Experimentation research of serum thymidine kinase 1 in young and middle-aged people in high humidity and high altitude area

Objective To investigate the difference of serum thymidine kinase 1 (TK1) levels of young and middle-aged people in high humidity and high altitude area. Methods Serum level of TK1 was measured with the enhanced chemiluminescence method in 128 native young and middle-aged people. Results Serum TK1 was (1.784 2 + or - 0.127 9) pmol/L in the control group and (1.385 0 + or - 0.078 5) pmol/L in the test group, the difference between them had statistical significance (P
