Alcoholic liver disease (ALD) is one of the major global public health problems. yeast extract (ye)， a product prepared from yeast， has been proven to have antioxidant and anti-inflammatory properties. However， the potential role of ye in the prevention of ALD remains unclear. The present study aimed to investigate the protective effects of ye on ALD and explore the underlying mechanism based on gut microbiota. The result showed that ye supplementation significantly ameliorated chronic alcohol exposure-induced liver injury in mice. In addition， ye counteracted alcohol-induced gut dysbiosis， intestinal barrier dysfunction， lipopolysaccharide (LPS) leakage-induced inflammatory response in the liver. Moreover， microbiota depletion by a broad-spectrum antibiotic was sufficient to block the protective effect of ye on ALD， indicating the contribution of gut dysbiosis modulation to the hepatoprotective role of ye. Furthermore， we demonstrated the causal relationship between gut microbiota and hepatoprotective effects of ye with the fecal microbiota transplantation (FMT) experiment. Compared with the ALD-FMT mice， gut dysbiosis， intestinal barrier dysfunction， LPS/TLR4 signaling pathway activation， and liver inflammatory response were significantly improved in the ye-FMT mice. Together， our findings highlight that dietary ye protects against ALD through gut dysbiosis correction.

高级脂肪酸乙酯是引起酒体浑浊的关键因素之一。为系统分析白酒中的高级脂肪酸乙酯以改善白酒生产过程中的浑浊问题,建立了一种基于氨基化四氧化三铁(Fe_(3)O_(4)-NH_(2))磁性固相萃取结合气质联用技术的方法,用以同时测定白酒中8种高级脂肪酸乙酯。通过考察酒样的pH值、离子强度、吸附剂用量、吸附时间、解吸溶剂种类、解吸溶剂酸碱度、解吸时间等因素,确定了较佳的萃取条件。结果表明:这8种高级脂肪酸乙酯在各自的质量浓度范围内线性关系良好,相关系数R 2均大于0.99;方法检出限和定量限分别为9.1~42.9μg/L和5.2~200.0μg/L;回收率为79.6%~99.3%,相对标准偏差(n=3)为8.0%~10.7%。应用此方法,并结合同位素内标法对24种不同香型和品牌的白酒样品中8种高级脂肪酸乙酯进行精准定量,发现它们的种类和质量浓度存在显著差异。其中,在酱香型白酒中,高级脂肪酸乙酯的检出率最高,达到100%。该方法简便快捷,样品萃取只需10 min,具有高灵敏度和准确性,能够有效避免传统液-液萃取技术的背景干扰问题,可为实现白酒中高级脂肪酸乙酯的精准检测提供一种新的方法。

企业风险承担水平是构成企业核心竞争力的重要因素,在现代企业管理中扮演着重要角色。本文以2007—2021年沪深A股中交叉持股的上市公司数据为样本,构建加权的交叉持股网络,考察其对上市公司风险承担水平的影响。研究结果表明,企业越处于网络的中心位置,结构洞丰富度越高,其风险承担水平越高。机制检验发现,交叉持股网络主要通过缓解融资约束和提升信息披露质量来提高企业风险承担水平。调节效应发现,非国有企业、市场化水平较低地区的上市公司的交叉持股网络对其风险承担水平的提高作用更显著。异质性分析表明,度数中心性与中介中心性对上市公司风险承担水平的影响更为明显;对于处于成长期的上市公司,交叉持股网络更能提高风险承担水平。本文深入探讨了交叉持股网络对企业风险承担水平的影响机制及作用路径,为企业从交叉持股网络视角寻求发展动力、增强核心竞争力提供实践指引。

深层油藏储层埋藏深、厚度大,油井难以钻穿整个油层。针对深层油藏油柱高度的计算问题,考虑在油井投产后从油水界面到井底的垂向传热过程,建立了一个深层油藏传热模型。利用变量代换、分离变量及傅里叶变换等方法对模型进行了求解,获得了油藏油柱高度计算式。只需利用油井投产前和投产一段时间后的井底温度数据,便可计算油柱高度。以塔里木盆地某深层油藏某油井为例,展示了油柱高度的计算与应用。同时,利用该井的基础数据,代入传热模型,模拟计算了油井投产后不同时间下不同油层位置的温度值和温度梯度值,进而绘制了不同生产时间下储层温度分布曲线和不同储层位置处的储层温度动态变化曲线,结果表明油井投产后的储层温度分布呈非线性的动态变化特征。建立的传热模型可为深层油藏油柱高度的计算提供技术支持。
