Screw placement of pedicle of vertebral arch--pay great attention to segmental differences of the pedicle.
To investigate appropriate ways for screw placement of pedicle of vertebral arch in the horizontal plane. ⋯ The segmental difference method is proved to have the anatomic safety and screw biomechanical stability. It is appropriate to choose different diametral screws, different drilling points and directions according to different segments of the vertebra.

Changes of bcl-x(L) and bax mRNA expression following traumatic brain injury in rats.
To investigate the changes of bcl-2 gene family and the molecular mechanism of neuronal apoptosis following traumatic brain injury (TBI) in rats. ⋯ Decreased expression of bcl-x(L) mRNA and increased expression of bax mRNA coincides with apoptosis following brain injury. The bcl-2 gene family is involved in neuronal apoptosis after TBI, and the changes of mRNA expression of the family members lead the neuronal cells to apoptosis.
