思政工作对医院文化建设的影响探析

随着社会的进步与发展，我国的医疗事业单位也在逐渐完善。思政工作在医院文化建设中占有重要的地位，是医院管理的重要内容，是医院可持续发展的思想保证和动力支持。本文主要从思政工作在医院文化建设中的作用意义，以及如何实现其作用的发挥两个方面进行简要的分析。     

ULTRASTRUCTURAL INVESTIGATION OF HEALING OF EXPERIMENTAL FRACTURE TREATED ACCOR.DING TO THE PRINCIPLE OF ACTIVATING CIRCULATION AND ALLEVIATING STAGNATION

Radix Salviae Miltiorrhizae, a drug activating the circulation and alleviating stagnation, was ad ministered t0 50 New Zealand rabbits that had re- ceived standardized fractures of the radius. Radio graphs of the fractures showed that callus formation appcared earlier and was denser than in 50 control rabbits studied earlier. Transmission electron micros copy revealed five favorable effects of the drug, the first three of which were cellular. First, the osteo genic cells (the progenitors of the csteob:asts and chondrocytes) increased in both number and sites of distribution. Second, the fibroblasts, in addition to changing in configuration, showed very active pro- tein synthesis, with exuberant extracellular coflagcn fibril formation. The normal process of fibroblast degeneration was also expedited. Thus, the replace ment of fibroblasts by bony tissue was promoted. Third, an increased number of osteoclasts emerged in different areas of fracture callus and thus remodel ing was facilitated. Fourth, there was exuberant collagen fibril formation, which promoted p*:oduc tion of organic matrix. Fifth, the swollen mito- chondria of the fibroblasts contained more dense cal cium granules and thus provided more calcium for the calcification of matrix vesicles and collagen fibrils.     

脐血管栓塞伴羊水减少1例及文献回顾

脐带是母胎间气体交换、营养物质供应和代谢产物排出的重要通道.脐带是胎儿循环中最薄弱部分,当脐带受压或出现病变时,可直接或间接引起胎儿血液循环障碍,导致胎儿缺氧、生长受限,甚至死亡[1].脐血管栓塞临床上极少见,但危害极大.因脐血管栓塞研究资料有限,目前国内外涉及的文献以个案报道居多,尚无大样本量的研究,故对于脐血管栓塞...
