目的：调查中山大学中山眼科中心参加分子医学实验技能培训课程的研究生学员上课前的实验基础，为研究生实验技术课程的备课提供参考。方法：对2020年及2021年参加分子医学实验技能培训课程的博士和硕士研究生进行课前问卷调查。从理论知识和操作经验两方面对15个专题课程进行分析。结果：共155名学生完成问卷调查。在全部专业研究生中，25%以上学生对理论知识不了解的专题有14个，而仅有10%以下学生熟练操作的专题有6个；分子医学专业的优于前者，不了解和熟练掌握的专题个数分别是9和12。理论掌握程度最低的4个专题是细胞增殖、流式细胞、图像采集和组学分析。15个小专题整合成7个大专题，操作熟练程度由低到高依次是：眼科实验数据收集、组学技术、数据分析、细胞技术、蛋白技术、组织分析、分子技术。结论：新入学研究生存在分子医学实验技能基础理论知识薄弱以及科研训练不足等问题，迫切需要改善实验技能培训制度，深化课程体系建设。
Objective: To conduct a pre-course survey on the graduate students who participated in the Molecular Medicine Laboratory Skills Training Course in the Zhongshan Ophthalmic Center of Sun Yat-sen University to provide a reference for the preparation of the course. Methods: We asked the doctoral and master’s students who participated in the training courses of molecular medical experimental skills in 2020 and 2021 to take a pre-course questionnaire survey and analyzed the results by the students’ pre-course command of theoretical knowledge and pre-training operational experience in 15 lessons of special topics or techniques. Results: A total of 155 students completed the pre-course questionnaire survey. Our results showed that there were 14 lessons in which more than 25% of the students were not familiar with the theoretical knowledge, whereas there were 6 lessons in which less than 10% of the students had high operational proficiency. The students majoring in the molecular medicine had better prior knowledge of the techniques: there were only 9 lessons in which more than 25% of the students were not familiar with the theoretical knowledge, whereas there were 12 lessons in which less than 10% of the students had high operational proficiency. The four lessons with worst prior knowledge were cell proliferation, flow cytometry, image acquisition, and omics analyses. We grouped the 15 lessons into 7 categories: the ophthalmic experimental data collection, the omics technology, the data analyses, the cell technology, the protein technology, the tissue analyses, and the molecular technology, presenting by the level of the students’ pre-training proficiency from low to high. Conclusion: The first-year graduate students were very weak in basic knowledge and had little experience in techniques before joining the molecular medicine training courses. It is urgent to improve the laboratory skills training system and strengthen the construction of the curriculum system.
目的：调查干眼在郑州市机关工作者中的患病情况，分析相关危险因素，为有效防治干眼提供科学依据。方法：选取2019年9月到2020年9月在郑州大学第一附属医院体检的郑州市机关工作者873例。采用自行设计的一般资料问卷和OCULUS Jenvis-OSDI干眼问卷进行调查，记录评分结果，同时检查记录裂隙灯、角膜荧光素染色评分(corneal fluorescein staining score，FL)、基础泪液分泌实验(Schimier I test，SIT)、泪膜破裂时间(tear break-up time，BUT)测定结果。统计分析机关工作者干眼患病率与危险因素。结果：体检的873例郑州市机关工作者中360例诊断为干眼，干眼总患病率为41.24%，女性患病率(44.62%)明显高于男性(36.26%)，差异有统计学意义(P=0.014)。干眼问卷OSDI评分与FL评分呈正相关，BUT与SIT呈正相关，OSDI(和FL评分)与BUT(和SIT)呈负相关。Logistics多因素分析表明：干眼家族史、绝经、曾行眼部手术、滴眼液使用情况、长时间佩戴角膜接触镜、长时间操作视频终端、睡眠不足、糖尿病史是机关工作者干眼患病的危险因素(均P<0.05)，而饮酒是保护因素(P=0.001)。结论：机关工作者干眼患病率较高，危险因素囊括家族患干眼史、绝经、曾行眼部手术、滴眼液使用情况、长时间佩戴角膜接触镜、长时间操作视频终端、睡眠不足、糖尿病病史。加强干眼防治的宣传教育，针对不同危险因素提供眼健康指导并进行防控治疗，保护机关工作者的眼健康。
Objective: To investigate and analyze the prevalence of dry eyes in Zhengzhou office workers, and identify the related risk factors in order to provide evidence for effective prevention and treatment. Methods: We selected 873 cases of Zhengzhou office workers who had checkup in our hospital from September 2019 to September 2020 as the research subjects. They were investigated with self-designed general information questionnaire and OCULUS Jenvis-OSDI dry eye questionnaire and scores of the questionnaires will be assessed. At the same time,they underwent dry-eye-related inspections such as slit lamp examination, corneal fluorescein staining score (FL), Schimier I test (SIT) and tear break-up time (BUT) assessment. The prevalence and risk factors of dry eyes in these office workers were statistically analyzed. Results: Among 873 Zhengzhou office workers, 360 cases were diagnosed as dry eyes, and the total prevalence of dry eye was 41.24%. The female prevalence rate was 44.62%, which was significantly higher than that of male (36.26%, P=0.014). OSDI scores and FL scores were positively correlation as well as BUT and SIT, while OSDI (and FL) and BUT (and SIT) were negatively correlation. Logistic multivariate analysis showed that dry eyes family history, menopause, ocular surgery history, eye drops using, long time corneal contact lenses wearing, long time video terminal operating, lack of sleep and diabetes history were independent risk factors in office workers’ dry eye disease (all P<0.05), while drinking was protective factor (P=0.001). Conclusion: The dry eyes prevalence is high among office workers. The risk factors include dry eye family history, menopause, ocular surgery history, eye drops using, long time corneal contact lenses wearing, long time video terminal operating, lack of sleep and diabetes history. We should strengthen the publicity and education of the dry eye prevention and treatment, provide eye health guidance, prevention and treatment according to different risk factors, and protect the office workers’ eye health.
纳入126名中山大学临床医学五年制4年级学生，对其接受为期1周的直接检眼镜见习教学后，进行问卷调查，了解学生对直接检眼镜学教学的看法以及学习过程中的操作难点。结果显示大部分学生认为直接检眼镜对临床工作有重要作用。但学生普遍反映学习过程难度大，师生视野无法共享，进而阻碍了师生直接的教学沟通。多数学生愿意接受更进一步的直接检眼镜教学。
A total of 126 senior of 5-year clinical medicine students in Sun Yat-sen University were recruited. After 1-week internship and direct ophthalmoscope training, a questionnaire survey was conducted to scrutinize students’ feedback about the training methods and learning difficulties during the internship. The results showed that most students thought that the direct ophthalmoscope played an important role in clinical work. However, students generally felt complicated and hard during the learning process due to the communication obstacle between teachers and students caused by the unavailability of vision sharing. In spite of this, most students are still willing to accept further direct ophthalmoscopy training.
