The present study investigated the potential therapeutic potential of Ficus carica polysaccharides (FCPS) in type 2 diabetic (T2DM) mice， focusing on elucidating the underlying molecular mechanisms. Network pharmacology analysis identified 37 shared targets between FCPS and T2DM， including PPARα， highlighting the significance of PPAR signaling pathways in FCPS-mediated T2DM treatment. The results demonstrated that FCPS treatment significantly reduced markers of glucose and lipid metabolism (FBGL， NEFA， TG， TC， LDL-C)， inflammatory cytokines (TNF-α， IL-6， IL-1β， MCP-1)， and liver damage (GPT and GOT) in T2DM mice. Additionally， FCPS ameliorated hepatic lipid droplet accumulation， fatty degeneration， and hepatocyte structural abnormalities. Western blot analysis confirmed FCPS-induced upregulation of key proteins in the IRS-1/AKT/PPARα signaling pathway， (IRS-1， PI3K， p-AKT， GLUT2， p-GSK-3β， p-AMPKα， PGC-1α， PPARα， PPAR-γ) and downregulation of GSK-3β， SREBP-1c， FAS， and HMGCR. 16S rDNA sequencing results revealed FCPS's ability to modulate gut microbiota dysbiosis in T2DM mice by promoting beneficial bacteria (e.g.，Lactobacillus＿reuteri，Candidatus＿Saccharimonas) and suppressing opportunistic pathogens (e.g.，Proteobacteria， Gammaproteobacteria， Escherichia-Shigella). These findings collectively suggest that FCPS has a marked effectiveness in improving glucose and lipid metabolism， decreasing inflammatory responses， as well as modulating the gut microbiota in T2DM mice via the gut-hepatic axis， demonstrating its potential as a functional food for diabetes prevention and management.

下滑信标是仪表着陆系统的重要组成部分,为进近中的航空器提供垂直方位引导。进行障碍物对下滑信标信号影响的精确分析可以为导航台站选址及解决导航台运行中存在的问题提供理论依据。本文基于物理光学-物理绕射理论(Physical optics-physical theory of diffraction,PO-PTD)算法,结合空客A320-200型客机以及机场三维模型对下滑信标的下滑道结构影响进行了静态分析。在静态分析的基础上,对飞机在滑行道上滑行且五边上有飞机进近时的影响进行了动态研究,找出了某机场飞行员长期反映的下滑道信号不稳问题的原因。动态研究数据与飞行校验结果进行了比对并与飞行校验结果吻合。
