Methods: Fifty SD healthy male rats were randomly divided into 5 groups ( n = 10 per group) : Group A ( Sham group), Group B ( Ringer' s solution for 1 h ), Group C (Ringer' s solution for 24 h ), Group D ( hydroxyethyl starch for 1 h ) and Group E (( hydroxyethyl starch for 24 h). A model of rats with hemorrhagic shock was established. The bacterial translocation in liver, content of tumor necrosis factor-α (TNF-α) and changes of myeloperoxidase enzyme (MPO) activities in small intestine were pathologically investigated after these two fluid resuscitations, respectively. Results : The bacterial translocation and the expression of TNF-α in the small intestine were detected at 1 h and 24 h after fluid resuscitation. There were significant increase in the number of translocated bacteria, TNF-α and MPO activities in Group C compared with Group B, significant decrease in Group E compared with Group D and in Group B compared with Group D. The number of translocated bacteria and TNF-α expression significantly decreased in Group E as compared with Group C. Conclusions: The bacterial translocation and the expression of TNF-α in the small intestine exist 24 h after fluid resuscitation. 6 % hydroxyethyl starch can improve the intestinal mucosa barrier function better than the Ringer' s solution.展开更多
