Jin Z, Wang X. Traditional Chinese medicine and plant-derived natural products in regulating triglyceride metabolism: Mechanisms and therapeutic potential. Pharmacol Res 2024; 208:107387. [PMID: 39216839 DOI: 10.1016/j.phrs.2024.107387] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/08/2024] [Revised: 08/27/2024] [Accepted: 08/28/2024] [Indexed: 09/04/2024]
Abstract
The incidence of cardiometabolic disease is increasing globally, with a trend toward younger age of onset. Among these, atherosclerotic cardiovascular disease is a leading cause of mortality worldwide. Despite the efficacy of traditional lipid-lowering drugs, such as statins, in reducing low-density lipoprotein cholesterol levels, a significant residual risk of cardiovascular events remains, which is closely related to unmet triglyceride (TG) targets. The clinical application of current TG-lowering Western medicines has certain limitations, necessitating alternative or complementary therapeutic strategies. Traditional Chinese medicine (TCM) and plant-derived natural products, known for their safety owing to their natural origins and diverse biological activities, offer promising avenues for TG regulation with potentially fewer side effects. This review systematically summarises the mechanisms of TG metabolism and subsequently reviews the regulatory effects of TCM and plant-derived natural products on TG metabolism, including the inhibition of TG synthesis (via endogenous and exogenous pathways), promotion of TG catabolism, regulation of fatty acid absorption and transport, enhancement of lipophagy, modulation of the gut microbiota, and other mechanisms. In conclusion, through a comprehensive analysis of recent studies, this review consolidates the multifaceted regulatory roles of TCM and plant-derived natural products in TG metabolism and elucidates their potential as safer, multi-target therapeutic agents in managing hypertriglyceridemia and mitigating cardiovascular risk, thereby providing a basis for new drug development.

Comparative Analysis of Metabolite Profiling of Momordica charantia Leaf and the Anti-Obesity Effect through Regulating Lipid Metabolism. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18115584. [PMID: 34073706 PMCID: PMC8197276 DOI: 10.3390/ijerph18115584] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/26/2021] [Revised: 05/14/2021] [Accepted: 05/18/2021] [Indexed: 12/14/2022]
Abstract
This study investigated the effects of Momordica charantia (M. charantia) extract in obesity and abnormal lipid metabolism in mice fed high fat diet (HFD). Fruit, root, stem, and leaf extracts of M. charantia were obtained using distilled water, 70% ethanol and 95% hexane. M. charantia leaf distilled water extract (MCLW) showed the highest antioxidant activity in both 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity tests and reducing power. Metabolite profiles of M. charantia leaf extracts were analyzed for identification of bioactive compounds. HFD-fed mice were treated with MCLW (oral dose of 200 mg/kg/d) for 4 weeks. MCLW reduced lipid accumulation, body weight, organ weight, and adipose tissue volume and significantly improved glucose tolerance and insulin resistance in HFD mice. Furthermore, MCLW administration reduced serum total cholesterol and low-density lipoprotein cholesterol, and increased serum high-density lipoprotein cholesterol compared with HFD mice. Moreover, MCLW significantly reduced the levels of serum urea nitrogen, alanine aminotransferase, alkaline phosphatase, and aspartate aminotransferase; alleviated liver and kidney injury. MCLW decreases expression of genes that fatty acid synthesis; increase the expression of catabolic-related genes. These results indicate that MCLW has an inhibitory effect on obese induced by high fat diet intake, and the mechanism may be related to the regulation of abnormal lipid metabolism in liver and adipose tissue, suggesting that MCLW may be a suitable candidate for the treatment of obesity.

Abstract
Pulmonary arterial hypertension (PAH) is a devastating pulmonary circulation disease lacking high-efficiency therapeutics. The present study aims to decipher the therapeutic mechanism of Rhodiola crenulata, a well-known traditional chinese medicine with cardiopulmonary protection capacity, on PAH by exploiting functional lipidomics. The rat model with PAH was successfully established for first, following Rhodiola crenulata water extract (RCE) treatment, then analysis of chemical constituents of RCE was performed, additional morphologic, hemodynamic, echocardiographic measurements were examined, further targeted lipidomics assay was performed to identify differential lipidomes, at last accordingly mechanism assay was done by combining qRT-PCR, Western blot and ELISA. Differential lipidomes were identified and characterized to differentiate the rats with PAH from healthy controls, mostly assigned to acylcarnitines, phosphatidylcholines, sphingomyelin associated with the PAH development. Excitingly, RCE administration reversed high level of decadienyl-L-carnitine by the modulation of metabolic enzyme CPT1A in mRNA and protein level in serum and lung in the rats with PAH. Furthermore, RCE was observed to reduce autophagy, confirmed by significantly inhibited PPARγ, LC3B, ATG7 and upregulated p62, and inactivated LKB1-AMPK signal pathway. Notably, we accurately identified the constituents in RCE, and delineated the therapeutic mechansim that RCE ameliorated PAH through inhibition of fatty acid oxidation and autophagy. Altogether, RCE might be a potential therapeutic medicine with multi-targets characteristics to prevent the progression of PAH. This novel findings pave a critical foundation for the use of RCE in the treatment of PAH.

Rhodiola Crenulata ameliorates exhaustive exercise-induced fatigue in mice by suppressing mitophagy in skeletal muscle. Exp Ther Med 2020; 20:3161-3173. [PMID: 32855685 PMCID: PMC7444336 DOI: 10.3892/etm.2020.9072] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2019] [Accepted: 05/20/2020] [Indexed: 12/18/2022] Open
Abstract
The aim of present study was to evaluate the potential effects of Rhodiola crenulata oral liquid (RCOL) on exhaustive exercise (EE)-induced fatigue in mice. Male Institute of Cancer Research mice from five treatment groups (n=10 per group) were orally administered with sterilized water for the Control and EE groups and/or RCOL at doses of 1.02, 3.03 and 6.06 ml/kg/day, once daily for 2 weeks. Anti-fatigue activity was subsequently evaluated by measuring the levels of creatine kinase (CK), lactic acid (LA), lactate dehydrogenase (LDH), malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT) and total anti-oxidative capability (T-AOC). Histopathology was assessed using hematoxylin and eosin staining. Ultrastructures of mitochondria were observed by transmission electron microscopy. Energy supply capacity was assessed using citrate synthase (CS), succinate dehydrogenase (SDH), Na+-K+-ATPase, and liver and quadriceps glycogen content assays. Expression levels of mRNA and protein associated with mitophagy in the skeletal muscle were measured by reverse transcription-quantitative PCR and western blotting, respectively. RCOL was observed to markedly inhibit fatigue-induced oxidative stress by increasing the activities of SOD, CAT and T-AOC, whilst reducing the accumulation of LA, CK, LDH and MDA. Histological analysis of the quadriceps femoris tissue suggested increased numbers of muscle fibers in the RCOL groups compared with those in the EE group. RCOL administration was found to reverse EE-induced mitochondrial structural damage and alleviated defects inflicted onto the energy supply mechanism by increasing CS, SDH, Na+-K+-ATPase and glycogen levels. Additionally, RCOL reduced the protein expression of PTEN-induced kinase 1 (PINK1), Parkin, microtubule-associated proteins 1A/1B light chain 3, sequestosome 1 and ubiquitin, whilst lowering the gene expression of PINK1 and Parkin. Taken together, results from the present study clarified the anti-fatigue effect of RCOL, where the underlying mechanism may be associated with increased antioxidant activity, enhanced energy production and the inhibition of mitophagy by suppressing the PINK1/Parkin signaling pathway.

Abstract
Adenosine monophosphate-activated protein kinase (AMPK) is the main energy sensor in mammals, but limited information is available regarding its role as an energy sensor in nutrient-restricted fish particularly in period of overwinter starvation. The present study aimed to investigate the role of AMPK in the grass carp Ctenopharyngodon idellus through characterization of AMPK full-length cDNAs and the measurement of transcriptional activity in response to overwinter starvation. AMPK is a heterotrimeric serine/threonine kinase that consists of a catalytic alpha (α) subunit complexed with two regulatory subunits, beta (β) and gamma (γ). In our study, we identified nine isoforms of the AMPK family in grass carp and obtained their complete coding sequences (CDS). In the grass carp, the α subunit is encoded by two isoforms (α1 and α2). The β and γ subunits are encoded by three (β1a, β1b, β2) and four isoforms (γ1, γ2a, γ2b, γ3), respectively. AMPK isoforms in grass carp possess structural features similar to mammalian AMPK and exhibit a high degree of homology with other fish and vertebrate AMPK sequences. The mRNA of nine grass carp AMPK isoforms were found to be expressed in a wide range of tissues in vivo, but the abundance of each AMPK mRNA demonstrated a tissue-dependent expression pattern, indicating that they might be key complexes playing the role of energy metabolism sensors during overwinter starvation conditions. Compared to expression levels in control fish (week 0), the expression of various AMPK isoforms significantly increased in the hepatopancreas of fish exposed to 1 week or more of overwinter starvation conditions as follows: week 1 (AMPK α1 and AMPK α2), week8 (AMPK β1b and AMPK γ2b), week 12 (AMPK β2 and AMPK γ1), and week 16 (AMPK β1a, AMPK γ2a, and AMPK γ3). Additionally, compared to expression levels in control fish (week 0), the expression of various AMPK isoforms significantly increased in the adipose tissue of fish exposed to 1 week or more of overwinter starvation conditions as follows: week 1(AMPK β1a and AMPK β1b), week 4 (AMPK α1, AMPK α2, AMPK γ1, AMPK γ2b and AMPK γ3), and week 8 (AMPK β2 and AMPK γ2a). Further in vitro analysis revealed that the mRNA levels of AMPK isoforms in hepatocytes (AMPK α1, AMPK α2, AMPK β1a, AMPK β1b, AMPK β2, AMPK γ2b and AMPK γ3) and adipocytes (AMPK γ2a, AMPK γ2b and AMPK γ3) changed significantly with in the first 24 h of exposure to the overwinter starvation conditions. These findings confirm that nine AMPK subunits are present in grass carp and that all encode proteins with conserved functional domains. The nine AMPK subunits are all regulated at the transcriptional levels to manage excess energy expenditure during overwinter starvation stress.

Abstract
Over the past three decades, the knowledge gained about the mechanisms that underpin the potential use of Rhodiola in stress- and ageing-associated disorders has increased, and provided a universal framework for studies that focused on the use of Rhodiola in preventing or curing metabolic diseases. Of particular interest is the emerging role of Rhodiola in the maintenance of energy homeostasis. Moreover, over the last two decades, great efforts have been undertaken to unravel the underlying mechanisms of action of Rhodiola in the treatment of metabolic disorders. Extracts of Rhodiola and salidroside, the most abundant active compound in Rhodiola, are suggested to provide a beneficial effect in mental, behavioral, and metabolic disorders. Both in vivo and ex vivo studies, Rhodiola extracts and salidroside ameliorate metabolic disorders when administered acutely or prior to experimental injury. The mechanism involved includes multi-target effects by modulating various synergistic pathways that control oxidative stress, inflammation, mitochondria, autophagy, and cell death, as well as AMPK signaling that is associated with possible beneficial effects on metabolic disorders. However, evidence-based data supporting the effectiveness of Rhodiola or salidroside in treating metabolic disorders is limited. Therefore, a comprehensive review of available trials showing putative treatment strategies of metabolic disorders that include both clinical effective perspectives and fundamental molecular mechanisms is warranted. This review highlights studies that focus on the potential role of Rhodiola extracts and salidroside in type 2 diabetes and atherosclerosis, the two most common metabolic diseases.

Rhodiola/Cordyceps-Based Herbal Supplement Promotes Endurance Training-Improved Body Composition But Not Oxidative Stress and Metabolic Biomarkers: A Preliminary Randomized Controlled Study. Nutrients 2019; 11:nu11102357. [PMID: 31623349 PMCID: PMC6835767 DOI: 10.3390/nu11102357] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2019] [Revised: 09/30/2019] [Accepted: 09/30/2019] [Indexed: 12/23/2022] Open
Abstract
Rhodiola crenulata (R) and Cordyceps sinensis (C) are commonly used herbs that promote health in traditional Chinese medicine. These two herbs have also been shown to exhibit anti-inflammation and antioxidant functions. Regular endurance training reveals potent endurance capacity, body composition improvement, and metabolic-related biomarker benefits. However, it is not known whether the combination of Rhodiola crenulata and Cordyceps sinensis (RC) supplementation during endurance training provides additive health benefits. The purpose of this study was to investigate the effects of 8-week endurance training plus RC supplementation on body composition, oxidative stress, and metabolic biomarkers in young sedentary adults. Methods: Fourteen young sedentary adults (8M/6F) participated in this double-blind randomized controlled study. Participants were assigned to exercise training with placebo groups (PLA, n = 7, 4M/3F; age: 21.4 ± 0.4 years) and exercise training with the RC group (RC, 20 mg/kg/day; n = 7, 4M/3F; age: 21.7 ± 0.4 years). Both groups received identical exercise training for eight weeks. The body composition, circulating oxidative stress, and blood metabolic biomarkers were measured before and after the 8-week intervention. Results: Improvement in body composition profiles were significantly greater in the RC group (body weight: p = 0.044, BMI: p = 0.003, upper extremity fat mass: p = 0.032, lower extremity muscle mass: p = 0.029, trunk fat mass: p = 0.011) compared to the PLA group after training. The blood lipid profile and systemic oxidative stress makers (thiobarbituric reactive substanceand total antioxidant capacity) did not differ between groups. Although endurance training markedly improved endurance capacity and glycemic control ability (i.e., fast blood glucose, insulin, and HOMA index), there were no differences in these variables between treatments. Conclusions: In this preliminary investigation, we demonstrated that an 8-week RC supplementation (20 mg/kg/day) faintly enhanced endurance training-induced positive adaptations in body composition in young sedentary individuals, whereas the blood lipid profile and systemic oxidative stress states were not altered after such intervention.

Lycopene attenuates western-diet-induced cognitive deficits via improving glycolipid metabolism dysfunction and inflammatory responses in gut-liver-brain axis. Int J Obes (Lond) 2018; 43:1735-1746. [PMID: 30538283 DOI: 10.1038/s41366-018-0277-9] [Citation(s) in RCA: 43] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2018] [Revised: 09/26/2018] [Accepted: 11/05/2018] [Indexed: 01/07/2023]
Abstract
BACKGROUND/OBJECTIVES The aim of the current study was to investigate the inhibitory effect of lycopene (LYC), a major carotenoid present in tomato, on high-fat and high-fructose western diet (HFFD)-induced cognitive impairments and the protective effects on HFFD-elicited insulin resistance, lipid metabolism dysfunction and inflammatory responses in the gut-liver-brain axis. SUBJECTS/METHODS We randomly assigned 3-month-old C57BL/6 J mice to three groups with different diets: the control group, HFFD group and HFFD + LYC group (LYC, 0.03% w/w, mixed into high-fat diet) for 10 weeks. RESULTS The results of the Y-maze task and Morris water maze tests demonstrated that LYC attenuated HFFD-induced memory loss. Moreover, LYC suppressed HFFD-elicited synaptic dysfunction and increased the expressions of SNAP-25 and PSD-95. Furthermore, LYC ameliorated insulin resistance, lipid metabolism dysfunction and inflammatory responses in the mouse brain and liver. LYC also prevente.d intestinal barrier integrity damages and decreased the level of circulating LPS. CONCLUSIONS These results demonstrated that LYC ameliorated HFFD-induced cognitive impairments in a mouse model by improving insulin resistance, lipid metabolism dysfunction and inflammatory responses in the gut-liver-brain axis. These findings indicate that LYC might be a nutritional strategy for western diet-induced dysfunction of the central nervous system.

Abstract
Background and purpose The traditional Chinese medicine – the flower of Edgeworthia gardneri – is reported as an effective therapeutic for type 2 diabetes mellitus (T2DM). Nevertheless, most constituents of the flowers of E. gardneri have not yet been studied. This study was conducted to investigate the effect of quercetin extracted from the flowers of E. gardneri on islet protection and amelioration in T2DM and explore its mechanism. Method Quercetin was extracted from the flowers of E. gardneri and verified by high-performance liquid chromatography. Quercetin or crude extract’s effect on insulin secretion was investigated. ERK1/2 and phospho-ERK1/2 were detected by Western blot analysis, and fluo-3 AM was used to detect intracellular Ca2+. The anti-apoptosis effect of quercetin or crude extract on MIN-6 cells was investigated by thiazolyl blue tetrazolium bromide (MTT) assay and flow cytometry analysis. Activation of caspases and expression of Bcl-2 and BAX were tested by Western blot analysis. In addition, the mitochondrial membrane potential was determined by JC-1 probe. Moreover, in vivo activity was also tested in db/db mice. Results A quercetin level of >10 μmol/L could induce insulin secretion. Intracellular Ca2+ and ERK1/2 were involved in the signaling pathway of quercetin-induced insulin secretion. We also observed that quercetin could inhibit palmitic acid-induced cell apoptosis via suppressing the activation of caspase-3, -9, -12; increasing the ratio of Bcl-2/BAX and reversing the impaired mitochondrial membrane potential. Crude extract’s effect on insulin secretion was similar to that of pure extracted quercetin, while it possessed higher anti-apoptosis activity. Additionally, intraperitoneal glucose tolerance, plasma insulin level, hepatic triglyceride, hepatic glycogen and the pathological histology of both pancreatic islet and liver in db/db mice were significantly improved by the administration of the extracted quercetin. Conclusion Our study indicated that quercetin extracted from the flowers of E. gardneri exerted excellent properties in islet protection and amelioration.

Abstract
Genstein is the most abundant phytoestrogen in soybean that was reported to play positive roles in menopausal syndrome and metabolic syndrome. In the present study, we investigated the effects and potential mechanisms of genistein against progression of nonalcoholic fatty liver disease (NAFLD) in BRL cells treated with fatty acid mixture (oleate/palmitate, 2:1 ratio). Our data demonstrated that genistein remarkably improved fatty acid mixture-induced hepatocelluler fat accumulation, inhibited upregulation of genes expression related to fatty acid synthesis, and derepressed those associated with fatty acid oxidation. In addition, the results displayed that genistein promoted the phosphorylation of adenosine monophosphate-activated protein kinase (AMPK) suppressed by fatty acid, which were significantly weakened by compound C, an AMPK inhibitor. Taken all together, genistein is capable to ameliorate fat accumulation through regulation of fatty acid metabolism mediated by AMPK activation in BRL cells. Further investigations are needed to verify the protective effects of genistein on NAFLD model in in vivo animal study or in vitro human cell lines along with absorption, distribution, metabolism, and excretion studies of genistein. PRACTICAL APPLICATION Genistein is able to ameliorate fat accumulation through regulation of fatty acid metabolism mediated by AMPK activation in vitro.

Abstract
The prevalence of non-alcoholic fatty liver disease (NAFLD), which is developed from hepatic steatosis, is increasing worldwide. However, no specific drugs for NAFLD have been approved yet. To observe the effects of Rho, a fraction from Rhodiola crenulate, on non-alcoholic hepatic steatosis, three mouse models with characteristics of NAFLD were used including high-fat diet (HFD)-induced obesity (DIO) mice, KKAy mice, and HFD combined with tetracycline stimulated Model-T mice. Hepatic lipid accumulation was determined via histopathological analysis and/or hepatic TG determination. The responses to insulin were evaluated by insulin tolerance test (ITT), glucose tolerance test (GTT), and hyperinsulinemic-euglycemic clamp, respectively. The pathways involved in hepatic lipid metabolism were observed via western-blot. Furthermore, the liver microcirculation was observed by inverted microscopy. The HPLC analysis indicated that the main components of Rho were flavan polymers. The results of histopathological analysis showed that Rho could ameliorate hepatic steatosis in DIO, KKAy, and Model-T hepatic steatosis mouse models, respectively. After Rho treatment in DIO mice, insulin resistance was improved with increasing glucose infusion rate (GIR) in hyperinsulinemic-euglycemic clamp, and decreasing areas under the blood glucose-time curve (AUC) in both ITT and GTT; the pathways involved in fatty acid uptake and de novo lipogenesis were both down-regulated, respectively. However, the pathways involved in beta-oxidation and VLDL-export on hepatic steatosis were not changed significantly. The liver microcirculation disturbances were also improved by Rho in DIO mice. These results suggest that Rho is a lead nature product for hepatic steatosis treatment. The mechanism is related to enhancing insulin sensitivity, suppressing fatty acid uptake and inhibiting de novo lipogenesis in liver.

Abstract
Melaleuca alternifolia concentrate (MAC) is the refined essential oil of the Australian native plant Melaleuca alternifolia. MAC has been reported to suppress the production of pro-inflammatory cytokines in both murine RAW264.7 macrophages and human monocytes stimulated with lipopolysaccharide (LPS). However, the mechanisms involved in this effect remain unclear. This study aims to delineate the molecular mechanisms that drive the anti-inflammatory activity of MAC and its active component, terpinen-4-ol, in macrophages. The effects of MAC on RAW264.7 cells were studied using western blotting, real-time PCR, an electrophoretic mobility shift assay (EMSA), and NF-[Formula: see text]B luciferase reporter assays. Our results showed that MAC significantly increased both the mRNA and protein levels of heme oxygenase-1 (HO-1) via p38 and JNK MAPK activation. In addition, we showed that MAC significantly increased the activation and nuclear translocation of NF-E2-related factor 2 (Nrf2), a key transcription factor regulating HO-1 induction. MAC was also associated with significant inhibition of iNOS expression, NO production, and NF-[Formula: see text]B activation. HO-1 was required for these anti-inflammatory effects as tin protoporphyrin IX (SnPPIX), an HO-1 inhibitor, abolished the effects of MAC on LPS-induced iNOS, NO, and NF-[Formula: see text]B activation. Our results indicate that MAC induces HO-1 expression in murine macrophages via the p38 MAPK and JNK pathways and that this induction is required for its anti-inflammatory activity.

Exercise Combined with Rhodiola sacra Supplementation Improves Exercise Capacity and Ameliorates Exhaustive Exercise-Induced Muscle Damage through Enhancement of Mitochondrial Quality Control.

Abstract
Mounting evidence has firmly established that increased exercise capacity (EC) is associated with considerable improvements in the survival of patients with cardiovascular disease (CVD) and that antistress capacity is a prognostic predictor of adverse cardiovascular events in patients with CVD. Previous studies have indicated that aerobic exercise (AE) and supplementation with Rhodiola sacra (RS), a natural plant pharmaceutical, improve EC and enable resistance to stress; however, the underlying mechanism remains unclear. This study explored the ability of AE and RS, alone or combined, to improve EC and ameliorate exhaustive exercise- (EE-) induced stress and elucidate the mechanism involved. We found that AE and RS significantly increased EC in mice and ameliorated EE-induced stress damage in skeletal and cardiac muscles (SCM); furthermore, a synergistic effect was detected for the first time. To our knowledge, the present work is the first to report that AE and RS activate mitophagy, mitochondrial dynamics, and biogenesis in SCM, both in the resting state and after EE. These data indicate that AE and RS synergistically improve EC in mice and protect SCM from EE-induced stress by enhancing mitochondrial quality control, including the activation of mitophagy, mitochondrial dynamics, and biogenesis, both at rest and after EE.

Abstract
Rhodiola crenulata root extract (RCE), a traditional Chinese medicine, has been shown to regulate glucose and lipid metabolism via the AMPK pathway in high glucose (HG) conditions. However, the effect of RCE on HG-induced endothelial dysfunction remains unclear. The present study was designed to examine the effects and mechanisms of RCE against hyperglycemic insult in endothelial cells. Human umbilical vein endothelial cells (HUVECs) were pretreated with or without RCE and then exposed to 33[Formula: see text]mM HG medium. The cell viability, nitrite production, oxidative stress markers, and vasoactive factors, as well as the mechanisms underlying RCE action, were then investigated. We found that RCE significantly improved cell death, nitric oxide (NO) defects, and oxidative stress in HG conditions. In addition, RCE significantly decreased the HG-induced vasoactive markers, including endothelin-1 (ET-1), fibronectin, and vascular endothelial growth factor (VEGF). However, the RCE-restored AMPK-Akt-eNOS-NO axis and cell viability were abolished by the presence of an AMPK inhibitor. These findings suggested that the protective effects of RCE were associated with the AMPK-Akt-eNOS-NO signaling pathway. In conclusion, we showed that RCE protected endothelial cells from hyperglycemic insult and demonstrated its potential for use as a treatment for endothelial dysfunction in diabetes mellitus.

Abstract
OBJECTIVE To investigate the effect of Hugan Qingzhi tablets on lipid metabolism and inflammation in rats fed on high-fat diet and explore the underlying mechanisms. METHODS Sixty male Sprague-Dawley rats were randomly divided into 6 groups, namely HFD group (with high-fat diet and distilled water), control group (with normal diet and distilled water), fenofibrate group (with high-fat diet and treatment with 0.1 g<kg fenofibrate suspension), and low-, moderate- and high-dose Hugan Qingzhi tablet groups (with high-fat diet and treatment with 0.54, 1.08, and 2.16 g<kg Hugan Qingzhi suspension). After daily corresponding treatments for 12 weeks, the histological changes in the liver were observed with HE staining. The serum levels of triglyceride (TG), cholesterol (CHOL), alanine transaminase (ALT), and aspartate aminotransferase (AST), and the levels of TG and CHOL in the hepatic tissue were assayed. The proinflammatory cytokines TNF-α, IL-6 and CRP were detected with enzyme-linked immunoassay, and p-AMPK, SREBP-1c, FASN and NF-αB-p65 expression levels in the liver were determined with qRT-PCR or Western blotting. RESULTS At high and moderate doses, Hugan Qingzhi effectively decreased the levels of ALT, AST, TG and CHOL levels in the serum, lowered the hepatic levels of TNF-α, IL-6 and CRP, enhanced p-AMPK, and reduced the expression of SREBP-1c, FASN and Ac-NF-αB-p65 in the liver of rats fed on high-fat diet. CONCLUSION Hugan Qingzhi tablets alleviates hyperlipidemia and inflammation in rats fed with high-fat diet possibly by activating AMPK pathway and suppress NF-αB activity to arrest the progression of nonalcoholic fatty liver disease.
