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% vs 77.91%，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.

Objective: To compare the efficacy of bicanalicular silicone intubation assisted with epidural catheters and traditional bicanalicular silicone intubation in the anastomosis of lacrimal canaliculus rupture. Methods: Fifty-two patients (52 eyes) were randomly divided into two groups. Patients in group A (30 cases) were treated by bicanalicular silicone intubation assisted with epidural catheters, while patients in group B (22 cases) were treated with conventional operation (bicanalicular silicone intubation). The intubation time, average operation time, nasal bleeding rate, intraoperative pain score and one-time success rate were compared between the 2 groups. Results: Intubation time in group A was (11.20±3.80) min and that in group B was (21.50±12.60) min (P<0.05). The mean operation time of group A was (42.70±5.50) min and that of group B was (62.20±15.20) min (P<0.05). Intraoperative pain score was 3.10±0.80 in group A and 4.60±1.25 in group B (P<0.05). The rate of nasal hemorrhage was 3.33% (1/30) in group A and 18.2% (4/22) in group B (P<0.05). With respect to one-time anastomosis success rate assessment, the effective rate was 93.3% (28/30) in group A, and 86.4% (19/22) in group B (P>0.05). Conclusion: During lacrimal canalicular anastomosis, bicanalicular silicone intubation assisted with epidural catheters is superior to bicanalicular silicone intubation in intubation time, average operation time, nasal bleeding rate and pain degree. There is no significant difference between the two methods in one-time success rate. Bicanalicular silicone intubation assisted with epidural catheters is safe, reliable, and worthy of promotion.

Background: To analyze the morphological changes of meibomian glands in patients with recurrent and primary meibomian gland cyst under in vivo confocal microscope (IVCM). Methods: A cross-sectional study was performed in Shantou International Eye Center from September 2018 to April 2019. Ten patients with recurrent meibomian cyst, 10 patients with primary meibomian cyst and 10 control subjects were selected in this clinical trial. All subjects received routine ophthalmologic examination and IVCM examination. IVCM examination parameters included open area of meibomian gland, and the maximum and minimum diameter of meibomian gland opening. Relevant parameters were analyzed and statistically compared among different groups. Results: The average minimum diameter of meibomian glands opening in the recurrent meibomian gland cyst group was (109.08±49.96) μm, the average maximum diameter of meibomian glands opening was (144.95±68.10) μm, and the median open area of meibomian gland was 11 621.62 (3 976.49–24 828.82) μm2. In the primary meibomian gland cyst group, the average minimum diameter of meibomian glands opening was (101.53±29.55) μm, the average maximum diameter of meibomian glands opening was (130.08±45.21) μm, and the median open area of meibomian gland was 10 615.07 (5 813.29–18 275.44) μm2. The opening of meibomian glands in both the recurrent and primary meibomian gland cyst groups was enlarged, which significantly differed from that in the control group (both P<0.05). No statistical significance was noted between the recurrent and primary meibomian gland cyst groups (P>0.05). The acinus structure around the gland tube was manifested with serious hypertrophic scar complicated with inflammatory cell infiltration. Conclusion: IVCM can detect the morphological changes of meibomian glands in meibomian gland cyst patients. The IVCM findings of recurrent and primary meibomian gland cyst are different.

眼肌型重症肌无力(ocular myasthenia gravis，OMG)是一种累及神经肌肉接头突触后膜的自身免疫性疾病。OMG波动性的临床特征易导致较高的漏诊率和误诊率，严重影响患者的生活质量。因此，检测方法在早期确诊OMG中发挥重要作用。本文围绕临床检查、新斯的明试验、自身抗体检测、电生理检测等方面对OMG检测方法作一综述，以期为OMG的早期确诊提供有益的指导。

Ocular myasthenia gravis (OMG) is an autoimmune disease involving the postsynaptic membrane of the neuromuscular junction. The fluctuation of OMG and the clinical characteristics of fatigue easily lead to a high rate of missed diagnosis and misdiagnosis, which seriously affects the quality of life of patients. Therefore, detection methods play an important role in the early diagnosis of OMG. In this paper, OMG detection methods were reviewed in clinical examination, neostigmine test, autoantibody detection, electrophysiological detection, and other aspects, in order to provide useful guidance for the early diagnosis of OMG.

睑板腺功能障碍(meibomian gland dysfunction，MGD)是眼科常见疾病，是蒸发过强型干眼的主要原因。基于人群流行病学的调查显示：MGD亚洲的发病率为46.2%~69.3%。目前，MGD治疗的方式包括眼睑清洁、热敷、睑板腺按摩、人工泪液、抗生素等，其中热敷为常用的家庭治疗方法。由于不同的热敷方式、温度、时间、频次及依从性，导致应用热敷治疗MGD到目前为止还没有统一标准。另外，热敷的不良反应如视物模糊、皮肤烫伤等，也没有引起临床足够重视。因此，为提高热敷的临床疗效及减少其不良反应，未来进行热敷的规范化指导或治疗很有必要。

Meibomian gland dysfunction (MGD) is a common ophthalmic disease, which is the main cause of evaporative dry eye. Population-based studies have suggested that the prevalence of MGD is high in Asia, with a reported incidence of 46.2% to 69.3%. Current modalities of MGD treatment include lid hygiene, warm compresses, massage, artificial lubricants, systemic and topical antibiotics, etc., among which warm compress is a common at-home treatment. Due to different eyelid warming methods, temperature, durations of heat application, frequency and compliance, there is no uniform standard for the application of warm compress to the treatment of MGD. In addition, adverse events of warm compress, such as blurred vision and thermal damage, have not attracted enough attention in clinical practice. Therefore, in order to improve the clinical efficacy of warm compress and reduce its adverse events, it is necessary to conduct standardized guidance or treatment of warm compress in the future. Based on the above considerations, this article will briefly review the application of warm compress to the treatment of MGD.
