Early childhood teachers' preparation and the quality of program outcomes

The issue of the preparation of effective teachers becomes more critical for teachers of early childhood programs. It has been hypothesized that better program quality depends on better-educated teachers. The purpose of this investigation was to explore the importance of a high level of education for all early childhood education teachers. This issue has intrigued early childhood researchers and has prompted a large amount of research studies over the past decades. In order to assess the status of this line of inquiry and to provide guidance for future research, a critical analysis of 40 studies on the preparation of early childhood education teachers and the quality of their educational programs that were published within a 15-year (1989-2004) period is presented here. The analysis consisted of literal and allegorical critical analysis and interpretative critical analyses, which generated results in three main areas that focused on the professional development of the teachers, including teachers' professional development, the importance of a Bachelor's Degree and educational standards for early childhood education teachers.     

喂饲泵应用的临床观察及护理

目的 探讨用喂饲泵行肠内营养摄入的临床应用价值。方法 实验组30例采用喂饲泵控制肠内营养液的滴入速度，对照组采用传统方法，用20ml或50ml注射器灌注营养液，观察两组并发症的发生情况，所得量化指标进行卡方检验。结果实验组其返流、呕吐、腹胀、吸入性肺炎的发生率明显低于对照组。结论应用喂饲泵行肠内营养的摄入，可有效预防并发症的发生。     

家庭暴力及其应对策略

近几十年来，公众和社会逐渐认识到家庭暴力是一种主要的公共健康问题，它影响着不同种族、不同社会、不同经济背景中的个体。目前家庭暴力依然是当今社会中的一大问题。结束家庭暴力要求全体社会的共同关注，包括卫生保障部门、执法部门、社会服务系统联合起来应对家庭暴力。     

中药泡洗治疗糖尿病足90例疗效分析

目的为了观察中药泡洗对糖尿病足的疗效。方法对90例糖尿病足患者用中药（方剂组成：桃仁、红花、桂枝、没药、乳香、花椒、川芎等各10g）水煎制后分为2袋各300ml配合足浴仪泡洗，2次，d，30min／次，10d为1疗程。结果全组90例患者显效66例，有效24例，总有效率100％。结论中药泡洗治疗糖尿病足疗效确切。     

脐带缠绕的临床护理

目的总结脐带缠绕的临床护理体会。方法通过对129例脐带缠绕患者的临床观察，根据病情辩证地提出施扣要点，给予整体护理。结果129例（占同期分娩602例的21．4％）脐带缠绕患者中初产妇104例（80．6％），经产妇25例（19．4％）；经产妇脐带缠绕发生率36．2％（25／69）较初产妇19．5％（104／533）显著增高p〈0．01（u=3．183）；结论对患者临产前、临产中、临产后的各阶段应进行细致临床观察和针对性护理，根据患者的个体特点进行针对性护理是获得满意效果的重要因素。     

一种中西药复方制剂(PESM)对大鼠实验性肾结石形成的抑制作用

用乙二醇法诱导大鼠产生草酸钙结石，用45~Ca示踪测定法了解中草药复方制剂（PESM）对草酸钙结石形成的抑制作用。结果显示，实验组肾脏放射性强度明显减少（实验组3.47±3.52cpm／mg，对照组10.89±14.24cpm／mg）。干肾重量明显下降（实验组306.0±47.0mg，对照组343.1±59.4mg），说明PESM能明显抑制肾脏草酸钙结石的形成。

View ordering for magnetization prepared steady state free precession acquisition: application in contrast-enhanced MR angiography.

Magnetization prepared segmented acquisition requires a view order that maximizes signal contrast during the acquisition of the central portion of k-space. Steady state free precession (SSFP) acquisition further requires a view order that minimizes changes in phase-encoding gradients from one repetition to the next in order to minimize eddy current artifacts. In this article, optimal view ordering schemes satisfying these two requirements are formulated and applied to inversion prepared 3D SSFP contrast-enhanced MR angiography (MRA). Experiments on phantoms and pigs demonstrated improved background suppression and reduced image artifacts.     

新生儿红臀的病原学监测及治疗护理对策

目的探讨新生儿红臀继发感染的主要病原和合适的临床治疗护理方法,评价红臀患儿局部使用抗菌药物的价值.方法对2002年1月～2004年12月收治的132例新生儿的红臀进行病原学监测,并分为观察组和对照组,观察组在传统护理基础上加用含制霉菌素和氯霉素的激素软膏局部使用.比较2组红臀愈合时间.结果132例红臀患儿中,共获取细菌137株,真菌19株;122例(92.4%)存在合并感染的病原学证据;肺炎克雷伯氏菌和大肠杆菌是主要病原,分别占47.4%和19.2%;86例在传统护理基础上经应用含制霉菌素和氯霉素的激素软膏,愈合时间为(4.5±1.8)d,较传护理愈合时间(6.2±3.5)d明显缩短(t=3.083,p＜0.01).结论新生儿红臀常继发各种细菌和真菌感染,局部使用抗菌药物和合理适当的护理可加快红臀的愈合.
