    背景:大多数严重失血性休克的重症通气患者会出现代谢性酸中毒,低蛋白血症,电解质不平衡,增加自由基的产生。Channastriata的白蛋白含量很高,一种有助于体内平衡的必需结合蛋白,当与辣木和姜黄合用时,它们作为强大的抗氧化剂。C.striata的管理,M.oleifera,和黄草提取物口服可能有益于患者的血液动力学问题,包括大量失血。
    方法:一名40岁的印尼妇女因第三个孩子分娩后10天胎盘滞留时间延长导致3级失血性休克导致意识下降,来到急诊科。她进行了紧急子宫切除术,并被送往重症监护病房,血红蛋白水平为4.2gr/dL,尽管在手术期间已经收到了两袋包装的红细胞,在重症监护室的第一天,她继续带着四个包。病人进行了通风,有血管加压药支持,白蛋白水平低,为2.1gr/dL。她的血液动力学特征很难稳定,持续的胃残留物和定期排尿量小于1cc/kg/小时,从而减缓呼吸机和血管加压药的断奶过程。口服补充纹状体梭菌,M.oleifera,并且在第二天给予黄草梭菌,每6小时分成三个剂量。第二次给药后,第三次给药后,胃残留物开始消退并消失。患者的病情在接下来的24小时内有所改善;她在第四天被拔管并出院。
    结论:这是描述纹状体梭菌作用的首例病例报告,M.oleifera,和黄草提取物用于因胎盘延长而患有严重失血性休克的患者。加速恢复显示了C.striata的可能好处,M.oleifera,和黄草提取物在稳定致癌压力中,中和自由基,并防止缺氧细胞的进一步损伤。
    BACKGROUND: Most of critically ventilated patients with severe hemorrhagic shock experience metabolic acidosis, hypoalbuminemia, electrolyte imbalance, and increased production of free radical. Channa striata has a high content of albumin, an essential binding protein that contributes to homeostasis, and when combined with Moringa oleifera and Curcuma xanthorrhiza, they act as powerful antioxidants. Administration of C. striata, M. oleifera, and C. xanthorrhiza extract orally may benefit patient with hemodynamic issues, including significant blood loss.
    METHODS: A 40-year-old Indonesian woman came to emergency department with decreased consciousness resulting from hemorrhagic shock grade 3 due to prolonged placenta retention for 10 days after delivery of her third child. She had an emergency hysterectomy and was sent to the intensive care unit with a hemoglobin level of 4.2 gr/dL, despite already receiving two bags of packed red blood cells during operation, and she continued with four more bags within her first day in the intensive care unit. The patient was ventilated, was supported by vasopressors, and had a low albumin level of 2.1 gr/dL. Her hemodynamic profile was difficult to stabilize, with persistent gastric residue and periodic urine output less than 1 cc/kg/hour, thereby slowing the ventilator and vasopressor weaning process. Oral supplementation of C. striata, M. oleifera, and C. xanthorrhiza was given in the second day divided in three doses every 6 hours. After the second dose, gastric residue started to subside and disappeared after the third dose. The patient\'s condition improved in the next 24 hours; she was extubated and discharged from the hospital in the fourth day.
    CONCLUSIONS: This is the first case report describing the effect of C. striata, M. oleifera, and C. xanthorrhiza extract in a patient with severe hemorrhagic shock due to a prolonged placenta. Accelerated recovery showed the possibility benefit of C. striata, M. oleifera, and C. xanthorrhiza extract in stabilizing oncotic pressure, neutralizing free radicals, and preventing further damage in hypoxic cells.

    我们介绍了一例69岁的男子,他进行了常规检查,偶然发现患有肾衰竭,最初未显露出来的病史和清淡的尿沉渣。在慢性姜黄补充和慢性抗生素治疗伴随腹泻的情况下,他被诊断为草酸盐肾病。我们的案例提供了一些关于草酸盐肾病的关键见解。首先,诊断需要高度的临床怀疑。除非病史中有明显的线索,例如Roux-en-Y胃旁路术或乙二醇中毒,否则临床上不常见。诊断可以通过组织病理学发现来证实,并通过血清草酸盐水平和24小时尿排泄来证实。第二,由于晶体的特性,病理学家通常会错过诊断,除非肾脏病理学家规定在偏振光下常规检查所有H&E切片.这必须在H&E上完成,因为其他污渍溶解了晶体。第三,常规穿刺活检中的一个草酸盐晶体被认为是病理性的,并可能以重要方式导致AKI或CKD。第四,在许多情况下可以在很大程度上减轻或预防继发性草藻病,尤其是医源性病例.这可以通过外科医生或胃肠病学家向患者提供草酸盐限制饮食或其他特定饮食措施的适当指导来实现。最后,这个案例凸显了病理学家和主治医师之间的合作和沟通所带来的成功。
    We present a case of a 69-year-old man who presented for routine check-up and was incidentally found to have kidney failure with an initially unrevealing history and bland urinary sediment. He was diagnosed with oxalate nephropathy in the setting of chronic turmeric supplementation and chronic antibiotic therapy with associated diarrhea. Our case provides several key insights into oxalate nephropathy. First, the diagnosis requires a high index of clinical suspicion. It is uncommonly suspected clinically unless there is an obvious clue in the history such as Roux-en-Y gastric bypass or ethylene glycol poisoning. Diagnosis can be confirmed by histopathologic findings and corroborated by serum levels of oxalate and 24-hour urinary excretion. Second, the diagnosis can often be missed by the pathologist because of the characteristics of the crystals unless the renal pathologist has made it a rule to examine routinely all H&E sections under polarized light. This must be done on H&E, as the other stains dissolve the crystals. Third, one oxalate crystal in a routine needle biopsy is considered pathologic and potentially contributing to the AKI or to the CKD in an important way. Fourth, secondary oxalosis can be largely mitigated or prevented in many cases, especially iatrogenic cases. This can come through the surgeon or the gastroenterologist providing proper instructions to patients on an oxalate-restricted diet or other specific dietary measures. Lastly, this case highlights the success that results from cooperation and communication between the pathologist and the treating physician.

    他克莫司是一种广泛用于预防移植后排斥反应的免疫抑制剂。体外研究表明,香料和他克莫司之间存在相互作用。我们介绍了一名年龄在70岁左右的肾移植患者,他接受了泼尼松治疗,霉酚酸酯和他克莫司。患者有移植前的饮食习惯,即食用姜黄香料的食物,咖喱和姜。以下方案平行实施,密切监测血浆他克莫司浓度:给予10克/天的姜黄4天,然后10克/天咖喱4天,然后10克/天生姜4天。在实施方案期间和之后没有观察到他克莫司血浆浓度的变化。姜黄的影响,咖喱和生姜对血浆他克莫司的体内浓度似乎可以忽略不计,尽管还需要进一步的研究。在饮食习惯涉及这些香料的患者中,共同决定测试香料消费的影响似乎是合理的。
    Tacrolimus is a widely used immunosuppressant for the prevention of rejection after transplantation. In vitro studies suggest that interactions exist between spices and tacrolimus. We present the case of a renal transplant patient aged around 70 years who was treated with prednisone, mycophenolate-mofetil and tacrolimus. The patient had a pre-transplant dietary habit of consuming foods spiced with turmeric, curry and ginger. The following protocol was implemented in parallel with close monitoring of plasma tacrolimus concentrations: administration of 10 g/day of turmeric for 4 days, then 10 g/day of curry for 4 days and then 10 g/day of ginger for 4 days. No change in tacrolimus plasma concentrations during and after the implementation of the protocol was observed. The impact of turmeric, curry and ginger on plasma tacrolimus concentrations seems negligible in vivo although further studies are needed. A shared decision to test the impact of spice consumption in a patient with dietary habits involving these spices seems reasonable.

    姜黄面临着真实性问题,这是为了降低成本而进行经济掺假的例子。我们使用碳14和HPLC分析作为补充方法来验证含有姜黄成分的商业膳食补充剂的“全天然”标签声明。姜黄素至姜黄素的高百分比值被用作暗示合成姜黄素存在的指标。然而,单独使用HPLC方法不能提供姜黄素天然来源的直接证据,而仅使用碳-14方法无法测试效力标签声明并确定哪些成分含有14C放射性碳。通过分析这两种方法的结果,姜黄素至姜黄素的百分比和%生物基碳之间的显著相关性(Pearson'sr=-0.875,p<0.001)表明合成姜黄素在很大程度上归因于确定的合成成分。在分析的14个样本中,只有4个支持真实的标签声明。这种正交试验策略显示了其对姜黄制品质量控制的潜力。
    Turmeric has faced authenticity issues as instances of economic-adulterations to reduce the cost. We used carbon-14 and HPLC analyses as complementary methods to verify \"all-natural\" label claims of commercial dietary supplements containing turmeric ingredients. A high percentage of curcumin-to-curcuminoids value was used as an indicator to imply the presence of synthetic curcumin. However, using the HPLC method alone did not provide direct evidence of curcuminoids\' natural origin, whereas using only the carbon-14 method cannot test for potency label claims and determine which constituent(s) contain 14C radiocarbon. By analyzing results from both methods, a significant correlation between the percentage of curcumin-to-curcuminoids and % biobased carbon (Pearson\'s r = -0.875, p < 0.001) indicated that synthetic curcumin was greatly attributed to determined synthetic ingredients. Only four out of the 14 samples analyzed supported authentic label claims. This orthogonal testing strategy showed its potential for the quality control of turmeric products.

    在食用含有姜黄的膳食补充剂后,意大利最近出现了几例急性非传染性胆汁淤积性肝炎。这项研究的目的是描述急性肝炎的托斯卡纳(意大利)病例,并通过进行系统评价将其与文献中发表的类似肝毒性病例进行比较。
    托斯卡纳急性肝炎病例的记录是从意大利植物警戒系统获得的。分析了每个自发报告,以收集患者的所有相关临床信息以及有关含姜黄的膳食补充剂的信息。此外,RUCAM和WHO-UMC系统均用于评估膳食补充剂的使用与急性肝炎之间的因果关系.在MEDLINE和Embase中进行了系统的文献综述,并包括了所有以英文发表的病例报告和病例系列。
    描述了截至2019年9月在托斯卡纳发生的7例急性肝炎病例。在所有情况下,肝毒性与姜黄素制剂具有高生物利用度和高剂量姜黄素/姜黄素相关。在大多数情况下观察到的阳性去激发也支持了因果关系。在通过系统审查确定的23起案件中,大多数患者同时接受至少一种其他药物治疗,其中16例患者出现阳性去激发.
    在控制和监管不佳的产品框架内,如膳食补充剂,对意大利郁金香致急性肝炎病例的评估和文献系统综述证实了郁金香与肝损伤之间的关联.
    Several cases of acute non-infectious cholestatic hepatitis recently appeared in Italy following consumption of Curcuma longa-containing dietary supplements. The aim of this research was to describe the Tuscan (Italy) cases of acute hepatitis and to compare them with similar cases of hepatotoxicity published in the literature by performing a systematic review.
    Records of Tuscan cases of acute hepatitis were obtained from the Italian Phytovigilance system. Each spontaneous report was analysed in order to collect all relevant clinical information of patients and information concerning the Curcuma longa-containing dietary supplement. Moreover, both the RUCAM and WHO-UMC systems were used to evaluate the causal relationship between the use of dietary supplement and acute hepatitis. A systematic literature review was performed in MEDLINE and Embase and all case-reports and case-series published in English were included.
    Seven cases of acute hepatitis occurring in Tuscany up to September 2019 are described. In all cases, hepatotoxicity was associated with Curcuma longa formulations with high bioavailability and high dosage of curcumin/curcuminoids. The causal relationship was also supported by the positive dechallenge observed in most cases. In the 23 cases identified through the systematic review, the majority of patients were concomitantly exposed to at least one other medication and 16 of them experienced a positive dechallenge.
    Within the frame of poorly controlled and regulated products, such as dietary supplements, the evaluation of Italian cases of Curcuma longa-induced acute hepatitis and the systematic review of literature confirmed the association between Curcuma longa and liver injury.

    他克莫司,也称为FK-506,是一种有效的免疫抑制剂,具有药物-药物和食物-药物相互作用的宿主。我们介绍了第一例姜黄和他克莫司之间可能的食物-药物相互作用,导致急性钙调磷酸酶抑制剂肾毒性。一名56岁的有原位肝移植史的男子从诊所到急诊科就诊,在肌酐水平升高为4.2mg/dL的情况下,水肿恶化。在当前演示之前,该患者最近接受了先前耐受的低剂量他克莫司方案,全血他克莫司水平在所需范围内.在患者的用药方案没有任何变化的情况下,再次住院当天的他克莫司水平升高至29.9ng/mL。在进一步提示时,患者发现最近在食物中摄入了高剂量的姜黄。他克莫司从患者的药物治疗方案中被拘留,他在第4天出院,客观证据表明肾功能改善。我们的报告建立在先前描述姜黄或其活性成分对他克莫司药代动力学影响的研究的基础上。对于他克莫司水平无法解释的患者,适当调和姜黄等草药可能是值得的。
    Tacrolimus, also known as FK-506, is a potent immunosuppressant agent with a host of drug-drug and food-drug interactions. We present the first case of a probable food-drug interaction between the herb turmeric and tacrolimus leading to acute calcineurin inhibitor nephrotoxicity. A 56-year-old man with a history of orthotopic liver transplantation presented to the emergency department from the clinic with worsening edema in the setting of an elevated creatinine level of 4.2 mg/dL. Before the current presentation, the patient had been recently discharged on a previously tolerated low-dose regimen of tacrolimus with a whole-blood tacrolimus level within the desired range. Tacrolimus level on the day of re-hospitalization was elevated to 29.9 ng/mL in the absence of any changes to the patient\'s medication regimen. On further prompting, the patient identified recent high-dose intake of turmeric with his food. Tacrolimus was held from the patient\'s medication regimen, and he was discharged on hospital day 4 with objective evidence of improving renal function. Our report builds on the previous studies that described the effects of turmeric or its active ingredient on the pharmacokinetics of tacrolimus. The appropriate reconciliation of herbal agents such as turmeric can be worthwhile in patients with unexplained changes in tacrolimus levels.

    要充分了解草药的化学多样性是具有挑战性的。在这项工作中,我们描述了一种新的方法,以全球概况和发现新的化合物从草药提取物使用多个中性损失/前体离子扫描结合亚结构识别和统计分析。以姜黄(姜黄的根茎)为例。该方法包括三个步骤:(i)多次中性损失/前体离子扫描以获得子结构信息;(ii)通过提取的离子电流和子结构识别来有针对性地识别新化合物;以及(iii)使用总离子电流和多变量统计分析来发现新结构的无针对性识别。使用这种方法,从姜黄中发现了846种萜姜黄素(萜烯结合的姜黄素),包括一些潜在的新化合物。此外,纯化了两种前所未有的化合物(果胶姜黄素X和Y),并通过NMR光谱鉴定了它们的结构。这项研究将质谱的应用扩展到草药中天然产物的全球分析,并可以帮助化学家从复杂的基质中快速发现新化合物。
    To fully understand the chemical diversity of an herbal medicine is challenging. In this work, we describe a new approach to globally profile and discover novel compounds from an herbal extract using multiple neutral loss/precursor ion scanning combined with substructure recognition and statistical analysis. Turmeric (the rhizomes of Curcuma longa L.) was used as an example. This approach consists of three steps: (i) multiple neutral loss/precursor ion scanning to obtain substructure information; (ii) targeted identification of new compounds by extracted ion current and substructure recognition; and (iii) untargeted identification using total ion current and multivariate statistical analysis to discover novel structures. Using this approach, 846 terpecurcumins (terpene-conjugated curcuminoids) were discovered from turmeric, including a number of potentially novel compounds. Furthermore, two unprecedented compounds (terpecurcumins X and Y) were purified, and their structures were identified by NMR spectroscopy. This study extended the application of mass spectrometry to global profiling of natural products in herbal medicines and could help chemists to rapidly discover novel compounds from a complex matrix.

    姜黄素,或者二铁酰基甲烷,从姜黄根茎中分离出的多酚分子,据报道,调节参与癌症和炎症过程的多个分子靶标。根据其泛抑制特性,在这里,我们表明姜黄素支架的简单化学修饰可以调节其生物选择性。特别是,姜黄素支架在C-1,C-8和/或C-8位置[C5(异戊烯基,5-8),C10(香叶基,9-12),和C15(法尼基,13,14)]以使这些分子对两个特定靶标比母体化合物更具选择性:组蛋白脱乙酰酶(HDAC)和微粒体前列腺素E2合酶-1(mPGES-1)。从计算机模拟和体外分析相结合,通过在8位进行适当取代,揭示了三种选择性抑制剂。化合物13相对于母体化合物具有改善的HDAC抑制活性和选择性,而5和9阻断mPGES-1酶。我们假设姜黄素的共价相互作用,5和9具有mPGES-1结合位点。
    Curcumin, or diferuloylmethane, a polyphenolic molecule isolated from the rhizome of Curcuma longa, is reported to modulate multiple molecular targets involved in cancer and inflammatory processes. On the basis of its pan-inhibitory characteristics, here we show that simple chemical modifications of the curcumin scaffold can regulate its biological selectivity. In particular, the curcumin scaffold was modified with three types of substituents at positions C-1, C-8, and/or C-8\' [C5 (isopentenyl, 5-8), C10 (geranyl, 9-12), and C15 (farnesyl, 13, 14)] in order to make these molecules more selective than the parent compound toward two specific targets: histone deacetylase (HDAC) and microsomal prostaglandin E2 synthase-1 (mPGES-1). From combined in silico and in vitro analyses, three selective inhibitors by proper substitution at position 8 were revealed. Compound 13 has improved HDAC inhibitory activity and selectivity with respect to the parent compound, while 5 and 9 block the mPGES-1 enzyme. We hypothesize about the covalent interaction of curcumin, 5, and 9 with the mPGES-1 binding site.

    姜黄素是姜黄粉的活性成分,一种传统药物中代代相传的天然香料。姜黄素的广谱抗氧化剂,抗癌,抗突变,和抗炎特性使其对药物化合物的开发特别感兴趣。由于姜黄素对许多无关膜蛋白的功能的各种影响,有人认为它影响双层本身的性质。然而,尚未尝试对姜黄素与膜的相互作用进行详细的原子级研究。固态NMR和差示扫描量热法实验的组合表明,姜黄素在低浓度下对膜结构有很强的影响。姜黄素以跨双层方向深入插入膜中,以类似于胆固醇的方式通过氢键结合到脂质的磷酸基团上而锚定。像胆固醇一样,姜黄素诱导膜中的分段排序。从NMR结果得出的有序参数分布的浓度依赖性分析表明,姜黄素在膜中形成了更高阶的寡聚结构,该结构跨越并可能使双层变薄。姜黄素促进高度弯曲的倒六方相的形成,这可能会影响细胞内的胞吐和膜融合过程。此处概述的实验显示了理解其他药物如辣椒素的作用的希望,其中药物诱导的膜结构改变具有很强的药理作用。
    Curcumin is the active ingredient of turmeric powder, a natural spice used for generations in traditional medicines. Curcumin\'s broad spectrum of antioxidant, anticarcinogenic, antimutagenic, and anti-inflammatory properties makes it particularly interesting for the development of pharmaceutical compounds. Because of curcumin\'s various effects on the function of numerous unrelated membrane proteins, it has been suggested that it affects the properties of the bilayer itself. However, a detailed atomic-level study of the interaction of curcumin with membranes has not been attempted. A combination of solid-state NMR and differential scanning calorimetry experiments shows curcumin has a strong effect on membrane structure at low concentrations. Curcumin inserts deep into the membrane in a transbilayer orientation, anchored by hydrogen bonding to the phosphate group of lipids in a manner analogous to cholesterol. Like cholesterol, curcumin induces segmental ordering in the membrane. Analysis of the concentration dependence of the order parameter profile derived from NMR results suggests curcumin forms higher order oligomeric structures in the membrane that span and likely thin the bilayer. Curcumin promotes the formation of the highly curved inverted hexagonal phase, which may influence exocytotic and membrane fusion processes within the cell. The experiments outlined here show promise for understanding the action of other drugs such as capsaicin in which drug-induced alterations of membrane structure have strong pharmacological effects.
