血中25羟维生素D_3(25OHD_3)、免疫活性甲状旁腺激素(iPTH)、降钙素(CT)和甲状腺激素(T_3、T_4)直接与钙磷代谢和骨代谢相关,而上述激素浓度变化又与成年后与年龄相关的骨质丢失密切相关。本文以45例80～100岁的健康老人为对象,综合观察其血中25OHD_3、iPTH、CT、T_3和T_4浓度的变化,并特别以32例3～17岁儿童和青少年作为对照进行观察。
Blood 25 hydroxyvitamin D3 (25OHD3), immune active parathyroid hormone (iPTH), calcitonin (CT) and thyroid hormones (T_3, T_4) are directly related to calcium and phosphorus metabolism and bone metabolism, and the above hormone concentration changes It is closely related to age-related loss of bone mass. In this paper, 45 healthy elderly people aged 80-100 years old were selected as the objects, and the changes of 25OHD_3, iPTH, CT, T_3 and T_4 concentrations in the blood were observed. 32 children and adolescents aged 3 to 17 years were taken as control.
