为研究大肠杆菌对奶牛乳腺成纤维细胞(BMFB)TGF-β1表达的影响以及对其信号转导通路Toll样受体4(TLR4)的表达和核转录因子κB(NF-κB)活化的影响,采用热灭活的不同浓度大肠杆菌菌液(0、1×105、1×106、1×108 CFU/mL)作用于奶牛乳腺成纤维细胞,分别于不同时间点(作用后第6、12、24、48小时)运用实时荧光定量PCR(qRT-PCR)检测TGF-β1和TLR4mRNA的表达,运用Western-blot检测TGF-β1、TLR4和p-NF-κB-p65蛋白的相对表达量。结果显示,大肠杆菌作用BMFB后,TGF-β1mRNA和蛋白的表达量显著的升高,并且TGF-β1mRNA的表达呈明显的时效及量效关系,于第24小时达到高峰后降低(P<0.05);TGF-β1蛋白的表达量呈量效性(P<0.05)。TLR4mRNA和蛋白表达水平显著升高,并且TLR4mRNA和蛋白的表达呈时效性和量效性,分别于作用后第24和12小时达到最高后逐渐下降(P<0.05)。p-NF-κB-p65的表达与大肠杆菌作用浓度呈正量效关系,表达量随作用时间延长先升高后逐渐降低(P<0.05)。上述研究结果表明,热灭活的大肠杆菌能够促进BMFB的TLR4表达,并激活BMFB p-NF-κB-p65蛋白的表达,从而促进TGF-β1的表达。

HfO2-based ferroelectric field-effect transistor （FeF ET） has become a promising solution for next-generation embedded non-volatile memory （NVM） owing to its complementary metal-oxide-semiconductor （CMOS） compatibility,small footprint, high performance, and non-destructive readout [1]. Recent research of HfO2-based FeF ET has focused on the device operation mechanisms as well as reliability issues such as the interplay between polarization switching and charge trapping/detrapping [2], read-after-write latency [3] and endurance degradation [4]. It has been demonstrated that endurance higher than 1010cycles with negligible read-after-write latency is possible if the gate stack of FeF ET is well engineered [5].

为了解奶牛乳腺炎病例乳汁中白细胞介素-6(IL-6)与体细胞凋亡的相关性,探讨了患有不同程度乳腺炎的奶牛乳汁中IL-6水平变化,并研究了IL-6与乳汁体细胞凋亡的相关性。利用无菌消毒法对某奶牛饲养场的82头奶牛采集乳样,采用放射免疫分析法测定乳清IL-6,应用流式细胞仪检测乳汁体细胞凋亡率。结果表明,隐性乳腺炎乳汁中IL-6水平极显著高于无乳腺炎乳汁中IL-6水平(P<0.01),临床乳腺炎乳汁中IL-6水平极显著高于无乳腺炎乳汁和隐性乳腺炎乳汁中IL-6水平(P<0.01);奶牛乳腺炎病例乳汁中IL-6水平与上皮细胞、巨噬细胞、淋巴细胞和中性粒细胞凋亡呈明显负相关(P<0.01),其中IL-6与中性粒细胞的相关系数接近1或达到1,二者的相关性最明显,IL-6对中性粒细胞凋亡抑制最明显。奶牛乳汁中IL-6水平与奶牛乳腺炎的发病程度密切相关,IL-6不同程度的抑制牛乳汁中体细胞的凋亡过程,IL-6对中性粒细胞的凋亡过程的明显抑制与奶牛乳腺炎有重要关系。
