Even though the incidence of diabetic retinopathy has declined...Diabetic retinopathy affects a substantial proportion of patients with diabetes mellitus(DM) and is the leading cause of blindness in working-aged adults. Even though the incidence of diabetic retinopathy has declined in the last decades, its prevalence increased and is expected to rise further as a result of the increasing incidence of type 2 DM(T2DM) and the longer life expectancy of patients with DM. The pathogenesis of diabetic retinopathy is multifactorial. Some observational studies suggested an association between dyslipidemia and the development and progression of retinopathy in patients with DM but others did not confirm this association. Regarding lipid-lowering agents, studies that evaluated the role of statins in the management of these patients are mostly small and yielded discrepant results. Large randomized studies with statins in patients with T2DM showed no benefit of these agents on diabetic retinopathy but were not designed to address this effect. In contrast, both preclinical data and two large randomized controlled studies, the FIELD and the ACCORD trial, showed that fenofibrate delays the progression of diabetic retinopathy. Even though the mechanisms underpinning this favorable effect are not entirely clear, these findings suggest that fenofibrate might represent a useful tool for the management of diabetic retinopathy.展开更多

文摘Growing evidence suggests that abnormal lipid metabolism occurs in amyotrophic lateral sclerosis,even in the presymptomatic stage,implying an etiologic link.However,the genetic mechanism underlying altered lipid levels in amyotrophic lateral sclerosis remains elusive.Therefore,in this study,we performed genetic correlation analysis,a cross-trait meta-analysis,tissue-specific enrichment analysis,and bidirectional two-sample Mendelian randomization analysis of European population to explore whether there is a genetic and causal relationship between lipids and amyotrophic lateral sclerosis.The effect of lipid-lowering drugs on amyotrophic lateral sclerosis was also evaluated using a drug target Mendelian randomization approach.The results showed a positive genetic correlation between amyotrophic lateral sclerosis and both high-density lipoprotein cholesterol and apolipoprotein A1 and identified 71 independent shared loci between amyotrophic lateral sclerosis and high-density lipoprotein cholesterol,as well as 55 independent shared loci between amyotrophic lateral sclerosis and apolipoprotein A1.These shared loci were enriched in the lipid metabolic pathway and the alcohol metabolic pathway.Further Mendelian randomization analysis targeting lipid-lowering drugs showed that single nucleotide polymorphisms within the ACLY and PCSK9 genes had a protective effect against amyotrophic lateral sclerosis risk by decreasing low-density lipoprotein cholesterol.The combination of ACLY and PCSK9 inhibitors has a greater protective effect on amyotrophic lateral sclerosis risk than that of PCSK9 inhibitors alone.In summary,there is a common genetic structure between lipids and amyotrophic lateral sclerosis.Mendelian randomization analysis supports an association between elevated blood lipids and the risk of developing amyotrophic lateral sclerosis,and the use of ACLY or PCSK9 inhibitors may improve disease prognosis.

文摘Background:Atherosclerotic cardiovascular disease remains the leading cause of death worldwide.This study aims to explore the impact of national volume-based procurement(NVBP)on Chinese patent medicines and provide evidence for improving policies and promoting rational drug use.Methods:The study was based on data from the China National Health Insurance Agency that spanned January 2019 to December 2020.Descriptive analysis was conducted using volume and expenditure as variables.Interrupted time series analysis was applied to further analyze Chinese patent medicines.Results:The unit prices of atorvastatin and rosuvastatin decreased by 25%-96%,whereas the prices of Zhibitai and Xuezhikang fluctuated slightly.The affordability is measured as the monthly expenditure on treatment divided by the daily wage.After policy implementation,the affordability of atorvastatin and rosuvastatin improved from 0.242 to 0.014 and from 0.247 to 0.019,respectively.The defined daily doses(DDDs)for atorvastatin and rosuvastatin also increased,whereas total expenditures decreased in hospitals of all levels.Both at the national level and at all levels of hospital,the policy had no significant impact on expenditures for Zhibitai and Xuezhikang and their defined daily doses.Conclusions:The NVBP saved costs in the short term by incorporating high-quality,widely used lipid-lowering drugs.Notably,the policy impacted lipid-lowering chemical drugs,whereas Chinese patent medicines remained largely unaffected.Doctors'use of Chinese patent medicines did not decline,highlighting the clinical specificity of these medicines.
文摘Diabetic retinopathy affects a substantial proportion of patients with diabetes mellitus(DM) and is the leading cause of blindness in working-aged adults. Even though the incidence of diabetic retinopathy has declined in the last decades, its prevalence increased and is expected to rise further as a result of the increasing incidence of type 2 DM(T2DM) and the longer life expectancy of patients with DM. The pathogenesis of diabetic retinopathy is multifactorial. Some observational studies suggested an association between dyslipidemia and the development and progression of retinopathy in patients with DM but others did not confirm this association. Regarding lipid-lowering agents, studies that evaluated the role of statins in the management of these patients are mostly small and yielded discrepant results. Large randomized studies with statins in patients with T2DM showed no benefit of these agents on diabetic retinopathy but were not designed to address this effect. In contrast, both preclinical data and two large randomized controlled studies, the FIELD and the ACCORD trial, showed that fenofibrate delays the progression of diabetic retinopathy. Even though the mechanisms underpinning this favorable effect are not entirely clear, these findings suggest that fenofibrate might represent a useful tool for the management of diabetic retinopathy.

文摘Active ingredients from highland barley have received considerable attention as natural products for developing treatments and dietary supplements against obesity.In practical application,the research of food combinations is more significant than a specific food component.This study investigated the lipid-lowering effect of highland barley polyphenols via lipase assay in vitro and HepG2 cells induced by oleic acid(OA).Five indexes,triglyceride(TG),total cholesterol(T-CHO),low density lipoprotein-cholesterol(LDL-C),aspartate aminotransferase(AST),and alanine aminotransferase(ALT),were used to evaluate the lipidlowering effect of highland barley extract.We also preliminary studied the lipid-lowering mechanism by Realtime fluorescent quantitative polymerase chain reaction(q PCR).The results indicated that highland barley extract contains many components with lipid-lowering effects,such as hyperoside and scoparone.In vitro,the lipase assay showed an 18.4%lipase inhibition rate when the additive contents of highland barley extract were 100μg/m L.The intracellular lipid-lowering effect of highland barley extract was examined using 0.25 mmol/L OA-induced HepG2 cells.The results showed that intracellular TG,LDL-C,and T-CHO content decreased by 34.4%,51.2%,and 18.4%,respectively.ALT and AST decreased by 51.6%and 20.7%compared with the untreated hyperlipidemic HepG2 cells.q PCR results showed that highland barley polyphenols could up-regulation the expression of lipid metabolism-related genes such as PPARγand Fabp4.

文摘AIM：To clarify this controversy and to provide evidence for application of lipid lowering agents in treatment of diabetic retinopathy（DR）.METHODS：We searched the databases of Pub Med,Embase and Cochrane Library Central Register of Controlled Trials（CENTRAL）and abstracts from main annual meetings up to January 1,2017.Google scholar and Clinical Trials.gov were also searched for unpublished relevant studies.We included randomized controlled trials（RCTs）that studied lipid-lowering agents in type 1 or type 2 diabetes in this Meta-analysis.The primary endpoint was the progression of DR,and the secondary endpoints included vision loss,development of diabetic macular edema（DME）and aggravation of hard exudates.The pooled odds ratios（OR）with corresponding 95%confidence intervals（95%CIs）were calculated.RESULTS：After systemic and manual literature search by two independent investigators,we included 8 RCTs from 7 published articles with 13 454 participants in this Meta-analysis.The results revealed that lipid-lowering drugs were associated with reduced risk in DR progression[OR=0.77（95%CI：0.62,0.96）,P=0.02].Lipid-lowering agents might have protective effect on DME compared to placebo,although the difference was not statistically significant[OR=0.60（95%CI：0.34,1.08）,P=0.09].However,no significant differences in the worsening of vision acuity[OR=0.96（95%CI：0.81,1.14）,P=0.64]and hard exudates[OR=0.50（95%CI：0.15,1.74）,P=0.28]were found between the lipidlowering drugs and the placebo groups.CONCLUSION：In DR patients,lipid-lowering agents show a protective effect on DR progression and might be associated with reduced risk in the development of DME.However,lipid-lowering agents have no effects on vision loss and hard exudates aggravation.Further clinical trials in larger scale are required to confirm the conclusion of this study and thus justify the use of intensive control lipids with anti-lipid agents at the early stages of DR.
文摘Objective:To investigate the effect of Oroxylum indicum fruit extract on high-fat diet-induced hyperlipidemic mice.Methods:The phytochemical composition of Oroxylum indicum fruit extract was determined by liquid chromatographymass spectrometry/mass spectrometry(LC-MS/MS)and gas chromatography-mass spectrometry.Forty-two male mice were used.The mice were divided into six groups:normal control,high-fat diet control,simvastatin treatment(20 mg/kg BW/day),and Oroxylum indicum fruit extract(100,200,300 mg/kg BW/day)treatment groups.Food intake,body weight,serum parameters,lipid profile,and histopathological lesions of the kidney,liver,and epididymal fat were observed.Results:LC-MS/MS results revealed four major components of Oroxylum indicum fruit extract:luteolin,apigenin,baicalein,and oroxylin A.Twenty-seven volatile oils were identified from Oroxylum indicum fruit extract.Daily oral administration of Oroxylum indicum fruit extract at 100 to 300 mg/kg BW/day significantly reduced the body weight,total cholesterol,triglyceride,and low-density lipoprotein cholesterol level(P<0.05),whereas high-density lipoprotein cholesterol was higher than the high-fat diet control group.Treatment with 300 mg/kg BW/day Oroxylum indicum fruit extract reduced the pathological lesion and prevented fat accumulation in the kidney and liver.Conclusions:Oroxylum indicum fruit extract has hypolipidemic effect in hyperlipidemic mice,and the active ingredients of Oroxylum indicum fruit extract,both flavonoids and volatile oils,should be further explored as an antihyperlipidemic agent.

文摘Bioassay-guided fractionation of an ethanolic extract of Ochrosia borbonica led to the isolation of two known pyridocarbazole alkaloids,ellipticine(1)and 9-methoxyellipticine(2),and six known monoterpenoid indole alkaloids(3-8).Lipid-lowering assay in 3 T3-L1 cell model revealed that 1 and 2 could significantly inhibit the lipid droplet formation(EC50(28)0.41 and 0.92μmol·L^–1,respectively)and lower triglyceride levels by 50%-60%at the concentration of 1μmol·L^–1,being more potent than the positive drug luteolin(EC50(28)2.63μmol·L–^1).A mechanistic study indicated that 1 and 2 could intercalate into supercoiled DNA,which consequently inhibited the mitotic clonal expansion of 3 T3-L1 cells at the early differentiation phase,leading to the retardance of following adipogenesis and lipogenesis.These findings suggest that 1 and 2 may serve as promising leads for further d evelopment of anti-obesity drugs.
文摘Statins have been shown to be effective in reducing cardiovascular events.Their magnitude of benefits has been proportionate to the reduction in low-density lipoprotein cholesterol(LDL-c).Intensive lipid-lowering therapies using ezetimibe and more recently proprotein convertase subtilisin kexin 9 inhibitors have further improved clinical outcomes.Unselective application of these treatments is undesirable and unaffordable and,therefore,has been guided by LDL-c level.Nonetheless,the residual risk in the post-statin era is markedly heterogeneous,including thrombosis and inflammation risks.Moreover,the lipoprotein related risk is increasingly recognised to be related to other non-LDL-c markers such as Lp(a).Emerging data show that intensive lipid-lowering therapy produce larger absolute risk reduction in patients with polyvascular disease,post coronary artery bypass graft and diabetes.Notably,these clinical entities share similar phenotype of large burden of atherosclerotic plaques.Novel plaque imaging may aid decision making by identifying patients with propensity to develop lipid rich plagues at multi-vascular sites.Those patients may be suitable candidates for intensive lipid lowering treatment.

文摘Swietenia macrophylla King,a medicine food homology,has garnered attention for the hypoglycemic and hypolipidemic activities of its fruit in the improvement of metabolic dysfunction-associated steatotic liver disease(MASLD),yet the glucolipid regulating properties of its leaf remains unexplored.The study sought to examine the pharmacological mechanisms underlying the lipid-lowering effects of Swietenia macrophylla King leaf extract(SLE)and its active constituent senegalension B(one of 31 limonoids in SLE).Glucolipid regulation by SLE and active constituent was evaluated through cellular triglyceride content and peripheral glucose levels in primary mouse hepatocytes(PMHs),SLE dose-dependently reduced lipid accumulation in the range of 23.65±3.41%to 37.39±2.50%,validated by Oil Red O staining.Network pharmacology and RNA sequencing identified SREBP-1c/FASN axis as the key mechanism by which SLE improved lipid accumulation in PMHs,consistent with sen-egalension B.RT-qPCR and Western blot showed that SLE(40μg/mL)decreased the lipid synthesis regulator SREBP-1c mRNA and protein levels by 60.69±1.69%and 48.07±11.83%,respectively,whereas senegal-ension B(40μM)achieved 55.42±2.29%and 34.34±8.49%inhibition.Dual-luciferase reporter assays revealed that senegalension B suppressed SREBP-1c promoter activity in Hep G2 cells.Molecular docking sug-gested a potential interaction with SREBP1,consistent with molecular dynamics simulation comparing binding affinity and stability with LXRα,indicating that senegalension B may exert lipid-lowering activity by targeting key proteins involved in lipid synthesis,such as SREBP-1c.This study elucidated the mechanisms and potential of SLE and senegalension B in regulating MASLD through in vitro investigation,expanded the utilization of Swietenia macrophylla King resources,and provided a candidate plant-derived compound for dietary therapy.
文摘γ-Aminobutyric acid(GABA)has been shown to have many beneficial functions and has received widespread attention.To broaden the application of GABA-rich fermentation supernatant,this study investigated the lipid-lowering capacity of GABA-rich supernatant from fermented okara(FOS-G)in vitro.The results showed that FOS-G improved the oxidative stress in OA-induced HepG2 cells by reducing the content of reactive oxygen species(ROS)and malondialdehyde(MDA).Furthermore,FOS-G improved the lipid accumulation in cells by reducing total cholesterol(TC)and triglyceride(TG).The results of Western blot showed that FOS-G exerted an ameliorative effect by activating the Keap1/Nrf2/HO-1 pathway and AMPK/SREBP-1 pathway.In particular,adipogenesis was inhibited by activating AMPK phosphorylation.The results showed that the therapeutic properties of FOS-G were directly related to its GABA content.In summary,FOS-G has a lipid-lowering capacity and can be used as a functional food ingredient for improving hyperlipidemia and non-alcoholic fatty liver disease(NAFLD).

文摘The effects of traditional flame stewing(TFS),commercial pressure cooking(PC),and sous-vide cooking(SVC)on the texture of pork belly and the underlying mechanism were investigated.SVC treatment at a low temper-ature(60℃)achieved weaker oxidation of sulfhydryl groups,lowerα-helical loss,higher surface hydropho-bicity,and actomyosin dissociation,which reduced the shrinkage of myofibrils and loss of immobilized water,thus contributed to a tender meat.However,the protein aggregation predominated without actomyosin disso-ciation during PC treatment,causing the toughening of meat.TFS and PC intensified the atrophy of adipocytes and damage of cell membranes,which helped for the softening of adipose tissue and achieved 13.82%and 17.62%lipid loss,respectively,and contributed to a higher ratio of polyunsaturated fatty acids to saturated fatty acids(0.45-0.46)than SVC(0.34).Comparisons showed that TFS was a more suitable method to prepare cooked pork belly with tender and juicy texture,low lipid content,and high ratio of polyunsaturated fatty acids to saturated fatty acids.This study offered new insights into how cooking regimes affect the texture and lipid-lowering effects of stewed pork.
