Introduction Adenomyoepithelioma （AME） is uncommon characterized by biphasic proliferation of both epithelial and myoepithelial cells. More than half of the adenomyoepitheliomas （AME） are benign, but in rare instances, it may become malignant. Malignant adenomyoepitheliomas almost always occur in the breast and salivary gland. They are unusual in vulva. We report this case and provide some information about symptoms, microstructure, treatment, and a discussion about this kind of disease.

In plants,glycerol-3-phosphate dehydrogenase(GPDH)catalyzes the interconversion of glycerol-3-phosphate(G3P)and dihydroxyacetone phosphate(DHAP)coupled to the reduction/oxidation of the nicotinamide adenine dinucleotide(NADH)pool,and plays a central role in glycerolipid metabolism and stress *** studies have focused mainly on the NAD+-dependent GPDH isoforms,neglecting the role of flavin adenine dinucleotide(FAD)-dependent *** isolated and characterized three mitochondrialtargeted FAD-GPDHs in soybean,of which one isoform(GmGPDH12)showed a significant transcriptional response to NaCl and mannitol treatments,suggesting the existence of a major FAD-GPDH isoform acting in soybean responses to salt and osmotic *** enzyme kinetic assay showed that the purified GmGPDH12 protein possessed the capacity to oxidize G3P to DHAP in the presence of *** and RNA interference of GmGPDH12 in soybean hairy roots resulted in elevated tolerance and sensitivity to salt and osmotic stress,respectively.G3P contents were significantly lower in GmGPDH12-overexpressing hair roots and higher in knockdown hair roots,indicating that GmGPDH12 was essential for G3P catabolism.A significant perturbation in redox status of NADH,ascorbic acid(ASA)and glutathione(GSH)pools was observed in GmGPDH12-knockdown plants under stress *** impaired redox balance was manifested by higher reactive oxygen species generation and consequent cell damage or death;however,overexpressing plants showed the opposite results for these ***12 overexpression contributed to maintaining constant respiration rates under salt or osmotic stress by regulating mRNA levels of key mitochondrial respiratory *** study provides new evidence for the roles of mitochondria-localized GmGPDH12 in conferring resistance to salt or osmotic stress by maintaining cellular redox homeostasis,protecting cells and respiration from oxidative injury.

With the increasing demand of electric power, transmission congestion becomes a popular phenomenon in power systems. In order to improve the ATC（Available Transfer Capability） between buses of the network, this paper proposes a location method of TCSC in power grid. Power transfer distribution factor and line outage distribution factor are used to build the mathematical model of ATC considering the N-1 security constraints. Meanwhile, the genetic algorithm is used to calculate the location and the capacity of TCSC. The proposed method is applied to the IEEE 14-bus system. The results show that this method can improve the ATC of power systems with TCSC obviously.

在线互助论坛塑造了一种全新的信息交流与意义交换的公共空间。在此嵌入式的虚拟社区内,用户共享集体身份,为某种共同目标所驱动,并在与他人的动态互动中累积社会资本,建构自身的话语策略。基于从网页抓取的在线抑郁症互助论坛公开数据,本研究建立了论坛内用户的回帖关系网络,力图从社会资本的结构性与建构性两个层面共同讨论用户在此场域内的交流互动。一方面,用户间讨论话题或集中于疾病信息的传递,或侧重于情感层面的沟通,而两种讨论的议题特性与用户可摄取的资源间存在关联:同参与信息讨论的用户相比,参与情感讨论的用户拥有更多的黏连社会资本与桥接社会资本,同时前者的回复分布较之后者更为偏态,资源更为集中。另一方面,用户建构自身求助话语的方式展现着其认知与心理过程,而这与他们所获得的社会支持间存在着显著关联:发帖中的非正式语言使用正向预测收到回复的数量;发帖中体现认知加工程度的语言使用与第一人称复数代词的使用正向预测收到回复的平均长度,而非正式词语的使用和情感正向性负向预测收到回复的平均长度。本研究为在线互助小组或论坛用户寻求支持和帮助提供了实际指导,也为我国推动"互联网+医疗"的发展目标提供参考。

随着人口老龄化的不断加剧,老年刻板印象威胁受到越来越多的关注。不同于种族或民族、性别等刻板印象威胁,老年刻板印象威胁表现出累积性、共通性与连续性等特征。目前关于老年刻板印象威胁的研究多集中于认知老化尤其是记忆老化上,关注老年刻板印象威胁对老年司机和老年员工的消极影响。消除与降低老年刻板印象威胁的消极效应可以从认知改变、群体认同、代际接触、老龄自我实现和个性化以及媒体宣传等五个方面来进行。在实验室研究中,老年刻板印象威胁有外显与内隐两种不同的操纵形式。未来可以从扩展研究领域、细化"年龄"差异、比较整体效应大小和性别差异、侧重积极效应以及加强本土化检验和跨文化比较研究等方面来深化。

实地调研作为分析师了解上市公司非公开信息的重要手段,对资本市场的效率提升发挥重要作用。利用2009年至2014年深交所上市公司相关数据,探讨分析师实地调研对年报市场反应的影响及其作用机理。研究发现:分析师实地调研提供的增量信息被投资者作为年报会计盈余的决策参考,实地调研确实提高了资本市场信息效率,信息效率的提升与调研次数显著正相关。进一步分组回归后发现,分析师调研发挥的信息沟通功能在公司信息环境较差的情况下较为明显;机构投资者以及流动性较强公司的投资者更能对分析师调研的增量信息做出回应,不同投资者利用分析师实地调研所提供信息优势的能力存在差别。
