Three major clusters of numt sequences ( cyt b numt、 ATP8+ATP6 numt and ND4+ tRNA-His+ tRNA-Ser numt) were particularity amplified and sequenced from 10 species within Galliformes and A.galericalata. Comparison numts sequences with homologous mitochondrial partial genes get the different evolutionary characteristics and evolutionary speed compared to mtDNA, then examine the age of insertion of numts using the sequence divergence of numt from the mtDNA. Finally, joined Coturnix japonica、 Coturnix chinensis、 Lophura leucomelana、 Lophura swinhoii and A.albifrons mitochondrial sequences in GenBank, we study the importance function to phylogenetic research of mitochondrial genes and homologous numts.The evolutionary rate of Numts is lower than their authentic sequences of mtDNA, cyt b and ND4 gene evolve faster than homologous numts 2.5 times; ATP8+ATP6 gene evolve faster than numts 18.9 times in Galliformes. Numts show less codon position bias and transition bias under not phylogenetic pressure.

根据2004年3月GenBank登录的红原鸡核基因组草图与其线粒体基因组比对发现红原鸡核基因组中存在3段较长的线粒体假基因，利用PCR方法扩增鸡形目10种鸟类和雁形目中鸳鸯核基因组中3段numt序列：cyt b numt、ATP8及下游ATP6 numt和ND4+tRNA-His+tRNA-Ser numt，测序后分别比较线粒体基因与核同源numt序列的进化特点和进化速率，确定numt序列插入核基因组的时间，以及结合GenBank已登录的日本鹌鹑、蓝胸鹑、黑鹇、蓝鹇和1个雁形目物种——白鹅雁(A.albifrons)相应序列探讨两种同源序列对于鸟类系统进化发育重建的重要作用。

Construction of the homologous arms directing the homologous recombination For the sake of seeking for the more efficient integrating strategy to make the foreign gene insert in the specific site and don't destroy the host expressional and regulatory elements such as promoters and introns, we experimented targeting the Bombyx morl fibroin heavy-chain exon II with the green fluorescent protein gene by homologous recombination technology.

为了探索一条更为有效的整合策略，使外源基因能定点整合到靶位点，又不破坏宿主基因的启动子、内含子等表达调控元件，令外源基因对宿主生理功能的影响达到最小，我们以丝素重链基因2号外显子为整合靶位点，以便将外源基因定点整合其间。

The results showed that (1) all the arteries tested had tachyphylaxis to peptidergic agonists;(2) the desensitization of the arteries tested to catecholamines was uneasy except BA;(3) the desensitizations to AⅡ, AVP and PE were homologous;(4) the endothelium-EDRF -cGMP pathway had no contribution to the tachyphylaxis of PA to AⅡ and AVP;(5) membrane receptor cycling (internaliation and re-insertion) contributed only in part to homologous desensitization;(6) there was no change in the function of voltage-dependent Ca〓 channel during desensitization to AⅡ and AVP;(7) some changes in G protein occurred during homologous desensitization;(8) the most surprising finding was that the caudal arterial smooth muscle of stroke-prone spontaneously hypertensive rat showed tachyphylaxis to α〓-adrenoceptor agonist PE, while the tachyphylaxis of pulmonary artery of SHR was not changed compared with that of Wistar rat.

脱敏是消除效应的一种有效方式。因此，研究不同血管对不同激动剂脱敏的差异及阐明脱敏的机制，有助于阐明血管活动个性化的机制。研究表明：血管对肽类激动剂的脱敏方式为快速脱敏，而对儿茶酚胺类激动剂不易脱敏；血管对肽类激动剂和儿茶酚胺类激动剂表现为同源脱敏；内皮-NO-cGMP通路不参与肺动脉对AⅡ和AVP的快速脱敏；用PAO抑制膜受体的内在化只能短暂抑制脱敏的发展，提示用膜受体数目的下调说不能完全解释同源脱敏；血管对AⅡ和AVP脱敏后VSMC细胞膜电压依赖性钙通道功能无改变；CA对AVP脱敏后GTPγS的量-效曲线下移，说明有G蛋白的变化，但这种变化并非G蛋白的亲和性改变；SHRsp之CA平滑肌对AⅡ和AVP的快速脱敏并未减弱，但对PE却表现为快速脱敏，这是我们首次发现的一个非常有趣的现象。
