objectiveto evaluate the result of using rectangular advacement flaps for repairing the eyelid defects at the edges of palpebra.methodswe have used rectangular or double rectangular advacement flaps to repair the defects of theantieror margin of eyelid in 36 cases.to repair the posterior margin defects ,when the defects of thetarsal plates were shorter than 5mm,the tarsal plates were closed directly , longer than 5mm ,sliding tarsal palpebral conjunctive flaps were to be used.resultsin 36 cases all of the flaps were survived with primary healing, slight scar, no absence of eyelashes, no notch deformity at the edge of palpebra, no trichiasis.

目的：探讨应用矩形推进皮瓣修复睑缘眼睑缺损的效果。方法：对36例睑缘肿物切除的眼睑缺损患者，采用矩形或双矩形推进皮瓣修复眼睑前层缺损。眼睑后层睑板缺损小于5mm者，采用直接缝合法；睑板缺损大于5mm者，采用睑板睑结膜瓣移行法。结果：36例患者皮瓣全部成活，切口ⅰ期愈合，手术瘢痕轻微﹑睫毛无缺失﹑无倒睫﹑睑缘圆滑无切迹畸形。

According to the materials and purpose, differential presser foot 、 needle gauge 、 single cutter or double cutter are optional.

带有切边与分线功能，可根据不同的材料和缝纫目的选择不同的压脚、针、单刀还是双刀。

In order to clone the VIP gene in the gastrointestinal tract from beijing duck, one pair of specific primers to VIP gene was designed and synthesized according to the chick sequence (X80906). Encoding VIP cDNA fragments were amplified by RT-PCR from the total RNA in the Proventriculus, the Duodenum and the Jejunum of Beijing duck. Their PCR products were ligated into pGEM-T easy vector, which was transformed into E. coil JM109. Positive bacteria clones were screened and identified by PCR method and digested with the double restriction enzyme EcoRⅠ. The sequence of VIP gene fragment was also determined and analyzed.

为从北京鸭胃肠道中扩增血管活性肠肽基因，根据鸡VIP基因（GenBank登录号X80906），设计了一对简并引物，从北京鸭腺胃、十二指肠和空肠提取总RNA，通过反转录－聚合酶链反应扩增，将从腺胃、十二指肠和空肠中扩增出的产物克隆到pGEM-Teasy载体上，导入大肠杆菌JM109，阳性克隆经双酶切鉴定后测序，将测序结果与鸡和鹅（GenBank登录号为DQ023161）的VIP基因进行同源性比较。
