护理本科生创造性思维培训

[目的]对护理本科生实施创造性思维训练,并评估该训练方案的有效性。[方法]对20名护理本科生实施为期3个月的创造性思维培训,并与24名不接受培训者进行对照。采用《创造性思维练习》量表对培训前后学生的创造性思维进行测定。[结果]培训后实验组较对照组的创造性思维总分及流畅性得分有显著提高(P<0.05);变通性和独创性得分无统计学意义(P>0.05)。[结论]创造性思维培训对提高护理本科生创造性思维总体有效,其中对提高创造性思维的流畅性效果显著。     

妇科恶性肿瘤放射治疗反应及并发症处理

张继泽主任医师逆转萎缩性胃炎经验举隅

慢性萎缩性胃炎是以胃黏膜上皮和腺体萎缩、黏膜变薄为特征的慢性疾病。属中医胃脘痛、胃痞等范畴。其病因病机较为复杂,多与饮食不调、情志不畅有关,尤其是饮酒、过食刺激之品,致使脾胃受损,阳气郁遏不振,纳运失司,化源不足,气血阴液亏乏;或中焦运化无力,湿邪滞塞,郁而化热;或     

Reproducibility of ultrasound pachymetry using the Sonogage Corneo-Gage Plus 2.

PURPOSE: The aim of this study was to determine the reproducibility of measurements made using the Sonogage Corneo-Gage Plus 2 (Cleveland, Ohio) ultrasound pachymeter of total corneal and corneal epithelial thickness in 5 different regions of the cornea. METHODS: Twenty-seven subjects at the New England College of Optometry (NECO) and 20 subjects at the Southern College of Optometry (SCO) were enrolled in this study. Measurements were taken of the central cornea as well as the nasal and temporal regions of the midperipheral and peripheral regions of the right cornea of each subject. Identical measurements were again taken in these subjects 1 week later at approximately the same time of day. Within-subject variations were then assessed using paired t tests. RESULTS: The only significant measurement differences that were found between visits were for full corneal thickness at both the nasal and temporal midperipheral locations. The mean differences for these locations were 13.5 microm and 13.7 microm, respectively. CONCLUSIONS: Epithelial corneal thickness and central and peripheral total corneal thickness measurements using the Corneo-Gage Plus 2 pachymeter were reproducible; however, midperipheral total corneal thickness measurements showed poor reproducibility.     

儿科背式输液架的研制与应用

输液架是医院不可缺少的工具之一，国内医疗单位使用的输液架多种多样，但仅适用于病房使用，而适合儿科患儿移动的背式输液架甚少。针对以上缺陷，我们自行设计了一种可调式背式移动输液架，已应用于500例儿科患儿，效果较好。现介绍如下。     

表皮生长因子对牛眼小梁细胞c—fos基因表达的诱导

目的研究表皮生长因子（ｅｐｉｄｅｒｍａｌｇｒｏｗｔｈｆａｃｔｏｒ，ＥＧＦ）对小梁细胞的作用。方法应用分子杂交技术研究ＥＧＦ对体外培养的牛眼小梁细胞ｃ－ｆｏｓ基因表达的诱导和３Ｈ胸腺核苷酸（３Ｈ－ｔｈｙｍｉｄｉｎｅｉｎｃｏｒｐａｒａｔｉｏｎ，３Ｈ－ＴｄＲ）掺入法观察细胞ＤＮＡ的合成。结果小梁细胞的３Ｈ－ＴｄＲ掺入率随着ＥＧＦ浓度不同而变化，浓度为２０～１５０ｎｇ／ｍｌ时，细胞掺入率随浓度增加升高（Ｐ＜０．０１）。与对照组相比，ＥＧＦ刺激停止生长的小梁细胞０．５小时后，ｃ－ｆｏｓ基因开始表达，１小时后达高峰，至２小时后消失。不同浓度ＥＧＦ刺激小梁细胞１小时后，ｃ－ｆｏｓ基因表达呈浓度依赖性。结论实验结果表明ＥＧＦ刺激小梁细胞增殖或进入生长状态，可能与ｃ－ｆｏｓ基因产物的信号传递作用有关。

外阴汗腺癌七例临床分析

目的：总结外阴汗腺癌的临床特点及治疗方法。方法：对７例外阴汗腺癌病例进行回顾性分析。结果：外阴汗腺癌的发病年龄为４０～５８岁。７例患者的治疗为局部扩大切除或根治性外阴广泛切除，２例辅以术后放疗。７例中５例存活５年以上，其中１例曾在首次治疗后第７年、１１年２次复发并于第１７年死于肿瘤。２例存活＜５年，１例在术后２年半死于脑出血，１例因脊椎广泛转移在术后１年零９个月死亡。结论：外阴汗腺癌的预后较好，局部扩大切除或根治性外阴切除，是首选治疗方法。
