Congenital abdominal adhesions are a rare condition that can result in a small bowel obstruction at any age, more frequently in pediatric populations. The cause remains unknown, and the importance of aberrant congenital bands is related to the difficulty of diagnosis, and cases of death with late detection have been documented. This research examines the expression of Caudal Type Homeobox 1 (CDX1), Indian Hedgehog (IHH), Sonic Hedgehog (SHH), GATA Binding Protein 4 (GATA4), Forkhead Box A2 (FOXA2) and Forkhead Box F1 (FOXF1) gene expression in human abdominal congenital adhesion fibroblast and endothelium cells by chromogenic in situ hybridization, with the aim of elucidating their potential association with the etiology of congenital intra-abdominal adhesion band development. The potential genes' signals were examined using a semi-quantitative approach. Significant correlations were observed between the expression of CDX1 ( <.001) and SHH (=0.032) genes in fibroblasts from congenital intra-abdominal adhesions compared to fibroblasts from control peritoneal tissue. Statistically significant very strong correlations were found between the CDX1 and IHH comparing endothelium and fibroblast cells in congenital abdominal adhesion bands. There was no statistically significant difference found in the distribution of IHH, FOXA2, GATA4, and FOXF1 between the fibroblasts and endothelium of the patients compared to the control group. The presence of notable distinctions and diverse associations suggests the potential involvement of numerous morpho-pathogenetic processes in the development of intraabdominal adhesions.
先天性腹部粘连是一种罕见的病症,可在任何年龄导致小肠梗阻,在儿科人群中更为常见。其病因尚不清楚,异常先天性束带的重要性与诊断困难有关,并且已有晚期检测导致死亡的病例记录。本研究通过显色原位杂交检测尾型同源盒1(CDX1)、印度刺猬蛋白(IHH)、音猬因子(SHH)、GATA结合蛋白4(GATA4)、叉头框A2(FOXA2)和叉头框F1(FOXF1)基因在人腹部先天性粘连成纤维细胞和内皮细胞中的表达,旨在阐明它们与先天性腹腔内粘连带形成病因的潜在关联。使用半定量方法检测潜在基因的信号。与对照腹膜组织的成纤维细胞相比,先天性腹腔内粘连成纤维细胞中CDX1(<.001)和SHH(=0.032)基因的表达之间观察到显著相关性。在先天性腹部粘连带的内皮细胞和成纤维细胞中,CDX1和IHH之间存在统计学上显著的强相关性。与对照组相比,患者的成纤维细胞和内皮细胞中IHH、FOXA2、GATA4和FOXF1的分布没有统计学上的显著差异。显著差异和不同关联的存在表明多种形态发生病理过程可能参与了腹腔内粘连的形成。
