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.

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 explore the role of GRK5 in sustained β adrenergic receptor (βAR)-stimulated increased levels of oxidative stress.Methods Male SD rats (180-200 g) were separated into 4 groups according to the random principal: control group (CTRL), control with NAC supplement group (CTRL+NAC), ISO treated group (ISO), and ISO treated with NAC supplement group (ISO+NAC), with 6 rats in each group.ISO group was treated by method of intraperitoneal injection for 3 mg/(kg· d).CTRL rats received same volume of physiological saline by same method, while NAC was treated by supplement in drinking water for 15 g/L per day.After 2 weeks of treatment, BP, heart mass index (HMI), histology changes, expression of NOX4 and GRK5 of myocardium was examined.Results HMI of ISO rats was significantly higher than that of the CTRL group [(3.99±0.10 vs 3.31±0.13) mg/g, P＜0.05], and the cardio-myocyte cross-sectional area of ISO group was also significantly increased compared with CTRL group [(11 117.00±387.57 vs 4572.23±176.39) μm, P＜O.05].ISO+NAC significantly reduced the ISO-induced increases of heart weight index (3.56±0.12 mg/g, vs ISO, P＜0.05) and myocyte cross-sectional area (6160.33±141.44 μm2, vs ISO,P＜0.05).The immunohistochemistry results showed that the expression of myocardial NOX4 of ISO group was significantly higher than that of CTRL group [(10.59±1.61 vs 4.35±1.65), P＜0.05], and NAC reduced the ISO induced NOX4 expression increase [(4.67±1.25 vs 10.59±1.61), P＜0.05].Western Blot and immunohistochemistry were used to detect the protein expression of myocardial GRK5.Both results showed that there were no significant differences between ISO and CTRL, ISO+NAC and ISO group (P＞0.05).RT-qPCR detected no significant differences of myocardial GRK5 mRNA expression between ISO and CTRL, ISO+NAC and ISO groups (P＞0.05).Arterial blood pressure showed no significant difference among the 4 groups of rats (P＞0.05).No significant differences were found between rats from CTRL+NAC and CTRL group.Conclusions In the mechanism of sustained βAR-stimulated cardiac hypertrophy, GRK5 may not participate the regulation of hypertrophy-induced factor, and this process needs to be proved in further study.

Objective To screen the prevalence of celiac disease with serologic markers in the central Chinese population,specifically in patients with chronic diarrhea-predominant irritable bowel syndrome (D-IBS).Methods A total of 282 adult patients with D-IBS were selected based on ROME Ⅲ criteria with 296 age and sex matched consecutive healthy individuals as controls.A gluten-free diet (GFD) was advised in subjects positive for IgA/IgG anti-htTG/DGP antibodies and the serologic antibodies were retested after the GFD.Results Among the 578 study subjects,five D-IBS patients (5/282,1.77％) and two healthy controls (2/296,0.68％) were positive for anti-htTG/DGP antibodies.Among the seven positive cases,one was lost to follow-up and only four were evaluated during GFD therapy for an average of 5.2 months with clinical and/or serological manifestations improved.Conclusions The prevalence of celiac disease may not be uncommon in China.Compared with the healthy population,patients with D-IBS tend to be affected more.Thus,it is significantly important to conduct routine screening for celiac disease in patients with D-IBS.

ObjectiveTo explore the characteristics of the cognitive changes in patients with lacunar infarction(LI) after carotid artery stenting(CAS).MethodsNeuropsychological tests were conducted in 43 patients with LI and carotid stenosis before and 1 month,6 months,12 months after CAS and the scores were compared with those of 41 healthy cases.ResultsCompared with control group,MMSE scores ( 26.33 ± 1.94),memory and executive function in therapy group lowered obviously.There was statistical difference (P＜ 0.05 or P＜ 0.01 ).Compared with before CAS,MMSE scores of 1 month (27.17±2.15),6 months (27.17 ±2.15),12 months (28.15±1.98) after CAS,memory and executive function in therapy group were all better obviously.There was statistical difference (P＜0.05 or P＜0.01).ConclusionIn acute stage of patients with LI (with in 1 week),most cognitive impairment was severe. Most cognition disorders was improved to normal level 12 months after CAS.The mechanism may be associated with the improvement of chronic cerebral insufficiency.

Objective To analyze and explore the clinical features,pathological characters,treatment and prognosis of rectum carcinoid.Methods From January 1997 to January 2010,69 pathologically diagnosed rectum carcinoid cases were collected from Union Hospital of Tongji Medical College,Huazhong University of Science and Technology and other 7 hospitals.The clinical features,pathological characters,treatment and prognosis were analyzed. Results Of 69 rectum carconid cases,there were 36 males and 33 females.The average age was (49.3±12.9) years.The common symptom were hemotochezia,abdominal pain,constipation,diarrhoea and abdominal distension.There were 55 cases with lesions from the anus less than 8 cm and in other patients,lesions from the anus were all more than 8 cm.66 cases were typical carcinoid,3 cases were atypical carcinoid.40 cases underwent the immunohistochemical staining.The common markers for immunohistochemical staining were Syn,CgA and NSE,the positive percentage were 90％ (36/40),75％ (30/40) and 82.5％(33/40) respectively.A total of 24 patients received endoscopic therapy,44 patients had surgery,1 patient who refused surgery received only life support and symptomatic treatment.Conclusion No specific clinical symptoms of rectum carcinoid,and most were typical carcinoid.Lesions confined to mucosa and submucosa could be considered the endoscopic therapy.

Objective To study the effect of different dose fractionation on overall survival in patients with limited-stage small cell lung cancer (LS-SCLC). Methods LS-SCLC patients treated with radical combined chemotherapy and radiotherapy (RT) between January 2001 and Dec 2007 were analyzed retrospectively. According to the dose fractionation schemes, patients were divided into three groups:conventional fractionated RT (1. 8 -2.0 Gy,once daily), hyperfractionated RT (1.4 Gy, twice daily) and hypofractionated RT (2. 5 Gy,once daily). Overall survival, disease free survival and pattern of failures of the three groups were compared. A total of 177 patients were enrolled, including 63 patients in conventional fractionated RT group, 79 in hyperfractionated RT group and 35 in hypofractionated RT group. Results The overall follow-up rate was 96. 6%. The patient numbers with follow-up of more than 2 and 5 years were 153 and 92, respectively. The median survival time of the entire group was 22. 4 months, and the 2-and 5-year survival rates were 43.4% and 23. 5%, respectively. The 2-year survival rates for three groups were 31%, 46% and 59% (x2 =7.94,P=0.019), respectively. The 2-year disease free survival for three groups were 20%, 31% and 40% ( x2 = 4. 86, P = 0. 088 ), respectively. In the pairwise comparisons,patients in hypofractionated RT group have better survival than those in conventional fractionated RT group ( x2 = 7. 81, P = 0. 005 ), the effect of hyperfractionated RT group lies between the hypo-and the conventional fractionated RT groups, but no significant differences were detected ( x2 = 2. 31, P = 0. 128; x2 = 2. 95, P =0. 086). The mildest side effect was found in the hypofractionated RT group. No statistically significant differences were found in the patterns of first failure. Conclusion The hypofractionated RT scheme showed potential survival benefits for patients with LS-SCLC and should be considered in the setting of randomized clinical trials.
