人类干细胞之伦理原则与监管政策(上)

本文分两大部分.第一部分从干细胞的功能、来源与社会争议性3种角度划分了人类干细胞的种类,并讨论与人类干细胞研究及临床应用相关的9条伦理原则,特别强调了西方国家对胚胎捐赠在知情同意方面的伦理要求.第二部分讨论了制定监管人类干细胞研究的3个原则,并简单地介绍了在英美各国监管的情况,其中较详细地评论了英国的种种立法过程、设立的法定机构和执行的种种政策与机制,作为在我国讨论类似政策参考之用.     

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。     

重视干细胞研究中的伦理问题

黄禹锡的“卵子风波”反映了干细胞研究领域中伦理规范的缺位。分析了针对干细胞研究的种种伦理争论,并且指出,由于与人类的尊严和幸福密切相关,生物医学领域的研究不能回避伦理问题,相关的伦理研究必须与科学研究同步进行。

日本的人类胚胎干细胞研究

干细胞研究的进展体现了人类智慧的一个胜利,但同时也对人类的生命提出了极大的挑战,因为这意味着无论是作为一个整体的社会还是个体,都将面临严肃的伦理、法律及社会问题.通过成人干细胞临床研究原则草案论纲,讨论日本的人类胚胎干细胞研究.     

人类干细胞研究及若干伦理问题

人类干细胞研究是生命科学一大热点,围绕干细胞研究有许多伦理问题争论,根据国际生命伦理准则,并结合我国的实际情况,论述干细胞研究的有关伦理问题,并对我国制订干细胞研究伦理指导大纲提出了建议。     

人类干细胞之伦理原则与监管政策(下)

4监管人类干细胞研究政策与组织 由于人类干细胞的研究牵涉大量上述的伦理道德问题,大部分的西方国家都纷纷通过立法强制监管这方面的研究,并且设立相关的机关执行一套详尽与完善的监管程序.甚至看来政策有点混乱的美国,因为政府的态度太过保守,以至国会与参议院无法达成共识,通过有关法案,但事实上今天美国干细胞的研究人员,尽管他们不能获得联邦政府在经费上的资助,但他们的研究活动却处处受到联邦政府不同的部门的监管.     

人类胚胎干细胞研究的伦理观分析

人类胚胎干细胞是存在于人类早期胚胎中,具有发育多能性的细胞类型.人类胚胎干细胞研究能够帮助科学家了解并治疗帕金森氏症、脊髓损伤等重大疾病.然而,由于提取人类胚胎干细胞的过程中需要摧毁胚胎,该研究从一开始就饱受伦理争议.本文将首先理清人类胚胎干细胞研究伦理争议的本质,对各种观点进行详细解析,进而判断代表我国民众的伦理观念,为构建适合我国人类胚胎干细胞研究的法律规制体系提供理论基础.

Religion and the body in medical research

Religious discussion of human organs and tissues has concentrated largely on donation for therapeutic purposes. The retrieval and use of human tissue samples in diagnostic, research, and education contexts have, by contrast, received very little direct theological attention. Initially undertaken at the behest of the National Bioethics Advisory Commission, this essay seeks to explore the theological and religious questions embedded in nontherapeutic use of human tissue. It finds that the "donation paradigm" typically invoked in religious discourse to justify uses of the body for therapeutic reasons is inadequate in the context of nontherapeutic research, while the "resource paradigm" implicit in scientific discourse presumes a reductionist account of the body that runs contrary to important religious values about embodiment. The essay proposes a "contribution paradigm" that provides a religious perspective within which research on human tissue can be both justified and limited.     

Human embryonic stem cell research: an intercultural perspective

In 1998, researchers discovered that embryonic stem cells could be derived from early human embryos. This discovery has raised a series of ethical and public-policy questions that are now being confronted by multiple international organizations, nations, cultures, and religious traditions. This essay surveys policies for human embryonic stem cell research in four regions of the world, reports on the recent debate at the United Nations about one type of such research, and reviews the positions that various religious traditions have adopted regarding this novel type of research. In several instances the religious traditions seem to have influenced the public-policy debates.     

The Therapeutic Promise of Pluripotency and its Political use in the Italian Stem Cell Debate

Stem cell research is considered one of the most promising branches of contemporary biomedicine. The capacity to develop into almost any cell type of the mature organism—pluripotency—is associated with human embryonic stem cells (hESCs) and is regarded as having great therapeutic potential. Harvesting stem cells destroys the human embryo, however; so research on embryonic stem cells has provoked controversies. In some countries such as Italy, the use of human embryos for research and therapeutic purposes is strictly forbidden. The Italian restrictive regulation has been explained by structural–cultural factors such as religion, but a better explanation lies in the policy dramaturgies deployed in the Italian debate. It was a struggle between two research trajectories—research on hESCs and on adult stem cells—for monopoly over the most credible therapeutic promise. Each was linked to different views of the Italian social order; each was epistemically legitimized by discourses on pluripotency and on the therapeutic potential of different stem cell types. Catholic actors articulated epistemic discourses on the therapeutic promises of different stem cell sources. The battle to define the social order—between a secular and a confessional view—became a struggle between two research trajectories for monopoly over the most credible therapeutic promise. The restrictive regulatory framework resulted from successfully transforming a policy dramaturgy into a new regulatory order. Thus structural–cultural variables such as religiosity matter only through the agency of institutional actors in local political cultures.     

Patently controversial: markets,morals, and the President's proposal for embryonic stem cell research

This essay considers the implications of President George W. Bush's proposal for human embryonic stem cell research. Through the perspective of patent law, privacy, and informed consent, we elucidate the ongoing controversy about the moral standing of human embryonic stem cells and their derivatives and consider how the inconsistencies in the president's proposal will affect clinical practice and research.     

伦理,胚胎和干细胞研究

道德是关于规则、直觉、理解和观点的一个复杂系统。而后者影响着我们相互间处理事务的方式。它们交叉地渗入我们的道德思考。这种思维与胚胎、干细胞的伦理密切相关,因为胚胎和干细胞涉及我们对与治疗和移植组织有关的人的生命及其启始问题。就像在许多对待生命及其可以阐释的研究方法方面,要有一个道德的思辩历程一样,解决这些问题,部分地需要讨论,部分地需要回答。只有在我们认定这种讨论能够融入应用干细胞治疗的胚胎及其类源和人体组织的使用中时,我们才会清楚,大多数人体不同部位的干细胞应用是经过了对人的生命启始、我们儿童、家庭进行了思考。     

Preembryo Personhood: An Assessment of the President’s Council Arguments

The President’s Council on Bioethics has addressed the moral status of human preembryos in its reports on stem cell research and human therapeutic cloning. Although the Council has been criticized for being hand-picked to favor the right-to-life viewpoint concerning human preembryos, it has embraced the idea that the right-to-life position should be defended in secular terms. This is an important feature of the Council’s work, and it demonstrates a recognition of the need for genuine engagement between opposing sides in the debate over stem cell research. To promote this engagement, the Council has stated in secular terms several arguments for the personhood of human preembryos. This essay presents and critiques those arguments, and it concludes that they are unsuccessful. If the best arguments in support of the personhood of human preembryos have been presented by the Council, then there are no reasonable secular arguments in support of that view.     

Hub‐and‐Spoke Student Blogging and Advantages for Classroom Discussion

This essay argues for a particular form of student blogging as a powerful tool for generating and sustaining student engagement and conversation. After a brief discussion of pedagogical principles, “hub‐and‐spoke” blogging is presented as a means to facilitate a more student and discussion‐centered classroom. Based upon recent research and the author's experience, blogging is shown to have a significant impact on both student and instructor preparation for class and to positively shape instructional time.     

关于干细胞研究的伊斯兰教观点

干细胞的来源主要有3个,分别是胚囊阶段的人胚胎细胞内物质,胎儿和成人细胞。从伊斯兰教观点来分析干细胞研究,干细胞研究具有巨大潜力使人们受益。但是,胚胎的道德地位是讨论的实质。特别指出仅为胚胎干细胞研究的目的而创造胚胎是不能被接受。
