This subset is hyporesponsive and anergic to antigen stimulation. Recently, it has been demonstrated to participate in the immune deficiency in human immunodeficiency virus infection and has close relationship with the development of acquired immunodeficiency syndrome. Meanwhile, the CD4(superscript +)D25(superscript +)Treg is also infected when the human body is invaded by HIV. The CD4(superscript +)CD25(superscript +)Treg will finally be killed by the mechanism of antibody-dependent cell-mediated cytotoxicity. Because of the decrease of the CD4(superscript +)CD25(superscript +)Treg, it can't function as a immune suppressor as a result of the excess of activation of HIV and gradually exhausting of the T cell, which shows that the CD4(superscript +)CD25(superscript +)Treg plays a inhibitory role in the different stages of the development of the HIV as well as different effects in the pathogenesis of AIDS.

它能够抑制自身免疫病的发生和发展，参与肿瘤免疫的调节，同时在感染和移植免疫中也发挥着极其重要的作用。T细胞的这一亚群具有免疫调节和免疫抑制的特性，新近发现它亦与爱滋病的发生、发展关系密切HIV进入人体后，CD4D25调节性T细胞抑制了机体的免疫效应但它也同时被感染，最终由于细胞毒的作用而死亡由于调节性T细胞数量的减少不能有效的发挥其抑制作用，HIV持续的过度活化使得T细胞逐渐耗竭说明在HIV发生、发展的不同阶段Treg细胞可能都发挥了免疫抑制作用，但是却对HIV感染与爱滋病发病的进程产生了不同的效应。

People would not expose and criticize various evil and illegal events by means of mass media. These will connive at those behaviours which infringe the right of personality of citizens, and in the meantime, will degrade the right of personality to absolute extreme individualism. On the contrary, if the law sufficiently protect the media supervision while ignore the protection of the right of personality, the right of media supervision is likely to be abused."Right without restriction definitely leads to corruption." And the right of media supervision is no exception, otherwise it will probably be abused and cause corruption. As Mr. Xu Chunguang has said, media supervision is like a double-bladed sword.

人们对社会生活中出现的各种丑陋和违法现象，不能借助于大众传播工具予以大胆披露和批评，这不仅会纵容一些侵害公民权利包括侵害公民人格权的行为，而且会使个人的人格权沦为一种与社会利益不协调的绝对化的极端个人主义；反过来，如果法律仅对舆论监督予以充分保护而忽略了人格权的保护，那么，就会导致舆论监督权的滥用，&不受约束的权力必然会产生腐败&，舆论监督权也不例外，否则，舆论监督权就可能被滥用，滋生腐败。

According to the domain organization, the GGDEF-EAL containing proteins (pfam database, version 17.0) were classified into A and B types. Six hundreds and five of the 621 proteins were in A type, which was also found in the ancient bacteria Aquifex aeolicus VF5 suggesting that this is the ancestor of the GGDEF-EAL proteins. Phylogenetic analysis of GGDEF- and EAL- containing proteins in the genome of V. vulnificus YJ016 revealed that GGDEF-EAL proteins were clustered. Comparative analysis of domain organization of the clads in the EAL tree allowed identification of several duplication events. The results indicated that most of the GGDEF- and EAL- containing proteins arised by gene duplication.

根据pfam资料库(Version 17.0)，我们整理同时拥有GGDEF和EAL功能性区域的蛋白质，这些蛋白质可以被区分成两种型态，在总数621个GGDEF-EAL中有高达606个是A型态，而且它在古老的细菌Aquifex aeolicus VF5的基因体中也能找到，因此我们推测它可能是GGDEF-EAL的袓先，藉由分析创伤弧菌中所包含之GGDEF和EAL的演化关系，大部份的GGDEF-EAL会群聚在树型相近的位置，进一步比较在EAL树型上有邻近关系的蛋白质序列，根据他们的长度、与所包含的功能区域，我们找到了一些重制的演化痕迹，这样的结果指出，目前看到大多数的GGDEF 和EAL可能都是经过重制产生。

Hou uses a retrospective and reflective attitude in making this movie, scripting this historical incident to happen to a normal family, so that the story can be dealt with more rationally. On the other hand, he purposely posed Wenqing, the protagonist in the movie, as a mute. The protagonist being a mute seems to bring about a great restriction to the development of the story, but from another point of view, it actually maximizes the artistic potential of the movie. Visual footages were being presented continuously, and with the various incomplete images being pieced up gradually, it presents Wenqing's world to the viewers in an even clearer light.

导演以一种追忆和反思的姿态面对摄影机介入在已经流逝的时空里演绎一段历史事件在台湾平民家族所发生的故事以一种更为理性的态度去面对和思考电影本身的含义，却偏偏安排了文清，一个哑巴作为整个故事的主角，将电影化的手法扩大到最大，不能说话让故事的进行产生了很大的限制，在另一个角度来看却是将艺术的能量最大空间的给予了发挥的可能性，视觉资源被不断地挖掘，给了看的内容和条件，让人事物的原初画面在断裂的片断中慢慢的连接起来，残象贯穿正是让文清的世界变得更加的明朗化。

Volcanic rocks shaped by a volcanic movement tend to occur vugs and fissures as spaces for hydrocarbon storage during rapid magma condensation;the volcanic debris deposits are characterized by expanding and dispersing in water,being either favorable to packing pores,and becoming good sealing caps,or to preservation of oil/ga...

火山活动形成的火山岩，在岩浆迅速冷凝过程中会产生孔洞和缝隙，成为容留油气的空间；火山活动形成的火山灰沉积，具有遇水膨胀和分散的特点，地层孔隙被其它充填后而成为良好的封存盖层并能抗御新构造运动的破坏而有利于油气田的保存；火山活动提供1020～1200℃的岩浆和300～400℃的热液流体携带的热能，为油气运移提供热动力条件，促进油气运移；火山活动在沉积盆地内形成的火山岩体与侵入岩体，为含油气盆地增加了一种非构造圈闭———火山岩岩性圈闭。
