多媒体教学在医学图像分析课中的作用

医学图像分析是研究生的一门重要基础课，它在 医学基础理论研究和临床实验研究中发挥着重要的作用。它广泛地应用于解剖学、组织胚胎学、肿瘤病理学、放射医学、免疫学、细胞生物学、分子生物学等学科的研究中。如射Ｘ光图像、显微镜图像及放射性同位素图像进行图像处理或进行几何参数和平均光密度的定量等。在医学图像分析课中将课程难点、重点和一些难以用语言表达清楚的内容利用多媒体进行教学，学生最易接受，最为喜爱。     

THE SIGNIFICANCE OF FORM FACTOR IN THE QUANTITATIVE ANALYSIS OF THE MORPHOLOGICAL FEATURES OF BREAST CANCER NUCLEI

Objective In the present study, an important aspect in medical image analysis, quantification of form factor was investigated. It is suggested that nuclear form of both normal and cancer cells of the same tissue should be taken into account when FF( form factor) is analyzed.The value of FF can't be independently used to serve as evidence. Because breast tissue is complex, breast cancer cells take on diverse and complicated morphological features.Methods Slides of the tissue sections of breast cancer were pathologically confirmed and analyzed in terms of the morphological parameters using DMRXA full-automatic bio-fluorescent microscope and Q550IW computer(Leica, Germany). Of the samples examined, there were 9 cases of adenocarcinoma and 6 normal controls.Results Statistical analysis was performed using SAS software. The results are listed in Table Ⅰ. We found that the nuclear area, perimeter, length and breadth of breast cancer cells were significantly higher than those of normal breast cells(P<0.01). From the data given in the paper it can be seen that FF in the control is significantly higher than that in breast cancer.Conclusion Breast tissue is complicated, consisting of simple cubiodal epithelium, simple columnar epithelium and multiple columnar epithelium, etc. These different cells may have round or ovoid nuclei. Breast cancer cells take on diverse and complicated morphological features. They are classified as duct, lobular and special carcinoma according to their histogenesis and morphological structures. Their nuclear morphological features are diverse as well. Therefore, nuclear form of both normal and cancer cells of the same tissue should be taken into account when form factor is analyzed, nuclear FF alone is not reliable enough to distinguish normal from malignant breast cells.     

医学视听教材目录微机管理系统

近年来随着视听教育事业的发展,许多高等院校相继建立了电教室或电教中心,各种视听资料也与日俱增。如何有效地管理并能迅速准确地查找所需的各类资料,已成为一个急需解决的问题。为此,我们在微型计算机上开发了一个视听资料目录管理系统,     

外伤性进展性颅内血肿的观察与对策

回顾性分析52例外伤性进展性颅内血肿的临床资料,认为早期应用甘露醇、伴有脑挫伤的小血肿、不规则脑内血肿、高血糖等均可引起血肿增大。通过意识状态观察、动态复查CT、颅内压监护能早期明确诊断。     

重型脑外伤颅内血肿患者手术前后护理实践

重型脑外伤颅内血肿是一种常见的、致命的、可逆的继发性病变.颅内血肿病人病情重、变化快,特别要了解有无原发性意识丧失、意识丧失后是否经过典型的中间清醒期,又再度出现意识障碍,并渐进加深,如有中间清醒期,应高度怀疑颅内血肿.     

定量分析的显微医学图像的获取条件

目的 本文阐述了医学图像的来源和定量分析。并着重对进行光密度定量的显微医学图像的获取条件加以讨论。方法 用显微镜通过CCD获取显微医学图像,采用光密度参数进行分析。结果 光密度定量需借助分割图从原始图上测量,但获取原始图时由于光路、视场光分布等问题使对光密度参数定量时产生误差。结论 为使唤显微医学图像定量的结果更加可靠、准确,在图像获取时应注意下列问题。保持光路的稳定,消除显微镜视场光强度分布的不均匀-阴影校正等。     

医学图像分析实验教学改革的研究与实践

医学图像分析实验是医学图像分析教学的重要环节。我们通过不断地研究和实践 ,走出传统实验教学模式 ,摸索出一套适合当前医学图像分析的实验教学模式 ,从而将理论性实验与综合能力的考核相结合 ,不仅使学生掌握医学图像分析实验的基本操作技术 ,而且能培养学生的综合能力和综合素质     

人工髋关节置换术老年患者的护理

目的探讨人工髋关节置换术老年患者的护理与康复指导,以提高护理水平。方法回顾分析58例人工髋关节置换术老年患者的护理过程。结果58例患者均施行整体护理,无一例患者出现深静脉血栓、脱位、关节僵硬、肺部感染等并发症。结论人工髋关节置换术配合整体康复护理,能明显缩短病程,促进康复。     

不同的清洗灭菌方法对无菌物品质量影响的研究

目的研究不同的清洗灭菌方法对无菌物品质量的影响。方法将需清洗、灭菌的物品分成对照组和研究组,分别使用手工清洗、机械清洗以及不同的灭菌方法,监测灭菌后的物品微生物监测合格率、灭菌干包合格率、包装合格率、洗涤合格率,并比较其差异。结果2组灭菌物品的微生物监测合格率、灭菌干包合格率、包装合格率、洗涤合格率等方面差异有统计学意义（P〈0．01）。结论通过机械的清洗、脉动真空高压灭菌方法能严格保证无菌物品的质量。
