ObjectiveTo observe the effect of succus entericus reinfusion with continuous enteral nutrition on the barrier function of intestinal mucosa and nutritional status in patients with stomal type fistulas. Methods Sixteen patients with stomal type fistula from July 1995 to May 2008 were enrolled in the study. A]l patients met the following conditions: gut function returned normal; abdominal infection was controlled; total enteral nutrition was provided ; and the length of small intestine for succus entericus reinfusion was more than 50 cm. Intestinal mucosa was taken at 25 to 30 cm away from stoma of fistula by endoscope 0, 7, and 14 days after reinfusior. Hematoxylineosin staining was performed to count the number of intestinal intraepithelial lymphocytes (IIELS). In addition,proliferating cell nuclear antigen (PCNA) was measured with immunohistochemical staining. Serum protein levels were determined by immunonephelometry. ResultsThe percentage of IIELS in intestinal mucosa ( 19.06％ ±4.81％ vs. 12.81％ ±2.95％, P=0.000) and the percentage of PCNA positive cells ( 12.13％ ±4.33％ vs.6.44％ ± 2.34％, P =0.000) 14 days after succus entericus reinfusion were significantly higher than those on the day of reinfusion. Serum fibronectin level increased from ( 152.80 ± 16.50 ) to ( 227.05 ± 45.36 ) mg/L ( P =0.000), and transferring protein level increased from ( 2.16 ± 0.52 ) to ( 2.62 ± 0.41 ) g/L ( P =0.017 ) 14days after succus entericus reinfusion. ConclusionSuccus entericus reinfusion is effective in protecting the intestinal mucosa in patients with stomal type fistulas.

Clinical data of 14 patients with iatrogenic duodenal injuries treated in hospital from January 2000 and January 2010 were retrospectively reviewed.Iatrogenic duodenal injuries were found intraoperatively in 9 cases,in whom repair or additional jejunostomy was performed and all were cured and discharged.In 2 patients the duodenal injuries were found within 24 hours postoperatively,1 was cured,another had low flow duodenal fistula and cured with conservative treatment.Duodenal bypass and extraoral drainage were performed in 2 patients whose duodenal injuries was found 72 hours after surgery and died from severe infection of retroperitoneal space and multiple organ failure respectively.One patient whose duodenal injury was found 7 d postoperatively suffered from septic shock and died in 4 h after admission.The results suggest that early detection and early management would result in satisfied outcome for patients with iatrogenic duodenal injuries,the first 24 hours are crucial.

The development of clinical pathways must "start and end up with education" as put by the authors. The article discussed the objectives, significance and contents, as well as approaches in the education of clinical pathways. It recommended a tiered education for hospital leaders, medical care workers, office staff, patients and their family members, and different target groups and contents in the education for clinical pathways application.

Objective Studies on the changes of gastrin and SS immunoreactive cells in pancreatic islets during experimental gastric ulcer. Methods The immunohistochemical ABC technique was used. Results The gastrin immunoreactive cells were located in most of the pancreatic islet. The mumber of G cells in experimental gastric ulcer group were higher than that of control group on the 4th and 10th day after operation.The D cells raised on the 10th day.Conclusion The present work provides the evidence that the G and D cells of pancreatic islets might be involed in the self-healing process of the experimental gastric ulcer by endocrine or paracrine regulation.
