为提高垃圾焚烧炉过热器的抗高温氧化和磨损性能,采用两种不同硼含量的NiCrB粉芯丝材,通过电弧喷涂方法在SA213-T2钢基体表面制备涂层,并对涂层的微观组织结构、高温氧化行为和显微硬度与商用NiCrTi涂层进行对比研究。结果表明:制备的NiCrB涂层呈典型的层状结构,孔隙率约为3%,氧化物含量较低,涂层的显微硬度明显高于NiCrTi涂层。NiCrB涂层在800℃下的氧化增重明显低于基体,其中B含量较低的NiCrB涂层氧化动力学曲线呈典型的抛物线形式,表面生成了连续致密的Cr_2O_3氧化膜,有效阻止了氧向涂层内部的渗透,对基材起到较好的防护作用,抗高温氧化性能略低于NiCrTi涂层。

Mononuclear macrophage infiltration in the central nervous system is a prominent feature of neuroinflammation. Recent studies on the pathogenesis and progression of multiple sclerosis have highlighted the multiple roles of mononuclear macrophages in the neuroinflammatory process. Monocytes play a significant role in neuroinflammation, and managing neuroinflammation by manipulating peripheral monocytes stands out as an effective strategy for the treatment of multiple sclerosis, leading to improved patient outcomes. This review outlines the steps involved in the entry of myeloid monocytes into the central nervous system that are targets for effective intervention: the activation of bone marrow hematopoiesis, migration of monocytes in the blood, and penetration of the blood–brain barrier by monocytes. Finally, we summarize the different monocyte subpopulations and their effects on the central nervous system based on phenotypic differences. As activated microglia resemble monocyte-derived macrophages, it is important to accurately identify the role of monocyte-derived macrophages in disease. Depending on the roles played by monocyte-derived macrophages at different stages of the disease, several of these processes can be interrupted to limit neuroinflammation and improve patient prognosis. Here, we discuss possible strategies to target monocytes in neurological diseases, focusing on three key aspects of monocyte infiltration into the central nervous system, to provide new ideas for the treatment of neurodegenerative diseases.

目的探讨PRKCQ-AS1在气道平滑肌细胞(airway smooth muscle cells,ASMCs)的作用。方法首先通过转录组测序技术(RNA-seq)检测哮喘儿童肺泡灌洗液中的差异表达基因(differentially expressed genes,DEGs)。随后,分别构建PRKCQ-AS1慢病毒敲低和过表达载体并转染ASMCs。qRT-PCR方法检测了ASMCs中PRKCQ-AS1的表达;用CCK-8和流式细胞术分别检测ASMCs的增殖和凋亡;酶联免疫吸附测定(enzyme-linked immunosorbent assay,ELISA)检测ASMCs培养上清液中TNF-α和IL-1β的含量;lncRNA芯片检测PRKCQ-AS1敲低后的DEGs并进行KEGG通路富集;Western blot检测p-Akt和Akt的水平。结果RNA-seq结果显示,PRKCQ-AS1是上调最明显的DEGs之一。PRKCQ-AS1过表达促进了ASMCs的增殖和迁移并抑制了其凋亡,同时,PRKCQ-AS1过表达使上清液中炎性因子TNF-α和IL-1β的水平升高,而PRKCQ-AS1敲低则呈现相反的结果。对PRKCQ-AS1敲低后得到的606个DEGs进行KEGG信号通路富集分析,结果显示PI3K-Akt信号被明显富集。Western blot结果表明,PRKCQ-AS1敲低抑制了Akt的活化;相反,PRKCQ-AS1过表达则促进了Akt的水平。结论PRKCQ-AS1可能通过增强Akt信号促进ASMCs炎症反应,进而加剧了ASMCs的增殖和迁移,最终导致哮喘的发展。

According to a uniform and simple method of calculating spin-lattice coupling coefficients and the pert1rbation formulas of gi factors and hyperfine structure constants Ai based on the cluster approach for 3d7 ions in cubic,tetragonal and trigonal octahedral crystal fields, the spin-lattice coupling coefficients Fij (F11, Fl2, F44), Zij (Z11, Z12,Z44) and also g factor and hyperfine constant A for MgO:Co2+ are calculated by using the parameters obtained from the optical spectra without adjustable parameters. The calculated results show good agreement with the observed *** difiiculty in explaining the coeficients Fij and Zij is therefore removed.
