0.05). All of the indexes in control group were lower on post-operative day 7 than those of pre-operation. The levels of pre-albumin,transferrin, fibronectin, IgG,IgM, CD~+_3, CD~+_4 T cells and nitrogen balance in the study group were significantly higher than those of control group.Negative nitrogen balance began to be positive in the study group on the post-operative day 7. However, the nitrogen balance in the control group was still negative on the post-operative day 10. The duration of hospitalization in the r-hGH group was shorter than that of the control group. The 1-year, 2-year and 3-year survival rates and recurrence rate were not different between two groups.(Conclusions) The post-operative short-term use of the r-hGH plus HPN in patients with excisable gastrointestinal cancer is safe, effective and benefit for the post-operative recovery.
