Objective To repair and reconstruct severe burn wounds on face,hands and joints with the principles and techniques of plastic and aesthetic surgery.Methods Twenty three burn victims in a single batch were transferred from a remote area to our Burns Institute on post burn day 2,June 28,2006.All the patients were males aged from 17 to 46 years,with a mean of 24.4?6.3 years,the mean total burn area was 15.7%?13.9% TBSA(ranged from 6% to 75%),with moderate to severe inhalation injury,and fourteen of them had received tracheostomy.The burn areas on face ranged from 0.5% to 3% TBSA,and all of them were deep second or third degree burn.The burn areas on hands ranged from 1% to 4% TBSA of deep second or third degree.On post burn day 3,the patients received escharectomy or tangential excision of eschar on hands followed by split thickness skin grafting with the principles and techniques of plastic and aesthetic surgery.During post burn week 2 to 3,the eschar on the faces were peeled off,followed by split-thickness skin grafting according to the principles and techniques of plastic and aesthetic surgery.Results All the wounds on the face and joints were repaired successfully,the configuration and functions were satisfactory.Conclusion It is feasible to repair the burn wounds on face and joints with the principles and techniques of plastic and aesthetic surgery for the burn patients of mass fire catastrophe.

Objective To explore the efficacy of prefabricated expanded cervico-scapulo-dorsal reverse axial flap combined with cervico-thoracic skin flap to repair cicatricial contracture of lateral neck. Methods Ten patients with cicatricial contracture of lateral neck were repaired by prefabricated expanded cervico-scapulo-dorsal reverse axial flap combined with cervico-thoracic skin flap. The flaps were transferred to repair the wound caused by excision of the scar on the lateral side of the neck. Results All the twenty skin flaps survived in first intention. Both the configuration and function were satisfactory after 6 to 18-month follow-up. Conclusion Prefabricated expanded cervico-scapulo-dorsal reverse axial flap combined with cervico-thoracic skin flap is an ideal method to repair the cicatricial contracture of lateral neck.

Tissue-engineered skin plays an important role in clinical applications,and even the rapid development of science and technology promotes the research about it.Choosing an appropriate animal model for wound repair is the prerequisite for the objective evaluation of the object of study.In this paper,the research progress of animal models of wound repair was introduced from several aspects,such as selection of experimental animals,making of wound models,skin-related cells and materials,wound healing evaluation indexes,etc.,hoping to provide reference for later research work.

Objective To explore the application range of expand er s and its clinical efficacy in repair and reconstruction after burn. Methods Two hundred and eighty-six expanders were implanted in 80 burned patients. Volume of the smallest expander was 80cc, and that of the bi ggest one was 800cc. The expansive time ranged from 3 weeks to 2 months. In the second operation, expansive flaps were created and used in the de fected lesion where the scar was removed. Results 7 5 patients were followed up for at least one year with satisfactory results and only 3 patients showed complications that expanders exposed during expan sion. Conclusion Reasonable application of expanders coul d get satisfactory results in repair and reconstruction of severe scar, especia lly for scar at extremities and special sites after burn.

Objective To construct recombinant adenovirus vector carrying vascular endothelial growth factor 165(Ad-VEGF165),amplify the adenovirus vector in 293T cells,transfect Ad-VEGF165 into the bone marrow stromal cells(bMSCs) of Wistar rats,and then to assay the expression of VEGF165.Methods VEGF165 obtained by PCR was digested and inserted into adenovirus shuttle plasmid pAdTrack-CMV to generate recombinant plasmid pAdTrack-VEGF165,and then the Pme I-linearized plasmid pAdTrack-VEGF165 was electroporated into E.coli BJ5183 cells that had been electroporated adenovirus backbone plasmid pAdEasy-1.The identified recombinant plasmid pAdEasy-VEGF165 DNA was digested with Pac I and transfected into 293T cells to package adenovirus,followed by identification of the recombinant adenovirus by means of observation of the enhanced green fluorescence protein(EGFP) expression under fluorescent microscope.After amplified in 293T cells,the obtained adenovirus were transfected into 293T cells again,and EGFP expression was detected.Ad-VEGF165 transfected bMSCs were cultured in vitro.The expression of VEGF165 in bMSCs after transfection was determined by observing the expression of EGFP and detected by RT-PCR.ELISA method was applied to assay the secretion of VEGF165.Results Recombinant adenoviral VEGF165 was constructed successfully,which was confirmed by restriction enzyme digestion,gene sequencing and EGFP expression.EGFP expression could be observed under fluorescent microscope,and the expression of VEGF165 was confirmed by RT-PCR.ELISA analysis showed the quantity of expression of VEGF165 in transfection group was higher than that in control group(P

Objective To explore a method of large cranial bone defect reconstructed by titanium implant with computer aided design(CAD)/computer aided manufacture(CAM)technique.Methods From April 2006 to June 2008,7 cases of cranial bone defect due to tumor and trauma were admitted.The data of skull bone defects were obtained by CT.The resin model was designed and manufactured with rapid prototyping technique.Results The CT data could be used by image software directly.The resin model was manufactured accurately by RP technique.The titanium implant design could be completed by CAD/CAM.7 patients achieved one stage healing.After a follow-up of 6 months to 1 year,cranial bone defect was reconstructed satisfactorily.Conclusion Individual design and repair of large cranial bone defect with CAD/CAM technique is worth extending application clinically.It is a quite ideal and very simple method for the surgical treatment of the cranial bone defect.

Objective To explore a method for repairing the appearance and function of the cheek aesthetic unit.Methods A single volume of 100 ml to 150 ml of tissue expander was implanted at the lower edge of the injury area on the cheek.The first injection was performed 5 days after the operation and twice a week after the injection.It took an average of about 4 months to complete the expansion,with 3-5 times over expanded.The lesions were resurfaced with the expanded flaps,and long term follow-up was observed for flap survival.Results 17 cases of cheek lesions had been successfully reconstructed,with the color,texture of the expanded flaps well matched to the surrounding skin after 3-12 months follow-up.The facial expression functions and configurations were satisfied.Conclusions Excessive expansion of the prefabricated skin flap of the jaw and neck can repair the cheek aesthetic unit successfully,which is a practical method and meets the needs of aesthetic unit repair.
