[The significance of ultrasound and mammography in the diagnosis of fat necrosis after fat transplantation in breasts].

Objective: To investigate the significance and images characters of ultrasound and mammography in the diagnosis of fat necrosis after fat transplantation in breasts(FTB).

Methods: From June 2005 to June 2012, 13 cases with 96 fat necrosis lumps after FTB, were retrospectively reviewed. The pre-operative images of ultrasound and mammography, as well as the post-operative histologic results were collected.

Cobalt chloride improves angiogenic potential of CD133+ cells.

Umbilical cord blood-derived CD133+ cells exhibit the ability to differentiate into endothelial cells and induce new blood vessel growth. Hypoxia-inducible factor-1 (HIF-1), a regulator of hypoxia or the hypoxia-mimetic agent response, actives the SDF-1/CXCR4 signaling pathway and thus plays an important role in angiogenesis in-vivo. In this study we aim to investigate whether CD133+ cells enhance angiogenic ability through hypoxia or CoCl2 in vitro.

Transplanted endothelial progenitor cells increase neo-vascularisation of rat pre-fabricated flaps.

Background: Flap pre-fabrication is dependent on the eventual re-vascularisation of the implanted vascular carrier and the presence of a desirable, donor-skin site. However, insufficient neo-vascularisation and subsequent necrosis is an obstacle for this technique. A recent discovery demonstrated that endothelial progenitor cells (EPCs) augment post-natal neo-vascularisation in ischaemic tissues.

An integrated fat grafting technique for cosmetic facial contouring.

Background: Although several methods of fat grafting have been reported, there is no agreement regarding which technique should be used for autologous fat grafting and the final outcome after fat grafting often depends on the technique used by a surgeon. In this report we present an integrated fat grafting technique developed over the years for cosmetic facial contouring.

Method: Fat grafts were harvested under low pressure with syringes, processed with low speed centrifugation, and then injected into the affected areas of the face with low volume for each pass via multi-tunnels, multi-planes, and multi-points.

Autologous fat grafting to the breast for cosmetic enhancement: experience in 66 patients with long-term follow up.

Background: Autologous fat grafting to the breast for cosmetic enhancement remains controversial because the efficacy and fate of fat grafting to the breast are primarily unknown. In this report, we present our retrospective study in 66 patients who underwent autologous fat grafting to the breast for various cosmetic reasons and who were followed with sonography, mammography, or magnetic resonance imaging (MRI).

Methods: Sixty-six patients who desired cosmetic enhancement of the breast for various reasons underwent autologous fat transplantation between August 2000 and March 2005 in our institution.

Correction of hemifacial atrophy with autologous fat transplantation.

Background: Autologous fat transplantation has frequently been used by many surgeons for facial recontouring in esthetic patients, with good long-term results. However, this technique has not been used primarily in treating patients with hemifacial atrophy, and its efficacy and long-term outcome remain unknown.

Methods: In a 7-year period, 31 patients with hemifacial atrophy were treated with autologous fat transplantation in our institution.
