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.
Background: Prostaglandin E2 (PGE(2)) is a key modulator of dendritic cells (DCs) function, and cornea-derived transforming growth factor beta 2 (TGF-β(2)) promotes the generation of phenotypically and functionally immature DCs. Therefore, this study was carried out to investigate whether PGE(2) is involved in the suppressive effect on DCs maturation mediated by corneal stroma cells (CSCs) and whether PGE(2) and TGF-β(2) have additive effects in this immunosuppressive mechanism.
Methods: Bone marrow-derived DCs (BM-DCs), splenic T cells and CSCs culture supernatant were obtained from mice via various protocols.
Purpose: The aqueous humor (AH) contains numerous immunosuppressive molecules that contribute to the ocular immune privilege. Here, we mimic an inflammatory environment to analyze the inhibitory effects of the AH on lipopolysaccharide (LPS)-induced maturation of dendritic cells (DC).
Methods: Different concentrations of AH were added to dendritic cell cultures together with LPS.
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.
