肠道屏障保持机体内环境稳定,当肠黏膜受损、肠道细胞间紧密连接被破坏和肠道菌群失调时会引发多种疾病。天然活性蛋白在肠道屏障修复中起着关键作用,乳铁蛋白是存在于哺乳动物乳汁中的糖蛋白,具有抗氧化、抗炎和抗菌等多种生物学功能。大量研究表明乳铁蛋白能够增强肠道紧密连接蛋白水平,促进肠细胞生长发育,下调炎症因子表达,调节免疫反应和肠道微生物多样性,参与维持肠道屏障稳态。本文对乳铁蛋白缓解肠道屏障功能障碍研究进展展开综述,有助于了解乳铁蛋白在肠道损伤中的作用机制,为乳铁蛋白制品干预肠道疾病提供参考。

A long-range phase-sensitive optical time-domain reflectometry is proposed and experimentally demonstrated, based on the gated Raman amplification （RA）. This technique can reduce the amplified spontaneous emissions （ASE） noise of the Raman pump while extend the sensing distance. A direct-detection based phase-sensitive optical time-domain reflectometry （O-OTDR） with an operation range of 50 km and a spatial resolution of 20 m has been demonstrated. The influence of different delay time of the gated Raman pump on the O-OTDR system is also discussed.

以种族殖民政策为内核的文化生存环境,使美国黑人一直身处多元文化视野却被制约在一元文化即WASP(白人·盎格鲁-撒克逊·新教)的范式中。作为“顺承者”的他们人格被扭曲,暴力变成他们在新种族主义体制中自我认同的一种手段。40年代黑人作家赖特在其成名作《土生子》中,以人名和书名构成比喻性美学符号以解构该传统的文化模式,它不仅表明了黑人具有黑人性及美国性的双重属性,还迫使黑人民族文化被纳入美国文化视野,为发展多元社会文化表征系统提供了可能。

A series of Ni-Cr-Fe welding wires with different Nb and Mo contents were designed to investigate the effect of Nb and Mo on the rnicrostructure, mechanical properties and the ductility-dip cracking susceptibility of the weld metals by optical microscopy （OM）, scanning electron microscopy, X-ray diffraction as well as the tensile and impact tests. Results showed that large Laves phases formed and distributed along the interdendritic regions with high Nb or Mo addition. The Cr-carbide （M23C6） was suppressed to precipitate at the grain boundaries with high Nb addition. Tensile testing indicates that the ultimate strength of weld metals increases with Nb or Mo addition. However, the voids formed easily around the large Laves phases in the interdendritic area during tensile testing for the weld metal with high Mo content. It is found that the tensile fractographs of high Mo weld metals show a typical feature of interdendritic fracture. The high Nb or Mo addition, which leads to the formation of large Laves phases, exposes a great weakening effect on the impact toughness of weld metals. In addition, the ductility-dip cracking was not found by OM in the selected cross sections of weld metals with different Nb additions. High Nb addition can eliminate the ductility-dip cracking from the Ni-Cr-Fe weld metals effectively.

Effects of the aging temperature on the hardening response, the tensile properties and the precipitate micro- structure evolution of 1460 alloy were studied in this work. It was found that Al3 （Sc, Zr） and δ′ （Al3li） phases were precipitated from the matrix at the very early aging stage, while the precipitation of T1 （Al2Culi） and θ′ （Al2Cu） was much slower than that of the δ′ phase. When aging at higher temperature （160 and 190 ℃）, the δ′, T1 and θ′ phases tended to form simultaneously and grow up very quickly. Conversely, the δ′ and θ″ （Al2Cu） phases were precipitated separately and more dispersive at lower aging temperature （130 ℃）. Taken together, the alloy aged at 160 ℃ exhibited improved mechanical properties owing to the uniform dispersion of the fine T1 precipitates.
