目的:检测常见泪腺上皮性肿瘤中类表皮生长因子结构域7(EGFL7)、微血管密度(MVD)、Ki67的表达,探究EGFL7与MVD、Ki67之间的相互关系。方法:应用免疫组化法,对10例正常泪腺组织(取自因炎性假瘤、Mikulicz病等良性泪腺肿瘤切除后,标本中... 目的:检测常见泪腺上皮性肿瘤中类表皮生长因子结构域7(EGFL7)、微血管密度(MVD)、Ki67的表达,探究EGFL7与MVD、Ki67之间的相互关系。方法:应用免疫组化法,对10例正常泪腺组织(取自因炎性假瘤、Mikulicz病等良性泪腺肿瘤切除后,标本中的部分正常泪腺组织)、20例泪腺多形性腺瘤、12例多形性腺癌、14例腺样囊性癌组织中的EGFL7蛋白、Ki67进行检测,并应用CD34标记计数MVD。结果:EGFL7主要在泪腺多形性腺癌、腺样囊性癌的肿瘤细胞的细胞浆中表达,免疫组化染色结果显示,在正常泪腺组织中EGFL7无阳性表达,泪腺多形性腺瘤组织中EGFL7的阳性率为5%(1/20),泪腺多形性腺癌中EGFL7的阳性表达率83%(10/12),泪腺腺样囊性癌中EGFL7的阳性表达率为86%(12/14),两种恶性肿瘤中的表达率明显高于多形性腺瘤和正常泪腺组织(P<0.001)。CD34可使肿瘤微血管染色呈棕黄色的单个或成簇细胞群。在泪腺多形性腺癌(32.58±14.46)及腺样囊性癌(43.43±4.60)中CD34的表达明显高于多形性腺瘤(4.20±1.19)(P<0.001);Ki67在具有增殖活性的细胞核呈棕褐色着色,在泪腺多形性腺癌(44.83±13.68)及腺样囊性癌(26.29±8.44)中Ki67的表达明显高于多形性腺瘤(2.80±3.14)及正常组织(0.40±0.70)(P<0.001)。在两种恶性肿瘤中EGFL7的表达分别与MVD、Ki67呈明显正相关(rs=0.897,P<0.001;rs=0.837,P<0.001)。结论:EGFL7在泪腺上皮性肿瘤中的表达与MVD、Ki67呈正相关性,提示EGFL7不仅在泪腺上皮性肿瘤血管生成中起重要作用,而且参与泪腺上皮性肿瘤的增殖。 展开更多

Objective:Renal fibrosis is the most common manifestation of chronic kidney disease(CKD).Noting that existing treatments of renal fibrosis only slow disease progression but do not cure it,there is an urgent need to identify novel therapies.Hydrogen sulfide(H2S)is a newly discovered endogenous small gas signaling molecule exerting a wide range of biologic actions in our body.This review illustrates recent experimental findings on the mechanisms underlying the therapeutic effects of H2S against renal fibrosis and highlights its potential in future clinical application.Data sources:Literature was collected from PubMed until February 2019,using the search terms including"Hydrogen sulfide,""Chronic kidney disease"MRenal interstitial fibrosis,"Kidney disease,""Inflammation factor,""Oxidative stress,""Epithelialto-mesenchymal transition,""H2S donor,""Hypertensive kidney dysfunction,""Myofibroblasts,""Vascular remodeling,""transforming growth factor(TGF)-beta/Smads signaling,"and"Sulfate potassium channels."Study selection:Literature was mainly derived from English articles or articles that could be obtained with English abstracts.Article type was not limited.References were also identified from the bibliographies of identified articles and the authors5 files.Results:The experimental data confirmed that H2S is widely involved in various renal pathologies by suppressing inflammation and oxidative stress,inhibiting the activation of fibrosis-related cells and their cytokine expression,ameliorating vascular remodeling and high blood pressure,stimulating tubular cell regeneration,as well as reducing apoptosis,autophagy,and hypertrophy.Therefore,H2S represents an alternative or additional therapeutic approach for renal fibrosis.Conclusions:We postulate that H2S may delay the occurrence and progress of renal fibrosis,thus protecting renal function.Further experiments are required to explore the precise role of H2S in renal fibrosis and its application in clinical treatment. 展开更多
