肠道菌群与溃疡性结肠炎

溃疡性结肠炎(UC)是一组病因和发病机制不明的肠道慢性非特异性炎症性疾病。近年来研究认为UC可能主要由遗传基因易感个体决定,免疫反应增强是关键的直接发病机制;并且许多研究都表明肠道菌群在UC的发病机制中起到了重要的启动作用,环境、饮食、精神心理等因素可能是发病的重要诱因。基于此理论,微生态制剂在治疗炎症性肠病中得到广泛的

溃疡性结肠炎患者肠道菌群变化与细胞因子、TLRs分子表达的相关性研究

目的探讨溃疡性结肠炎患者肠道菌群变化与细胞因子、TOLL样受体(Toll-like receptors,TLRs)分子表达的相关性。方法将2015年6月—2016年12月在山东省医学科学院第三附属医院确诊并接受治疗的溃疡性结肠炎患者78例作为试验组,同时选择未患溃疡性结肠炎的80例健康者作为对照组。分别对试验组和对照组进行肠道菌群检测,肠黏膜TLR2、TLR4、TLR5、TLR9分子表达检测和外周血IL-4、IL-6、IL-17、IL-23、TNF-α等炎性细胞因子表达检测,分析炎性细胞因子和TLRs表达与肠道菌群变化的关系。结果试验组双歧杆菌、乳杆菌含量明显低于对照组(P均0.05),拟杆菌、肠杆菌、肠球菌、梭杆菌含量明显高于对照组(P均0.05);试验组肠黏膜组织中TLR2、TLR4、TLR5、TLR9表达明显高于对照组(P均0.05);试验组外周血IL-4表达低于对照组,IL-6、IL-17、IL-23、TNF-α等炎性细胞因子表达高于对照组(P均0.05)。Pearson相关性分析显示,TLR2、TLR4、TLR5、TLR9表达与拟杆菌、肠杆菌、肠球菌含量呈正相关,与双歧杆菌、乳杆菌含量呈负相关;与IL-6、IL-17、IL-23、TNF-α表达呈正相关,与IL-4表达呈负相关。结论溃疡性结肠炎患者正常肠道菌群平衡被打破,促炎因子表达增加,抑炎因子表达减少,TLRs分子表达增加。肠道菌群紊乱可能通过增强TLRs分子表达来促进促炎因子的分泌,介导肠黏膜炎性反应。

Morphological study on colonic pathology in ulcerative colitis treated by moxibustion

AIM:To observe the therapeutic effect of moxibustion on ulcerative colitis and its influence on the colonic mucosal morphology.METHODS:Forty-six patients with ulcerative colitis were randomly divided into the moxibustion with herbal medicine underneath group and the western medicine group. Thirty patients were treated with the above moxibustion and 16 patients with Salicylaye fapyridine (SASP).The colonic mucosa of 13 patients in the moxibustion group was observed by colonoscopy before and after the treatment. Mucin was also analyzed by H.E and AB-PAS staining.RESULTS:Seventeen patients were clinically cured,12 were improved and 1 unchanged in the moxibustion group. In the control group, 5 patients were clinically cured,7 improved and 4 unchanged. Thirteen patients with active UC were taken as the subjects for histopathologic analysis in this study. The colonic mucosal lesions were remarkably improved and the characteristic of the mucin also changed. In most sections, the chronic inflammation of mucosa was geatly ameliorated (P< 0.01). The inflammatory cell infiltratation much decreased and neutrophils, disapeared in most sections (P<0.001). The goblet cells significantly increased (P<0.001); crypt paracrypt abscess or mucosal ulceration was seen(P<0.001).CONCLUSION:The rate of cure of ulcerative colitis by moxibustion with herbal medicine beneath is superior to that by SASP. This sort of moxibustion can effectively improve the colonic mucosal lesions and restore the proportion of mucoprotein to near normal.     

p53 codon 72 polymorphism in patients affected with ulcerative colitis

Background The p53 tumor suppressor protein plays a fundamental role in maintaining genomic integrity through its ability to arrest the cell cycle in G1 and induce apoptosis. The proapoptotic activity of p53 seems to be strictly related to proline-rich regions, homologous to the SH3 binding domain. In the literature, reported data suggest a role for polymorphism at codon 72 of p53 in the predisposition to neoplastic transformation, although the results are still controversial. In this study, we investigated Arg72Pro polymorphism of p53 and related this polymorphism to clinical parameters in patients affected with ulcerative colitis (UC). Methods We studied 243 consecutive outpatients affected with well-established UC. The control group comprised 142 healthy blood donors, with age and sex comparable to those of the patients. Results p53 Pro/Pro was significantly related to the clinical course and duration of disease (odds ratio, 55.8 and 8.8, respectively). Nineteen of 24 patients with Pro homozygosity had a duration of disease >7 years. In contrast, 87 of 123 patients with Arg/Arg had short-standing UC (≤7 yrs) and 66 of 96 with Arg/Pro had short-standing UC (χ-squared, 22.86; P < 0.0001). Thirty-four of 243 patients affected with UC had a positive family history for colorectal carcinoma (CRC). In those patients p53, Pro/Pro was significantly related to a family history of CRC (odds ratio, 38.1). Conclusions These preliminary data suggest that polymorphism at codon 72 of the p53 gene influences the clinical course of UC, with continuous disease associated with p53 Pro homozygosity.
