ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the effect of early enteral nutrition(EEN) on immune response and clinical outcomes after esophageal cancer operation.</p><p><b>METHODS</b>Sixty patients with esophageal cancer undergoing radical operation between March 2010 and July 2011 were randomly divided into two groups using envelope method: EEN group(n=30, administration of water and enteral nutrition early after operation) and TPN group(n=30, administration of total parenteral nutrition). Two groups both received 7-day nutrition support. Immune indexes(CD3(+), CD4(+), CD8(+), CD4(+)/CD8(+)) and serum nutritional indexes(albumin, pre-albumin, transferrin) were measured before operation and 1-, 3-, and 7-day after operation. The time to first flatus, length of postoperative hospital stay, total hospitalization cost, and postoperative complication were recorded.</p><p><b>RESULTS</b>As compared to TPN group, the time to first flatus was significantly shorter in EEN group[(66.5±7.3) h vs. (75.1±6.8) h, P<0.01], as was hospital stay[(7.8±1.1) d vs. (9.3±1.3) d, P<0.01]. Total hospitalization cost[(36 210±3810) yuan vs. (39 731±4013) yuan, P<0.01] was lower in EEN group as compared to TPN group. There was no significant difference in postoperative complication rate between the two groups[13.3%(3/30) vs. 20.0%(6/30), P>0.05]. The levels of CD3(+), CD4(+), CD4(+)/CD8(+), albumin, prealbumin and transferrin were significantly higher in EEN group as compared to TPN group on postoperative day 3 and 7(all P<0.05), while CD8(+) was significantly lower in EEN group(P<0.05).</p><p><b>CONCLUSION</b>EEN can promote early recovery of gastrointestinal function, improve nutritional and immune function, and therefore lead to fast postoperative recovery in esophageal cancer patients.</p>

Objective To determine the length of warm ischemic (WI) tolerance in bronchial graft from non-heart-beating donors. Methods Forty-eight rats were randomly divided into 4 groups (each group having 12 rats) according to different WI durations including WI-0 min (group A), WI-30 min (group B), WI-45 min (group C) and WI-60 min (group D). In each group, the tracheae from 6 rats were respectively imbedded in greater omentum of other 6 rats, and 14 days later, the transplanted tracheae were taken from recipients to evaluate epithelial thickness and regeneration. Results Epithelial thickness and the degree of epithelial regeneration had no significant difference (P >0. 05) between the syngeneic control group and the WI-30 minutes group. All of the grafts with WI duration of 45 min were viable, but the epithelium was significantly thinner than that in the syngeneic control group (P<0. 05). However all of the grafts with WI duration of 60 min showed lower viability rate. Conclusion The time limits of tolerance to WI of tracheal grafts from NHBDs may be 45 min.
