    Twenty-four patients with cutaneous ureterostomy at least 6 months after surgery were included in this study. Single-J ureteral catheters were indwelt in 7 patients. Pouch urine was cultured and analyzed from asymptomatic patients and from those with pyelonephritis. Forty-eight bacterial strains were isolated from asymptomatic patients. Thirty-five of these strains consisting of 18 species were isolated from the patients without ureteral catheters. Enterococcus (E.) faecalis (20.0%), Klebsiella pneumoniae (11.4%) and Proteus (P.) mirabilis (11. 4%) were isolated at high frequency. One methicilline-resistant coagulase-negative Staphylococcus (MRCNS) strain was isolated. Thirteen bacterial strains consisting of 8 species were isolated from the patients with ureteral catheters. E. faecalis (23.1%), Eschericia (E.) coli (23.1%) and Pseudomonas (P.) aeruginosa (15.4%) were isolated at high frequency. One E. coli strain harboring extended-spectrum beta lactamase (ESBL) and one MRCNS strain were isolated. Pyelonephritis occurred in 5 patients 14 times during follow-up for at least 6 months after surgery. The patients with ureteral catheters suffered from pyelonephritis (4/7, 57.1%) more frequently as compared to the patients without catheters (1/17, 5.9%) (p= 0.014). P. aeruginosa (26.9%), E. faecium (15.4%), and P. mirabilis (11.5%) were isolated inhigh frequency. One E. coli strain harboring ESBL and one P. mirabilis strain harboring ESBL were isolated. In conclusion, insertion of ureteral catheters in a cutaneous ureterostomy is a strong risk factor for pyelonephritis and development of antibiotic-resistant bacteria. Therefore, urine culture is important in these patients who are under surveillance

    细胞是真核生物的最小生命单元,也是维持生物形态和功能的最小基本单位。细胞在生命过程中时时刻刻都进行着复杂的新陈代谢,细胞内所有信息的传递、物质交换、胞内分子的变化都和细胞的状态有着密切联系。它是生物个体在生命过程中疾病产生和发展的基础。自从人类发明了显微镜,对生命的研究对象开始由宏观的个体、器官、组织向细胞、亚细胞水平发展。现在,人们对细胞的整体组成以及细胞内亚结构已经基本确定。尽管许许多多的科学家对细胞的研究已经深入细胞内(细胞核、DNA、核内蛋白质、脂质),但是由于细胞这一体系的特殊性及复杂性,因而对细胞的许多研究问题都未能得到解决。所以当前亟须发展多种细胞检测和分析技术,以研究细胞中各类...Cell is the smallest unit of life, and also the smallest basic unit of maintaining biological morphology and functions of eukaryotic organisms. Cells experience complex metabolism in every moment of the life processes. All cellular information transmission, material exchange, and molecular changes are closely related with the state of cells.

    近年来,中国电信企业呈现了前所未有的快速增长势头。但随着中国经济市场化的程度越来越高,几家电信企业间的竞争也越来越激烈,电信资费的不断下降、用户发展成本的不断提高,使得中国电信企业的盈利空间越来越小。在这种情况下,如何制订科学的价格策略,避免盲目竞争,以及如何寻找可压缩的成本空间,成为电信企业的当务之急。但目前中国电信企业面临的现状是:所提供的服务已远非传统的话音业务,增值业务和数据业务的比重不断提高,电信服务的多元化和多样化已成必然趋势,相伴随而产生的各种资费套餐层出不穷,用户品牌及用户群体划分也越来越细致,传统的粗放的成本管理方法已不能满足科学的价格策略形成机制的需求。本文从作业成本法的概...In recent years, communications industry in China has witnessed an unprecedented increase. However, with the further development of China’s market and economy, competitions among communications companies become more fierce. With the decrease of communications fee and the increase of cost of the development of customers, the profit margin becomes smaller and smaller. Under such circumstances, to fi...学位:工商管理硕士院系专业:管理学院高级经理教育中心(EMBA项目)_高级管理人员工商管理硕士(EMBA)学号:X200715607
