Methods we developed a surgical technique to correct short nose by increase tissue volume in nasal tip ,nasal alae and the columella. The technique contain three steps:① Wide dissection and prolongation of the outer skin envelope to cover the lengthened framework by a "V" formed surgical approach from columellar base to inner edge of alae.②Silicone or expanded polytetrafluoroethylene implant is used to correct saddle nose and to length nasal framework.③A papilionaceous concha composite graft containing a elliptic ear cartilage and a onlay "V" formed skin and subcutaneous tissue is grafted to inner edge of columella and alae. Results we performed the procedure on 8 patients.

通过8例短鼻缺陷受术者采用蝶形复合耳郭组织游离移植到鼻尖鼻翼以增加鼻尖鼻翼的组织量以达到延长短鼻的目的，手术分为三个步骤：首先从鼻小柱基底到两侧鼻翼内缘做V形切口，广泛分离鼻尾端皮肤粘膜；然后，通过硅胶或ePTFE假体材料间插并缝合于两侧大翼软骨之间延长鼻尖部软骨支架；最后，将蝶形耳后复合组织块移植到切口部以增加鼻尖鼻翼部的组织量，术后观察该法延长短鼻的实际效果。

Chromosome pairing behavior in meiosis of the hybrid F1 was carried out. Results showed that in an average , 1.25 rod bivalents were observed in one PMC, meiotic configuration was 2n=14=11.49Ⅰ+1.25Ⅱ(Xta=1.25) and most of PMCs possessed 1～5 bivalens, indicating that the relatively high homeology was detected between the D genome of Ae.tauschii and the V genome of D.villosum. The morphological differences between F1 hybrids and their parents were significant. F1 plants were highly self-sterile, but partially self-fertile after treated by chromosome doubling technique.

对杂种F1花粉母细胞减数分裂中期Ⅰ染色体配对行为进行观察发现，"节节麦×簇毛麦"杂种F1平均每PMC有1.25个棒状二价体，染色体的平均构型为2n=14=11.49Ⅰ+1.25Ⅱ(Xta=1.25)，大部分被观察的细胞出现1～5个二价体，表明节节麦D染色体与簇毛麦V染色体间具有相对较高的部分同源配对， D和V染色体之间存在一定的部分同源性。F1植株高度自交不育，经染色体加倍处理后能够自交结实。
