摘要 目的探讨细胞因子中转化生长因子(TGF)在鼻息肉组织中的表达,以及全身应用糖皮质激素对TGF水平的影响。方法治疗组:术前应用糖皮质激素全身治疗1周,糖皮质激素治疗剂量为10mg,静脉滴注,每日1次。对照组:术前未应用任何药物。术后取鼻息肉组织经采用免疫组化SP法,检测在糖皮质激素治疗前后TGF在鼻息肉组织中的表达。运用HPIA2000高分辨率图像分析系统分别对糖皮质激素治疗前后鼻息肉组织的黏膜上皮细胞、腺上皮细胞、血管内皮细胞、间皮浸润炎性细胞进行光密度测定分析。结果激素治疗后TGF在鼻息肉各组织中阳性表达的光密度值均小于治疗前(P<0.05)。结论应用糖皮质激素可以降低鼻息肉组织中TGF在上皮细胞、淋巴细胞中的表达,抑制黏膜上皮增生,减弱血管生成作用,减轻嗜酸粒细胞在鼻息肉组织中的浸润,抑制鼻息肉的形成。
