生殖性复制与医疗性复制之伦理区分

目前,各国政府和学术界对生殖性复制持否定态度是一致的,但对医疗性复制却存在激烈的争论。争论主要涉及人类胚胎的来源、胚胎的地位,以及胚胎干细胞成果应用的可接受性。     

人类干细胞研究的伦理学争论

关于干细胞研究的伦理学争论越来越成为热门话题。2000年8月23日,美国卫生研究所颁布了涉及人类多能胚胎干细胞研究的指南。指南允许联邦政府资助的研究者进行干细胞研究,但是按照布什总统2001年8月9日的决定,政府只资助有限制的干细胞研究。而在英国、法国、日本、澳洲、以及其他国家,干细胞研究不仅在私人的实验室里而且也在政府的实验室里进行着。无论如何,人类干细胞研究应该按照一定规范谨慎进行。     

人类胚胎干细胞的伦理学应用

人类胚胎干细胞研究和使用面临很多问题,并且大部分已经进行了广泛的讨论,但目前仍有一些问题很少进行讨论。对这些问题的讨论将有助于更好地研究人类胚胎干细胞的使用问题,这些问题是：（1）干细胞研究与社会政策,各个国家有关的政策制定并不一致,除了禁止人的生殖性克隆的国际性公约外,国际性准则在胚胎研究的也没有提供明确的规定;（2）欧洲有些国家在相关的问题的立法一致性上存在着许多问题,有些甚至是相互预报的;（3）干细胞研究应用的预防原则的适宜性问题已引起人们的争论;（4）有利及避免浪费原则在干细胞研究中的应用。     

Cross‐Species Chimeras: Exploring a Possible Christian Perspective

Various entities that combine material from humans and other animals at either the cellular or subcellular level have attracted growing public interest. I explore the controversy by considering both the scientific rationale behind creating various entities that have prompted the greatest public concern and possible ethical implications. I note a number of potentially relevant biblical passages and reflect on the imago Dei and considerations of telos in order to prompt wider discussion regarding how Christians might respond to such emerging bioethical issues.     

Patenting humans: Clones,chimeras, and biological artifacts

The momentum of advances in biology is evident in the history of patents on life forms. As we proceed forward with greater understanding and technological control of developmental biology there will be many new and challenging dilemmas related to patenting of human parts and partial trajectories of human development. These dilemmas are already evident in the current conflict over the moral status of the early human embryo. In this essay, recent evidence from embryological studies is considered and the unbroken continuity of organismal development initiated at fertilization is asserted as clear and reasonable grounds for moral standing. Within this frame of analysis, it is proposed that through a technique of Altered Nuclear Transfer, non-organismal entities might be created from which embryonic stem cells could be morally procured. Criteria for patenting of such non-organismal entities are considered. An earlier version of this paper was presented at an international conference, “The Ethics of Intellectual Property Rights and Patents,” held in Warsaw, Poland on 23–24 April, 2004.     

“无主胚胎”的处理方式及其伦理争论

随着辅助生殖技术的不断发展,越来越多暂时不需要进行移植的胚胎存放在生殖医学中心.然而,由于各种伦理争议及社会舆论压力,生殖中心往往会困惑于“无主胚胎”的处理.2013年6月,美国生殖医学协会伦理委员会对“无主胚胎”进行了确切的定义并给出了处理意见和指导原则,结合我国实际国情,从“无主胚胎”定义、“无主胚胎”现状、“无主胚胎”的处理方式及伦理争议、对生殖中心的建议四个方面进行阐述,以求为生殖中心在“无主胚胎”处理方面提供相应帮助.     

人文关怀在消除IVF—ET患者心理压力中的作用

近年我国不少生殖医学中心在如何提高体外受精一胚胎移植（IVF—ET）治疗成功率问题上,都将注意力集中在临床用药的研究、控制性超促排卵方案的改进以及实验室条件的改善上,大多忽视IVF—ET患者心理方面的治疗。有研究表明：IVF—ET治疗的成功,不仅与患者自身的病理及生理状况有关,更与患者在治疗过程中产生的心理压力有关。因此,建议医护人员在给不孕症患者实施IVF-ET助孕治疗的全过程中,应给予患者更多人文关怀,这样不仅能够减少IVF—ET患者心理健康问题的发生,而且可以改善患者的身心状态和应对治疗能力,从而提高IVF—ET治疗成功率。     

慢性粒细胞白血病治疗方案选择的分析

随着对慢性粒细胞白血病（CML）发病机制研究的深入,在细胞遗传学基础上引入了分子生物学技术,使CML的治疗提高到了个体化、系统化的新阶段。结合现代新兴的分子靶向治疗,对CML治疗方法发展概况辩证性、系统性地分析,指导临床选择合适的治疗方法,以争取达到最佳治疗效果。     

Fission and confusion.

Catholic opponents of abortion and embryonic stem cell research usually base their position on a hylomorphic account of ensoulment at fertilization. They maintain that we each started out as one-cell ensouled organisms. Critics of this position argue that it is plagued by a number of intractable problems due to fission (twinning) and fusion. We're unconvinced that such objections to early ensoulment provide any reason to doubt the coherence of the hylomorphic account. However, we do maintain that a defense of ensoulment at fertilization must deny that we're essentially organisms.     

Modern medicine and biotechnology: an ethical conflict of interest?

When confronting the issues related to developments in modern medicine and biotechnology, we must repeatedly ask ourselves anew what can and cannot be justified in an ethical sense. For radically new ethical questions seem to arise through innovative techniques such as stem cell research or preimplantation diagnosis — and with them new areas of conflicting interests. If one scrutinizes the previous positions related to this subject, it becomes conspicuous that a multitude of questions has quickly piled up — however, (as in the case of Germany) comprehensive and differentiated views have mostly been lacking. An earlier version of this paper was presented at an International Conference on “Conflict of Interest and its Significance in Science and Medicine” held in Warsaw, Poland on 5–6 April, 2002.
