BACKGROUND Irreversible electroporation(IRE)is a novel local tumor ablation approach with the potential to activate the host’s immune ***,this approach is insufficient to prevent cancer progression,and complementary approaches are required for effective *** To assess the immunomodulatory effects and mechanism of IRE combined antiprogrammed cell death protein 1(PD-1)treatment in subcutaneous pancreatic cancer *** C57BL-6 tumor-bearing mice were randomly divided into four groups:Control group;IRE group;anti-PD-1 group;and IRE+anti-PD-1 ***-infiltrating T,B,and natural killer cell levels and plasma concentrations of T helper type 1 cytokines(interleukin-2,interferon-γ,and tumor necrosis factor-α)were ***-time PCR was used to determine the expression of CD8(marker of CD8+T cells)in tumor tissues of the mice of all groups at different points of *** growth curves of tumors were *** The results demonstrated that the IRE+anti-PD-1 group exhibited significantly higher percentages of T lymphocyte infiltration,including CD4+and CD8+T cells compared with the control ***,the IRE+anti-PD-1 group showed increased infiltration of natural killer and B cells,elevated cytokine levels,and higher CD8 mRNA *** volume was significantly reduced in the IRE+anti-PD-1 group,indicating a more pronounced therapeutic *** The combination of IRE and anti-PD-1 therapy promotes CD8+T cell immunity responses,leading to a more effective reduction in tumor volume and improved therapeutic outcomes,which provides a new direction for ablation and immunotherapy of pancreatic cancer.

Accurate spatio-temporal land cover information in agricultural irrigation districts is crucial for effective agricultural management and crop production. Therefore, a spectralphenological-based land cover classification(SPLC) method combined with a fusion model(flexible spatiotemporal data fusion, FSDAF)(abbreviated as SPLC-F) was proposed to map multi-year land cover and crop type(LC-CT) distribution in agricultural irrigated areas with complex landscapes and cropping system, using time series optical images(Landsat and MODIS). The SPLC-F method was well validated and applied in a super-large irrigated area(Hetao) of the upper Yellow River Basin(YRB). Results showed that the SPLC-F method had a satisfactory performance in producing long-term LC-CT maps in Hetao, without the requirement of field sampling. Then, the spatio-temporal variation and the driving factors of the cropping systems were further analyzed with the aid of detailed household surveys and statistics. We clarified that irrigation and salinity conditions were the main factors that had impacts on crop spatial distribution in the upper YRB. Investment costs, market demand, and crop price are the main driving factors in determining the temporal variations in cropping distribution. Overall, this study provided essential multi-year LC-CT maps for sustainable management of agriculture, eco-environments, and food security in the upper YRB.
