  • Expressions and clinical significance of SDF-1 and CXCR4 in local tissues of perianal abscess

    ObjectiveTo investigate the expressions of stromal cell-derived factor-1 (SDF-1) and chemokine receptor-4 (CXCR4) in local tissues of perianal abscess and their relationships with clinicopathological features and prognosis of patients.MethodsA total of 47 patients with perianal abscess (perianal abscess group) and 58 patients with mixed hemorrhoids (mixed hemorrhoids group) were selected for the study. The tissues were collected during the operation. Real-time quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to detect the expressions of SDF-1 mRNA and CXCR4 mRNA in local tissues of the two groups, the positive expressions of SDF-1 protein and CXCR4 protein in local tissues were detected by immunohistochemistry, and the relationships between the expressions of SDF-1 and CXCR4 protein and the clinical characteristics, prognosis of patients were analyzed.ResultsThe expression levels of SDF-1 mRNA and CXCR4 mRNA in the perianal abscess group were higher than those in the mixed hemorrhoids group, and the positive rates of SDF-1 protein and CXCR4 protein in the perianal abscess group were higher than those in the mixed hemorrhoids group too (P<0.05). The expressions of SDF-1 protein and CXCR4 protein in perianal abscess tissues were both not related to sex, age, location of abscess, and course of disease (P>0.05), but was related to abscess diameter, healing time, and anal fistula (P<0.05). The non-recurrence rates of SDF-1 protein-negative group and CXCR4 protein-negative group were lower than those of SDF-1 protein-positive group and CXCR4 protein-positive group respectively (P<0.05).ConclusionSDF-1 and CXCR4 molecular are up-regulated in the local tissues of perianal abscess, which are related to the size of abscess, healing time, anal fistula, and recurrence of patients.
