Background:Azadirachta indica, an evergreen tree, is used by several folkloric practitioners to treat peptic ulcers in India. The present study was carried out to evaluate the antiulcer activity of the aqueous extract (AE) of the leaves of A. indica in Wistar rats. Methods: Gastric ulcerations were induced by pyloric ligation, aspirin, and cold restraint stress. AE was used in doses of 150, 300, and 600 mg/kg body weight per os. Distilled water served as the control and ranitidine 20 mg/kg body weight intraperitoneal as the reference standard. The ulcer index (UI) and percentage inhibition (PI) values were determined in each model. The volume of gastric contents, free acidity, total acidity, and pH were measured in the pyloric ligation-induced ulcer model. Results: AE showed a dose-dependent and significant (p < 0.05) decrease in the UI and an increase in the PI in all models employed compared to the control group. AE caused a dose-dependent decline in the gastric content volume, free acidity, and total acidity. Conclusion: The leaves of A. indica possess significant antiulcer activity and act via multiple mechanisms.
背景:印楝是一种常青树,在印度被一些民间从业者用来治疗消化性溃疡。本研究旨在评价印楝叶水提物(AE)对Wistar大鼠的抗溃疡活性。方法:采用幽门结扎、阿斯匹林、冷约束应激诱导胃溃疡。AE的剂量分别为150、300和600 mg/kg体重。以蒸馏水为对照,雷尼替丁20 mg/kg体重腹腔注射为参比标准。测定各模型的溃疡指数(UI)和百分比抑制(PI)值。测定幽门结扎性溃疡模型胃内容物体积、游离酸度、总酸度及pH值。结果:与对照组相比,AE在所有模型中均呈剂量依赖性,显著降低UI (p < 0.05),增加PI (p < 0.05)。AE引起胃内容物体积、游离酸度和总酸度呈剂量依赖性下降。结论:印楝叶具有明显的抗溃疡活性,其作用机制多种多样。

Background/Aims: Vitiligo is a common disorder of depigmented skin. Traditional Chinese medicine (TCM) has been proved to be effective for the treatment of vitiligo, but the standard differential syndromes and effective formulas and herbs are still controversial. The aim of this study is to analyze the principles of differentiation and prescription in treating vitiligo in TCM based on a large-scale literature investigation. Methods: Articles about vitiligo treatment using TCM were searched in three databases, including China National Knowledge Infrastructure (1979-2014), China Science Periodical Database (1990-2014) and PubMed (1984-2014). The frequency of differential syndromes, formulas and herbs was analyzed using a metrological method and logistic multiple regression analysis. Results: Five syndromes account for the major differential categories in vitiligo: liver and kidney deficiency, Qi stagnation and blood stasis, liver depression and Qi stagnation, disharmony between Qi and blood, and blood conflicting with wind. The common formula prescriptions most frequently used were Tong-Qiao-Huo-Xue decoction, Xiao-Yao powder and Si-Wu decoction. The most frequently prescribed herbs were Angelica sinensis, Ligusticum wallichii, Tribulus terrestris, Polygonum multiflorum, Fructus psoraleae, Radix Paeoniae Rubra, Rehmannia glutinosa, Glossy Privet Fruit, Eclipta alba, Salvia miltiorrhiza, Liquorice, and Angelica dahurica, which shows that the treatment principles of vitiligo are tonifying the liver and kidney, activating blood and expelling wind. Conclusion: The most frequent syndromes of vitiligo are liver and kidney deficiency, Qi stagnation and blood stasis. Most TCM doctors prefer prescribing herbs with efficacy in tonifying the liver and kidney, activating blood and expelling wind in treating vitiligo.
背景/目的:白癜风是一种常见的脱色性皮肤疾病。中药治疗白癜风已被证实有效,但标准辨证及有效方剂和中药仍存在争议。本研究的目的是在大量文献调查的基础上,分析中医治疗白癜风的辨证方药原则。方法:检索中国国家知识基础设施(1979-2014)、中国科学期刊数据库(1990-2014)和PubMed(1984-2014) 3个数据库中有关中药治疗白癜风的文章。采用计量学方法和logistic多元回归分析辨证频次、方剂频次和中药频次。结果:肝肾虚证、气滞血瘀证、肝郁气滞证、气血不和证、血风不和证是白癜风的主要分型。常用方剂为通窍活血汤、逍遥散、四物汤。最常用的中药是当归、白芍、蒺藜、何首乌、补骨脂、芍药、地黄、女贞、黄花、丹参、甘草、白芷,说明白癜风的治疗原则是补肝补肾、活血祛风。结论:白癜风最常见的证候为肝肾虚证、气滞血瘀证。大多数中医医生在治疗白癜风时更喜欢选用补肝补肾、活血祛风的草药。

The Molecular Mechanism of Diastolic Heart Failure 舒张性心力衰竭的分子机制
Pub Date : 2015-10-15 DOI: 10.1159/000441223
Jialin Gu, F. Zhao, Yuqi Wang, Junjie Gao, Xiaolong Wang, Jingui Xue, Hua Zhou
Diastolic heart failure (DHF) is a group of clinical syndromes related to the performance of the pulmonary circulation and systemic circulation, with normal left ventricular (LV) systolic function. The pathophysiology of diastolic dysfunction includes delayed relaxation, impaired LV filling, and/or increased stiffness. These conditions result in impaired LV diastolic relaxation ability and a decrease in myocardial compliance. In recent years, studies on the mechanisms of DHF have focused on the renin-angiotensin-aldosterone system, inflammatory cytokines, oxidative stress, the process of myocardial calcium cycling, and associated proteins. The pathomechanism has been proven to be due to a deficiency in ATP, and Ca2+ cannot be reduced by sarcoplasmic reticulum calcium pump (SERCA2a), which leads to myocardial diastolic dysfunction. The correlation between the degradation process of ATP and its metabolites and DHF has also been studied in recent years. This paper summarizes the views on the above and analyzes the correlations between the molecular mechanisms.
舒张性心力衰竭(Diastolic heart failure, DHF)是一组与肺循环和体循环功能相关的临床综合征,左心室收缩功能正常。舒张功能障碍的病理生理包括舒张延迟、左室充盈受损和/或僵硬增加。这些情况导致左室舒张能力受损和心肌顺应性降低。近年来,对DHF机制的研究主要集中在肾素-血管紧张素-醛固酮系统、炎症细胞因子、氧化应激、心肌钙循环过程及相关蛋白等方面。病理机制已被证明是由于ATP缺乏,Ca2+不能通过肌浆网钙泵(SERCA2a)减少,从而导致心肌舒张功能障碍。近年来,ATP及其代谢物的降解过程与DHF之间的关系也得到了研究。本文综述了上述观点,并分析了分子机制之间的相关性。

Background: The use of transcranial laser or light-emitting diode (LED) therapy in the treatment of different neurological diseases is attracting increasing attention. The main goal of this study was to investigate different kinds of scientifically and commercially available laser (yellow, red, and infrared) and LED stimulation systems for the first time using a chick embryo model under a fixed human cadaver (scalp and/or skull) and without this anatomical preparation. Methods: In the present study, the extra-embryonic vasculature of a 1-week-old chick embryo chorioallantoic membrane (CAM) was investigated. For stimulation, four different systems were used (infrared LED and yellow, red, and infrared laser). Four measurement periods were compared: before stimulation, immediately after stimulation onset, immediately after the 10-min stimulation was turned off, and 6 min after stimulation had ended. Special image processing programs developed at the Beijing University of Science and Technology were used for data analysis. Results: The different kinds of laser induced different effects, e.g. the direct stimulation with yellow laser led to initial vasoconstriction (-17%), whereas yellow laser stimulation through a human skull resulted in an increase in blood volume. These effects could only be observed after mathematical processing of the images. Conclusion: After intensive basic research (e.g. CAM model), transcranial laser stimulation may open up new therapies for lifestyle-related diseases such as stroke, dementia, Alzheimer's or possibly Parkinson's disease.
背景:利用经颅激光或发光二极管(LED)治疗不同的神经系统疾病越来越受到重视。本研究的主要目标是首次使用鸡胚胎模型在固定的人类尸体(头皮和/或头骨)下,在没有这种解剖准备的情况下,研究不同种类的科学和商业上可用的激光(黄色,红色和红外)和LED刺激系统。方法:对1周龄鸡胚绒毛膜-尿囊膜(CAM)的胚外血管系统进行研究。对于刺激,使用了四种不同的系统(红外LED和黄色、红色和红外激光)。比较了刺激前、刺激开始后、刺激结束后10分钟、刺激结束后6分钟四个时间段的测量结果。使用北京科技大学开发的特殊图像处理程序进行数据分析。结果:不同类型的激光诱导的效果不同,如黄色激光直接刺激可引起初始血管收缩(-17%),而黄色激光通过颅骨刺激可引起血容量增加。这些效果只有在对图像进行数学处理后才能观察到。结论:经过深入的基础研究(如CAM模型),经颅激光刺激可能为中风、痴呆、阿尔茨海默病或可能的帕金森病等与生活方式相关的疾病开辟新的治疗方法。

Background/Aim: The mechanisms and processes of amyloid beta (Aβ)1-42/Aβ1-40 degeneration and deposition of neuron damage are still not clear. The long noncoding RNA (lncRNA) is one of the members of the noncoding RNA family. In this study, we aimed to investigate whether Aβ1-42 inhibited SH-SY5Y cells in vitro through modulating Meg3 lncRNA. Methods: The Alzheimer's disease (AD) senile plaque cell model was generated using synthetic Aβ1-42-treated SH-SY5Y cells. MTT assays were used to determine the proliferation of SH-SY5Y cells. Quantitative (q)RT-PCR and Western blot analyses were used to test the expression levels of mRNA and protein. Northern blot analysis was used to confirm Meg3 lncRNA expression. Results: The MTT assays showed that exogenous Aβ1-42 suppressed SH-SY5Y cells. The qRT-PCR and Western blot analyses revealed that the expression of p53 mRNA and protein was significantly increased in the AD model group, with a marked decrease in MDM2 and Ki-67 expression on day 7. Moreover, the qRT-PCR and Northern blot analyses confirmed that exogenous Aβ1-42 promoted the expression of Meg3 lncRNA. There was a downregulation of Meg3 lncRNA expression in SH-SY5Y cells by siRNA, which could promote of the ability of MDM2 to degrade p53 protein on the ubiquitin pathway and delay SH-SY5Y apoptosis. Conclusion: Meg3 lncRNA is implicated as an important factor in the formation of mature Aβ peptides.
背景/目的:淀粉样蛋白β (Aβ)1-42/Aβ1-40变性和沉积神经元损伤的机制和过程尚不清楚。长链非编码RNA (lncRNA)是非编码RNA家族的成员之一。在本研究中,我们旨在研究Aβ1-42是否通过调节Meg3 lncRNA在体外抑制SH-SY5Y细胞。方法:采用人工合成a β1-42处理的SH-SY5Y细胞制备老年痴呆症(AD)老年斑细胞模型。MTT法检测SH-SY5Y细胞的增殖情况。采用定量(q)RT-PCR和Western blot检测mRNA和蛋白的表达水平。Northern blot分析证实Meg3 lncRNA表达。结果:MTT实验显示外源性Aβ1-42对SH-SY5Y细胞有抑制作用。qRT-PCR和Western blot分析显示,AD模型组p53 mRNA和蛋白表达明显升高,第7天MDM2和Ki-67表达明显降低。此外,qRT-PCR和Northern blot分析证实外源Aβ1-42促进Meg3 lncRNA的表达。siRNA可下调SH-SY5Y细胞中Meg3 lncRNA的表达,从而促进MDM2在泛素通路上降解p53蛋白的能力,延缓SH-SY5Y细胞凋亡。结论:Meg3 lncRNA在成熟Aβ肽的形成中起重要作用。

Epigenetic Modification and Its Role in Alzheimer's Disease 表观遗传修饰及其在阿尔茨海默病中的作用
Pub Date : 2015-09-12 DOI: 10.1159/000437329

Alzheimer's disease (AD) is the most common neurodegenerative disease, and its mechanisms have not been clearly elucidated. A large percentage (more than 95%) of cases are late-onset AD without familial traits. Although some genes have been implicated in the pathogenesis and the risk of developing sporadic AD, they only account for the minority of late-onset AD. Recently, accumulating data have suggested a potential role for epigenetic mechanisms in neurodegenerative processes leading to dementia. Alterations in the epigenetic machinery cause aberrant DNA methylation and histone acetylation. Therefore, these changes trigger alterations on the transcriptional level of genes involved in the pathogenesis of AD. In this review, we summarize recent advances in research on AD caused by common epigenetic modification and the potential treatment strategies targeting the epigenetic machinery.
阿尔茨海默病(AD)是最常见的神经退行性疾病,其发病机制尚未明确。很大比例(超过95%)的病例为无家族性特征的晚发性AD。虽然一些基因与散发性阿尔茨海默病的发病机制和发病风险有关,但它们只占晚发性阿尔茨海默病的少数。最近,越来越多的数据表明,表观遗传机制在导致痴呆的神经退行性过程中可能起作用。表观遗传机制的改变导致异常的DNA甲基化和组蛋白乙酰化。因此,这些变化触发了与AD发病机制相关的基因转录水平的改变。本文综述了近年来常见表观遗传修饰引起的阿尔茨海默病的研究进展以及针对表观遗传机制的潜在治疗策略。

Integrative medicine, including traditional Chinese medicine (TCM), is a new concept in clinical practice for the treatment of neurodegenerative and most chronic diseases. However, integrative consensus or a guideline for the management of patients with Parkinson's disease (PD) is still lacking. The aim of this paper is to provide a review of experiences in clinical practice from Chinese neurologists and physicians (including TCM doctors) in Shanghai, China, and try to provide a clinical guideline for the treatment of the complex and progressive disease of PD with integrative medicine. We included the following treatments: common Western medication, surgery, TCM decoction and patent medicines, acupuncture and Tui na, Yoga, Tai chi chuan, hyperbaric oxygenation, rehabilitation, and other complementary and alternative medicines for the integrative management of the disease. Neurologists and physicians in Shanghai, China, and all over the world should pay attention to integrative medicine, which may be a good choice of treatment for PD.
包括中医在内的中西医结合是临床治疗神经退行性疾病和大多数慢性疾病的一个新概念。然而,对于帕金森病(PD)患者的治疗,目前仍缺乏统一的共识或指南。本文旨在总结中国上海神经科医师(包括中医医师)的临床实践经验,试图为中西医结合治疗复杂进行性帕金森病提供临床指导。治疗方法包括:西药、手术、中药汤剂、中成药、针灸推拿、瑜伽、太极拳、高压氧、康复等辅助和替代药物,综合治疗。中国上海乃至世界各地的神经科医生和医生都应该重视中西医结合,这可能是治疗PD的一个很好的选择。
