原发性干燥综合征(primary Sj?gren’s syndrome,SS)是一种主要累及外分泌腺体的自身免疫性疾病,患者通常因为严重的干眼症状首先就诊于眼科,大多数临床医师对原发性干燥综合征相关性干眼(Sj?gren’s syndrome dry eye disease,SS-DED)认识不足,可能导致漏诊和误诊。侵入性极小的客观检查及生物标志物的发展,将有助于发现SS-DED的真面目,并可能从新的角度阐释其发病机制,为其诊断、分类及治疗提供新的思路。SS-DED的治疗没有特效的药物,大多数患者需接受多种方法的治疗,以了解哪些方法最有效。
Primary Sj?gren’s syndrome is an autoimmune disease that mainly affects exocrine glands. Patients usually refer to ophthalmologists because of severe dry eye symptoms. Most clinicians have insufficient knowledge with dry eye disease associated with primary Sj?gren’s syndrome probably leading to misdiagnosis or missing the diagnosis.The diagnosis of Sj?gren’s syndrome dry eye disease (SS-DED) is difficult, but the extremely invasive objective examination and the development of biomarkers will help to understand this disease and explain its pathogenesis from a new perspective. There is no specific treatment for the SS-DED, and most patients should receive multiple treatments to select the optimal treatment.

微RNA-26b(microRNA-26b,miR-26b)是miR-26家族中的一员,作为基因表达调控因子,在细胞代谢、增殖、分化、凋亡、自噬、侵袭、转移等生物学过程中均发挥着重要的调控作用。近年来,随着对miR-26b研究的深入,研究者认识到miR-26b稳定存在于角膜、结膜上皮、晶状体、睫状体、小梁网、房水、玻璃体和视网膜等眼部组织中,且有越来越多的研究证实miR-26b在眼科疾病,例如翼状胬肉、白内障、增生性玻璃体视网膜病变、增生型糖尿病视网膜病变、年龄相关性黄斑变性等疾病的发生和发展中有着重要的调控作用。该文对近年miR-26b在眼科疾病方面的研究进行了综述,为探讨miR-26b在眼科疾病中发挥作用过程中的分子机制提供理论基础。
MicroRNA-26b (miR-26b) is a member of the miRNA-26 family. As a gene expression regulator, it plays an important regulatory role in biological processes such as cell metabolism, proliferation, differentiation, apoptosis, autophagy,invasion and metastasis. In recent years, with the in-depth study on miR-26b, researchers found that miR-26b stably exists in the cornea, conjunctival epithelium, lens, ciliary body, trabecular meshwork, aqueous humor, vitreous, retina and other ocular tissues. More study results confirmed that miR-26b acted on eye diseases, and played an important regulatory role in diseases occurrence and development, such as pterygium, cataract, proliferative vitreo retinopathy,proliferative diabetic retinopathy, age-related macular degeneration, etc. This article reviews the research progress of miR-26b in eye diseases recently, to provide a theoretical basis on molecular mechanisms involving in the role of miR-26b in eye diseases.
甲氨蝶呤(Methotrexate,MTX)是一种叶酸类似物,具有抗增殖、抗炎和免疫调节作用。在临床上广泛用于治疗多种疾病,包括恶性肿瘤和自身免疫性疾病。MTX通过眼局部注射或者全身给药用于眼科疾病的治疗,其安全性和有效性均已被证实。其中玻璃体腔注射可以减少糖皮质激素及免疫抑制剂的全身使用,在眼科的应用越来越广泛。MTX在备孕期男性及女性、妊娠期妇女、哺乳期妇女、儿童、青少年及老年人等特殊患者人群中的应用有其特殊性,用药情况因患者而异。低剂量MTX常见不良反应包括胃肠道症状、肝功能异常等,比较少出现严重的不良反应,但仍应做好药学监护。该篇综述总结MTX的临床使用方法及其不良反应,为其在眼科的临床应用提供参考。
Methotrexate (MTX) is a folate analog with anti-proliferative, anti-inflammatory and immunomodulatory effects.It is widely used in clinical practice to treat various diseases, including malignant tumors and autoimmune diseases.MTX is used for treating eye diseases by local injection or whole-body administration. Its safety and efficacy have been confirmed. The intravitreal injection can reduce the whole-body use of glucocorticoids and immunosuppressive agents, so it is applied in ophthalmology increasingly. The specificity of MTX has been found in its application in special patients, such as men and women in pregnancy preparation period, pregnant women, lactating women, children, adolescents and the elderly. The dosage varies from patient to patient. Common adverse reactions to low-dose MTX include gastrointestinal symptoms, liver dysfunction, etc. Serious adverse reactions are relatively rare, but pharmaceutical monitoring is still necessarily needed. This review summaries the usage and adverse reactions of MTX in clinical practice, to provide reference for its application in clinical practice in ophthalmology.
术前有效杀灭或减少眼表微生物的数量是降低术后眼内炎的重要措施。聚维酮碘消毒液和妥布霉素均能有效的降低眼科手术术后眼内炎发生率。笔者通过文献报道,综合分析聚维酮碘消毒液及妥布霉素滴眼液及注射液对眼科手术结膜囊微生物的控制能力,为眼科手术术前准备提供理论依据。
Effectively killing or reducing the number of ocular microbes before surgery is an important measure to reduce postoperative endophthalmitis. Both povidone-iodine disinfectant and tobramycin can effectively reduce the incidence of endophthalmitis after ophthalmic surgery. Through literature reports, the author comprehensively analyzes the control ability of povidone-iodine disinfectant and tobramycin eye drops and injection on the microscopy of conjunctival sac in ophthalmic surgery, and provides theoretical basis for preoperative preparation of ophthalmic surgery

Objective: To compare the operation status and occupational exposure to needle stick injuries level of nursing staff before and after the promotion of nursing standard prevention operation procedure (SOP), and to explore the practicability and effectiveness of nursing SOP. Methods: Before and after the promotion of nursing SOPs at Zhongshan Ophthalmology Center of Sun Yat-sen University, 14 responsible nurses were assessed for operation,and the number of infectious diseases and occupational exposures to needle stick injuries before and after the promotion of nursing SOPs were compared. Results: The average scores of operation and evaluation before and after the implementation of nursing SOP were 82.31 points and 88.23 points, with significant statistical difference(P<0.001). There was no statistical difference in the results of the initial senior responsible nurses. The total number of patients with blood infectious diseases before and after the implementation of nursing SOP was 32 cases and 51 cases. The occupational exposure to needle stick injuries events were 4 cases and 0 and the difference was statistically significant (χ2 =6.698, P=0.020). Conclusion: The promotion of standard preventive procedures can enable caregivers to strengthen self-protection, reduce occupational exposure, and effectively reduce the rate of iatrogenic infection.
目的:探讨眼科住院医师规范化培训中睑板腺囊肿诊疗的培训效果及存在的问题,以期改进培训方式。方法:以2020年4月在中山大学中山眼科中心培训的154名学员为对象,进行问卷调查,采用SPSS 20.0统计学软件进行数据分析。结果:共76名专业型硕士(专硕)、78名住院医师培训(住培)学员完成了问卷调查。专硕具有睑板腺囊肿诊断、保守治疗及手术主刀经验的比例分别为40.8%、11.8%、7.9%;住培则显著高于前者,分别为79.5%(P<0.001)、60.3%(P<0.001)和21.8%(P=0.016)。对于关键诊疗环节的判断,90.8%的专硕选择了临床诊断(P=0.007),94.9%的住培则选择治疗方案(P<0.001)。去除囊壁、术中意外与破溃皮肤的处理是专硕难以掌握的手术步骤(P<0.001);而住培仅为去除囊壁(P<0.001)。结论:睑板腺囊肿诊疗水平在眼科住院医师规范化培训中亟待提高,并根据各类型学员的临床能力和认知差异,进行分级分类培训。
Objective: To explore the teaching effect of diagnosis and treatment on chalazion in the standardized training of ophthalmology residents and its existing problems, in order to improve the quality of the training systems. Methods: A self-designed questionnaire survey was conducted with 154 ophthalmology residents in Zhongshan Ophthalmic Center in April 2020, and the investigative data was analyzed using SPSS 20.0. Results: Totally 76 medical postgraduates and 78 ophthalmology residents completed the questionnaire survey. The proportions of medical postgraduates who had individual experience on diagnosis, conservative and surgical treatment of chalazion were 40.8%, 11.8%, and 7.9%. Compared to the former, ophthalmology residents had significantly higher proportion, with 79.5% (P<0.001), 60.3% (P<0.001), and 21.8% (P=0.016), respectively. For judging the important aspect of diagnosis and treatment process, the medical postgraduates chose the clinical diagnosis (90.8%) (P=0.007), while the ophthalmology residents paid more attention on treatment options (94.9%) (P<0.001). In the surgical procedures, removal of cyst wall, management of intraoperative accidents and skin ulcers are all their difficult skills to master for medical postgraduates (P<0.001), while only removal of cyst wall for residents (P<0.001). Conclusion: The training level of diagnosis and treatment of chalazion still needs to be improved in the standardized training of ophthalmology residents. The training should be carried out according to the clinical competence and cognition differences of various types of students.

目前Wetlab眼科手术教学采用猪眼球作为教学模型,与实际手术差别较大,且无法满足外眼手术教学的需求。通过使用带有眼球、眼外肌、眶组织、眶骨及眼睑结构的全眼模型,可高度模拟真实手术场景,覆盖更多眼科手术教学需求。基于全眼模型构建多个眼科手术教学平台,依照培养阶段设计手术课程,创建新的评价体系,改变传统将“内眼”“外眼”分开的教学理念,可使年轻医师从一开始就建立眼科“分科而不分割”的整体思维,从而使眼科手术培训更加规范和完善。
Porcine eyes have been used as animal model in ophthalmic surgery training. However, it differs greatly from real surgery and cannot meet the needs of external eye surgery teaching. Porcine orbit model with eyeball, extraocular muscles, orbital tissue, bones and eyelids can be more realistic simulation of real surgeries and cover more needs for ophthalmic surgery teaching. By setting up ophthalmic surgery teaching platforms, designing staged course and creating new assessment methods based on porcine orbit model, the traditional concept about separation of internal and external eye is changed. This helps young doctors to establish a holistic view from the very beginning,that ophthalmic surgeries should not be split because of subspeciality. In this way, ophthalmic surgery training will become more standardized and perfected.
