ABSTRACT
Objective To explore the effect of enteral nutrition applied to bowel preparation of diabetes patients before electronic colonoscopy. Methods A total of 172 diabetes patients were randomly allocated to the experimental group and the control group with 86 patients in each group. The experimental groups executed no dietary restriction within 3 days before the examination, and received Ensure 1h before colonoscopy. However,the control group was given low residue diet within 3 days before the examination, and received no Ensure before colonoscopy. The enteral cleanness and incidence of hypoglycemic reaction, abdominal pain and horror was compared between the two groups. Results 72 cases(83.72%) of the experimental group and 70 cases (81.40%) of the control group had better enteral cleanness, and there was no statistical difference in intestinal cleanness between the two groups. In the experimental group the incidence of hypoglycemic reaction, abdominal pain, horror was significantly lower than those in the control group. Conclusions Bowel preparation with unrestricted diet and ingested ensure before colonoscopy can not only ensure intestinal cleanness but also enhance endurance of colonoscopy.
ABSTRACT
Cyclooxygenase is the key enzymes mediating prostaglandings release. In recent years, two isoforms of cyclooxygenase, a constitutive cyclooxygenase(COX-1)and an inducible cyclooxygenase (COX-2),have been identified, from which people have known more about gastrointestinal pathophysiology. This article is a review of COX-1 and COX-2 on the distribution, inducement and regulation in gastrointestinal tract and its relation to programmed cell death, tumor, ulcer and Crohn's disease.
