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.

The symptoms of allergic airway disease are impacted by the interplay of gut microbiota， which may be modulated by probiotics. This study aimed to investigate the potential anti-inflammatory effects of three lactic acid bacteria (LAB) on allergic asthma through modulation of the gut microbiota. Ovalbumin (OVA)-induced asthmatic mice were treated with three LAB strains， and their gut microbiota profiles were analyzed using 16S rRNA sequencing. Fecal microbiota transplantation (FMT) from mice fed with Lactobacillus rhamnosus RL-H3-005 was administered to OVA-induced asthmatic mice. The results demonstrated that RL-H3-005 effectively reduced inflammatory infiltrates in the lung and colon， as well as suppressed cytokine levels associated with allergic asthma compared to other strains. In addition， the supplementation of RL-H3-005 modulated the composition of gut microbiota in mice with allergic asthma. FMT results further supported the notion that modulating the gut microbiota with RL-H3-005 plays a crucial role in attenuating airway inflammatory symptoms in allergic asthma.

不同语言的情绪感知会引发决策偏差,但目前尚无研究考察这种偏见如何影响社会顺应。本研究采用随机点运动任务,通过“初始判断—同伴反馈—再次判断”的实验程序,探讨不同语言的情绪性评价对社会顺应的影响。结果发现:(1)母语消极反馈比第二语言消极反馈更容易诱使个体改变之前的判断,表现出顺应行为;(2)个体的顺应行为受到任务不确定性的调节。整个研究说明,不同语言的情绪性评价会影响个体的社会顺应行为。

目的研究TP439不锈钢在高温水蒸气环境中的应力腐蚀开裂行为,并探讨水蒸气和温度对其应力腐蚀开裂敏感性的影响规律。方法采用慢应变速率拉伸试验方法研究了TP439不锈钢在400~600℃水蒸气环境中的应力腐蚀开裂行为,利用SEM和EDS分析试样断口区域的形貌及元素分布。结果同一应变速率(2×10^(-5) s^(-1))下,随着温度在400~600℃范围内升高,TP439不锈钢在空气和水蒸气环境中的屈服强度、抗拉强度和断裂能均逐渐降低,延伸率逐渐增大。400℃和500℃时,试样在水蒸气环境中的抗拉强度较空气环境中有所降低,而延伸率较空气环境中增大。600℃时试样在水蒸气环境中的力学性能较空气环境中无明显差别。试样在400、500、600℃水蒸气环境中的应力腐蚀开裂敏感性指数分别为0.7%、1.2%和-2.8%,应力腐蚀开裂敏感性较低。试样在400~600℃水蒸气环境中的断口均呈现韧性断裂特征,断口形貌整体由韧窝和微孔组成,颈缩现象显著,断口附近未发现二次裂纹。温度在400~600℃范围内升高时,断口的韧窝特征更加明显,颈缩程度逐渐增大,600℃时断口侧面的氧化膜表面Cr含量明显降低,主要由Fe的氧化物形成。结论水蒸气对TP439不锈钢的应力腐蚀开裂行为起促进作用。基于应力腐蚀开裂敏感性指数和断口的分析,在应变速率为2×10^(-5) s^(-1)的400~600℃水蒸气环境中,TP439不锈钢的应力腐蚀开裂敏感性较低。
