Abstract
BACKGROUND Glycopeptide antibiotic vancomycin is a bactericidal antibiotic available for the infection to Staphylococcus aureus (SA), however, SA has a strong adaptive capacity and thereby acquires resistance to vancomycin. This study aims to illuminate the possible molecular mechanism of vancomycin resistance of SA based on the 16S rRNA sequencing data and microarray profiling data. METHODS 16S rRNA sequencing data of control samples and urinary tract infection samples were retrieved from the EMBL-EBI (European Molecular Biology Laboratory - European Bioinformatics Institute) database. Correlation of gut flora and clinical indicators was evaluated. The possible targets regulated by SA were predicted by microarray profiling and subjected to KEGG (Kyoto Encyclopedia of Genes and Genomes) enrichment analysis. CXCL10 gene knockout and overexpression were introduced to evaluate the effect of CXCL10 on the virulence of SA and the resistance to vancomycin. SA strains were co-cultured with urethral epithelial cells in vitro. The presence of SA virulence factors was detected using PCR. Biofilm formation of SA strains was assessed using the microtiter plate method. Furthermore, the antibiotic sensitivity of SA strains was evaluated through vancomycin testing. RESULTS Gut flora and its species abundance had significant difference between urinary tract infection and control samples. SA was significantly differentially expressed in urinary tract infection samples. Resistance of SA to vancomycin mainly linked to the D-alanine metabolism pathway. SA may participate in the occurrence of urinary tract infection by upregulating CXCL10. In addition, CXCL10 mainly affected the SA resistance to vancomycin through the TLR signaling pathway. In vitro experimental results further confirmed that the overexpression of CXCL10 in SA increased SA virulence and decreased its susceptibility to vancomycin. In vitro experimental validation demonstrated that the knockout of CXCL10 in urethral epithelial cells enhanced the sensitivity of Staphylococcus aureus (SA) to vancomycin. CONCLUSION SA upregulates the expression of CXCL10 in urethral epithelial cells, thereby activating the TLR signaling pathway and promoting resistance to glycopeptide antibiotics in SA.

Abstract
Microplastics (MPs), which are prevalent and increasingly accumulating in aquatic environments. Other pollutants coexist with MPs in the water, such as pesticides, and may be carried or transferred to aquatic organisms, posing unpredictable ecological risks. This study sought to assess the adsorption of lambda-cyhalothrin (LCT) by virgin and aged polyethylene MPs (VPE and APE, respectively), and to examine their influence on LCT's toxicity in zebrafish, specifically regarding acute toxicity, oxidative stress, gut microbiota and immunity. The adsorption results showed that VPE and APE could adsorb LCT, with adsorption capacities of 34.4 mg∙g-1 and 39.0 mg∙g-1, respectively. Compared with LCT exposure alone, VPE and APE increased the acute toxicity of LCT to zebrafish. Additionally, exposure to LCT and PE-MPs alone can induce oxidative stress in the zebrafish gut, while combined exposure can exacerbate the oxidative stress response and intensify intestinal lipid peroxidation. Moreover, exposure to LCT or PE-MPs alone promotes inflammation, and combined exposure leads to downregulation of the myd88-nf-κb related gene expression, thus impacting intestinal immunity. Furthermore, exposure to APE increased LCT toxicity to zebrafish more than VPE. Meanwhile, exposure to PE-MPs and LCT alone or in combination has the potential to affect gut microbiota function and alter the abundance and diversity of the zebrafish gut flora. Collectively, the presence of PE-MPs may affect the toxicity of pesticides in zebrafish. The findings emphasize the importance of studying the interaction between MPs and pesticides in the aquatic environment.

Abstract
Callicarpa nudiflora Hook (C. nudiflora) is an anti-inflammatory, antimicrobial, antioxidant, and hemostatic ethnomedicine. To date, little has been reported regarding the activity of C. nudiflora against ulcerative colitis (UC). In this study, we investigated the effect of a flavonoid extract of C. nudiflora on Dextran Sulfate Sodium (DSS)-induced ulcerative colitis in mice. Mice in the treatment group (CNLF+DSS group) and drug-only (CNLF group) groups were administered 400 mg/kg of flavonoid extract of C. nudiflora leaf (CNLF), and drinking water containing 2.5 % DSS was given to the model and treatment groups. The symptoms of colitis were detected, relevant indicators were verified, intestinal barrier function was assessed, and the contents of the cecum were analyzed for intestinal microorganisms. The results showed that CNLF significantly alleviated the clinical symptoms and histological morphology of colitis in mice, inhibited the increase in pro-inflammatory factors (TNF-α, IL-6, IL-1β, and IFN-γ), and increased the level of IL-10. The expression of NF-κB and MAPK inflammatory signal pathway-related proteins (p-p65, p-p38, p-ERK, p-JNK) was regulated. The expression of tight junction proteins (ZO-1, OCLDN, and CLDN1) was increased, while the content of D-LA, DAO, and LPS was decreased. In addition, 16S rRNA sequencing showed that CNLF restored the gut microbial composition, and increased the relative abundance of Prevotellaceae, Intestinimonas butyriciproducens, and Barnesiella_intestinihominis. In conclusion, CNLF alleviated colitis by suppressing inflammation levels, improving intestinal barrier integrity, and modulating the intestinal microbiota, and therefore has promising future applications in the treatment of UC.

Abstract
BACKGROUND Parkinson's disease (PD) is a neurodegenerative condition characterized by the progressive loss of dopaminergic neurons within the substantia nigra. Neuroinflammation plays a pivotal role in the pathogenesis of PD, involving the activation of microglia cells, heightened production of proinflammatory cytokines, and perturbations in the composition of the gut microbiota. Rubusoside (Ru), the principal steviol bisglucoside present in Rubus chingii var. suavissimus (S.K.Lee) L.T.Lu (Rosaceae), has been documented for its anti-inflammatory properties in diverse disease models. Nonetheless, there is an imperative need to comprehensively assess and elucidate the protective and anti-inflammatory attributes of Ru concerning PD, as well as to uncover the underlying mechanism involved. OBJECTIVE The aim of this study is to evaluate the neuroprotective and anti-inflammatory effects of Ru on PD and investigate its potential mechanisms associated with microbes. RESEARCH DESIGN AND METHODS We pre-treated mice and cell lines with Ru in order to simulate the progression of PD and the neuroinflammatory state. The mouse model was induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), SN4741 cells were induced by 1-methyl-4-phenylpyridine (mpp+), and BV-2 cells were induced by lipopolysaccharide (LPS). We assessed the impact of Ru on motor function, neuroinflammation, neuron apoptosis, the composition of gut microbes, and their metabolites. RESULTS Ru treatment reduces the release of pro-inflammatory mediators by inhibiting microglia activation. It also prevents neuronal apoptosis, thereby safeguarding dopaminergic neurons and ameliorating motor dysfunction. Furthermore, it induces alterations in the fecal microbiota composition and metabolites profile in PD mice. In vitro experiments have demonstrated that Ru inhibits neuronal apoptosis in SN4741 cells induced by mpp+, suppresses the production of pro-inflammatory mediators, and activates the c-Jun N-terminal kinase (JNK), mitogen-activated protein kinase (p38 MAPK), and nuclear factor kappa-B (NF-κB) signaling pathways. CONCLUSION Ru exhibits inhibitory effects on the MPTP-induced PD model by mitigating neuroinflammation and neuronal apoptosis while also inducing changes in the gut microbiota and metabolite composition.

Abstract
PURPOSE OF REVIEW The importance of the gut microbiome has received increasing attention in recent years. New literature has revealed significant associations between gut health and various orthopedic disorders, as well as the potential for interventions targeting the gut microbiome to prevent disease and improve musculoskeletal outcomes. We provide a broad overview of available literature discussing the links between the gut microbiome and pathogenesis and management of orthopedic disorders. RECENT FINDINGS Human and animal models have characterized the associations between gut microbiome dysregulation and diseases of the joints, spine, nerves, and muscle, as well as the physiology of bone formation and fracture healing. Interventions such as probiotic supplementation and fecal transplant have shown some promise in ameliorating the symptoms or slowing the progression of these disorders. We aim to aid discussions regarding optimization of patient outcomes in the field of orthopedic surgery by providing a narrative review of the available evidence-based literature involving gut microbiome dysregulation and its effects on orthopedic disease. In general, we believe that the gut microbiome is a viable target for interventions that can augment current management models and lead to significantly improved outcomes for patients under the care of orthopedic surgeons.

Abstract
BACKGROUND The pathogenesis of cardiac arrhythmias is multifaceted, encompassing genetic, environmental, hemodynamic, and various causative factors. Emerging evidence underscores a plausible connection between gut flora, serum metabolites, and specific types of arrhythmias. Recognizing the role of host genetics in shaping the microbiota, we employed two-sample Mendelian randomization analyses to investigate potential causal associations between gut flora, serum metabolites, and distinct arrhythmias. METHODS Mendelian randomization methods were deployed to ascertain causal relationships between 211 gut flora, 575 serum metabolites, and various types of arrhythmias. To ensure the reliability of the findings, five complementary Mendelian randomization methods, including inverse variance weighting methods, were employed. The robustness of the results was scrutinized through a battery of sensitivity analyses, incorporating the Cochran Q test, leave-one-out test, and MR-Egger intercept analysis. RESULTS Eighteen gut flora and twenty-six serum metabolites demonstrated associations with the risk of developing atrial fibrillation. Moreover, ten gut flora and fifty-two serum metabolites were linked to the risk of developing supraventricular tachycardia, while eight gut flora and twenty-five serum metabolites were associated with the risk of developing tachycardia. Additionally, six gut flora and twenty-one serum metabolites exhibited associations with the risk of developing bradycardia. CONCLUSION This study revealed the potential causal relationship that may exist between gut flora, serum metabolites and different cardiac arrhythmias and highlights the need for further exploration. This study provides new perspectives to enhance diagnostic and therapeutic strategies in the field of cardiac arrhythmias.

Abstract
Natural plant polysaccharides are macromolecular substances with a wide range of biological activities. They have a wide range of biological activities, especially play an important role in the treatment of inflammatory bowel disease. The molecular weight of polysaccharides, the composition of monosaccharides and the connection of glycosidic bonds will affect the therapeutic effect on inflammatory bowel disease. Traditional Chinese medicine plant polysaccharides and various types of plant polysaccharides reduce the levels of inflammatory cytokines IL-1β, IL-6, IL-8 and IL-17, increase the level of anti-inflammatory factor IL-10, regulate NF-κB signaling pathway, and NLRP3 inflammasome to relieve colitis. At the same time, they can play a protective role by regulating the balance of intestinal flora in mice with colitis and increasing the abundance of probiotics to promote the metabolism of polysaccharide metabolites SCFAs. This review summarizes the research on the treatment of inflammatory bowel disease by many natural plant polysaccharides, and provides a theoretical basis for the later treatment of polysaccharides on inflammatory bowel disease.

Abstract
Rheumatoid arthritis (RA) is more common in women, and many reports of sex differences have been reported in various aspects of RA. However, there has been a lack of specific research on women's gut flora. To assess the association between the gut flora and RA patients, this study combined the microbiome with metabolomics. Fecal samples from RA patients and healthy controls were collected for 16S rRNA sequencing. Nontargeted liquid chromatography-mass spectrometry was used to detect metabolites in fecal samples. We comprehensively used various analytical methods to reveal changes in intestinal flora and metabolites in female patients. The gut flora of RA patients was significantly different from that of healthy women. The abundance of Bacteroides, Megamonas and Oscillospira was higher in RA patients, while the abundance of Prevotella, Gemmiger and Roseburia was lower than that of healthy women. Gemmiger, Bilophila and Odoribacter represented large differences in microflora between RA and healthy women and could be used as potential microorganisms in the diagnosis. Fatty acid biosynthesis was significantly different between RA patients and healthy women in terms of metabolic pathways. There were different degrees of correlation between the gut flora and metabolites. Lys-Phe-Lys and heptadecasphin-4-enine can be used as potential markers for RA diagnosis. There was an extremely significant positive correlation between Megamonas, Dialister and rheumatoid factors, which was found for the first time. These findings indicated that alterations of these gut microbiome and metabolome may contribute to the diagnosis and treatment of RA patients.

Abstract
The function of the intestinal tract is critical to human health. Poria cocos is a widely used functional edible fungus in Asia and has been reported to modulate gastrointestinal function. However, the effects of polysaccharides, the main active constituents of Poria cocos, on the intestinal tract remains unclear and is the focus of the study. Poria cocos polysaccharides (PCP) were extracted, characterized, and administered to mice by gavage. The results show that PCP used in this study has a typical polysaccharide peak with a molecular weight of 11.583 kDa and is composed primarily of mannose, D-glucosamine hydrochloride, glucose, galactose, and fucose with a molar ratio of 15.308: 0.967: 28.723: 31.631: 23.371. The methylation results suggest that the PCP backbone may be t-Gal(p), 6-Gal(p) and 2,6-Gal(p). The effects of PCP on the mucosal barrier function of the mouse intestine (duodenum, jejunum, and ileum) were examined in terms of intestinal physiological status, physical barrier, biochemical barrier, immune barrier, and microbial barrier. The results showed that PCP significantly improved the physiological state of mouse intestine. Moreover, PCP strengthened the intestinal physical barrier by upregulating the expression of intestinal Occludin and ZO-1 and downregulating the levels of serum endotoxin, DAO, D-lactate, and intestinal MPO. Regarding biochemical barrier, PCP could upregulate the expression of MUC2, β-defensin, and SIgA in intestinal tissues. In addition, PCP modulated the immune barrier by increasing IL-2, IL-4, IL-6, IL-10, TGF-β, and IFN-γ expression. Besides, PCP increased the level of SCFAs in small intestinal contents. PCP modulates intestinal barrier function by altering the microbial composition of the gut. We also found that PCP could maintain intestinal barrier function by increasing the expression of Wnt/β-Catenin and Lrp5 proteins. Generally, our findings suggested that PCP may be used as a functional food to regulate intestinal mucosal function, thereby enhancing the health of the intestinal and host.

Abstract
The antidiabetic activity and underlying mechanisms of Fucus vesiculosus polysaccharide (FVP) were studied in type 2 diabetic rats. Our results exhibited that FVP intervention reversed body weight loss, alleviated hyperglycemia and insulin resistance in diabetic rats. FVP also had the potential to ameliorate dyslipidemia, liver and kidney dysfunction, decrease oxidative stress, promote glycogen synthesis, and boost short-chain fatty acid production and total bile acid excretion. 16S rRNA gene sequencing analysis suggested that FVP interfered with the gut microbiota in a beneficial manner. Moreover, RT-qPCR results demonstrated that the antidiabetic activity of FVP in connection with the acceleration of blood glucose absorption and glycogen synthesis, the inhibition of gluconeogenesis, and the regulation of lipid metabolism in the liver. These findings suggested that FVP had antidiabetic effects on high-fat diet and STZ-induced diabetic rats and could be a potential resource for treating type 2 diabetes mellitus.

Abstract
To evaluate the reproductive toxicity of gene modified rice generated by introducing phytoene synthase (Psy) and bacterial phytoene desaturase (CrtI) from maize and Erwinia uredovora, Wistar rats were allocated into 3 groups and fed with Psy and CrtI gene modified rice mixture diet (GM group), non-gene modified rice mixture diet (non-GM group), and AIN-93 diet (Blank control group) from parental generation (F0) to the offsprings (F1). GM rice, Heijinmi (HJM) and Non-GM rice, Heishuai (HS), were both formulated into diets at ratios of 73.5% and 75.5% according to the AIN93 diet for rodent animals, respectively. Relative to the non-GM group, no biologically relevant differences were observed in GM group rats concerning reproductive performance such as fertility rate, gestation rate, mean duration, hormone level, and reproductive organ pathology. The developmental parameters results were not significantly different from the non-GM group such as body weight, food consumption, developmental neurotoxicity, behavior, hematology, and serum chemistry. In terms of immunotoxicity, the IgG indicators of offspring from the GM group improved in contrast with the non-GM group. Additional gut flora analysis of F0 generation rats resulted as that the treatment elicited an increased gut microflora diversity of F0 rats. And no horizontal gene transfer of Psy and CrtI genes in rats fed a GM rice HJM diet. In conclusion, we found no adverse effects related to GM rice in the extended one-generation reproductive toxicity study, indicating that GM rice is a safe alternative for its counterpart rice regarding reproductive toxicity.

Abstract
Inflammatory bowel disease is a heterogeneous intestinal inflammatory disorder, including ulcerative colitis (UC) and Crohn's disease (CD). Existing studies have shown that the pathogenesis of IBD is closely related to the host's genetic susceptibility, intestinal flora disturbance and mucosal immune abnormalities, etc. It is generally believed that there are complicated interactions between host immunity and intestinal microflora/microRNAs during the occurrence and progression of IBD. Intestinal flora is mainly composed of bacteria, fungi, viruses and helminths. These commensals are highly implicated in the maintenance of intestinal microenvironment homeostasis alone or in combination. MiRNA is an endogenous non-coding small RNA with a length of 20 to 22 nucleotides, which can perform a variety of biological functions by silencing or activating target genes through complementary pairing bonds. A large quantity of miRNAs are involved in intestinal inflammation, mucosal barrier integrity, autophagy, vesicle transportation and other small RNA alterations in IBD circumstance. In this review, the immunomodulatory roles of gut flora and microRNAs are updated in the occurrence and progression of IBD. Meanwhile, the gut flora and microRNA targeted therapeutic strategies as well as other immunomodulatory approaches including TNF-α monoclonal antibodies are also emphasized in the treatment of IBD.

Abstract
The gut microbiome plays an important role in the variation of pharmacologic response. This aspect is especially important in the era of precision medicine, where understanding how and to what extent the gut microbiome interacts with drugs and their actions will be key to individualizing therapy. The impact of the composition of the gut microbiome on the efficacy of newer cancer therapies such as immune checkpoint inhibitors and chimeric antigen receptor T-cell treatment has become an active area of research. Pancreatic adenocarcinoma (PAC) has a poor prognosis even in those with potentially resectable disease, and treatment options are very limited. Newer studies have concluded that there is a synergistic effect for immunotherapy in combination with cytotoxic drugs, in the treatment of PAC. A variety of commensal microbiota can affect the efficacy of conventional chemotherapy and immunotherapy by modulating the tumor microenvironment in the treatment of PAC. This review will provide newer insights on the impact that alterations made in the gut microbial system have in the development and treatment of PAC.

Abstract
BACKGROUND Alcoholism is regarded as a risk factor for vitamin B12 (VB12) deficiency. Because VB12 serves as a coenzyme of methylmalonyl-CoA mutase, a key enzyme in propionate metabolism, the 13C-propionate breath test (PBT) has been studied as a non-invasive diagnostic modality for VB12 deficiency. However, the conventional PBT requires 2 h, which is inconvenient in clinical practice. We hypothesized that a faster PBT can be used to evaluate propionate metabolism and is more easily adaptable for clinical practice.
AIM To evaluate a faster PBT for assessing the effects of long-term ethanol consumption on propionate metabolism in ethanol-fed rats (ERs).
METHODS ERs were obtained by replacing standard drinking water (for control rats, CRs) with 16% ethanol solution in descendants of F344/DuCrj rats. Faster PBT was performed by administering 13C-propionate aqueous solution to male and female ERs and CRs by inserting a metal tubule from the mouth to the stomach; exhaled gas was collected in a bag to measure its 13CO2/12CO2 isotope ratio via infrared isotope spectrometry. Serum VB12 and alanine transaminase (ALT) levels were measured via chemiluminescence immunoassay and the lactate dehydrogenase-ultraviolet method, respectively. We evaluated statistical differences in mean body weight, change in 13CO2 (Δ13CO2‰), peak Δ13CO2‰, and serum VB12 and ALT, between males and females and between ERs and CRs using the t-test and Mann-Whitney U test for normally and non-normally distributed variables, respectively.
RESULTS Males weighed significantly more than females (P < 0.001); CRs weighed significantly more than ERs (P < 0.008). Δ13CO2 reached a peak (Cmax) at 20 min and 30 min in females and males, respectively, decreasing after 20-30 min without rebound in all groups. Males had significantly higher Cmax and Δ13CO2 at 15-45 min than females (P < 0.05; for all pairs). Propionate metabolism was enhanced in male ERs relative to male CRs, whereas metabolism did not differ markedly between ERs and CRs for females. Males had higher serum VB12 levels than females, without prominent differences between the ER and CR groups. Male CRs had notably higher ALT levels than male ERs. Thus, chronic ethanol consumption may trigger fatty acid production via intestinal bacteria and changes in gut microbiome composition.
CONCLUSION Faster PBT shows that 16% ethanol consumption promotes propionate metabolism without inducing liver injury. This PBT may be used clinically to evaluate gut flora status.

Abstract
The larvae of the black soldier fly, Hermetia illucens, are now attracting attention and becoming promising sources for aquafeed ingredient due to the nutritious substance. However, the introduction of a novel ingredient into the recipe may have unpredictable effects on the innate immune function and gut bacteria composition of crustaceans. Therefore, the present study aimed to evaluate how dietary black soldier fly larvae meal (BSFLM) affected the antioxidant ability, innate immunity and gut microbiome of shrimp (Litopenaeus vannamei) fed with a practical diet, including the gene expression of Toll and immunodeficiency (IMD) pathways. Six experimental diets were formulated by replacing gradient levels of fish meal (0 %, 10 %, 20 %, 30 %, 40 % and 50 %) based on a commercial shrimp diet. Four replicates of shrimp were fed different diets three times daily for 60 days. Growth performance linearly decreased with increasing BSFLM inclusion. Results of antioxidative enzyme activities and gene expression suggested that low dietary BSFLM levels activated the antioxidant capacity of shrimp, while dietary BSFLM levels up to 100 g/kg may induce oxidative stress and inhibit glutathione peroxidase activity. Although traf6, toll1, dorsal and relish were significantly upregulated in different BSFLM groups, the expression of tak1 was significantly downregulated in groups containing BSFLM, implying the immune susceptibility may be weakened. Gut flora analysis indicated dietary BSFLM altered both beneficial and opportunistic pathogenic bacterial abundance, with low levels of dietary BSFLM increased the abundance of bacteria that may contribute to carbohydrate utilization, while high levels of dietary BSFLM may cause intestinal disease and low intestinal immune response. To conclude, 60-80 g/kg of dietary BSFLM showed no adverse effects on the growth, antioxidant capacity and gut flora of shrimp, which was the adequate level in shrimp diet. While 100 g/kg dietary BSFLM may induce oxidative stress and potentially weaken the innate immunity of shrimp.

Abstract
INTRODUCTION In the industrialized world, the incidence of Allergic rhinitis (AR), often known as hay fever, and other allergic disorders continues to grow. Recent studies have suggested environmental variables such as bacterial exposures as a potential reason for the rising prevalence of AR. With breakthroughs in our abilities to research the complex crosstalk of bacteria, the gut microbiomes' effect on human development, nutritional requirements, and immunologic disorders has become apparent METHODS: Three search engines, including Scopus, Medline, and PubMed, were searched for related published articles up to and including 1st July 2022. RESULTS Several studies have investigated links between commensal microbiome alterations and the development of atopic diseases such as asthma and AR. Besides, studies using probiotics for treating AR suggest that they may alleviate symptoms and improve patient's quality of life. CONCLUSION Research on probiotics and synbiotics for AR suggests they may improve symptoms, quality of life, and laboratory indicators. A better treatment strategy with advantages for patients may be achieved using probiotics, but only if more detailed in vitro and in vivo investigations are conducted with more participants.

Recent studies have shown that intestinal flora exerts positive therapeutic effects on metabolic diseases, and plant-derived secondary metabolites are safe, effective and easy to prepare and also have an impact on intestinal flora and diabetes; these drugs have rarely been reviewed before as a class of drugs for diabetes, especially focusing on the intestinal flora. Therefore, studying the relationship between plant-derived secondary metabolites and diabetes mellitus is crucial. OBJECTIVE The objective of this study is to summarize and investigate the therapeutic mechanism of drugs extracted from natural plants effects on type 2 diabetes mellitus. METHODS The relationship between flora and type 2 diabetes was investigated by reviewing the recent experimental literature, and the pathways available for natural plant-derived secondary metabolites in the treatment of type 2 diabetes were summarized. RESULTS The therapeutic mechanisms of common plant-derived secondary metabolites for type 2 diabetes were summarized with a focus on the prebiotic efficacy of natural plant-derived secondary metabolites and the modulation of intestinal flora, and the mechanisms through which plant-derived secondary metabolites treat type 2 diabetes via effects on intestinal flora are further reviewed. CONCLUSION Common plant-derived secondary metabolites can play a role in regulating bacteria in the intestinal tract by enriching beneficial bacteria and removing harmful bacteria to achieve their therapeutic effect on type 2 diabetes. In addition, due to their excellent ability to regulate intestinal flora, plant-derived secondary metabolites may also have excellent efficacy in cancer and obesity, among other diseases. CLINICAL TRIAL REGISTRATION none.

Abstract
Green ecological prevention and control technology is a hot spot for aquatic disease research in recent years, and lactic acid bacteria is an important type of probiotic widely used in aquaculture. In this study, a strain of Lactobacillus plantarum Ep-M17 was isolated from the intestine of healthy grouper, which showed good antibacterial activity in vitro. To investigate the application prospects of Ep-M17 as a probiotic, we added it to the diet and fed Litopenaeus vannamei, and then detected its influence on the growth performance, survival rate, disease resistance, intestinal tissue structure, gene transcription, and the flora in the gut of shrimp. The results showed that feeding Ep-M17 increased the specific growth rate, reduced the feed conversion rate, improved the survival rate, and achieved a 76.9% relative protection rate after Vibrio parahaemolyticus E1 infection in shrimp. Histological examination displayed that Ep-M17-fed shrimp had a thick intestinal villi layer, which enhanced the protection against pathogen damage. It was also found that Ep-M17 significantly increased the activity levels of immune and digestion-related enzymes SOD, CAT, TRY, AKP, LIP, and AMS in the gut of shrimp, especially after V. parahaemolyticus E1 infection, these enzymes increased significantly higher than that of control. Transcriptome analysis revealed that Ep-M17 activated significantly differential expression of genes in immune, nutritional, metabolic, and Signal Transduction-related pathways in the gut of shrimp. In addition, Ep-M17 enriched the bacterial diversity of the shrimp gut, with a significant increase in many low-abundance bacterial species, a significant decrease in the number of pathogenic bacteria like Vibrio, and a significant increase in the number of beneficial bacteria. The above results evaluated that Ep-M17 as a potential probiotic can promote the growth and improve the disease resistance of shrimp by regulating the nutritional immune response and flora of the intestine.

Abstract
BACKGROUND Biliary atresia (BA) is one of the main causes of neonatal end-stage liver disease. Without timely diagnosis and treatment, most children with BA will develop irreversible liver fibrosis within the first two months. While current theorized causes of BA include viral infection, immune disorders, and genetic defects, the comprehensive etiology is still largely unknown. Recently, biliatresone attracted much interest for its ability to induce BA in both zebrafish and mice, so we summarized the latest progress of biliatresone research in BA and tried to answer the question of whether it could provide further clues to the etiology of human BA. DATA SOURCES We conducted a PubMed search for any published articles related to the topic using search terms including "biliary atresia", "biliatresone", "GSH", and "HSP90". Relevant data were extracted from the original text or supplementary materials of the corresponding articles. RESULTS Biliatresone had shown its unique toxicity in multiple species such as zebrafish and mice, and pathogenic factors involved included glutathione (GSH), heat shock protein 90 (HSP90) and the related pathways. In combination with epidemiological evidence and recent studies on the intestinal flora in biliary atresia, a new pathogenic hypothesis that the occurrence of biliary atresia is partly due to biliatresone or its structure-like compounds depositing in human body via vegetables or/and the altered intestinal flora structure can be tentatively established. CONCLUSIONS Based on the existing evidence, we emphasized that GSH and HSP90 are involved in the development of BA, and the maternal diet, especially higher vegetable intake of Asian women of childbearing age, accompanied by the altered intestinal flora structure, may contribute to the occurrence of biliary atresia and the higher incidence in the Asia group. However, the evidence from large sample epidemiological research is necessary.

Abstract
BACKGROUND AND AIMS This systematic review of animal studies aimed to identify anti-obesity medicinal herbs with prebiotic properties, and investigate their effects on gut microbiota and metabolic disorders. METHODS To obtain the relevant publications, four electronic databases were systematically searched up to June 2019. RESULTS Out of 1949 publications, 20 articles met the inclusion criteria in this study. Apart from body weight, some cases (n = 11) had reported the effects of medicinal herbs on metabolic parameters, including lipid profile (n = 7) and glycemic status (n = 4). CONCLUSION Although some medicinal herbs could be effective in modulating metabolic status and body weight, through making changes in the gut flora, further studies are needed to confirm the efficacy of such herbs in clinical trials.

Abstract
BACKGROUND Radiotherapy and chemotherapy can kill tumor cells and improve the survival rate of cancer patients. However, they can also damage normal cells and cause serious intestinal toxicity, leading to gastrointestinal mucositis[1]. Traditional Chinese medicine is effective in improving the side effects of chemotherapy. Wumei pills (WMP) was originally documented in the Treatise on Exogenous Febrile Diseases. It has a significant effect on chronic diarrhea and other gastrointestinal diseases, but it is not clear whether it affects chemotherapy-induced intestinal mucositis (CIM).
AIM To explore the potential mechanism of WMP in the treatment of CIM through experimental research.
METHODS We used an intraperitoneal injection of 5-fluorouracil (5-Fu) to establish a CIM mouse model and an oral gavage of WMP decoction (11325 and 22650 mg/kg) to evaluate the efficacy of WMP in CIM. We evaluated the effect of WMP on CIM by observing the general conditions of the mice (body weight, food intake, spleen weight, diarrhea score, and hematoxylin and eosin stained tissues). The expression of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), IL-1β, and myeloperoxidase (MPO), as well as the Toll-like receptor 4/myeloid differentiation factor 88/nuclear factor-κB (TLR4/MyD88/NF-κB) signaling pathway proteins and tight junction proteins (zonula occludens-1, claudin-1, E-cadherin, and mucin-2) was determined. Furthermore, intestinal permeability, intestinal flora, and the levels of short-chain fatty acids (SCFA) were also assessed.
RESULTS WMP effectively improved the body weight, spleen weight, food intake, diarrhea score, and inflammatory status of the mice with intestinal mucositis, which preliminarily confirmed the efficacy of WMP in CIM. Further experiments showed that in addition to reducing the levels of TNF-α, IL-1β, IL-6, and MPO and inhibiting the expression of the TLR4/MyD88/NF-κB pathway proteins, WMP also repaired the integrity of the mucosal barrier of mice, regulated the intestinal flora, and increased the levels of SCFA (such as butyric acid).
CONCLUSION WMP can play a therapeutic role in CIM by alleviating inflammation, restoring the mucosal barrier, and regulating gut microbiota.

Abstract
Oral administration of peptides/proteins with superior efficacy and fewer side effects is the most advantageous route of administration. In this study, we utilized controllable enzymatic (animal protease) hydrolysis technology to prepare active polypeptide self-assembling supramolecular (APs) from marine shellfish meat to explore the functional mechanism of APs in in vitro and in vivo (oral administration) experiments . In vitro experiments revealed that APs with self-assembly tendency had multifunctional activities. In vivo experiments indicated that oral administration of naturally safe APs could inhibited inflammation, promoted fibroblast proliferation and revascularization, and accelerated the epithelialization process, thus favoring a balanced repair tissue collagen I/III ratio and the promotion of hair follicle regeneration to achieve scarless healing, which was also relevant to "skin-gut" axis. These results showed that APs, as demonstrated in this study, promoted dermal wound healing in mice and may be developed and used to treat skin wounds.

Abstract
There is an expanding body of research on the bidirectional relationship of the human gut microbiome and cardiovascular disease, including heart failure (HF). Researchers are examining the microbiome and gut metabolites, primarily trimethylamine-N-oxide (TMAO), to understand clinically observed outcomes. This systematic review explored the current state of the science on the evaluation and testing of the gut biome in persons with HF. Using electronic search methods of Medline, Embase, CINAHL, and Web of Science, until December 2021, we identified 511 HF biome investigations between 2014 and 2021. Of the 30 studies included in the review, six were 16S rRNA and nineteen TMAO, and three both TMAO and 16S rRNA, and two bacterial cultures. A limited range of study designs were represented, the majority involving single cohorts (n = 10) and comparing individuals with HF to controls (n = 15). Patients with HF had less biodiversity in fecal samples compared to controls. TMAO is associated with age, BNP, eGFR, HF severity, and poor outcomes including hospitalizations and mortality. Inconsistent across studies was the ability of TMAO to predict HF development, the independent prognostic value of TMAO when controlling for renal indices, and the relationship of TMAO to LVEF and CRP. Gut microbiome dysbiosis is associated with HF diagnosis, disease severity, and prognostication related to hospitalizations and mortality. Gut microbiome research in patients with HF is developing. Further longitudinal and multi-centered studies are required to inform interventions to promote clinical decision-making and improved patient outcomes.

Abstract
Gut dysbiosis induces 'leaky gut,' a condition associated with diabetes, NASH, and various auto-immune diseases. Porphyromonas gingivalis is a periodontopathic bacterium which causes periodontal tissue breakdown, and often enters the systemic blood flow. Oral administration of P. gingivalis induced gut dysbiosis in mice model, but no systemic administration of P. gingivalis has been reported thus far. In the present study, we investigated the effect of P. gingivalis-derived lipopolysaccharide (Pg-LPS) on the intestinal flora of our established mouse model. Eight-week-old C57BL/6J mice were intraperitoneally administered Pg-LPS. Three months later, DNA was extracted from stool, and RNA from the small and large intestines. After euthanizing the mice, pathological sections of the intestinal tract were prepared and stained with hematoxylin and eosin (H&E). Tumor necrosis factor alpha (TNF-α), interleukin (IL)-1β, and IL-6 expression levels were evaluated using quantitative PCR. 16S rRNA gene PCR amplicon analysis data were acquired using NGS. Microbial diversity and composition were analyzed using Quantitative Insights into Microbial Ecology 2. Furthermore, alterations in microbial function were performed by PICRUSt2. No significant inflammatory changes were observed in the H&E. No significant differences in the mRNA levels of IL-1β, IL-6, and TNF-α were observed between the groups. Pg-LPS administration decreased the abundance of Allobacterium in the gut. A predictive metagenomic analysis by PICRUSt2 and STAMP showed that 47 pathways increased and 17 pathways decreased after Pg-LPS administration. Systemic application of periodontal pathogens may cause changes in the intestinal flora which may affect the physiological functions of the intestinal tract.

Abstract
Kidney-Yang deficiency syndrome, a common traditional Chinese medicine syndrome of diarrhea, has a complex pathogenesis. This paper explores the mechanisms of the development of diarrhea with kidney-Yang deficiency syndrome from three aspects: Gut flora, signaling pathway, and molecules related to the "kidney-gut axis", and tries to identify biomarkers for diarrhea with kidney-Yang deficiency syndrome. It is of great significance to reveal the modern biological connotation of diarrhea with kidney-Yang deficiency syndrome, which can promote the subsequent clinical targeted therapy.

Abstract
Deoxynivalenol (DON), a trichothecene mycotoxin, is one of the most globally prevalent mycotoxins mainly produced by Fusarium species. DON exposure can cause spectrum of symptoms such as nausea, vomiting, gastroenteritis, growth retardation, immunosuppression, and intestinal flora disorders in humans and animals. Therefore, the implication of DON degradation technology is of great significance for food safety. Recently, photocatalytic degradation technology has been applied for DON control. However, the toxicity of the intermediates identified in the degradation process was often ignored. In this work, based on previous successful degradation of DON and evaluation of the in vitro toxicity of DON photocatalytic detoxification products (DPDPs), we further studied the in vivo toxicity of DPDPs and mainly explored their effects on intestinal barrier function and intestinal flora in mice. The results demonstrated that the DPDPs treated with photocatalyst for 120 min effectively increased the expression of intestinal tight junction proteins and improved the disorder of gut flora. Meanwhile, compared with DON-exposed mice, the DPDPs reduced the level of inflammation and oxidative stress of intestinal tissue, and improved growth performance, enterohepatic circulation, energy metabolism, and autonomic activity. All the results indicated that the toxicity of the DPDPs irradiated for 120 min was much lower than that of DON or even nontoxic. Therefore, we hope that this photocatalytic degradation technology can be used as a promising tool for the detoxification of mycotoxins.

Abstract
BACKGROUND Women with postpartum psychiatric disorders are prone to severe anorexia. Clinical studies have revealed the efficacy of 919 syrup, a traditional Chinese medicine mixture against postpartum illnesses, such as in regulating maternal mood and improving postpartum anorexia. AIM This study investigated the mechanisms through which 919 syrup improved anorexia induced by postpartum stress, focussing on the combined peroxisome proliferator-activated receptor gamma (PPARγ) and leptin signalling pathway, and its effects on the structure of the gut flora. METHODS Mice were randomly divided into five groups-control group, immobilisation stressed (IS) group (normal saline), pioglitazone (Piog; western medicine control) group, 919 syrup low-dose (TJD; 13.5 g/kg) group, and 919 syrup high-dose (TJG; 27.0 g/kg) group. The control group was housed normally. The other groups received IS for 3 h daily for 21 days. The treatments were initiated following the first postnatal day and were administered by gastric gavage. All mice were sacrificed under anaesthesia on postnatal day 22. Blood, hypothalamus, stomach, and faecal specimens were collected. Gene and protein expression levels of components of the PPARγ-leptin signalling pathway in the serum, hypothalamus, and stomach were determined. Immunofluorescence staining for proopiomelanocortin (POMC), phosphorylated signal transducer and activator of transcription 3 (pSTAT3), and leptin was performed to observe their spatial distributions in the hypothalamus and stomach. 16s rRNA gene sequencing and bioinformatics analysis of fecal specimens were performed. RESULTS After IS, postpartum mice showed significantly reduced appetite and body weight, accompanied by abnormalities in the structure of the gut flora. Treatment with 919 syrup (27.0 g/kg) downregulated malondialdehyde and upregulated catalase, glutathione peroxidase, and superoxide dismutase by activating PPARγ, thereby affecting the expression of leptin signalling pathway components (leptin, leptin receptor, pSTAT3, POMC, and cocaine and amphetamine-related transcript and neuropeptide Y), and modulated the gut flora in stressed mice. CONCLUSION 919 syrup improved appetite in mice with postnatal stress by activating PPARγ to induce crosstalk with the leptin signalling pathway, this mechanism was similar to that of PPARγ agonists. 919 syrup also improved gut flora structure, and the changes in the relative abundances of the gut flora strongly correlated with the expression levels of PPARγ and leptin pathway components.

Abstract
BACKGROUND Keshan disease is an endemic cardiomyopathy of undefined causes. Being involved in the unclear pathogenesis of Keshan disease, a clear diagnosis, and effective treatment cannot be initiated. However, the rapid development of gut flora in cardiovascular disease combined with omics and big data platforms may promote the discovery of new diagnostic markers and provide new therapeutic options. This study aims to identify biomarkers for the early diagnosis and further explore new therapeutic targets for Keshan disease. METHODS This cohort study consists of two parts. Though the first part includes 300 participants, however, recruiting will be continued for the eligible participants. After rigorous screening, the blood samples, stools, electrocardiograms, and ultrasonic cardiogram data would be collected from participants to elucidate the relationship between gut flora and host. The second part includes a prospective follow-up study for every 6 months within 2 years. Finally, deep mining of big data and rapid machine learning will be employed to analyze the baseline data, experimental data, and clinical data to seek out the new biomarkers to predict the pathogenesis of Keshan disease. DISCUSSION Our study will clarify the distribution of gut flora in patients with Keshan disease and the abundance and population changes of gut flora in different stages of the disease. Through the big data platform analyze the relationship between environmental factors, clinical factors, and gut flora, the main factors affecting the occurrence of Keshan disease were identified, and the changed molecular pathways of gut flora were predicted. Finally, the specific gut flora and molecular pathways affecting Keshan disease were identified by metagenomics combined with metabonomic analysis. TRIAL REGISTRATION ChiCTR1900026639.

Abstract
In the past decades, the fields of microbiology and immunology have largely advanced by using germ-free animals and next-generation sequencing. Many studies revealed the relationship among gut microbiota, activation of immune system, and various diseases. Especially, some gut commensals can generate their antigen-specific T cells. It is becoming clear that commensal bacteria have important roles in various autoimmune and inflammatory diseases, such as autism, rheumatoid arthritis (RA), and inflammatory bowel diseases (IBD). Recently, it was reported that commensals contribute to the cancer immune therapy. However, how commensal-specific T cells contribute to the disease development and cancer treatment are not fully understood yet. In this chapter, we will summarize the decade history of the studies associated with commensal-induced T cells and commensal-causing diseases.

Abstract
Female stag beetles (Lucanidae) possess internal mycangia to maintain microbial cultures. Yeasts from these mycangia may help with larval nutrition in nutrient poor woody substrates, but only a few Lucanidae taxa have been studied and all reports originate from Europe and Asia. We identify the first mycangial yeasts of a South African endemic Lucanidae beetle, Xiphodontus antilope, using nuclear ribosomal RNA and ITS DNA sequence data. In addition we identified yeasts from the larval gut, fecal matter, frass and woody substrate surrounding larvae and pupae. The mycangium of X. antilope was confined to females and is structurally similar to all other Lucanidae. Unlike most Lucanidae that seemingly associate with single species of yeast, or whose mycangia contain yeast monocultures, three yeast species were commonly isolated from X. antilope. Scheffersomyces coipomoensis was the most numerically dominant species on most substrates and in most individuals, but a second, undescribed, Scheffersomyces species was present in high numbers. A third species, also undescribed and unrelated to Scheffersomyces, was recovered from all mycangia but could not be detected in the larval gut, fecal matter, frass or woody substrates. We confirm a close association of Scheffersomyces yeasts with Lucanidae globally, but other taxa may also be involved. We show that the predominant mycangial yeasts also form the predominant yeasts within the larval gut and the woody substrates around the larvae and pupae. This combined external and internal colonization by the same yeasts may provide enhanced opportunities for nutrient acquisition, but this needs validation in future studies.

Abstract
Colorectal cancer (CRC) is one of the major malignancies in humans. This study was designed to evaluate the effects of fucoidan on gut flora and tumor prevention in 1,2-dimethylhydrazine-induced colorectal carcinogenesis in rats. We found that dietary fucoidan treatment decreased the tumor incidence and mean tumor weight and increased cell apoptosis. Fucoidan treatment decreased the expression of β-catenin C-Myc, CyclinD1 and Survivin, while the Hippo pathway was activated with increased phosphorylation levels of mammalian sterile 20-like kinase 1 and 2, large tumor suppressor 1 and 2, and Yes-associated protein. Compared with the model group, the levels of interleukin (IL)-17 and IL-23 were decreased, but the levels of interferon-γ, IL-4 and IL-10 were increased, in the fucoidan group. Fucoidan treatment increased natural killer cells in peripheral blood and the proportion of CD4+ T cells. Immunofluorescence detection of colorectal tumor tissues showed decreased expression of Foxp3 and up-regulated expression of CD68 in the fucoidan group. Moreover, fucoidan treatment decreased the levels of diamine oxidase and lipopolysaccharides and up-regulated the levels of tight junction proteins. 16S rDNA high-throughput sequencing revealed that fucoidan treatment decreased the abundance of Prevotella and increased the abundance of Alloprevotella. Fucoidan increased the levels of butyric acid and valeric acid compared to the model group. This study provides experimental evidence that dietary fucoidan may prevent colorectal tumorigenesis by regulating gut microecology and body immunity. Meanwhile, fucoidan activated the Hippo pathway and down-regulated the β-catenin pathway to induce tumor cell apoptosis and suppress tumor growth.

Abstract
Purpose To assess the association between changes in gut flora and serum inflammatory factors in children with noninfectious diarrhea. Basic Procedure Ninety-three children diagnosed with and treated for noninfectious diarrhea (diarrhea group) and 80 healthy children (healthy control group) were enrolled in this study. Fresh fecal samples were diluted, and after cultivating bacteria for 48 hours at 37°C, we compared the number of bacterial cells in gut flora per gram of feces and determined gut colonization resistance. Findings The abundance of Escherichia coli and Enterococcus in feces was significantly higher in the diarrhea group than in the healthy control group. Conversely, the abundance of Bifidobacterium and lactic acid bacteria was significantly lower in the diarrhea group than in the healthy control group. Serum interleukin (IL)-1, IL-6, IL-17, and tumor necrosis factor (TNF)-α levels in the diarrhea group were significantly higher than those in the healthy control group. Pearson’s correlation analysis revealed that serum IL-1, IL-6, IL-17, and TNF-α levels positively correlated with abundance of E. coli and Enterococcus and negatively correlated with abundance of Bifidobacterium and lactic acid bacteria. Conclusions Gut dysbacteriosis and overexpression of serum inflammatory factors occur in children with noninfectious diarrhea and are closely correlated.

Abstract
INTRODUCTION Selenium plays important roles in antagonizing the toxicity of methylmercury. The underlying mechanism for the antagonism between Se and MeHg is still not fully understood. OBJECTIVE The role of gut flora against the toxicity of environmental contaminants is receiving more and more attention. The objective of this study was to investigate the role of Se against MeHg-poisoning in the modulation of gut flora and the decomposition of MeHg. METHODS MeHg-poisoned rats were treated with sodium selenite every other day for 90 days. Fecal samples were collected on Day 8, 30, 60 and 90. Gut flora in feces was determined using 16S rRNA gene profiling, and the concentrations of Se and total mercury (THg) were measured by ICP-MS, and the concentration of MeHg was measured by CVAFS. RESULTS Gut flora at both the ranks of phylum and genus in the MeHg-poisoned rats after Se treatment was modulated towards that in the control group, suggesting the restoration of the profile of gut flora. Increased THg was found in fecal samples after Se treatment on day 30. The percentage of MeHg (of total mercury) in the MeHg-poisoned group was in the range of 81-105% while it was 65-84% in the Se treatment group on different days, suggesting the increased decomposition of MeHg in MeHg-poisoned rats after Se treatment. CONCLUSIONS This study suggests that MeHg poisoning damaged the abundance of gut flora and decreased their capacity for the decomposition of MeHg. After Se treatment, the abundance of gut flora was partially restored and the decomposition and excretion of MeHg was enhanced. These findings suggest that the modulation of gut flora may be one way to promote the health status in MeHg-poisoned rats and possibly in human beings.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Hawthorn is a traditional Chinese medicine for high-calorie-diet-induced dyspepsia (HC-DID) for thousands of years old. Based on traditional Chinese medicine (TCM) theory and clinical and non-clinical trials, its stir-frying processed product, charred hawthorn, possesses better effect. At present, most research mainly focuses on chemical constituents of hawthorn before and after stir-frying process, but there is no relevant action-mechanism study about fragrant odor promoting HC-DID during the stir-frying process of the hawthorn. AIM OF THE STUDY The purpose of the present study is to research on mechanism of hawthorn decoction coupled with odor of charred hawthorn on digestive in rats with HC-DID. MATERIALS AND METHODS The SPF Kunming (KM) mice and Sprague Dawley (SD) rats were randomly divided into 7 groups: control group, model group, cisapride group, hawthorn group (HT), charred hawthorn group (CHT), odor of charred hawthorn (OCHT), CHT + OCHT group. The rats were modeled as HC-DID, whose treatment by intragastric administration and odor administration. Obvious symptoms of HC-DID were observed. Gastrointestinal motility were detected. Histopathology was performed in hypothalamus and gastrointestinal tract. Related brain-gut peptides were assayed in serum, hypothalamus and gastrointestinal tract. Illumina Miseq platform was used for 16S rDNA high-throughput sequencing to detect the intestinal flora structure of the caecum of rats. RESULTS Traditional Chinese medicine decoction of hawthorn (HT and CHT) regulated the body weight, food intake, gastrointestinal motility and abnormal secretion of brain-gut peptides in rats with HC-DID, and the odor of charred hawthorn also had good curative effect for it. Moreover, the intestinal dysbiosis was induced by high-calorie diet in rats with dyspepsia, and hawthorn decoction could ease this trend. CONCLUSION The above study showed that hawthorn decoction coupled with the odor of charred hawthorn effectively alleviate HC-DID in rats by regulating the "Brain-Gut" axis and gut flora. Odor treatment of hawthorn could be a potential therapeutic approach for HC-DID.

Abstract
Gut microbiota have been shown to affect various cellular and host response elements such as immunological, neurological, energy, storage, etc. In recent years, this has led to rapid expansion in dietary products containing probiotics, prebiotics and combination thereof in synbiotics. While benefits of consuming functional foods derived from probiotics strains have been demonstrated for various metabolites, a detailed analysis of the biochemical footprints and their benefits remain under-studied. Herein, using a combination of NMR metabolomics, microbial techniques and cell-culture assays, we have characterized metabolite profiles of probiotic viz. Lactobacillus delbruekii ATCC 9649, Lactobacillus casei ATCC 335, Lactobacillus plantarum NRC 716 and Bacillus coagulans ATCC 12425 cultures in fermented milk. We identified predominance of sugars, small chain fatty acids, organic acids and branched chain amino acids from natural abundance 13C NMR studies. Additionally, we identified myriad metabolites and their respective pathways using 1H NMR spectroscopy. Based on our findings, synbiotic fermented dairy products were customized with co-cultures and complemented with pro- and pre- biotics. Furthermore, we demonstrate epithelial cell interaction and anti-microbial activity of L. plantarum based ferment against a range of bacterial pathogens highlighting possible biochemical mechanisms for anti-microbial activity, quorum sensing, gut colonization and other beneficial factors that may be crucial. Furthermore, we propose plausible explanation against non-communicable diseases such as tumor-inhibitory, anti-proliferative and pro-apoptotic effects which has direct implications for dietary therapeutics.

Abstract
BACKGROUND Hypericum attenuatum Choisy, a traditional Chinese herb, has been shown to be effective in the treatment of diseases associated with inflammation and has been used to treat rheumatic arthritis in China for centuries. However, the underlying mechanism of its anti-inflammatory effect is poorly understood. HYPOTHESIS/PURPOSE In this study, we aimed to investigate the anti-inflammatory mechanisms of EtOAc fractions of H. attenuatum Choisy (Ha-EtOAc) on lipopolysaccharide (LPS)-induced RAW264.7 macrophage inflammation and hypothesized that Ha-EtOAc could attenuate inflammation in the colon. STUDY DESIGN LPS was utilized to induce RAW264.7 cells inflammation. The anti-inflammatory effect of Ha-EtOAc in RAW264.7 cells was evaluated by measuring the inhibition ratio of nitric oxide (NO) production. Murine ulcerative colitis (UC) was induced by treatment with 2.5% dextran sulfate sodium (DSS). The basic indexes of the mice, including body weight, food intake and hematochezia, were recorded during mice experiments. METHODS The expression levels of pro-inflammatory cytokines, including TNF-α, IL-6 and IL-1β, were measured by quantitative real-time PCR and western blot. Additionally, the influences of Ha-EtOAc on the NF-κB and MAPK signaling pathways were determined by western blot and immunofluorescence assays. In addition, the impact of Ha-EtOAc on gut microbiota of mice with UC was detected by 16S rDNA sequencing. RESULTS Ha-EtOAc inhibited the LPS-induced production of NO and decreased the release of TNF-α, IL-6 and IL-1β in RAW264.7 cells in a dose-dependent manner. In addition, pretreatment with Ha-EtOAc could suppress the nuclear translocation of p65 and the phosphorylation of Erk1/2, p38 and JNK. Ha-EtOAc treatment ameliorated murine UC, as reflected by a reduced body weight loss, improved colon shortening, alleviated mucosal damage and decreased releases of pro-inflammatory cytokines. Furthermore, Ha-EtOAc could modulate the composition of microbial communities. CONCLUSION Our results demonstrated that Ha-EtOAc exhibited anti-inflammatory effects mainly by suppressing the NF-κB and MAPK pathways, and Ha-EtOAc treatment may be a potent therapy for the treatment of ulcerative colitis.

Abstract
BACKGROUND Schizophrenia (SZ) is a complex psychiatric disorder and the exact mechanisms that underpin SZ remain poorly understood despite decades of research. Genetic, epigenetic, and environmental factors are all considered to play a role. The importance of gut flora and its influence on the central nervous system has been recognized in recent years. We hypothesize that gut flora may be a converging point where environmental factors interact with epigenetic factors and contribute to SZ pathogenesis. AIM To summarize the current understanding of genetic and epigenetic factors and the possible involvement of gut flora in the pathogenesis of schizophrenia. RESULTS We searched PubMed and Medline with a combination of the key words schizophrenia, microbiome, epigenetic factors to identify studies of genetic and epigenetic factors in the pathogenesis of schizophrenia. Numerous genes that encode key proteins in neuronal signaling pathways have been linked to SZ. Epigenetic modifications, particularly, methylation and acetylation profiles, have been found to differ in individuals that present with SZ from those that don't. Gut flora may affect epigenetic modifications by regulation of key metabolic pathway molecules, including methionine, florate, biotin, and metabolites that are acetyl group donors. Despite a lack of direct studies on the subject, it is possible that gut flora may influence genetic and epigenetic expression and thereby contribute to the pathogenesis of SZ. CONCLUSION Gut flora is sensitive to both internal and environmental stimuli and the synthesis of some key molecules that participate in the epigenetic modulation of gene expression. Therefore, it is possible that gut flora is a converging point where environmental factors interact with genetic and epigenetic factors in the pathogenesis of SZ.

Abstract
Metformin is the first-choice therapy to lower glycaemia and manage type 2 diabetes. Continuously emerging epidemiological data and experimental models are showing additional protective effects of metformin against a number of age-related diseases (ARDs), e.g., cardiovascular diseases and cancer. This evidence has prompted the design of a specific trial, i.e., the Targeting Aging with Metformin (TAME) trial, to test metformin as an anti-ageing molecule. However, a unifying or prevailing mechanism of action of metformin is still debated. Here, we summarize the epidemiological data linking metformin to ARD prevention. Then, we dissect the deeply studied mechanisms of action explaining its antihyperglycemic effect and the putative mechanisms supporting its anti-ageing properties, focusing on studies using clinically pertinent doses. We hypothesize that the molecular observations obtained in different models with metformin could be indirectly mediated by its effect on gut flora. Novel evidence suggests that metformin reshapes the human microbiota, promoting the growth of beneficial bacterial species and counteracting the expansion of detrimental bacterial species. In turn, this action would influence the balance between pro- and anti-inflammatory circulating factors, thereby promoting glycaemic control and healthy ageing. This framework may reconcile diverse observations, providing information for designing further studies to elucidate the complex interplay between metformin and the metabiome harboured in mammalian body compartments, thereby paving the way for innovative, bacterial-based therapeutics to manage type 2 diabetes and foster a longer healthspan.

Abstract
Colorectal cancer is one of the most frequently diagnosed cancers worldwide. Gut flora can modulate the host response to chemotherapeutic drugs. However, the understanding regarding the relationship between the gut microbiota and the antitumor efficacy of 5- Fluorouracil (5-FU) treatment is limited. Therefore, we compared the tumor size and profiled the gut microbiota of mice treated with 5-FU, combined with probiotics or ABX (an antibiotic cocktail of antibiotics) by using the Colorectal Cancer (CRC) mouse model and high-throughput sequencing. The results elucidated that ABX administration diminished the antitumor efficacy of 5-FU in mice and supplementation of probiotics upon 5-FU treatment could not significantly increase the efficacy of 5-FU treatment, despite improving mice body weight at day 33. There were significant differences in fecal bacteria community among the four groups (ANOSIM p < 0.05). ABX administration reduced microbiota biodiversity and altered microbiota community. The pathogenic bacteria included Escherichia shigella and Enterobacter significantly increased, while other commensal bacterial decreased unidentified Firmicutes increased and the opportunistic pathogens decreased after the administration of Probiotics. In addition, 5-FU treatment also changed the diversity and the community composition of the gut mirobiota. The relative abundance of genus Lachnospiracea_NK4 A136, Bacteroides, Odoribacter, Mucispirillum, and Blautia were significantly increased compared to the control group. Additionally, functional capacity analysis of gut microbiota using PICRUSt showed that genes involved in amino acid metabolism, replication and repair translation, nucleotide metabolism expressed much lower in FU.ABX group than the other groups. The current results suggest that ABX administration disrupted the gut microbiota in mice, which contributed to the reduction of antitumor efficacy of 5-FU.

Abstract
BACKGROUND Research suggests that heart failure with reduced ejection fraction (HFrEF) is a state of systemic inflammation that may be triggered by microbial products passing into the bloodstream through a compromised intestinal barrier. However, whether the intestinal microbiota exhibits dysbiosis in HFrEF patients is largely unknown.Methods and Results:Twenty eight non-ischemic HFrEF patients and 19 healthy controls were assessed by 16S rRNA analysis of bacterial DNA extracted from stool samples. After processing of sequencing data, bacteria were taxonomically classified, diversity indices were used to examine microbial ecology, and relative abundances of common core genera were compared between groups. Furthermore, we predicted gene carriage for bacterial metabolic pathways and inferred microbial interaction networks on multiple taxonomic levels.Bacterial communities of both groups were dominated by the Firmicutes and Bacteroidetes phyla. The most abundant genus in both groups wasBacteroides. Although α diversity did not differ between groups, ordination by β diversity metrics revealed a separation of the groups across components of variation.StreptococcusandVeillonellawere enriched in the common core microbiota of patients, whileSMB53was depleted. Gene families in amino acid, carbohydrate, vitamin, and xenobiotic metabolism showed significant differences between groups. Interaction networks revealed a higher degree of correlations between bacteria in patients. CONCLUSIONS Non-ischemic HFrEF patients exhibited multidimensional differences in intestinal microbial communities compared with healthy subjects.

Abstract
SCOPE α-Cyclodextrin (α-CD), a cyclic polymer of glucose, has been shown to lower plasma cholesterol in animals and humans; however, its effect on atherosclerosis has not been previously described. METHODS AND RESULTS apoE-knockout mice were fed either low-fat diet (LFD; 5.2% fat, w/w), or Western high fat diet (21.2% fat) containing either no additions (WD), 1.5% α-CD (WDA); 1.5% β-CD (WDB); or 1.5% oligofructose-enriched inulin (WDI). Although plasma lipids were similar after 11 weeks on the WD vs. WDA diets, aortic atherosclerotic lesions were 65% less in mice on WDA compared to WD (P < 0.05), and similar to mice fed the LFD. No effect on atherosclerosis was observed for the other WD supplemented diets. By RNA-seq analysis of 16S rRNA, addition of α-CD to the WD resulted in significantly decreased cecal bacterial counts in genera Clostridium and Turicibacterium, and significantly increased Dehalobacteriaceae. At family level, Comamonadaceae significantly increased and Peptostreptococcaceae showed a negative trend. Several of these bacterial count changes correlated negatively with % atherosclerotic lesion and were associated with increased cecum weight and decreased plasma cholesterol levels. CONCLUSION Addition of α-CD to the diet of apoE-knockout mice decreases atherosclerosis and is associated with changes in the gut flora.

Abstract
Current nutrition research is focusing on health promotion, disease prevention, and performance improvement for individuals and communities around the world. The humans with required nutritional ingredients depend on both how well the individual is provided with balanced foods and what state of gut microbiota the host has. Studying the mutually beneficial relationships between gut microbiome and host is an increasing attention in biomedical science. The purpose of this study is to understand the role of gut microbiota and to study interactions between gut microbiota and host. In this study, we used a shotgun proteomic approach to reveal the serum and liver proteomes in gut-microbiota-lacking mice. For serum, 15 and 8 proteins were uniquely detected in specific-pathogen-free (SPF) and germ-free (GF) mice, respectively, as well as the 3 and 20 proteins were significantly increased and decreased, respectively, in GF mice compared to SPF mice. Among the proteins of the serum, major urinary protein 1 (MUP-1) of GF mice was significantly decreased compared to SPF mice. In addition, MUP-1 expression is primarily regulated by testosterone. Lacking in gut flora has been implicated in many adverse effects, and now we have found its pathogenic root maybe gut bacteria can regulate the sex-hormone testosterone levels. In the liver, 8 and 22 proteins were uniquely detected in GF mice and SPF mice, respectively, as well as the 14 and 30 proteins were significantly increased and decreased, respectively, in GF mice compared to SPF mice. Furthermore, ingenuity pathway analysis (IPA) indicated that gut microbiota influence the host in cancer, organismal injury and abnormalities, respiratory disease; cell cycle, cellular movement and tissue development; cardiovascular disease, reproductive system disease; and lipid metabolism, molecular transport and small molecule biochemistry. Our findings provide more detailed information of the role of gut microbiota and will be useful to help study gut bacteria and disease prevention.

Abstract
The worldwide interest in the gut microbiome and its impact on the upstream liver highlight a critical upside to breath research: it can uniquely measure otherwise unmeasurable biology. Bacteria make gases [volatile organic compounds (VOCs)] that are directly relevant to pathophysiology of the fatty liver and associated conditions, including obesity. Measurement of these VOCs and their metabolites in the exhaled breath, therefore, present an opportunity to safely and easily evaluate, on both a personal and a population level, some of our most pressing public health threats. This is an opportunity that must be pursued. To date, however, breath analysis remains a slowly evolving field which only occasionally impacts clinical research or patient care. One major obstacle to progress is that breath analysis is inherently and emphatically mutli-disciplinary: it connects engineering, chemistry, breath mechanics, biology and medicine. Unbalanced or incomplete teams may produce inconsistent and often unsatisfactory results. A second impediment is the lack of a well-known stepwise structure for the development of non-invasive diagnostics. As a result, the breath research landscape is replete with orphaned single-center pilot studies. Often, important hypotheses and key observations have not been pursued to maturation. This paper reviews the rationale and requirements for breath VOC research applied to the gut-fatty liver axis and offers some suggestions for future development.

Abstract
The aromatic compound p-cresol (4-methylphenol) has been found elevated in the urines of Italian autistic children up to 8 years of age. The present study aims at replicating these initial findings in an ethnically distinct sample and at extending them by measuring also the three components of urinary p-cresol, namely p-cresylsulfate, p-cresylglucuronate and free p-cresol. Total urinary p-cresol, p-cresylsulfate and p-cresylglucuronate were significantly elevated in 33 French autism spectrum disorder (ASD) cases compared with 33 sex- and age-matched controls (p < 0.05). This increase was limited to ASD children aged ≤8 years (p < 0.01), and not older (p = 0.17). Urinary levels of p-cresol and p-cresylsulfate were associated with stereotypic, compulsive/repetitive behaviors (p < 0.05), although not with overall autism severity. These results confirm the elevation of urinary p-cresol in a sizable set of small autistic children and spur interest into biomarker roles for p-cresol and p-cresylsulfate in autism.

Abstract
BACKGROUND Small intestinal bacterial overgrowth (SIBO) is known to occur in patients with chronic pancreatitis, particularly of alcoholic etiology. There are, however, scanty data on frequency of SIBO in patients with chronic idiopathic pancreatitis and factors associated with its occurrence. METHODS 68 patients with chronic pancreatitis and 74 age and gender-matched healthy subjects (HS) were evaluated for SIBO using glucose hydrogen breath test (GHBT). Persistent rise in breath hydrogen 12 ppm above basal (at least two recordings) was diagnostic of SIBO. RESULT SIBO was diagnosed more often among patients with chronic pancreatitis than controls (10/68 [14.7%] vs. 1/74 controls [1.3%]; p = 0.003). Of 68 patients, 22 (32.3%) had alcoholic and 46 (67.6%) had idiopathic chronic pancreatitis. SIBO was as commonly detected among patients with alcoholic as idiopathic pancreatitis (3/22 [13.6%] vs. 7/46 [15.2%]; p = 0.86). Age, gender, body mass index (BMI), steatorrhoea, pain, analgesic use, pancreatic calcifications and use of pancreatic enzyme supplements had no relationship with the presence of SIBO. Diabetes mellitus tended to be commoner among patients with chronic pancreatitis with than without SIBO (6/10 [60%] vs. 18/58 [31%]; p = 0.07). CONCLUSION SIBO was commoner among patients with chronic pancreatitis, both alcoholic and idiopathic, than HS. Though presence of SIBO among patients with chronic pancreatitis tended to be commoner among those with diabetes mellitus, there was no relationship with age, gender, BMI, steatorrhoea, pain, analgesic use, pancreatic calcifications and use of pancreatic enzyme supplements.

Abstract
The current review focuses on pre- and post-natal development of intestinal immunoglobulin A (IgA) production in pig. IgA production is influenced by intrinsic genetic factors in the foetus as well as extrinsic environmental factors during the post-natal period. At birth, piglets are exposed to new antigens through maternal colostrums/milk as well as exogenous microbiota. This exposure to new antigens is critical for the proper development of the gut mucosal immune system and is characterized mainly by the establishment of IgA response. A second critical period for neonatal intestinal immune system development occurs at weaning time when the gut environment is exposed to new dietary antigens. Neonate needs to establish oral tolerance and in the absence of protective milk need to fight potential new pathogens. To improve knowledge about the immune response in the neonates, it is important to identify intrinsic and extrinsic factors which influence the intestinal immune system development and to elucidate their mechanism of action.

Abstract
Irritable bowel syndrome (IBS) is a common condition characterized by abdominal pain or discomfort, bloating, and altered stool form and passage. Small intestinal bacterial overgrowth (SIBO) is a condition in which there is overgrowth of bacteria in small bowel in excess of 105 colony forming units per milliliter on culture of the upper gut aspirate. Frequency of SIBO varied from 4%-78% among patients with IBS and from 1%-40% among controls. Higher frequency in some studies might be due to fallacious criteria [post-lactulose breath-hydrogen rise 20 PPM above basal within 90 min (early-peak)]. Glucose hydrogen breath test (GHBT) has a low sensitivity to diagnose SIBO. Hence, studies based on GHBT might have under-estimated frequency of SIBO. Therefore, it is important to analyze these studies carefully to evaluate whether the reported association between IBS and SIBO is over or under-projected. This review evaluates studies on association between SIBO and IBS, discordance between different studies, their strength and weakness including methodological issues and evidence on therapeutic manipulation of gut flora on symptoms of IBS.

Abstract
Breath analysis is becoming increasingly established as a means of assessing metabolic,
biochemical and physiological function in health and disease. The methods available for
these analyses exploit a variety of complex physicochemical principles, but are becoming
more easily utilised in the clinical setting. Whilst some of the factors accounting for
the biological variation in breath metabolite concentrations have been clarified, there
has been relatively little work on the dietary factors that may influence them. In
applying breath analysis to the clinical setting, it will be important to consider how
these factors may affect the interpretation of endogenous breath composition. Diet may
have complex effects on the generation of breath compounds. These effects may either be
due to a direct impact on metabolism, or because they alter the gastrointestinal flora.
Bacteria are a major source of compounds in breath, and their generation of H2,
hydrogen cyanide, aldehydes and alkanes may be an indicator of the health of their
host.
