The bone mineral density (BMD) of ulnar and radial bone, osteocalcin (BGP), parathyroid hormone(PTH), calcitonin(CT) and pulmonary function parameters were measured in both groups.

• 测定了患者及正常人的尺、桡骨平均骨密度（bonemineraldensity，BMD）、骨钙素（osteocalcin，BGP）、甲状旁腺激素（parathyroidhormone，PTH）、降钙素（calcitonin，CT）及肺功能、血气等。
