异体造血干细胞移植问题、发展与思考

异体造血干细胞移植(Allo-HSCT)已成为治疗恶性血液病及其他各种疾病的有效方法之一。在Allo-HSCT中由于供体和受体免疫屏障的存在。从而一开始就是一个供受体矛盾的对立统一的过程。对其中矛盾的研究和解决充满了辩证唯物的哲学思想。也促使Allo-HSCT技术不断发展。新的方法和理念不断出现。使Allo-HSCT治疗白血病的疗效不断提高。     

退步原来是向前

从契此的“手把青苗插满田,低头便见水中天,六根清净方为道,退步原来是向前”偈中,反映了退让并不是完全的消极,有时反而是一种积极的进取,从而揭示出丰富的人生哲理。     

苏辙“示疾而病”的禅学思想

＂多病则与学道者宜,多难则与学禅者宜＂,苏辙却因有＂喜汝因病悟,或免终身著＂的示疾而病的禅学思想。＂示疾而病＂的苏辙以维摩自喻,在深层意义上,是他借维摩诘而表现其忧以天下、以乐天下的人格理想。     

试论卫生与法律的关系

卫生是人类重要的社会实践活动。卫生也是保护人体健康的重要社会事业,需要法律的保护和导向。卫生法为卫生发展提供了良好的社会环境,并控制医药卫生无序、失控及异化带来的社会危害性,造福人类,促进经济发展和社会进步。     

The bioethical structure of a human being

Bioethical debates such as those surrounding the manipulation of human embryos are often based on metaphysical assumptions that lack a foundation in the natural sciences. In this paper we support a gradualist position whereby the embryo progressively takes on the form and associated ethical significance of a human being. We support this position by introducing a concept of biological structure or form to show how the gradualist position has its metaphysical foundations in modern biology. The conceptual basis for form and structure are outlined and their compatibility with and basis in current empirical biology is demonstrated by some recent advances in our understanding of the processes of development from single cell to organism. We then briefly explore the ethical significance of accepting a form or structure based conception of biology for the status of the early embryo.     

Social Representations of Human Rights Amongst Czech University Students

The Universal Declaration of Human Rights is a general legislative framework for democratic societies. Studying the social representations of these basic human rights helps to explain how people understand and assess the basic rights and how these rights relate to everyday life. Over 400 Czech university students rated the 30 articles of the Declaration of Human Rights on various scales (degree of understanding, personal relevance, consequences for individual responsibility, for government, political parties, etc.). A semantic space was identified in which concepts (i.e. the Articles of the Declaration) could be located. A typology (clusters) of articles was then established within that semantic space. A factor analysis of the scales resulted in a two-dimensional solution (‘positive attitude’ and ‘personal influence’). Five clusters of assessed articles were identified within this semantic space.

Meaning Selection and the Subcortex: Evidence of Reduced Lexical Ambiguity Repetition Effects Following Subcortical Lesions

Recent research indicates that individuals with nonthalamic subcortical (NS) lesions can experience difficulties processing lexical ambiguities in a variety of contexts. This study examined how prior processing of a lexical ambiguity influences subsequent meaning activation in 10 individuals with NS lesions and 10 matched healthy controls. Subjects made speeded lexical decisions on related or unrelated targets following homophone primes. Homophones were repeated with different targets biasing the same or different meanings on the second presentation. The effects of prime-target relatedness, interstimulus interval (200 or 1250 ms), and same vs. different meaning repetition were examined. Both the patient and control groups showed priming when the same homophone meaning was biased on repetition. When a different meaning was biased on the second presentation, no priming was evident in the controls, while facilitation remained present for the NS group, consistent with aberrant meaning selection and deactivation processes. These findings are discussed in terms of age and task-related repetition effects and current conceptions of frontal–subcortical involvement in cognition.David Copland is supported by the Australian Research Council     

Hemispheric contributions to lexical ambiguity resolution: evidence from individuals with complex language impairment following left-hemisphere lesions

Nine individuals with complex language deficits following left-hemisphere cortical lesions and a matched control group (n = 9) performed speeded lexical decisions on the third word of auditory word triplets containing a lexical ambiguity. The critical conditions were concordant (e.g., coin-bank-money), discordant (e.g., river-bank-money), neutral (e.g., day-bank-money), and unrelated (e.g., river-day-money). Triplets were presented with an interstimulus interval (ISI) of 100 and 1250 ms. Overall, the left-hemisphere-damaged subjects appeared able to exhaustively access meanings for lexical ambiguities rapidly, but were unable to reduce the level of activation for contextually inappropriate meanings at both short and long ISIs, unlike control subjects. These findings are consistent with a disruption of the proposed role of the left hemisphere in selecting and suppressing meanings via contextual integration and a sparing of the right-hemisphere mechanisms responsible for maintaining alternative meanings.
