| 1 | Controlling postoperative ileus by vagal activation显示文摘Postoperative ileus is a frequently occurring surgical complication, leading to increased morbidity and hospital stay. Abdominal surgical interventions are known to result in a protracted cessation of bowel movement. Activation of inhibitory neural pathways by nociceptive stimuli leads to an inhibition of propulsive activity, which resolves shortly after closure of the abdomen. The subsequent formation of an inflammatory infiltrate in the muscular layers of the intestine results in a more prolonged phase of ileus. Over the last decade, clinical strategies focusing on reduction of surgical stress and promoting postoperative recovery have improved the course of postoperative ileus. Additionally, recent experimental evidence implicated antiinflammatory interventions, such as vagal stimulation, as potential targets to treat postoperative ileus and reduce the period of intestinal hypomotility. Activation of nicotinic receptors on inflammatory cells by vagal input attenuates inflammation and promotes gastrointestinal motility in experimental models of ileus. A novel physiologicalintervention to activate this neuroimmune pathway is enteral administration of lipid-rich nutrition. Perioperative administration of lipid-rich nutrition reduced manipulation-induced local inflammation of the intestine and accelerated recovery of bowel movement. The application of safe and easy to use antiinflammatory interventions, together with the current multimodal approach, could reduce postoperative ileus to an absolute minimum and shorten hospital stay. | Tim Lubbers Wim Buurman Misha Luyer | 2010 | World Journal of Gastroenterology2010，16，14： | 10 |
| 2 | Hemolysis results in impaired intestinal microcirculation and intestinal epithelial cell injury显示文摘AIM:To study the effect of circulating cell-free oxy-hemoglobin(FHb) on intestinal microcirculation and intestinal epithelial injury in a rat model. METHODS:To induce elevated intravascular circulating FHb,male Sprague-Dawley rats received water or FHb infusion.Microcirculatory changes in jejunum,ileum and colon were evaluated using fluorescent microspheres.Intestinal injury was quantified as plasmatic release of ileal lipid binding protein(iLBP) and verified by histological analysis of the ileum. RESULTS:Water and FHb infusions resulted,when compared with saline infusion,in reduced intestinal microcirculation(after 30 min P<0.05,or better;after 60 min FHb infusion P<0.05 for jejunum and colon) .Circulating FHb levels correlated significantly with release of iLBP(Spearman r=0.72,P=0.0011) .Epithelial cell injury of the villi was histologically observed after water and FHb infusions. CONCLUSION:This study shows that circulating FHb leads to a reduction in intestinal microcirculatory blood flow with marked injury to intestinal epithelial cells. These data support the hypothesis that circulating FHb contributes to the development of intestinal injury. | Sebastiaan J Hanssen Tim Lubbers Caroline M Hodin Frits W Prinzen Wim A Buurman Michael J Jacobs | 2011 | World Journal of Gastroenterology2011，17，2： | 0 |
