Ghrelin, a novel gastrointestinal peptide with 28 amino acids, is secreted from the A-like cells of the gastric fundus. This peptide hormone does not only promote the release of growth hormone, but also stimulates food intake, gastric motility and cardiac output. Increased plasma ghrelin level has been reported in patients with upper gastrointestinal (GI) disease or in their disease animal model, suggesting its important role in the pathogenesis of upper GI disease.

OBJECTIVETo understand the clinical features of gastrointestinal cow's milk allergy in children, and to assess the importance of cow's milk challenge.
METHODAn analysis was performed on the clinical manifestations and the challenge results of 50 children who received cow's milk challenges after admission to the department of gastroenterology, Children' s Hospital of Zhejiang University School of Medicine from January,2009 to December, 2012. The value of immunoglobulin E antibody was also analyzed among the 50 children, 25 cases were male and the other 25 were female. The youngest subject was 1. 6 months old, and the oldest was 20 months, most of the cases were younger than 6 months (36 cases).
RESULT(1) Diarrhea (27 cases, 54%) and hematochezia (25 cases, 50%) were the most common clinical features, vomiting, hematemesis and abdominal distention were rare. (2) Cow's milk challenges failed in 58% of the cases, 90% of whom showed delayed allergy. Diarrhea (19 cases, 73%) was the major later presentation, whereas the immediate hypersensitivity showed angio-edema, gastrointestinal symptom and rash. (3) The neutrophil count ((3.8 ± 2.8) x 10(9)/L vs. (2.5 ± 1.3) x 10(9)/L) was higher after challenge among children who failed the challenge. The change in the count of blood cell, neutrophil and platelet was studied, however, there were no statistical differences between the challenge-failed children and the passed ones. (4) Forty-seven cases had milk specific immunoglobulin E antibody test, and 5 showed positive results, 4 of whom were seen among the challenge-failed children.
CONCLUSIONDiarrhea and hematochezia was the most common clinical manifestation, and cow's milk protein induced proctocolitis was the most common disease in practice. It is important and necessary to perform cow's milk challenge.

The gastrointestinal stromal tumor (GIST) is a mesenchymal tumor of the digestive tract showing differentiation along the line of interstitial cell of Cajal. The most GISTs in the stomach generally show the appearance of submucosal tumors. It is rare for GISTs to appear as a pedunculated polypoid lesion on endoscopy. We experienced a case of a 51-year-old man who had a pedunculated polypoid GIST. He was admitted to our hospital for nausea, vomiting, melena and severe anemia (hemoglobin 3.4 g/dL, hematocrit 10.8%). An upper endoscopy showed gastroduodenal intussusception due to a pedunculated polypoid mass. This report presents a rare case of endoscopically proven gastroduodenal intussusceptions due to pedunculated polypoid GIST in the stomach.

Animal gastrointestinal tract contains a complex community of microbes, whose composition ultimately reflects the co-evolution of microorganisms with their animal host. The gut microbial community of humans and animals has received significant attention from researchers because of its association with health and disease. The application of metagenomics technology enables researchers to study not only the microbial composition but also the function of microbes in the gastrointestinal tract. In this paper, combined with our own findings, we summarized advances in studying gastrointestinal tract microorganism with metagenomics and the bioinformatics technology.

The clinical manifestations of intestinal tuberculosis are non-specific. But, abdominal pain, low grade fever, weight loss, anorexia, and diarrhea are major symptoms of intestinal tuberculosis. Massive bleeding has been reported as a rare manifestation of intestinal tuberculosis. Massive hematochezia from intestinal tuberculosis has rarely been reported in the medical literature. Also, most of them were treated with anti-tuberculosis medication only or with surgery. We treated a case of intestinal tuberculosis presenting massive hematochezia with colonoscopic coagulation therapy and anti-tuberculosis medication. Here, we report a Korean man who presented with massive hematochezia from ileal tuberculosis and treated by endoscopic coagulation therapy.

Gastrointestinal system involvement is one of the principal complications seen in the recipients of hematopoietic stem cell transplantation (HSCT), and it is also a major cause of morbidity and death in these patients. The major gastrointestinal complications include typhlitis (neutropenic enterocolitis), pseudomembranous enterocolitis, viral enteritis, graft-versus-host disease, benign pneumatosis intestinalis, intestinal thrombotic microangiopathy, and post-transplantation lymphoproliferative disease. As these patients present with nonspecific abdominal symptoms, evaluation with using such imaging modalities as ultrasonography and CT is essential in order to assess the extent of gastrointestinal involvement and to diagnose these complications. We present here a pictorial review of the imaging features and other factors involved in the diagnosis of these gastrointestinal complications in pediatric HSCT recipients.
