Complex pathologies of angiotensin II-induced abdominal aortic aneurysms

Angiotensin II (AngII) is the primary bioactive peptide of the renin angiotensin system that plays a critical role in many cardiovascular diseases. Subcutaneous infusion of AngII into mice induces the development of abdominal aortic aneurysms (AAAs). Like human AAAs, AngII-induced AAA tissues exhibit progressive changes and considerable heterogeneity. This complex pathology provides an impediment to the quantification of aneurysmal tissue composition by biochemical and immunostaining techniques. Therefore, while the mouse model of AngII-induced AAAs provides a salutary approach to studying the mechanisms of the evolution of AAAs in humans, meaningful interpretation of mechanisms requires consideration of the heterogeneous nature of the diseased tissue.

2000—2010年中国古代人口思想研究综述

2000—2010年的中国古代人口思想研究包括宏观人口思想探讨和分人物人口思想研究两部分。研究的特点为重视古代人口思想对当代人口理论构建的意义;思路严谨,资料翔实;古代学者思想的合理性与局限性共存。不足之处为范围较小、数量较少、深度不够。因而该项研究还应该不断拓宽学术视野,在深入挖掘中国古代人口思想的基础上得出更加科学合理的结论。     

从NSSE-CHINA看我国高等教育质量保障

＂中国大学生学习投入性调查＂（NSSE-CHINA）正得到越来越多的关注。NSSE—CHINA推动了质量文化的生成,尊重学生体验,促使高等教育质量保障主体多元化,对高等教育质量保障具有重要意义。通过对NSSE—CHINA进行反思,发现当务之急是围绕不同层次、类型高校的人才培养目标和规格构建多元分层的NSSE—CHINA体系,并加强NSSE—CHINA与其他高等教育质量保障机制的有机结合,以使NSSE—CHINA在高层次上推动我国高等教育质量保障体系的完善。     

从中国文学史的背景看赵树理的“三农”文学

自《诗经》始,中国文学素有"兴农"、"乐农"、"悯农"的传统,尤其是五四新文化运动以来,描写农业、农村、农民的"三农"文学在表现农民苦难、农村凋敝、乡村批判、农民的觉醒与反抗、农民进城等五个方面有了长足的发展。在此背景下,赵树理创作的个性特征可以得到清晰的体认:始终立足于黄土地,与农村、农民保持着血脉相连的关系;致力于表现农村错综复杂的社会关系,表现农业生产方式、乡村社会结构的变迁以及这一过程中农民的命运与心态的变化;反映出带有晋东南特征的农村社会伦理状况,表明了国民性批判线索的历史性超越;执著地追求乡野风格,其作品带有浓郁的乡土趣味。赵树理是现代文学史上从精神内涵到文体形式、审美风格整体上最能代表农民的作家。赵树理对于当今文学创作仍有启迪意义。

苏联的“边缘化”与第二次世界大战的爆发

苏联的出现引起民了西方资本主义大国的不安，基于意识形态和一战后世界和平的考虑，苏联排斥在巴黎和会之外，这种安排上使苏联处于欧洲的边缘。“边缘化”政策导致欧洲均势的破坏，在某种程度上，促成了二战的爆发。     

Availability and toxicity of Fe(II) and Fe(III) in Caco-2 cells

The objective of the present study was to compare the toxicity and availability of Fe(II) and Fe(III) to Caco-2 cells. Cellular damage was studied by measuring cell proliferation and lactate dehydrogenase (LDH) release. The activities of two major antioxidative enzymes [superoxide dismutase (SOD) and glutathione peroxidase (GPx)] and differentiation marker (alkaline phosphatase) were determined after the cells were exposed to different levels of iron salts. The cellular iron concentration was investigated to evaluate iron bioavailability. The results show that iron uptake of the cells treated with Fe(II) is significantly higher than that of the cells treated with Fe(III) (P<0.05). Fe(II) at a concentration >1.5 mmol/L was found to be more effective in reducing cellular viability than Fe(III). LDH release investigation suggests that Fe(II) can reduce stability of the cell membrane. The activities of SOD and GPx of the cells treated with Fe(II) were higher than those of the cells treated with Fe(III), although both of them increased with raising iron supply levels. The results indicate that both Fe(II) and Fe(III) could reduce the cellular antioxidase gene expression at high levels.
