目的 研究EphB2在先天性肛门直肠畸形直肠末端组织中的表达并探讨其临床价值.方法 采用免疫组织化学法和免疫荧光分析方法检测20例先天性肛门直肠畸形患儿直肠末端肠壁和8例正常对照直肠末端肠肇的EphB2的表达情况.结果 免疫组织化学检测到EphB2蛋白在畸形组和对照组均有表达,定位在直肠肠壁黏膜层细胞的胞质和胞膜中.畸形组EphB2表达的累积光密度值(30.43±11.41)明显低于对照组(81.62±20.45),差异有统计学意义(P<0.01).结论 EphB2在肛门直肠畸形的直肠末端黏膜层表达水平减低,EphB2的表达可能和先天性肛门直肠畸形的发生密切相关.
Expression and valuation of EphB2 in human anorectal malformation
Objective The aim of this study is to evaluate the expression of EphB2 protein in terminal rectum with congenital anorectal malformation(CAM) and to assess its clinical significance. Methods Specimens were obtained from 20 patients with CAM, and 8 normal controls. Expression of EphB2 was determined by SP immunohistochemistry and immunofluorescence. Results The expression of EphB2 was mainly located in the cytoplasm and cell membrane of the mucous layer by immunohistochemistry. The positive expression intensity of EphB2 proteins were significantly lower in the malformation group (30.43 ± 11.41) than in the control group (81.62 ± 20.45) by integrated optical density(IOD) (P<0.01). Conclusions There was decreased expression of EphB2 in the mucous layer of CAM. Results suggested that EphB2
