The high prevalence of diabetes and diabetic complications has caused a huge burden on the modern society. Although scientific advances have led to effective strategies for preventing and treating diabetes over the past several decades, little progress has been made toward curing the disease or even getting it under control, from a public health and overall societal standpoint. There is still a lack of reliable biomarkers indicative of metabolic alterations associated with diabetes and different drug responses, highlighting the need for the development of early diagnostic and prognostic markers for diabetes and diabetic complications. The emergence of metabolomics has allowed researchers to systemically measure the small molecule metabolites, which are sensitive to the changes of both environmental and genetic factors and therefore, could be regarded as the link between genotypes and phenotypes. During the last decade, the progression made in metabolomics has provided insightful information on disease development and disease onset prediction. Recent studies using metabolomics approach coupled with statistical tools to predict incident diabetes revealed a number of metabolites that are significantly altered, including branched-chain and aromatic amino acids, such as isoleucine, leucine, valine, tyrosine and phenylalanine, as diagnostic or highly-significant predictors of future diabetes. This review summarizes the current findings of metabolomic studies in human investigations with the most common form of diabetes, type 2 diabetes.

Sepsis is a common cause of death in hospitalized patients worldwide. The early detection of sepsis remains a great challenge for clinicians, and delayed diagnosis frequently undermines treatment efforts, thereby contributing to high mortality. Omics technologies allow high-throughput screening of sepsis biomarkers. This review describes currently available and novel sepsis biomarkers in the context of genomics, transcriptomics, proteomics, and metabolomics. The combination of these technologies can help refine the diagnosis of sepsis. This review paper serves as a reference for future studies that employ an integrated, multi-omics approach to disease identification.

有效性评价是发现中药药效物质基础、先导化合物和质量标志物的重要前提,因此急需建立一种生物学语言,将中药有效性科学地表达出来,进一步凸显中医药的实用价值。证候和方剂是中医药的重要组成部分,与中药有效性直接相关。我们以证候和方剂为研究对象,建立了科学评价中药有效性的创新方法学体系——中医方证代谢组学。它将中药血清药物化学理论与代谢组学技术有机整合,在解决证候生物标记物的基础上,建立方剂药效生物评价体系,发现并确认中药药效物质基础。该策略为提高中医理论和临床实践的科学价值提供了有力支持。本文概述了中医方证代谢组学的研究策略,利用该方法揭示临床常见中医证候生物标记物及开展相关方剂的有效性评价研究,着重阐述了中药药效物质基础及质量标记物的发现。

多糖广泛存在于草本植物中,具有多种活性,特别是具有免疫调节作用和改善代谢紊乱的作用。然而,其潜在机制还没有被很好地诠释。功能代谢组学越来越多地被用于通过鉴定具有特定功能的代谢产物来研究多糖对宿主的系统性影响。本研究采用功能代谢组学策略,探讨黄芪多糖(Astragalus polysaccharide, APS)代谢获益的潜在机制。在为期8 周的高脂肪饮食(high-fat diet, HFD)喂养的肥胖小鼠中测定了APS的作用。然后,进行基于气相色谱-飞行时间质谱(gas chromatography-time-of-flight mass spectrometry, GC-TOFMS)的非靶向代谢组学分析血清和肝组织,并进行基于液相色谱- 串联质谱(liquid chromatography-tandem mass spectrometry, LC-MS/MS)的靶向代谢组学分析。使用体外和体内代谢紊乱模型测试了代谢产物的潜在功能。我们的结果首次证实了APS对肥胖小鼠的代谢益处。然后,代谢组学分析显示,补充APS 可逆转HFD 诱导的代谢变化,并确定2-羟基丁酸(2-hydroxybutyric acid, 2-HB)是APS活性的潜在功能性代谢产物,该代谢物被HFD显著降低,并被APS逆转。进一步研究表明,2-HB可抑制油酸(oleic acid, OA)诱导的甘油三酯(triglyceride, TG)累积。还发现其可刺激肝细胞中脂质降解蛋白的表达和3T3-L1 细胞中的TG脂解。此外,在高脂肪和高蔗糖(high-fat and high-sucrose, HFHS)喂养的小鼠中发现2-HB可降低血清TG并调节参与脂质降解的蛋白质。总之,我们的研究表明,APS的代谢
益处至少部分归因于2-HB 的产生,2-HB 在体外和体内均可调节脂质代谢。我们的结果同样证实,功能代谢组学在研究植物多糖系统益处的潜在机制方面是切实可行的。

中药(TCM)是一种天然来源的复杂体系,具有多种多样的化学成分,在中国被广泛应用。中药的质量控制对政府和检测机构来说是一项巨大的挑战,涉及大量科学问题,包括:中药中有多少成分?如何全面地描述中药的诸多成分以及随后如何表征这些成分?为了推荐对照品的选择,这些(活性)代谢产物在多成分中药中的水平和范围是什么?以及选择的指标成分成分需要哪些质量要求,并且从实用的角度看,如何以低成本在短时间内对这些成分进行定量评价?所有这些因素均需要深思熟虑,才能理解中药独特的化学性质,从而提高中药质量标准,从而为患者提供更好的和更稳定的药物治疗。为了回应这些科学问题,本文汇总了有关中药化学分析技术和方法的最新探索性研究。这些方法的进展包括针对液相色谱- 高分辨质谱(LC-HARMS)联用技术的多维分离、LC-HRMS 联用技术的智能触发数据依赖型采集、利用液相色谱- 质谱联用技术(LC-MS)进行靶向分析、超临界流体色谱以及大的质谱(MS)数据集的数据挖掘。此外,为了节省对照品和中药质量标准的分析时间,本文提出了两种质量策略,分别是应用一标多测(SSDMC)和一法多用法。最后,本文介绍了一系列针对中药分析方法的改进。

The main constituents of a typical medicinal herb, Polygonum multiflorum (Heshouwu in Chinese), that induces idiosyncratic liver injury remain unclear. Our previous work has shown that cotreatment with a nontoxic dose of lipopolysaccharide (LPS) and therapeutic dose of Heshouwu can induce liver injury in rats, whereas the solo treatment cannot induce observable injury. In the present work, using the constituent “knock-out” and “knock-in” strategy, we found that the ethyl acetate (EA) extract of Heshouwu displayed comparable idiosyncratic hepatotoxicity to the whole extract in LPS-treated rats. Results indicated a significant elevation of plasma alanine aminotransferase, aspartate aminotransferase, and liver histologic changes, whereas other separated fractions failed to induce liver injury. The mixture of EA extract with other separated fractions induced comparable idiosyncratic hepatotoxicity to the whole extract in LPS-treated rats. Chemical analysis further revealed that 2,3,5,4'-tetrahydroxy trans-stilbene-2-O-β-glucoside (trans-SG) and its cis-isomer were the two major compounds in EA extract. Furthermore, the isolated cis-, and not its trans-isomer, displayed comparable idiosyncratic hepatotoxicity to EA extract in LPS-treated rats. Higher contents of cis-SG were detected in Heshouwu liquor or preparations from actual liver intoxication patients associated with Heshouwu compared with general collected samples. In addition, plasma metabolomics analysis showed that cis-SG-disturbing enriched pathways remarkably differed from trans-SG ones in LPS-treated rats. All these results suggested that cis-SG was closely associated with the idiosyncratic hepatotoxicity of Heshouwu. Considering that the cis-trans isomerization of trans-SG was mediated by ultraviolet light or sunlight, our findings serve as reference for controlling photoisomerization in drug discovery and for the clinical use of Heshouwu and stilbene-related medications.
