ABSTRACT
Three-parent test tube baby technology is important to solve the mitochondrial genetic disease.Once available,it raises greatly ethical controversy such as breaking traditional family values,hitting the religious belief,existing unknown risks,correctly handling the failed embryo,as well as the influence on the social status of the babies.Regarding these controversy,we can discuss it from several aspects.Because the development of ethics is behind the progress of science and technology,we should affirm the value of three-parent test tube baby technology and balance the development of science and technology with respecting the religious beliefs.Strict supervision system and standard application system reflect our respect for life.Incomprehension to the unknown things should become the motivation of our inquiry.We should face up to our fear of three-parent test tube baby technology,and thus to strengthen research and deepen understanding.Based on the above argument,this paper puts forward the ethical principles that should be followed in the development of three-parent test tube baby technology,namely respect,benefit,no harm and justice.
ABSTRACT
Since CRISPR/Cas9 has been discovered,it opens a new era for gene therapy with its low cast,high efficiency,short cycle,easy operation and other characteristics.In 2015,Huang Junjiu had used the technique to nodify human embryonic cell for the first time,leading to widespread attention at home and abroad.For nearly 50 years,ethical discussion of gene therapy has never stopped.Through reviewing the development of gene therapy,this paper analyzed several key issues of ethical controversy in gene therapy,such as safety,effectiveness,justice,right,interest orientation and so on,and put forward that gene therapy and ethics are not two opposite sides and cannot be treated separately,the development of gene therapy should follow certain ethical norms and technical norms and it should use the bioethical principles to direct gene therapy.
