Mastitis is a common disease for mammals all around the world. Figuring out why mastitis mainly occurs around parturition may be helpful for dealing with the disease. Lipolytic activity and oxidative stress take place around parturition, which may leads to alteration in fatty acids profile and proinflammatory cytokine expression. Thus, the aim of the present study was to further our understanding about the high incidence of mastitis around parturition by comparison of plasma fatty acid profile and mammary inflammation indicators at different reproductive stages. A total of 47 female rats were included in the present study. After mating, all the pregnant and non-pregnant rats began to receive the same experimental diet. Blood samples were collected at day 1 and 14 of gestation as well as day 3 *** samples were collected at day 14 of gestation and day 3 postpartum from pregnant and nonpregnant rats. The results showed that rats at d 3 postpartum had greater(P < 0.05) plasma concentrations of non-esterified fatty acids(NEFA), arachidonic acid(ARA) and docosahexaenoic acid(DHA) as well as ARA: eicosapentaenoic acid(EPA) ratio than those at d 14 of gestation. The mRNA abundances of interleukin-1 β(IL-1β), tumor necrosis factor-α(TNF-α),IL-8 and xanthine oxidoreductase(XOR) in mammary of the pregnant rats were greater(P < 0.05) than those in age-matched non-pregnant *** at d 3 postpartum had higher(P < 0.05) protein expression levels of IL-1β and TNF-α as well as meloperoxidase(MPO) activity and polymorphonuclear neutrophils(PMN) prevalence than those at d 1 of gestation. The rats at d 3 postpartum also had greater(P < 0.05) IL-1β and MPO activity than those at d 14 of gestation. The results indicated that elevated mammary expression of proinflammatory cytokines and XOR as well as altered fatty acid profile around parturition might facilitate the recruitment of neutrophils into mammary glands.

黑岛传治虽然长期以来被评论界认为是日本近代无产阶级反战文学的代表人物,但其反战文学的价值并没有得到深入解读。其文本中,始终存在着基于阶级视角和个体人性视角的两条批判战争的思路。他基于自身经历自觉选择了无产阶级的阶级立场。宫本显治等人对黑岛反战文学缺乏阶级性的批判是偏颇的。在《武装的街巷》中,由于跨越民族—国家立场的阶级连带感在文中并没有完全实现,使得从阶级视角出发的"战争"批判出现裂痕,而这一裂痕通过个体人性视角得以弥补。黑岛的反战文学之所以能兼具这两种视角,是由于其对"文学"本质的深层认知以及对社会底层个体的真切关怀。

以审判为中心的诉讼制度改革要求在审前程序中加强侦诉合力,以增强追诉的有效性与合法性。在诸多改革方案中,以"侦诉一体化"改造我国审前侦诉关系之构想,不仅在法理上缺乏充足依据,而且域外实践亦证明其不可行。相比之下,在我国既有的警检分立基础上构建"检察引导侦查"机制不失为更加合理的选择。为此,我国应当以高阶位法律的形式为其提供法律依据,并在厘清其性质定位的基础上,明确其适用的案件范围、引导侦查的主体、时间和具体方式。

21世纪初美国华裔文学的一个创作热点是针对南京大屠杀的书写。自2005年至2012年间,《紫金山燃烧之时》《金陵十三钗》《南京安魂曲》和《南京大屠杀:诗歌》等四部作品相继问世这些作品的涌现与华裔作家及历史学家张纯如密切相关。她的纪实文献《南京大屠杀:第二次世界大战中被遗忘的大屠杀》为华裔作家们提供了详实的史实素材,而她本人因揭露南京大屠杀暴行而经历的不幸也引起作家们的共情。在南京大屠杀面临见证危机的紧要关头,这些作品从施暴者、受难者、救援者和见证者等多个视角还原大屠杀全貌,成为见证那段历史的珍贵文献,警醒世人莫忘南京大屠杀。

黑岛传治以1929年末的中国之行为素材,创作了多篇涉及中国的反战作品。在中国之行之前,其反战文学思想已经形成以对底层民众的关怀为出发点、以无产阶级视角为特征的较成熟的体系。以中国之行为基础撰写的系列作品集中体现了黑岛反战文学思想的这些特性。从阶级视角出发,黑岛传治深刻揭露了日军侵略行径的实质,但其对日军普通士兵表现出的“平庸之恶”缺乏足够的批判深度,且对“中东铁路事件”中的苏联形象有所偏袒和拔高。同时,“中国体验”也使黑岛传治发现了反战思想中阶级视角所不能囊括的复杂层面,由此,其作品中亦出现了对战争中民族一国家视角、社会边缘群体等的描写,其反战文学也体现出了多面性和张力。

This study was conducted to investigate the effects of spray-dried porcine plasma protein(SDPP)or spray-dried chicken plasma protein(SDCP)supplementation in diets without the inclusion of antibiotics and zinc oxide(ZnO)on growth performance,fecal score,and fecal microbiota in early-weaned piglets.A total of 192 healthy weaning piglets(Duroc×Landrace×Yorkshire,21 d old)were blocked by BW(6.53±0.60 kg)and randomly assigned to 4 dietary treatments:negative control(NC,basal diet),positive control(PC),basal diet+ZnO at 2 g/kg and antibiotics at 0.8 g/kg,SDPP(containing 5%SDPP),and SDCP(containing 5%SDCP).The experiment lasted 14 *** SDPP group had higher(P<0.05)final BW,average daily gain and average daily feed intake than the NC and SDCP *** percentage of piglets with fecal scores at 2 or≥2 was higher(P<0.05)in the NC and SDCP groups than in the PC group.A decreased(P<0.05)bacterial alpha diversity and Bacteroidetes abundance,but increased(P<0.05)Firmicutes abundance were observed in the PC and SDPP groups when compared to the NC *** relative abundance of Lactobacillus was higher(P<0.05)in the SDPP than in the SDCP group,and that of Streptococcus was higher(P<0.01)in the PC and SDPP groups than in the NC *** PC group also had higher(P<0.01)Faecalibacterium abundance than the NC and SDCP ***,the SDCP group had higher(P<0.05)serum urea nitrogen than those fed other diets,and lower(P<0.10)shortchain fatty acids to branched-chain fatty acids ratio than the PC and SDPP ***,SDPP was a promising animal protein for piglets in increasing feed intake,modifying gut microbiota profile,reducing gut protein fermentation and alleviating diarrhea frequency,thus promoting growth performance,under the conditions with limited in-feed utilization of antibiotics and ZnO.
