民间故事对禁忌习俗的攻击及其中心话语

禁忌的本质是虚妄的.在民间故事中,禁忌本身及恪守禁忌的人往往成为被嘲笑和攻击的对象.这种嘲禁型母题显示出对不合时宜的"传统"进行颠覆的强大力量,从一个侧面颂扬了广大民众蔑视迷信的科学生活态度.语言禁忌之所以构成了此母题的中心话语,完全是由于语言禁忌的现实处境所致.     

A Unique Fatal Moose Attack Mimicking Homicide

Fatalities caused by animal attacks are rare, but have the potential to mimic homicide. We present a case in which a moose attacked and killed a woman who was walking her dog in a forest. Autopsy showed widespread blunt trauma with a large laceration on one leg in which blades of grass were embedded. Flail chest was the cause of death. The case was initially conceived as homicide by means of a riding lawn mower. A review of the case by moose experts and analyses of biological trace material that proved to originate from moose, established the true source of injury. The dog probably provoked a moose, which, in response, stomped and gored the victim to death. The injuries resembled those previously reported from attacks by cattle and water buffalo. Fatal moose attacks constitute an extremely rare threat in boreal areas, but can be considered in traumatic deaths of unknown cause.     

基于动脉质子自旋标记技术探讨通督调神针刺对短暂性脑缺血发作患者脑血流的影响

目的 通过磁共振动脉质子自旋标记（arteiral spin labeling proton, ASL）技术探讨通督调神针刺对短暂性脑缺血发作（transient ischemic attacks, TIA）患者脑血流的影响,为针刺预防缺血性脑卒中提供依据。方法 将100例TIA患者随机分为治疗组和对照组各50例,治疗组给予通督调神针刺治疗,对照组给予尼莫地平片口服治疗,共治疗4周。结果 两组治疗后ASL灌注情况及临床疗效比较,差异均无统计学意义（P＞0.05）。结论 通督调神针刺治疗可有效改善TIA患者脑组织低灌注区的脑血流量,疗效与口服尼莫地平片相当。
