乳及乳制品的脂肪酸(FAs)构成模式,即FAs指纹,不仅受物种来源、自然地理和气候环境决定或影响,还与家畜饲养方式、原乳质量、加工类型、加工标准和工艺参数等人为和工业因素有关。目前尚未提出乳制品"工业指纹"概念,也缺乏相应系统的研究。采集荷斯坦牛、牦牛和山羊原乳、超高温灭菌(UHT)乳和乳粉样品200份,采用气相色谱法测定FAs,按照①加工类型;②UHT处理;③厂家/品牌;④液态乳品类(品系)和⑤饲养模式5类工业因素,对FA单指标和FAs多指标整体进行统计比较,通过主成分分析(PCA)观察样品的FAs指纹自然聚类情况。结果表明,多数FA在5类研究中都存在显著差异,而配伍方差和配对t检验FAs差异都不显著,说明传统统计不能区分FAs模式复杂的整体改变。PCA分析样品集的自然聚类与各加工处理、品牌品类及饲养模式一致,说明各工业因素对乳品FAs指纹都有特征性和模式化的影响。有望利用FAs指纹实现乳品生产加工方式、厂家品牌及品类等级等的区分,市售乳品完整性和真实性判别,奶畜科学饲养及功能性特色乳品研发效果多指标大数据的可视化评价。

含气土的储藏气压与细观结构表征是研究浅层气地质灾害的关键因素。利用工业CT扫描测试系统,采用立式旋转扫描,微焦点X射线光源的位置固定,样品沿XY平面方向匀速旋转1周,设定旋转步长为0.3°/s,对反应釜内含气样品注气加压至2 MPa、4 MPa、6 MPa,充分考虑样品成像最佳分辨率、最佳探测范围等因素的影响。结果表明,CT扫描获得的切片图像与重构图像具有良好的实验效果;加压注气到2 MPa时,小气泡灰度值增加;加压到6 MPa时气体整体灰度值增加明显;增压过程中气泡数量随着气泡半径增加而减少;加压注气过程会导致固−液−气三相物质局部变化,表现为孔隙气、孔隙水的体积变化幅度整体大于土骨架,微观局部位置会有较大的升高或降低。当不同位置的气体含量上升且占据主导地位时,会驱动着孔隙水的减少与土骨架的移动。

肾性贫血(renal anemia,RA)是慢性肾衰竭(chronic renal failure,CRF)患者较常见的并发症之一,大多数患者均伴有轻或中度贫血。评估慢性肾衰患者血液常规,做到三早一少:早发现、早诊断、早治疗、少伤害,对降低肾性贫血的发生率和改善患者病情尤为关键。将中医“治未病”理论应用于肾性贫血的防治上,从主要中医思想出发即:未病先防:重在调情志,节饮食、甚起居,善养生,适当运动,改善不良体质增强机体正气,从而达到阴平阳秘、预防疾病目的;既病防变:对于肾性贫血发病者,稳定肾功能的基础上,予以中医药及中西医结合等方式积极治疗贫血,增强患者体质,提高慢肾衰患者的生活质量。
