Synchrotron-radiation phase-contrast imaging of human stomach and Gastric cancer: in vitro studies.
Journal of Synchrotron Radiation, 2012Co-Authors: Lei Tang, Li Gang, Ying-shi Sun, Xiao-peng ZhangAbstract:The electron density resolution of synchrotron-radiation phase-contrast imaging (SR-PCI) is 1000 times higher than that of conventional X-ray absorption imaging in light elements, through which high-resolution X-ray imaging of biological soft tissue can be achieved. For biological soft tissue, SR-PCI can give better imaging contrast than conventional X-ray absorption imaging. In this study, human resected stomach and Gastric cancer were investigated using in-line holography and diffraction enhanced imaging at beamline 4W1A of the Beijing Synchrotron Radiation Facility. It was possible to depict Gastric Pits, measuring 5070 mu m, Gastric grooves and tiny blood vessels in the submucosa layer by SR-PCI. The fine structure of a cancerous ulcer was displayed clearly on imaging the mucosa. The delamination of the Gastric wall and infiltration of cancer in the submucosa layer were also demonstrated on cross-sectional imaging. In conclusion, SR-PCI can demonstrate the subtle structures of stomach and Gastric cancer that cannot be detected by conventional X-ray absorption imaging, which prompt the X-ray diagnosis of Gastric disease to the level of the Gastric pit, and has the potential to provide new methods for the imageology of Gastric cancer.

Short segment Barrett's esophagus: Prevalence of helicobacter pylori infection in comparison to patients with erosive GERD, long segment Barrett's esophagus as well as a asymptomatic control group. A prospective evaluation
Gastroenterology, 2000Co-Authors: Dieter Schilling, Hahne M, Tina Weinerth, Andreas Spiethoff, Ralf Jakobs, Juergen F. RiemannAbstract:Updated Sydney System. In 10 patients with marked antral 1M and 10 without 1M, Ki-67 lavelling index (LI) in the antral mucosa was assessed. The immunostaining was performed using MIB-I antibody (Immunotech, Marseille, France) and by the avidin-biotin method with microwave retrieval. LI was calculated by counting MIB-I-positive cells in the entire Gastric Pits longitudinally sectioned and was expressed as a percentage ratio of the total cells in a Gastric pit. Results: Table shows the number of patients in each category of change after the therapy. There was no significant difference in the grade of atrophy or 1M between before and after the therapy. After eradication, Ki-67 LI in the antral mucosa without 1M decreased significantly (from 34 to 25%, p
