To the Editor:Lipoprotein glomerulopathy (LPG) is an uncommon inherited renal disease characterized by lipoprotein thrombi in the markedly dilated capillary lumina of affected glomeruli, high plasma concentrations of apolipoprotein E (apoE), and proteinuria.[1] It mainly affects people of Japanese and Chinese origin, and approximately 117 cases have been reported to date.[2,3] Several genetic studies have demonstrated that APOE gene mutations may lead to the development of LPG;[4,5,6] however, conflicting published evidence has found that some patients with APOE variants were unaffected.[7] Thus, further studies are needed to examine the role of APOE mutations in the pathogenesis of *** study investigated a novel point mutation in the APOE gene in a family with one LPG patient and an asymptomatic carrier of the same APOE variant.

广州美术学院图书馆保存着胡一川在1960年代初期对塞尚(Paul Czanne)画册的频繁借阅记录,这提示了1949年之后体制内艺术家们和西方现代艺术的复杂关系,也启发我们对革命美术的创新机制进行更深入的讨论。如代表了革命美术新风尚的一批"土油画"——胡一川的《开镣》(1950)、《前夜》(1961)等,这些作品既包含了对后印象派等西方现代艺术的语言转化,同时也是抗战时期文艺界跨媒介实践的后果:画面体现出戏剧舞台经验嵌入美术创作的新方法。本文回顾了艺术家"洋画""新兴木刻"和"土油画"的三个阶段,试图从东亚现代艺术史的视野来解读胡一川的艺术创作和现代艺术认知的独特性。穿梭在战争、革命文化和现代艺术个体实践交集的各种历史场合,由此展开对现代美术史"表"与"里"的悖论性思考。

1946年,李桦策划"抗战八年木刻特展"之际,撰文详细阐释了"新启蒙运动"的概念,并与"五四运动"进行了明确区分。这一迄今少有关注的历史观念表述,微妙地牵连出现代木刻与现代洋画运动的互动和历史渊源,也反映了战时现代艺术经历的深刻变局的多重面向:一者绘画语言,二者组织形态,三者价值观念。三者之间更有密切的互渗互动,逐渐生成了以新现实主义为中心议题的战时美术生态。本文回顾了1934年李桦主持编辑的《现代版画》杂志的跨文化跨媒介实践,由此追溯面临抗战爆发的历史临界点,民族国家和现代艺术家之间复杂关系的生成过程。
