OBJECTIVE
To study the expressions changes of gastric mucosal hypoxia-inducible factor-1alpha (HIF-1alpha) and downstream molecules [such as vascular endothelial growth factor (VEGF) and cyclooxygenase-2 (COX-2)] of verrucous gastritis (VG) patients of different Chinese medicine (CM) syndrome types
We studied a cause of postoperative hemorrhagic gastritis in the disease of portal hypertension experimentally. Five portal hypertensive dogs, produced by our whole liver compression procedure, underwent transabdominal devascularization on one-third upper gastric portion. In the gastric cardia,
Introduction: Chronic gastritis is one of the most common diseases in the population. Several factors influence its appearance; however, the effect of high altitude has not been studied thoroughly.
To define the role of the nutrient microvasculature in the pathogenesis of acute gastric mucosal erosions, a correlation was performed of changes in intracellular oxygenation (ICPO2) and intracellular potential difference (ICPD) in surface epithelial cells with the histological alterations in the
Chronic gastrointestinal ischemia (CGI) is the result of decreased mucosal perfusion. Typical histological characteristics are lacking which hamper its early diagnosis. Hypoxia-inducible factor-1α (HIF-1α) is expressed under acute hypoxia. We investigated HIF-1α expression in chronic ischemic and
The study investigated hypoxia-associated markers (HIF-2alpha, Epo, Epo-R, Glut-1 and VEGF) along with Ki-67 in a gastric carcinogenesis model, and the prognostic significance of hypoxia-inducible factor (HIF)-2alpha in surgically treated gastro-oesophageal cancer. Protein expression was examined
Helicobacter pylori (H. pylori) is a human gastric pathogen that has been linked to the development of several gastric pathologies, such as gastritis, peptic ulcer, and gastric cancer. In the gastric epithelium, the bacterium modifies many signaling pathways, resulting in contradictory responses
Objective: To observe the effect of acupoint catgut embedding on histopathological changes of gastric mucosa and expression of mucosal hypoxia inducible factor (HIF)-1α and vascular endothelial growth factor (VEGF) proteins in chronic atrophic gastritis (CAG) rats,
To observe the clinical efficacy of Huazhuo Jiedu formula in treating chronic erosive gastritis (CEG) patients with syndrome of accumulation of turbidity and toxicity, explore its mechanism by observing the changes in expression levels of hypoxia inducible factor (HIF-1α), vascular endothelial
Reactive oxygen species (ROS) attack guanine bases in DNA and form 8-hydroxydeoxyguanosine (8-OHdG), which has been regarded simply as an oxidative mutagenic by-product. On the other hand, our previous report showed paradoxically ROS attenuating action of generated 8-OHdG. In the current study, both
Hypoxia-inducible factor-1 (HIF-1)alpha expression was studied in the gastric carcinogenesis sequence and as a prognostic factor in surgically resected gastric and gastro-oesophageal junction tumours. Protein expression was examined using immunohistochemistry on formalin-fixed biopsies of normal
Helicobacter pylori infection triggers chronic inflammation of the gastric mucosa that may progress to gastric cancer. The hypoxia-inducible factors (HIFs) are the central mediators of cellular adaptation to low oxygen levels (hypoxia), but they have emerged recently as major transcriptional
The phosphatidylinositol-3-kinase (PI3K)/Akt signaling pathway plays an important role in cell proliferation, transformation, apoptosis, tumor growth and angiogenesis. Paclitaxel is commonly used to treat multiple human malignancies; however, the underlying mechanisms of paclitaxel in gastric cancer
The authors discuss two cases in which following abdominal operations in consequence of septic shock, infection and hypoxia, necrosis of the gastric wall developed requiring further operations, subtotal resection of the stomach included. Attention is paid to the factors responsible for full
