杨新明  刘昭  成日清 《河北北方学院学报(医学版)》2004,21(5):67-70

目的:结合文献探讨骨旁脂肪瘤的命名、病因、临床病理表现和影像学特点.方法:将国内文献的15例一起列入临床资料分析,本病发生于任何年龄,成人多见,以四肢长管状骨为好发,右侧多于左侧,其次发生于扁平骨(骨盆、肩岬骨、肋骨)、不规则骨(腰椎、骶尾椎)、短管状骨和跗骨;本文22例术前均行X线摄片,7例行CT检查,2例行MRI检查.结果:本病临床误诊率为40.91%,X线误诊率27.27%,CT及MRI诊断率100%;22例均手术切除,病理报告为脂肪瘤,有2例低度恶变;随访2年5例,3年2例(包括恶变1例),4年2例,无一例复发.结论:骨旁脂肪瘤是最佳的命名,病因未明,但与遗传、先天因素、创伤和炎症因素有关;病理表现为带骨蒂的脂肪瘤,细胞学形态为脂肪组织;影像学具有特征性表现;包膜外边缘切除加基底部骨突切除是治疗和防止本病复发的可靠方法.  相似文献   

三种方法治疗异位妊娠效果比较     

焦桂青  李建平 《河北北方学院学报(医学版)》2004,21(1):18-19

目的:探讨三种治疗异位妊娠方法的优缺点.方法:根据71例的异位妊娠病人的病情选择,分成药物保守治疗组、腹腔镜治疗组、剖腹手术治疗组进行分析.结果:药物保守治疗组住院时间长、疗效不确切,但成功者可避免手术.两组手术病人比较,将手术损伤、术后恢复进行统计学分析有明显差异(P＜0.05).结论:腹腔镜治疗异位妊娠是异位妊娠治疗的最佳方案.  相似文献   

中国老年人心脏形态与功能的多普勒超声心动图研究     

王利生  郭凤英  何萍  李向欣  穆铮  张树彬  祁芸芸 《河北北方学院学报(医学版)》1993,(4)

本文以多普勒超声心动图对50例健康中国老年人的心脏形态与功能进行了研究,发现主动脉根部增宽、左房增大、右心室增大为心脏老化之形态特征,而静息状态心脏收缩功能在正常范围,但舒张功能却较差(E/A均值0.97).  相似文献   

舒血宁配合治疗急性脑梗死的临床观察     

薛茜  陈晓春 《河北北方学院学报(医学版)》2004,21(2):11-13

目的:观察舒血宁注射液对急性脑梗死的治疗效果以及对患者血液流变学的影响,综合分析其作用机理.方法:将60例急性脑梗死患者随机分为两组:舒血宁注射液加常规药物治疗组(治疗组)30例,常规药物治疗组(对照组)30例.观察两组患者治疗后有效率、治疗前后神经功能缺损评分以及血液流变学变化.结果:治疗组总有效率86.7%,平均减少积分为(9.33±4.47)分,明显优于对照组的63.4%、(8.50±4.60)分(P＜0.05);在降低全血粘度、全血还原粘度、血浆粘度、红细胞聚集指数、红细胞压积、红细胞刚性指数及升高红细胞变形指数方面与对照组相比,差异有显著性(P＜0.05).结论:舒血宁做为急性脑梗死联合用药,可明显提高临床疗效,其作用机制与扩张血管、降低血液粘度有关,安全可靠.  相似文献

Searching for cochlear implant information on the internet maze: implications for parents and professionals     

Zaidman-Zait A  Jamieson JR 《Journal of deaf studies and deaf education》2004,9(4):413-426

The present study has three purposes: (a) to determine who disseminates information on cochlear implants on the Web; (b) to describe a representative sample of Web sites that disseminate information on cochlear implants, with a focus on the content topics and their relevance to parents of deaf children; and (c) to discuss the practical issues of Web-based information and its implications for professionals working with parents of deaf children. Using the terms "cochlear implants" and "children," the first 10 sites generated by the four most popular search engines (Google, Yahoo, Microsoft's MSN, and America Online) at two points in time were selected for analysis, resulting in a sample of 31 Web sites. The majority of Web sites represented medically oriented academic departments and government organizations, although a wide variety of other sources containing information about cochlear implants were also located. Qualitative analysis revealed that the content tended to fall into eight categories; however, the important issues of educational concerns, habilitation following surgery, and communication methods were either addressed minimally or neglected completely. Using analytical tools that had been developed to evaluate "user friendliness" in other domains, each Web site was assessed for its stability, service/design features and ease of use. In general, wide variability was noted across the Web sites for each of these factors. The strong recommendation is made that professionals understand and enhance their knowledge of both the advantages and limitations of incorporating the new technology into their work with parents.  相似文献

李春永  潘妍婷  薛茜 《河北北方学院学报(医学版)》2004,21(1):43-46

目的:探讨盐酸纳洛酮与β-七叶皂甙钠联合治疗大面积脑梗死的疗效.方法:本文收集我科2001.3～2003.11月住院病人,且符合大面积脑梗死诊断标准30例,2002年12月以前为对照组15例,以后为治疗组15例,治疗组在对照组治疗的基础上加用纳洛酮和β-七叶皂甙钠,两周后采用同一标准进行神经功能缺损评分,并进行统计学处理.结果:治疗组总有效率为80%,无效率6.7%,死亡率13.3%.对照组总有效率30%,无效率30%,死亡率为40%,两组比较有显著性差异(P＜0.05).结论:盐酸纳洛酮和β-七叶皂甙钠联合治疗大面积脑梗死的疗效优于对照组,近期死亡率明显下降.提示这两种药具有脑保护和脱水降颅压作用.  相似文献   

Increasing interest in social studies: Social perspective taking and self-efficacy in stimulating simulations     

Hunter Gehlbach  Scott W. Brown  Andri Ioannou  Mark A. Boyer  Natalie Hudson  Anat Niv-Solomon  Donalyn Maneggia  Laura Janik 《Contemporary educational psychology》2008,33(4):894-914

This study examined the potential of simulations to bolster interest in middle school social studies classrooms. Using a pre–post-design, we examined 305 middle school students (49% female) who participated in the web-based GlobalEd simulation. In contrast to the motivation declines middle school students usually experience, participants in this simulation became more interested in social studies. We investigated four hypotheses as to why these increases may have occurred. We found no support for the possibility that, (a) students’ interest in a particular issue area or (b) their increased valuing of the subject matter, were related to their increased interest. However, results suggested that, (c) the challenging nature of the activity and (d) students’ increased propensity to engage in social perspective taking may have bolstered their interest in social studies. The discussion explores future research directions and whether implications for classroom teachers are warranted given the correlational nature of the research.  相似文献
