Abstract:
Objective To investigate the expression of immunohistochemistry of gastrin(GAS),somatostatin(SS),proliferating cell nuclear antigen(PCNA) and Fas-ligand(Fas-L) in the sinus ventriculi of children with pediatric gastritis and to explore the significance of their expression in the pathogenesis of pediatric chronic gastritis.Methods Fifty cases of the sinus ventriculi mucosa samples were enrolled in 3 groups:chronic gastritis,helicobacter pylori(Hp) positive(group A,n=20);chronic gastritis,Hp negative(group B,n=19);control group,normal sinus ventriculi mucosa,Hp negative(group C,n=11).Immunohistochemistry En Vision were carried out including GAS,SS,PCNA and Fas-L.Results In the expression of GAS and SS,the values of group A and B were comparatively higher than those of group C,but there was no significant difference among them in statistics.In the expression of PCNA,the value of group A was comparatively higher and that of group B.The value difference between 2 groups was significant(P=0.019);in the expression of Fas-L,no significant difference was found among these 3 groups.Conclusions Expressions of GAS and SS both increase in children with chronic gastritis and maybe the increase of GAS and SS play a role in the pathogenesis of pediatric chronic gastritis;Hp infection promotes the multiplication of the sinus ventriculi membrana mucosa epithelium cell in pediatric chronic gastritis.
