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。

Results: Main CT appearances of this group of cases:①Ampullary carcinoma manifested as a small mass and was prone to protruding into duodenum, whereas the center of pancreatic head carcinoma was located in pancreas.

结果：本组病例的CT主要表现：①壶腹癌瘤体小，易向十二指肠腔突出，中心位于十二指肠腔内；胰头癌的中心则通常在胰腺内。

METHODS: The clinical data of 326 patients received choledochoduodenostomy from 1962 to 2002 were analyzed respectively.

目的：总结胆总管十二指肠吻合术的远期疗效方法：回顾性分析1962-2002年胆总管十二指肠吻合术326例的临床资料。

Results The morphology of endocrine cells in digestive tract was of multiplicity.The density of 5-HT cells was the highest in the colon,but not found in the esophagus,cardia gastric and cecum.The results showed that SS cells were distributed in the pylorus mostly,but not detected in the cardia,colon,cecum and rectum.Gas positive cells were the most in the duodenums,while in the esophagus and cardia was not discovered.In the cardia VIP cells were maximum,but in the esophagus,duodenums and ileum did not appear.

结果 消化道中4种免疫阳性细胞形态多样，大多呈椭圆形和锥体形。5-HT阳性细胞数量以结肠最多，空肠和回肠次之，幽门腺区、十二指肠和直肠较少，食管、贲门腺区、胃底腺区和盲肠中未见；SS阳性细胞在幽门腺区数量最多，贲门腺区、结肠、盲肠和直肠中未见；Gas阳性细胞大量出现于十二指肠，在食管、贲门腺区和盲肠未见；除个别器官未见VIP阳性细胞外，在消化道的其余各段均有分布。
