 signaling pathways. RS containing DSTN, SNRPA, and FGL2 were differentially expressed in healthy, sepsis, and septic ARDS patients, affecting the differentiation of immune cells, endothelial cells, and fibroblasts, and regulating the infiltration of the immune cells and immune functions. The characteristic immune cells in septic ARDS included memory B cells, plasma cells, CD8 +T, and M0; DSTN was negatively correlated with M0 ( r=-0.29, P<0.05), SNRPA was positively correlated with CD8 +T ( r=0.28, P<0.05), and FGL2 was positively correlated with memory B cells ( r=0.32, P<0.05).The immune cells that were differentially expressed between RS groups, including CD4 na?ve T cells, CD4 memory-activated T cells, regulatory T cells, γ-δ T cells, M0, and activated dendritic cells. Enrichment analysis indicated the differential expression of DSTN, SNRPA, and FGL2 affected the differentiation of immune cells, the activation of immune functions, the presentation of antigens, and the depolymerization/cutting of actin filaments. Conclusions:DSTN, SNRPA, and FGL2 affect immune-related alveolar-capillary barrier damage in septic ARDS by regulating the differentiation of immune cells, fibroblasts, and endothelial cells, and are potential biomarkers for predicting the progression of septic ARDS.
