This study is a single-center prospective observational study. It aims to utilize a series of physiological and medical instruments in conjunction with internationally recognized physiological and psychological questionnaires to monitor the dynamic shifts in the acclimatization ability of doctors from Peking Union Medical College Hospital. The monitoring will occur at seven distinct time points: pre-departure from Beijing, 1-7 days post-arrival at the Tibetan plateau during the acute phase of plateau hypoxic stress, and during the chronic phase of plateau hypoxic stress at 2 weeks, 3 months, 6 months, 12 months of residency in Tibet, and post-return to Beijing. Concurrently, a spectrum of omics analyses will be conducted, including comprehensive genomic, proteomic, and metabolomic assessments of blood leukocytes, fecal, and oral samples.
