摘要： Purpose This study used noninvasive, fluorescence lifetime imaging microscopy (FLIM)-based imaging of NADH and FAD to characterize the metabolic response of mouse embryos to short-term oxygen deprivation. We investigated the response to hypoxia at various preimplantation stages. Methods Mouse oocytes and embryos were exposed to transient hypoxia by dropping the oxygen concentration in media from 5-0% over the course of similar to 1.5 h, then 5% O-2 was restored. During this time, FLIM-based metabolic imaging measurements of oocyte/embryo cohorts were taken every 3 minutes. Experiments were performed in triplicate for oocytes and embryos at the 1- to 8-cell, morula, and blastocyst stages. Maximum hypoxia response for each of eight measured quantitative FLIM parameters was taken from the time points immediately before oxygen restoration. Results Metabolic profiles showed significant changes in response to hypoxia for all stages of embryo development. The response of the eight measured FLIM parameters to hypoxia was highly stage-dependent. Of the eight FLIM parameters measured, NADH and FAD intensity showed the most dramatic metabolic responses in early developmental stages. At later stages, however, other parameters, such as NADH fraction engaged and FAD lifetimes, showed greater changes. Metabolic parameter values generally returned to baseline with the restoration of 5% oxygen. Conclusions Quantitative FLIM-based metabolic imaging was highly sensitive to metabolic changes induced by hypoxia. Metabolic response profiles to oxygen deprivation were distinct at different stages, reflecting differences in metabolic plasticity as preimplantation embryos develop.

摘要： 线索模型理论认为个体利用不同的线索进行学习。组织学与胚胎学知识点繁多,对于医学初学者来说记忆困难。在教学过程中建立一条清晰的主线,通过组织学与胚胎学学科内在逻辑、问题、器官(系统)功能、时空及屏障等为线索,把零散的知识点进行串联,形成系统的知识链,构建出一种全新的对话型教学模式,有助于提高组织学与胚胎学教学效果。

关键词： PBL教学法   解剖及组织胚胎学   教学   应用效果  

摘要： 目的:分析PBL教学法在解剖及组织胚胎学教学中的应用效果。方法:选取2018年9月-2019年7月解剖及组织胚胎学实习学生60名,按照学生意愿分为两组,各30名;对照组应用传统教学模式;观察组应用PBL教学法。比较两组教学质量及学生对教学的满意率。结果:观察组学生学期末成绩分数及对教学的满意率均高于对照组,差异有统计学意义(P<0.05)。结论:解剖及组织胚胎学教学中使用PBL教学法,使学生对知识的掌握水平得到显著提升,并且学生对教学的满意率较高。
