1.Methods: Fifteen cases of cervicothoracic fracture were performed on anterior subtotal vertebraectomy at C 7,T 1,C 6,7 or C 7T 1 segment, bone graft and Orion anterior cervical locking plate fixation in cervicothoracic spine.
2.Methods The clinical characteristics of 26 cases of cervicothoracic spine and spinal cord trauma were analyzed, which were performed with anterior subtotal vertebraectomy at C 7,T 1, C 6~7 or C 7~T 1 segment, bone graft and Orion anterior cervical locking plate fixation in cervicothoracic spine.
7.Using Sm 3+ as an example, the extraction spectrophotometric characteristic of the system of Ln 3+ 5,7 dichloro 8 hydroxyquinoline(DCO) safranine T(SFT) has been investigated.
