Various microbial species within the complex ecosystem of the microbiome have been shown to play important roles in disease. Identification of bioactive materials capable of altering the abundances of these species both safely and effectively is a major goal in microbiome research. Many traditional Chinese medicines (TCMs) have been reported to affect the composition of the gut microbiome. Here, we summarize studies that have used TCMs to alter the gut microbiome and discuss the response relationship between TCMs and gut microbial species. Methods: We searched the PubMed, Web of Science, and Knowledge Network databases using the terms “traditional Chinese medicine,” “gut microbiome,” and specific system disease names (endocrine, immune, nervous, cardiovascular, and digestive). Studies were excluded if irrelevant or if the experimental procedures were unclear. Results: TCMs have been reported to affect a wide range of gut microbial taxa spanning major phyla, including Firmicutes, Bacteroidetes, Proteobacteria, Verrucomicrobiota, Actinobacteria, and Fusobacteria. In all, 54 TCMs including compounds and extracts have been tested in rodents and 30 have been examined in human trials. Almost all studies have reported positive results in regulating the gut microbiome as well as modulating corresponding phenotypes, spanning diseases of the endocrine, immune, nervous, cardiovascular, and digestive systems. Gut species, including Akkermansia, Bacteroides, Fusobacterium, Faecalibacterium, and E. coli, were found to be regulated by 19 TCMs. A network was constructed to visualize the interactions between TCMs and these taxa. Conclusion: There exists a complex and close relationship between intestinal microflora and diseases. Sufficient experimental data and studies have proved that the imbalance of intestinal microflora affects health by mediating metabolism, immune regulation, inflammation and signal transduction. Many characteristic alterations of intestinal microflora are positively correlated with diseases, so intestinal microflora has become a potential risk index and treatment target for many diseases. Many TCMs affect the relative abundances of microbial species in the gut, and therefore may be useful for modulating the gut microbiome. This review provides a reference for prioritizing candidate TCMs from the enormous repertoire of such medicines to test which specific gut microbes are targeted.展开更多

Pharmacogenomics has been at the forefront of research into the impact of individual genetic background on drug response variability or drug toxicity, and recently the gut microbiome, which has also been called the second genome, has been recog- nized as an important player in this respect. Moreover, the microbiome is a very attractive target for improving drug efficacy and safety due to the opportunities to manipulate its composition. Pharmacomicrobiomics is an emerging field that investigates the interplay of microbiome variation and drugs response and disposi- tion （absorption, distribution, metabolism and excretion）. In this review, we provide a historical overview and examine current state-of-the-art knowledge on the complex interactions between gut microbiome, host and drugs. We argue that combining pharmacogenomics and pharmacomicrobiomics will provide an important foundation for making major advances in personalized medicine.展开更多

文摘Increased circulating branched-chain amino acids(BCAAs)have been involved in the pathogenesis of obesity and insulin resistance.However,evidence relating berberine(BBR),gut microbiota,BCAAs,and insulin resis⁃tance is limited.Here,we showed that BBR could effectively rectify steatohepatitis and glucose intolerance in high-fat diet(HFD)-fed mice.BBR reorganized gut microbiota populations under both the normal chow diet(NCD)and HFD.Particu⁃larly,BBR noticeably decreased the relative abundance of BCAA-producing bacteria,including order Clostridiales;fami⁃lies Streptococcaceae,Clostridiaceae,and Prevotellaceae;and genera Streptococcus and Prevotella.Compared with the HFD group,predictive metagenomics indicated a reduction in the proportion of gut microbiota genes involved in BCAA biosynthesis but the enrichment genes for BCAA degradation and transport by BBR treatment.Accordingly,the elevated serum BCAAs of HFD group were significantly decreased by BBR.Furthermore,the Western blotting results implied that BBR could promote the BCAA catabolism in the liver and epididymal white adipose tissues of HFD-fed mice by acti⁃vation of the multienzyme branched-chain α-ketoacid dehydrogenase complex,whereas by inhibition of the phosphoryla⁃tion state of BCKDHA(E1α subunit)and branched-chain α-ketoacid dehydrogenase kinase.The ex vivo assay further confirmed that BBR could increase BCAA catabolism in both AML12 hepatocytes and 3T3-L1 adipocytes.Finally,data from healthy subjects and diabetics confirmed that BBR could improve glycemic control and modulate circulating BCAAs.Besides,functional microbiomics integrated high-throughput microbial genomics,metabolomics and molecular biotechnology has also been successfully applied to reveal the anti-obesity mechanism of hydroxysafflor yellow A.

文摘Background: The human gut microbiome is an important target for disease treatment and prevention. Various microbial species within the complex ecosystem of the microbiome have been shown to play important roles in disease. Identification of bioactive materials capable of altering the abundances of these species both safely and effectively is a major goal in microbiome research. Many traditional Chinese medicines (TCMs) have been reported to affect the composition of the gut microbiome. Here, we summarize studies that have used TCMs to alter the gut microbiome and discuss the response relationship between TCMs and gut microbial species. Methods: We searched the PubMed, Web of Science, and Knowledge Network databases using the terms “traditional Chinese medicine,” “gut microbiome,” and specific system disease names (endocrine, immune, nervous, cardiovascular, and digestive). Studies were excluded if irrelevant or if the experimental procedures were unclear. Results: TCMs have been reported to affect a wide range of gut microbial taxa spanning major phyla, including Firmicutes, Bacteroidetes, Proteobacteria, Verrucomicrobiota, Actinobacteria, and Fusobacteria. In all, 54 TCMs including compounds and extracts have been tested in rodents and 30 have been examined in human trials. Almost all studies have reported positive results in regulating the gut microbiome as well as modulating corresponding phenotypes, spanning diseases of the endocrine, immune, nervous, cardiovascular, and digestive systems. Gut species, including Akkermansia, Bacteroides, Fusobacterium, Faecalibacterium, and E. coli, were found to be regulated by 19 TCMs. A network was constructed to visualize the interactions between TCMs and these taxa. Conclusion: There exists a complex and close relationship between intestinal microflora and diseases. Sufficient experimental data and studies have proved that the imbalance of intestinal microflora affects health by mediating metabolism, immune regulation, inflammation and signal transduction. Many characteristic alterations of intestinal microflora are positively correlated with diseases, so intestinal microflora has become a potential risk index and treatment target for many diseases. Many TCMs affect the relative abundances of microbial species in the gut, and therefore may be useful for modulating the gut microbiome. This review provides a reference for prioritizing candidate TCMs from the enormous repertoire of such medicines to test which specific gut microbes are targeted.
文摘Inter-individual heterogeneity in drug response is a serious problem that affects the patient＇s wellbeing and poses enormous clinical and financial burdens on a societal level. Pharmacogenomics has been at the forefront of research into the impact of individual genetic background on drug response variability or drug toxicity, and recently the gut microbiome, which has also been called the second genome, has been recog- nized as an important player in this respect. Moreover, the microbiome is a very attractive target for improving drug efficacy and safety due to the opportunities to manipulate its composition. Pharmacomicrobiomics is an emerging field that investigates the interplay of microbiome variation and drugs response and disposi- tion （absorption, distribution, metabolism and excretion）. In this review, we provide a historical overview and examine current state-of-the-art knowledge on the complex interactions between gut microbiome, host and drugs. We argue that combining pharmacogenomics and pharmacomicrobiomics will provide an important foundation for making major advances in personalized medicine.

文摘Background Sow longevity and reproductivity are essential in the modern swine industry.Although many studies have focused on the genetic and genomic factors for selection,little is known about the associations between the microbiome and sows with longevity in reproduction.Results In this study,we collected and sequenced rectal and vaginal swabs from 48 sows,nine of which completed up to four parities(U4P group),exhibiting reproductive longevity.We first identified predictors of sow longevity in the rectum(e.g.,Akkermansia)and vagina(e.g.,Lactobacillus)of the U4P group using RandomForest in the early breeding stage of the first parity.Interestingly,these bacteria in the U4P group showed decreased predicted KEGG gene abundance involved in the biosynthesis of amino acids.Then,we tracked the longitudinal changes of the micro-biome over four parities in the U4P sows.LEfSe analysis revealed parity-associated bacteria that existed in both the rectum and vagina(e.g.,Streptococcus in Parity 1,Lactobacillus in Parity 2,Veillonella in Parity 4).We also identi-fied patterns of bacterial change between the early breeding stage(d 0)and d 110,such as Streptococcus,which was decreased in all four parties.Furthermore,sows in the U4P group with longevity potential also showed better reproductive performance.Finally,we discovered bacterial predictors(e.g.,Prevotellaceae NK3B31 group)for the total number of piglets born throughout the four parities in both the rectum and vagina.Conclusions This study highlights how the rectal and vaginal microbiome in sows with longevity in reproduc-tion changes within four parities.The identification of parity-associated,pregnancy-related,and reproductive performance-correlated bacteria provides the foundation for targeted microbiome modulation to improve animal production.
文摘BACKGROUND Colorectal cancer is the third most common malignancy and the fourth leading cause of cancer-related deaths worldwide.Several studies have shown an association between gut microbiota and colorectal cancer.Gut microbiota is unique and can be influenced by geographic factors and habits.This study aimed to determine the diversity and composition of colonic mucosal microbiota in patients with and without colorectal cancer.AIM To determine the diversity and composition of colonic mucosal microbiota in patients with and without colorectal cancer in Indonesia.METHODS This case-control study included 59 subjects(35 colorectal cancer patients and 24 non-colorectal cancer patients indicated for colonoscopy at Dr.Cipto Mangunkusumo Gastrointestinal Endoscopy Center and Fatmawati Hospital.Microbiota examination was performed using 16S rRNA sequencing.Bioinformatics analysis was performed using the wf-metagenomics pipeline from EPI2Me-Labs(Oxford Nanopore Technologies platform).RESULTS Patients with colorectal cancer had a higher median index value on the Shannon index(3.28 vs 2.82,P>0.05)and a lower value on the Simpson index(0.050 vs 0.060,P>0.05).Significant differences in beta diversity were observed at the genus(P=0.002)and species levels(P=0.001).Firmicutes,Proteobacteria,Bacteroidetes,and Fusobacteria were the dominant phyla.The genera Bacteroides,Campylobacter,Peptostreptococcus,and Parvimonas were found more frequently in colorectal cancer,while Faecalibacterium,Haemophilus,and Phocaeicola were more frequently found in non-colorectal cancer.The relative abundance of Fusobacterium nucleatum,Bacteroides fragilis,Enterococcus faecalis,Campylobacter hominis,and Enterococcus faecalis species was significantly elevated in patients with colorectal cancer.Meanwhile,Faecalibacterium prausnitzii,Faecalibacterium duncaniae,and Prevotella copri were more commonly found in non-colorectal cancer.CONCLUSION Patients with colorectal cancer exhibit distinct differences in the composition and diversity of their colonic mucosal microbiota compared to those with non-colorectal cancer.This study was reviewed and approved by the Ethics Committee of Faculty of Medicine,Universitas Indonesia(No.KET-1517/UN2.F1/ETIK/PPM.00.02/2023).

文摘As a major contributor to methane production in agriculture,there is a need for a suitable methane inhibitor to reduce ruminant methane emissions and minimize the impact on the climate.This work aimed to explore the influence of cordycepin on rumen fermentation,gas production,microbiome and their metabolites.A total of 0.00,0.08,0.16,0.32,and 0.64 g L^(–1)cordycepin were added into fermentation bottles containing 2 g total mixed ration for in vitro ruminal fermentation,and then the gas produced and fermentation parameters were measured for each bottle.Samples from the 0 and 0.64 g L^(–1)cordycepin addition were selected for 16S rRNA gene sequencing and metabolome analysis.The result of this experiment indicated that the addition of cordycepin could linearly increase the concentration of total volatile fatty acid,ammonia nitrogen,the proportion of propionate,valerate,and isovalerate,and linearly reduce ruminal pH and methane,carbon dioxide,hydrogen and total gas production,as well as the methane proportion,carbon dioxide proportion and proportion of butyrate.In addition,there was a quadratic relationship between hydrogen and cordycepin addition.At the same time,the relative abundance of Succiniclasticum,Prevotella,Rikenellaceae_RC9_gut_group,NK4A214_group,Christensenellaceae_R_(7)_group,unclassified_F082,Veillonellaceae_UCG_001,Dasytricha,Ophryoscolex,Isotricha,unclassified_Eukaryota,Methanobrevibacter,and Piromyces decreased significantly after adding the maximum dose of cordycepin.In contrast,the relative abundance of Succinivibrio,unclassified_Succinivibrionaceae,Prevotellaceae_UCG_001,unclassified_Lachnospiraceae,Lachnospira,Succinivibrionaceae_UCG_002,Pseudobutyrivibrio,Entodinium,Polyplastron,unclassified_Methanomethylophilaceae,Methanosphaera,and Candidatus_Methanomethylophilus increased significantly.Metabolic pathways such as biosynthesis of unsaturated fatty acids and purine metabolism and metabolites such as arachidonic acid,adenine,and 2′-deoxyguanosine were also affected by the addition of cordycepin.Based on this,we conclude that cordycepin is an effective methane emission inhibitor that can change the rumen metabolites and fermentation parameters by influencing the rumen microbiome,thus regulating rumen methane production.This experiment may provide a potential theoretical reference for developing Cordyceps byproduct or additives containing cordycepin as methane inhibitors.

文摘Probiotic supplementation enhances the abundance of gutassociated Rhodobacteraceae species,critical symbionts contributing to the health and physiological fitness of Litopenaeus vannamei.Understanding the role of Rhodobacteraceae in shaping the shrimp gut microbiota is essential for optimizing probiotic application.This study investigated whether probiotics benefit shrimp health and fitness via the recruitment of Rhodobacteraceae commensals in the gut.Probiotic supplementation significantly enhanced feed conversion efficiency,digestive enzyme activity,and immune responses,thereby promoting shrimp growth.Additionally,probiotics induced pronounced shifts in gut microbial composition,enriched gut Rhodobacteraceae abundance,and reduced community variability,leading to a more stable gut microbiome.Network analysis revealed that the removal of Rhodobacteraceae nodes disrupted gut microbial connectivity more rapidly than the removal of nonRhodobacteraceae nodes,indicating a disproportionate role of Rhodobacteraceae in maintaining network stability.Probiotic supplementation facilitated the migration of Rhodobacteraceae taxa from the aquatic environment to the shrimp gut while reinforcing deterministic selection in gut microbiota assembly.Transcriptomic analysis revealed that up-regulation of amino acid metabolism and NF-κB signaling pathways was positively correlated with Rhodobacteraceae abundance.These findings demonstrate that probiotic supplementation enriches key Rhodobacteraceae taxa,stabilizes gut microbial networks,and enhances host digestive and immune functions,ultimately improving shrimp growth performance.This study provides novel perspectives on the ecological and molecular mechanisms underlying the beneficial effects of probiotics on shrimp fitness.

文摘Artificial intelligence(AI)is driving a paradigm shift in gastroenterology and hepa-tology by delivering cutting-edge tools for disease screening,diagnosis,treatment,and prognostic management.Through deep learning,radiomics,and multimodal data integration,AI has achieved diagnostic parity with expert cli-nicians in endoscopic image analysis(e.g.,early gastric cancer detection,colorectal polyp identification)and non-invasive assessment of liver pathologies(e.g.,fibrosis staging,fatty liver typing)while demonstrating utility in personalized care scenarios such as predicting hepatocellular carcinoma recurrence and opti-mizing inflammatory bowel disease treatment responses.Despite these advance-ments challenges persist including limited model generalization due to frag-mented datasets,algorithmic limitations in rare conditions(e.g.,pediatric liver diseases)caused by insufficient training data,and unresolved ethical issues related to bias,accountability,and patient privacy.Mitigation strategies involve constructing standardized multicenter databases,validating AI tools through prospective trials,leveraging federated learning to address data scarcity,and de-veloping interpretable systems(e.g.,attention heatmap visualization)to enhance clinical trust.Integrating generative AI,digital twin technologies,and establishing unified ethical/regulatory frameworks will accelerate AI adoption in primary care and foster equitable healthcare access while interdisciplinary collaboration and evidence-based implementation remain critical for realizing AI’s potential to redefine precision care for digestive disorders,improve global health outcomes,and reshape healthcare equity.

文摘PURPOSE:To investigate the differences in gut microbial characteristics between two traditional Chinese syndromes of premature ovarian insufficiency(POI).METHODS:Forty women with POI were recruited from the Department of Traditional Chinese Medicine at Shenzhen Maternity and Child Healthcare Hospital between June and December 2020.Women with POI were divided into the kidney deficiency and blood stasis syndrome(SDBS)and Qi and blood deficiency syndrome(QBDS)groups.Gut microbial community profiles were analyzed by 16S rRNA gene sequencing using an Illumina Mi Seq system.A retrospective study comparing hormone levels and gut microbiota information was performed between the SDBS and QBDS groups.RESULTS:Compared with the QBDS group,the serum levels of estradiol(E2)and anti-Müllerian hormone(AMH)were significantly decreased in the SDBS group.The quantities of Adlercreutzia,Eggerthella,Klebsiella,and Paraprevotella significantly increased in the SDBS group,whereas Lactobacillus decreased significantly.Moreover,alterations in the microbiome in the SDBS and QBDS groups were closely related to the levels of E2 and AMH.The area under the receiver operating characteristic curve for the classification of the two syndromes by the gut microbiome was 0.71.CONCLUSIONS:There were significant differences in the dominant microbiota between the SDBS and QBDS groups,and the change in Proteobacteria in the QBDS group was more significant.The characteristics of gut microbiota help us differentiate between the SDBS and QBDS groups,which may provide a basis for the objectification of TCM syndrome types.
文摘This article comments on the work by Soresi and Giannitrapani.The authors have stated that one of the most novel and promising treatments for metabolic dysfunction-associated steatotic liver disease(MASLD)is the use of glucagon-like peptide 1 receptor agonists,especially when used in combination therapy.However,despite their notable efficacy,these drugs were not initially designed to target MASLD directly.In a groundbreaking development,the Food and Drug Administration has recently approved resmetirom,the first treatment specifically aimed at reducing liver fibrosis in metabolic-associated steatohepatitis.Resmetirom,an orally administered,liver-directed thyroid hormone beta-selective agonist,acts directly on intrahepatic pathways,enhancing its therapeutic potential and marking the beginning of a new era in the treatment of MASLD.Furthermore,the integration of lifestyle modifications into liver disease management is an essential component that should be considered and reinforced.By incorporating dietary changes and regular physical exercise into treatment,patients may achieve improved outcomes,reducing the need for pharmacological interventions and/or improving treatment efficacy.As a complement to medical therapies,lifestyle factors should not be overlooked in the broader strategy for managing MASLD.

文摘OBJECTIVE:To evaluate the effect of Fuzi Lizhong decoction(附子理中汤)on intestinal flora,serum inflammatory factors,and hypoxia inducible factor-1α(HIF-1α)in patients with colorectal cancer associated with spleen and kidney Yang deficiency.METHODS:A total of 100 patients diagnosed with advanced colorectal cancer were randomly divided into two groups:a control group(CON,50)and a Traditional Chinese Medicine(TCM)group(n=50).The control group received treatment with the Capecitabine+Oxaliplatin(CAPEOX)regimen,while the TCM group received the same regimen along with Fuzi Lizhong decoction for six weeks.Changes in intestinal flora were assessed before and after six weeks in both groups.Serum markers,including HIF-1α,vascular endothelial growth factor(VEGF),interleukin-6(IL-6),and tumor necrosis factor-alpha(TNF-α),were measured using enzyme-linked immunosorbent assay.Adverse reactions,clinical efficacy,and TCM syndrome efficacy were also monitored.RESULTS:After six weeks,the levels of Lactobacillus and Bifidobacterium were significantly higher,while the levels of Enterobacter and Enterococcus were significantly lower in the TCM group compared to the control group(P<0.05).Serum levels of HIF-1α,VEGF,IL-6,and TNF-αwere also significantly reduced in the TCM group compared to the control group(P<0.05).Additionally,the incidence of adverse reactions was lower,and the clinical efficacy was higher in the TCM group compared to the control group(P<0.05).CONCLUSION:Fuzi Lizhong decoction effectively improves intestinal microbiota composition,reduces inflammatory factors and HIF-1αexpression,alleviates chemotherapy-related adverse reactions,enhances clinical efficacy,and may inhibit tumor growth in patients with colorectal cancer.
文摘Extensive research has investigated the etiology of Crohn’s disease(CD),encompassing genetic predisposition,lifestyle factors,and environmental triggers.Recently,the gut microbiome,recognized as the human body’s second-largest gene pool,has garnered significant attention for its crucial role in the patho-genesis of CD.This paper investigates the mechanisms underlying CD,focusing on the role of‘creeping fat’in disease progression and exploring emerging therapeutic strategies,including fecal microbiota transplantation,enteral nutri-tion,and therapeutic diets.Creeping fat has been identified as a unique patho-logical feature of CD and has recently been found to be associated with dysbiosis of the gut microbiome.We characterize this dysbiotic state by identi-fying key microbiome-bacteria,fungi,viruses,and archaea,and their contributions to CD pathogenesis.Additionally,this paper reviews contemporary therapies,empha-sizing the potential of biological therapies like fecal microbiota transplantation and dietary interventions.By elucidating the complex interactions between host-microbiome dynamics and CD pathology,this article aims to advance our under-standing of the disease and guide the development of more effective therapeutic strategies for managing CD.

文摘The environments of tropical and subtropical coral reef regions(CRR)differ from each other;however,it is not known if these environmental differences influence coral polyp and skeleton microbiome composition.In this study,Coelastrea palauensis corals were collected from tropical and subtropical CRR in the South China Sea,and bacterial,archaeal,and fungal communities in polyps and skeletons were analyzed.Results showed that the microbial diversity and composition of C.palauensis significantly differed between the polyps and skeletons,and between the tropical and subtropical CRR.Regarding bacteria associated with corals,C.palauensis was mainly associated with bacteria closely related to the nitrogen cycle in the subtropical CRR.The relative abundances of Terasakiellaceae and Chlorobium in both coral polyps and skeletons in the subtropical CRR were higher than those in the tropical CRR.In the tropical CRR,C.palauensis was mainly associated with opportunistic pathogenic bacteria.The relative abundances of Tenacibaculum and Vibrio in coral polyps and skeletons in the tropical CRR were higher than those in the subtropical CRR.Regarding archaea associated with corals,polyps and skeletons of C.palauensis in both tropical and subtropical reef areas were dominated by n_Woesearchaeales,and the relative abundance of n_Woesearchaeales in skeletons is significantly higher than that in polyps.In addition,the relative abundances of n_Woesearchaeales in polyps and skeletons in the subtropical CRR were significantly higher than those in the tropical CRR.Regarding fungi associated with corals,Ascomycota was dominant in polyps and skeletons in the subtropical CRR,while Sordariomycetes,Periconia,Cladosporium,and Aspergillus were dominant in polyps and skeletons in the tropical CRR.Besides,the diversity differences of coral-associated microorganisms were related to environmental factors such as nutrients and temperature that may affect the survival of coral-associated microorganisms.These results implied that corals may adjust the composition of microorganisms,conducive the coral holobiont to better adapting the environment.Our research will be beneficial in understanding the differences and adaptations of coral polyp and skeletal microbiome.
文摘This study investigates the diversity of gut microbiota in Metaphire peguana,an earthworm species commonly found in agricultural areas of Thailand.Earthworms play a critical role in soil ecosystems by supporting nutrient cycling and breaking down organic matter.Understanding the microbial diversity in their gut is essential for exploring their ecological contributions.Using Next Generation Sequencing(NGS),we analyzed the mycobiome in the gut of M.peguana.Our findings revealed a high diversity of fungal species,primarily belonging to two major phyla:Ascomycota and Basidiomycota.Ascomycota was the most abundant phylum,comprising 40.1% of the total fungal species identified.A total of 33 distinct fungal species were identified,which underscores the richness of microbial life within the earthworm gut.This study successfully created the first genetic database of the microbial community in M.peguana,providing a foundation for future research in agricultural applications.The microbial species identified,particularly siderophoreproducing fungi,could have significant implications for improving soil fertility and promoting sustainable agricultural practices.The use of NGS technology has enabled comprehensive profiling of microbial communities,allowing for precise identification of fungi that may play essential roles in soil health.Furthermore,the study paves the way for future studies on the potential applications of earthworm gut microbiomes in biotechnology,especially in enhancing soil nutrient availability and plant growth.The findings of this research contribute to the broader understanding of the ecological roles of earthworms and their microbiomes in soil ecosystems.
