[Biomechanical study on the treatment of intertrochanteric fracture of A3.3 type with medial sustainable nail and proximal femoral anti-rotation nail].

Objective: A3 intertrochanteric fracture is an extremely unstable fracture, which is often treated with intramedullary nail, but the implant failure is common due to the posterior medial fragment cannot be reconstructed. A new medial sustainable nail (MSN-Ⅱ) which can reconstruct the femoral medial support by sustainable screw was introduced in this study. The mechanical effect was verified by biomechanical experiment.

A preclinical method for evaluating the kinematics of knee prostheses.

The primary intent of anatomical knee implants is to replicate the motions of a normal knee joint. In developing such designs, a preclinical evaluation of kinematic behavior is needed. This study introduces an in vitro testing method for recording movements of the knee joint.

[Study on purification technology of patchouly oil with molecular distillation].

Objective: To establish an advanced purification techniques of the essential oils obtained from Pogostemon cablin.

Method: Molecular distillation (MD) was applied.

Result: Four distillates were obtained, chemical constituents of which were analyzed with GC-MS.
