目的：探讨眼科临床指南结合团队式学习(team-based learning,TBL)教学课程在眼科住院医师规范化培训中的应用及教学效果。方法：本研究选取2022年1月—2023年6月在广州医科大学附属第一医院眼科进行住院医师规范化培训的15名住院医师作为研究对象，先后交替使用自学讲课、TBL教学这两种教学模式进行眼科临床指南学习，通过填写满意度调查问卷及评估出科考通过率、学业水平测试成绩、结业考通过率，从主观及客观角度探讨临床指南结合TBL学习模式的教学效果。结果：住院医师对增加眼科临床指南学习具有较高评价，且不认为会增加其学习负担。开展指南学习后，住院医师出科考试及格率、学业水平测试通过率、结业考通过率均为100%。在培养团队合作能力、改善学习氛围两方面，TBL讲课的满意度均高于自学讲课(均P＜0.001)。93.3%(14/15)的住院医师更喜欢TBL教学模式。结论：眼科临床指南结合TBL教学是一种有效的教学模式，住院医师在主观满意度调查问卷及客观考试成绩的评估中，均达到满意的教学效果。
Objective: To investigate the application and teaching effect of clinical guidelines combined with team based learning(TBL) teaching courses in standardized training for ophthalmic residents. Methods: 15 residents who received standardized training in the ophthalmology department of the First Affiliated Hospital of Guangzhou Medical University were recruited from January 2022 to June 2023. Self-study teaching and TBL teaching were successively applied to teach the clinical guidelines of ophthalmology. The subjective and objective teaching effects were evaluated by satisfaction questionnaire, passing rate of phase examination, achievement of academic proficiency test and passing rate of final examination. Results: The clinical guidelines enjoy the high opinion in the residents, and would not be strengthen their learning burden. After the residents studied clinical guidelines, their passing rate of the phase exam, academic proficiency test and final examination were all 100%. In terms of cultivating teamwork ability and study atmosphere, the satisfaction of TBL lectures was significantly higher than that of self-study lectures (P< 0.001). 93.3% (14/15) of the residents preferred TBL lectures. Conclusions: The combination of ophthalmology clinical guidelines and TBL teaching was proved to be an effective teaching model. The residents achieved excellent teaching results in the subjective satisfaction questionnaire and objective examination scores.
在晶状体纤维细胞分化的终末阶段，细胞核、线粒体、内质网及高尔基体等膜性细胞器会发生程序性的降解，这对晶状体透明性的维持至关重要。然而，晶状体细胞器降解过程的机制尚不明确。研究晶状体细胞器的降解过程可为阐明白内障的发病机制提供理论依据，也有望为晶状体再生提供新的干预靶点。本文就晶状体细胞器降解过程及其机制进行综述。
During terminal differentiation of lens fiber cells, nuclei and other organelles experience programmed elimination.This process is essential for the maintenance of lens transparency. However, the mechanisms underlying lens organelle degradation remain unclear. Identification of the mechanisms can provide a theoretical basis for elucidating the pathogenesis of cataract and is expected to reveal new intervention targets for lens regeneration. In this review, we discuss potential mechanisms and the process of lens organelle degradation.
眼睛是人体最重要的感觉器官之一，主要由角膜和晶状体构成的屈光系统和视网膜构成的视觉神经系统2个部分构成。眼睛各组织的发育和功能异常都可影响视功能，甚至致盲。现有的致盲眼病的治疗方式均存在各自瓶颈问题，新的诊治方法亟待开发。近年来，得益于干细胞和组织工程学的发展，结合现有眼各组织的发育理论知识，研究者们利用多种来源的干细胞在体外成功诱导出具有组织特异结构和功能的眼类器官。眼类器官研究为利用干细胞研究眼组织发育和眼病发病机制、药物筛选以及替代治疗创造了新机遇，将干细胞治疗眼病的转化研究推向了一个更高平台。本文将对现有眼类器官的技术发展及应用进行综述。
Being one of the most important sensory organs, the eye is composed of the cornea, the lens, which are responsible for refraction, and the retina, which is the neural sensory part of the eye. Various kinds of developmental abnormalities and functional defects could lead to visual dysfunctions, and even blindness. Current treatments for blindness-causing eye diseases all have their own limitations, awaiting new efficient diagnostic and treating methods. Thanks to the development in stem cell biology and bioengineering, taking advantage of the rich knowledge accumulated on the mechanisms governing eye development, researchers have successfully generated various ocular organoids using multiple sources of stem cells in vitro, which resemble their counterparts in vivo on both the structural level and functional level. Ocular organoids provide valuable material and models for studying eye development, pathology, drug screening, and cell replacement therapy, pushing translational studies of ocular stem cell to a new era. Here, the paper reviews the development and application of ocular organoid technologies.
