芹菜水提物促进神经干细胞的体外分化

1IntroductionNeural stem cells have great potential for use intreating neural damage and neurodegenerative disor-ders such as Parkinson’s Disease and Alzhei mer’s Di-sease.They are undifferentiated elements found inboth the embryonic and adult brain[1].Growth factor-responsive cells fromthe embryonic and adult controlnervous system(CNS)were isolated and culturedinvitrointhe early1990’s[2-4].Thelocation of CNS stemcells in the adult brain were therefore identified[5]mainlyinthe striatum,…

CD_(40)-CD_(40)L相互作用对人脐静脉内皮细胞增殖及迁移的影响

目的探讨CD40-CD40配体相互作用对体外培养的人脐静脉内皮细胞(HUVEC)增殖及迁移的影响。方法采用Ⅱ型胶原酶消化法培养人脐静脉内皮细胞,以3H-胸腺嘧啶脱氧核苷(3H-TdR)、3H-亮氨酸(3H-Leu)掺入法分别测定HUVEC增殖,内皮细胞的迁移采用琼脂糖凝胶刮取法,倒置显微镜观察。结果CD40-CD40配体相互作用能明显促进HUVEC3H-TdR、3H-Leu的掺入,两者具有时间、剂量依赖性,CD40-CD40配体相互作用随CD40L浓度的增加及刺激时间延长(30h内),能明显增加内皮细胞迁移率,an-ti-CD40单克隆抗体能明显抑制上述效应。结论CD40-CD40配体相互作用能促进内皮细胞增殖、迁移。

Modeling life course pathways from adverse childhood experiences to adult mental health

Although the association between adverse childhood experiences (ACEs) and adult mental health is becoming well established, less is known about the complex and multiple pathways through which ACEs exert their influence. Growing evidence suggests that adversity early in life conveys not only early impacts, but also augments risk of stress-related life course cascades that continue to undermine health. The present study aims to test pathways of stress proliferation and stress embodiment processes linking ACEs to mental health impairment in adulthood. Data are from the 2011 Behavioral Risk Factor Surveillance Survey, a representative sample of Washington State adults ages 18 and over (N = 14,001). Structural equation modeling allowed for testing of direct and indirect effects from ACEs though low income status, experiences of adversity in adulthood, and social support. The model demonstrated that adult low income, social support and adult adversity are in fact conduits through which ACEs exert their influence on mental health impairment in adulthood. Significant indirect pathways through these variables supported hypotheses that the effect of ACEs is carried through these variables. This is among the first models that demonstrates multiple stress-related life course pathways through which early life adversity compromises adult mental health. Discussion elaborates multiple service system opportunities for intervention in early and later life to interrupt direct and indirect pathways of ACE effects.     

论“文革”对鲁迅的传播

＂文革＂对鲁迅的传播,具有与＂文革＂作为特殊时期高度一致的复杂性。鲁迅著作的出版受制于文革政治需要与当时的文化观念和运作方式,是极端计划经济条件下的一种制度化行为;鲁迅言论的引用表现出强烈的选择性,既显示了引用者的立场与态度,又参与了鲁迅形象的文革版的改写。     

不同模式低氧训练对大鼠脾淋巴细胞功能的影响

目的:研究不同模式低氧训练后大鼠脾淋巴细胞功能的变化,探讨机体免疫功能的变化规律。方法:120只大鼠按照氧环境(常氧、高住低练、低氧)和训练强度(无、中和高强度)随机形成9种组合,中等强度训练5周,高强度训练6周,测定淋巴细胞转化功能。结果:单纯的低氧环境和高强度训练均能显著上调B细胞分化功能,低氧高强度训练后B细胞分化功能进一步显著增强,HiLo环境则对T细胞功能具有显著抑制作用,但HiLo训练能减轻环境对T细胞的抑制;常氧下长期中、高强度训练后脾T细胞功能受抑,但低氧和HiLo训练后未见相同结果。     

IGF-II促MC3T3-E1细胞增殖和存活及影响NO水平的研究

目的　研究胰岛素样生长因子 2(IGF II)对小鼠成骨细胞株MC3T3 E1细胞促增殖、存活和影响一氧化氮(NO)水平的作用.方法　体外培养成骨细胞株MC3T3 E1细胞,分别加入不同浓度的IGF II,用MTT法、酶化学法检测MC3T3 E1细胞增殖和NO水平的变化.结果　IGF II对MC3T3 E1细胞有促增殖作用,在1～100ng/mL范围内呈浓度依赖性;第3天时100ng/mLIGF II组的NO水平明显低于对照组(P<0.01);培养5天和6天后,对照组细胞6天OD值明显低于5天OD值(P<0.01),而100ng/mLIGF II组细胞6天OD值则显著高于5天OD值(P<0.01).结论　IGF II能促进MC3T3 E1细胞的增殖,抑制细胞NO产生,并具有抗MC3T3 E1细胞死亡作用.

核军备控制理论中的无核区

无核区作为特定区域内国家核裁军、防止核扩散、建立互信措施的一种安全合作机制,也是一项具体的、操作性强的军备控制措施,或可以说是机制。根据军控理论,无核区属于军备控制的范畴,表现在核裁军与防止核扩散方面,即对核武器的“量”及“使用方式”的控削。
