    实验和临床肝纤维化都留下了代谢足迹,可以使用代谢组学方法来发现和定义。代谢组学将模式识别算法与分析化学相结合,特别是,1H和13C核磁共振波谱(NMR),气相色谱-质谱(GC-MS)和各种液相色谱-质谱(LC-MS)平台。通过这些方法中的每一种对肝纤维化的分析分别进行审查。令人惊讶的是,这三组中的每一组内的研究之间以及组间的研究之间几乎没有共识.通过NMR确定的代谢组学足迹(研究之间的两次或更多次命中)包括乳酸升高,醋酸盐,胆碱,3-羟基丁酸酯,葡萄糖,组氨酸,蛋氨酸,谷氨酰胺,苯丙氨酸,酪氨酸和柠檬酸盐。对于GC-MS,琥珀酸盐,富马酸盐,苹果酸,抗坏血酸,谷氨酸,甘氨酸,丝氨酸和,与NMR一致,谷氨酰胺,苯丙氨酸,描绘了酪氨酸和柠檬酸盐。对于LC-MS,只有β-胞嘧啶酸,色氨酸,酰基肉碱,对甲酚,缬氨酸和,与NMR一致,磷酸胆碱被鉴定。关于谷氨酰胺,肝纤维化的代谢组学足迹上调,苯丙氨酸,酪氨酸,柠檬酸盐和磷酸胆碱。几位研究人员采用中药(TCM)治疗来逆转实验性肝纤维化,并对可能具有纤维化活性的化学成分进行了评论。有人提出,使用这些中药成分的分子对接程序可能会导致肝纤维化的新疗法,影响全球至少二十分之一的人。目前还没有药物治疗。这篇深入的综述总结了代谢组学的相关文献及其在解决肝纤维化临床问题中的意义,肝硬化及其后遗症。
    Both experimental and clinical liver fibrosis leave a metabolic footprint that can be uncovered and defined using metabolomic approaches. Metabolomics combines pattern recognition algorithms with analytical chemistry, in particular, 1H and 13C nuclear magnetic resonance spectroscopy (NMR), gas chromatography-mass spectrometry (GC-MS) and various liquid chromatography-mass spectrometry (LC-MS) platforms. The analysis of liver fibrosis by each of these methodologies is reviewed separately. Surprisingly, there was little general agreement between studies within each of these three groups and also between groups. The metabolomic footprint determined by NMR (two or more hits between studies) comprised elevated lactate, acetate, choline, 3-hydroxybutyrate, glucose, histidine, methionine, glutamine, phenylalanine, tyrosine and citrate. For GC-MS, succinate, fumarate, malate, ascorbate, glutamate, glycine, serine and, in agreement with NMR, glutamine, phenylalanine, tyrosine and citrate were delineated. For LC-MS, only β-muricholic acid, tryptophan, acylcarnitine, p-cresol, valine and, in agreement with NMR, phosphocholine were identified. The metabolomic footprint of liver fibrosis was upregulated as regards glutamine, phenylalanine, tyrosine, citrate and phosphocholine. Several investigators employed traditional Chinese medicine (TCM) treatments to reverse experimental liver fibrosis, and a commentary is given on the chemical constituents that may possess fibrolytic activity. It is proposed that molecular docking procedures using these TCM constituents may lead to novel therapies for liver fibrosis affecting at least one-in-twenty persons globally, for which there is currently no pharmaceutical cure. This in-depth review summarizes the relevant literature on metabolomics and its implications in addressing the clinical problem of liver fibrosis, cirrhosis and its sequelae.

    金丝桃豆N.Robson,一种常年直立的草本植物,主要居住在温带地区。该物种已用于治疗各种炎症相关疾病。从H.beanii的地上部分分离出一种新的xanthone3,7-二羟基-1,6-二甲氧基xanthone(1)和23种已知的xanthone(2-24)。新化合物的结构是基于高分辨率电喷雾电离质谱(HR-ESIMS)确定的,核磁共振(NMR),红外光谱(IR),紫外分光光度法(UV)光谱数据。通过测量对LPS刺激的RAW264.7巨噬细胞中一氧化氮(NO)产生的抑制作用来评估所有分离物的抗炎作用。化合物3,4-二羟基-2-甲氧基黄吨酮(15),1,3,5,6-四羟基氧杂酮(19),和1,3,6,7-四羟基黄吨酮(22)在10μM的浓度下表现出明显的抗炎作用,与阳性对照槲皮素相比具有更高的效力。此外,化合物15、19和22降低了诱导型NO合酶(iNOS),肿瘤坏死因子α(TNF-α),白细胞介素-1β(IL-1β),LPS刺激的RAW264.7巨噬细胞中IL-6和环氧合酶2(COX-2)mRNA的表达,表明这些化合物可以在转录水平上减轻上述分子的合成,暂时证实他们的抗炎功效。
    Hypericum beanii N. Robson, a perennial upright herb, predominantly inhabits temperate regions. This species has been utilized for the treatment of various inflammation-related diseases. One new xanthone 3,7-dihydroxy-1,6-dimethoxyxanthone (1) and twenty-three known xanthones (2-24) were isolated from the aerial parts of H. beanii. The structure of the new compound was determined based on high-resolution electrospray ionization mass spectroscopy (HR-ESIMS), nuclear magnetic resonance (NMR), Infrared Spectroscopy (IR), ultraviolet spectrophotometry (UV) spectroscopic data. The anti-inflammatory effects of all the isolates were assessed by measuring the inhibitory effect on nitric oxide (NO) production in LPS-stimulated RAW 264.7 macrophages. Compounds 3,4-dihydroxy-2-methoxyxanthone (15), 1,3,5,6-tetrahydroxyxanthone (19), and 1,3,6,7-tetrahydroxyxanthone (22) exhibited significant anti-inflammatory effects at a concentration of 10 μM with higher potency compared to the positive control quercetin. Furthermore, compounds 15, 19, and 22 reduced inducible NO synthase (iNOS), tumor necrosis factor alpha (TNF-α), interleukin-1β (IL-1β), IL-6, and cyclooxygenase 2 (COX-2) mRNA expression in the LPS-stimulated RAW 264.7 macrophages, suggesting that these compounds may mitigate the synthesis of the aforementioned molecules at the transcriptional level, provisionally confirming their anti-inflammatory efficacy.

    信神信神Kuwayama(D.柑橘)是柑橘产业的主要害虫之一,传播柑橘黄龙病。它对化学杀虫剂产生了抗药性。因此,寻找更绿色的害虫管理解决方案至关重要。这项研究的主要目的是评估来自四种桃金娘科植物的精油(EO)的驱虫和杀虫功效:Psidiumguajava(PG),尤加利(ER),桉树(ET),和Baeckeafrutescens(BF)对抗D.citri并分析其化学成分。进行GC-MS分析,结果表明,PG的EO,ER,ET,BF富含萜类化合物,酮,酯类,和酒精化合物。所有四种EO的驱避率均随暴露时间而降低,但在用四种EO以100%的浓度处理D.citri6h后,随着EO的浓度从80.50%增加到100.00%,并在暴露24小时后降低到67.71%至85.49%。在测试的EO化合物中,桉树脑的驱虫活性最强,24h驱避率为100%。接触毒性生物测定结果表明,所有EO对D.citri均具有杀虫毒性;若虫的LC50为36.47-93.15mL/L,对于成年人来说,60.72-111.00mL/L这些结果表明,当PG用作参考材料时,ER,ET,BFEO对D.citri有很强的生物活性,为进一步开发植物源性农用化学品提供了科学依据。
    Diaphorina citri Kuwayama (D. citri) is one of the major pests in the citrus industry, which spreads Citrus Huanglongbing disease. It has developed resistance to chemical insecticides. Therefore, searching for greener solutions for pest management is critically important. The main aim of this study was to evaluate the repellent and insecticidal efficacy of essential oils (EOs) from four species of Myrtaceae plants: Psidium guajava (PG), Eucalyptus robusta (ER), Eucalyptus tereticornis (ET), and Baeckea frutescens (BF) against D. citri and to analyze their chemical compositions. GC-MS analysis was performed, and the results indicated that the EOs of PG, ER, ET, and BF were rich in terpenoids, ketones, esters, and alcohol compounds. The repellent rate of all four EOs showed that it decreased with exposure time but increased with the concentration of EOs from 80.50% to 100.00% after treating D. citri for 6 h with four EOs at 100% concentration and decreased to 67.71% to 85.49% after 24 h of exposure. Among the compounds from the EOs tested, eucalyptol had the strongest repellent activity, with a 24 h repellency rate of 100%. The contact toxicity bioassay results showed that all EOs have insecticidal toxicity to D. citri; the LC50 for nymphs was 36.47-93.15 mL/L, and for adults, it was 60.72-111.00 mL/L. These results show that when PG is used as the reference material, the ER, ET, and BF EOs have strong biological activity against D. citri, which provides a scientific basis for the further development of plant-derived agrochemicals.

    巢湖201个表层沉积物和53个深层沉积物样品的主要化学成分,中国,进行了分析。由于巢湖表层沉积物(0-2cm深)是现代沉积物,本文主要研究了巢湖深层沉积物(深度50-100cm)。对CH3和CH4柱沉积物样品进行了粒度分析和磁化强度测定。报告了CH-1柱沉积物样品的年龄确定数据。还对巢湖流域的岩石及其化学组成特征进行了系统的研究。本研究结果表明,4个正化学风化指标和1个负化学风化指标适用于巢湖的研究。巢湖沉积物的平均CIA小于65,表明巢湖流域经历了弱化学风化,古气候寒冷干燥。CH3和CH4柱状沉积物中平均粒径和磁化强度的垂直变化反映了巢湖沉积物沉积过程中沉积环境和气候的变化。CH-1柱沉积物样品的年龄数据直接表明了中国东部小冰期(公元1380-1880年)巢湖深层沉积物的沉积。Th/U,Sc/Th,Rb/Sr,Na2O/K2O,巢湖沉积物的CaO/MgO和OC/N比值反映了巢湖流域古气候特征和烃源岩的化学成分。CIA的相关性,CIW,PIA,和CIX以及化学组成比可提供有关古气候和化学组成分布的信息。CIA,CIW,PIA,和CIX与Cd无关,Pb,As,Hg,或者P.相反,CIA,CIW,PIA,和CIX与Cr和N呈显着正相关。WIP与所选化学成分不一致。因此,化学风化指标与四种重金属和两种富营养化相关元素的相关性研究意义不大。内陆湖深层沉积物化学风化特征的研究应与湖盆地质特征的评价相结合,特别是湖盆岩石的化学成分分析。
    The main chemical compositions of 201 surface sediments and 53 deep sediment samples from Chaohu Lake, China, were analysed. Since the surface sediments (0-2 cm depth) in Chaohu Lake are modern sediments, this paper mainly focuses on the deep sediments (50-100 cm depth) in Chaohu Lake. Particle size analysis and magnetization determination of the CH3 and CH4 column sediment samples were carried out. The age determination data of the CH-1 column sediment samples are reported. A systematic study of the rocks and their chemical compositional characteristics in the Chaohu Lake Basin was also carried out. The results of this study show that four positive chemical weathering indicators and one negative chemical weathering indicator are applicable to the study of Chaohu Lake. The mean CIA of the Chaohu Lake sediments was less than 65, indicating that the Chaohu Lake Basin experienced weak chemical weathering and that the palaeoclimate was cold and dry. Vertical variations in the mean grain size and magnetization in the CH3 and CH4 columnar sediments reflect changes in the depositional environment and climate during deposition of the Chaohu Lake sediments. The age data from the CH-1 column sediment samples directly indicate deposition of the deep sediments in Chaohu Lake during the Little Ice Age in eastern China (AD 1380-1880). The Th/U, Sc/Th, Rb/Sr, Na2O/K2O, CaO/MgO and OC/N ratios of the Chaohu sediments reflect palaeoclimate characteristics and the chemical compositions of the source rocks in the Chaohu Lake basin. The correlations of the CIA, CIW, PIA, and CIX with the chemical compositional ratios provide information on the palaeoclimate and the distribution of the chemical compositions. The CIA, CIW, PIA, and CIX were not correlated with Cd, Pb, As, Hg, or P. In contrast, the CIA, CIW, PIA, and CIX were significantly positively correlated with Cr and N. The WIP was inconsistently correlated with the selected chemical components. Therefore, the study of the correlations of chemical weathering indicators with four heavy metals and two eutrophication-related elements is of little significance. The study of the chemical weathering characteristics of deep sediments of inland lakes should be combined with assessment of the geological characteristics of the lake basins, particularly the analysis of the chemical composition of the rocks in the lake basins.
