Today,correct diagnosis of CAEBV and studying its pathogenesis are two hot researching points.But in the diagnosis process,we found the antibodies of CAEBV presenting diversity,which did not coincidence with the detect of EBV-DNA.Some CAEBV patients lack the elevation of the EBV antibodies if its immunoglobulin was low or had sthenic spleen function,but their EBV-DNA copies increased dramatically.Those having high EBV antibodies may be caused by the cross-reaction of other factors.

最初的关于CAEBV患儿的报道始于二十世纪八十年代初，CAEBV感染主要发生在小儿，而成年以后很少发病；CAEBV感染在亚洲发病率高，随访8月至12年死亡率43%，而且与多种临床疾病，特别是与EBV相关的T、NK淋巴细胞增殖综合征、噬血细胞性淋巴组织细胞增生症和恶性淋巴瘤等预后不良的疾病密切相关，所以CAEBV越来越受到研究者们的关注。

Aim-teaching, which originates from the 80s to 90s in the beginning of the last century, is a kind of teaching mode that developed by Chinese pedagog on the basis of American educator Tyler's "Principles of Make Curriculum" and his student-Broome's "Educational Target Taxology".

The clearer the West's displeasure, the better the chances ofgetting peacekeepers and monitors from other countries into Abkhaziaand South Ossetia to replace the Russian troops which have been thereas peacekeepers since the early 1990s, but which should leave as theyare now clearly occupying forces.

西方越清楚地表达其不满，其他国家的维和部队和观察员就越有可能进入阿布哈兹和南奥塞梯，以取代上世纪90年代初就作为维和部队进驻在那里的俄罗斯军队。俄罗斯军队应该离开那里，他们的行为已经是明显的武装占领。

As MEMS (Micro Electro-Mechanical Systems) technology progresses rapidly, the synergism between MEMS and biomedical technology becomes closer than ever before. When the uTAS was introduced in the last two decades, many microfluidic chips, microelectrodes, and microreactors are being studied for drug detection, environment detection, gene analysis etc. Due to its small volume, low pollution, low consumable and good portability, uTAS plays a very important role in biomedical, biochemical, environment engineering fields.

随着MEMS(Micro Electro-Mechanical System，微机电系统)制造技术的不断发展，生物医学与其之间的联系越来越紧密，自上世纪90年代初提出uTAS(Micro Total Analysis System，微全分析系统)之后，各种各样的微流控芯片、微反应器、微电极、微分离器等便大量涌现，广泛应用于药物检测、环境监测、基因分析等诸多领域中，并且由于其试剂消耗量少、检测效率高、环境污染小、体积小、易于携带等优点，在生物医学、化学、环境工程等领域受到越来越多的重视。
