Leukopenia from exposure to ionizing radiation has been reported. Due to their radiosensitivity, leukocytes are a biological model to analyze cell damage. Therefore, cell viability, DNA damage, and Hsp70 and p53 expression in human leukocytes exposed to low-dose gamma radiation fields from a <sup>137</sup>Cs source were evaluated. A decrease in cell viability, DNA damage and an increase in the expression of Hsp70 and p53 proportional to the radiation dose received was found, which was 0.2, 0.4, 0.6, 0.8 and 1.0 mGy.展开更多

By constructing rat atherosclerosis model, a variety of experimental techniques (such as immunohistochemistry staining, real-time fluorescence quantitative PCR, protein blotting, enzyme-linked immunosorbent assay, etc.) and instruments (such as color Doppler ultrasound diagnostic instrument) were used to systematically and comprehensively analyze the expression status, regulatory mechanism and relationship between P53 and P21 and disease progression in the two groups. The research results are expected to provide novel and valuable targets and strategies for the diagnosis and treatment of atherosclerosis.展开更多
