Hyperuricemia(HUA)is a vital risk factor for chronic kidney diseases(CKD)and development of functional foods capable of protecting CKD is of importance.This paper aimed to explore the amelioration effects and mechanism of Andrias davidianus bone peptides(ADBP)on HUA-induced kidney damage.In the present study,we generated the standard ADBP which contained high hydrophobic amino acid and low molecular peptide contents.In vitro results found that ADBP protected uric acid(UA)-induced HK-2 cells from damage by modulating urate transporters and antioxidant defense.In vivo results indicated that ADBP effectively ameliorated renal injury in HUA-induced CKD mice,evidenced by a remarkable decrease in serum UA,creatinine and blood urea nitrogen,improving kidney UA excretion,antioxidant defense and histological kidney deterioration.Metabolomic analysis highlighted 14 metabolites that could be selected as potential biomarkers and attributed to the amelioration effects of ADBP on CKD mice kidney dysfunction.Intriguingly,ADBP restored the gut microbiome homeostasis in CKD mice,especially with respect to the elevated helpful microbial abundance,and the decreased harmful bacterial abundance.This study demonstrated that ADBP displayed great nephroprotective effects,and has great promise as a food or functional food ingredient for the prevention and treatment of HUA-induced CKD. 展开更多

Hyperuricemia is a metabolic disorder caused by abnormal purine metabolism,resulting in abnormally high serum uric acid.In this study,a novel Levilactobacillus brevis PDD-5 isolated from salty vegetables was verified with the function of alleviating hyperuricemia.The relevant effects of L.brevis PDD-5 in lowering uric acid were analyzed by in vitro and in vivo experiments.The results showed that the L.brevis PDD-5 has(68.86±15.46)%of inosine uptake capacity and(95.75±3.30)%of guanosine uptake capacity in vitro.Oral administration of L.brevis PDD-5 to hyperuricemia rats reduced uric acid,creatinine,and urea nitrogen in serum,as well as decreased inosine and guanosine levels in the intestinal contents of rats.Analysis of relevant markers in the kidney by ELISA kits revealed that L.brevis PDD-5 alleviated oxidative stress and inflammation.Moreover,the gene expression of uric acid transporter 1(URAT1)and glucose transporter 9(GLUT9)was down-regulated,and the gene expression of organic anion transporter 1(OAT1)was up-regulated after treatment with L.brevis PDD-5.Western blot analysis showed that L.brevis PDD-5 alleviated hyperuricemia-induced kidney injury through the NLRP3 pathway.The se findings suggest that L.brevis PDD-5 can lower uric acid,repair kidney damage,and also has the potential to prevent uric acid nephropathy. 展开更多

Hyperuricemia,a metabolic disorder related to uric acid metabolism dysregulation,has become a common metabolic disease worldwide,due to changes in lifestyle and dietary structure.In recent years,owing to their high activity and few adverse effects,food-derived active peptides used as functional foods against hyperuricemia have attracted increasing attention.This article aims to focus on the challenge associated with peptide-specific preparation methods development,functional components identification,action mechanism(s)clarification,and bioavailability improvement.The current review proposed recent advances in producing the food-derived peptides with high anti-hyperuricemia activity by protein source screening and matched enzymatic hydrolysis condition adjusting,increased the knowledge about strategies to search antihyperuricemia peptides with definite structure,and emphasized the necessity of combining computer-aided approaches and activity evaluations.In addition,novel action mechanism mediated by gut microbiota was discussed,providing different insights from classical mechanism.Moreover,considering that little attention was paid previously on the structure-activity relationships of anti-hyperuricemia peptides,we collected the sequences from published studies and make a preliminary summary about the structure-activity relationships,which in turn provided guides for enzymatic hydrolysis optimization and bioavailability improvement.Hopefully,this article could promote the development,application and commercialization of food-derived anti-hyperuricemia peptides in the future. 展开更多

Hyperuricemia(HUA)is a condition associated with a high concentration of uric acid(UA)in the bloodstream and can cause gout and chronic kidney disease.The gut microbiota of patients with gout and HUA is significantly altered compared to that of healthy people.This article focused on the complex interconnection between alterations in the gut microbiota and the development of this disorder.Some studies have suggested that changes in the composition,diversity,and activity of microbes play a key role in establishing and progressing HUA and gout pathogenesis.Therefore,we discussed how the gut microbiota contributes to HUA through purine metabolism,UA excretion,and intestinal inflammatory responses.We examined specific changes in the composition of the gut microbiota associated with gout and HUA,highlighting key bacterial taxa and the metabolic pathways involved.Additionally,we discussed the effect of conventional gout treatments on the gut microbiota composition,along with emerging therapeutic approaches that target the gut microbiome,such as the use of probiotics and prebiotics.We also provided insights into a study regarding the gut microbiota as a possible novel therapeutic intervention for gout treatment and dysbiosis-related diagnosis. 展开更多

Hyperuricemia is a high-risk factor for the development of gout and renal fibrosis,but the adverse effects of hyperuricemia on the liver have been seriously neglected.This research investigated the ameliorating effect of Lacticaseibacillus rhamnosus Fmb14 on hyperuricemia induced liver dysfunction both in vitro and in vivo.Cell free extracts of high dose L.rhamnosus Fmb14 treatment reduced the death rate of HepG2 cell lines from 24.1%to 14.9%by inhibiting NLRP3 recruitment,which was mainly activated by reactive oxygen species release and mitochondrial membrane potential disorder.In purine dietary induced hyperuricemia(PDIH)mice model,liver oedema and pyroptosis were ameliorated after L.rhamnosus Fmb14 administration through downregulating the expression levels of NLRP3,caspase-1 and gasdermin-D from 1.61 to 0.86,3.15 to 1.01 and 5.63 to 2.02,respectively.L.rhamnosus Fmb14 administration restored mitochondrial inner membrane protein(MPV17)and connexin 43 from 2.83 and 0.73 to 0.80 and 0.98 respectively in PDIH mice,indicating that dysbiosis of mitochondrial membrane potential was restored in liver.Intriguingly,PDIH pyroptosis stimulates the process of apoptosis,which leads to severe leakage of hepatocytes,and both of pyroptosis and apoptosis were decreased after L.rhamnosus Fmb14 treatment.Therefore,L.rhamnosus Fmb14 is a promising biological resource to maintain homeostasis of the liver in hyperuricemia and the prevention of subsequent complications. 展开更多

Background:Simiaowan(SMW),a well-known traditional Chinese medicine,has been employed to treat hyperuricemia(HUA)and gout for centuries.However,the bioactive components and underlying mechanisms have not been elucidated.The objective of this study was to identify the active components and potential mechanisms of SMW by integrating pharmacological experimentation,serum pharmacochemistry,network pharmacology and molecular docking.Methods:HUA rats modelling by high-fat/high-sugar diet and potassium oxonate/adenine oral administration were used to evaluate the pharmacodynamic effects of SMW.UPLC-Q-Exactive-MS/MS was employed to detect the bioactive components present in SMW-containing serum.Network pharmacology and molecular docking were utilized to elucidate the potential targets and underlying mechanisms.Results:SMW effectively ameliorated HUA rats via the inhibition of uric acid(UA)production,promotion of UA excretion,improvement of lipid and glucose metabolic abnormalities,antioxidant,anti-inflammatory and anti-insulin resistance effects.A total of 73 compounds detected in SMW-containing serum were identified as potential active components,with alkaloids,flavonoids,organic acids,and terpenoids emerging as the primary active ingredients.Totally 203 corresponding targets were obtained as SMW anti-HUA/gout targets,which mainly participated in apoptosis,insulin resistance,TNF,PI3K-Akt,HIF-1,NF-κB,MAPK,IL-17 and TLR signaling pathways.Molecular docking indicated that active compounds(e.g.berberine,phellodendrine,quercetin,formononetin,ferulic acid)had superior binding abilities to the key targets(e.g.solute carrier family 22 member 12(URAT1),solute carrier family 22 member 6(OAT1),ATP-binding cassette sub-family G member 2(ABCG2),solute carrier family 2,facilitated glucose transporter member 9(GLUT9),xanthine dehydrogenase/oxidase(XDH),transcription factor p65(RELA),toll-like receptor 4(TLR4),prostaglandin G/H synthase 2(PTGS2),caspase-3(CASP3),insulin(INS)).Conclusion:SMW exerted regulatory influence over the disease network of HUA and gout through a multiplicity of components,targets,and pathways.Alkaloids,flavonoids,organic acids,and terpenoids were the primary active components,exerting anti-HUA/gout effects via antioxidant,anti-inflammatory,anti-insulin resistance,anti-apoptosis,inhibition of UA production,and promotion of UA excretion.This study revealed the active components and molecular mechanisms of SMW,providing insights into the development of natural products derived from SMW. 展开更多

Hyperuricemia is a critical threat to human health,and a high inosine diet can increase the prevalence of it.Lacticaseibacillus rhamnosus Fmb14 was isolated from traditional fermented Chinese yogurt,and its inosine degradation rate reached 36.3%at 109 CFU/mL for 24 h.LC-MS analysis revealed that high concentrations of inosine could activate compensatory metabolic pathways of L.rhamnosus Fmb14 to catalyse inosine as an energy source and produce intracellular folic acid and riboflavin.The contents of folic acid and riboflavin were 6.0 and 4.3 fold increased after inosine treatment in the cell-free extracts(CFE).L.rhamnosus Fmb14 CFE treatment ameliorates hyperuricemia through xanthine oxidase(XOD)inhibition and ATP-binding cassette subfamily G member 2(ABCG2)promotion,both of which are responsible for uric acid(UA)synthesis and secretion in HepG2 and Caco2 cells,respectively.The in vivo results showed that the serum UA level decreased from 236.28 to 149.28μmol/L after 8 weeks of oral administration of L.rhamnosus Fmb14 in inosine-induced hyperuricemia model mice.Our results revealed that L.rhamnosus Fmb14 has a potential as a biological therapeutic agent in hyperuricemia prevention. 展开更多

This study aimed to evaluate the alleviating effect of Chimonanthus nitens Oliv.leaves flavonoids(CLF)on hyperuricemia induced by potassium oxonate in mice.The results showed that CLF lowered the serum levels of uric acid(UA),creatinine and blood urea nitrogen,downregulated hepatic mRNA expressions of xanthine oxidase(XO),phosphate ribose pyrophosphate synthetase(PRPS)and adenosine deaminase(ADA)in hyperuricemia mice.In addition,CLF repaired renal injury by significantly down-regulating mRNA and protein expressions of renal UA reabsorption-related proteins and up-regulating the mRNA and protein expressions of UA secretory-related proteins.Finally,CLF inhibited UA synthesis and promoted UA excretion to alleviate hyperuricemia.Besides,CLF supplementation repaired the intestinal barrier function as demonstrated by significant increased mRNA levels of intestinal zonula occludens-1(ZO-1),Occludin,mucin 2(MUC2)and mucin 4(MUC4),as well as decreased mRNA levels of toll-like receptor 4(TLR4)and myeloid differentiation factor 88(MyD88)in mice.Further research showed that CLF treatment restored intestinal homeostasis mediated by improving the composition of gut microbiota and elevating the abundance of beneficial bacteria like Lactobacillus,Alistipes,Prevotellaceae_UCG-001 and Parasutterella.Overall,our findings revealed a novel function of CLF as a promising therapeutic candidate for the treatment of hyperuricemia. 展开更多

Hyperuricemia(HUA)mainly occurs because of purine metabolism disorders.We recently proposed that limonin from Simiao pill may have therapeutic effects on nitric oxide synthase 3(NOS3)that is related to HUA.Concurrently,our previous work employed a new method,structure-based multi-ligand molecular modeling,to identify potential agents from a herbal formula that may produce synergistic effects and may have the potential to develop combination drugs.Therefore,we employed multi-ligand modeling to seek compounds with potential synergistic effects with limonin against NOS3.We obtained 403 multi-ligand docking results between 403 compounds and the limonin-NOS3 complex(average affinity–8.297 kcal/mol).Then we selected the top 10 highest binding affinity compounds for virtual pharmacokinetic and toxicity screening and we found that only obacunone passed all filters.We further subjected obacunone,bound to limonin and NOS3,to molecular dynamics simulations.We found that the NOS3-limonin-obacunone complex was more stable than the NOS3-limonin complex,based on the root mean square deviation of backbone Cαatoms and root mean square fluctuation,which suggests that synergistic effects may exist between limonin and obacunone.Further cell and animal experimental research is required to verify our results. 展开更多

To investigate the possible targets and mechanisms of polyphenols in perilla in the treatment of hyperuricemia(HUA)Batman-TCM,TCMSP,PubMed,and CNKI databases were used to obtain the main components of perilla and component-related targets.HUA targets were collected through GeneCards and OMIM online platforms.The HUA target and the perilla component target were crossed to obtain a common target.Protein interaction networks were constructed using the STRING database,and the compound-target-pathway network was constructed by Cytoscape software.The GO and KEGG enrichment analysis was performed using the DAVID database.Molecular docking was used to verify the results.Thirteen potential active components,101 component targets,901 HUA-related targets,and 36 common targets were screened out.Through network topology analysis,core targets such as TP53,TNF,CASP3,and PPARG and active components such as luteolin,β-carotene,cyanidin,catechin,and linolenic acid ethyl ester were obtained.The topology analysis of the“compound-target-pathway”network showed that the polyphenolic compounds luteolin,cyanidin,and catechin were the main active components of the perilla in the treatment of HUA.This study showed that the treatment of HUA with perilla had the characteristics of a multi-component,multi-target,and multi-signal pathway,which provided a scientific basis for further study on the molecular mechanism of the treatment of HUA with the potential active components of perilla. 展开更多

Objective:This paper aims to study the clinical characteristics of patients with different types of primary hyperuricemia(HUA).Methods:Using a retrospective research method,200 patients with primary HUA in the hospital from June 2020 to January 2023 were selected as the research objects.Patients were grouped according to the detection results of 24-hour urinary uric acid excretion(UUE)and fractional excretion of uric acid(FEUA)(renal insufficiency type,renal overload type,mixed type,and other types).The general information of patients in the four groups(gender,age,body mass index,living habits,etc.),underlying diseases(hypertension,diabetes),blood test results[uric acid(UA),creatinine(Cre)],urine test results(24-hour urine UA,24-hour urine Cre)were summarized and the differences between the groups were analyzed.Results:The 200 cases of HUA patients were divided into 54.00%with renal insufficiency type,38.50%with mixed type,6.00%with renal overload type,and 1.50%with other types.The age of patients with mixed HUA was younger than that of patients with other types,renal overload type,and renal insufficiency type,and the difference was statistically significant(P<0.05).The UA level of patients with other types of HUA was lower than that of patients with mixed type HUA,and there was statistical significance(P<0.05).The Cre level of patients with mixed type HUA was lower than that of patients with renal insufficiency type and renal overload type,and the difference was statistically significant(P<0.05).The 24-hour urinary UA level in patients with renal insufficiency type HUA was lower than that in patients with renal overload type and mixed type HUA,and the difference was statistically significant(P<0.05).The 24-hour urinary Cre level of patients with other types of HUA was lower than that of patients with renal overload type and mixed HUA,the difference was statistically significant(P<0.05).The estimated glomerular filtration rate(eGFR)level of patients with other types of HUA was lower than that of patients with mixed type HUA,and the difference was statistically significant(P<0.05).There was no significant difference in the proportions of hypertension,diabetes,coronary heart disease,and urinary calculi among patients with renal insufficiency type,renal overload type,mixed type,and other types of HUA(P>0.05).Conclusion:The primary HUA patients are mainly of renal insufficiency type,followed by mixed type.There are significant differences in the clinical characteristics of patients with different types of HUA.Among them,patients with other types of HUA are the oldest and have the lowest uric acid levels.Patients with mixed HUA had the best renal function but the highest 24-hour urine creatinine level.This study can be used as a basis for rational selection of urate-lowering drugs for different HUA patients. 展开更多

Objective: To investigate the relationship between metabolic syndrome and hyperuricemia. Methods: A total of 2 374 subjects who received health examination in our hospital from Jan. 2004 to Dec. 2006 were enrolled in our study. Hyperuricemia is defined as ≥7 mg/dl (in men) or ≥6.0 mg/dl (in women). Metabolic syndrome was defined using AHA/NHLBI (American Heart Association/National Heart, Lung, and Blood Institute) criteria. Results: (1) The overall prevalence of hyperuricemia was 13.10%. The condition was more common in men than in women (19.07% vs 3.42%). (2) Among men, uric acid concentration is statistically significantly positively correlated with waist circumference, blood pressure, and triglyceride. Uric acid is negatively correlated with serum high-density lipoprotein-cholesterol (HDL-C). Uric acid concentration is most strongly correlated with serum triglyceride (r=0.379) and waist circumference (r=0.297). Among women, statistically significant positive correlations were noted for the serum uric acid concentrations with waist circumference, triglyceride and fasting plasma glucose. Serum triglyceride (r=0.329) and waist circumference (r=0.234) are most strongly correlated with uric acid concentrations. (3) Men with hyperuricemia had a 1.634-fold increased risk of metabolic syndrome as compared with those without hyperuricemia odds ratio (OR)=1.634, P=0.000. Women with hyperuricemia had a 1.626-fold increased risk of metabolic syndrome (OR=1.626, P=0.000) as compared with those without hyperuricemia. Conclusion: Hyperuricemia is prevalent among Chinese population. Additionally, serum uric acid is positively associated with metabolic syndrome. 展开更多

Objective To investigate the association of retinal vascular calibers with hyperuricemia in a middle‐aged and elderly population. Methods A cross‐sectional design was applied in this study and 869 participants aged ≥40 years from a high‐risk group for diabetes were recruited. All participants received the anthropometrical measurements and laboratory tests. Retinal arteriolar and venular caliber of the participants were measured with a semi‐automated system. Hyperuricemia was defined as a serum uric acid level 420 μmol/L in men and 360 μmol/L in women. Linear regression models were used to assess the association of hyperuricemia with retinal vascular calibers. These models were additionally adjusted for age, central obesity, hypertension, dyslipidemia, weekly activity, smoking status, and education. Results Among the 869 participants, 133 (15.3%) suffered from hyperuricemia. The crude mean serum uric acid level was 312.3 μmol/L (Standard Deviation 79.5); mean concentration was 355.0 μmol/L (SD 75.5) in male participants, and 288.0 μmol/L (SD 71.1) in female participants (age‐adjusted difference 58.1 μmol/L, 95% Confidence Internal 48.5, 67.6). After adjusting for additional covariates, male participants with hyperuricemia had 3.77 μm (95% CI ‐0.46, 8.00) smaller arteriolar caliber and 6.20 μm (95% CI 0.36, 12.04) larger venule than those without hyperuricemia; the corresponding numbers among female participants were 1.57 μm (95% CI ‐1.07, 4.21) for retinal arteriolar caliber and 2.28 μm (95% CI ‐1.72, 6.27) for retinal venular caliber. Conclusion Hyperuricemia was associated with smaller retinal arteriolar caliber and larger venular caliber mainly in male participants in this study. 展开更多

Objective To establish abdominal fat accumulation with hyperuricemia and hypercholesterolemia quail model fed with high fat diet. And then to investigate the pathological characteristics of this quail model. Methods Thirty Longcheng quails were randomly divided into two groups: control group and model group (n=15). The control group quails were fed with normal diet and model group quails were fed with high fat diet for 14 days. After a 12-hour overnight fast, liver and abdominal fat at euthanasia as well as serum were collected. The levels of serum uric acid, total cholesterol, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglyceride, free fatty acid (FFA), and blood glucose were assayed. The activity changes of adenosine deaminase (ADA), xanthine oxidase (XOD), lipoprotein lipase (LPL), hepatic lipase (HL), and fatty acid synthetase (FAS) were analyzed. Results Compared with control group, the abdominal fat content (0.74±0.63 vs. 1.36±0.65 g, P〈0.05) and abdominal fat index (0.44%±0.30% vs. 0.85%±0.30%, P〈0.01) as well as live lipid index (3.61%±0.65% vs. 11.33%±2.14%, P〈0.01) in model group significantly increased; the levels of serum uric acid (210.61±94,76 vs. 304.25±141.94 /amol/L, P〈0.05), total cholesterol (4.20±0.51 vs. 20.10±11.25 mmol/L, P〈0.01), LDL-C (1.16±0.29 vs. 10.78±6.48 mmol/L, P〈0.01), and FFA (0.39±0.14 vs. 0.55±0.15 mmol/L, P〈0.01) in model group significantly increased; HDL-C (5.85±0.95 vs. 4.14±2.03 mmol/L, P〈0.05) significantly decreased; the levels of triglyceride and blood glucose had no significant changes (P〉0.05); the activities of ADA (9.71±3.05 vs. 17.19±5.10 U/ml, P〈0.01) and XOD (10.58±6,88 vs. 19.22+9.44 U/L, P〈0.01) in model group significantly increased; and FAS, LPL, HL had no significant changes (P〉0.05). Conclusions High fat diet can induce abdominal fat accumulation with hyperuricemia and hypercholesterolemia quail model. The changes of uric acid and lipid metabolic enzyme activities may he the pathological mechanism of abdominal fat accumulation with hyperuricemia and hypercholesterolemia. 展开更多
