METHODS: Paraffin-embedded sections of seven organs (pancreas, stomach, duodenum, esophagus, liver, small intestine and colon) dissected from sprague-dawley (SD) rats and institute of Cancer Research (ICR) mice were prepared. The regional distributions of nesfatin-1/NUCB2 IR cells were observed by immunohistochemical staining. The morphological features of the nesfatin-1/NUCB2 IR cells were evaluated by hematoxylin and eosin (HE) staining. Fresh tissues of the seven organs were prepared for Western blotting to analyze the relative protein levels of NUCB2 in each organ.RESULTS: Immunohistochemical staining showed that the nesfatin-1/NUCB2 IR cells were localized in the central part of the pancreatic islets, the lower third and middle portion of the gastric mucosal gland, and the submucous layer of the duodenum in SD rats and ICR mice. HE staining revealed that the morphological features of nesfatin-1/NUCB2 IR cells were mainly islet cells in the pancreas, endocrine cells in the stomach, and Brunner’s glands in the duodenum. Western blotting revealed that NUCB2 protein expression was higher in the pancreas, stomach and duodenum than in the esophagus, liver, small intestine and colon (P = 0.000). CONCLUSION: Nesfatin-1/NUCB2 IR cells are expressed in the pancreas, stomach and duodenum in rodents. These cells may play an important role in the physiological regulation of carbohydrate metabolism, gastrointestinal function and nutrient absorption.展开更多

This study is performed to determine whether changes in the blood levels of two anorexigenic hormones, leptin and NUCB2/nesfatin-1, can help to diagnose acute appendicitis in children and whether these two parameters can distinguish acute appendicitis from abdominal pain. Methods: Sixty children with comparable ages and body mass indices are divided into three groups of 20 children each: those with acute appendicitis, those with abdominal pain, and controls. The blood sample with acute appendicitis is taken preoperatively (T1), and subsequent samples are taken 24 hrs postoperatively (T2) and 3 days postoperatively (T3). The blood sample with abdominal pain subjects is also taken in the corresponding times with those with acute appendicitis while blood sample from controls is only taken in the T1 corresponding time. Leptin and NUCB2/nesfatin-1 levels are measured by enzyme-linked immunosorbent assay. Results: The serum leptin levels are significantly higher preoperatively than postoperatively in all three groups. The NUCB2/nesfatin-1 levels at T1 in acute appendicitis are significantly higher than those at T2 in all three groups, but are restored at T3 to levels similar to those of controls. Neutrophil percentage has a sensitivity of 100%, and specificity of 76.32%, NUCB2/nesfatin-1 level has a sensitivity of 47% and specificity of 95%, and the leptin level has a sensitivity of 64% and specificity of 51% in the diagnosis of acute appendicitis. Conclusions: High preoperative leptin and NUCB2/nesfatin-1 levels may be a causative factor for appetite suppression observed in patients with acute appendicitis. High preoperative and low postoperative serum leptin and NUCB2/nesfatin-1 concentrations may serve as new candidate biomarkers that help to distinguish acute appendicitis from abdominal pain in children in addition to high CRP concentration, high WBC count, and neutrophilia.展开更多
