Dermoscopic evaluation of normal canine skin with a handheld dermoscope
Veterinary Dermatology, Volume 36, Issue 5, Page 593-601, October 2025.Background – Dermoscopy is a noninvasive diagnostic tool that provides a magnified view of skin structures. While dermoscopy is described for certain canine dermatological diseases, large‐scale studies evaluating normal skin are lacking. Hypothesis/Objective – This study aimed to correlate dermoscopic findings with histopathological results in healthy ...

Effect of Benzalkonium Chloride on Corneal Epithelial Barrier Function and Possible Mechanisms of Benzalkonium Chloride Inhibiting Corneal Endothelial Gap Junction Intercellular Communication [PDF]
, 2015 第一部分：局部应用前列腺素类药物对兔角膜上皮细胞屏障功能的影响 目的：苯扎氯铵（BAK）是滴眼液中最常用的防腐剂之一，大量的临床研究发现，局部长期使用含BAK的眼部制剂会出现很多眼部不适症状。含BAK的前列腺素类药物是治疗开角性青光眼的一线药物，临床上患者往往需要长期使用，易导致眼睛干涩，结膜充血等等，然而其作用机制还不是非常清楚。紧密连接与粘着连接等构成了角膜上皮抵御外界病原微生物入侵的第一道生理屏障，对角膜正常生理功能的维持具有非常重要的作用 ...

Systematic Entomology, Volume 50, Issue 3, Page 495-518, July 2025.Using genomic data from 285 species across 19 planthopper families, we conducted the first phylogenomic study targeting global planthoppers and inferred their phylogeny with the highest resolution so far. We proposed taxonomic changes including the establishment of a new family Borysthenidae stat. rev. and a new superfamily Meenoploidea superfam.

Veterinary Dermatology, Volume 35, Issue 5, Page 479-491, October 2024.Background – Lop‐eared rabbits may be predisposed to otitis externa (OE) as a consequence of their ear conformation. Although otoscopy, otic cytological evaluation, and culture are valuable tools in dogs and cats, published data on rabbits remain lacking. Hypothesis/Objectives – This study aimed to assess the utility of otoscopy and cytological results

TNF induced RIP3-dependent NADH depletion [PDF]
, 2015 肿瘤坏死因子（tumornecrosisfactor，TNF）能诱导L929细胞产生相互作用蛋白3（receptor-interactingprotein3，RIP3）依赖的程序性细胞坏死，并且在该过程中，胞内的线粒体产生的活性氧（reactiveoxygenspecies，ROS）会积聚，同时当RIP3的表达水平敲低时，胞内ROS的积聚也受到了抑制。但是RIP3如何影响ROS的具体机制仍不清楚。 因为ROS的产生主要在线粒体电子传递链上，而还原型辅酶Ⅰ（NADH）和还原型辅酶Ⅱ（NADPH ...

Veterinary Dermatology, Volume 35, Issue 5, Page 524-535, October 2024.Background – Cytological detection of acantholytic keratinocytes (acantholytic cells [AC]) helps to identify canine pemphigus foliaceus (cPF) yet AC also occurs in superficial pyoderma (SP), the main differential diagnosis. Hypothesis/Objectives – To compare selected cytomorphological features of cPF and SP and to establish cytological diagnostic ...

细胞遗传学联合免疫细胞化学检查在首诊非霍奇金淋巴瘤骨髓侵犯中的应用
Zhongguo shiyan zhenduanxue, 2010 目的探讨细胞遗传学和免疫细胞化学检查在非霍奇金淋巴瘤骨髓侵犯（NHL-BMI）中的诊断价值。方法骨髓标本直接涂片Wright-Gimsa染色观察其形态学改变。应用骨髓细胞短期培养法制备染色体标本,以R显带技术进行核型分析。分离骨髓单个核细胞进行免疫细胞化学染色。结果24例淋巴瘤患者,骨髓受累程度各异,淋巴瘤细胞形态多样。CD20和CD79a对B细胞来源、CD3对T细胞来源淋巴瘤有诊断价值。有染色体核型异常的病例占54%（13/24）,2例骨髓轻度受累患者检出核型异常。结论综合细胞遗传学 ...
