摘要
In Department of Space Radiobiology,the mechanisms of senescence and immune responses of cancer and normal cells induced by ionizing radiation have been investigated in vivo and in vitro during the past year.Meanwhile,along with the growing number of flights in space,astronauts will be exposed to harsh space environments such as microgravity and heavy ions.Space environments can cause serious bone loss and lead to the osteopenia of astronauts at vertebra,pelvis and femur,which is a major challenge in long-term spaceflight.The main achievements on these research fields in the year of 2018 can been summarized as followings。
