Comparative Study[Development of static three dimensional screw-plate system and the biomechanic features thereof, a comparative study].
To develop a new internal fixation device and the matching tools for subtrochanteric fracture, investigate the biomechanical features thereof, and compare its effects with those of other instruments. ⋯ More capable of resisting bending than DHS and less capable of resisting axial compression, STDSP is an excellent internal fixator with good biomechanical feature in treating subtrochanteric femoral fracture.

Randomized Controlled Trial[Epidural analgesia in latent phase of labor: effects on length of labor and mode of delivery].
To compare the outcome of ropivacaine plus sufentanil for patient-controlled epidural analgesia between nulliparous women presenting in latent and active labor. ⋯ Compared with epidural analgesia in active phase of labor, early administration of epidural analgesia in latent phase did not prolong labor, however, the caesarean section rate was increased and instrumental delivery rate was decreased.

[Aortic arch operation under deep hypothermic circulatory arrest].
To summarize the surgical experience of aortic arch operation under deep hypothermic circulatory arrest. ⋯ Aortic arch operation includes partial aortic arch replacement, total arch replacement, and total arch replacement with elephant trunk technique. The operation procedure is selected according to the primary lesion and how aortic arch has been affected. Deep hypothermic circulatory arrest with selective cerebral perfusion facilitates complicated aortic arch operation, resulting in a reduction of mortality and morbidity for arch aneurysms or dissection.
