[Endoscope-assisted repair of pediatric blowout fractures of orbital floor with autologous bone fragment].

Objective: To explore the clinical efficacy of endoscopic repairing pediatric blowout fracture of orbital floor with autologous bone fragment.

Methods: A total of 12 cases with blowout fractures of orbital floor between March 2010 and June 2012 at Third Hospital of HeBei Medical University were reviewed. They underwent nasal endoscopic reconstruction of autologous bone fragment in situ.

[A clinical study on reparation of orbital blowout fracture by bridge hydroxylapatite artificial bone].

Objective: To explore a minimally invasive technique with hydroxylapatite artificial bone to repair the orbital blowout fracture.

Methods: Twenty-one cases of orbital blowout fracture from March 2008 to April 2010 were enrolled. And the fractures were repaired with a bridge of hydroxylapatite artificial bone under a nasal endoscope.

A preliminary study of mesenchymal stem cell-like cells derived from murine corneal stroma.

Background: Mesenchymal stem cells can be isolated from various tissues besides bone marrow and can differentiate into cells of three germ layers. Recent studies indicate that some cells in corneal stroma express stem cell markers and can also differentiate into chondrocytes and neurocytes. This study was carried out to investigate whether mesenchymal stem cells reside in the murine corneal stroma.
