Abstract］ objective to discuss the influencing factors of healing up of anastomosis between traditional and morden ideas and question the more reasonable method of intestinal tract preparation in stage one operation.methods twenty-six patients with colon cancer were divided into 3 groups:colostomy group（8 cases）,washing group (9 cases) and suction group (9 cases).all the patients underwent colectomy plus stage one anastomosis and exteriorization with different interoperative preparation with which we compared the healing up of anastomosis within the three groups.results there were 3 cases having fistula in the colostomy group （8 cases）;one case in the washing group,but all the patients in the suction groups gained stage one healing up.conclusion as a method of emergency interoperative peparation,stool suction has a better healing up of anastomosis than colostomy and washing;it is advantageous to observe the healing up of anastomosis through colectomy plus stage one anastomosis and colon-outlying.

目的 探讨影响吻合口愈合因素的传统与现代观念并进一步探讨一期手术中更为合理的肠道准备方式。方法 26例降结肠癌分为造瘘组（8例）、冲洗组（9例）和粪便吸引组（9例）三组，术中分别采用3种不同方式行紧急肠道准备，所有病人均采用结肠切除一期吻合加外置的方法，对比观察三组病人的吻合口愈合情况。结果造瘘组（8例）有3例发生瘘，冲洗组有1例发生瘘，粪便吸引组全部一期愈合。结论粪便吸引作为一种术中紧急肠道准备方法，其吻合口愈合情况优于前两组；结肠一期吻合加外置的方法有利于观察吻合口的情况。

The comparison of the predominant bacterial community structure in the gastrointestinal walls between Lutjanus sebae (Cuvier, 1816) and Ephippus orbis (Bloch, 1787) based on 16S rDNA PCR-DGGE fingerprint using a culture-independent method was conducted in the paper. The results showed that abundant bacterium were planted in the gastrointestinal walls of both marine finfish species, the similarity was above 50% in the community structures in the gastrointestinal walls with the highest similarity of 67% in the bacterial composition between the intestinal wall of Luljonus sebae and that of Ephippus orbis, and the walls of the stomach and the intestinal in one fish shared the same most predominant bacteria species, which might reflect the same aquaculture environment and the diet fed for both finfish species.

本文采用免培养的16S rDNA梯度凝胶电泳技术对集约化海水网箱养殖川纹笛鲷Lutjanus sebae、及圆白鲳Ephippus orbis消化道壁优势菌群结构进行了比较分析研究结果显示川纹笛鲷及圆白鲳消化道壁存在着大量细菌群落，对DGGE指纹图谱聚类分析表明两种鱼肠道壁及胃壁菌群组成相似度高于50%，其中二者肠道壁细菌组成相似性最高(67%)，这些可能与两种鱼养殖在同一水域、摄食相同饵料相关，另外通过软件对DGGE指纹带谱相对丰度分析表明同种鱼肠道壁及胃壁具有相同最大优势菌群。

The first is improving intestinal physical defensive barrier: restoring intestinal perviousness and altering intestinal micro-circumstance and activating generation of benefical bacteria; The second is improving intestinal immunity defensive barrier and eliminating inflammatory reaction.

益生菌治疗UC的机理，主要表现在两个方面：一方面是提高肠道非免疫防御屏障功能，包括恢复肠道黏膜通透性和改变肠道微生态环境，并激活内源性细菌的代谢；另一方面是提高肠道免疫防御屏障，通过改善肠道免疫防御屏障而消除肠道炎症反应。

The injury to intestinal mucosal immunity ,in addition to increased intestinal permeability, allows bulk of intestinal toxic substance to enter blood and displacement of intestinal bacterium causing,pyemia ,followed by multi-organ dysfunction syndrome.

另一方面辐射造成肠道粘膜免疫细胞的损伤，使其功能抑制，加之肠道机械屏障损伤所致的肠道通透性增加，肠道内大量毒性物质入血，细菌移位，造成严重的肠源性感染，继发多器官功能不全，后者是急性放射病抢救失败的重要原因之一。

To obtain a better understanding of the microbiota inhabiting the intestinal tract of wood-feeding lower termites, the European subterranean termite, Reticulitermes santonensis (Isoptera: Rhinotermitidae), was used as a model system. The diversity and structure of the bacterial community in the different niches of the gut, as well as the distribution and location of major bacterial phylotypes within the intestinal tract was evaluated using various molecular techniques such as clonal analysis, DNA fingerprinting, and fluorescence in situ hybridization. In addition, the symbiotic bacteria associated with the flagellate, Pyrsonympha vertens in the gut of the closely related Eastern subterranean termite, Reticulitermes flavipes , were phylogenetically characterized.
