It is expected that by 2050 the population over 65 in China will reach 400 million [1]. A recent epidemiological study in China has demonstrated that 75.8% of residents over 60 years old suffer from at least one chronic disease [2]. According to a report from China Centers for Disease Control and Prevention in 2020, the mortality rates (1/100000) of chronic diseases aged 45-60 and over 60 were 366.88, and 3504.22 respectively [3]. With the acceleration of the aging process, aging-related chronic diseases have become the top priority of disease health management.
