    BACKGROUND: Hodgsonia heteroclita has been known as an important traditionally consumed medicinal plant of North-East India known to have antidiabetic properties. This study aims to investigate the effects of the ethanolic fruit extract of Hodgsonia heteroclita against hyperglycemia and hyperlipidemia by using streptozotocin (STZ) treated diabetic mice.
    METHODS: The fruits of H. heteroclita were collected from the various parts of Kokrajhar district, Assam India (Geographic coordinates: 26°24\'3.85″ N 90°16\'22.30″ E). Basic morphological evaluations were carried out by the Botanical Survey of India, Eastern circle, Shillong, who also certified and identified the plant. Hexane, chloroform, and ethanolic extracts of the fruit of H. heteroclita were investigated for α-amylase inhibition assay as a rapid screening tool for examining anti-diabetic activity. The efficacy of ethanolic extract at a dose of 100, 200, and 300 mg/kg body weight was tested for 21 days in STZ-induced diabetic mice. The body weight, fasting plasma glucose and serum lipids, and hepatic glycogen levels were measured in experimental animals to examine the antihyperglycemic and antihyperlipidemic efficacy of the extract. Both HPTLC and LC-MS analysis was performed to examine the phyotochemicals present in the ethanolic extract of H. heteroclita.
    RESULTS: It has been observed that treatment with the ethanolic extract dose-dependently reduced the plasma glucose levels, total cholesterol, low density lipoprotein-cholesterol, very low-density lipoprotein-cholesterol, triglyceride, and increased the body weight, liver glycogens and high-density lipoprotein-cholesterol in STZ treated diabetic mice. HPTLC demonstrated the presence of triterpene compounds and LC-MS analysis revealed the presence Cucurbitacin I, Cucurbitacin E, and Kuguacin G as the triterpene phytoconstituents.
    CONCLUSIONS: The present study demonstrated that ethanolic fruit extract of H. heteroclita improved both glycemic and lipid parameters in mice model of diabetes.

    非酒精性脂肪性肝病(NAFLD)的流行及其代谢影响引起了严重的公共卫生问题。我们假设斋月禁食模型(RFM),这包括从黎明到黄昏禁食一个月,可以提供潜在的治疗益处并减轻NAFLD。因此,我们旨在用肥胖雄性大鼠验证这一假设.
    将大鼠分为两组(每组n=24),并给予标准(S)或高脂饮食(HFD)12周。在研究期间的最后四周,以S和HFD喂养的大鼠均被细分为八组,以评估有/无训练(T)或葡萄糖给药(G)的RFM对脂质分布的影响,肝酶,和肝脏结构(n=6/组)。
    HFD+RFM组的最终体重明显低于HFDC组。血清胆固醇,低密度脂蛋白,甘油三酯水平在HFD+RFM中显著降低,HFD+RFM+T,而HFD+RFM+G组高于HFDC组。与HFDC组相比,所有组的血清高密度脂蛋白水平均有改善.此外,与HFD喂养组相比,接受RFM的HFD组的天冬氨酸转氨酶和丙氨酸转氨酶的血清水平降低。此外,与HFD喂养的大鼠相比,接受RFM的大鼠的肝脏组织学有所改善,表现出宏观和微观脂肪液滴的积累。
    RFM可以诱导积极的代谢变化并改善与NAFLD相关的改变,包括体重增加,血脂谱,肝酶,和肝脏脂肪变性.
    UNASSIGNED: The epidemic of nonalcoholic fatty liver disease (NAFLD) and its metabolic effects present a serious public health concern. We hypothesized that the Ramadan fasting model (RFM), which involves fasting from dawn to dusk for a month, could provide potential therapeutic benefits and mitigate NAFLD. Accordingly, we aimed to validate this hypothesis using obese male rats.
    UNASSIGNED: Rats were split into two groups (n = 24 per group), and they were given either a standard (S) or high-fat diet (HFD) for 12 weeks. During the last four weeks of the study period, both S- and HFD-fed rats were subdivided into eight groups to assess the effect of RFM with/without training (T) or glucose administration (G) on the lipid profile, liver enzymes, and liver structure (n = 6/group).
    UNASSIGNED: The HFD+RFM group exhibited a significantly lower final body weight than that in the HFDC group. Serum cholesterol, low-density lipoprotein, and triglyceride levels were significantly lower in the HFD+RFM, HFD+RFM+T, and HFD+RFM+G groups than those in the HFDC group. Compared with the HFDC group, all groups had improved serum high-density lipoprotein levels. Furthermore, HFD groups subjected to RFM had reduced serum levels of aspartate transaminase and alanine transaminase compared with those of the HFD-fed group. Moreover, the liver histology improved in rats subjected to RFM compared with that of HFD-fed rats, which exhibited macro- and micro-fat droplet accumulation.
    UNASSIGNED: RFM can induce positive metabolic changes and improve alterations associated with NAFLD, including weight gain, lipid profile, liver enzymes, and hepatic steatosis.

    洛伐他汀(Lov)是一种降脂药,由于广泛的首过代谢和差的溶解度,具有5%的生物利用度(BA)。为了增强溶出度和体内效果,开发了Lov固体自微乳化给药系统(SMEDDS)和液体固体给药系统,并对其进行了评估,以选择较优的给药系统。在油中测定溶解度,表面活性剂,和助表面活性剂。构建了三元相图,并选择了显示最大乳液区的三元相图。体外溶出度,DSC,SEM和PXRD研究用于表征开发的制剂。在wistar大鼠中对最佳制剂进行体内研究。基于溶解度,CapmulPG8和CapmulMCM是首选油,Labrasol和TranscutolP作为表面活性剂和助表面活性剂。这里,SyloidXDP载体表现出更好的吸附能力,因此用于最佳固体SMEDDS(SX)和液体固体(LS)制剂。与纯药物相比,溶解研究结果显示释放显著改善。DSC,SEM,和PXRD结果表明最佳制剂中药物结晶度的损失。在药代动力学(PK)研究中,SX和LS显示AUC改善2.57和1.43倍,与粗悬浮液(CS)相比。在药效学(PD)研究中,TritonX-100诱导高脂血症。CS和LS治疗在4小时显示高脂血症水平下降。但是,SX治疗组在2h时显示出早期发作的下降。与CS和LS相比,抗高脂血症的持续时间至少超过12h.这项研究证实了SX在PK和PD效应方面优于LS。
    Lovastatin (Lov) is a lipid-lowering agent, with 5% bioavailability (BA) due to extensive first pass metabolism and poor solubility. To enhance dissolution and in vivo effects, Lov solid self microemulsifying drug delivery system (SMEDDS) and liquisolid systems were developed and evaluated to select superior one. Solubilities were determined in oils, surfactants, and cosurfactants. Ternary phase diagrams were constructed and selected the one which showed maximum emulsion zone. In vitro dissolution, DSC, SEM and PXRD studies were used to characterize the developed formulations. In vivo studies were conducted on optimal formulations in wistar rats. Based on solubilities, Capmul PG8 and Capmul MCM were preferred as oils, Labrasol and Transcutol P as surfactant and cosurfactant. Here, Syloid XDP carrier showed better adsorption capacity among others, hence was used in optimal solid SMEDDS (SX) and liquisolid (LS) formulations. Dissolution study results showed significant improvement in release when compared to pure drug. DSC, SEM, and PXRD results indicated the loss of drug crystallinity in optimal formulations. In pharmacokinetic (PK) study, SX and LS showed 2.57 and 1.43 fold improvements in AUC, when compared to that of coarse suspension (CS). In pharmacodynamic (PD) study, hyperlipidemia was induced by Triton X-100. CS and LS treatments showed a decline in hyperlipidemic levels at 4 h. But, SX-treated group showed early onset of decline at 2 h. Further, the duration of anti-hyperlipidemia was at least 12 h extra when compared to CS and LS. This study confirmed the superiority of SX over LS in PK and PD effects.

    辛伐他汀是一种成熟的抗高脂血症药物,很少有研究表明其在缓解氧化应激中的作用。然而,关于辛伐他汀与抗氧化酶的分子结合/相互作用的系统研究,以及在体外和体内的确证性研究尚未完成.我们研究了辛伐他汀与多种抗氧化酶的分子结合,并评估了辛伐他汀在体外和体内治疗后的水平。本研究首次通过分子对接分析显示辛伐他汀与过氧化氢酶的分子结合。此外,尚未研究辛伐他汀在脂多糖(LPS)诱导的HepG2细胞氧化应激中的抗氧化作用。我们发现辛伐他汀通过增加抗氧化酶的水平有效减轻LPS诱导的HepG2细胞和高脂饮食(HFD)喂养的高脂血症大鼠的氧化应激。过氧化氢酶和超氧化物歧化酶(SOD)的活性均在氧化应激的HepG2细胞中显着增加辛伐他汀(10μM,24​h).除此之外,辛伐他汀恢复了氧化应激细胞的原始细胞形态,抗氧化酶的增加,过氧化氢酶(0.08U/细胞到0.12U/细胞),在HepG2细胞中也观察到SOD(0.57U/细胞至0.74U/细胞)。此外,抗氧化酶如过氧化氢酶的显著增加,SOD,在HFD模型中,辛伐他汀治疗后发现还原型谷胱甘肽(GSH)。此外,我们还观察到脂质过氧化硫代巴比妥酸反应性物质(TBARs)的副产物降解,一氧化氮(NO),和蛋白质羰基水平。这表明辛伐他汀增强了抗氧化酶的活性,经过广泛的临床试验后,可以重新用于治疗人类肝病中的氧化应激。
    Simvastatin is an established anti-hyperlipidemic drug and few studies have indicated its role in the mitigation of oxidative stress. However, a systematic study considering molecular binding/interaction of simvastatin with anti-oxidant enzymes followed by confirmational in vitro and in vivo studies have never been done. We investigated the molecular binding of simvastatin with multiple anti-oxidant enzymes and assessed their levels after the treatment of simvastatin in vitro and in vivo. This study is the first to show the molecular binding of simvastatin to catalase through molecular docking analysis. Moreover, the anti-oxidative properties of simvastatin have not been studied in Lipopolysaccharide (LPS) induced oxidative stress in HepG2 cells. We found that simvastatin effectively attenuated oxidative stress in LPS induced HepG2 cells and high-fat diet (HFD) fed hyperlipidemic rats by increasing the levels of antioxidant enzymes. The activity of catalase and superoxide dismutase (SOD) both increased significantly in oxidatively stressed HepG2 cells after the treatment with simvastatin (10 ​μM, 24 ​h). In addition to this, he original cell morphology of oxidatively stressed cells was restored by simvastatin, and an increase in antioxidant enzymes, catalase (0.08 U/cells to 0.12 U/cells), and SOD (0.57 U/cells to 0.74 U/cells) was also noted in HepG2 cells. Furthermore, a significant increase in the antioxidant enzymes such as Catalase, SOD, and reduced glutathione (GSH) was noted after simvastatin treatment in the HFD model. Moreover, we also observed degradation of by-products of lipid peroxidation thiobarbituric acid reactive substances (TBARs), nitric oxide (NO), and protein carbonyl levels. This indicates that simvastatin enhances anti-oxidant enzyme activities and can be repurposed for the treatment of oxidative stress in liver diseases in humans after extensive clinical trials.

    小檗碱(BBR)是一种植物来源的季异喹啉生物碱,具有降低胆固醇和抗高脂血症的作用。本研究的目的是设计和产生BBR负载的前体脂质体(PLs)作为高剂量脂质体的固体模板,提高BBR的口服生物利用度和治疗效果。使用空气悬浮涂覆(分层)方法来产生负载BBR的PL。大小,分布大小,形态学,评估最终重构的脂质体的包封率(EE)。在大鼠和小鼠体内研究了脂质体中BBR的口服生物利用度和内源性胆固醇降低作用。分别。负载BBR的PL在微米级载体颗粒(甘露醇)周围显示出平滑的BBR嵌入膜。重构的BBR负载脂质体具有纳米级平均尺寸(116.6±5.8nm),窄尺寸分布(多分散指数,PDI0.269±0.038),和高EE(87.8±1.0%)。与用纯BBR获得的生物利用度相比,以100mg/kg的剂量在大鼠中重构的装载BBR的脂质体的口服生物利用度甚至增加了628%(根据90%置信区间)。在每日口服剂量100mg/kg的P-407中负载BBR的脂质体降低了总胆固醇,甘油三酯和低密度脂蛋白胆固醇(LDL-C)在高脂血症小鼠的15.8%,38.2%,和57.0%,分别。
    Berberine (BBR) is a plant-origin quaternary isoquinoline alkaloid presenting exogenous cholesterol lowering and anti-hyperlipidemia therapeutic effects. The aim of this study was to design and generate BBR-loaded proliposomes (PLs) as solid templates for high-dose liposomes and consequently, to enhance the oral bioavailability and therapeutic effect of BBR. An air-suspension coating (layering) method was used for generating BBR-loaded PLs. The size, distribution size, morphology, and entrapment efficiency (EE) of the final reconstituted liposomes were assessed. The oral bioavailability and endogenous cholesterol lowering effects of BBR loaded in liposomes were investigated in rats and mice, respectively. The BBR-loaded PLs showed a smooth BBR-embedded film around micron-scale carrier particles (mannitol). The reconstituted BBR-loaded liposomes had a nano-scale average size (116.6 ± 5.8 nm), narrow size distribution (polydispersity index, PDI 0.269 ± 0.038), and high EE (87.8 ± 1.0%). The oral bioavailability of reconstituted BBR-loaded liposomes at a dose of 100 mg/kg in rats was increased even 628% compared to that obtained with pure BBR (according to 90% confidence interval). The BBR-loaded liposomes at the daily oral dose 100 mg/kg in P-407- reduced total cholesterol, triglycerides and low-density lipoprotein cholesterol (LDL-C) in hyperlipidemic mice by 15.8%, 38.2%, and 57.0%, respectively.

    SteviarebaudianaBertoni是巴拉圭的本地植物。提取物已被用作著名的甜味剂,来自甜叶菊的生物活性成分对各种疾病具有广泛的治疗潜力。它的药效包括抗高血压,抗肿瘤性,抗糖尿病,和抗高脂血症。他汀类药物(3-氢-3-甲基戊二酰辅酶A还原酶抑制剂)是一类用于治疗动脉粥样硬化的药物。他汀类药物明确靶向HMG-CoA还原酶,胆固醇生物合成限速步骤中的一种酶。尽管广泛用于调节血浆胆固醇水平,该药物的不良反应是临床医生和患者关注的重点.因此,来自甜叶菊的甜菊醇糖苷已被提议作为替代他汀类药物的替代品。来自甜叶菊的二萜苷,例如甜菊苷和莱鲍迪甙A等在减轻胆固醇水平方面的功效已被评估。这些糖苷是治疗和预防动脉内皮下循环脂质滞留引起的动脉粥样硬化的潜在候选者。本综述旨在整合动脉粥样硬化的发病机制。脂滴生物发生及其相关蛋白参与动脉粥样硬化,目前治疗动脉粥样硬化的方法,以及甜叶菊治疗这种疾病的药理潜力。
    Stevia rebaudiana Bertoni is a native plant to Paraguay. The extracts have been used as a famous sweetening agent, and the bioactive components derived from stevia possess a broad spectrum of therapeutical potential for various illnesses. Among its medicinal benefits are anti-hypertensive, anti-tumorigenic, anti-diabetic, and anti-hyperlipidemia. Statins (3-hydro-3-methylglutaryl-coenzyme A reductase inhibitor) are a class of drugs used to treat atherosclerosis. Statins are explicitly targeting the HMG-CoA reductase, an enzyme in the rate-limiting step of cholesterol biosynthesis. Despite being widely used in regulating plasma cholesterol levels, the adverse effects of the drug are a significant concern among clinicians and patients. Hence, steviol glycosides derived from stevia have been proposed as an alternative in replacing statins. Diterpene glycosides from stevia, such as stevioside and rebaudioside A have been evaluated for their efficacy in alleviating cholesterol levels. These glycosides are a potential candidate in treating and preventing atherosclerosis provoked by circulating lipid retention in the sub-endothelial lining of the artery. The present review is an effort to integrate the pathogenesis of atherosclerosis, involvement of lipid droplets biogenesis and its associated proteins in atherogenesis, current approaches to treat atherosclerosis, and pharmacological potential of stevia in treating the disease.

    Allium cepa is used for the prevention and treatment of hyperlipidemia-related diseases such as atherosclerosis in the folk. This study was mainly aimed at investigating the effects of A. cepa extract (ACE) enriched in polyphenols on hyperlipidemia Sprague-Dawley (SD) experiment rat models. The levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), malondialdehyde (MDA), and superoxide dismutase (SOD) activity in serum and liver were measured using ELISA kits. In addition, hematoxylin-eosin (HE) technique was used to observe the liver and the aortic arch pathology. Moreover, western blotting (WB) method was applied to analyze LDL receptor (LDLR) and 3-hydroxy-3-methylglutaryl (HMG)-CoA reductase (HMGCR) in liver. As a result, quercetin (2.42 mg/g DW) and isoquercitrin (4.60 mg/g DW) were the main constituents of ACE using HPLC analysis. Furthermore, ACE reduced the levels of TC, TG, LDL-C, and MDA, and increased HDL levels and elevated SOD activity both in serum and liver in hyperlipidemic SD rats (p < .05). HE results showed that liver fat drops of the rats in ACE group were obviously decreased, and the lipid and foam cells of the aortic arch of the rats in ACE group were markedly ameliorated. WB results showed that ACE promoted the degradation of HMGCR and increased LDLR expression in liver (p < .05). In conclusion, ACE alleviated hyperlipidemia with downregulation of HMGCR and upregulation of LDLR. PRACTICAL APPLICATIONS: Atherosclerosis, a major cardiovascular disease, is the leading cause of mortality and morbidity in the developed countries. Moreover, accumulating data indicate that, during atherosclerosis development, hyperlipidemia is an important risk factor. To date, hyperlipidemia is mainly treated with hyperlipidemic agents including statins, in spite of the side effects and poor tolerance in some patients. In addition, Allium cepa is a medicinal and edible plant. Furthermore, A. cepa is used for the prevention and treatment of hyperlipidemia-related diseases such as atherosclerosis in the folk. But the underlying mechanism is still unclear. In fact, this research showed that A. cepa extract (ACE) alleviated hyperlipidemia with downregulation of HMGCR and upregulation of LDLR, suggesting that ACE might be a potential option for hyperlipidemia as non-statin lipid-lowering agent.

    背景:四妙永安汤(SMYAD)是一种著名的中药配方,在中国古代已经使用了几个世纪,用于治疗血栓闭塞性脉管炎。由于其悠久的使用历史,它在中国已经被用于治疗患者数千年了。近年来,SMYAD已广泛用于治疗心血管和内分泌疾病。显示出显着增加血清中高密度脂蛋白胆固醇水平并降低总胆固醇和低密度脂蛋白胆固醇水平。
    目的:在此,采用基于HPLC-MS/MS方法的血清代谢组学方法评价SMYAD对高脂饮食诱导的高脂血症的治疗效果,探讨高脂血症的治疗机制。
    方法:首先,体重的变化,肝脏组织病理学,和血清生物化学,包括肝毒性相关酶的水平,氧化应激指标,并监测大鼠的炎症因子,评价SMYAD对高脂饮食诱导的高脂血症的治疗作用。然后,应用了血清代谢组学方法,使用主成分分析(PCA)和偏最小二乘判别分析(PLS-DA)对不同的组进行聚类,以及筛选出敏感和可靠的生物标志物。最后,分析了与特定生物标志物相关的代谢途径,了解SMYAD作用的可能机制。
    结果:结果表明SMYAD具有明显的抗高脂血症作用,抗氧化剂,和抗炎作用。根据血清代谢组学分析结果,与对照大鼠相比,高脂血症大鼠显示出完全不同的结果;SMYAD治疗组大鼠的代谢物谱以剂量依赖性方式显示出与正常对照组相当的趋势。此外,与丙酮酸代谢相关的12种生物标志物,牛磺酸和下牛磺酸代谢,TCA循环,胆汁酸代谢,和葡萄糖代谢被识别和确认,阐明SMYAD的作用机制。
    结论:使用代谢组学技术,据预测,SMYAD的治疗作用与其抗氧化、抗炎活性和丙酮酸盐的调节有关,高血脂状态下的牛磺酸和下牛磺酸代谢途径。这项研究为SMYAD的临床应用提供了证据,并彻底探索了该中药的作用机制。
    BACKGROUND: The Si-miao-yong-an decoction (SMYAD) is a famous traditional Chinese medicinal formula that has been used for centuries in ancient China for treating thromboangiitis obliterans. Because of its long history of use, it has been used to treat patients in China for thousands of years. In recent years, SMYAD has been widely used for treating cardiovascular and endocrine diseases. It was shown to significantly increase high-density lipoprotein-cholesterol levels and reduce total cholesterol and low-density lipoprotein-cholesterol levels in the serum.
    OBJECTIVE: Herein, a serum metabonomics approach based on the HPLC-MS/MS method was adopted to evaluate the therapeutic effect of SMYAD on high-fat diet-induced hyperlipidemia, and investigate the mechanisms for treating hyperlipidemia.
    METHODS: Firstly, the change in body weight, liver histopathology, and serum biochemistry, including that in the levels of hepatotoxicity-related enzymes, oxidative stress indexes, and inflammatory factors were monitored in rats, to evaluate the therapeutic effect of SMYAD on high-fat diet-induced hyperlipidemia. Then, a serum metabolomics approach was applied, to cluster different groups using principle component analysis (PCA) and partial least squares discriminant analysis (PLS-DA), as well as to screen out sensitive and reliable biomarkers. Finally, the metabolic pathways associated with specific biomarkers were analyzed, to understand the possible mechanism underlying the action of SMYAD.
    RESULTS: The results indicated that SMYAD had significant anti-hyperlipidemic, anti-oxidant, and anti-inflammatory effects. Based on the results of serum metabolomics analysis, the hyperlipidemic rats showed completely different results compared to the control rats; metabolite profiles of rats from the SMYAD treatment groups showed a trend comparable to those of the normal control group in a dose-dependent manner. Besides, twelve biomarkers associated with pyruvate metabolism, taurine and hypotaurine metabolism, TCA cycle, bile acid metabolism, and glucose metabolism were identified and confirmed, to clarify the mechanism of action of SMYAD.
    CONCLUSIONS: Using metabonomics technology, it was predicted that the therapeutic effects of SMYAD were associated with its anti-oxidation as well as anti-inflammatory activities and the adjustment of the pyruvate, taurine as well as hypotaurine metabolism pathways in the hyperlipidemic state. This study provided evidence regarding the clinical application of SMYAD and thoroughly explored the mechanism underlying the action of this traditional Chinese medicine.

    Background and Objectives: Dyslipidemia is gaining much attention among healthcare professionals because of its high association with the malfunctioning of a number of normal physiological and metabolic processes in the body. Obesity is directly interconnected with dyslipidemia and is said to be a denouement of hyperlipidemia and, if left untreated, may lead to intense damage to organs that are directly involved in fat metabolism. The objective of this study was to investigate the synergistic antiobesity and anti-hyperlipidemic activities along with hepato- and renoprotective potential of nanoemulsomes (NES) of lovastatin (LTN)-loaded ginger (GR) and garlic (GL) oils. Materials and Methods: LTN nanoemulsomes co-encapsulated with GR oil and GL oil were prepared by a thin hydration technique. Eight-week-old male Wistar rats weighing 200-250 g were induced with hyperlipidemia via a high-fat diet (HFD) comprising 40% beef tallow. Body weight, serum biochemical lipid parameters, and those for liver and kidney functions, serum TC, LDL-C, vLDL-C, HDL-C, TG, atherogenic index (AI), ALT, AFT, ALP, γ-GT, total protein (TP), serum albumin and globulin ratio (A/G), serum creatinine, blood urea nitrogen (BUN) and blood urea, and histopathology of hematoxylin and eosin (H&E) stained liver and kidney sections of all aforementioned groups were examined in the treated animals. Results: Nanoemulsomes of LTN-loaded GR and GL oils provided synergistic effects with LTN, exerted better ameliorative actions in reducing serum TC, LDL-C, vLDL-C, triglycerides, and AI, and improved serum HDL-C levels. Serum ALT, AST, ALP, and γ-GT levels were in the normal range for nanoemulsome groups. H&E stained liver and kidney sections of these animals confirmed better hepatoprotective and renoprotective effects than LTN alone. Serum biochemical parameters for renal functions also claimed to be in the moderate range for nanoemulsome-treated groups. Conclusion: This study demonstrated that nanoemulsomes of LTN-loaded GR and GL oils synergistically provided better antihyperlipidemic, hepatoprotective, and renoprotective effects as compared to LTN alone.
