A novel strain of Levilactobacillus brevis PDD-5 isolated from salty vegetables has beneficial effects on hyperuricemia through anti-inflammation and improvement of kidney damage

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.

Andrias davidianus bone peptides alleviates hyperuricemia-induced kidney damage in vitro and in vivo

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.

Food-derived bio-functional peptides for the management of hyperuricemia and associated mechanism

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.

Lacticaseibacillus rhamnosus Fmb14 ameliorates hyperuricemia-induced hepatocyte pyroptosis via NLRP3 inflammasome cascade inhibition

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.

Elucidating the role of gut microbiota dysbiosis in hyperuricemia and gout:Insights and therapeutic strategies

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.

Leech Poecilobdella manillensis protein extract ameliorated hyperuricemia by restoring gut microbiota dysregulation and affecting serum metabolites

BACKGROUND Hyperuricemia(HUA)is a public health concern that needs to be solved urgently.The lyophilized powder of Poecilobdella manillensis has been shown to significantly alleviate HUA;however,its underlying metabolic regulation remains unclear.AIM To explore the underlying mechanisms of Poecilobdella manillensis in HUA based on modulation of the gut microbiota and host metabolism.METHODS A mouse model of rapid HUA was established using a high-purine diet and potassium oxonate injections.The mice received oral drugs or saline.Additionally,16S rRNA sequencing and ultra-high performance liquid chromatography with quadrupole time-of-flight mass spectrometry-based untargeted metabolomics were performed to identify changes in the microbiome and host metabolome,respectively.The levels of uric acid transporters and epithelial tight junction proteins in the renal and intestinal tissues were analyzed using an enzyme-linked immunosorbent assay.RESULTS The protein extract of Poecilobdella manillensis lyophilized powder(49 mg/kg)showed an enhanced anti-trioxypurine ability than that of allopurinol(5 mg/kg)(P<0.05).A total of nine bacterial genera were identified to be closely related to the anti-trioxypurine activity of Poecilobdella manillensis powder,which included the genera of Prevotella,Delftia,Dialister,Akkermansia,Lactococcus,Escherichia_Shigella,Enterococcus,and Bacteroides.Furthermore,22 metabolites in the serum were found to be closely related to the anti-trioxypurine activity of Poecilobdella manillensis powder,which correlated to the Kyoto Encyclopedia of Genes and Genomes pathways of cysteine and methionine metabolism,sphingolipid metabolism,galactose metabolism,and phenylalanine,tyrosine,and tryptophan biosynthesis.Correlation analysis found that changes in the gut microbiota were significantly related to these metabolites.CONCLUSION The proteins in Poecilobdella manillensis powder were effective for HUA.Mechanistically,they are associated with improvements in gut microbiota dysbiosis and the regulation of sphingolipid and galactose metabolism.

Effect of dapagliflozin on uric acid in patients with chronic heart failure and hyperuricemia

BACKGROUND Patients with chronic heart failure(CHF)frequently develop hyperuricemia,an elevated serum uric acid level,associated with adverse outcomes.Dapagliflozin,a sodium-glucose cotransporter-2 inhibitor,demonstrates reduction in cardiovascular mortality and hospitalization in patients with CHF and ejection fraction(HFrEF),irrespective of diabetes.However,dapagliflozin’s effect on the uric acid levels in patients with CHF and hyperuricemia remain unclear.AIM To investigate the effects of dapagliflozin on uric acid levels in CHF patients with hyperuricemia.METHODS We conducted a randomized,double-blind,placebo-controlled trial in 200 patients with CHF and hyperuricemia,with HFrEF and serum uric acid levels≥7 mg/dL(≥416μmol/L).The participants were randomly assigned to receive a daily dose of 10 mg dapagliflozin or placebo for 24 months.The primary endpoint was the change in serum uric acid level from baseline to 24 months.Secondary endpoints included changes in left ventricular ejection fraction(LVEF),Nterminal pro-B-type natriuretic peptide(NT-proBNP),and quality of life(QoL)scores,as well as the incidence of cardiovascular death and hospitalization for heart failure.RESULTS At 24 months,dapagliflozin significantly reduced serum uric acid levels by 1.2 mg/dL(71μmol/L)compared with placebo(95%CI:-1.5 to-0.9;P<0.001).Dapagliflozin also significantly improved LVEF by 3.5%(95%CI:2.1-4.9;P<0.001),NT-proBNP by 25%(95%CI:18-32;P<0.001),and QoL scores by 10 points(95%CI:7-13;P<0.001)and reduced the risk of cardiovascular death and hospitalization for heart failure by 35%(95%CI:15–50;P=0.002)compared with the placebo.Adverse events were similar between the two groups,except for a higher rate of genital infections in the dapagliflozin group(10%vs 2%,P=0.01).CONCLUSION Dapagliflozin significantly lowered serum uric acid levels and improved the clinical outcomes in patients with CHF and hyperuricemia.Therefore,dapagliflozin may be a useful therapeutic option for this high-risk population.

Ameliorative effect of Lacticaseibacillus rhamnosus Fmb14 from Chinese yogurt on hyperuricemia

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.

Hero Hua Mulan With a Thousand Faces:Why Chinese Stories Can Move the World?Evidence From a Global Cross-Cultural Interview Survey

While people from Western countries do not always understand of the underlying cultural values of most Chinese stories,the Hua Mulan story has gained significant recognition from Western audiences.Therefore,it would be quite beneficial if we could understand the key elements that have contributed to the success of the Hua Mulan story so that we can employ similar elements in other intercultural communication programs and promote the communication and dissemination of cultures between China and the rest of the world.According to the findings from the interviews of 6,130 respondents from 107 countries,we found that the Hua Mulan story gains global acceptance because it represents a story of“a hero with a thousand faces,”which embodies the integration of Chinese traditions and contemporary spirit through sharing a global meaning while responding to various culturally common challenges.Five key cultural value dimensions are responsible for this Chinese story’s cross-cultural affinity and influence,which helped it win recognition and empathy worldwide.The five key cultural value dimensions are loyalty and patriotism,the courage to take responsibility,compatibility of individualism and collectivism,respondence to the multicultural appeal,and hero growth.These dimensions are then generalized as the value identity orientation grounded in a Global Shared Meaning(GSM)in this study.

Chimonanthus nitens Oliv. leaves flavonoids alleviate hyperuricemia by regulating uric acid metabolism and intestinal homeostasis in mice

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.

Epidemiological characteristics of hyperuricemia in metabolic syndrome and its different components in the physical examination population

Objective:To explore the epidemiological characteristics of hyperuricemia(HUA)in the metabolic syndrome(MS)and its different components in the physical examination population.Methods:Subjects who underwent medical check-ups at a hospital health management center from June 2021 to March 2023 were included in the study.To analyze the prevalence of HUA in MS and its different components,further,stratify the study population by gender and assess the serum uric acid(SUA)levels and prevalence of HUA in people with different numbers of MS components and the combination of MS components with the highest prevalence of HUA in both sexes.Logistic regression was used to analyze the risk of HUA in people with different numbers of MS components.Result:A total of 66,520 individuals were enrolled in the study.SUA levels(t=-82.947,P<0.001)and HUA prevalence(χ^(2)=3421.632,P<0.001)were significantly higher in the MS group than in the Non-MS group.SUA levels and prevalence of HUA were significantly higher in abdominal obesity,hypertension,decreased HDL-C and evaluated TG than in normal subjects(P<0.001),while there were gender differences in SUA levels and HUA prevalence in diabetic patients,with significantly lower SUA levels and HUA prevalence in men with diabetes than in those with normal blood glucose,an opposite result in women.SUA levels and HUA prevalence gradually increased with the increasing number of MS components in women,whereas in men,such a trend was only observed in MS1-MS4.The combination of MS components with the highest prevalence of HUA was abdominal obesity+hypertension+decreased HDL-C+evaluated TG(54.35%)in men and abdominal obesity+hypertension+diabetes+decreased HDL-C+evaluated TG(41.46%)in women.Logistic regression analysis showed that after adjusting for gender,age and ethnicity,the risk of HUA increased with the number of MS components in women,while in men,the risk of HUA increased continuously from MS1-MS4.Further adjustment for BMI,elevated TC,elevated LDL-C,and coronary artery disease,the results remained consistent.Conclusion:MS and its components are risk factors for HUA in the physical examination population,with different combinations of MS components having different correlations with HUA,and the risk of developing HUA correlates with the number of abnormal MS components.
