Journal of Materials Science & Technology 2010年第1期26卷 15-19页

作者： Lutang fu zhigang Chen Hongtao Cong Shenyang National Laboratory for Materials Science Institute of Metal Research Chinese Academy of Sciences 72 Wenhua Road Shenyang 110016 China

GaPO4-GaN coaxial nanowires were synthesized by two-step chemical vapor deposition method using H2 and NH3 as reactant gas in turn at 950℃. The morphology and microstructures of the GaPO4-GaN coaxial nanowires were studied by scanning elctron microscopy （SEM）, X-ray diffraction （XRD） and transmission electron microscopy （TEM）. The nanowires have an average diameter of -15 nm and length of hundreds of nanometers. The core is GaPO4 crystal and the outer shell is GaN crystal. The formation mechanism was discussed and the key factors controlling the growth are temperature and the concentration of reactant gases. These coaxial nanowires may have potential application for piezoluminescence nano-devices, and the two-step synthetic technique could be used to grow rationally other 1D GaN-based nanowire heterostructures.

门脉高压性肺动脉高压:诊治进展与挑战

基础医学与临床 2024年第8期44卷 1068-1073页

门脉高压相关性肺动脉高压(PoPH)是门静脉高压患者的并发症之一,死亡率较高,预后差。目前发病机制尚不明确,高动力循环、血管活性物质的失衡、遗传因素以及炎性反应可能共同参与了其病理过程。目前,尚未发现针对PoPH的特异性治疗方法或... 详细信息

门脉高压相关性肺动脉高压(PoPH)是门静脉高压患者的并发症之一,死亡率较高,预后差。目前发病机制尚不明确,高动力循环、血管活性物质的失衡、遗传因素以及炎性反应可能共同参与了其病理过程。目前,尚未发现针对PoPH的特异性治疗方法或药物。虽然内皮素受体拮抗剂、前列环素及其类似物、磷酸二酯酶5抑制剂以及鸟苷酸环化酶激活剂等药物已经被用于治疗PoPH患者,但这些药物的疗效和安全性还需通过大规模的临床试验进行验证。肝移植对于部分患者可能带来益处,但也需要综合评估患者的具体情况。本文对PoPH的诊断、流行病学、病理生理学及目前的治疗策略进行了文献梳理,旨在提高对该疾病的认识,促进诊断和治疗水平的提升。未来研究的方向应包括发掘新的治疗药物、评估现有治疗方法的长期效果,以及为PoPH患者提供更为有效和安全的治疗方案。

目的:探讨锌缺乏与成人慢性呼吸系统疾病单位时间内急性加重次数之间的关系。方法:回顾性选择2022年1月-2023年12月佛山市南海区第七人民医院呼吸与危重症医学科收治的49例患者资料为研究对象,根据病案资料及辅助检查结果将其分为试验组(n=26)和对照组(n=23)。试验组为慢性呼吸系统疾病患者,对照组为非慢性呼吸系统疾病患者。对两组进行血清锌含量检测,根据结果在两组中各自分成锌缺乏亚组与锌正常亚组,并统计所有患者在研究期间罹患呼吸道感染且需要抗生素或抗病毒药物干预的次数(以下简称急性感染次数)与锌缺乏的关系。结果:在49例患者中,总缺锌39例(79.59%)。试验组中缺锌4例(15.38%),边缘性缺锌17例(65.38%);对照组缺锌8例(34.78%),边缘性缺锌10例(43.48%),两组锌缺乏情况比较,差异无统计学意义(P>0.05)。试验组急性感染次数多于对照组,差异有统计学意义(P0.05)。结论:锌缺乏会导致机体免疫力下降,进而容易引起呼吸道感染,其在有慢性呼吸道基础疾病患者中尤为明显,在慢性呼吸道疾病患者的日常管理中,需要更加注重维持微量元素锌的稳态。

国际媒体深入报道打破处于“失语”状态的红军长征,为中国共产党形象构建提供了良好的传播契机。长征的国际传播不仅突破长征中中国共产党舆论的困境,更为重要的意义在于通过长征的国际叙事,形塑了一批年轻的优秀红军战士,在国际舆论中开始形成一个生机勃勃的“红色中国”,树立起中国共产党的国际形象。长征的国际传播具有重要意义,透过业已形成的长征符号,能够消解意识形态的偏见,从而将长征波澜壮阔的历史图景与坚韧不屈的革命精神融入马克思主义中国化的历程,向世界展现中国共产党在现实与未来世界中的地位。

适时调整工作重心、转换城乡关系是中国共产党在革命与建设时期与时俱进的重大战略举措。新中国成立前,中国共产党为夺取政权开辟了"农村包围城市"的革命道路,奠定了革命成功的基础。但随着时局变化,党的工作重心在建政后发生了巨变,即将执掌全国政权的中国共产党以"城乡兼顾"原则处理"城市与乡村的阻隔",着力发展交通运输、打通全国市场、重建商业网络,最终通过建立大区级、地区性、基层等三个市场层级逐步扭转城乡阻隔的局面,改变了近代以来畸形的城乡关系结构,为新中国成立初期"城乡互助"的局面创造了条件。
