To study the effects of kneepad on expression of Bcl-2 and p53 mRNA of chondrocyte in white rabbits with knee osteoarthritis, so as to explore and treatment mechanism of OA kneepad on apoptosis of chondrocytes of rabbits with knee osteoarthritis in molecular degree. ⋯ OA-kneepad can up-regulate the mRNA expression of Bcl-2 as well as down-regulate the mRNA expression of p53, thereby to inhibit the apoptosis of cartilage cells and delay the degeneration of articular cartilage changes.

To explore pedicle screw implantation for fracture-dislocation injuries at cervicothoracic junction (C6-T2). ⋯ Implantation of pedicle screws at cervicothoracic junction can be safe and reliable if the urgeonis familiar with the local anatomy of cervicothoracic spine, and the technique for implantation of the screws. Related radiological parameters should be measured for each subject before the operation in attempt to get a therapy individually.

Comparative Study
[Comparison of proximal femoral nail and dynamic hip screw for treating intertrochanteric fractures].
To discuss characters of proximal femoral nail and dynamic hip screw for treating type A1, A2, A3 of intertrochanteric fractures. ⋯ The therapeutic effect of DHS and PEN was primitively same in treating type A1 of intertrochanteric fracture. Operative injuries of PFN were less than that of DHS and anti-tonia was more stronger which is more suitable for type A2 and A3 of intertrochateric fractures.

Clinical Trial
[Selective treatment of thoracolumbar fracture with posterior monosegmental pedicle screw fixation].
To explore the clinical effects of posterior monosegmental pedicle screw fixation in selective treatment of thoracolumbar vertebral fractures. ⋯ As indication is correctly choosed, posterior monosegmental pedicle screw fixation can be applied to treat thoracolumbar vertebral fractures.
