National Health Commission (NHC) Key Laboratory of chronobiology (Sichuan University) was established with the consent of the Ministry of Health in August 2005. It was evaluated and passed the assessment by the experts of the Ministry of Health in 2005. It is one of the earliest research institutions in China to carry out chronobiology research. The laboratory passed the assessment again in 2011 and 2016, and was rated as merit（the evaluation criteria are divided into unqualified, qualified, merit, distinction）. In 2018, according to the requirements of the National Health and Family Planning Commission for the development of committee level key scientific research bases for applied basic research, the research focus of Key Laboratories began to shift from basic mechanism research to basic research closely combined with clinical research. In 2019, according to the relevant work arrangements and requirements of the NHC, our laboratory passed the re-identification of NHC key research base, and officially changed its name from the former Key Laboratory of the Ministry of Health to NHC Key Laboratory of chronobiology (Sichuan University).

The current director of the key laboratory is Professor Liu Hanmin. Our laboratory is a systematic research platform composed of basic medicine and clinical medicine. The laboratory construction ob-x-jective is to establish a domestic first-class and internationally renowned chronobiology laboratory. The laboratory carries out basic medicine and clinical medicine research; attaches importance to the role of translational medicine as a link, and is committed to solving chrono medicine-clinical problems. It aims to achieve a research system with solid foundation, efficient conversion, reliable application, and distinctive characteristics; and builds an innovation platform and talent training platform to serve people's health.
