Abstract: Objective: To explore the expressions of interleukin-17E(IL-17E),interleukin -17F(IL-17F) and their receptors interleukin -17RB(IL-17RB),interleukin -17RC(IL-17RC) in enteritis,intestinal polyps and colorectal carcinoma tissues,and to analyze their relationships with the malignancy of colorectal carcinoma. Methods: Immunohistochemistry staining was used to detect the expressions of IL-17E,IL-17RB,IL-17F, and IL-17RC in the tissues of enteritis (n=15),intestinal polyps (n=5) and colorectal carcinoma (n=30).The relationships between IL-17E and IL-17RB,IL-17F and IL-17RC,and the relationships between IL-17E,IL-17F and malignancy of colorectal carcinoma were analyzed. Results: IL-17E,IL-17F,IL-17RB and IL-17RC mainly expressed in glandular epithelial cells,mononuclear cells and vascular endothelial cells as well as partial carcinoma cells.The positive expression rates of IL-17E in enteritis and intestinal polyps tissues were higher than that in colorectal carcinoma tissue (P<0.05).Compared with enteritis tissue,the positive expression rates of IL-17F in intestinal polyps and colorectal carcinoma tissues were increased (P<0.05),which was increased with the increasing of malignancy of coloretal carcinoma.Compared with colorectal carcinoma tissue,the positive expression rates of IL-17RB in enteritis and intestinal polyps tissues were increased (P<0.05).Compared with enteritis and intestinal polyps tissues,the positive expression rate of IL-17RC in colorectal carcinoma tissue was increased (P<0.05).There was positive correlation between the positive expression rate of IL-17F and the positive expression rate of IL-17RC in colorectal carcinoma tissue(r=0.667,P=0.001). Conclusion: IL-17F,IL-17RC,IL-17E,and IL-17RB signals may take part in the incidence and progression of colorectal carcinoma.

Key words: colonrectal neoplasms, interleukin-17E, interleukin -17RC, interleukin -17RB, interleukin -17F
