目的： 探讨EZ Prep清洗液替代二甲苯进行手工脱蜡制作特殊染色片的效果。 方法: 应用EZ Prep清洗液替代二甲苯脱蜡，选取中山大学中山眼科中心临床病理科石蜡标本100例进行回顾性研究，常规切片后切片一式两份，分别采用传统二甲苯和EZ Prep清洗液手工脱蜡后按实验室标准化操作流程进行特殊染色，并比较脱蜡时间和染色效果。 结果： EZ Prep清洗液手工脱蜡处理的切片在革兰染色(Gram's)、六胺银染色(GMS)、过碘酸—雪夫染色(PAS)、马松(Masson)三色染色、刚果红等多种特殊染色中的染色质量和二甲苯脱蜡处理的效果一致，两组间染色片优良率比较差异无统计学意义(Z=0. 32，P＞0. 05)，且平均脱蜡时间由(33.0±2.7) min缩短至(7.2±1.1) min，加快了染色出片时间。结论：EZ Prep清洗液可以替代二甲苯在眼组织特殊染色中脱蜡，并具有脱蜡时间短、环保的优点，值得推广应用。
Objective: To investigate the effect of EZ Prep cleaning solution as an alternative to xylene for manual deparaffinization in the preparation of special staining slides. Methods: EZ Prep cleaning solution was utilized to replace xylene for deparaffinization in a retrospective study involving 100 paraffin-embedded specimens from the Clinical Pathology Department of Zhongshan Ophthalmic Center, Sun Yat-sen University. Routine sections were prepared and duplicated, with one set deparaffinized using traditional xylene and the other using EZ Prep cleaning solution. Subsequent special staining was performed following standardized laboratory protocols. Deparaffinization time and staining outcomes were compared. Results: Slides treated with EZ Prep cleaning solution for manual deparaffinization demonstrated staining quality comparable to xylene treatment across various special stains, including Gram's, GMS, PAS, Masson's trichrome, and Congo red. The difference in the excellent rate between the two methods is not statistically significant (χ 2 = 0.33, P > 0.05). Moreover, the average deparaffinization time is significantly reduced from 33.0±2.7 minutes to 7.2±1.1 minutes, thereby speeding up the staining process. Conclusion: EZ Prep could replace xylene deparaffinized sections in special staining of ocular tissues with the advantages of shorter deparaffinized time and environmental protection, which is worthy of promotion and application.

Objective: To investigate the utilization of environmentally-sustainable reagents in ophthalmic tissue pathology techniques. Methods: We prospectively collected 190 surgical specimens submitted to the pathology department of Zhongshan Ophthalmic Center between June 2023 and March 2024. Each specimen was divided into two sets, one treated with environmentally-sustainable reagents and the other with conventional reagents for fixation, dehydration, clearing, infiltration, staining, and mounting. The quality of histological sections from both groups was evaluated and compared. Results: Compared to the conventional reagent group, environmentally-sustainable reagent group showed good dehydration performance, moderately soft and hard tissue sections with intact cut surfaces and no cracks. H&E staining sections prepared with environmentally-sustainable reagents exhibited clear nuclear structures, distinct nuclear-cytoplasmic contrast, and clean backgrounds. The excellent section rates were 97.9% and 98.4% for the two, respectively. There was no significant difference in section quality between the two groups (Z = –0.645, P = 0.519). Tissue antigenicity was well-preserved during immunohistochemical procedures, with strong positive signals and accurate localization without background staining. Conclusions: The use of environmentally-sustainable reagents as a replacement for conventional reagents in the dehydration and staining of ophthalmic tissue yields satisfactory results, meeting the daily requirements for routine histological sectioning and staining. The entire process is xylene-free, environmentally-sustainable, cost-effective and worth being applied widely.

Objective: To investigate the clinical, imaging and pathological features of orbital extranodal marginal zone B cell lymphoma of mucosa-associated lymphoid tissue (MALT), so as to reduce misdiagnosis and improve survival rate.Methods: The clinical, imaging and histopathological data of 71 patients with orbital extranodal marginal zone B cell lymphoma of MALT who were treated in Zhongshan Ophthalmic Center, Sun Yat-sen University from Jan.2020 to Dec. 2020 were retrospectively analyzed. Results: There were 38 males and 33 females in the 71 patients.There were 31 cases located on the left orbit, 34 cases on the right orbit, and 6 cases were bilateral; there were 67 primary cases and 4 relapsed cases. The age ranged from 23 to 84 years old. The disease course ranged from 3 months to 15 years. The main clinical manifestations included ocular masses and limited eyeball movement.Magnetic resonance imaging showed a “cast-like” soft tissue shadow of uniform density, and no intraocular invasion is observed. Histopathological examination showed that the tumor was composed of small to medium sized lymphocyte-like cells. Tumor cells exhibited diffuse or lamellar growth, with small to medium-sized irregular nuclei, and the nucleoli were inconspicuous. Some of the lymphocyte-like cells showed mononuclear lymphoma cells changes, and plasmacytoid differentiation was observed in 9 cases, in which kappa and lambda expressions were asymmetric.Conclusion: The clinical manifestations of orbital extranodal marginal zone B cell lymphoma of MALT are various, and imaging examination has certain characteristics, which can assist preoperative diagnosis.Pathological examination can be used for accurate diagnosis and classification after operation, based on which appropriate treatment plan can be made and curative effect can be improved.
