低聚果糖与低聚半乳糖在婴幼儿配方乳粉中的精准化应用

母乳是婴幼儿营养配方的金标准,而低聚糖是母乳重要的活性成分。我国母乳喂养婴幼儿平均每天摄入3.5~6.4 g母乳低聚糖,而婴幼儿配方乳粉（以下简称“婴配粉”）喂养婴幼儿平均每天摄入的低聚果糖与低聚半乳糖仅0.6~3.0 g。为精准模拟母乳低聚糖的作用,低聚果糖与低聚半乳糖的含量至关重要。因此,低聚果糖与低聚半乳糖在婴配粉中的添加量有必要适当提高。     

低血糖生成指数液态奶的开发及测试

为获得营养均衡的调制牛奶,满足人体的多种营养需求,添加多种维生素和矿物质,设计出一款适用于糖尿病人、亚健康人群、体重管理、皮肤管理等人群饮用的低血糖生成指数（Glycemic Index,GI）的牛奶。稳定性试验结果表明,静置12 天后,牛奶无显著脂肪上浮,体系稳定性良好;人体GI值试验结果表明,调制牛奶的餐后血糖值上升和下降均较葡萄糖餐后血糖值平稳,有较好稳定餐后血糖的效果,表明开发的调制牛奶为低GI食品（GI值=22.86）。人体饱腹感试验结果显示,和普通纯牛奶对比,调制牛奶具有显著提高饱腹感的效果。     

《国家人权行动计划（2009～2010）》对实现“国家尊重和保障人权”宪法原则的意义

2009年4月13日,国务院新闻办公室发布了《国家人权行动计划（2009～2010）》。这是以我国政府名义制定的第一个以保障人权为主题的国家层面规划,是一份政府各部门落实＂国家尊重和保障人权＂的宪法原则,推进中国人权事业发展的行动纲领性质的政策文件。本文拟从介绍《国家人权行动计划（2009～2010）》的出台背景、指导思想、基本原则、主要内容等方面入手,分析该计划出台对实现＂国家尊重和保障人权＂宪法原则的意义。     

荀子哲学关于心的看法及其对当代大学生思想政治教育的启示——从哲学关于他心及“性恶”的角度分析

先秦时期的诸子百家对于人心都有着自己独到的看法,从儒家的性善论到法家的性恶论,都体现着他们对于他人之心的揣度。而人心的善恶也直接关系着我们应该采取何种方式来对大学生进行有效地思想政治教育。这就需要我们细致研究关于心的哲学问题,从而有针对性地开展思想政治教育工作。     

Soil and weed management for enhancing arbuscular mycorrhiza colonization of wheat

Tillage and weed control are critical components of cropping systems that need to be combined such that crops benefit from reduced competition. However, weeds may also contribute to the biological diversity within the agro‐environment. This greenhouse study investigated whether common weeds of arable cropping systems were suitable host plants for arbuscular mycorrhizal fungi (AMF), allowing the development of extraradical mycelium (ERM) that can contribute to the early colonization of a following wheat crop, especially in the absence of soil disturbance. Weeds were allowed to grow for up to 2 months before being controlled by soil disturbance or herbicide application (glyphosate or paraquat). Pregerminated wheat seeds were then planted. Chemical control of the weeds prior to sowing enhanced the early arbuscular mycorrhiza (AM) colonization rate of wheat roots, whereas mechanical disturbance was less acceptable as a method of weed control for rapid AM colonization. The type of herbicide (contact or systemic) had no impact on colonization of the wheat crop. Enhanced AM colonization promoted early P acquisition and growth of the crop. Appropriate management of weeds emerging between two consecutive cropping seasons coupled with no‐till soil management could ensure a quick and efficient AM colonization of the following wheat plants.

Research Progress on Immunoglobulin of Yolk in the Prevention and Treatment of Various Diseases

Immunoglobulin of yolk (IgY) refers to the specific antibodies from the immune eggs, is the most important immunoglobulin in the yolk,which has the characteristics of stable chemical properties, high yield, low cost, high specificity and no toxic side effects, there was no cross serological reaction among animals breeds because of a long distance. IgY has a significant advantage in animal and human disease prevention and treatment. In this research,we reviewed the application of structural characteristics, physicochemical property and action mechanism of IgY in prevention treatment of animal disease and developing prospect, especially in the treatment of animal diseases, such as diarrhea and acute treatment of animal spirit, harm, large virus disease; zoonosis seriously endanger the safety of human property; Other aspects such as aquaculture, animal fur and other major diseases. IgY could effectively prevent and treat animal diseases, but also reduce the possibility of zoonosis, which will be of great significance for the protection of personal safety.     

Research Advances in Escherichia coli K1 Penetration Across Blood-brain Barrier

E.coli K1 strain is a representative strain of neonatal sepsis and meningitis, which causes disease by blood circulation to the brain. The molecular mechanism of E.coli K1 that adhering and invading the brain microvascular endothelial cells (BMECs) and cross the blood brain barrier (BBB) has been focused on by many scholars. In this review, we focused on the gene regulation mechanisms and signaling pathway of E.coli K1 crossing the blood brain barrier to understand the molecular mechanism of the infection caused by E.coli and provide reference for prevention and treatment programs.     

人IL-1Ra基因的克隆及原核表达的研究

IL-1Ra是第一个被发现的天然存在的细胞因子拮抗剂,结合于IL-1受体后不引起IL-1效应。文章通过RT-PCR从人的胎盘组织中克隆了人IL-1Ra基因,使其在大肠杆菌DH5α中重组表达。结果表明,克隆到了460bp左右的目的基因,并在大肠杆菌中成功表达了18ku左右的目的蛋白,目的蛋白在大肠杆菌中表达量占总蛋白20%左右,为IL-1Ra的进一步研究及应用奠定了基础。     

海洋食物网结构稳定性及干扰响应研究综述

针对当前全球环境急剧变化的背景,本文归纳了海洋食物网结构复杂性常用的量化指标,梳理了食物网稳定性不同维度的概念并深入探究其与复杂性之间的内在联系。根据海洋生态系统的不同干扰类型,分析了各种类型干扰的发生方式以及食物网在应对干扰时的适应机理,最后总结了海洋生态系统数据获取分析以及食物网构建时有待解决的问题,并指出开展初级生产者与消费者之间的相互作用研究能更利于解析全球变化对海洋食物网结构和功能的影响。
