Objective To investigate the influence of early oral feeding (EOF)after laparoscopic surgery in the function status and gastrointestinal living quality of the patients with colorectal cancer,and to clarify the feasibility of EOF after laparoscopic surgery.Methods Sixty-three patients underwent laparoscopic surgery of colorectal cancers participated in the trial.Of these,31 patients received EOF as EOF group,received a clear liquid diet on the first postoperative day followed by a regular diet as tolerated;the other 32 patients received traditional oral feeding (TOF ) as TOF group who were fed with feeding only after the recovery of their postoperative gastrointestinal functions. The nasogastric tube was removed from all patients in both groups immediately after surgery.Self-designed EOF questionnaire data, Karnofsky Scores and Gastrointestinal Quality of Life Index (GIQLI)Scores were used to evaluate the functional status and gastrointestinal living guality of the patients. Results The using time of total parenteral nutrition (TPN),time of postoperative hospital stay,and costs after surgery in EOF group were lower than those in TOF group (P<0.05);but there were no significnat differences in the first passage of flatus and feces time between two groups (P<0.05),also there were no significant differences in the incidence of nasogastric tube reinsertion, pulmonary infection, intestinal obstruction, balance of intestinal bacteria,fistula,incision infection between two groups (P>0.05),and the incidence of abdominal distension was higher than that in TOF group (P<0.05);on postoperative day 7,the albumin recovered faster in EOF group (P<0.05),and on postoperative day 4 and 7,the pro-albumin also recovered faster in EOF group (P<0.05);the patients in EOF group had a higher Karnofsky score (P<0.05)and GIQLI score compared with the patients in TOF group (P<0.05 ). Conclusion EOF after laparoscopic surgery in the patients with colorectal cancers is beneficial for rehabilitation,and it can reduce the risk of hospitalization and saving its costs;it plays an active role in protein recovery,and improves the functional status and gastrointestinal living quality of the patients.

BACKGROUND: Islet transplantation is an effective therapy for type I diabetic patients sensitive to insulin.OBJECTIVE: To investigate and evaluate the status and obstacles of islet transplantation in type I diabetes in China.METHODS: Published articles reported from January 1980 to December 2008 on Chinese Medical Current Contents database,the national funds from 2002 to 2008 in the database of National Natural Science Foundation of China on islet transplantation were searched to analyze the status of islet transplant research and clinical practice in China.RESULTS AND CONCLUSION: 340 articles were reported from 1980 to 2008 related to islet transplantation in China, including 165 (48.5%) basic research, 45 (13.2%) clinical research and 130 (38.2%) reviews. Most of researches were conducted in the developed regions in the east of China. The Edmonton protocol had a great impact on the islet transplant research in China, and many projects of islet transplant have been supported by the National Natural Science Foundation. However, there remains obstacles in this field, such as organ and capital shortage and incomplete organ donation system.
