Hereditary spastic paraplegia(HSP)is a clinically and genetically heterogeneous neurodegenerative disorder,characterized primarily by progressive spasticity and weakness in the lower *** ients can also experience peripheral neuropathy,cognitive impairment,and other neurological *** date,more than 80 genes have been implicated in HSP,encompassing various cellular components,although mutations in genes encoding endoplasmic reticulum(Er)-shaping proteins are the most prevalent(Parodi et al.,2017).Er-shaping proteins are generally known for regulating the tubulation and curvation of the Er,but most of them show additional functions,including fusion of Er tubules,microtubule-severing,Er autophagy,lipid droplet synthesis,contact sites with other organelles(Öztürk et al.,2020).This highlights the complexity of studying the role of these proteins and the link between Er function and HSP.

目的过去10年内人们愈发希望开发出可供胸主动脉功能成像的血管成像技术,本文即是为上述目的提供一种MrI和流体动力学相结合方法,以获得病人的具体血流动力学情况,即应用胸主动脉修复情况分析病人的治疗。方法首先以Mr扫描确定范围,然后用MrI的心电门控电影序列对整个胸主动脉区进行扫描,并用相位对比成像技术提供血管入口及出口情况进行流体动力学计算,再利用电影成像显示动脉形态模型,模拟血管壁运动,假设血流为均匀牛顿流体,并对有限体积进行流体动力学计算处理。结果针对14例病人(男性,平均年龄62.2岁)不同的主动脉病变进行评估,根据四维映射的速度和血管壁切面的压力得到不同模式的血流(层流、湍流及狭窄血流)以及沿原主动脉支架壁压力的改变。结论这种计算与MrI相结合的方法,能够提供胸主动脉支架植入后详细的功能学分析。
