    This paper investigates the efficiency of application of medical ethics principles in the practice of artificial insemination by donors (AID) in China, in a culture characterised by traditional ethical values and disapproval of AID. The paper presents the ethical approach to AID treatment as established by the Reproduction and Genetics Hospital of CITIC-Xiangya (CITIC Hunan-Yale Approach) in the central southern area of China against the social ethical background of China and describes its general features. The CITIC-Xiangya Approach facilitates the implementation of ethical relations between clinicians and patients participating in AID treatment procedures in Hunan-Yale.

    Yousheng meaning eugenics or healthy-birth and youyu meaning good-upbringing are necessary requirements for the development of human beings and therefore of humankind generally. There are enormous ethical issues involved in eugenics. An important task or calling of contemporary bioethics and ethics of population is to discuss these issues in order for people, even people in different countries and cultures, to reach some basic consensus and have practical ethical guidance. Based on the practice of yousheng in contemporary China, this paper offers a Chinese perspective on ethical dimensions of eugenics. It will argue that individuals, as members of society, have a duty to provide society with healthy and normal children. Moreover, this paper examines the relationships between the aim and the means and conflicts between collective value and individual value, in yousheng.

    Preimplantation genetic diagnosis (PGD) is an exciting new approach for the prevention of transmission of genetic disorders between generations. The use of genetically screened, healthy embryos to establish a pregnancy avoids the need for termination of an affected pregnancy, a procedure which can be traumatic physically and emotionally for potential patients, and is sometimes not available when needed. PGD usually follows the processes of ovarian hyperstimulation and in vitro fertilization (IVF). After carrying out appropriate genetic tests, only normal embryos are transferred to the patient\'s uterus to achieve an unaffected pregnancy and the birth of a healthy infant.

    OBJECTIVE: The aim of the study was to assess whether preimplantation genetic diagnosis (PGD) was an acceptable alternative to prenatal diagnosis in couples at risk of giving birth to a child with alpha- or beta-thalassaemia in an Asian population.
    METHODS: An information leaflet was distributed to the women at risk. They were asked to complete a questionnaire after having an interview with a designated investigator.
    RESULTS: A total of 141 valid questionnaires were analysed; 82.3% of the women considered PGD either the same or better than conventional prenatal diagnosis. Women with an affected child or a subfertility problem were more willing to accept PGD and to undergo this procedure in their future pregnancies. Their main concern about PGD was damage to the embryo during the PGD procedure. The most important perceived advantage of PGD was avoidance of termination of an affected pregnancy.
    CONCLUSIONS: PGD is an acceptable alternative to conventional prenatal diagnosis in women at risk of giving birth to a child with alpha- or beta-thalassaemia in an Asian population. This is particularly true in women with a subfertility problem and in women who already have an affected child.

    To identify Chinese geneticists\' views of ethical issues in genetic testing and screening, a national survey was conducted. Of 402 Chinese geneticists asked to participate, 255 (63%) returned by mail anonymous questionnaires. The majority of respondents thought that genetic testing should be offered in the workplace for alpha-antitrypsin deficiency (95%) and the predisposition of executives to heart disease, cancer, and diabetes (94%); that genetic testing should be included in preemployment physical examinations (86%); that governments should require premarital carrier tests (86%), newborn screening for sickle cell (77%), and Duchenne muscular dystrophy (71%); and that children should be tested for genes for late-onset disorders such as Huntington disease (85%), susceptibility to cancers (85%), familial hypercholesterolemia (84%), alcoholism (69%), and Alzheimer disease (61%). Most believed that partners should know each other\'s genetic status before marriage (92%), that carriers of the same defective gene should not mate with each other (91%), and that women should have a prenatal diagnosis if medically indicated (91%). The majority said that in China decisions about family planning were shared by the couple (82%). More than half had views that, in China, there were no laws to prohibit disability discrimination (64%), particularly to protect people with adult polycystic kidney disease (57%), cystic fibrosis (56%), or genetic predisposition to other diseases (50%). To some extent, these results might provide a basis for a discussion of eugenics in China, particularly about China\'s Maternal and Infant Health Care Law (1994).

    对道德的态度,对来自中国30个省、自治区的402家遗传服务提供者进行了遗传研究和实践中的法律和社会问题调查。这是使用已在37个国家/地区发行的有关道德和遗传学的国际调查问卷的中文版本完成的。总之,255名研究参与者完成了问卷调查(63%)。大多数受访者(89%)表示,他们同意中国现行的有关遗传异常和非医学指征终止妊娠的法律法规,在考虑人口控制和计划生育的基础上。超过一半的受访者反对在没有X连锁疾病的情况下通过产前诊断进行性别选择。然而,他们中的大多数(86%)更喜欢指导咨询。超过一半的人会同意向有风险的亲属披露遗传信息,并允许第三方如执法机构,配偶/伴侣,血亲,涉及公共安全的雇主,生命和健康保险公司在未经同意的情况下访问存储的DNA。大多数人(73%-98%)还认为,被定罪或被指控犯罪的囚犯应该需要进行DNA指纹识别,武装部队成员和所有新生儿。虽然这些只是我们国际调查结果的第一部分,它们为在中国进行有关伦理学和遗传学的国际讨论提供了初步基础。
    Attitudes towards ethical, legal and social issues in genetic research and practice were investigated in 402 genetic services providers from 30 provinces and autonomous regions in China. This was done using a Chinese version of an international survey questionnaire on ethics and genetics that has been circulated in 37 nations. In all, 255 study participants completed questionnaires (63%). The majority of the respondents (89%) reported that they agreed with the current Chinese laws and regulations on termination of pregnancy for genetic abnormalities and non-medical indications, on the basis of considerations of population control and family planning. More than half the respondents opposed sex selection by prenatal diagnosis in the absence of an X-linked disorder. However, most of them (86%) would prefer directive counseling. More than half would agree to disclose genetic information to relatives at risk, and would permit third parties such as law enforcement agencies, spouse/partner, blood relatives, employers involving public safety, life and health insurers to access stored DNA without consent. The majority (73%-98%) also thought that DNA fingerprinting should be required for prisoners convicted of or charged with crimes, members of armed forces and all newborns. Although these are only the first part of the results of our international survey, they provide an initial basis for international discussion on ethics and genetics in China.
