查询词典 columella

Longitudinal root sections of the wild type and the gls mutant cultured in nutrient solution for 4 days showed that biosynthesis and distribution of amyloplast in the columella cells of gls were normal as compared with the wild type, suggesting that root gravitropism loss in gls mutant is not caused by the defect in amyloplast sedimentation, but possibly by the disturbance of auxin transport and distributation.

4天龄的根系纵切片结果显示：突变体gls根尖结构完整，根尖柱细胞内淀粉粒的生成和分布正常，表明gls突变体根系向地性的缺失不是由于淀粉体的原因，而可能通过影响生长素运输和分布造成。

结果表明：两受体基因的表达在番茄果实成熟进程中变化不明显，LeETR4在同一时期的果实外果皮中表达水平低于其在辐射壁和中柱的表达。

After the biomechanical finite element analysis for the three-dimensional reconstruction model, we find the structure of the deformed nose showes the following characteristics: 1, Nasal septum, nasal columella, lateral feet of nasal alar, lateral nasal dorsum are stress concentrated regions, that is the key mechanical positions of deformed nose; 2, Under the static state, nasal deformation has a very small value of stress distribution, under displacement load status, the deformed nasal has a large value of the stress distribution; 3, Ipsilateral nasal columella are the the key mechanical parts of deformed nasal rectify. And lateral nasal alar is also the most stress concentrated areas.

对于重建后的单侧唇裂鼻畸形鼻部模型进行有限元生物力学研究，发现畸形鼻的力学结构呈现以下特点：1、鼻中隔、鼻小柱、鼻翼外侧脚、鼻背外侧是单侧唇裂鼻畸形应力分布的集中部位，也就是畸形鼻部的力学关键部位；2、在静态状态下，畸形鼻部拥有的应力分布值很小，在位移载荷状态下，形变后的畸形鼻部拥有的较大的应力分布值；3、单侧唇裂鼻畸形整复中，鼻小柱患侧部是畸形整复的力学关键部位，其次就是患侧鼻翼部。

The "V-Y" progradation suture was used in the philtrum introcession and the bottom of nasal columella to extend the nasal columella.

在鼻小柱底部人中凹陷处行"V-Y"皮瓣推进缝合以延长鼻小柱。

It suggested that under static status, the nasal septum, nasal columella and the lateral feet of nasal alar were the most concentrated areas of stress distribution. They are key mechanical parts of deformed nasal.3.2 Nasal displacement load analysis of patients with unilateral cleft lip and nasal alar collapse Deformed nasal displacement load three-dimensional finite element analysis showed that if the ipsilateral and contralateral nasal parts obtain similar geometry, the positions around nasal columella in ipsilateral nostril were the most stress concentrated region, next parts were the nasal septum and the lateral nasal alar.

提示静态状态下，鼻中隔、鼻小柱和两侧鼻翼外侧角是应力分布最集中部位，也是畸形鼻部的关键力学部位。3.2单侧唇裂鼻翼塌陷畸形患者的鼻部位移载荷形变后力学分析单侧唇裂鼻畸形患者的位移载荷三维有限元分析表明，畸形鼻部的患侧要获得和健侧近似的几何形态，其患侧鼻孔近鼻小柱周围应力分布最为集中，其次为鼻中隔和患侧鼻翼外方。

Scar resection in upper lip, orbicularis oris muscle reconstruction, Z-plasty, V-Y plasty or double movable mucomuscular complex flaps for vermilion defects were applied to slight nasolabial deformities. In severe labionasal deformities, Forked flap was used at the upper lip to lengthen columella for patients who have enough upper lip tissue, while for those who have deficient upper lip tissue, the prolabium was advanced into columella for lengthening and an Abbé flap was adopted for upper lip reconstruction. Results Since 2000, we have treated 23 patients of secondary deformities of bilateral cleft lip.

对上唇及鼻畸形较轻者，采用上唇瘢痕切除，口轮匝肌重建，V-Y成形、Z成形术或双侧肌蒂红唇肌粘膜瓣向中间推进矫正红唇口哨畸形；对唇鼻畸形较严重但上唇组织较多者，采用鼻底叉形瓣延长鼻小柱进行矫治；对唇鼻畸形严重并有上唇过紧者，采用前唇组织瓣延长鼻小柱，下唇带蒂组织瓣旋转修复上唇正中缺损。

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。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。
