Objective To retrospectively study histopathologic features of ulcerous colitis (UC) and Crohn's disease (CD) by endoscopic biopsy. Methods Data of age, gender and intestinal involvement of 106 cases of CD and 180 cases of UC confirmed by pathology were reviewed. Mucosal architecture, chronic inflammation, acute inflammation and epithelial features were evaluated based on histopathological criteria.These features were compared between the two groups. Results Compared with CD cases, UC showed significantly higher percentage of architectural disorders ( P ＜ 0. 05 ), lower percentage of discontinuous chronic inflammation ( P ＜ 0. 05 ) and higher incidence of cryptitis, crypt abscesses and polymorph cells in lamina propria (P ＜0. 05 ), and higher rate of epithelium damage, flattened and less mucous cell as well. Granuloma, pseudo pylorus glands metaplasia and narrow ulcer only occurred in CD cases. Lesions of 90% (162/180) cases of UC were limited to colon, while those of 28% (30/106) of CD cases to ileocecum, and those of 56% (59/106) CD cases involved different parts of gastrointestinal tract. Conclusion Diagnosis of CD and UC needs comprehensive analysis. Diagnostic evidence for CD includes focal involvement of ileocecum, the multifocal involvement in gastrointestinal tract, granuloma, discontinuous inflammation, pyloric gland metaplasia, while that for UC includes mucosal damage limited to colon, continuous chronic inflammation, architectural disorders, or epithelial damage.

A protein designated as Flammulina Velutipes (FV) protein was isolated from the cultured mycelium of FV and purified to homogeneity by CM cellulose CM 52 and gel filtration chromatography. The molecular weight of FV protein were found to be 1.75?10~4u with pI 4.3. Amino acid analysis of FV protein indicated the presence of 14 kinds of amino acids, especially rich in Glu, Asp and Thr.Potent inhibitory effect of FV protein on thrombus formation, in the blood was observed in vitro when rats were given intravenously. The length of thrombus was shortened and the dry weight of the thrombus decreased significantly at the dose of 7.5?10~(-7) mol/kg. Thrombus formation was completely inhibited at the dose of 10~()-8 mol/kg. The IC_(50) was found to be 4.4?10~(-7) mol/kg. FV protein was shown to inhibit collegen induced aggregation of rat platelets both in vitro and in vivo. Its concentration for complete inhibition in vitro was 7.5?10~(-5) mol/L. The IC_(50) was found to be 4?10~(-5)mol/ L. However, FV protein dose of 1.25?10~(-5) mol/kg was required for 60% inhibition in vivo

Objective To re evaluate the diagnosis and outcome in patients with inflammatory bowel disease (IBD) by long term follow up at Wuhan University Zhongnan Hospital in Wuhan, China. Methods One hundred patients with ulcerative colitis (UC) and 15 with Crohn's disease (CD) treated in this hospital from 1980 to 1999 were re evaluated with the uniform diagnostic criteria proposed by National Workshop of Chronic Non infectious Intestinal Diseases, 1993. All patients were followed up by questionnaire, telephone and face to face interview 1～16 years after the initial diagnosis. Results Of 115 patients with IBD, 75(65%) were available for follow up study. Of 64 cases of UC, 46 had their diagnosis confirmed, 9 diagnosed as possible UC, and 9 cases were reclassified as other diseases. Of 11 cases with CD, 7 were diagnosed correctly, 2 were possible CD, and 1 were intestinal tuberculosis. In the remaining 55 UC, 3 died and 1 due to complication of UC. Other 52 UC, 37 had relapse. In the 10 patients with CD, 1 died due to complication. In other 9 cases 7 had relapse. In 46 patients with UC and 6 patients with CD there were symptom free or symptoms improved. Conclusions At follow up 1 to 16 years after the diagnosis of IBD, the initial diagnosis of UC and CD was confirmed in 86% and 82% respectively. Relapse rates of UC and CD were 71% and 78% respectively. The prognosis of patients with UC is better with 88% symptom free and improvement, while only 67% of patients with CD were symptom free and symptoms improved.

Objective: To study the impact of ticagrelor on inlfammatory factors in patients with unstable angina pectoris (UAP) after percutaneous coronary intervention (PCI).
Methods: Based on conventional medication, a total of 100 UAP patients after PCI were randomly divided into 2 groups for anti-platelet therapy:Treatment group, the patients received aspirin+ticagrelor and Control group, the patients received aspirin+clopidogrel. n=50 in each group, all patients were treated for 12 months. Plasma levels of inlfammatory factors were examined before treatment and 24h, 7d, 28d after the operation. The patients were followed-up for 12 months for ischemic events, bleeding events and adverse drug reactions.
Results: Before treatment, plasma levels of IL-6, IL-18, TNF-α, PDGF were similar between 2 groups (t=0.1356, 0.1668, 0.2473, 0.5780, all P>0.05). At 24h post-operation, the above inlfammatory factors were signiifcantly increased by peaks in both groups and decreased thereafter. At 24h, 7d and 28d post-operation, the levels of IL-6, IL-18, TNF-a, PDGF in Treatment group were all lower than Control group at each corresponding time point (at 24 post-operation, t=2.0856, 2.4399, 2.2217, 2.2053, all P<0.05), (at 7d post-operation, t=6.0978, 5.9705, 4.4631, 4.3963, all P<0.01) and (at 28d post-operation, t=9.3779, 9.7724, 5.5855, 6.1700, all P<0.01). The follow-up study presented that at 12 months post-operation, the ischemic events in Treatment group was lower than Control group (χ2=4.3956, P<0.05);there were no small hemorrhage or major bleeding events occurred;the slight adverse drug reaction was similar between 2 groups (χ2=0.1773, P>0.05).
Conclusion: Compared to clopidogrel, ticagrelor could better decrease plasma levels of inlfammatory factors, it may reduce ischemic events without elevate bleeding events.
