Vascular hyperpermeability is one of the important causein hypovole-mia and organs disfunction after various kinds of shock,and its treatment is still one of the problems in the medical field. For example,the operative methods of preventing hyperpermeability and plasm bleeding is still unreliable after severity burn,and traditional treatment just passively transfuses according to the burn clysis formula instead of inhibiting permeability by injecting drugs. The principal reason is that pathogenesis of vascular endothelial cell permeabilty has not been entirely revealed at the level of molecular biology.

血管通透性增高是休克时有效血容量减少和器官功能损害的重要原因之一，它的防治一直是医学界的一个难题，如在大面积烧伤时，至今未能找到一个简单有效的防治血管通透性升高和血浆渗出丢失的方法，传统的方法只是根据烧伤补液公式测算进行被动的补液来纠正，而不能依靠注射化学制剂来终止其渗出，主要原因是未能从分子生物学水平揭示血管内皮细胞渗出的机制。

Homology modeling of 3-D structure of two AChE from L.entomophila were constructed using H.sapiens(1p0i:A) native BuChE structure and Drosophila melanogaster(1d×4:A) native AChE structure as templates,respectively,by SWISS-MODEL.The catalytic triad were found and denoted in the 3-D structure of AChE from L. entomophila referring to T.californica.2.2 Gene cloning ofβ-actin and mRNA expression levels of two AChE genes from L. entomophilaBecause no reference gene has ever been used in Real Time PCR for L.entomophila in GeneBank,a fragment ofβ-actin gene was cloned from L.entomophila(GenBank Accession No.: FJ041117).It consists of 822 bp encoding a protein of 273 amino acids residues.

利用蛋白质结构同源建模工具，分别以人丁酰胆碱酯酶(1p0i：A)和果蝇乙酰胆碱酯酶(1d×4：A)的蛋白晶体结构为模板，对嗜虫书虱2个AChE的三维结构进行同源建模，并在三维结构中发现了AChE的酶解活性位点，证明嗜虫书虱体内也存在2个AChE基因。2.2嗜虫书虱β-actin基因克隆及乙酰胆碱酯酶基因mRNA表达水平研究目前关于嗜虫书虱的分子生物学研究较少，在GenBank中没有可用作内参基因的序列，因此本研究从嗜虫书虱体内克隆获得β—actin基因片段(GenBank登录号：FJ041117)，该片段长度为822 bp，编码273个氨基酸残基，同源性比对分析表明该片段与其它昆虫的β—actin基因具有很高的同源性。

2N gametes are the result of meiotic mutation during micro- and mega-sporogenesis that bear the sporophytic rather than the gametophytic chromosome number. This paper reviewed the genetic markers including the morphologic, cytological, isozymes and DNA markers, which have been employed in the generation, inheritance, heterozygosity and marker-assisted breeding of 2n gametes based on the frequency of large pollen grains, cytological analyses, unexpected occurrence of polyploidy progeny and the associations between parents and progenies.
