生长、发育、衰老、死亡是一切生物,包括人类在内的生命过程和自然规律。衰老为生物生命周期的后期阶段,随着年龄增长,机体组织器官的形态、结构和生理功能等方面都会出现一系列特异的慢性、进行性、退行性变化,这些变化导致机体适应能力和储备能力逐渐下降,这个过程不断发生、发展称之为衰老,又叫老化。认识衰老,延缓衰老,延长寿命,提高生活质量,一直是世界生命科学研究的主要内容。
Growth, development, aging, death are the life processes and laws of nature of all living things, including humans. Aging is the later stage of the biological life cycle, with age, there will be a series of specific chronic, progressive and degenerative changes in the morphology, structure and physiological functions of the tissues and organs of the body. These changes lead to the body’s adaptability and reserve capacity Gradually decline, this process continues to occur, the development known as aging, also known as aging. Recognizing aging, delaying aging, prolonging life expectancy and improving quality of life have always been the major components of life science research in the world.
