The microstructure, mechanical properties, and misorientation of automobile beam steels produced by EAF-CSP process were studied using optical microscopy （OM） and electron back-scattered diffraction （EBSD）. It is shown that the microstructure of strips is mainly polygonal ferrite, and the average grain size is about 5-8 μm. The electron back-scattered diffraction results show that grain boundaries in ferrite are basically high-angle grain boundaries without remarkable preferred orientation. Hot strips of automobile beam steels possess a good combination of strength and plasticity because of their fine microstructures and low quantity of impurities.

目的基于四维数据独立采集（4D-data-independent acquisition,4D-DIA）蛋白质组学技术探究表柔比星所致化疗相关认知障碍（chemotherapy-induced cognitive impairment,CICI）发生机制。方法用小鼠脑微血管内皮细胞bEnd.3构建体外血脑屏障模型，随机分为表柔比星组和空白对照组，表柔比星组接受5μmol/L表柔比星处理24 h，对照组未进行任何特殊处理。利用4D-DIA技术检测并比较两组间差异蛋白的表达，对差异蛋白进行基因本体分析（gene ontology,GO）及京都基因和基因组百科全书（Kyoto Encyclopedia of Genes and Genomes,KEGG）富集分析，并构建蛋白-蛋白相互作用（protein-protein interaction,PPI）网络。结果通过对比分析，表柔比星组和空白对照组共鉴定出1 282种差异蛋白，其中显著上调蛋白378种，显著下调蛋白904种。GO分析显示差异蛋白主要富集于细胞内，参与生物调节、有机物代谢及细胞代谢等生物学过程，并与结合、催化等分子功能有关。KEGG通路分析显示，差异蛋白与剪接体、RNA聚合酶、mRNA监控通路的相互作用等有关。蛋白-蛋白相互作用网络（protein-protein interaction,PPI）分析显示，TP53、RNA解旋酶DHX15、小核核糖核蛋白肽D3等处于中心位置，其分别与凋亡、剪接体相关。结论表柔比星可能通过破坏脑微管内皮细胞的剪接体功能、影响正常连接及转运系统，进而诱发化疗相关认知障碍。

Based on analyzing actual cases and referring to other discourses, this discourse analyzes the happiness of teachers in non-governmental funded universities from three perspectives： the subjectivity of ＂happiness＂, psychological condition and the influence of career. As a result, this discourse can find tools for evaluating happiness and use them to evaluate the degree of happiness in non-governmental funded universities.
