PG - 4903-12 AB - Intestinal injury is a key feature in sepsis. Heparanase, a heparin sulfate-specific glucuronidase, mediates the onset of organ injury during early sepsis. Heparin has the function to attenuate inflammation and injury induced by multiple factors; however, whether unfractionated heparin (UFH) can attenuate the intestinal injury induced by sepsis as well as the underlying mechanism is still unknown. In the present study, the function of UFH in intestinal injury induced by sepsis was explored. Results of our study showed that after CLP operation, the inflammatory response and expression of heparanase were increased and NF-kappaB and MAPK P38 signaling pathways were activated. However, pretreatment with UFH will inhibit the expression and activation of heparanase, and reverse the activation of NF-kappaB and MAPK P38 signaling pathways, thus attenuating inflammatory responses induced by sepsis. These results suggest that UFH may be a promising therapeutic drug for intestinal injury caused by sepsis.
