Liver transplantation is a conventional treatment for terminal stage liver diseases. However, several complications still hinder the survival rate. Intestinal barrier destruction is widely observed among patients receiving liver transplant and suffering from ischemia–reperfusion or rejection injuries because of the relationship between the intestine and the liver, both in anatomy and function. Importantly, the resulting alteration of gut microbiota aggravates graft dysfunctions during the process. This article reviews the research progress for gut microbial alterations and liver transplantation. Especially, this work also evaluates research on the management of gut microbial alteration and the prediction of possible injuries utilizing microbial alteration during liver transplantation. In addition, we propose possible directions for research on gut microbial alteration during liver transplantation and offer a hypothesis on the utilization of microbial alteration in liver transplantation. The aim is not only to predict perioperative injuries but also to function as a method of treatment or even inhibit the rejection of liver transplantation.

Calorie restriction (CR) is a dietary regimen that reduces calorie intake without incurring malnutrition or a reduction in essential nutrients. It has long been recognized as a natural strategy for promoting health, extending longevity, and prevents the development of metabolic and age-related diseases. In the present review, we focus on the general effect of CR on gut microbiota composition and global metabolism. We also propose mechanisms for its beneficial effect. Results showed that probiotic and butyrate-producing microbes increased their relative abundance, whereas proinflammatory strains exhibited suppressed relative abundance following CR. Analyses of the gut microbial and host metabolisms revealed that most host microbial co-metabolites were changed due to CR. Examples of dramatic CR-induced changes in host metabolism included a decrease in the rate of lipid biosynthesis and an increase in the rates of fatty acid catabolism, β-oxidation, glycogenolysis, and gluconeogenesis. The observed phenotypes and the further verification of the direct link between gut microbiota and metabolome may benefit patients that are at risk for developing metabolic disease. Thus, improved gut microbiota composition and metabolome are potential biomarkers for determining the effectiveness of dietary interventions for age-related and metabolic diseases.

From gut changes to type 2 diabetes remission after gastric bypass surgeries

Increasing evidence suggests that the gut may influence the host’s metabolism and ultimately change the outcomes of type 2 diabetes mellitus (T2DM). We review the evidence on the relationship between the gut and T2DM remission after gastric bypass surgery, and discuss the potential mechanisms underlying the above relationship: gut anatomical rearrangement, microbial composition changes, altered gut cells, and gut hormone modulation. However, the exact changes and their relative importance in the metabolic improvements after gastric bypass surgery remain to be further clarified. Elucidating the precise metabolic mechanisms of T2DM resolution after bypass surgery will help to reveal the molecular mechanisms of pathogenesis, and facilitate the development of novel diagnoses and preventative interventions for this common disease.

人类微生态是寄居在人体中的微生物聚集体,且主要存在于胃肠道(GIT) 中。肠道微生态随着人体发育而演化,并在人类健康和疾病中起着重要作用。近年来,由于微生态会影响宿主代谢、生理学和免疫系统发育,而且微生态紊乱可能导致许多疾病,其越来越受到人们的关注。肠道微生态可能与恶性肿瘤有一定联系,如胃癌和结直肠癌;也可能与其他一些疾病有关,如非酒精性脂肪肝(NAFLD)、被称为工业化世界“生活方式疾病”的肥胖和糖尿病、冠心病以及中枢神经系统紊乱。虽然分子技术革命为我们更准确地研究肠道微生态提供了必要的工具,但是我们需要更精确地阐明其与某些人类疾病病理变化的关系,明确微生态在不同疾病中的作用是新的治疗策略发展的基础。本文概述了肠道微生态对人类健康的重要影响以及调整肠道菌群结构的潜在用途,如菌群移植用于治疗耐药艰难梭菌(C. difficile) 的感染。通过微生态干预调整肠道区域以改善人类健康的概念虽刚刚兴起,但其治疗意义显著。因此,抑制有害菌、促进有益菌可能会保护人类健康,并且这些努力将为探索发展更加合理的治疗方案打下基础。

The gut microbiota is mainly composed of a diverse population of commensal bacterial species and plays a pivotal role in the maintenance of intestinal homeostasis, immune modulation and metabolism. The influence of the gut microbiota on solid organ transplantation has recently been recognized. In fact, several studies indicated that acute and chronic allograft rejection in small bowel transplantation (SBT) is closely associated with the alterations in microbial patterns in the gut. In this review, we focused on the recent findings regarding alterations in the microbiota following SBT and the potential roles of these alterations in the development of acute and chronic allograft rejection. We also reviewed important advances with respect to the interplays between the microbiota and host immune systems in SBT. Furthermore, we explored the potential of the gut microbiota as a microbial marker and/or therapeutic target for the predication and intervention of allograft rejection and chronic dysfunction. Given that current research on the gut microbiota has become increasingly sophisticated and comprehensive, large cohort studies employing metagenomic analysis and multivariate linkage should be designed for the characterization of host–microbe interaction and causality between microbiota alterations and clinical outcomes in SBT. The findings are expected to provide valuable insights into the role of gut microbiota in the development of allograft rejection and other transplant-related complications and introduce novel therapeutic targets and treatment approaches in clinical practice.

一个多世纪以前,科学家们就首次发现了肿瘤区域中细菌的存在。但是,微生物在肿瘤发生中的作用近年来才被认识到。近几十年来,与肠道菌群失调相关的疾病代表了全世界最严重的一些公共卫生问题。大量的流行病学研究表明,肠道菌群与某些常见肿瘤密切相关。然而,肠道菌群与肿瘤相关联的具体分子机制仍不明确。研究表明,肠道菌群的改变有助于确定肝癌、酒精相关肝病、非酒精性脂肪肝和肝硬化的发生和发展。鉴于益生菌是一种可通过调节免疫系统促进人类健康的药物,其可能会为肝细胞癌(HCC) 和非酒精性脂肪肝的治疗提供新方向。本文总结了肠道菌群在肿瘤及肝病中的研究进展,综述了肠道菌群与肿瘤和肝病之间的关系。此外,考虑到细菌内稳态的重要性,我们也对益生菌进行了概述,旨在为相关疾病的治疗提供指导。
