The aortic size above and below the mycotic aneurysm may be small. METHODS： A retrospective review was made of prospectively collected departmenta computerised database. RESULTS： Three oriental patients with juxta- and infra-renal mycotic aortic aneurysms with a small aortic diameter of 17 mm to 18 mm underwent successful emergency endovascular treatment using Cook Zenith ELSE stentgraffs. These are ancillary devices aimed at iliac extensions usually. CONCLUSIONS： This is to our knowledge the first case series of Cook Zenith ELSE iliac component endografts for the treatment of aortic mycotic aneurysms with small aortae, and short- and mid-term results are encouraging.展开更多
利用河北太行山区东高昌村2016−2019年土地流转数据,运用ESL(energy system language)模型对河北太行山区土地流转前后过程进行模拟评价,基于土地利用情景和劳动力投入视角进一步模拟了土地流转后系统能量变动情况.结果表明:1)土地流转...利用河北太行山区东高昌村2016−2019年土地流转数据,运用ESL(energy system language)模型对河北太行山区土地流转前后过程进行模拟评价,基于土地利用情景和劳动力投入视角进一步模拟了土地流转后系统能量变动情况.结果表明:1)土地流转后农作物生物量、资本及生态环境相比土地流转前均有显著提升.10年后农作物生物量、资本和林地生物量分别达到土地流转前的12.97、2.10、36.54倍;50年后农作物生物量、资本和林地生物量分别达到土地流转前的15.34、4.23、39.22倍;100年后农作物生物量、资本和林地生物量分别达到土地流转前的26.79、7.39、66.60倍.2)改变种植结构的流转效果一般,但调整劳动力投入结构使土地流转后的南瓜生物量和资本呈现倒“U”形变化趋势,南瓜生物量在24年达到峰值,资本在48年达到峰值.投入当地劳动力使农作物生物量提高46.5%,资本提高212%,效果最为显著.展开更多
