Objective To evaluate the effectiveness and safety of probiotic agents for ulcerative colitis. Methods We searched electronically the Cochrane Central Register of Controlled Trials (Issue 1, 2007), MEDLINE (1978 to 2007), EMBASE (1978 to 2007), OVID Database (1978 to 2007), Chinese Biological Medicine Database (CBM Disc) (1978 to 2007), CNKI (1979 to 2007), Chinese VIP Database (1989 to 2007) and Wanfang Database (1978 to 2007). We also checked the reference lists of retrieved articles and hand-searched 4 kinds of important journals to identify randomized controlled trials of probiotic agents for ulcerative colitis. Meta-analyses were conducted with The Cochrane Collaboration’s RevMan 4.2 software. Results Thirteen trials involving 1146 patients were included. Meta-analyses showed that probiotic agents were not superior to aminosalicylates for the clinical remission rate (OR 0.93, 95% CI 0.53 to 1.66; P=0.82); but the combination of probiotic agents and aminosalicylates were superior to aminosalicylates alone (OR 2.69, 95% CI 1.57 to 4.61; P=0.0003). In terms of the clinical relapse, the rate for probiotic agents was superior to that for placebo (OR 0.03, 95% CI 0.00 to 0.15; Plt;0.0001); but not superior to aminosalicylates (OR 0.95, 95% CI 0.65 to 1.38; P=0.79). The combination of probiotic agents and aminosalicylates was not superior to aminosalicylates alone (OR 0.57, 95% CI 0.24 to 1.32; P=0.19). As for the incidence of adverse effects, probiotic agents were not superior to aminosalicylates (OR 0.85, 95% CI 0.43 to 1.70; P=0.65); and the combination of probiotic agents and aminosalicylates was not superior to aminosalicylates alone (OR 0.30, 95% CI 0.06 to 1.54; P=0.15). Conclusion Probiotic agents are not superior to aminosalicylates based on the evidence in this review, but the combination of probiotic agents and aminosalicylates is superior to aminosalicylates alone in maintaining remission. Probiotic agents are superior to placebo but not superior to aminosalicylates, and the combination of probiotic agents and aminosalicylates is not superior to aminosalicylates alone in preventing relapse. Probiotic agents have good tolerability. However, all these findings should be interpreted with caution and more clinical trials are needed.
ObjectiveTo investigate the significance of endoscopic punctiform erosion around appendiceal orifice with diffused inflammation in left semicolon in the diagnosis of ulcerative colitis. MethodsTwenty-nine patients with endoscopic punctiform erosion around appendiceal orifice with diffused inflammation in left semicolon treated in West China Hospital from January 2007 to November 2012 were included in our study.Patients with either edema,ulcer,polyps around the appendiceal orifice,inflammation in the ascending colon or transverse colon,or segmental inflammation in left semicolon were excluded.The endoscopic characteristic changes and the final diagnosis were compared by means of the pathological biopsy. ResultsOf the total 29 patients with characteristic changes under the endoscope,26 patients were eventually diagnosed to have left-sided ulcerative colitis,one was identified to be with Cronh's disease,and the remaining two patients could not be classified. ConclusionOur findings suggest that the characteristic changes under the endoscope may help the diagnosis of ulcerative colitis.
ObjectiveTo elucidate the characteristics of colonic Crohn’s disease (CD) and evaluate effectiveness of surgical treatment.MethodClinical data of 28 cases with colonic CD who underwent surgery at West China Hospital of Sichuan University between Feb. 2009 and Jan. 2017 were retrospectively analyzed.ResultsDefinite diagnosis of colonic CD was performed in 12 cases preoperatively (42.9%), but 16 cases (57.1%) were misdiagnosed as other disease, ulcerative colitis (5 cases, 17.9%), tumor (4 cases, 14.3%), appendiceal disease (4 cases, 14.3%), and intestinal tuberculosis (3 cases, 10.7%) were the major causes of preoperative misdiagnosed disease. Of the 28 cases, elective surgery was performed in 26 cases and emergency surgery in 2 cases. The major surgical procedures were segmental colectomy(10 cases) and right hemicolectomy (6 cases), as well as ilecolostomy (9 cases), colocolostomy(6 cases), ileostomy(9 cases), colostomy (6 cases), and so on. The length of the first hospital stay of operation related to intestinal lesions in this group was 5–74 d (mean of 25.4 d). Postoperative complications were occurred in 9 cases (32.1%), all these cases didn’t receave medical treatment. Twenty cases were followed up, and the follow-up time was 7–78 months (mean of 33.4 months), 8 cases lost follow-up. The prognosis of the follow-up cases was good.ConclusionsColonic CD has occult clinical manifestation, resulting in misdiagnosis and mistreatment. Segmental resection of the colon is the important treatment for colonic CD. For patients with complications, multidisciplinary diagnosis and treatment is necessary. In addition, systematic medical treatment before surgery helps to reduce the risk of the first surgery associated with intestinal lesions.

【摘要】 目的 采用循证医学的方法评价硫唑嘌呤（aiathioprine，AZA）治疗溃疡性结肠炎（ulcerative colitis，UC）的有效性和安全性。 方法 计算机检索PubMed、Cochrane library、Embase、CNKI、维普和CBM数据库收集国内外关于AZA诊疗UC的随机对照试验（ramdomized controllel trial，RCT）。按Cochrane系统评价的方法评价纳入研究质量，并进行Meta分析。 结果 共纳入5个RCT，共262例UC患者。Meta分析结果显示，AZA治疗UC在缓解率方面与安慰剂比较，差异无统计学意义[P=1.19，95%CI（0.94，1.49），P=0.14]；在复发率方面，两者比较差异有统计学意义[P=0.72，95%CI（0.54，0.95），P=0.02]；全部不良反应方面和严重不良反应方面，两者比较差异无统计学意义，Meta分析结果分别为[P=2.52，95%CI（0.82，7.74），P=0.11]和[P=4.03，95%CI（0.88，18.53），P=0.07]。 结论 系统评价结果为AZA在疗效方面优于安慰剂，在不良反应发生率方面差异无统计学意义。但由于纳入的5个研究中没有高质量的RCT，且有1个可能产生高度偏倚，使得这一结论受到影响，有必要开展更多设计严谨，大样本、多中心的RCT。【Abstract】 Objective To assess the efficacy and safety of azathio-prine in the treatment of ulcerative colitis through an evidence-based method. Methods We searched the literature from databases like PubMed, Cochrane library, CNKI, VIP, and CBM, and evaluated the quality of studies according to Cochrane systematic review. Finally, Meta-analysis was performed. Results Five randomized controlled trials (RCT) were included in this study with a total of 262 patients. Meta-analysis showed that there was no significant difference in the rate of remission between azathio-prine and placebo in treating ulcerative colitis [P=1.19, 95%CI (0.94, 1.49),P=0.14]. There was significant difference in the relapse rate between the two treating methods [P=0.72, 95%CI (0.54, 0.95),P=0.02]. In addition, there was no statistical difference in all adverse effects [P=2.52, 95%CI (0.82, 7.74),P=0.11] and serious adverse effects [P=4.03, 95%CI (0.88, 18.53),P=0.07] between the two treating methods. Conclusion In the treatment of ulcerative colitis, azathio-prine has a significant advantage in efficacy than placebo, but there is no significant difference in the rate of adverse events between the two groups. However, none of the 5 RCT included in this review has a high quality and one of them even probably has a high bias, which has a big influence on our conclusion. Consequently, multi-center large-scale randomized controlled trials of higher quality are needed to make confirmation.
ObjectiveTo summarize the recent progress in studies of intestinal immunity in inflammatory bowel disease (IBD). MethodsThe literatures on studying the intestinal immunity in IBD, including ulcerative colitis and Crohn disease were reviewed and analyzed. ResultsIBD comprised two main diseases that cause inflammation of the intestines: ulcerative colitis and Crohn disease. Although the diseases had some features in common, there were some important differences in clinical symptoms and pathological features. Accumulating evidence suggested that IBD results from an inappropriate inflammatory response to intestinal microbes in a genetically susceptible host. Immunity studies highlighted the importance of host-microbe interactions in the pathogenesis of these diseases. Prominent among these findings were genomic regions containing nucleotide oligomerization domain 2 (NOD2), autophagy genes, miRNAs, and components of the interleukin-23/type 17 helper T-cell (Th17) pathway. The disfunction of the intestinal microbiome, intestinal epithelium, intestinal immune cells, and the intestinal vasculature played a key role in the process of IBD. The treatment with monoclonal antibody had been introduced to treat IBD and had been certificated effective. ConclusionThe study of basic intestinal immunity and regulation network of molecules in pathogenic process of IBD provides theory basis on prevention of IBD, while related genes of IBD can offer more gene therapy targets.
Objective To explore the value of fecal calprotectin （FCP） in the activity evaluation for ulcerative colitis （UC）. Methods Sixty three patients with UC （UC group） and 30 patients with gastrointestinal symptoms but without abnormal results of colonoscopy （control group）， who were treated in The Forth Affiliated Hospital of China Medical University between Sep. 2007 to Dec. 2009 were enrolled to examine the FCP， C-creative protein （CRP）， and erythrocyte sedimentation rate （ESR）. Then comparison between UC group and control group was performed. Results Levels of FCP and CRP in active gradeⅠ，Ⅱ， and Ⅲ group were all significantly higher than those of control group and inactive UC group （P＜0.05）， with the increase of active grade of UC， the level of FCP gradually increased （P＜0.05）. The levels of CRP in active grade Ⅱ and Ⅲ group were all significantly higher than those of gradeⅠgroup （P＜0.05）， but didn’t differed between active grade Ⅱ and Ⅲ group （P＞0.05）. There were no significant difference among 5 groups on ESR （P＞0.05）. Levels of FCP （rs=0.807， P＜0.01）， CRP（rs=0.651， P＜0.01）， and ESR （rs=0.371， P＜0.05） in active grade group were significantly related to histological grade under colonoscopy. Conclusion FCP examination is simple， inexpensive， repeatable， and noninvasive， and FCP can be used as an marker of activity evaluation in UC.
