Abstract

The inflammatory response is closely associated with sepsis occurrence and progression. Damage to the function of the intestinal mucosal barrier is considered to be the ῾initiation factor᾿ for the development of multiple organ dysfunction syndrome, which is the most severe progression of sepsis. The aim of the present study was to investigate whether gadolinium chloride (GdCl3) could alleviate the systemic inflammatory response and protect the function of the intestinal mucosal barrier in a rat model of sepsis. The mechanism underlying this protective effect was also explored. Sprague‑Dawley rats were divided into four groups: Sham, sham + GdCl3, cecal ligation and puncture (CLP; a model of sepsis) and CLP + GdCl3. In each group, blood was collected from the abdominal aorta, and intestinal tissue was collected after 6, 12 and 24 h of successful modeling. Levels of tumor necrosis factor‑α, interleukin (IL)‑6 and IL‑1β were determined using ELISA. Western blot analysis was used to determine levels of occludin, tight junction protein ZO‑1 (ZO‑1), myosin light chain kinase 3 (MLCK), NF‑κB and caspase‑3 in intestinal tissues. Hematoxylin‑eosin staining was used to observe the degree of damage to intestinal tissue. The results indicated that in CLP sepsis model rats treated with GdCl3, the release of systemic and intestinal pro‑inflammatory factors was reduced and tissue damage was alleviated when compared with untreated CLP rats. Additionally, the expression of occludin and ZO‑1 was increased, while that of NF‑κB, MLCK, and caspase‑3 was reduced in the CLP + GdCl3 rats compared with the CLP rats. GdCl3 may alleviate systemic and intestinal inflammatory responses and reduce the expression of MLCK through inhibition of the activation of NF‑kB. The results of the present study also indicated that GdCl3 promoted the expression of occludin and ZO‑1. GdCl3 was also demonstrated to reduce cell apoptosis through the inhibition of caspase‑3 expression.
