RESUMO
Objective To elucidate the effect of postoperative early enteral nutrition support (ENS) on cellular immunity function and nutritional status of gastrointestinal (GI) cancer patients.Methods Twenty patients with GI cancer were at random divided into two groups: enteral nutrition group (EN-group, 10 cases), parental nutrition group (PN-group, 10 cases). PN-group was given total parental nutrition (TPN).In EN-group,Since the 1st postoperative day Neutrinos(r) was infused, the infused volume was increasingly added from 500 ml/d to 1 500 ml/d, the infused rate was step-by-step increased from 21 ml/h to 63ml/h. T-cell subgroup, NK cell, IL-2, PA, RBP were measured in the day before operation and on the 2nd ?4th ?8th postoperative day.Results ① The serum RBP,PA levels were obviously decreased postoperatively (P
