Objective: To understand the infection status of four blood-borne pathogens among ophthalmology patients in South China and the distribution of positive patients across different eye diseases. Methods: A retrospective analysis of data from outpatient and inpatient or surgical ophthalmic patients who underwent screening for hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (anti-HCV), treponema pallidum antibody (anti-TP) and human immunodeficiency virus antibody (anti-HIV) at Zhongshan Ophthalmic Center of Sun Yat-sen University from January 2017 to December 2023. The positivity rates of these markers were recorded and analyzed. Results: A total of 253246 patients were included in the study, with positivity rates for HBsAg, anti-HCV, anti-TP, and anti-HIV at 9.00%, 0.45%, 1.55% and 0.13%, respectively. Among these, 686 patients tested positive for two or more markers, with the highest co-positivity observed for HBsAg and anti-HCV (57.29%), followed by anti-HIV and anti-TP (15.74%). The positivity rate of HBsAg showed a yearly decline, while the rates for anti-HCV, anti-HIV, and anti-TP remained relatively stable from 2017 to 2023. Males had significantly higher positivity rates for HBsAg, anti-HCV, anti-TP, and anti-HIV compared to females (P < 0.001). Significant differences in positivity rates for these markers were also observed across different age groups (P < 0.001). In patients with positive HBsAg, anti-HCV, and anti-TP, the proportion of cases with lens diseases were the highest, at 36.72%, 39.12%, and 46.97%, respectively. Vitreoretinal diseases followed, with proportions of 22.52%, 19.65%, and 19.69%, respectively. Among patients with positive anti-HIV, the proportion of cases with vitreoretinal diseases was the highest, at 42.99%, followed by lens diseases at 26.17%, and uveitis at 8.72%. Conclusions: This study reveals the infection status of four blood-borne pathogens in ophthalmology patients and the distribution of infected patients across different eye diseases, which is significant for assessing the risks of ophthalmic surgery and formulating infection control measures.

原发性干燥综合征 (primary Sjogren' 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 (Sjogren' 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 Sjogren' 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 Sjogren' s syndrome probably leading to misdiagnosis or missing the diagnosis. The diagnosis of Sjogren' 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.

Objective: The entrusted standardized training for residents is an important measure to gear the medical education in China to the international conventions. In this study, the effectiveness of standardized training for entrusted ophthalmic residents in China was evaluated both objectively and subjectively. Methods: Nine ophthalmic residents, commissioned by Shenzhen government of Guangdong Province, studied at Zhongshan Ophthalmic Center, Sun Yat-sen University during August 2012 to July 2015 were included in this study. The objective indicators of all participants were analyzed, including the basic information, clinical training, the score of examination, etc. The subjective self-assessment was also implemented thought a questionnaire including 13 designed questions.Results: All 9 participants included 2 males and 7 females, 2 medical masters and 7 bachelors, and the mean age was 26±3 years. Seven of them graduated from the national key medical universities. The mean number of rotated sub-clinical departments was 10.3, the mean number of managed inpatients and the participated operations were 736 and 1,219, respectively. The total number of managed outpatients was 6,274 in average. All participants completed at least one review article. Eight (88.89%) participants could independently diagnose and treat the most common ophthalmic diseases, they also could complete the basic clinical ophthalmic operation independently. Five (55.56%) participants could independently manage the pterygium excision, curettage of chalazion, anterior chamber penetration, etc. And 6 (66.67%) of the participants believed that the training length was reasonable. Eight (88.89%) of them were satisfied with the standardized training for residents on the whole. Finally, 7 participants successfully passed the first stage of standardized training program in Sun Yat-sen University. Conclusion: There was a high level acceptance rate of the standardized training programs for entrusted ophthalmic residents. The participants achieved the expected training effects, and could managed the diagnosis and treatment of common ophthalmic diseases independently. But the training effects and passing rate of examination were partly affected by the learning ability of the training students.

眼科日间手术显著提高了医疗效率、节约了医疗资源，眼科麻醉复苏体系的建立则是眼科日间全身麻醉手术的重要安全保障，也是提高眼科手术室效率的重要举措。在眼科手术结束后，全身麻醉患者被即刻转运至麻醉恢复室(post-anesthesia care unit, PACU)，此时患者仍处于麻醉状态，密切的监测和呼吸机辅助通气是必不可少的，从而保障患者从麻醉状态逐渐恢复至清醒状态。当患者清醒后，拔除喉罩，各项监测指标达到PACU的转出标准，可进入到Ⅱ期复苏并日间手术离院。然而，在PACU复苏期间，患者易出现喉罩移位、呛咳等引起急性缺氧等呼吸道不良事件的发生，小儿患者则由于术后眼罩遮盖等原因，出现苏醒期躁动的概率高，从而影响到患者顺利转出PACU，间接影响到手术患者的周转。因此，如何预防这些并发症的发生，对提高眼科麻醉复苏质量显得十分重要。
