Ethical review means that any scientific research involving human biology must pass the ethical review of specialized institutions. Only in this way can we ensure that the research process and results conform to human ethics and public morality, resolutely put an end to research behaviors that violate human ethics, safeguard human life and health, and safeguard human dignity. Ethical review is an indispensable part of research-oriented papers, which directly determines the "fate" of submission in the first trial and is the "passport" for articles to enter the trial smoothly.
