简介:采用共沉淀法制备了不同Zn掺杂量的Li(Ni1/3Co1/3Mn1/3)1-xZnxO2(x=0-0.08)固溶体,通过X射线衍射(XRD)和光电子能谱(XPS)分析,研究了不同Zn掺杂量对Li(Ni1/3Co1/3Mn1/3)1-xZnxO2固溶体晶体结构和过渡金属表面化学状态的影响。实验结果表明:当Zn掺杂量x小于0.006时,固溶体材料具有稳定的层状结构;微量Zn的掺杂能够增强晶体材料的整体键能。
简介:摘要人类表皮生长因子受体2(humanepidermalreceptor2,HER-2)阳性乳腺癌是一组预后极差的乳腺癌,治疗后复发率高、复发时间早(复发高峰在治疗后3年内)、死亡率高。目前通过分子靶向治疗(赫赛汀)可以显著降低HER-2阳性乳腺癌患者的复发率、延长生存时间。但是,赫赛汀治疗价格昂贵,且不纳入医保支付范围,给患者带来巨大经济困难。胰岛素样生长因子Ⅱ受体(insulin-likegrowthfactor-Ⅱreceptor,IGF-ⅡR)是一个与乳腺癌生长密切相关的细胞膜受体。现已有研究表明不同IGF-ⅡR表达状态的患者之间有着截然不同的生存率。本研究旨在如果能够在不影响疗效的前提下,根据不同IGF-ⅡR表达状,是否能作为指导来缩小赫赛汀的适应症范围,有助于减少过度治疗,减轻患者经济负担。
