癌胚抗原相关细胞黏附分子和人胸肾表达趋化因子在婴幼儿血管瘤组织中的表达

目的 检测癌胚抗原相关细胞黏附分子(CEACAM-1)和人胸肾表达趋化因子(CXCL-14)在不同时期婴幼儿血管瘤组织中的表达,并探讨其在血管瘤发生发展过程中的作用和意义.方法 应用免疫组化法和Western免疫印迹检测CEACAM-1和CXCL-14在增生期、消退期和消退完成期婴幼儿血管瘤组织中的表达,利用计算机图像分析技术测量平均吸光度.结果 CEACAM-1在增生期血管瘤组织中不表达或低表达,消退期呈强阳性表达,消退完成期呈阳性表达;各期之间CEACAM-1的表达差异有统计学意义(P<0.05);CXCL-14在增生早期血管瘤组织中不表达或低表达,消退期呈阳性表达,消退完成期呈强阳性表达,各期之间CXCL-14表达差异有统计学意义(P<0.05).结论 CEACAM-1和CXCL-14可能参与了婴幼儿血管瘤病理变化过程,在该病发生发展过程中起一定的作用.

The expression of CEACAM-1 and CXCL-14 in infantile hemangioma

Objective To examine the expression of CEACAM-1 and CXCL-14 in the different stages of infantile hemangioma and to explore the role of CEACAM-1 and CXCL-14 in the occurrence and development of infantile hemangioma. Methods The expression of CEACAM-1 and CXCL-14 was detected by immunohistochemical technique and Western Blot in cases of proliferating hemangiomas, involuting hemangiomas, involuted hemangiomas. The mean optical density was measured by image analysis system. Results The expression of CEACAM-1 in early stage of proliferating hemangiomas was weak or negative, while it was strong in involuting hemangiomas and positive in the involuted stage. The differences between different stages had a statistically significance (P <0. 05). The expression of CXCL-14 was weak or negative in stage of proliferating hemangiomas, positive in involuting hemangiomas and strong in the involuted stage. The differences between different stages had a statistically significance (P <0. 05). Conclusions CEACAM-1 and CXCL-14 are involved in the occurrence and development of infantile hemangioma.
