Methods: Found out pathology specimens of who diagnosed CD and ITB in our hospital from 2006 to 2012. CD group had 29 cases (25 of endoscopic specimens, 4 of the surgical specimens), ITB group had 14 cases (12 of endoscopic samples, 2 of surgical specimens). Collected 11 cases.of endoscopic specimens as healthy controls. Each specimen cut serial three sections, to do HE, Masson’s dyeing and SHG/TPEF imaging respectively. Use the Image-Pro Plus6.0 to analysis Masson’s dyeing images, calculating the Average optical density
absorbance (AOD), reflecting the expression of collagen fibers. Observed the characteristics of fibers deposition in SHG/TPEF images. Comparison among multiple groups performed Peptide 17 datasheet by a standard one-way analysis of variance,and between groups performed by Dunnett’s T3 multiple. Results: Among CD, ITB and healthy controls groups, the collagen
fibers expression in ITB was highest (AOD = 560.1772 ± 230.6484). Collagen fibers was higher in CD or ITB than healthy controls, P < 0.05. After eliminating surgical selleck screening library specimens, collagen expression was higher in ITB than CD, P < 0.05. In endoscopic biopsy specimens, collagen expression was higher with granuloma (430.2869 ± 187.6046) than without granuloma (273.6598 ± 243.2126), P < 0.05; SHG/TPEF imaging: in surgical specimens of CD and ITB, there were a large number of collagen fibers deposition in the submucosa, and collagen fibers in CD looked like clumps and curling, without obvious regularity, and in ITB rang aroud the caseating granuloma. Collagen fibers could be found scattering around the glands in endoscopic biopsy specimens. Conclusion: It’s valuable to evaluate fibrosis of crohn’s disease and intestinal tuberculosis by Masson’s dyeing and SHG/TPEF imaging and it could be a new way to identify them. Key Word(s): 1.

Many methods have been used to screen for CRC. These includes faecal occult blood test (FOBT), faecal DNA testing & colonoscopy.
