Orem自理模式在脑血管疾病病人护理中的应用

目的探讨自理模式对脑血管疾病病人护理的可行性,提供更好的护理干预措施.方法将121例脑血管疾病病人分为两组,61例采用自理模式护理(观察组);60例采用功能制护理(对照组);观察两组病人的平均平均日、病人对护理服务满意度及并发症.结果观察组病人的平均住院日及并发症的发生率低于对照组,病人对护理服务满意度高于对照组.结论自理模式护理方式对脑血管疾病病人具有可行性,自我护理模式可缩短病人的住院日,减少并发症的发生,促进了病人的康复.     

纳洛酮对大鼠脑外伤后神经细胞凋亡的影响

目的：采用Feeney法自由落体撞击脑损伤动物模型，观察纳洛酮对脑外伤后神经细胞凋亡和脑水肿的影响。方法：90只大鼠分为实验组及对照组，在损伤后15、60min及24h分别予纳洛酮或生理盐水，损伤后第5d断头处死大鼠，TUNEL法测定神经细胞原位凋亡情况，测定损伤侧大脑半球含水理以及光镜下观察细胞形态学改变。结果：与对照组比较，大鼠脑外伤后15及60min静注纳洛酮可保护神经细胞，减少凋亡率，减轻脑水肿；而外伤后24h给药，神经细胞凋亡率以及脑水肿无显著性差异。结论；研究结果提示纳洛酮作为阿片受体的拮抗剂有保护大鼠脑外伤后神经细胞的作用，但应在外伤后尽早用药。     

Fibulin-5/DANCE is essential for elastogenesis in vivo.

The elastic fibre system has a principal role in the structure and function of various types of organs that require elasticity, such as large arteries, lung and skin. Although elastic fibres are known to be composed of microfibril proteins (for example, fibrillins and latent transforming growth factor (TGF)-beta-binding proteins) and polymerized elastin, the mechanism of their assembly and development is not well understood. Here we report that fibulin-5 (also known as DANCE), a recently discovered integrin ligand, is an essential determinant of elastic fibre organization. fibulin-5-/- mice generated by gene targeting exhibit a severely disorganized elastic fibre system throughout the body. fibulin-5-/- mice survive to adulthood, but have a tortuous aorta with loss of compliance, severe emphysema, and loose skin (cutis laxa). These tissues contain fragmented elastin without an increase of elastase activity, indicating defective development of elastic fibres. Fibulin-5 interacts directly with elastic fibres in vitro, and serves as a ligand for cell surface integrins alphavbeta3, alphavbeta5 and alpha9beta1 through its amino-terminal domain. Thus, fibulin-5 may provide anchorage of elastic fibres to cells, thereby acting to stabilize and organize elastic fibres in the skin, lung and vasculature.

Regulation of cellulose synthesis in Acetobacter xylinum by cyclic diguanylic acid

Cellulose is the most abundant renewable carbon resource on earth and is an indispensable raw material for the wood, paper, and textile industries. A model system to study the mechanism of cellulose biogenesis is the bacterium Acetobacter xylinum which produces pure cellulose as an extracellular product. It was from this organism that in vitro preparations which possessed high levels of cellulose synthase activity were first obtained in both membranous and soluble forms. We recently demonstrated that this activity is subject to a complex multi-component regulatory system, in which the synthase is directly affected by an unusual cyclic nucleotide activator enzymatically formed from GTP, and indirectly by a Ca (2+) -sensitive phosphodiesterase which degrades the activator. The cellulose synthase activator (CSA) has now been identified as bis-(3' 5')-cyclic diguanylic acid (5'G3'p5'G3'p) on the basis of mass spectroscopic data, nuclear magnetic resonance analysis and comparison with chemically synthesized material. We also report here on intermediary steps in the synthesis and degradation of this novel circular dinucleotide, which have been integrated into a model for the regulation of cellulose synthesis.
