Background With an aggravated social ageing level, the number of patients with Alzheimer's disease (AD) is gradually increasing, and mild cognitive impairment (MCI) is considered to be an early form of Alzheimer's disease. How to distinguish diseases in the early stage for the purposes of early diagnosis and treatment is an important topic. Aims The purpose of our study was to investigate the differences in brain cortical thickness and surface area among elderly patients with AD, elderly patients with amnestic MCI (aMCI) and normal controls (NC). Methods 20 AD patients, 21 aMCIs and 25 NC were recruited in the study. FreeSurfer software was used to calculate cortical thickness and surface area among groups. Results The patients with AD had less cortical thickness both in the left and right hemisphere in 17 of the 36 brain regions examined than the patients with aMCI or NC. The patients with AD also had smaller cerebral surface area both in the left and right hemisphere in 3 of the 36 brain regions examined than the patients with aMCI or NC. Compared with the NC, the patients with aMCI only had slight atrophy in the inferior parietal lobe of the left hemisphere, and no significant difference was found. Conclusion AD, as well as aMCI (to a lesser extent), is associated with reduced cortical thickness and surface area in a few brain regions associated with cognitive impairment. These results suggest that cortical thickness and surface area could be used for early detection of AD.

目的探讨不同性别流浪精神病患者特点及总结护理要点。方法对本院2014年7月-2015年7月收治的流浪精神病患者1165例进行回顾性分析,比较不同性别流浪精神病患者其院内感染、攻击行为、肇事肇祸行为、约束情况发生率及日常生活能力情况。结果 1165流浪精神病患者中,男性患者735例,占63.1%,女性患者430例,占36.9%;男性流浪精神病患者医院感染、攻击、肇事肇祸、约束情况发生率及日常生活依赖程度明显高于女性患者,男女比较,均P〈0.01,差异具有统计学意义。结论流浪精神病患者中男性多于女性,而且男性患者攻击、肇事肇祸及住院后约束率、日常生活依赖程度明显高于女性患者,提示对不同性别流浪精神病患者应有侧重性采取针对性护理防范措施。

Dear Editor,Soil microbial biodiversity loss caused by agricultural intensification, climate change, and the application of chemical fertilizer has become a serious problem that threatens humans (Wall et al., 2015). One phenomenon responsible for economic and food security issues is soil-borne diseases(Fisher et al., 2012), which were reported to be associated with microbial diversity loss (Shen et al., 2013;Fu et al.,2017).

中国的"乡土文学"因其现代意识而与世界文学时刻处在互动之中,也与中国文化、社会、历史深具精神关联,是感知现代中国文学之中国-世界、传统-现代丰富性的最好入口,也是研究现当代中国本土文学的一个极佳样本,为我们提供了中国文学在本土-民族-世界的维度中如何继承开拓的可贵经验,是探究当代"中国问题"的一个有效维度。目前已有的研究,大多局限于"乡土文学"的内部研究,忽略了"乡土文学"早期的理论建构特点及这一概念产生的社会土壤、历史语境和文化动因。本文从社会学、历史学以及地域文化等角度综合考察"乡土文学"的缘起及其为何被命名为"乡土文学",探讨"乡土文学"发展中的"中国经验",在"乡土文学"的发展与流变中窥探其与中国文学乃至世界文学的丰富联系。

现代文学乡愁的相关书写十分繁盛,从鲁迅和周作人的示范开始,就极力克制私人化的情感倾泻,倡导有利于国家民族的国民改造式的乡愁表达。对Nostalgia一词内涵中单纯的怀乡病的否定是中国式乡愁具有的向外之现代性与向内之现实性,现代性的一面是中国式乡愁与19世纪以来的国外乡愁书写的应和,蕴含着对人类精神故乡和未来发展的指引性的一面;现实性是指中国式乡愁对现代中国的社会有深切的关注,有立志于改造社会,启蒙民众的内部之用。在左翼文学界对乡愁的书写如火如荼之际,乡愁也进入了电影的视野,尤其是战争和灾害损害下的乡村格外受到关注,通过影视的再造,个体的故乡记忆和乡愁书写与家国乡愁同频共振,乡愁转变成了国愁,起到了团结民心、民族认同的作用。遗憾的是,学界对乡愁理论的提炼远远滞后于乡愁的文艺书写。
