Background: Inflammation is supposed to play a key role in the pathophysiological processes of intestinal ischemia-reperlhsion injury (IIRI), and Candida albicans in human gut commonly elevates inflammatory cytokines in intestinal mucosa. This study aimed to explore the effect of C. albicans on IIRI. Methods: Fifty female Wistar rats were divided into five groups according to the status of C. a/bicans infection and IIRI operation: group blank and sham; group blank and IIRI; group cetbperazone plus IIR1; group C. albicans plus cetbperazone and IIRI (CCI); and group C. albicans plus cefbperazone and sham. The levels of inflammatory factors tumor necrosis factor (TNF)-a, interleukin (IL)-6, IL- 1 β, and diamine oxidase (DAO) measured by enzyme-linked immunosorbent assay were used to evaluate the inflammation reactivity as well as the integrity of small intestine. Histological scores were used to assess the mucosal damage, and the C. albicans blood translocation was detected to judge the permeability of intestinal mucosal barrier. Results: The levels of inflammatory factors TNF-a, IL-6, and IL-1β in serum and intestine were higher in rats undergone both C. albicans infection and IIRI operation compared with rats in other groups. The levels of DAO (serum: 44.13 ± 4.30 pg/ml, intestine: 346.21 ± 37.03 pg/g) and Chiu scores (3.41 ± 1.09) which reflected intestinal mucosal disruption were highest in group CCI after the operation. The number ofC. albicans translocated into blood was most in group CCI ([33.80 ± 6.60] x 10-2 colony forming unit (CFU)/ml). Conclusion: Intestinal C. albicans infection worsened the llRl-induced disruption of intestinal mucosal barrier and facilitated the subsequent C. alhicans translocation and dissemination. 展开更多
