【摘要】 背景:在颈动脉粥样硬化斑块的石蜡包埋工作中,将平均长度约3 cm的颈动脉粥样硬化斑块组织完整地包埋入蜡块中是上述科研工作必须步骤。目的:阐述一种颈动脉粥样硬化斑块整块石蜡包埋处理方法。方法:颈动脉粥样硬化斑块组织取自首都医科大学附属北京天坛医院经颈动脉内膜剥脱术手术取材样本。为了便于连续切片后的组织学层面能够与磁共振成像的信息作精准同层比对,实验在组织石蜡包埋时将颈动脉粥样硬化斑块组织作为一个整体完整地包埋入蜡块中。结果与结论:在实际工作中,借鉴合作方美国华盛顿大学血管成像实验室在斑块处理方面的实践经验,结合实验室的实际情况,通过一种简易包埋方法进行颈动脉粥样硬化斑块的整块石蜡包埋,克服了颈动脉粥样硬化斑块组织整块包埋中的技术难点,为有类似工作需求的同行提供参考和引用。更多还原

【Abstract】 BACKGROUND: Carotid atherosclerotic plaque with the length of about 3 cm completely embedding into paraffin block is a key step.OBJECTIVE: To clarify a method to embed carotid atherosclerotic plaque en bloc in paraffin.METHODS: Carotid atherosclerotic plaque was removed from the carotid endanerectomy at Beijing Tiantan Hospital, Capital Medical University. In order to facilitate the comparison between histological slices from serial sectioning and MRI, we need to embed carotid atherosclerotic plaque en bloc in paraffin.RESULTS AND CONCLUSION: With the guidance of the University of Washington Vascular Imaging Lab, we had established a simple embedding method according to the practice in our lab. With the method, we successfully overcame the technical difficulties in the en bloc embedding of carotid atherosclerotic plaque, which provides a reference for researchers with similar work needs.更多还原
