The impact of sea level rise on the law of the sea and the protection of China＇s rights and interests in South China Sea

＂陆地统治海洋＂及＂基线决定国家管辖海域范围＂是目前国际海洋法的两大基本原则,然海平面上升不仅可使岛屿向岩礁甚至低潮高地退化,也会致使低海拔国家的沿海基线具有不确定性,引发了人们对于其可能导致的国家管辖海域范围外部界限及相邻或相向国家海域划界协议变化的担忧。由于南海独特的地理环境、复杂的领域主权纠纷以及尚未公布南沙群岛基线等特征,在海平面上升所引发的相关海洋法问题上,保护中国南海权益显得尤为迫切。中国应当通过促进包括条约法和习惯法在内的海洋法发展以维护南海权益,探索这一问题的解决方式不仅有利于维护中国的南海权益,也将助力于国际法治发展。＂The land dominates the sea＂and＂baselines determine the boundary of sea areas under national jurisdiction＂are two of the basic principles under the international law of the sea. The rise in sea level due to climate change not only downgrades an island to a rock/reef or even to a low-tide elevation,but also leads to uncertainty on the coastal baselines of low-lying countries. This has raised concerns about the possible changes in the outer limits of sea areas under national jurisdiction or in the maritime delimitation agreements between States with opposite or adjacent coasts. The law-of-the-sea issues caused by sea level rise have become pressing in South China Sea because of its particular geological environment,the complicated disputes over territorial sovereignty and unpublished baselines in Nansha Islands et al. China should promote the development of the law of the sea,including treaties and customary law,with a view to safeguarding its SCS rights and interests. Seeking for solutions to these issues would not only be conducive to the protection of China＇s SCS rights and interests,but also to the development of international rule of law.国家社科基金重大项目“我国南海岛礁所涉重大现实问题及其对策研究”（16ZDA073

A Study on the mechanisms of eutrophication of a shallow upstream lake in the Jiulong River Catchment

基于对九龙江上游龙潭湖富营养化水体和沉积物现状的监测结果,通过与国内富营养化深水湖库和流域下游大型富营养化浅水湖泊进行对比,深入探讨了流域上游浅水湖泊富营养化发生的原因及主导机制.流域上游浅水湖泊具有外源污染物输入较少的特点,较下游大型浅水湖泊更易受温度等气候条件和沉积物氧化还原状态的影响,以及外源输入总磷控制具有较强的滞后效应,因此对流域上游浅水湖泊富营养化的控制必须重视内源营养盐释放,特别是结合态磷的内源释放问题.Based on site monitoring chemical data of lake water and sediments during an algal bloom in the Longtan Lake,causes and mechanisms of eutrophication in shallow upstream lakes were discussed by comparing the Longtan Lake in upstream of the Jiulong River with deep eutrophic lakes and large shallow downstream eutrophic lakes in China.The shallow upstream lake is characterized as relatively simple nutrient inputs and high susceptivity to climatic variability(such as temperature),redox conditions,and strong lag effects of the external total phosphorus inputs.Therefore,attention must be paid to the sediments nutrient releases,especially,the bound phosphorus of sediments when remediating eutrophication in shallow upstream lakes.国家自然科学基金资助项目(41175130);教育部新世纪优秀人才支持计

Studied the difference of genetic feature between tissue cultured and cultivated paddy rice of Jia He Zao Zan via microsatellite(SSR) markers

株高是水稻重要的农艺形状之一,植株过高将导致倒伏和减产,目前,很多新的技术究被用来鉴定,图位克隆与水稻株高相关的基因及机理的研究,本实验选择优质早籼稻佳禾早占种植苗和经过组培获得的矮化突变水稻为材料,为研究比较它们间的遗传物质上差异,根据康耐尔大学的资料设计了311对SSR引物对佳禾早占种植材料和组培材料进行分析,对两种材料进行PCR多态性扩增,结果发现两者间存在多态性的引物有88对,多态性比例达到30.3%。在矮杆材料中不但验证了已报道的11个与调控株高性状基因相连锁的标记连锁群,同时在第3号染色体和第9号染色体上还获得了两个以前基本未有报道的标记集中分布区域。结果说明,该培养基培育出的佳禾早占水稻后代所表现出的矮杆性状与亲本在遗传物质上确有明显差别。该结果有助于挖掘和定位新的矮杆基因,并有利于今后在水稻育种中进行水稻株高性状的控制,同时也为开展矮化性状机理的研究提供有利的实验材料。Plant height is one of the important agronomic traits of rice.Overhigh plant easily led to lodge and reduce output.Recently,great advances have been made in the identification,mapping,cloning and action mechanism of plant height genes in rice.This present paper selected the tissue cultured and cultivated paddy rice of Jia He Zao Zan(J.H.Z.Z) as experimental object,which were significant different on the height,the tissue cultured plant was only less than half height of the cultivated plant.In order to compare their differences of genetic and determine whether there are relationship between the dwarf gene and the dwarf character of tissue cultured plant,Polymorphism analysis was conducted between them by 311 pairs of rice SSR primers,designed by Cornell University,the result indicated that 88 pairs of primers had polymorphism between two kinds of materials,the ration in total primers was about 30.3%,the experimental result not only verified 11 multiple groups which regulate the height gene,but also obtained two group regions which control the dwarf character on chromosome 3 and chromosome 9,which have not been reported previously,these results will help to explore and determine the situation of new dwarf gene,and will be of benefit to act genetic manipulation of plant height of in rice breeding.These results also provided the evidence for studying the mechanism of dwarf.国家863项目(2002AA211091),(20001AA11091);; 厦门大学细胞生物学和肿瘤细胞工程教育部重点实验室开放基金资助(NO:2005108)资

SARS-CoV N蛋白与人冠状病毒HCoV-OC43和HCoV-229E的交叉反应表位及特异表位的确定

为确定SARS-CoV N蛋白的特异抗原表位,对3种人冠状病毒SARS-CoV、HCoV-OC43和HCoV-229E N蛋白之间的交叉免疫反应进行了系统研究。构建了分别表达SARS-CoV、HCoV-OC43和HCoV-229E N蛋白的重组痘苗病毒,并制备了相应的小鼠免疫血清。用间接免疫荧光方法,检测了3种N蛋白的表达及其与3种冠状病毒免疫动物血清和SARS病人恢复期血清之间的反应。与此同时,用Western blot方法分析了原核表达的39个不同区段的SARS-CoV N蛋白与3种冠状病毒动物免疫血清和SARS病人恢复期血清之间的交叉反应性。免疫荧光检测结果表明,SARS-CoV、HCoV-OC43和HCoV-229E3种病毒的N蛋白在重组痘苗病毒感染的HeLa细胞中均可以特异表达;3种N蛋白之间存在明显交叉免疫反应。Western blot结果显示,SARS-CoV N蛋白的表位主要位于30~60aa、170~184aa、301~320aa和360~422aa;与HCoV-OC43的交叉反应表位主要位于30~60aa、90~120aa、204~214aa和320~360aa;与HCoV-229E的交叉反应表位主要位于30~60aa、150~160aa和301~360aa。含SARS-CoV N蛋白特异表位的重组肽N155b(60~214aa)和N185(30~214aa)只与SARS病人恢复期血清和灭活SARS-CoV免疫小鼠的血清反应,而不与灭活HCoV-OC43和HCoV-229E免疫的山羊血清产生交叉反应。上述结果为使用SARS-CoV N蛋白抗原进行特异诊断试剂的研究,提供了重要的实验依据

表观遗传修饰在应激诱发抑郁症中的作用

应激可以对个体的生理和行为产生负面影响,甚至导致抑郁症,但病因机制尚不清楚。近年来许多研究发现应激导致的表观遗传修饰变化影响抑郁症的发生。表观遗传是指DNA序列不发生变化,但基因表达却发生了可遗传的改变。应激引起的HPA轴、单胺类递质、BDNF三个方面的表观遗传修饰的变化,在抑郁症发生中发挥重要作用。最后提出了目前表观遗传机制研究的局限性和未来研究热点
