Background Continent cutaneous diversion （CCD） has been widely used in almost any lower urinary reconstruction. We have been continually trying to modify this procedure because of the high complications rate, especially as they relate to the efferent tube. In this study, we reported a modified procedure with a tapered ileum wrapped by the rectus abdominalis flap （RAMF） and assessed the feasibility of this new technique to achieve urinary continence. Methods A procedure in which two ileal segments were tapered and connected to a U-shaped reservoir was performed in ten dogs. A RAMF with its blood supply was wrapped around one of the tapered ileum. In control groups, the tapered ileum was brought to the abdominal skin. Urodynamic studies were conducted In the 1st, 3rd and 6th months post-operatively. The data of maximum inner pressure （MIP） and functional pressure length （FPL） in every group at each phase were recorded. Retrograde radiograms of the efferent limbs were performed before sacrifice. Results MIP in the study group was significantly higher than that in the control group at each phase （P 〈0.05）. However no significant differences in MIP or FPL were found in the study group between an empty and full reservoir. In the control group, MIP increased （P 〈0.05） and FPL decreased significantly （P 〈0.05） compared with an empty and full reservoir. Retrograde radiograms confirmed that efferent limbs were positioned straigh beneath the abdominal wall. Histological examination of the study group demonstrated a layer of striated muscle around the outside surface of the ileum. Conclusion The continent mechanism of tapered ileum can be enhanced by extra support from wrapped RAMF.

本文认为,我国自1995年开始政府采购制度试点工作以来,政府采购制度工作已取得了明显成效,不仅强化了财政支出管理,提高了资金使用效率,而且积累了一定的经验。但目前我国政府采购制度还很不成熟,各级地方政府采购工作仍存在明显不足。加入W TO必将对我国政府采购资金、政府采购供应商、政府采购机构等产生一系列影响。文章认为,面对加入W TO带来的机遇与挑战,必须借鉴W TO其他成员国政府采购的先进经验,结合国情完善我国政府采购制度,必须严格遵守《政府采购法》,形成规范的管理制度和操作程序,强化监督机制;积极推广电子网络技术在政府采购中的应用;利用政府采购适度保护民族企业;强化政府采购人员的培训。

汽车焊装是汽车生产中的重要环节,目前生产人员主要依靠经验进行焊点路径规划,导致工作量大、效率低。针对这一问题,提出了用ACO_PSO混合算法计算得出合理的焊接路径,并与实际工人规划的传统路径进行比较,再与ACO算法和PSO算法的实验结果比较,从而证明该算法更优。然后在ROBCAD中建立三维仿真模型,解决了可达性、干涉等实际生产过程中的常见问题,最后计算出焊接过程所需的时间。研究结果表明,ACO_PSO混合算法对改善机器人节拍和提高生产效率有一定的帮助,进一步提出了焊接路径规划的研究重点和发展方向。

过渡金属大环配合物(例如酞菁和卟啉)对氧的电化学还原具有很高的催化活性,因而是目前电化学最活跃的研究领域之一.关于氧在过渡金属大环配合物上电化学还原机理,一般认为与过渡金属的价态变化有关.近年来,由于稀土双酞菁具有电致变色(electrochromic)的特性,引起了人们极大的兴趣,并对它们的电化学行为进行了一系列的研究,但关于它们对氧的电化学还原作用却未见报道.我们利用循环伏安法研究了某些稀土单酞菁和双酞菁对氧的电化学还原的影响,并提出了氧的电化学还原的反应历程.
