Of them, 9 were from BLOM with dysplasia, 15 from BLOM without dysplasia,15 from oral squamous cell carcinoma (OSCC), 15 from oral precancerosis, and 10 from normal tissues. Cell proliferation, apoptosis and angiogenesis of tissue samples were also analyzed.RESULTS: The expression of Ki-67 in BLOM with dysplasia,oral precancerosis and OSCC was significantly higher than in BLOM without dysplasia and normal mucosa. The microvascular density (MVD) in BLOM with and without dysplasia, oral precancerosis, and OSCC was significantly higher than in normal mucosa. Apoptosis in BLOM and oral precancerosis was significantly higher than in OSCC and normal mucosa.CONCLUSION: Benign lymphoadenosis of oral mucosa has potentialities of cancerization.展开更多

目的:探讨CD44与CD33在口腔黏膜良性淋巴组织增生病(benign lymphoadenosis of oral mucosa,BLOM)中的表达及临床意义。方法:选择2017年1月—2020年3月青岛市中医医院病理科77例BLOM蜡块作为实验组,另取同时间段63例正常口腔黏膜组织蜡...目的:探讨CD44与CD33在口腔黏膜良性淋巴组织增生病(benign lymphoadenosis of oral mucosa,BLOM)中的表达及临床意义。方法:选择2017年1月—2020年3月青岛市中医医院病理科77例BLOM蜡块作为实验组,另取同时间段63例正常口腔黏膜组织蜡块作为对照组。采用免疫组织化学法检测2组CD44、CD33阳性表达情况,采用Spearman分析BLOM患者病变组织中CD33与CD44阳性表达的相关性。收集患者一般资料,分析BLOM患者病变组织中CD33、CD44表达与临床病理特征的关系。采用SPSS 21.0软件包对数据进行统计学分析。结果:对照组、实验组CD33阳性表达率分别为95.24%、63.64%,差异有统计学意义(P<0.05);CD44阳性表达率分别为93.65%、67.53%,差异有统计学意义(P<0.05)。Spearman分析结果显示,BLOM患者病变组织中CD33与CD44阳性表达呈正相关(r=0.834,P=0.002);CD33、CD44表达与临床分型、炎症程度、有无淋巴滤泡、淋巴细胞浸润有关(P<0.05),而与年龄、性别、病程、病变部位、上皮表面角化无关(P>0.05)。结论:BLOM患者病变组织中CD33、CD44阳性表达率下降,与临床分型、炎症程度、有无淋巴滤泡、淋巴细胞浸润密切相关。展开更多
