Objective

The unfavorable costs and effects of currently accessible antidepressant agents necessitate the development of more potent and safe alternatives, that will obviate the potential problems associated with the commercially available marketed ones. Phyllanthus emblica, widely known as emblic or amla, is utilized in traditional Asian medicine. In this study, the potential of Phyllanthus emblica's extract as an antidepressant drug was investigated.

Methods

The dried and pulverized powder of fruit was extracted in 70% ethanol. Rat model was used to assess the antidepressant effect of this extract and rats were treated with 800 ​mg/kg extract for 28 days. To assess the impact of the treatment, different behavioural tests like forced swimming test, tail suspension test, open field test, elevated plus maze, light dark box test, and coat state test were conducted.

Results

Following the administration of Phyllanthus emblica's extract, a significant decrease in immobility times was observed in the forced swimming test and tail suspension test (P ​< ​0.05). Similarly, the intake of glucose water was increased significantly (P ​< ​0.05) after Phyllanthus emblica's extract treatment. Additionally, in all behavioural tests associated with the open field test, elevated plus maze, and light dark box test, abnormal behavioural states were significantly restored (P ​< ​0.05) in the extract-treated group. Besides, in all behavioural tests, it has been observed that the standard drug also restored all the abnormal behavioural conditions. In silico docking revealed that compounds C_66 (stigmast-4-en-3-one) and C_43 (7-ketositosterol) exhibited the strongest binding affinity for MAO-A (−11.8 and −11.7 ​kJ/mol), surpassing the control drug Phenelzine (−6.7 ​kJ/mol), with distinct binding site residues. For hSERT, C_71 (Phyllanemblinin A, −11.4 ​kJ/mol) and C_66 (−10.8 ​kJ/mol) outperformed Fluoxetine (−8.9 ​kJ/mol), with Stigmast-4-en-3-one showing potential multi-target activity. ADME and toxicity prediction indicated low GI absorption for all candidates; C_43 showed the best drug-likeness and was predicted as non-toxic (class 6), while C_66 and C_71 were class 5, with additional nephrotoxicity and mutagenicity for C_71.

Conclusion

It can be inferred that the fruit extract of Phyllanthus emblica can efficiently reverse the disturbing psychological ailment towards a healthy status, which has the potential to be further developed into an alternative of currently accessible marketed antidepressant agents.
目的:鉴于目前可获得的抗抑郁药物成本低、效果差,有必要开发更有效、更安全的替代药物,以避免与市售药物相关的潜在问题。余甘子(Phyllanthus emblica),俗称余甘子,是亚洲传统医学中常用的一种植物。本研究探讨了余甘子提取物作为抗抑郁药物的潜力。方法用70%乙醇提取干燥、粉碎的果粉。采用大鼠模型评价该提取物的抗抑郁作用,大鼠给予800 mg/kg提取物28 d。为了评估处理的影响,进行了不同的行为试验,如强迫游泳试验、悬尾试验、露天试验、高架加迷宫试验、光暗箱试验和被毛状态试验。结果在强迫游泳试验和悬尾试验中,给药后大鼠静止时间显著减少(P < 0.05)。同样,经余甘子提取物处理后,葡萄糖水摄食量显著增加(P < 0.05)。此外,在与开场试验、高架加迷宫和光暗箱试验相关的所有行为测试中,提取物处理组的异常行为状态明显恢复(P < 0.05)。此外,在所有行为测试中,观察到标准药物也恢复了所有异常的行为状况。硅对接发现,化合物C_66(4-烯-3-one)和C_43(7-酮谷甾醇)对MAO-A的结合亲和力最强(- 11.8和- 11.7 kJ/mol),超过对照药物Phenelzine (- 6.7 kJ/mol),其结合位点残基明显。对于hSERT, C_71 (Phyllanemblinin A,−11.4 kJ/mol)和C_66(−10.8 kJ/mol)优于氟西汀(−8.9 kJ/mol),其中Stigmast-4-en-3-one表现出潜在的多靶点活性。ADME和毒性预测显示所有候选药物的胃肠道吸收较低;C_43表现出最好的药物相似性,预测为无毒(6级),而C_66和C_71为5级,对C_71具有额外的肾毒性和致突变性。结论余甘子提取物可有效逆转令人不安的心理疾病,使其恢复到健康状态,具有进一步开发成为市场上可获得的抗抑郁药物的替代方案的潜力。

Objective

This study aimed to systematically investigate the gastroprotective effects and underlying mechanisms of fresh Dendrobium officinale granules (FDG), a clinically convenient formulation of fresh Dendrobium officinale (D. officinale).

Methods

For the convenience of clinical use, fresh D. officinale was prepared into granules. The active ingredients of FDG were detected by HPLC. The gastroprotective efficacy of FDG was investigated in mice with alcoholic, indometacin, and reserpine gastric ulcer models, and in rats with acetic acid chronic gastric ulcers. The ulcer index, histopathology of gastric mucosa, and the levels of nitric oxide (NO), catalase (CAT), superoxide dismutase (SOD), and malondialdehyde (MDA) were measured. Network pharmacology method was used to predict the potential mechanism of FDG. Lastly, the expression levels of Keap1, Nrf2, and HO-1 were assessed by qRT-PCR and Western blot methods.

Results

HPLC result showed that the four active ingredients of FDG were vicenin-2, isoschaftoside, schaftoside, and 6-C-xylosyl-8-C-glucosylapigenin. FDG exerted significant effects against acute and chronic gastric ulcers in a dose-dependent manner. The network pharmacology analysis predicted the potential mechanism on oxidative stress and its related pathways. FDG remarkably increased SOD, NO, and CAT levels and lowered MDA levels in various gastric ulcer models, indicating it could enhance the antioxidant capacity to prevent gastric ulcers. FDG obviously down-regulated Keap1 expression and up-regulated Nrf2 and HO-1 expression.

Conclusion

This study proved the gastroprotective efficacy ​of fresh D. officinale, and its mechanism may be related to the antioxidation activity and the regulation of Keap1-Nrf2 signaling pathway.
目的系统研究新鲜铁皮石斛颗粒剂(鲜铁皮石斛颗粒剂)的胃保护作用及其机制。方法为方便临床使用,将新鲜officinale制成颗粒剂。用高效液相色谱法测定了FDG的有效成分。以酒精性、吲哚美辛、利血平胃溃疡模型小鼠和醋酸性慢性胃溃疡大鼠为实验对象,研究FDG的胃保护作用。测定大鼠溃疡指数、胃黏膜组织病理学及一氧化氮(NO)、过氧化氢酶(CAT)、超氧化物歧化酶(SOD)、丙二醛(MDA)水平。采用网络药理学方法预测FDG的潜在作用机制。最后,采用qRT-PCR和Western blot方法检测Keap1、Nrf2和HO-1的表达水平。结果hplc检测结果显示,黄芩苷的4种有效成分分别为维仙素-2、异麦草苷、麦草苷和6- c -木糖基-8- c -葡萄皂素。FDG对急性和慢性胃溃疡均有显著的剂量依赖性。网络药理学分析预测了氧化应激的潜在机制及其相关途径。FDG显著提高各种胃溃疡模型中SOD、NO、CAT水平,降低MDA水平,提示其可增强抗氧化能力,预防胃溃疡。FDG明显下调Keap1表达,上调Nrf2和HO-1表达。结论本研究证实了鲜铁皮鸡的胃保护作用,其机制可能与抗氧化活性及对Keap1-Nrf2信号通路的调节有关。

Additive manufacturing has recently demonstrated significant progress in healthcare. Six-dimensional (6D) printing is an emerging field that holds great promise through the rapid, layer-by-layer creation of complex objects capable of changing over time in response to external stimuli, resulting in dynamic and adaptable products. 6D printing represents a superimposition of 4D and 5D printing, combining the stimuli-responsiveness of 4D printing with the structural robustness of 5D printing. It uniquely enables autonomous, adaptive drug delivery systems by utilizing smart materials such as shape-memory alloys, responsive polymers, and hydrogels that react to environmental triggers. This review explores the evolution, mechanisms, significance, and innovations of 6D printing, which has made notable strides toward patient-centered medical approaches. Future developments in 6D printing may involve the use of material panels that adapt to stimuli varying over time under physiological conditions, offering new possibilities for advanced medical applications and solutions.

Drug-induced liver injury (DILI) is a severe adverse reaction caused by various drugs and their metabolites, with complex clinical manifestations, and severe cases may progress to acute liver failure (ALF) or even death. Currently, the pathogenesis of DILI has not been fully elucidated, and specific diagnostic indicators and effective therapeutic strategies are lacking, so it is crucial to deeply analyze its pathogenesis and develop precise intervention strategies. This review explores key pathogenic mechanisms in the development of DILI, with a focus on mitochondrial dysfunction, ferroptosis, immune responses and the gut-liver axis. It further systematically summarizes the clinical diagnostic approaches for DILI, including common diagnostic methods and potential biomarkers. Additionally, the review discusses therapeutic strategies for DILI, encompassing western medical treatments, ethnomedical treatments and non-pharmacological treatments. Although N-acetylcysteine (NAC) remains the FDA-approved standard treatment for acetaminophen (APAP) overdose, superior therapeutic options for DILI need to be explored urgently due to its therapeutic limitations and side effects. In the future, the prevention and treatment strategy of DILI will rely on deeper mechanistic investigations, development of novel biomarkers, and further exploration of multi-targeted traditional Chinese medicine (TCM) therapies.
药物性肝损伤(Drug-induced liver injury, DILI)是由多种药物及其代谢物引起的严重不良反应,临床表现复杂,严重者可发展为急性肝衰竭(acute liver failure, ALF),甚至死亡。目前DILI的发病机制尚未完全阐明,缺乏具体的诊断指标和有效的治疗策略,因此深入分析其发病机制,制定精准的干预策略至关重要。本文从线粒体功能障碍、铁下垂、免疫反应和肠-肝轴等方面探讨了DILI发展的主要致病机制。进一步系统总结了DILI的临床诊断方法,包括常见的诊断方法和潜在的生物标志物。此外,本文还讨论了DILI的治疗策略,包括西医治疗、民族医学治疗和非药物治疗。尽管n -乙酰半胱氨酸(NAC)仍然是fda批准的对乙酰氨基酚(APAP)过量的标准治疗方法,但由于其治疗局限性和副作用,迫切需要探索更好的DILI治疗方案。未来,DILI的防治策略将依赖于更深入的机制研究、新型生物标志物的开发以及多靶点中药治疗方法的进一步探索。

Objective

Alzheimer's disease (AD) is a common neurodegenerative disorder characterized by progressive memory decline and cognitive dysfunction. The specific pathogenesis of AD remains unclear. This study aimed to explore the crucial genes and therapeutic small-molecule compounds in AD via integrated bioinformatics analysis, molecular docking, and in vitro verification.

Methods

The gene dataset GSE122063, including 12 samples from patients with AD and 11 non-demented control samples, was downloaded from the Gene Expression Omnibus (GEO) database. The online tool GEO2R was used to analyze differentially expressed genes (DEGs). Functional enrichment analysis of the DEGs was performed using DAVID and ClueGo databases. A protein-protein interaction network was constructed using the STRING database and visualized in Cytoscape. Potential small-molecule compounds for AD therapy were screened using the Connectivity map database. The crucial genes in a rat model of AD were confirmed by RT-PCR. Molecular docking of the screened crucial genes and small-molecule compounds was further performed to identify potential therapeutic drugs for AD.

Results

A total of 1145 DEGs were identified, which were enriched in intracellular protein transport, cell cycle, establishment of protein localization to membrane, and so on. Eight hub genes, including RPS29, CREBBP, ANAPC10, ANAPC4, MAGOHB, TCEB2, RPL10A, and SEC61A1, were identified in the protein-protein interaction network. The MAPK signaling pathway was closely related to AD. Furthermore, increased expression of CREBBP was confirmed in the rat model of AD, and molecular docking revealed that CREBBP exhibited the strongest binding affinity with prochlorperazine.

Conclusion

CREBBP was identified as a crucial hub gene and might serve as a potential target for AD. Prochlorperazine, which exhibited strong binding to CREBBP, showed potential as a therapeutic drug in AD.

Aloe vera (Av) is revered in Ayurveda as the "wand of heaven" or "heaven's blessing" and precisely the "silent healer". This herbaceous plant belongs to Asphodelaceae family, previously classified as Liliaceae. In Traditional Chinese Medicine (TCM), Av is acknowledged for its abundant bioactive substances that have considerable therapeutic value. Therefore, the objective of this review is to analyze Av's bioactive compounds, highlighting its medicinal potential in drug development. An extensive literature review is performed utilizing databases such as PubMed, Web of Science, SpringerLink, and more until October 2024. The research investigates the bioactive compounds of Av and their in vivo, in vitro, and in silico effects on infections (bacterial, fungal, viral, and protozoan infections), along with their medicinal properties and significance in drug development. The most investigated active constituents of Av are aloin, emodin, acemannan, and aloesin. Av contains more than 100 potentially active components from six different classes: anthraquinone, chromone, phenylpropanoids, coumarins, phenylpyrone, and phytosterols, focusing on its anti-infective, anti-cancer, anti-diabetic, anti-oxidant, anti-inflammatory, immuno-modulatory activity and impact on neural diseases as well, based on peer-reviewed scientific data. By deepening the understanding of Av's medicinal value, this study may provide a reference for its future research and the development of new bioactive drug molecules from Av.
芦荟(Av)在阿育吠陀中被尊为“天堂的魔杖”或“天堂的祝福”,确切地说是“沉默的治疗师”。这种草本植物属于藤科,以前归类为百合科。在传统中医(TCM)中,Av因其丰富的生物活性物质而被公认具有相当的治疗价值。因此,本文对其生物活性成分进行分析,以突出其在药物开发中的应用潜力。在2024年10月之前,将利用PubMed、Web of Science、SpringerLink等数据库进行广泛的文献综述。本研究调查了病毒的生物活性化合物及其体内、体外和体内对感染(细菌、真菌、病毒和原生动物感染)的影响,以及它们的药用特性和在药物开发中的意义。研究最多的Av活性成分是芦荟素,大黄素,紫丁香聚糖和芦荟素。Av含有来自6个不同类别的100多种潜在活性成分:蒽醌、色素、苯丙素、香豆素、苯吡咯酮和植物甾醇,重点是其抗感染、抗癌、抗糖尿病、抗氧化、抗炎、免疫调节活性以及对神经疾病的影响,这是基于同行评审的科学数据。通过加深对Av药用价值的认识,本研究可为Av的进一步研究和从Av中开发新的生物活性药物分子提供参考。

Objective

Gastrointestinal complications (GITC) are a major cause of increased morbidity and mortality in stroke patients, significantly impairing recovery by triggering systemic inflammation and hindering brain healing. Raw Rhubarb (RR) is a commonly used traditional Chinese medicine with significant potential in treating GITC of ischemic stroke (IS). However, its therapeutic mechanisms remain largely unknown. This study aims to investigate the therapeutic effects and potential mechanisms of RR on GITC in IS through an integrated analysis of gut microbiota, metabolomics, and network pharmacology.

Methods

Male Sprague-Dawley rats were subjected to middle cerebral artery occlusion/reperfusion (MCAO/R) to induce IS. The rats were divided into six groups: sham, model, nimodipine-treated, and three different dose groups for RR. Neuroprotective efficacy was assessed using infarct size measurement, neurological scoring, and histopathological analysis. Gut microbiota composition was analyzed through 16S rRNA gene sequencing, while metabolomic profiling of brain and colon tissues was performed using UPLC-Q-Orbitrap HRMS/MS. Multivariate statistical methods were employed to identify the key metabolites and pathways affected by RR treatment. Correlation analysis was conducted to establish links between gut microbiota alterations and differential metabolites. Additionally, network pharmacology, molecular docking analysis, and Western blot assays were utilized to explore the molecular mechanisms underlying RR's treatment of GITC in IS.

Results

RR showed significant neuroprotective effects, reducing infarct volume, improving neurological scores, and restoring intestinal function compared to the model group. In addition, gut microbiota analysis revealed that RR administration reversed gut microbiota dysbiosis in MCAO/R rats by increasing the abundance of Bifidobacterium and Lactobacillus while decreasing the abundance of Escherichia-Shigella. Metabolomics analysis indicated that RR reversed the metabolic disturbances in MCAO/R rats by modulating arachidonic acid (AA) metabolism. Correlation analysis showed that AA and its metabolites, such as PGE2, were closely associated with Bifidobacterium and Lactobacillus. Combining metabolomics, network pharmacology, and molecular docking analysis suggested that RR might regulate AA metabolism through the PI3K/mTOR signaling pathway to treat GITC in IS. Finally, Western blot validation confirmed that RR modulates the PI3K/mTOR signaling pathway.

Conclusion

These findings indicate that RR holds significant promise as a therapeutic strategy for addressing GITC of IS. The protective effects mediated by RR are associated with the improvement of gut microbiota dysbiosis and metabolic disturbances.
胃肠道并发症(GITC)是卒中患者发病率和死亡率增加的主要原因,它通过引发全身性炎症和阻碍脑愈合而显著损害康复。生大黄(RR)是一种常用的中药,在治疗缺血性脑卒中(is)的GITC方面具有重要的潜力。然而,其治疗机制在很大程度上仍然未知。本研究旨在通过肠道微生物群、代谢组学和网络药理学的综合分析,探讨RR对IS中GITC的治疗作用及其潜在机制。方法采用大脑中动脉闭塞/再灌注法(MCAO/R)诱导小鼠IS。将大鼠分为假手术组、模型组、尼莫地平组和3个不同剂量的RR组。通过梗死面积测量、神经系统评分和组织病理学分析来评估神经保护效果。通过16S rRNA基因测序分析肠道菌群组成,使用UPLC-Q-Orbitrap HRMS/MS对脑和结肠组织进行代谢组学分析。采用多变量统计方法确定受RR治疗影响的关键代谢物和途径。进行了相关分析,以建立肠道微生物群改变与差异代谢物之间的联系。此外,我们还利用网络药理学、分子对接分析、Western blot等方法探讨了RR治疗IS中GITC的分子机制。结果与模型组比较,tsr具有明显的神经保护作用,可减少梗死面积,改善神经学评分,恢复肠道功能。此外,肠道菌群分析显示,RR通过增加双歧杆菌和乳酸杆菌的丰度而降低埃希氏杆菌-志贺氏菌的丰度,逆转了MCAO/R大鼠肠道菌群失调。代谢组学分析表明,RR通过调节花生四烯酸(AA)代谢逆转MCAO/R大鼠的代谢紊乱。相关性分析表明,AA及其代谢产物PGE2与双歧杆菌和乳杆菌密切相关。结合代谢组学、网络药理学、分子对接分析提示,RR可能通过PI3K/mTOR信号通路调控AA代谢,治疗IS中的GITC。最后,Western blot验证证实RR调节PI3K/mTOR信号通路。结论:这些发现表明,RR作为解决IS GITC的治疗策略具有重要的前景。RR介导的保护作用与改善肠道菌群失调和代谢紊乱有关。

Ageratum conyzoides L., Artocarpus gomezianus Wall. ex Trécul, Euphorbia hirta L., Plectranthus zeylanicus Benth., and Piper sarmentosum Roxb. have long been utilized in traditional medical practices, particularly across South and Southeast Asia. Despite their significant ethnopharmacological potential to treat various disorders, these plants remain underutilized in Sri Lanka. This review aims to evaluate the habit, propagation, ethnomedicinal uses, phytochemistry, and pharmacological properties of these five underutilized medicinal plants to promote their sustainable utilization in the herbal products industry of Sri Lanka. The plants were selected based on data from pharmacopeias and interviews with traditional medical practitioners. Scientific information on their ethnomedicinal uses, phytochemical compositions, and pharmacological properties was gathered from key scientific databases, including PubMed, Scopus, ScienceDirect, and Google Scholar, as well as web references and books. This information was analyzed to assess the factors contributing to their underutilization and their potential for novel herbal product development in Sri Lanka. All five plants possess a wide range of ethnomedicinal uses and are rich in bioactive compounds, including alkaloids, terpenoids, stilbenoids, and polyphenolic compounds. These bioactive compounds have been scientifically validated for their pharmacological properties, making these plants strong candidates for the development of novel pharmaceuticals and cosmeceuticals. However, their full potential remains largely untapped, primarily due to the lack of detailed phytochemical characterization and bioactive studies specific to Sri Lanka. Further preclinical and clinical research is needed to evaluate their therapeutic outcomes within the local context. The findings of this scoping review will guide future research and encourage broader use of these underutilized plants. Promoting their use will provide a sustainable alternative to the overexploitation of commonly used medicinal plants and support effective biodiversity conservation and resource management.
长尾叶柱,长尾叶柱。extracul, Euphorbia hirta L., Plectranthus zeylanicus Benth。Piper sarmentosum Roxb。长期以来一直用于传统医疗实践,特别是在南亚和东南亚。尽管这些植物具有治疗各种疾病的重大民族药理学潜力,但在斯里兰卡仍未得到充分利用。本综述旨在评估这五种未充分利用的药用植物的习性,繁殖,民族医药用途,植物化学和药理学特性,以促进其在斯里兰卡草药产品工业中的可持续利用。这些植物是根据药典的数据和对传统医生的采访选择的。从PubMed、Scopus、ScienceDirect和b谷歌Scholar等关键科学数据库以及网络参考文献和书籍中收集了有关其民族医学用途、植物化学成分和药理特性的科学信息。对这些信息进行了分析,以评估导致其未充分利用的因素及其在斯里兰卡开发新型草药产品的潜力。这五种植物都具有广泛的民族医药用途,并富含生物活性化合物,包括生物碱、萜类、苯乙烯类和多酚类化合物。这些生物活性化合物的药理特性已经过科学验证,使这些植物成为开发新药和药妆品的有力候选者。然而,它们的全部潜力在很大程度上仍未得到充分开发,这主要是由于缺乏详细的植物化学特性和斯里兰卡特有的生物活性研究。需要进一步的临床前和临床研究来评估它们在当地的治疗效果。这一范围审查的结果将指导未来的研究,并鼓励更广泛地利用这些未充分利用的植物。促进其利用将为常用药用植物的过度开发提供可持续的替代方案,并支持有效的生物多样性保护和资源管理。

Cellular senescence driven by mitochondrial dysfunction is a key contributor to ageing and related diseases. The decline in the quality and quantity of healthy mitochondria with ageing disrupts energy production, redox homeostasis, and intracellular signaling. Mitochondrial quality control (MQC) is a cellular self-repair mechanism that protects mitochondrial function and maintains a healthy mitochondrial network. Targeted regulation of MQC is expected to moderate the development of cellular senescence and related diseases. We explored the impact of mitochondrial function on cell fate at the molecular and organelle levels, analyzed the role of mitochondria-targeted interventions for delaying cellular senescence and ameliorating age-related diseases, and pointed out the idea of increasing the critical level of healthy mitochondria to cope with internal and external stressful stimuli and to improve the ability of self-repairing by exercising and protecting mitochondria in the long term.
