Polyphenols intervention is an effective strategy to ameliorate inflammatory bowel disease: a systematic review and meta-analysis

Abstract

Whether polyphenols could ameliorate inflammatory bowel disease (IBD) is still conflicting. To explore the efficacy of polyphenols as an adjuvant therapy for IBD, we conducted this systematic review and meta-analysis. Literature search was performed using PubMed, Web of Science, Scopus and Cochrane databases. Finally, 12 randomized controlled trials (RCTs) were included. In contrast to control group, curcumin treatment significantly improved clinical remission in intention-to-treat (ITT) (OR = 3.36, 95% CI: 1.09–10.37) and per-protocol (PP) analysis (OR = 5.13, 95% CI: 1.84–14.27). Meanwhile, curcumin could significantly ameliorate endoscopic remission (OR = 5.69, 95% CI: 1.28–25.27) and clinical response (OR = 4.69, 95% CI: 1.03–21.47) in PP analysis. Heterogeneity was present across the studies. In conclusions, polyphenols might be an effective adjuvant treatment for ameliorating IBD. Considering the relatively few studies included in our present study, further clinical trials are required to verify the effects of polyphenols on IBD.     

TL1A:一个新的TNF家族成员

TL1A是肿瘤坏死因子超家族的一个新亚群。通过与受体DR3和DcR3/TR6的结合,既可诱导细胞凋亡,也能活化NF-ΚB。在淋巴细胞、单核细胞/巨噬细胞的活化和增殖,炎症反应的调节、机体的免疫应答以及动脉粥样硬化、炎症性肠病等疾病的发生、发展中起重要作用。     

Non-adenomatous colorectal polyposis syndromes

Gastrointestinal polyps are common lesions that usually present singly or in small numbers. Although the term ‘multiple colorectal polyposis’ was originally applied to patients carrying at least 100 large intestinal adenomas, it has subsequently become broadened to include patients carrying multiple polyps regardless of their nature. Most of the non-adenomatous polyposis syndromes are hereditary. They can be classified according to the dominant type of polyp, their distribution in the gastrointestinal tract and their potential for the development of gastrointestinal cancers. This review summarises their main clinical, genetic and histopathological features.     

Peripheral blood mononuclear-cell interleukin-2 production,receptor generation and lymphokine-activated cytotoxicity in inflammatory bowel disease

The interleukin-2 pathway is essential for the normal immune response to antigen stimulation; we have examined the possibility that this may underlie abnormal peripheral blood lymphocyte immunoregulatory function that has been observed in patients with inflammatory bowel disease. We studied 11 patients with Crohn's disease and 5 with ulcerative colitis, all with quiescent disease activity. Peripheral blood mononuclear cells were isolated from these patients and from healthy age- and sex-matched controls. Interleukin-2 production after mitogen and phorbol-myristate acetate stimulation was similar in both groups: 381±71 (mean ± SE) U/ml by control cells and 451±70 by patient cells. Interleukin-2 receptor generation was also measured pre- and poststimulation by labeling with anti-Tac antibody. This was 10.45±1 and 69.95±3.85% for control cells and 11.41±1.38 and 60.9±4.25% for patients cells. Finally, we examined the response of these cells to interleukin-2 stimulation by generating cells with direct cytotoxicity to⁵¹Cr-labeled Daudi-cell targets. Control cells caused 59.5±46%⁵¹Cr release, whereas patient cells caused 50.8±5.18% release. None of the above results achieved statistical significance. We conclude that the peripheral blood interleukin-2 pathway is normal in inactive inflammatory bowel disease.

溃疡性结肠炎患者炎性因子水平、肠道菌群分布及发病相关因素分析

目的研究溃疡性结肠炎患者的炎性因子水平、肠道菌群分布及发病相关危险因素,为溃疡性结肠炎的防治工作提供科学依据。方法以2020年6月至2021年5月在文昌市某医院就诊的溃疡性结肠炎患者作为病例组,同时选取(按年龄相差0.5岁,性别相同招揽志愿者参与本研究)同期在该医院进行健康体检者作为对照组。所有研究对象进行问卷调查、肠道菌群检测及炎症因子检测,采用描述性分析方法对2组相关指标进行比较,并对溃疡性结肠炎发病影响因素进行单、多因素分析。结果共纳入溃疡性结肠炎病例(病例组)和健康体检者(对照组)各200例,男性各99例,女性各101例,病例组平均年龄(43.17±8.72)岁,对照组平均年龄(43.54±9.11)岁,2组的年龄、性别分布差异均无统计学意义(均P>0.05)。病例组主要检出的双歧杆菌、乳杆菌数量低于对照组,拟杆菌、肠杆菌、肠球菌、梭杆菌数量高于对照组(均P<0.01)。病例组除白细胞介素(IL)-4水平低于对照组,IL-6、IL-17、IL-23以及肿瘤坏死因子-α(TNF-α)均高于对照组(均P<0.01)。饮酒(OR=3.526)、吸烟(OR=1.272)、饮食不洁(OR=4.592)、存在合并感染(OR=2.146)、情绪紧张(OR=3.919)均为溃疡性结肠炎发病的危险因素。结论溃疡性结肠炎患者肠道菌群种类、数量分布不平衡,血清炎症因子水平明显上升。良好的生活行为习惯以及积极地健康教育可降低溃疡性结肠炎的发生风险。

Malignant fibrous histiocytoma of the lung in a child

We describe a 12-year-old patient with a primary pulmonary mass in the left upper lung. The diagnosis of inflammatory pseudotumour was suspected preoperatively. After pathological examination and complete clinical evaluation, a diagnosis of malignant primary pulmonary fibrous histiocytoma was established. This is a very uncommon primary neoplasm of the lung and to our knoweledge only five paediatric cases have been reported. Because of the rarity of these sarcomas and histological similarities to benign inflammatory pseudotumour, care must be taken to avoid confusion between the two disorders particularly in intra-operative frozen sections. Conclusion Primary malignant fibrous histiocytoma of the lung is an uncommon tumour that should be considered in the differential diagnosis of pulmonary neoplasms of childhood. The histological diagnosis can be difficult due to the similarities with␣inflammatory pseudotumour. Received: 29 May 1996 / Accepted: 21 July 1996
