Objective To determine the trend in the causes of admission among diabetic patients in West China Hospital from 1996 to 2005. Methods The medical records of diabetic inpatients from January 1996 to December 2005 were retrieved, and half of them were randomly selected. A questionnaire was completed and SPSS13.0 software was used for statistical analyses. Results The most common causes of admission for diabetic patients were diabetic chronic complications (20.2%), infection (19.5%), hyperglycemic symptoms (11.7%), malignant tumor (8.9%) and diabetic acute complications (5.8%). The constituent ratios of diabetic macrovascular disease and malignant tumor as the admission causes tended to increase, while the constituent ratios of diabetic microvascular disease, hyperglycemic symptoms and diabetic acute complications tended to decrease. Infection remained as one of the main causes of admission among diabetic patients. Conclusion The main cause of admission to West China Hospital for diabetic patients from 1996 to 2005 was diabetic chronic complications.
Objective To investigate the effect of mesenteric lymphatic duct liagtion and glutamine enteral nutrition on intestine and distant organs in intestinal ischemia/reperfusion injury. Methods Forty male SD rats undergoing gastrostomy were randomly assigned into 5 groups (n=8): sham operation group, normal enteral nutrition group, normal enteral nutrition+lymphatic duct ligation group, glutamine group and glutamine+lymphatic duct ligation group. Sham operation group only received laparotomy after 7 days of full diet, the other four groups were subjected to 60 min of intestinal ischemia after 7 days of enteral nutrition, and the two lymphatic duct ligation groups were plus mesenteric lymphatic duct ligation. The original nutrition continued 3 days after reperfusion. Intestinal permeability was detected on day 1 before reperfusion, day 1 and 3 after reperfusion. Intestinal morphology was observed, endotoxin, D-lactate and diamine oxidase levels in serum, and apoptotic index in lung tissue were detected on day 3 after reperfusion. Results The intestinal permeability in each group was significantly increased on day 1 after reperfusion (Plt;0.05), and which in normal enteral nutrition+lymphatic duct ligation group and glutamine+lymphatic duct ligation group were significantly decreased on day 3 after reperfusion (Plt;0.05). The mucosal thickness and villus height of ileum and mucosal thickness of jejunium in glutamine+lymphatic duct ligation group were significantly higher than those in other groups (Plt;0.05), and villus height of ileum in glutamine group was higher than that in normal enteral nutrition group (Plt;0.05); those morphology indexes in normal enteral nutrition+lymphatic duct ligation group were higher than those in normal enteral nutrition group, but there was no statistical signification (Pgt;0.05). Apoptosis index of lung tissue in lymphatic duct ligation groups was significant lower than that in no-ligation groups (Plt;0.05). Levels of endotoxin, D-lactate, and diamine oxidase in lymphatic duct ligation groups had downward trends compared with no-ligation groups, but there was no statistical signification (Pgt;0.05). Conclusions Intestinal ischemia/reperfusion injury of rats can cause intestinal permeability increase, bacterial endotoxin translocation and systemic inflammatory response. Mesenteric lymphatic duct ligation and glutamine enteral nutrition intervention can weak lung tissue damage, increase thickness of intestinal mucosa, maintain intestinal barrier function, reduce endotoxin translocation and attenuate systemic inflammatory response. Enteral nutrition with glutamine was better than normal enteral nutrition.
