多媒体技术在泌尿外科教学中的应用探索

多媒体教学应用于泌尿外科中,将抽象的教学信息直观、形象、生动地展示给学生,可增强学生的学习主动性,解决了传统教学的难点,提高了教学质量。但在教学实践中,不可完全忽视传统教学,提高多媒体课件的制作质量。只有将多媒体教学与传统教学相结合才能不断提高教学质量。     

Histological and morphometric evaluation of the urethra and penis in male New Zealand White rabbits

This stereudy aimed at performing a histological and morphometric evaluation of the urethra and penis of male rabbits. Seven male New Zealand White rabbits weighing 2.1–3 kg were used in the study. The whole urethra, from the urinary bladder to the external urethral orifice, was dissected from the rabbits, and the tissue was sliced into sections at an interval of 2 mm. The sections were stained with haematoxylin–eosin, Masson–Goldner trichrome stain, Van Gieson's stain and Movat–Russell modified pentachrome stain. A detailed evaluation of the morphology and morphometry was performed. The parameters assessed were the type and height of epithelium, thickness and composition of connective tissue, and thickness and structure of muscularis. The histological structure of the rabbit urethra was found to be similar to humans. However, although the rabbits were found to have the same type of penis as the humans, the internal structure of the corpora cavernosa, the relative thickness of the tunica albuginea and the rudimentary glands of the penis were found to differ in these animals. The results of the present study may be useful in the designing of implants, drug testing or surgical procedures on the physiological and pathological urethra.     

微课教学法在泌尿外科实习生培养中的应用研究

目的 探讨微课在泌尿外科临床实习生培养中的应用及效果。方法 根据泌尿外科实习生培养教学大纲,采用摄像、PPT、网络教学视频资源等制作微课视频。将2015年9月-2016年8月泌尿外科全体实习生设为对照组,将2016年9月-2017年8月泌尿外科全体实习生设为实验组,实验组采用传统教学结合微课教学的方式,对照组采用传统教学方式,通过理论考试、临床操作考核、病例分析能力及匿名调查问卷来评价教学效果。结果 实验组理论考试成绩、临床操作及病例分析能力成绩均优于对照组（P<0.05）,实验组对教学效果各项目的评分明显优于对照组（P<0.05）。结论 微课在泌尿外科临床实习生培养中可以起到很好的辅助教学效果,能增强教学效果,值得推广应用。
