摘要 ①目的观察血管内皮生长因子受体3在慢性鼻-鼻窦炎病变黏膜及伴发鼻息肉中的表达强度、表达部位是否存在差异,探讨其在疾病形成中可能的作用。②方法选择诊断明确的慢性鼻-鼻窦炎1型患者(慢性鼻窦炎组,A组)15例,慢性鼻窦炎2型和3型患者(鼻息肉组,B组)15例作为观察组,分别留取窦口鼻道复合体处的肥厚黏膜或息肉组织,进行HE染色及免疫组化染色。选择同期因鼻中隔偏曲入院的患者11例,留取下鼻甲黏膜作为对照组(C组)。光学显微镜下观察阳性细胞表达强度和表达位置有无差异。③结果 VEG-FR-3在上皮部位的表达程度,观察组与对照组之间不同,其中B组与对照组之间的表达差异有统计学意义(P<0.05)。VEGFR-3在腺体部位的表达程度,观察组与对照组之间不同,其中A组与对照组之间的表达差异有统计学意义(P<0.05)。VEGFR-3在血管部位的表达程度,观察组与对照组之间不同,其中B组与对照组之间的表达差异有统计学意义(P<0.05)。④结论 VEGFR-3在慢性鼻窦炎病变黏膜及伴发息肉中存在高表达,表达位置和表达强度不同;VEGFR-3在2型和3型慢性鼻窦炎形成过程中,可能存在促进上皮增生和鳞化,增加小血管数量的作用,从而促进息肉形成。
