目的为了解医学专业与师范专业大学生对艾滋病病毒(HIV)感染者/艾滋病(AIDS)病人(简称HIV/AIDS病人)歧视水平的差异。方法于2016年3月采用中文版zelaya艾滋病歧视量表,对381名医学专业大学生和457名师范专业大学生施测。结果医学专业大学生担心感染维度(t=-7.843,P<0.001)和耻辱偏见维度(t=-3.180,P=0.002)得分低于师范专业大学生,在社会歧视维度得分高于师范专业大学生(t=3.628,P<0.001),差异有统计学意义。除耻辱偏见维度外(t=2.756,P=0.007),有无传染病亲友大学生在各维度得分差异无统计学意义。结论医学专业与师范专业大学生均在一定程度上对HIV/AIDS病人存在歧视,高校应有针对性地开展相关知识教育。

医学生职业素养的培养是人文医学教育的重要任务,但目前对医学生职业素养的构成和各阶段教学目标存在争议。通过文献分析和教育教学实践,将职业技能和人文精神归纳为医学生职业素养的组成部分,其中人文精神由利他主义、沟通能力和团队合作组成。同时,在医学教育过程中将各部分划分为理论目标、发展目标和实践目标三个教学阶段,在每个阶段有针对性地提出培养目标和教育途径,以期为医学院校开展医学生职业素养教育和相应的教学改革提供参考。

我国是肝病大国,各种肝病严重影响人民健康,手术是多种肝病的重要治疗手段之一.术前肝功能评估对于手术方案制定发挥极为重要价值,其中尤以三维定量肝功能成像技术备受临床关注.近年来分子影像突飞猛进,恰巧这也是核医学分子影像技术的优势所在.大量研究证实新型肝细胞去唾液酸糖蛋白受体显像剂^(99m)Tc-半乳糖基人血清白蛋白(^(99m)Tc-galactosyl-human serum albumin,^(99m)Tc-GSA)能够于无创条件下较为准确地反映肝功能状态,但现有研究尚处于初始阶段,仍待深入的临床研究.本文旨在系统阐述^(99m)Tc-GSA单光子发射计算机断层成像肝受体显像基础上,结合已有临床研究及新进展,探索其潜在临床应用前景及未来发展动向.
