A synthetic oxygen carrier-olfactory ensheathing cell composition system for the promotion of sciatic nerve regeneration.

The treatment of lengthy peripheral nerve defects is challenging in the field of the regenerative medicine. Thus far, many nerve scaffolds with seeded cells have been developed, which hold great potential to replace nerve autograft in bridging lengthy nerve defects by providing guiding and bioactive cues. However, low oxygen status has been found within nerve scaffolds after their implantation in vivo, which has been shown to result in death or loss of function of supportive cells, and significantly limit nerve regeneration and functional recovery after nerve injury.

[Effectiveness of combined treatment of lumbar spondylolisthesis with MED, Quadrant, and Sextant-R systems].

Objective: To analyze the effectiveness of combined treatment of lumbar spondylolisthesis with MED, Quadrant, and Sextant-R systems.

Methods: Between August 2006 and June 2011, 35 patients with lumbar spondylolisthesis were treated, including 11 cases of isthmic spondylolisthesis and 24 cases of degenerative spondylolisthesis. There were 25 males and 10 females, with a mean age of 55 years (range, 33-71 years).

[Computer-aided precise resection of pelvic tumor and function reconstruction].

Objective: To investigate the value of computer-aided design (CAD) in defining the resection boundary, reconstructing the pelvis and hip in patients with pelvis tumors.

Methods: Between November 2006 and April 2009, 5 cases of pelvis tumors were treated surgically using CAD technology. There were 3 males and 2 females with an average age of 36.
