Objective: To explore the application effect of standardized training and assessment of emergency nursing skills in ophthalmology nurses. Methods: We implemented standardized training and assessment of emergency nursing skills for 142 ophthalmology nurses in our hospital, compared the difference between the first aid theory and the first aid skill operation before and after the training, and used a self-made questionnaire to conduct training evaluation surveys. Results: After implementing the standardized training of emergency nursing skills, the assessment scores of first aid theory and skill operation of ophthalmology nurses were higher than those of the pre-training assessment. And the difference was statistically significant (P<0.05). More than 90% of ophthalmology nurses had a positive opinion on first aid training. Conclusion: Standardized training and assessment of emergency nursing skills have improved the clinical emergency nursing level of ophthalmology nurses and cultivated a good emergency nursing awareness and teamwork spirit. At the same time, they have strengthened nurses’ self-worth and professional identity, and achieved better training results.

Dry eye is one of the most common ocular surface diseases. It is characterized by a loss of homeostasis of the tear film, and accompanied by ocular symptoms, in which tear film instability and tear hyperosmolarity, ocular surface inflammation, and neurosensory abnormalities play major etiological roles. Diquafosol tetrasodium is a purinergic P2Y2 receptor agonist that promotes mucin and aqueous tear secretion. The unique pharmacological mechanism of diquafosol tetrasodium opens up a new direction for the medical therapies of dry eye. This article reviews the clinical therapeutic effect and research progress of diquafosol tetrasodium for the past few years.
目的：了解八年制医学生对全程导师的教学需求与满意度。方法：将中山大学八年制临床医学生分为低年级、高年级两组，均进行匿名线上问卷调查。分析问卷结果，并比较两组间的不同。结果：回收问卷352份。学生对导师个人“比较满意”占比高(低年级45.56% vs 高年级37.79%，P=0.087)，对全程导师制度“比较满意”占比高(低年级 36.67% vs 高年级33.14%，P=0.806)。对全程导师制度“很了解”与“比较了解”的学生在低年级中明显低于高年级的占比(16.67% vs77.91%，P<0.001)。低年级学生期待全程导师在职业规划、临床思维、科研思维、心理健康发挥较大影响的占比均高于高年级的实际评估(构成比4个方面均P<0.001，选择“有很大影响”及“比较有影响”在低、高年级占比分别为83.33% vs 36.63%，92.22% vs 29.07%，91.67% vs 31.39%，62.78% vs 38.37%)。结论：学生对全程导师个人及制度均较满意，但存在低年级对该制度了解少、师生联系少、导师实际作用低于学生预期、科研训练机会不足等问题。亟需完善全程导师制，推动临床医学高水平人才的培养。
Objective: To evaluate the teaching needs and satisfaction of the eight-year program medical students to the whole-course tutors. Methods: An anonymous online questionnaire survey was conducted among the eight-year program medical students at Sun Yat-sen University. All students were divided the junior group and the senior group, and the differences between the two groups were compared. Results: A total of 352 valid questionnaires were collected. The proportion of students who were fairly satisfied with their whole-course tutors was 45.56% in the junior group and 37.79% in the senior group (P=0.087). The proportion of students who were fairly satisfied with the whole-course tutorial system was 36.67% in the junior group and 33.14% in the senior group (P=0.806). The proportion of students who “know well” and “know fairly well” about the whole-course tutorial system in the junior group was significantly lower than that in the senior group (16.67% vs 77.91%, P<0.001). The proportion of students in the junior group expecting their whole-course tutors “having a great impact” or “having some impact” on career planning, clinical thinking, scientific research thinking and mental health was significantly higher than that in the senior group (tests for proportions, all P<0.001, 83.33% vs 36.63%, 92.22% vs 29.07%, 91.67% vs 31.39%, 62.78% vs 38.37%). Conclusion: The eight-year program medical students are satisfied with their whole-course tutors and the whole-course tutorial system. However, some problems still exist, such as lower grade students lack of understanding of the whole-course tutorial system, insufficient contact between tutors and students, the actual influences of tutors failing to meet the students’ expectation, and insufficient opportunity of scientific research and training. It is urgent to improve the whole-course tutorial system and promote the cultivation of qualified medical talents.

Fungal keratitis is a significant cause of corneal blindness in tropical and subtropical countries. With the development of modern medicine, the cure rate of early fungal keratitis has been significantly improved after medical or surgical treatment. However, due to the lack of timely and reasonable treatment for many patients with fungal keratitis, the disease has become difficult to treat and the prognosis is poor. With the efforts of numerous scholars, some new advances have been made in the treatment of recalcitrant fungal keratitis in recent years, such as antifungal drugs and administration methods. At present, the treatment methods of recalcitrant fungal keratitis have their own characteristics, advantages and disadvantages. It is necessary to understand the available antifungal therapies, their indications and side effects for the treatment of recalcitrant fungal keratitis.
