哺乳动物的大脑是一个由神经元、神经胶质细胞和超过1.1.1.个突触组成的复杂的器官。神经元是一组异质的电活性细胞，形成大脑复杂电回路的框架。然而，神经胶质细胞约占哺乳动物中枢神经系统(CNS)所有神经细胞的一半，主要分为星形胶质细胞、小胶质细胞、少突胶质细胞(OL)和少突胶质细胞前体细胞(OPC)；神经胶质细胞主要为大脑中的神经元提供营养支持。近二十年来，“三联突触”的概念引起了广泛关注，该概念强调星形胶质细胞是突触的组成部分，并在接受神经元信号后以反馈方式调节神经元活动。自此，神经胶质细胞的突触调节得到了广泛的研究和实质性的修改。本综述总结了关于神经胶质细胞(特别是小胶质细胞和OL谱系细胞)如何影响和重塑大脑突触结构和功能的最新重要发现。我们的综述强调了神经元-神经胶质细胞串扰的细胞和分子方面，并提供了有关神经元和神经胶质细胞之间的异常突触通讯如何导致神经病理学的额外信息。

地球关键带是人类生存和发展的关键区域。关键带发生的一系列物理、化学和生物过程与人类活动密切相关。土壤水分是黄土高原关键带的关键要素,同时又是黄土高原植被恢复与生态环境重建的决定因子。为揭示黄土高原关键带土壤水分的空间分异特征,采用网格（50m×50m）布点,雨季结束后采集0~500cm深度土壤样品,结合室内分析,结果表明：黄土高原小流域中73个样点0~500cm的土壤含水量分布范围介于1.~23%之间,降水对0~1.0cm土层的土壤水分补充明显;土壤水分在水平和垂直方向都表现出明显的空间异质性,在不同方向上的水分控制过程有所不同,是对土地利用方式、植被类型、地形要素、土壤质地等多因素综合响应的结果。充分理解关键带土壤水分空间的分异规律及其主控因素有助于该区小流域综合治理中的植被建造与布局,也有助于对该区土壤水文和生物地球化学过程的理解。

[Objectives] The research aimed to explore extraction method of Oenanthe benghalensis polysaccharide,and determine the optimal process of its ultrasonic extraction by orthogonal test. [Methods] Phenol-sulfuric acid method was used to determine polysaccharide's content. Based on single-factor experiment and orthogonal test,the influences of solid-liquid ratio( A),ultrasonic extraction temperature( B),ultrasonic power( C) and ultrasonic time( D) on extraction rate of O. benghalensis polysaccharide were studied,and the optimal process of ultrasonic extraction was selected. [Results] The influence order of solid-liquid ratio( A),ultrasonic extraction temperature( B),ultrasonic power( C) and ultrasonic time( D) on extraction rate of O. benghalensis polysaccharide was A > D > B > C. Via the orthogonal test,it was determined that the optimal extraction condition of O. benghalensis polysaccharide was as below: solid-liquid ratio 1. 25( g/mL),extraction temperature 60℃,extraction power 80 W,extraction time 40 min. Under the condition,extraction rate of O. benghalensis polysaccharide was9. 80%. [Conclusions] The process could provide the reference basis for extracting and producing O. benghalensis polysaccharides.

陕西佛坪国家级保护区是我国重要的自然保护区之一,包括大熊猫、金丝猴在内的很多珍稀濒危物种分布其中。20世纪90年代后期,全国林业开始实施"天然林保护工程",这对佛坪保护区当地的农业、工业、经济发展和生活质量产生了很大的影响。为了探究"天然林保护工程"对野生川金丝猴的保护产生何种影响,我们于201.年至201.年采用访问调查和实地踏查方法对佛坪保护区20世纪90年代至今的川金丝猴种群动态变化进行研究,结果发现不论是种群数量(从少于500只增至671.左右)还是栖息地面积(从1.7.8 km^2增至236.5 km^2)都明显增长;家域范围随着年代的推移向低海拔位置扩大(秋季平均海拔为1.680 m±304 m),越来越靠近人类;川金丝猴在家域范围内,对常绿阔叶林和落叶阔叶林有明显的选择偏好,活动比例分别达到了40.1.%和38.41.。实施"天然林保护工程"后,当地农业开发和经济活动在逐渐转型,减少了人类活动对野生动物栖息地的干扰,提升了栖息地保护的质量和生态环境。因此,此项工程的实施在该地区川金丝猴保护方面表现出积极的效果,促进了当地金丝猴栖息地的改善,种群数量得以增加扩大,是一个野生动物保护的成功案例。

哺乳动物的大脑是一个由神经元、神经胶质细胞和超过1.1.1.个突触组成的复杂的器官。神经元是一组异质的电活性细胞,形成大脑复杂电回路的框架。然而,神经胶质细胞约占哺乳动物中枢神经系统(CNS)所有神经细胞的一半,主要分为星形胶质细胞、小胶质细胞、少突胶质细胞(OL)和少突胶质细胞前体细胞(OPC);神经胶质细胞主要为大脑中的神经元提供营养支持。近二十年来,“三联突触”的概念引起了广泛关注,该概念强调星形胶质细胞是突触的组成部分,并在接受神经元信号后以反馈方式调节神经元活动。自此,神经胶质细胞的突触调节得到了广泛的研究和实质性的修改。本综述总结了关于神经胶质细胞(特别是小胶质细胞和OL谱系细胞)如何影响和重塑大脑突触结构和功能的最新重要发现。我们的综述强调了神经元-神经胶质细胞串扰的细胞和分子方面,并提供了有关神经元和神经胶质细胞之间的异常突触通讯如何导致神经病理学的额外信息。
