In previous experiment, we isolated a compound dibutyl phthalate （DBP） from Vaccaria segetalis which had galactopoietic function on mammary gland epithelial cells of dairy cow （DCMECs）. In this experiment, we ascertained the metabolic regulation function of DBP on DCMECs. Many genes related to lactation including Stat5, AMPK, b-casein, Glut1, SREBP-1, PEPCK, and ACC were detected by real-time PCR. Furthermore, Stat5 and AMPK were detected by Western blot and immunofluorescence co-localization, respectively. The results showed that DBP stimulates the expression of Stat5 and p-Stat5, thus activates Stat5 cell signal transduction pathway and stimulates b-casein synthesis. DBP also raises the activities of Glut1 and AMPK to stimulate glucose uptake and glycometabolism and activates the expression of AMPK downstream target genes PEPCK and ACC and expression of SREBP-1 to stimulate milk fat synthesis. In addition, the activities of HK, G-6-PDH, ICDH, ATPase, and energy charges were stimulated by DBP to increase the energy metabolism level of DCMECs. The results showed DBP stimulates energy metabolism related to galactopoietic function in DCMECs.

liquidus temperatures in the molten salt system Na3AlF6-K3AlF6-AlF3 of interest for aluminum electrolysis were determined by thermal analysis method. The results were presented and an empirical equation describing liquidus temperatures for primary crystallization was derived t=1003.5–0.081×A2.3159–5.87×B0.657–0.024×A2.22×B1.14＋ 0.035×A2.17×B1.084, where t is the liquidus temperature in degree Celsius, A denotes the mass fraction of AlF3 in system Na3AlF6-K3AlF6- AlF3, and B denotes K3AlF6/（Na3AlF6＋K3AlF6 ） in mass（%, the value was defined as KR in this paper）. The composition limitations are 0w（AlF3）30%, and 0KR50%. The isothermal diagram of molten salt system Na3AlF6-K3AlF6-AlF3 was obtained in this composition limitation.

由于国内外食品市场准入制度和溯源体系不完善,销售商乱用虚假标签等现象的发生,使得食品安全形势愈发严峻。为了保障野生食用菌的安全性,保护云南高原特色农业品牌战略,亟需建立快速准确的产地溯源方法。通过采集云南及其周边8个产地、79个绒柄牛肝菌子实体的紫外-可见吸收光谱(UV-Vis)与傅里叶变换红外光谱(FTIR),采用多元散射校正(MSC)、标准正态变换(SNV)、二阶导数(2D)、平滑(SG)等算法对原始光谱进行预处理。基于低级与中级数据融合策略,将预处理后的UV-Vis与FTIR光谱信息进行融合,结合偏最小二乘判别分析(PLS-DA)与支持向量机(SVM),建立牛肝菌产地鉴别模型,确定最佳产地溯源方法。对光谱融合数据进行系统聚类分析(HCA),探讨不同产地样品整体化学信息的差异性与相关性。结果显示:(1)采用MSC+2D和SNV+2D对UV-Vis与FTIR光谱进行预处理,R^2Y与Q^2最大,分别为61.58%,95.09%和50.85%,82.16%,表明MSC+2D与SNV+2D为UV-Vis与FTIR光谱的最佳预处理方法;(2)基于UV-Vis,FTIR,低级与中级数据融合建立的PLS-DA与SVM模型,样品分类错误总数分别为24,6,2,2和6,1,1,0,表明数据融合模型分类效果优于单一UV-Vis与FTIR模型;(3)中级数据融合模型中,SVM对所有样品的分类全部正确,PLS-DA的分类错误总数为2,表明基于SVM的中级数据融合策略分类效果优于PLS-DA;(4)低级和中级数据融合HCA模型,分别有4和1个样品不能与同一类区域样品聚为一类,表明中级数据融合优于低级数据融合;由中级数据融合HCA图可知,同一产地样品聚类距离小于不同产地之间聚类距离,表明同一产地样品整体化学成分类较相似,且同一产地不同采集地点的差异小于不同产地之间的差异。采用UV-Vis与FTIR光谱中级数据融合策略结合SVM,能够对不同产地来源牛肝菌样品进行准确鉴别,为野生食用菌产地溯源研究提供一种新方法。
