ABSTRACT

Background: Dyslipidemia plays a very important role in the occurrence and development of cardiovascular disease (CVD). Genetic factors, including single nucleotide polymorphisms (SNPs), are one of the main risks of dyslipidemia. 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR) is not only the rate-limiting enzyme step of endogenous cholesterol production, but also the therapeutic target of statins. Methods: We investigated 405 Han Chinese and 373 Uyghur people who took statins for a period of time, recorded their blood lipid levels and baseline data before and after oral statin administration, and extracted DNA from each subject for SNP typing of HMGCR rs17671591 and rs3761740. The effects of HMGCR rs17671591 and rs3761740 on lipid levels and the effect of statins on lipid lowering in Han Chinese and Uyghur ethnic groups were studied. Results: In this study, for rs17671591, the CC vs. TT+CT model was significantly correlated with the level of LDL-C before oral statin in the Uyghur population, but there were no correlations between rs17671591 and the level of blood lipid before oral statin in the Han population. The CC vs. TT+CT and CT vs. CC+TT models were significantly correlated with the level of LDL-C after oral statin in the Uyghur population. There was no significant correlation between rs3761740 with blood lipids before and after oral statin in the Han population. For rs3761740, before oral statin, the CC vs. AA+CA model was significantly correlated with the level of LDL-C, and the CA vs. CC+AA model was significantly correlated with the level of total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), and non-high density lipoprotein cholesterol (HDL-C) in the Uyghur population. After oral statin, the CC vs. AA+CA and CA vs. CC+AA models were significantly correlated with the level of TC, LDL-C, and apolipoprotein (APOB), and the C vs. A model was significantly correlated with the level of TC, triglyceride (TG), LDL-C, and APOB in the Uyghur population. Particularly, the CT vs. CC+TT model of rs17671591 was significantly correlated with the changes of LDL-C after oral statin in the Uyghur population. In this study, we also explored the association of rs17671591 and rs3761740 with the rate of dyslipidemia as a reference. Conclusion: We found that HMGCR rs3761740 was correlated with the levels of TC, LDL-C, and non-HDL-C before and after oral statin in Uyghurs, but not with blood lipid levels in the Han population. In the Uyghur population, HMGCR rs17671591 was associated with the level of LDL-C before and after oral statin, and also affected the changes of LDL-C after oral statin.

ABSTRACT

Higher serum cholesterol levels have been associated with an increased risk of dry eye disease (DED). The relationship between statin (HMG-CoA reductase inhibitor) use and DED in patients with hyperlipidemia remains unclear. To investigate the association between statin use and the risk of DED in patients with hyperlipidemia, we conducted a population-based retrospective cohort study utilizing data from Taiwan's Longitudinal Generation Tracking Database. Patients were categorized into statin users and nonusers, with a 5-year follow-up period. The study identified patients with newly diagnosed hyperlipidemia, excluding those with prior DED diagnoses. Matching and adjustments for covariates resulted in 41,931 individuals in each group. Patients receiving statin therapy were compared with those unexposed. Cumulative exposure doses were also evaluated to assess dose-response relationships. The primary outcome was the incidence of DED diagnosed during the follow-up period. Cox proportional hazards regression models estimated the risk of DED, and conditional logistic regression analyzed the dose-response effect of statin exposure. Among 41,931 matched pairs, statin users exhibited a slightly increased risk of developing DED compared with nonusers (adjusted hazard ratio, 1.06; 95% CI, 1.02-1.11; p < 0.01). However, no dose-response relationship was observed between statin exposure and DED risk. Statin use among patients with hyperlipidemia is associated with a marginally higher risk of DED. These findings underscore the importance of regular eye examinations in this patient population to facilitate early detection and management of DED.

ABSTRACT

BACKGROUND AND AIMS: We previously reported that Oxy210, an oxysterol-based drug candidate, exhibits antifibrotic and anti-inflammatory properties. We also showed that, in mice, it ameliorates hepatic hallmarks of non-alcoholic steatohepatitis (NASH), including inflammation and fibrosis, and reduces adipose tissue inflammation. Here, we aim to investigate the effects of Oxy210 on atherosclerosis, an inflammatory disease of the large arteries that is linked to NASH in epidemiologic studies, shares many of the same risk factors, and is the major cause of mortality in people with NASH. METHODS: Oxy210 was studied in vivo in APOE*3-Leiden.CETP mice, a humanized mouse model for both NASH and atherosclerosis, in which symptoms are induced by consumption of a high fat, high cholesterol "Western" diet (WD). Oxy210 was also studied in vitro using two cell types that are important in atherogenesis: human aortic endothelial cells (HAECs) and macrophages treated with atherogenic and inflammatory agents. RESULTS: Oxy210 reduced atherosclerotic lesion formation by more than 50% in hyperlipidemic mice fed the WD for 16 weeks. This was accompanied by reduced plasma cholesterol levels and reduced macrophages in lesions. In HAECs and macrophages, Oxy210 reduced the expression of key inflammatory markers associated with atherosclerosis, including interleukin-1 beta (IL-1ß), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), chemokine (C-C motif) ligand 2 (CCL2), vascular cell adhesion molecule-1 (VCAM-1), and E-Selectin. In addition, cholesterol efflux was significantly enhanced in macrophages treated with Oxy210. CONCLUSIONS: These findings suggest that Oxy210 could be a drug candidate for targeting both NASH and atherosclerosis, as well as chronic inflammation associated with the manifestations of metabolic syndrome.

ABSTRACT

BACKGROUND: This study investigates the hypolipidemic effects of a mixed extract of Salvia miltiorrhiza and Paeonia lactiflora (USCP119) in HFD-fed hamsters and in vitro cellular models. METHODS: Over an 8-week period, HFD-fed hamsters were assigned to one of six groups: normal diet, HFD control, HFD with 50 mg/kg USCP119, HFD with 100 mg/kg USCP119, HFD with 50 mg/kg USCP119 twice daily (BID), and HFD with omega-3 fatty acids. Key outcomes assessed included body weight, serum triglycerides (TG), total cholesterol (TC), liver weight, hepatic TG levels, and epididymal fat. In cellular models, the impact of USCP119 on lipid accumulation and adipogenic markers was evaluated. RESULTS: USCP119 treatment at 50 mg/kg BID resulted in the lowest weight gain (15.5%) and the most significant reductions in serum TG and hepatic TG levels compared to the HFD control. The 100 mg/kg dose also led to substantial reductions in serum TG and TC levels and notable decreases in low-density lipoprotein cholesterol. USCP119 at 50 mg/kg once daily reduced TG and TC levels but was less effective than the higher doses. In cellular models, USCP119 was non-toxic up to 400 µg/mL and effectively reduced lipid accumulation, modulated adipogenic markers, and enhanced AMPK signaling, improving lipid metabolism and insulin sensitivity. CONCLUSIONS: All USCP119 treatments demonstrated effectiveness in managing hyperlipidemia and related metabolic disorders, with variations in impact depending on the dosage. The ability of USCP119 to reduce fat accumulation, improve lipid profiles, and enhance insulin sensitivity highlights its potential as a valuable dietary supplement for addressing high-fat diet-induced hyperlipidemia and metabolic disturbances.

ABSTRACT

The simultaneous enhancement of lipophagy and mitochondrial biogenesis has emerged as a promising strategy for lipid lowering. The transcription factor EB (TFEB) exhibits a dual role, whereby it facilitates the degradation of lipid droplets (LDs) through the process of lipophagy while simultaneously stimulating mitochondrial biogenesis to support the utilization of lipophagy products. The purpose of this study was to explore the effect of astragaloside I (AS I) on hyperlipidemia and elucidate its underlying mechanism. AS I improved serum total cholesterol and triglyceride levels and reduced hepatic steatosis and lipid accumulation in db/db mice. AS I enhanced the fluorescence colocalization of LDs and autophagosomes and promoted the proteins and genes related to the autolysosome. Moreover, AS I increased the expression of mitochondrial biogenesis-related proteins and genes, indicating that AS I promoted lipophagy and mitochondrial biogenesis. Mechanistically, AS I inhibits the protein level of p-TFEB (ser211) expression and promotes TFEB nuclear translocation. The activation of TFEB by AS I was impeded upon the introduction of the mammalian target of rapamycin (mTOR) agonist MHY1485. The inhibition of p-mTOR by AS I and the activation of TFEB were no longer observed after administration of the Akt agonist SC-79, which indicated that AS I activated TFEB to promote lipophagy-dependent on the Akt/mTOR pathway and may be a potentially effective pharmaceutical and food additive for the treatment of hyperlipidemia.

ABSTRACT

BACKGROUND: The upper tract urothelial carcinoma (UTUC) risk associated with statin therapy in hyperlipidemic patients with chronic kidney disease (CKD) and end-stage kidney disease (ESKD) remains obscure. AIM: This retrospective cohort study investigated the UTUC risk for hyperlipidemic patients with CKD or ESKD associated with statin therapy. METHODS: From the national insurance claims data of Taiwan, we identified hyperlipidemic patients and established three pairs of statin users and non-users sub-cohorts matched by propensity scores: 401,490 pairs with normal kidney function, 37,734 pairs with CKD, and 6271 pairs with ESKD. Incidence rates and hazard ratio (HR) of UTUC were estimated, by the end of 2016, between statin and non-statin cohorts, and between hydrophilic statins users and lipophilic statins users. Time-dependent model estimated adjusted HR, and sub-distribution HR (sHR) accounting for the competing risk of deaths. RESULTS: The statin-users with ESKD were at increased UTUC risk (sHR 1.98; 95% confidence interval (CI), 1.28-3.06), significant for younger patients (40-64 years). The incidence was twofold greater in women than in men (31.8 versus 15.9 per 10,000 person-years). Receiving lipophilic statins was associated with increased UTUC risk in CKD and ESKD patients, while receiving hydrophilic statins was associated with increased UTUC risk in ESKD patients. CONCLUSIONS: Patients with ESKD receiving statin were at an increased UTUC risk, significant for younger group (<65 y/o). The positive associations between UTUC and statin persisted in both genders with ESKD, and in therapy with either lipophilic statins or hydrophilic statins. Statin users with ESKD deserve attention for UTUC prevention.

ABSTRACT

Pectin, a natural polysaccharide predominantly sourced from the cell walls of terrestrial plants, is widely regarded for its gelling, thickening, and stabilizing properties, which have extensive applications in the food, pharmaceutical, and biotechnological industries. This review discusses the mechanistic pathways by which pectin mediates its lipid-lowering properties, such as pectin's antioxidant activity, the modulation of gut microbiota, its anti-inflammatory properties, its capacity to bind bile acids and cholesterol, and its impact on the expression of genes associated with lipid metabolism. To enhance its hypolipidemic properties, chemical, physical, and enzymatic modification techniques are explored. Additionally, the synergistic effects of pectin in combination with other bioactive compounds such as phytosterols and polyphenols, as well as its potential in nanocarrier-mediated delivery systems for lipid-lowering agents, are highlighted. The review also conducts a critical analysis of the safety and regulatory considerations associated with pectin use, emphasizing the necessity for comprehensive toxicological evaluations and adherence to regulatory standards. This paper underscores the growing potential of pectin not only as a dietary fiber but also as a multifaceted agent for ameliorating hyperlipidemia, catalyzing a shift toward more targeted and efficacious lipid-lowering strategies.

ABSTRACT

Laminaria digitata is a high-quality seaweed resource that is widely cultured and has good application prospects. In this study, Laminaria digitata fucoidan (LF) was extracted from Laminaria digitata, and purified using DEAE-Sepharose Fast Flow gel column to obtain four different grades. Among those, LF4 (Mw:165 kDa), mainly composed of fucose(56.80 %), had the highest total sugar (66.91 %) and sulfate (17.07 %) content. FT-RT and NMR results showed that LF4 was mainly composed of galactosylated galactofucose, and has a sulfate group attached to fucose C4. With the animal experimentation, it was revealed that hyperlipidaemic mice had significantly higher levels of TC (5.52 mmol/L), TG (2.28 mmol/L) and LDL-C (5.12 mmol/L) and significantly lower levels of HDL-C (2 mmol/L). However, LF had the efficacy in modulating the lipid metabolism disturbances induced by hyperlipidemia, as well as the ability to regulate cholesterol transport in serum. Moreover, it regulated AMPK/ACC, PPAR-α/LAXRa, Nrf2/Nqo1, TLR4/NF-κB signaling pathway genes and proteins expression in the liver. In addition, it promoted the production of beneficial short-chain fatty acids (SCFAs) while improving the composition and structure of gut microbiota, including balancing the abundance of Bacteroidota, Firmicutes, Muribaculaceae, Alloprevotella, Escherichia-Shigella, Prevotella and NK4A136. The results clearly indicated that LF4 could significantly ameliorate hyperlipidemia, suggesting its prospective application as a functional food.

ABSTRACT

Obesity and hyperlipidemia have become major disorders predominantly causing prevailing cardiovascular diseases and ultimately death. The prolonged use of anti-obesity drugs and statins for reducing obesity and blood lipid levels is leading toward adverse effects of kidneys and muscles, specifically rhabdomyolysis. The objective of this study is to evaluate potential of seeds of Ficus carica against hyperlipidemia. Various extracts and isolated compounds from fig seeds were analyzed and evaluated for their anti-hyperlipidemic potential. Methanol extract and its ethyl acetate fraction showed maximum pancreatic lipase inhibition of 61.93% and 86.45% in comparison to reference drug Orlistat. Four compounds isolated by HPLC-PDA technique were determined as Gallic acid, Catechin, Epicatechin, and Quercetin also showed strong potential to inhibit enzyme pancreatic lipase comparable to Orlistat. These isolated compounds were further analyzed for molecular docking and MM-GBSA studies. Three ligands, namely Quercetin, Epicatechin, and Catechin were found more effective against pancreatic lipase as these possessed docking scores (-9.881, -9.741, -9.410) higher to that of the reference ligand Orlistat (-5.273). The binding free energies of these compounds were -55.03, -56.54, and 60.35 kcal/mol, respectively. The results have shown that Quercetin has the highest binding affinity correlating with the highest inhibition of pancreatic lipase enzyme 1LPB. Hence, it is suggested that seeds of F. carica have promising anti-hyperlipidemic potential and foremost in reducing obesity.

ABSTRACT

Pinus koraiensis (PK) leaf extract, derived from Korean pine byproducts, holds promise for alleviating postprandial hyperlipidemia. In this study, we investigated the potential of PK leaf extract for modulating postprandial hyperlipidemia in adults with normal or borderline fasting triglyceride levels. In a randomized, double-blind, parallel design, 70 subjects were randomly assigned to either the placebo or PK group for 4 weeks. After 4 weeks of consuming PK leaf extract, the results indicated a trend toward decreased serum apolipoprotein B-100 (ApoB100) levels 2 h after a high-fat challenge. Furthermore, significant improvements were observed in the incremental area under the curve (iAUC) at 0-4 h and 2-4 h compared to baseline, particularly among individuals with a higher body weight (>61.35 kg) and daily caloric intake (>1276.5 kcal). Based on these findings, PK leaf extract may have beneficial effects on postprandial lipoprotein metabolism, especially among individuals with a relatively high body weight and caloric intake.

ABSTRACT

Hyperlipidemia significantly contributes to the risk of developing cardiovascular diseases. However, about half of the patients do not adhere to their antihyperlipidemic medications, leading to healthcare costs and premature mortality. This study's objective was to determine the prevalence and associated factors of non-adherence to antihyperlipidemic medications. The study covered hypertensive patients (21,451) aged 21-75 years, presenting to the primary and secondary healthcare facilities across Pakistan (covering 21 divisions) from January 2022 to April 2023. The outcome intended was non-adherence to antihyperlipidemic medication, which was assessed by SEAMS and pill-counting methods (non-adherence < 80%). The study found overall non-adherence to antihyperlipidemic medication of 60.6% across Pakistan, with the highest non-adherence rates found in Azad Jammu and Kashmir (71.9%) and the lowest in Islamabad (47.7%). Multivariable logistic regression analysis revealed that female, no health card (Sehat Sahulat Program government insurance), < 5 years of illness, < 5 daily medications, and dose frequency of twice daily revealed a positively significant association with non-adherence. While monthly income 51,000-100,000, graduation level of education, Muhajir, and hyperlipidemia with one comorbid condition had a significant negative association with the non-adherence. Antihyperlipidemic non-adherence is a multifaceted, multifactorial, profound problem requiring a multipronged approach.

ABSTRACT

Monascus has the ability to produce secondary metabolites, such as monacolin K (MK), known for its physiological functions, including lipid-lowering effects. Widely utilized in industries such as health food and medicine, MK is a significant compound derived from Monascus. Quinoa, recognized by the Food and Agriculture Organization of the United Nations as "the only plant food that can meet human basic nutritional needs by itself", possesses dual advantages of high nutritional value and medicinal food homology. This study employed animal experiments to investigate the hypolipidemic activity of Monascus-fermented quinoa (MFQ) and explored the molecular mechanism underlying the lipid-lowering effect of MFQ on hyperlipidemic mice through transcriptomic and metabolomic analyses. The results demonstrated that high-dose MFQ intervention (1600 mg kg-1 d-1) effectively decreased weight gain in hyperlipidemic mice without significant changes in cardiac index, renal index, or spleen index. Moreover, hepatic steatosis in mice was significantly improved. Serum levels of total cholesterol, triglycerides, and low-density lipoprotein cholesterol were markedly reduced, demonstrating that the lipid-lowering effect of MFQ was comparable to the drug control lovastatin. Conversely, both low-dose MFQ (400 mg kg-1 d-1) and unfermented quinoa exhibited no significant lipid-lowering effect. Integrated analysis of the transcriptome and metabolome suggested that MFQ may regulate amino acid levels in hyperlipidemic mice by influencing metabolic pathways such as phenylalanine, tyrosine, and tryptophan metabolism. This regulation alleviates hyperlipidemia induced by a high-fat diet, resulting in a significant reduction in blood lipid levels in mice.

ABSTRACT

Hyperlipidemia is associated with intestinal barrier dysfunction and gut microbiota dysbiosis. Here, we aimed at investigating whether epicatechin (EC) and ß-glucan (BG) from whole highland barley grain alleviated hyperlipidemia associated with ameliorating intestinal barrier dysfunction and modulating gut microbiota dysbiosis in high-fat-diet-induced mice. It was observed that EC and BG significantly improved serum lipid disorders and up-regulated expression of PPARα protein and genes. Supplementation of EC and BG attenuated intestinal barrier dysfunction via promoting goblet cells proliferation and tight junctions. Supplementation of EC and BG prevented high fat diet-induced gut microbiota dysbiosis via modulating the relative abundance of Ruminococcaceae, Lactobacillus, Desulfovibrio, Lactococcus, Allobaculum and Akkermansia, and the improving of short chain fatty acid contents. Notably, combination of EC and BG showed synergistic effect on activating PPARα expression, improving colonic physical barrier dysfunction and the relative abundance of Lactobacillus and Desulfovibrio, which may help explain the effect of whole grain highland barley on alleviating hyperlipidemia.

ABSTRACT

Hyperlipidemia, an elevated level of cholesterol and/or triglycerides, has become a major public health problem worldwide. Although drugs intervention is effective in treating hyperlipidemia, most of them have adverse side effects. Peptides from natural plants with high anti-hyperlipidemic activity and a strong safety profile have emerged as promising candidates to prevent and ameliorate hyperlipidemia. This review summarizes the recent advances in plant-derived anti-hyperlipidemic peptides in terms of their sources, production, purification, identification, and activity evaluation. The focus is extended to their potential anti-hyperlipidemic mechanisms and structure-function relationships. Bioactive peptides derived from various plant sources, especially peptides containing hydrophobic and/or acidic amino acids, have shown remarkable effects in hyperlipidemic treatment. Their anti-hyperlipidemic effects are mediated by various mechanisms, including regulation of cholesterol metabolism and triglyceride metabolism, inhibition of inflammation-related metabolic syndrome, and modulation of the gut microbiota. Further evaluation of the stability, bioavailability, and clinical efficacy of these peptides is recommended.

ABSTRACT

BACKGROUND: Hyperlipidemia is one of the main causes of aggravated hepatic ischemia-reperfusion injury (IRI). Simvastatin (SIM), a lipid-lowering drug, has been shown to effectively alleviate IRI caused by hyperlipidemia. However, the regulatory mechanism by which SIM alleviates hyperlipidemia-induced hepatic IRI is still not clear. This study aims to explore the potential mechanisms of SIM in inhibiting hyperlipidemia-induced hepatic IRI, providing new therapeutic strategies for the alleviation of hepatic IRI. METHODS: An animal model of hyperlipidemia was induced by feeding mice a high-fat diet for 8 weeks. Subsequently, a hepatic IRI animal model of hyperlipidemia was established by occluding the hepatic artery and portal vein for one hour, followed by reperfusion for 6 or 12 h. Enzyme linked immunosorbent assay, Western blotting, hematoxylin-eosin (H&E) staining, immunohistochemistry, immunofluorescence, and Terminal-deoxynucleoitidyl Transferase Mediated Nick End Labeling assay, were used to evaluate liver injury, neutrophil extracellular traps (NETs) formation, and related molecular mechanisms. RESULTS: Hepatic IRI was accelerated by hyperlipidemia, which enhanced the expression of oxidized low-density lipoprotein (oxLDL) and Macrophage-1antigen (Mac-1), leading to the promotion of NETs formation and apoptosis of liver cells. The administration of simvastatin reduced the levels of oxLDL and Mac-1, decreased the formation of NETs, and alleviated hepatic IRI induced by hyperlipidemia. CONCLUSIONS: Simvastatin reduced hyperlipidemia-induced hepatic IRI by inhibiting the formation of NETs through the regulation of the oxLDL/Mac-1 pathway.

ABSTRACT

The prognosis after heart transplantation continues to improve. Therefore, the prevention of chronic post-transplant sequelae, such as chronic kidney disease, allograft vasculopathy, and malignancies is becoming increasingly important. Everolimus, an inhibitor of the mammalian target of rapamycin (mTOR), is increasingly used for immunosuppression after heart transplantation. However, everolimus may cause a characteristic complex of adverse effects, including dyslipidemia. Currently there are no guidelines for the long-term screening and treatment of dyslipidemia in heart transplant recipients treated with everolimus. This article presents a clinical case of hypercholesterolemia that developed after the start of the everolimus treatment in a heart recipient. The patient was a 39-year-old man who underwent orthotopic heart transplantation for ischemic cardiomyopathy in 2012 (at the age of 27). In 2019, the patient's immunosuppressive therapy was converted from mycophenolate mofetil to everolimus due to the development of cardiac allograft vasculopathy. The change in the immunosuppressive therapy was associated with increases in total cholesterol and low-density lipoprotein cholesterol, which were not reversed with a combined lipid-lowering therapy (maximum doses of rosuvastatin, ezetimibe, fenofibrate). A decrease in lipid levels was achieved with a blocker of hepatic proprotein convertase subtilisin/kexin type 9 synthesis at the level of microribonucleic acid (inclisiran). This case demonstrates the difficulties in correcting dyslipidemia in patients with cardiac allograft, since the treatment with the immunosuppressant everolimus worsens existing dyslipidemia. However, the combination lipid-lowering therapy, that affects various elements of the pathogenesis (specifically, the combined inhibition of hydroxymethylglutaryl-CoA reductase with a statin, cholesterol absorption from the small intestine with ezetimibe, and PCSK9 messenger RNA with inclisiran), provides an effective control of blood lipids and minimizing the adverse effects of immunosuppressive therapy, such as cardiac allograft vasculopathy.

ABSTRACT

BACKGROUND: This pilot study aimed to investigate medication nonadherence among Taiwanese patients with diabetes, hypertension, and hyperlipidemia using the Chinese version of the Two-Part Medication Nonadherence Scale (C-TPMNS) and the National Health Insurance (NHI) Medicloud system. The study revealed insights into the factors contributing to nonadherence and the implications for improving patient adherence to medications for chronic conditions. However, the small sample size limits the generalizability of the findings. Additionally, the study identified the need for further research with larger and more diverse samples to validate the preliminary findings. METHODS: The study conducted surveys individuals in central Taiwan who received three-high medications and those who returned expired medications from chain pharmacies. A structured questionnaire including the C-TPMNS was administered, and additional data on medical history and HbA1c, LDL, and blood pressure levels were collected from the NHI Medicloud system. Data analysis was performed using multiple ordered logistic regression and Wald test methods. Setting interpretation cutoff point to determine medication nonadherence. RESULTS: The study found that 25.8% of participants were non-adherent to prescribed medications. Non-adherent individuals had significantly higher systolic blood pressure (SBP ≥ 140 mmHg) than adherent participants. Non-adherence was also associated with factors such as lower education, single status, living alone, abnormal glucose postprandial concentration, and triglyceride levels. The C-TPMNS demonstrated good reliability (Cronbach's alpha = 0.816) and validity (area under the ROC curve = 0.72). CONCLUSION: The study highlighted the complexity of medication nonadherence with diverse determinants and emphasized the importance of tailored interventions. The findings underscored the need for region-specific research to comprehensively address medication nonadherence, especially focusing on adherence to medications for hypertension, hyperlipidemia, and diabetes. The study also identified the need for larger, more diverse studies to validate and expand upon the initial findings and emphasized the importance of pharmacist interventions and patient empowerment in managing chronic conditions and improving overall health outcomes.

ABSTRACT

Type 2 diabetes (T2D) is a chronic metabolic disorder characterized by hyperglycemia and dyslipidemia. The termite fungus comb is an integral component of nests of termites, which are a global pest. Termite fungus comb polysaccharides (TFCPs) have been identified to possess antioxidant, anti-aging, and immune-enhancing properties. However, their physicochemical characteristics and their role in fighting diabetes have not been previously reported. In the current study, TFCPs were isolated and structurally characterized. The yield of TFCPs was determined to be 2.76%, and it was found to be composed of a diverse array of polysaccharides with varying molecular weights. The hypoglycemic and hypolipidemic effects of TFCPs, as well as their potential mechanisms of action, were investigated in a T2D mouse model. The results demonstrated that oral administration of TFCPs could alleviate fasting blood glucose levels, insulin resistance, hyperlipidemia, and the dysfunction of pancreatic islets in T2D mice. In terms of mechanisms, the TFCPs enhanced hepatic glycogenesis and glycolysis while inhibiting gluconeogenesis. Additionally, the TFCPs suppressed hepatic de novo lipogenesis and promoted fatty acid oxidation. Furthermore, the TFCPs altered the composition of the gut microbiota in the T2D mice, increasing the abundance of beneficial bacteria such as Allobaculum and Faecalibaculum, while reducing the levels of pathogens like Mailhella and Acetatifactor. Overall, these findings suggest that TFCPs may exert anti-diabetic effects by regulating hepatic glucose and lipid metabolism and the composition of the gut microbiota. These findings suggest that TFCPs can be used as a promising functional ingredient for the prevention and treatment of T2D.

ABSTRACT

BACKGROUND: Hyperlipidemia damages vascular wall and serves as a foundation for diseases such as atherosclerosis, hypertension and stiffness. The NOD-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome is implicated in vascular dysfunction associated with hyperlipidemia-induced vascular injury. Sodium tanshinone IIA sulfonate (STS), a well-established cardiovascular protective drug with recognized anti-inflammatory, antioxidant, and vasodilatory properties, is yet to be thoroughly investigated for its impact on vascular relaxant imbalance induced by hyperlipidemia. METHODS: In this study, we treated ApoE-knockout (ApoE-/-) mouse with STS and assessed the activation of the NLRP3 inflammasome, expression of MMP2/9, integrity of elastic fibers, and vascular constriction and relaxation. RESULTS: Our findings reveal that STS intervention effectively preserves elastic fibers, significantly restores aortic relaxation function in ApoE-/- mice, and reduces their excessive constriction. Furthermore, STS inhibits the phosphorylation of spleen tyrosine kinase (SYK), suppresses NLRP3 inflammasome activation, and reduces MMP2/9 expression. CONCLUSIONS: These results demonstrate that STS protects vascular relaxation against hyperlipidemia-induced damage through modulation of the SYK-NLRP3 inflammasome-MMP2/9 pathway. This research provides novel insights into the mechanisms underlying vascular relaxation impairment in a hyperlipidemic environment and uncovers a unique mechanism by which STS preserves vascular relaxation, offering valuable foundational research evidence for its clinical application in promoting vascular health.
