The present work aimed to investigate the effects of rosemary extracts on metabolic diseases and the underlying mechanisms of action. Liver cells stably expressing SREBP reporter were used to evaluate the inhibitory effects of different fractions of rosemary extracts on SREBP activity. The obese mice induced by Western-type diet were orally administered with rosemary extracts or vehicle for 7 weeks, the plasma and tissue lipids were analyzed. SREBPs and their target genes were measured by quantitative RT-PCR. We demonstrated that the petroleum ether sub-fraction of rosemary extracts(PER) exhibited the best activity in regulating lipid metabolism by inhibiting SREBPs, while water and n-Bu OH sub-fraction showed the SREBPs agonist-effect. After PER treatment, there was a significant reduction of total SREBPs in liver cells. PER not only decreased SREBPs nuclear abundance, but also inhibited their activity, resulting in decreased expression of SREBP-1c and SREBP-2 target genes in vitro and in vivo. Inhibiting SREBPs by PER decreased the total triglycerides and cholesterol contents of the liver cells. In the mice fed with Western-type diet, PER treatment decreased TG, TC, ALT, glucose, and insulin in blood, and improved glucose tolerance and insulin sensitivity. Furthermore, PER treatment also decreased lipid contents in liver, brown adipose tissue, and white adipose tissue. Our results from the present study suggested that petroleum ether fraction of rosemary extracts exhibited the best potential of improving lipid metabolism by inhibiting SREBPs activity.展开更多

Methods: Seventy-six patients of hyperlipidemia were randomly divided into two groups, the XZK group (n=38) treated with XZK 600mg, taken two times per day and the Simvastatin (SIM) group (n = 38) treated with SIM 20mg per day, with the treatment lasting 8 weeks for both groups. Levels of fasting serum lipids, including total cholesterol (TC), triglyceride (TG), high and low density lipoprotein cholesterol (HDL-C and LDL-C), plasma GMP-140, fibrinogen (FIB), tissue plasminogen activator (t-PA), plasminogen activator inhibitor type-1 (PAI-) and prothrombin time (PT) were all measured before and 8 weeks after treatment. Data were compared before and after treatment and also compared with those measured in 20 healthy subjects of control. Results: Before treantment the levels of TC, TG and LDL-C were obviously higher and HDL-C level was significantly lower in hyperlipidemia patients than those in healthy subjects (P<0.05 or P<0.01). After 4-8 weeks of XZK treatment, the levels of TC, TG, LDL-C and FIB and activities of GMP-140 and PAI-1 were obviously lowered (P<0. 05 or P<0. 01). But in the SIM group there was no obvious change in FIB (P>0.05), instead it showed obvious increase of HDL-C and decrease of TC and LDL-C after treatment (P<0.05 or P<0.01). Conclusion: XZK could inhibit platelet activity and improve coagulation-fibrinolysis function, besides its lipids lowering effect.展开更多

Methods： Eighty cases of type 2 DM patients with hyperlipidemia were randomized into two groups, 40 in each group. The patients in the treated group took orally TZA capsules at the dose of 0.9 g 3 times a day and Sim 10 mg at bedtime. And the patients in the control group were treated with Sim 20 mg alone at bedtime. Both regimens lasted for 12 weeks. Before and after the study the changes of blood lipid levels and adverse reaction were investigated. Results. The serum levels of total cholesterol （TO）, triglycerides （TG） and low density lipoprotein-cholesterol （LDL-C） were decreased respectively by 28.8%, 18.2% and 26.3% in the treated group; and by 29.4%, 19.4% and 24.6% in the control group. On the contrary, high density lipoprotein-cholesterol （HDL-C） was increased by 23.5% in the treated group and by 29.4% in the control group. All these changes were statistically significant before and after treatment （all P〈0.05）, but they did not differ statistically between the two groups （P〉0.05）. There was no significant changes in hemoglobin A1 c （HbA1c）. Patients in the treated group did not develop any adverse reactions. However, ALT was found to be higher above the normal range in 5% of the patients in the control group. Conclusion： In treating hyperlipidemia in DM patients, combination of TZA with Sim 10 mg taken daily achieved satisfactory efficacy which was similar to Sim 20 mg daily alone. But the combination therapy conducted in the treated group proved to be better in safety, and could overcome adverse reactions resulting from Sim that was seen in the control group.展开更多

METHODS： The plasma metabolite profiles of 31 patients with the syndrome of phlegm and blood stasis in hyperlipidemia and As, 6 patients with syn- dromes without phlegm and blood stasis, and 10 healthy subjects were analyzed by gas chromatog- raphy-mass spectrometry （GC-MS）. Partial least squares-discriminant analyses （PLS-DA） were used to carry out the pattern-recognition analyses of the data. The plasma metabolic biomarkers of patients were obtained by variable importance plot value （VlP value） and Student＇s t-test. The structures ofbiomarkers were defined by the National Institute of Standards and Technology （NIST） database. RESULTS： PLS-DA score plots of plasma metabo- Iomes did not show overlap between the phlegm-blood stasis syndrome group and syn- dromes without phlegm and blood stasis group, whereas significant differences in the concentra- tions in the plasma of 5 metabolites were found （P〈 0.05）. They were identified as urine, isoleucine, gluc- uronic acid, palmitic acid and glycerol by searching in NIST database. The concentrations of four metab- olites in the plasma of patients with syndrome of phlegm and blood stasis were higher than those with syndromes without phlegm and blood stasis, whereas the glycerol concentration was lower. CONCLUSION： Compared with patients with syn- dromes without phlegm and blood stasis, five me- tabolites showed abnormal levels in patients with the syndrome of phlegm and blood stasis. These metabolites could be diagnostic and prognostic biomarkers.展开更多

The search for a novel effective remedy represents an important task for modern medicine. A total mixture of phospho- and glycolipids from sea macrophytes Sargassum pallidum, Ulva fenestrata, Zostera marina was separated and the fatty acid composition was determined. The biological activity of the mixtures of polar lipids and natural redox-active compounds (echinochrome A from the flat sea urchin Scaphechinus mirabilis and a polyphenolic complex from the sea grass Zostera marina) was studied under conditions of impairments of carbohydrate and lipid metabolism. Doses and compositions of mixtures of pola lipids and redox-active compounds possessing high corrective activity were optimized in mice with the experimental model of hyperlipidemia and diabetes. Based on these results possible mechanisms of the effects of polar lipids containing various polyunsaturated fatty acids and the investigated redox-active compounds (echinochrome A, rosmarinic acid, luteolin and its sulphate conjugates) have been proposed. The developed compositions may be used for creation of new biologically active additives and remedies.展开更多

文摘Fucoxanthin,a kind of exclusively algae-derived carotenoids,could reduce lipid content and regulate gut microbiota composition in obese mice,showing potential in preventing hyperlipidemia.This study aimed to illustrate fucoxanthin efficacy in modulating lipid metabolism in serum and liver of high-fat-induced hyperlipidemia mice,as well as investigate the underlying association with gut microbiota changes.Results showed that fucoxanthin significantly reduced body weight gain and body white fat of the mice.In the serum,total triglycerides(TG),total cholesterol(TC)contents were significantly decreased and high-densitylipoprotein cholesterol levels was significantly upregulated.Moreover,fucoxanthin remarkedly prevented lipid accumulation in the liver.Especially,metabolomics results showed that lipids and lipid-like molecules were significantly downregulated compared with the control,indicating the advance of hepatic lipid metabolism.Bile acids profile in the liver was also greatly changed by fucoxanthin.Meanwhile,fucoxanthin remodeled gut microbiota composition and promoted the relative abundance of Desulfovibrio,Blautia and Clostridia genera.Finally,correlation analysis revealed that these gut microbiota changes were closely related with hepatic metabolites/metabolism and serum lipids.Altogether,this study showed great potential of fucoxanthin in improving serum lipids profile,hepatic lipids and bile acids metabolism of hyperlipidemia mice,which was associated with gut microbiota alteration.

文摘The aim of this study was to explore the mechanism of action of sea buckthorn polyphenols in the treatment of hyperlipidemia through network pharmacology and molecular docking.The TCMSP pharmacology database was used to screen the polyphenols present in sea buckthorn,and then the SwissTargetPrediction and Uniprot databases were used to obtain the potential targets of sea buckthorn polyphenols,which were supplemented by the literature.In total,7 polyphenols and 154 potential targets were obtained.Through GeneCards,OMIM database,1358 hyperlipidemia-related targets were collected.We found that there were 101 targets at the intersection of components and diseases.Through GO and KEGG enrichment analysis,27 core targets were obtained,which were AKT1,TNF,TP53,IL-6,etc.in order of degree value.174 pathways were obtained from KEGG enrichment analysis,including AGE-RAGE signaling pathway in diabetic complications,fl uid shear stress and atherosclerosis,lipid and atherosclerosis,etc.The molecular docking of the main components to the targets was performed using OpenBabelGUI,AutoDockTools-1.5.6 software.Finally,the results were visualized using Cytoscape 3.9.1 software.The molecular docking results showed that sea buckthorn polyphenols have good binding ability with the key targets.Among them,such as quercetin and kaempferol,have good binding ability with TNF,TP53 and IL-6.For example,TNF binds to quercetin with a binding energy of-5.34 kcal/mol and to kaempferol with a binding energy of-6.22 kcal/mol;TP53 binds to kaempferol with a binding energy of-5.32 kcal/mol;IL-6 binds to quercetin with a binding energy of-5.62 kcal/mol,etc.Therefore,the network pharmacology study showed that the treatment of hyperlipidemia by sea buckthorn polyphenols can be realized by multi-component-multi-target-multi-pathway together,which provides some reference for the later study of sea buckthorn polyphenols in the treatment of hyperlipidemia.
文摘Background In recent years,the incidence of coronary heart disease(CHD)has continued to rise,and its comorbidity with hyperlipidemia significantly increases the mortality risk in patients.Statin monotherapy faces limitations in efficacy for some patients and raises potential safety concerns.Ezetimibe,as a novel lipid-modulating agent,exhibits potential advantages in the treatment of hyperlipidemia.Based on this,the present study investigated the therapeutic efficacy of ezetimibe in CHD patients with hyperlipidemia,as well as its effects on lipid metabolism and the amelioration of atherosclerosis.Methods In this study,150 clinical cases with CHD and hyperlipidemia admitted in our hospital from July 2022 to July 2024 were collected for retrospective analysis.According to different treatment methods,they were randomly divided into the Atorvastatin group(control group,n=75)and the Atorvastatin+Ezetimibe group(experimental group,n=75).Control group received atorvastatin monotherapy,while experimental group were administered additional ezetimibe as an adjunct to the atorvastatin-based treatment regimen.The clinical efficacy of the two treatment groups was analyzed,including cardiac function-related parameters such as the cardiac index(CI),cardiac output(CO),left ventricular ejection fraction(LVEF)and left ventricular end-diastolic diameter(LVEDD)before and after treatment.The observed indicators encompassed coronary angiography findings,the Gensini score for assessing coronary stenosis severity,the inflammatory marker high-sensitivity C-reactive protein(hs-CRP),and lipid profile parameters including total cholesterol(TC),triglycerides(TG),high-density lipoprotein cholesterol(HDL-C),and low-density lipoprotein cholesterol(LDL-C).Additionally,the occurrence of adverse reactions during treatment was monitored.Results After treatment,the total effective rate in experimental group was significantly higher than that in control group,with a statistically significant difference(P<0.05).In the comparison of the baseline data,both groups showed marked improvements in CI,CO,LVEF,and HDL-C.However,at the same time points,the experimental group demonstrated significantly better results in these parameters than control group(P<0.05).Additionally,LVEDD,LDL-C,hs-CRP and Gensini scores were significantly reduced after treatment in both groups compared to pretreatment levels.Moreover,at identical time points,the aforementioned parameters in the experimental group demonstrated significantly greater reductions compared to control group(P<0.05).Regarding safety assessment,comparative analysis of adverse drug reaction(ADR)incidence rates between the two treatment groups revealed no statistically significant difference(P>0.05).Conclusions In patients with CHD complicated by hyperlipidemia,ezetimibe demonstrates significant therapeutic advantages.It effectively enhances treatment efficacy,regulates lipid profiles,improves cardiac function,and mitigates the progression of atherosclerosis.This regimen exhibits a favorable safety profile and holds substantial clinical value for both therapeutic processes and rehabilitation outcomes in this patient population.

文摘Background:Aberrant expression of transcription factors(TFs)is a key mechanism mediating tumor immune escape and therapeutic resistance.The involvement of E26 transformation-specific(ETS)family of TFs in immune regulation is not fully understood.The study aimed to elucidate the function of E-twenty-six variant 4(ETV4)in tumor immune evasion and its potential as a predictive biomarker for immunotherapy in melanoma.Methods:The expression patterns of ETS family TFs were analyzed in melanoma and hepatocellular carcinoma(HCC).Single-cell RNA sequencing(scRNA-seq)was used to dissect the cellular expression and function of ETV4 in the tumor microenvironment.Functional studies and murine models were employed to investigate the role of ETV4 in T cell-mediated tumor killing and tumor growth.The correlation between ETV4 expression level and patient responsiveness to programmed cell death protein 1(PD-1)blockade therapy was evaluated.Results:TFs in the ETS family were found to effectively stratify melanoma and HCC patients into prognostic subgroups.In melanoma,the polyoma enhancer activator 3(PEA3)subfamily,particularly ETV4 and ETV5,showed a negative correlation with immune infiltration.scRNA-seq analysis showed that ETV4 is preferentially expressed in melanoma cells and involves in mediating tumor-immunocyte interactions.Functional studies demonstrated that ETV4 impairs T cell-mediated tumor killing by transcriptionally upregulating programmed death-ligand 1(PD-L1).In immunocompetent murine models,ETV4 downregulation significantly suppressed tumor growth.Furthermore,high ETV4 expression correlated with poor responses to anti-PD-1 therapy.Conclusion:Our findings identify ETV4 as a key transcriptional regulator of immune evasion in melanoma by controlling PD-L1 expression.ETV4 may act as a predictive biomarker for immunotherapy outcomes.

文摘As a culinary and medicinal herb, rosemary is widely used. The present work aimed to investigate the effects of rosemary extracts on metabolic diseases and the underlying mechanisms of action. Liver cells stably expressing SREBP reporter were used to evaluate the inhibitory effects of different fractions of rosemary extracts on SREBP activity. The obese mice induced by Western-type diet were orally administered with rosemary extracts or vehicle for 7 weeks, the plasma and tissue lipids were analyzed. SREBPs and their target genes were measured by quantitative RT-PCR. We demonstrated that the petroleum ether sub-fraction of rosemary extracts(PER) exhibited the best activity in regulating lipid metabolism by inhibiting SREBPs, while water and n-Bu OH sub-fraction showed the SREBPs agonist-effect. After PER treatment, there was a significant reduction of total SREBPs in liver cells. PER not only decreased SREBPs nuclear abundance, but also inhibited their activity, resulting in decreased expression of SREBP-1c and SREBP-2 target genes in vitro and in vivo. Inhibiting SREBPs by PER decreased the total triglycerides and cholesterol contents of the liver cells. In the mice fed with Western-type diet, PER treatment decreased TG, TC, ALT, glucose, and insulin in blood, and improved glucose tolerance and insulin sensitivity. Furthermore, PER treatment also decreased lipid contents in liver, brown adipose tissue, and white adipose tissue. Our results from the present study suggested that petroleum ether fraction of rosemary extracts exhibited the best potential of improving lipid metabolism by inhibiting SREBPs activity.
文摘Objective: To investigate the effects of Xuezhikang capsule (XZK,血脂康胶囊) on blood lipids level, platelet activation and coagulation-fibrinolysis activity in patients with hyerlipidemia. Methods: Seventy-six patients of hyperlipidemia were randomly divided into two groups, the XZK group (n=38) treated with XZK 600mg, taken two times per day and the Simvastatin (SIM) group (n = 38) treated with SIM 20mg per day, with the treatment lasting 8 weeks for both groups. Levels of fasting serum lipids, including total cholesterol (TC), triglyceride (TG), high and low density lipoprotein cholesterol (HDL-C and LDL-C), plasma GMP-140, fibrinogen (FIB), tissue plasminogen activator (t-PA), plasminogen activator inhibitor type-1 (PAI-) and prothrombin time (PT) were all measured before and 8 weeks after treatment. Data were compared before and after treatment and also compared with those measured in 20 healthy subjects of control. Results: Before treantment the levels of TC, TG and LDL-C were obviously higher and HDL-C level was significantly lower in hyperlipidemia patients than those in healthy subjects (P<0.05 or P<0.01). After 4-8 weeks of XZK treatment, the levels of TC, TG, LDL-C and FIB and activities of GMP-140 and PAI-1 were obviously lowered (P<0. 05 or P<0. 01). But in the SIM group there was no obvious change in FIB (P>0.05), instead it showed obvious increase of HDL-C and decrease of TC and LDL-C after treatment (P<0.05 or P<0.01). Conclusion: XZK could inhibit platelet activity and improve coagulation-fibrinolysis function, besides its lipids lowering effect.
文摘To evaluate the effectiveness and safety of Taizhi＇an （泰脂安, TZA） capsule combined with Simvastatin （Sim） in treating hyperlipidemia in diabetes mellitus （DM） patients. Methods： Eighty cases of type 2 DM patients with hyperlipidemia were randomized into two groups, 40 in each group. The patients in the treated group took orally TZA capsules at the dose of 0.9 g 3 times a day and Sim 10 mg at bedtime. And the patients in the control group were treated with Sim 20 mg alone at bedtime. Both regimens lasted for 12 weeks. Before and after the study the changes of blood lipid levels and adverse reaction were investigated. Results. The serum levels of total cholesterol （TO）, triglycerides （TG） and low density lipoprotein-cholesterol （LDL-C） were decreased respectively by 28.8%, 18.2% and 26.3% in the treated group; and by 29.4%, 19.4% and 24.6% in the control group. On the contrary, high density lipoprotein-cholesterol （HDL-C） was increased by 23.5% in the treated group and by 29.4% in the control group. All these changes were statistically significant before and after treatment （all P〈0.05）, but they did not differ statistically between the two groups （P〉0.05）. There was no significant changes in hemoglobin A1 c （HbA1c）. Patients in the treated group did not develop any adverse reactions. However, ALT was found to be higher above the normal range in 5% of the patients in the control group. Conclusion： In treating hyperlipidemia in DM patients, combination of TZA with Sim 10 mg taken daily achieved satisfactory efficacy which was similar to Sim 20 mg daily alone. But the combination therapy conducted in the treated group proved to be better in safety, and could overcome adverse reactions resulting from Sim that was seen in the control group.

文摘OBJECTIVE： To explore the plasma metabolite pro- files in patients with the syndrome of phlegm and blood stasis in hyperlipidemia and atherosclerosis （As）, and to search for the metabolic biomarkers of the syndrome. METHODS： The plasma metabolite profiles of 31 patients with the syndrome of phlegm and blood stasis in hyperlipidemia and As, 6 patients with syn- dromes without phlegm and blood stasis, and 10 healthy subjects were analyzed by gas chromatog- raphy-mass spectrometry （GC-MS）. Partial least squares-discriminant analyses （PLS-DA） were used to carry out the pattern-recognition analyses of the data. The plasma metabolic biomarkers of patients were obtained by variable importance plot value （VlP value） and Student＇s t-test. The structures ofbiomarkers were defined by the National Institute of Standards and Technology （NIST） database. RESULTS： PLS-DA score plots of plasma metabo- Iomes did not show overlap between the phlegm-blood stasis syndrome group and syn- dromes without phlegm and blood stasis group, whereas significant differences in the concentra- tions in the plasma of 5 metabolites were found （P〈 0.05）. They were identified as urine, isoleucine, gluc- uronic acid, palmitic acid and glycerol by searching in NIST database. The concentrations of four metab- olites in the plasma of patients with syndrome of phlegm and blood stasis were higher than those with syndromes without phlegm and blood stasis, whereas the glycerol concentration was lower. CONCLUSION： Compared with patients with syn- dromes without phlegm and blood stasis, five me- tabolites showed abnormal levels in patients with the syndrome of phlegm and blood stasis. These metabolites could be diagnostic and prognostic biomarkers.

文摘Cardiovascular diseases and diabetes mellitus are leading causes of mortality in modern society. The search for a novel effective remedy represents an important task for modern medicine. A total mixture of phospho- and glycolipids from sea macrophytes Sargassum pallidum, Ulva fenestrata, Zostera marina was separated and the fatty acid composition was determined. The biological activity of the mixtures of polar lipids and natural redox-active compounds (echinochrome A from the flat sea urchin Scaphechinus mirabilis and a polyphenolic complex from the sea grass Zostera marina) was studied under conditions of impairments of carbohydrate and lipid metabolism. Doses and compositions of mixtures of pola lipids and redox-active compounds possessing high corrective activity were optimized in mice with the experimental model of hyperlipidemia and diabetes. Based on these results possible mechanisms of the effects of polar lipids containing various polyunsaturated fatty acids and the investigated redox-active compounds (echinochrome A, rosmarinic acid, luteolin and its sulphate conjugates) have been proposed. The developed compositions may be used for creation of new biologically active additives and remedies.

文摘Huatan Jiangzhuo decoction(HJD)is a combination of six traditional Chinese medicines that were used for lipid metabolism-related disorders,but its efficacy and underlying mechanisms have not been explored by modern research strategies.This study aimed to investigate the therapeutic role of HJD in determining the transcriptome level.Hyperlipidemia model was established by feeding Sprague–Dawley rats with high-fat diet.Differentially expressed genes(DEGs)were detected by high-through transcriptome sequencing,followed by gene ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analysis.The total cholesterol(TC)and triglyceride(TG)levels in hyperlipidemia model rats were significantly increased,whereas high-density lipoprotein(HDL)concentration decreased when compared to normal rats,and HJD significantly downregulated TC concentrations and liver coefficient in the hyperlipidemia rats.Histology staining showed that HDJ greatly recovered the lipid accumulation in rat hepatic stellate cells and aortic arch vascular wall thickness of hyperlipidemia rats.One thousand nine hundred and thirty-six DEGs were identified in the HJD-treated hyperlipidemia rats,which were associated with various biological processes and signaling pathways such as peroxisome proliferator-activated receptors,AMP-activated Protein Kinase,and insulin signaling pathways.Quantitative reverse transcription–polymerase chain reaction further confirmed the downregulated expression of cholesterol 7-α-hydroxylase(CYP7A1),liver orphan receptor(LXRα),peroxisome proliferator-activated receptor gamma(PPARγ),and Sterol Response Element-Binding Protein 1c(SREBP1c)genes in hyperlipidemia rats treated with HJD.Our data first elucidated the gene expression profile of high-fat diet-induced hyperlipidemia in rats after HJD treatment,and lipid metabolism-related genes(CYP7A1,LXRα,PPARγ,and SREBP1c)may be potentially biomarkers for HJD-alleviated hyperlipidemia.
