All the 9 patients had polyps distributed from stomach to large bowel, a total of 725 polyps were resected endoscopically. pathological results: 51 cases had been proved to be hamartomatous polyps, 12 cases had adenomatous polyps and 2 cases BGB324 mw had well differentiated

adenocarcinoma. Conclusion: Early diagnosis, early treatment and follow-up of great concern to the patients with PJS. Positive treatment of polyps endoscopically was the main method to improve the long-term outcome of PJS. Key Word(s): 1.

Objective: To quantify expression of TLR4/NF-κB/IL-6

in ulcerative colitis and to investigate its role involving pathological mechanisms. Methods: The ulcerative colitis model was induced by 2, 4, 6-trini-trobenzenesulfonic acid (TNBS). Twenty-four SPF male Balb/c mice were randomly and equally divided into normal control group and model group. Rats were observed body weight changes, gross and histopathological changes. The TLR4 mRNA expression was detected by RT-PCR; The expression of NF-κB protein was detected by Western-blot; The expression of IL-6 in mice plasma was detected by ELISA method. Results: Compared with normal mice, the ulcerative colitis model with varying degrees of diarrhea and blood in stool, colonic selleck screening library mucosal hyperemia, edema, inflammation, showing a larger ulcer lesions. The ulcerative colitis model colon tissue TLR4 mRNA expression increased; NF-κB protein expression also increased significantly; IL-6 level in serum, model group (47.10 ± 15.72 ng/ml) had a significantly higher than control group (41.48 ± 6.33 ng/ml, P < 0.05). TLR4 mRNA expression, NF-κB protein expression and IL-6 level were significantly selleck chemicals positive correlated (r = 0.79, P < 0.01). Conclusion: In ulcerative

colitis, The expression of TLR4, NF-κB and IL-6 were up-regulated significantly, Activation of TLR4/NF-κB/IL-6 signal pathway may be a important mechanism. Key Word(s): 1. ulcerative colitis; 2. TLR4; 3. NF-κB; 4. IL-6; Presenting Author: HUI DING Corresponding Author: HUI DING Affiliations: Renji Hospital Objective: More than 3/4 of colorectal cancer develops from colorectal adenoma. There is a theory about colorectal cancer’s stage development of “normal epithelium-adenoma-cancer”, DNA methylation plays an important role in it. Folic acid is one-carbon units carrier which impacts DNA methylation. Folate level of colorectal epithelial cell can be reflect by serum folate level accurately. There are about the protective effect of folic acid from randomized trials.
