Objective To explore the value of combined biliary and duodenal sidling in the palliative treatment of pancreatic head carcinoma.

目的 探讨胆道内支架和十二指肠金属内支架联合应用治疗胰头癌的价值。

Ingested feed is repeatedly ground and mixed in the gizzard, sent back to the proventriculus for more peptic juice application and returned to the gizzard.

第二种肠回流使食糜从十二指肠和空肠向胃区回流，这种回流在家禽体内大约每小时发生三次，但其发生频率随日粮脂肪增加而增加，随日粮纤维增加而减慢，肌胃内表面的典型银黄着色就是由于肠内食糜回流到肌胃而暴露于胆汁的证据。

No matter whether the patients of pancreatic diseases have enteroparalysis or not,the enteral nutrition should be administrated at onset or within 24-48 hours postoperatively.

也有学者认为：避开胃和十二指肠的肠内营养无显著加重胰腺损害的危险，胰腺疾病患者无论是否存在肠麻痹，发病或手术24-48小时即可给予肠内营养支持。

The duodenal juice mainly consists of the bile acid, which is a sort of lipophilic steroid and may result in direct injuries of mucosal epithelial cells and their tight junctions. Some researches have showed that the bile acid directly damaged the chemical environment of mucosa surface and played a synergistical role in gastric mucosal lesions along with gastric acid and H.

十二指肠反流液中主要成分为胆汁酸，胆汁酸是十二指肠反流液中造成黏膜损伤的主要成分，为一种亲脂性类固醇，直接破坏黏膜上皮细胞以及细胞间的紧密连接，同时还对腔内及黏膜表面的化学环境造成直接的影响，增强胃酸、H。

Intramural hematoma of the duodenum is a condition in which, spontaneously or result of trauma, a localized collection of blood extravasates into the subserosal and interstitial tissue of the duodenum.

十二指肠壁内血肿，不论是自发性或外伤性起的，是一种局部血液渗入於十二指肠浆膜层下和间质维织中的现象。

In rat esophagus, the positive varicosities and fibres could be observed in the circular muscle layer and the muscularis mucosae layer at 21st day before birth. With the development of rat digestive tract, neurokinin A-immunoreactivity positive nerves could be observed gradually in the epithelium, submucosa, longitudinal muscle layer, myenteric plexus and submucosal plexes, while mature nerve fibres could be seen at one month after birth. 2. In rat stomach, the positive reaction of NKA initially happened in the myenteric plexus at the 14th day of embryo, and then appeared on circular muscles, longitudinal muscles, submucosal, muscularis mucosae, lamina propria and epithelium. 30 days after birth, expression of NKA is same as seen in adaulthood. 3. In rat small intestinal, the NKA-IR could first be found in the myenteric plexus of the duodenum, jejunum and ileum at 14th , 15th and 17th day before birth respectively. Then the NKA-IR occurred in the longitudinal muscle layer, circular muscle layer, intestinal villus, intestinal gland, muscularis mucosae, submucosa, submucosal plexes, mucosa plexus and deep muscular plexus.

结果 1、在食管，于胚胎21天的粘膜肌层和环肌层内观察到神经激肽A免疫阳性膨体纤维，出生后，随幼鼠的生长发育，相继在上皮，粘膜下层，纵肌层、肌间丛、粘膜下丛有NKA-IR表达，30天时已和成年鼠相似；2、在胃，首先于胚胎14天的肌间丛出现NKA-IR的表达，随发育相继在环肌、纵肌，粘膜下层、粘膜肌、固有膜及上皮内出现NKA-IR的表达，30天时具备成年鼠的分布特征；3、在小肠，分别于胚胎14、15、17天的十二指肠、空肠和回肠的肌间丛处出现NKA-IR的表达，随发育相继出现在纵肌、环肌、绒毛、小肠腺周、粘膜肌、粘膜下层、粘膜下丛、粘膜丛、深肌丛。

Experiment(2): Six one years old gansu high mountain fine wethers(avg wt 25~30 kg) fitted with permanent ruminal and proximal duodenal cannulae were assigned to double 3×3 Latin square design, to measure the apparent digestibilities of nutrients in rumen, postrumen and total tract and the apparent nitrogen retention as well as the dynamic changes of the rumen metabolic parameters in wethers fed with diets which SC:NSC ratio were respectively 1.57, 1.95 and 2.29.

试验：选用6 只1 岁左右，体重25~30kg，装有永久瘤胃瘘管和十二指肠近端套管的甘肃高山细毛羯羊，采用3×3 有重复拉丁方设计，研究了SC： NSC 比例(1.57、1.95、2.29)饲粮的瘤胃内、瘤胃后和全消化道营养物质表观消化率及氮表观存留率，以及瘤胃内环境参数的动态变化。

MUC3 apomucin and its mRNA were mainly situated in the cytoplasms of goblet cells and columnar-type cells of duodenum and column.But no reactive signal of MUC2 and MUC3 genes' product was found in the mucous droplets.

MUC3核粘蛋白及其mRNA主要存在十二指肠和结肠的杯状细胞和柱状细胞胞浆内，而杯状细胞的粘液滴内无MUC2、MUC3基因产物的阳性反应信号。
