Oxidized cholesterol (OXC) is a harmful dietary substance. Although the consumption of OXC has been associated with colonic inflammation， related underlying mechanisms are still limited. We evaluated the influence of dietary OXC on gut health and ecology by applying the murine model. Results showed that the thickness of the mucus layer was significantly reduced in healthy mice treated with OXC. Short-term intake of OXC did not influence the expression of pro-inflammatory factors in healthy mice but it induced the decrease of Muc2 expression in the proximal colon， accompanied by an increase in the abundance of two mucus-degrading bacteria， namely A. muciniphila and B. acidifaciens. Consistently， oral exposure of OXC promoted mucus barrier erosion in DSS-induced colitis mice and facilitated bacteria infiltration in the colon. The adverse effect of OXC on mucus layer disappeared in antibiotics-treated healthy mice， suggesting that the damaging effect of OXC on the gut mucus layer was not direct and instead was mediated by causing microbiota dysbiosis. Finally， the impact of OXC on the mucus layer and colitis was partly alleviated by green tea catechins. These studies demonstrated that the OXC-induced mucus barrier damage was mainly induced by the dysregulation of gut microbiota at least in this mouse model.

转喻是一种以此概念表达彼概念的手段,是多模态的。转喻可以体现在语言的词语、句子、篇章层面。概念系统是多模态的、立体的。语言表达是线性的,不可避免地带有“以小指大”“以点带面”“以部分代整体”等特点,因而表现出选择性、模... 详细信息

转喻是一种以此概念表达彼概念的手段,是多模态的。转喻可以体现在语言的词语、句子、篇章层面。概念系统是多模态的、立体的。语言表达是线性的,不可避免地带有“以小指大”“以点带面”“以部分代整体”等特点,因而表现出选择性、模糊性、经济性等特征。语言表达很大程度上是转喻性的。大部分的间接表达或者间接言语行为都是转喻。汉语由于其独特的构词方式、语法特征,以及倾向于间接表达和模糊思维等特点,是一种高度转喻性的语言。

不公平厌恶分为不利不公平厌恶和有利不公平厌恶。为了考察儿童不公平厌恶的发展特点,实验1和实验2通过设置真实的分配情境,采用分配额外资源任务的变式,分别研究分配方式和内外群体对5~7岁儿童不利不公平厌恶的影响以及分配方式和声誉对7~9岁儿童有利不公平厌恶的影响。结果发现:不利不公平厌恶随儿童年龄增长而降低,7岁是转折年龄;有利不公平厌恶随儿童年龄增长而升高,8岁是转折年龄;自我分配和内群体成员引起的不利不公平厌恶低于他人分配和外群体成员,但两种分配方式下的儿童有利不公平厌恶均较低;声誉会增加儿童的有利不公平厌恶,且在年龄上表现出不平衡性。研究说明儿童两类不公平厌恶的年龄发展趋势不同,并且会受到分配方式以及内外群体或声誉等因素的影响。

通过方差分析、主成分分析和商值法探究了上海淀山湖28个表层沉积物中56种卤代阻燃剂(HFRs)的时空分布特征、污染源及潜在生态风险.结果表明,上海快速工业化和城市化进程导致典型水源地淀山湖表层沉积物中3种HFRs出现明显累积,其中替代型溴代阻燃剂(Σ_(22)ABFRs,21.418ng/g)浓度已超出传统溴代阻燃剂(Σ_(23)PBDEs,10.344ng/g)约2倍.十溴联苯醚(BDE209,7.890ng/g),十溴二苯乙烷(DBDPE,17.990ng/g)和得克隆(Σ_(Syn+Anti)DP,1.176ng/g)是最主要的同系物.这些HFRs的高值点主要出现在环湖生活生产活动较密集的淀山湖西南区域,季节性差异不显著.主成分分析法揭示出商用十溴、五溴和八溴二苯醚及其替代品的使用,以及含新型阻燃剂的塑料制品的使用是主要来源.基于商值法的风险评估揭示出五溴联苯醚、BDE209、DBDPE、2,4,6-三溴苯氧基乙烷(BTBPE)和2-乙基己基-2,3,4,5-四溴苯甲酸酯(TBB)在绝大多数沉积物中对底栖生物均呈现中等风险,BDE209在个别采样点出现高风险,表明未来对这些卤代阻燃剂的环境监管仍需加强.

从读研究生开始,我就对没骨画有着浓厚的兴趣,开始临摹居巢、居廉的画。经过近十年的努力,我对没骨技法有了一定的掌握,从开始要打形敷色,到现在可直接从某个局部开始,笔笔生发,一气呵成。我领悟到只有多写生,才能掌握没骨花卉的精髓。三月的桃花、玉兰盛开如霞如雪,四月的丁香、牡丹香气四溢……每到花开季节,我都会观察花草最精彩、最触动人的地方,再用笔尖记录下来,创作一些精巧的小作品。将这些四季花卉用画笔记录下来,是一场不错的笔尖旅行。
