消化性溃疡研究的若干进展 总被引:3,自引:1,他引:2
姚宏昌 《医学与哲学(人文社会医学版)》2010,(5):8-10,15
消化性溃疡是世界性人类消化系统中常见病之一。随着人们对本病广泛而深入的研究,在基础和临床方面都取得突破性进展。在消化性溃疡发病机制中,由于H.Pylori的发现,使这古老的疾病,赋予了现代的概念,并使得消化性溃疡的治疗发生了重大的变革。目前已有多种H2-RA、PPI类药物治疗消化性溃疡,但其高复发率仍待解决。为提高溃疡愈合质量(Quality of ulcer healing),黏膜保护剂的研发和应用方兴未艾。从分子机制探讨消化性溃疡的病因,人们已发现一些与之相关的基因。相信基因疗法将为治疗消化性溃疡带来飞跃性的发展,应用相关基因编码产物,有望从根本上治愈消化性溃疡。 相似文献

This paper is a review of the work that has been carried out on machine consciousness. A clear overview of this diverse field is achieved by breaking machine consciousness down into four different areas, which are used to understand its aims, discuss its relationship with other subjects and outline the work that has been carried out so far. The criticisms that have been made against machine consciousness are also covered, along with its potential benefits, and the work that has been done on analysing systems for signs of consciousness. Some of the social and ethical issues raised by machine consciousness are examined at the end of the paper. 相似文献

After expressing gratitude to each contributor, and briefly commenting on each, I probe several main themes of my work, addressing the question of the apparent difference between my earlier philosophical and later clinical writings. Central to both is the reflexivity of the human agent, and that each exhibits a form of practice regardless of the specific aims embedded in each. I then address the theme of narrative writing as my work has developed over the past several decades – at the heart of which are questions of self and integrity. 相似文献

1 蛋白质组研究的必要性与艰难性首先 ,目前基因组研究的策略虽然能从基因转录的水平 ,即mRNA水平来说明一种蛋白质表达所须启动的基因状况 ,从而在程度上反映蛋白质水平。但事实上 ,一种基因并不仅仅对应于一种蛋白质 ,而可为几个 ,甚至几十个 ,因为大多数mRNA只能编码蛋白质的前体蛋白 ,后者在不同的时间、空间 ,经过特定地剪切、加工、修饰、折叠、转运、定位等 ,才能成为一个有正常功能的蛋白质。这些过程中的任何一个步骤发生微细的差错即可导致异常蛋白质的产生和疾病。而基因是不能完全决定这样复杂的蛋白质后期活动的。其… 相似文献

Substantial evidence in the behavioral and social sciences has accrued in support of numerous intervention programs and policies bearing on improving the lives of children and families. To this end, Clinical Child and Family Psychology Review features a special journal issue on “Evolving Toward a More Nurturing Society.” The field has achieved numerous advances regarding how to create and promote nurturing environments that foster successful development and prevent psychological and behavioral problems in children and youth. Such advances cut across multiple strategies (e.g., programs and interventions, practices, and public policies), settings (e.g., family, school including preschool and K-12, service sectors, community), domains (e.g., behavioral health, parenting, cognitive and academic functioning, nutrition, physical activity, obesity, safety, and many other domains), and developmental periods of childhood. The special journal issue showcases a sampling of strategies and domains relevant to producing optimal conditions of nurturance for children and families. 相似文献

代词的指代在语篇局部连贯性中具有关键作用。中心理论是代词指称中的重要理论,它解释了语篇中代词的分布规律;注意驱动理论是在中心理沦的基础上结合重音预设解释重音或非重音代词。影响代词指称的因素有语义因素和结构因素。对代词的认知研究另一方面主要集中在对歧义代词的解释.对歧义代词的解释的研究一方面采用重复姓名不利实验范式,另一方面的研究采用的研究方法是探测词任务。在汉语中对代词的研究主要是对文本语篇的研究。 相似文献

心理神经免疫学的新进展 总被引:16,自引:0,他引:16
心理因素对免疫的影响已经引起了研究者的特别关注。近两年心理神经免疫学研究会((Psychoneuroimmunology esearch ociety)每年召开一次世界性心理神经免疫学学术年会,而且在Entrez-PubMed和BioMedNet中,1985-2001年标题中含有psychoneuroimmunology的文章分别有130篇和131篇,文字中含有psychoneuroimmunology的文章有605篇,这些足见免疫学界对心理神经免疫问题的重视。 相似文献

Ephraim Kanarfogel 《Jewish History》2000,14(3):287-316
Intellectual historians have identified differing attitudes toward the notion of progress among the churchmen of the twelfth
and thirteenth centuries in western Europe. The present study aims to trace the views of rabbinic figures in medieval Ashkenaz
during this period. Tosafists such as Isaiah di Trani, Samson of Sens, and Asher b. Yehiel felt that subsequent teachers and
decisors could progress beyond the formulations and rulings of their predecessors, while Rashi and Rashbam believed that progress
within the post-Talmudic period, at least with respect to legal rulings, was virtually impossible. At the same time, there
was a consensus that the spirituality of earlier generations was greater, and that certain prerogatives in ritual matters
which were accepted in the earlier period were no longer valid. As in the Christian world, those who were partisans of progress
were criticized by others for their stance. Within the Sefardic orbit, Maimonides was virtually alone in his view that the
``decline of the generations' was not an inexorable process. Those Tosafists who agreed with this position were his nearest
contemporary allies. The application of dialectic by the Tosafists to justify existing Ashkenazic practices that appeared
to be contrary to Talmudic law parallels the activities of canon lawyers, as do their efforts to deal with new technologies.
Even the more conservative group of Ashkenazic rabbinic thinkers looked upon the idea of newness itself quite favorably.
