The internal microbial diversity and small molecular metabolites of Nuodeng ham in different processing years(the first,second and third year sample)were analyzed by high-throughput sequencing technology and gas chromatography-time of flight mass spectrography(GC-TOF-MS)to study the effects of microorganisms and small molecular metabolites on the quality of ham in different processing *** results showed that the dominant bacteria phyla of Nuodeng ham in different processing years were Proteobacteria and Firmicutes,the dominant fungi phyla were Ascomycota and Basidiomycota,while Staphylococcus and Aspergillus were the dominant bacteria and fungi of Nuodeng ham,***,252 kinds of small molecular metabolites were identified from Nuodeng ham in different processing years,and 12 different metabolites were screened through multivariate statistical *** metabolic pathway analysis showed that 23 metabolic pathways were related to ham fermentation,of which 8 metabolic pathways had significant effects on ham fermentation(Impact>0.01,P<0.05).The content of L-proline,phenyllactic acid,L-lysine,carnosine,taurine,D-proline,betaine and creatine were significantly positively correlated with the relative abundance of Staphylococcus and Serratia,but negatively correlated with the relative abundance of Halomonas,Aspergillus and Yamadazyma.

Punicalagin has been demonstrated to exhibit anti-oxidant and anti-inflammatory properties， but whether and how it could impact hypercholesterolemia remains not fully explored. The aim of this study was to investigate the influence of punicalagin on hypercholesterolemia in mice and its related mechanisms. After 6 weeks’ intervention， punicalagin significantly reduced serum total cholesterol and low density lipoprotein cholesterol (LDL-C) levels in mice fed a high-fat high-cholesterol (HFHC) diet. Meanwhile， punicalagin supplementation lowered hepatic cholesterol level， which corresponded to the down-regulation of cholesterol synthesis genes (Fdps， Cyp51) and up-regulated bile acid synthesis genes (Cyp7a1， Cyp27a1). In addition， bile acid reabsorption was retarded in punicalagin-fed mice through down-regulating ileal apical sodium-dependent BA transporter (ASBT). Furthermore， intestinal farnesoid X receptor (FXR)-fibroblast growth factor 15 (Fgf15) pathway was inhibited while hepatic FXR-small heterodimeric partner (SHP) pathway was activated in punicalagin group. Microbiota analysis and targeted metabolomics showed that punicalagin decreased the abundance of bile-salt hydrolase (BSH)-producing bacteria (Clostridiaceae and Bifidobacteriaceae) and the ratio of primary BAs to secondary BAs. In conclusion， the cholesterol-lowering effect of punicalagin partly through down-regulating cholesterol synthesis and increasing cholesterol catabolism， which could be achieved by regulating gut microbiota， altering bile acid composition and modulating FXR signaling pathway. These findings indicate the potential application of punicalagin-related products as an alternative strategy for hypercholesterolemia prevention and mitigation.

Lactobacillus rhamnosus MP108 alleviates ulcerative colitis in mice by enhancing the intestinal barrier， inhibiting inflammation， and modulating gut microbiota

作者： Huizhen Li Yang Chen Huiting Fang Xinmei Guo Xuecong Liu Jianxin Zhao Wei Chen Bo Yang State Key Laboratory of food Science and Resources Jiangnan University School of food Science and Technology Jiangnan University Jinqiao Biotechnology Co. Ltd. Huai'an Jiangsu China National Engineering research center for Functional food Jiangnan University International Joint research center for Probiotics & Gut Health Jiangnan University

Ulcerative colitis (UC) is a long-term inflammatory disorder that has evolved into a worldwide challenge. The development of new therapies against UC is imperative as all current therapies for UC are flawed in some way. Thus， the present study aimed to assess the palliative effects of Lactobacillus rhamnosus MP108 on UC in mice and to explore its potential mechanisms. The results showed that L. rhamnosus MP108 ameliorated the symptoms of UC， including preventing body weight loss， DAI elevation， and colon shortening， and attenuated colonic pathological damage. L. rhamnosus MP108 dramatically increased the number of goblet cells， MUC2 level， and tight junction protein level in the colon and remarkably inhibited epithelial cell apoptosis， thereby strengthening the intestinal barrier. L. rhamnosus MP108 pronouncedly diminished pro-inflammatory cytokine levels and strikingly augmented anti-inflammatory cytokine levels， in turn suppressing inflammation. Furthermore， L. rhamnosus MP108 conspicuously boosted the proportion of short-chain fatty acids (SCFAs) producers in gut microbiota， contributing to increased levels of acetate and butyrate. Therefore， L. rhamnosus MP108 might alleviate UC via improving the intestinal barrier， inhibiting inflammation， and modulating intestinal microbiota.
