Result: The hemoglobin was lower in the female group than male group(p＜0.001); The endoscopes datum, position and expression of C-erbB-2 protein of both groups showed no statistical difference, but the rate of mucor-bloody stools, change of bowel movement habit, adenocarcinoma, alvine block, mucinous adenocarcinoma, undifferentiated carcinoma, Dukes stage C and D were significant difference(p＜0.05) in young group than old group.

目的：分析青年大肠癌的发病特点和病理特征与中老年大肠癌的不同，为青年大肠癌的预防和治疗提供理论依据。方法：总结我院5年间收治的92例年龄低于35岁青年大肠癌资料进行筛选和研究，对患者性别、内镜资料、临床表现、病理及c-erbB-2蛋白表达和治疗情况进行统计分析，与同期中老年病例作对照。

Though CopRS/CopABCD homologues are found to exist in Pseudomonas fluorescens, the potential role of this system in P. fluorescens has not been investigated. In this study a genetic cluster, consisting of copR, S, C, and D but lacking copAB, was identified in a pathogenic P.

CopRS/CopABCD是细菌用以维持铜内环境稳定的一个系统，虽然已在荧光假单胞菌中发现了CopRS/CopABCD系统的同源物，但其潜在的功能还未知。

结果 不同浓度的食醋溶液作用不同时间对金黄色葡萄球菌、大肠杆菌和白色念珠菌的杀灭效果不同，浓度越大、作用时间越长杀菌效果越好（F=6.89～156.83，P.05）；对手自然菌作用2 min，平均杀灭率为0.991 5±0.003 2；对厨房内台面、砧板、菜刀、碗柜、瓷碗、冰箱保鲜室表面擦拭消毒10 min，对自然菌的平均杀灭率在0.972 0以上；对室内空气自然菌的杀灭率随熏蒸时间的延长而提高（F=121 2.13、502 4.46，P.05），当室内有人时，杀灭率有所降低（t=5.08～30.48，P.05）；置于54 ℃恒温箱（相对湿度≥0.75）存放14 d，醋酸总含量下降

Four goats (42.4±3.5 kg) surgically fitted with cannulas in common bile duct and abomasal were used in 4×4 Latin square design and randomly fed diets contained 20%, 30%, 40% or 50% of starch to determine the effects of rumen escape starch, by altering dietary starch concentration, onα-amylase secretion in goats. Increasing rumen escape starch results in a quadratic increase in pancreaticα-amylase secretion.
