目的：探讨小剂量利妥昔单抗(rituximab, RTX)预防视神经脊髓炎谱系疾病(neuromyelitis optica spectrum disorder, NMOSD)复发的有效性和安全性。方法：采用前瞻性自身对照试验，选取2020年7月至2021年4月临床确诊为NMOSD的38例患者进行研究，给予小剂量RTX治疗。所有患者均进行病史采集、眼科检查和血清学指标检测，记录NMOSD年复发率(ARR)、最佳矫正视力(BCVA)、合并自身抗体情况和追加治疗的情况。视力检查采用Snellen视力表进行，并将结果转换为最小分辨角对数(logMAR)视力记录。随访至少12个月（17.29±2.2）个月，以末次随访为疗效判定时间点，比较治疗前后ARR、BCVA；分析复发与发病年龄、是否合并自身免疫抗体阳性和患自身免疫性疾病的关系。记录不良反应的发生率和追加治疗的时间。结果：共38例患者61眼纳入研究。其中男性4例，女性34例。发病年龄12~60岁，中位发病年龄23 (18~29.3)岁。病程10.0~265个月，中位病程65 (48.3~101.0)个月。治疗前logMAR矫正视力(1.15±0.13)，治疗后logMAR矫正视力(1.54±0.39)，比较差异无统计学意义(t=1.120，P=0.267)。治疗前ARR(1.50±0.86)次/年，治疗后ARR降低为(0.12±0.07)次/年，比较差异有统计学意义(t=8.304，P<0.001)。追加治疗时间为(6.4±2.3)月。随访期间3例患者复发，复发次数为 5次。 复发者与未复发者的发病年龄、合并免疫抗体阳性比例、合并自身免疫性疾病比例比较，差异均无统计学意义(均P>0.05)。38例患者中，出现输注不良反应7例，给予减慢RTX滴速及加用地塞米松5 mg治疗后均缓解，随访期间未见其他明显不良反应。结论：小剂量RTX可以有效清除B淋巴细胞，预防NMOSD复发，且安全性较好。
Objective: To evaluate the efficacy and safety of long-term treatment with low-dose rituximab for neuromyelitis optica spectrum disorders (NMOSD). Methods: A prospective self-control study. A total of 38 patients who were diagnosed with NMOSD from July 2020 to April 2021 were recruited for rituximab treatment. All patients collected medical history, ophthalmic examination and serological test. Recorded the annual recurrence rate (ARR), best corrected visual acuity (BCVA), combined autoantibodies and therapy times after the first treatment. The BCVA was examined using Snellen chart, and converted to logMAR. The patients were followed up at least 12(17.29±2.2) months, and the last follow-up was taken as the time point of efficacy evaluation. ARR and BCVA before and after treatment were compared. To analyze the relationship between relapse and age of onset, combination of autoimmune antibodies and autoimmune diseases. The incidence of side effects and duration of additional therapy were recorded. Results: A total of 38 NMOSD patients (4 male/34 female, 61 involved eyes) were included in this study. The ages of onset age were 12-60 years, the median onset age was 23 (18~29.3) years. Duration of disease was 10.0~265 months, the median duration was 65 (48.3~101.0) months. Before treatment, the mean BCVA was 1.15 ± 0.13 , the mean BCVA at last follow-up was 1.54 ± 0.39, which was no significant difference (t=1.120, P=0.267). The mean ARR before and after treatment were 1.50±0.86 and 0.12 ± 0.07, respectively, with significant difference (t=8.304, P<0.001). The mean reinfusion period was 6. 4±2.3 months. Five relapses in 3 patients were observed. There were no significant difference between relapsed patients and non-relapsed patients on onset age, with/without auto-immune antibody ratio, with/without auto-immune diseases ratio (all P>0.05). Of 38 patients, 7 patients had side effects, all patients who had side effects, slowing down the infusion speed of RTX or infusing 5 mg of dexamethasone could relieve the discomfort. Conclusions: Low-dose RTX can effectively clear B lymphocytes, prevent NMOSD recurrence and with good safety.
目的：探讨超声乳化晶状体吸除联合囊袋上经巩膜缝线固定人工晶状体(intraocular lens,IOL)植入术治疗球形晶状体(microspherophakia,MSP)的有效性和安全性。方法：采用回顾性分析，选取2019年1月至 2020年6月期间在复旦大学附属眼耳鼻喉科医院进行治疗的MSP患者37例(37眼)，随机分为两组，纳入行超声乳化晶状体吸除联合囊袋上巩膜缝线固定IOL植入术(supra-capsular and scleral-fixated intraocular lens implantation,SCSF-IOL)的MSP患者20例(20眼)和行超声乳化晶状体吸除联合改良型囊袋张力环植入术(transscleral-fixated modified capsular tension ring and in-the-bag intraocular lens implantation,MCTR-IOL)的MSP患者17例(17眼)，观察两组术后最佳矫正视力及并发症等情况。结果：两组术后最佳矫正视力比术前均有改善(P<0.001)，而组间比较差异无统计学意义(P=0.326)。两组的IOL倾斜度相当(P=0.216)。预防性Nd:YAG激光后囊膜切开术在SCSFIOL术后1周至1个月进行。在SCSF-IOL组，2眼(10.00%)需要重复激光治疗，1眼(5.00%)出现囊口偏心。后囊膜混浊是MCTR组最常见并发症(6眼,35.29%)。随访期间两组均未出现IOL脱位、继发性青光眼和视网膜脱离。结论：SCSF-IOL是治疗球形晶状体的简单易行的手术方式，疗效与MCTR-IOL相当。Nd:YAG激光后囊膜切开术是预防SCSF-IOL术后囊袋并发症的必要手段。
Objective: To investigate the efficacy and safety of phacoemulsification combined with supra-capsular and scleral-fixated intraocular lens (IOL) implantation in the treatment of microspherophakia (MSP). Methods: by retrospective analysis, 37 MSP patients (37 eyes) who were treated in our hospital from January 2019 to June 2020 were randomly divided into two groups, including 20 MSP patients (20 eyes) who treated by SCSF-IOL and 17 MSP patients (17 eyes) who treated by transscleral-fixated modified capsular tension ring and in-the-bag intraocular lens implantation (MCTR-IOL). The best corrected vision and complications were observed. Results: the best corrected vision was significantly improved in both groups (P < 0.001), but there was no remarkable difference between the two groups (P = 0.326). The IOL tilt was also comparable (P = 0.216). Prophylactic Nd: YAG laser posterior capsulotomy was performed from 1 week to 1 month after the SCSF-IOL procedure. In the SCSF-IOL group, two eyes (10.00%) needed repeated laser treatment, and one eye (5.00%) had a decentered capsule opening. Posterior capsular opacification was the most common complication (6, 35.29%) in the MCTR group. No IOL dislocation, secondary glaucoma, or retinal detachment was observed during follow-up. Conclusions: SCSF-IOL is a simple and viable surgical option for managing MSP and is comparable with the MCTR-IOL. Nd: YAG laser posterior capsulotomy is a necessary mean to prevent residual capsule complications after the SCSF-IOL procedure.

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.
