[The effects of the autologous venous external stents on intimal hyperplasia of the vein grafts in rabbits].

Objective: To assess the effect of the autologous venous external stents on intimal hyperplasia of the vein grafts in rabbits.

Methods: Thirty-six male New Zealand white rabbits, aged 5 months and weighing 2.8 to 3.

[Biomechanical study on the calcaneal fracture fixed by the self-designed calcaneal anatomical plate and pre-cut gudgeon].

Objective: To study the biomechanical properties of self-designed calcaneal anatomical plate and pre-cut gudgeon system and its efficacy for calcaneal fracture fixation.

Methods: Sixteen fresh foot specimens were randomly divided into experimental group and the control group. Axial compressive load were applied to all specimens in order to create a calcaneal fracture model, and the maximum load and the maximum arch displacement of experimental group were recorded.
