[摘 要] 视神经属于中枢神经的一部分,损伤后难以再生。视神经损伤通常伴随视网膜神经节细胞(retinal ganglion cells,RGCs)的持续性凋亡及视神经变性坏死,引起视力损害甚至完全失明。目前针对视神经再生的基础研究主要集中于保护和维持视神经损伤后RGCs的存活、促进RGCs轴突再生及重建视神经功能。本文以RGCs保护、轴突再生及视神经功能重建等为关键词,查询国内外最新视神经再生研究类文献,并分析整理,从抗氧化应激、提供外源性细胞因子、炎症刺激、抗胶质瘢痕、基因调控等方面阐述近年的视神经再生研究进展,以期对后续的基础研究开展及临床转化有所帮助。
Abstract Optic nerves are a part of the central nervous system, which is difficult to regenerate after injury. Optic nerve injury is usually accompanied by continuous apoptosis of retinal ganglion cells (RGCs) and degeneration or necrosis of optic nerves, resulting in visual impairment or even complete blindness. At present, the basic research on optic nerve regeneration mainly focuses on protecting and maintaining the survival of RGCs after optic nerve injury, promoting RGCs axon regeneration, and reconstructing optic nerve function. In this paper, RGCs protection, axon regeneration, and optic nerve function reconstruction are used as key words to collect the latest domestic and foreign literatures on optic nerve regeneration. The research progress of optic nerve regeneration in recent years was reviewed from the aspects of antioxidant stress, provision of exogenous cytokines, inflammatory stimulation, anti-glial scar, gene regulation and so on, in order to help the follow-up basic research and clinical translation.

Dry eye disease (DED) is a common chronic ocular surface disease. It can not only cause discomfort and damage to the eyes but also easily lead to psychological disorders in patients. The most common psychological disorders related to DED are anxiety, depression and sleep disorder. To alleviate the condition of DED, in addition to active treatment for DED itself, it is also necessary for the patients to maintain a healthy psychological state. Therefore, attention should be paid to the pathogenesis, prevention and treatment measures of DED-related anxiety, depression and other psychological disorders.

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.

Objective: To evaluate the changes of visual fatigue symptoms, accommodative functions, ocular surface conditions, and high-order aberrations (HOA) after implantation of implantable collamer lens (ICL), and to explore their effects on asthenopia. Methods: It was a prospective observational case series. Patients with ametropia who underwent ICL surgeries and completed 3-month follow-up in our hospital were enrolled.Asthenopia scores, amplitude of accommodation (AA), positive/negative relative accommodation (PRA/NRA),accommodative facility (AF), the ratio of accommodative convergence and accommodation (AC/A), Schirmer test, non-invasive breakup time (NBUT), and HOA were examined before surgeries and at 1 week, 1 month and 3 months after surgeries, then statistically analyzed. Results: Symptoms of asthenopia were significantly worse at 1 week after ICL surgeries than those before surgeries, but increased gradually as time went by, eventually recovered at 3 months postoperatively. Among regulatory indicators, AA decreased 1 week postoperatively, but was significantly higher at 1 and 3 months after surgeries; AF was lower 1 week after surgery than baseline, slightly better at 1 month postoperatively, and significantly higher at 3 months postoperatively; PRA and NRA had no significant change; AC/A decreased 1 week after surgeries, returned to the baseline at 1 month postoperatively, and increased 3 months postoperatively. Tears and meibomian gland function index: NBUT values at 1 week, 1 month and 3 months after surgeries were significantly decreased compared with those before surgeries, and NBUT at 1 week postoperatively was the lowest; Schiermer values had a slight decrease at 1 week after surgeries, and basically recovered at 1 and 3 months after surgeries. HOA after surgeries were increased compared with those before surgeries, but there was no significant change between each time point. Correlation analysis showed that the lower AF and NBUT after ICL surgeries, the more severe the asthenopia symptoms. Conclusion: The symptoms of asthenopia aggravated transiently after ICL implantation surgeries, but improved gradually with time. AF and NBUT were important factors affecting the changes of asthenopia.

近年来,眼科手术后的疼痛受到关注,部分患者术后表现出疼痛区域扩大,神经性畏光。术后这种 对伤害性刺激性信号反常性增加的现象称之为痛觉过敏。痛觉过敏的发展会导致患者延迟术后恢 复等问题。此外,痛觉过敏还会引起患者不适,诱使患者使用更多的止痛药而产生相关的不良反 应。而TRPV1/TRPA1是一种伤害性感受器,能够被伤害性刺激特异性激活而诱发痛觉过敏。尽管 如此,目前关于眼科术后的痛觉过敏发病机制未完全阐明,TRPV1如何增敏导致痛觉过敏的分子生 物学过程尚未明确。
The postoperative pain of ophthalmic surgery has been widely concerned in recent years. Some patients show enlarged painful areas and neurophotophobia postoperatively. This abnormal increase in noxious irritant signals after surgery is called hyperalgesia. The development of hyperalgesia can result in delayed postoperative recovery for patients. In addition, hyperalgesia can also cause discomfort for patients, and induce patients to use more analgesics, which can have related side effects. TRPV1/TRPA1 is a nociceptor, which can be specifically activated by nociceptive stimuli to induce hyperalgesia. Nevertheless, the pathogenesis of hyperalgesia after ophthalmology surgery has not been fully elucidated, and the molecular signal pathway of how TRPV1 sensitizes and causes hyperalgesia is not yet clear.

Objective: To evaluate the safety and efficacy of dexmedetomidine combined with sufentanil for postoperative patient-controlled intravenous analgesia (PCIA) after transscleral diode laser cyclophotocoagulation (TDLC) in elderly patients with glaucoma. Methods: Eighty elderly glaucoma patients undergoing TDLC were selected and randomly divided into a SD group (n=40) and a S group (n=40) by random number table method. In SD group (n=40), sufentanil 1.5 μg/kg, dexmedetomidine 1.5 μg/kg and tropisetron 4 mg were used for postoperative PCIA, and sufentanil 2 μg/kg and tropisetron 4 mg were used in S Group (n=40). The corresponding drugs in saline solution was added into 100 mL solution with electronic analgesia pump. PCIA was performed immediately after the operation until 24 h after the operation. The basic condition and operation situation of the two groups were observed and compared, and systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), NRS pain score, Ramsay sedation score and non-operation eye intraocular pressure (IOP) at preoperative (T0), after operation (T1), postoperative 6 h (T2), 12 h after operation (T3) and 24 h after operation (T4) were compared, and postoperative adverse reactions such as nausea and vomiting, respiratory depression, restlessness and use of other auxiliary analgesic drug were also compared. Results: There was no significant difference between two groups of patients’ basic and surgical conditions. There was no significant difference between two groups at each time point DBP, non-operation eye IOP and NRS score. SBP at T3 and T4, HR at T2, T3 and T4, and Ramsay score at T2 and T3 in SD group were lower than the S group, the difference was statistically significant. There was no significant difference in the total number of adverse reactions between two groups, but the incidence of nausea and vomiting and restlessness in group SD were lower than those in group respectively, the difference was statistically significant (P<0.05). There was no significant difference between the two groups in the incidence of respiratory depression, dizziness, lethargy and the use of other auxiliary analgesics. The sufentanil usage in group SD was lower than that in group S (P<0.05). Conclusion: PCIA with dexmedetomidine 1.5 g/kg combined with sufentanil 1.5 g/kg does not affect the non-operation eye IOP. It can be safely and effectively applied to postoperative analgesia for elderly patients with glaucoma after TDLC
