Military medicine has to restructure itself to meet military needs and e-Science patterns of the information age.This restructuration is known asinformationization of military medicine ( IMM).IMM is a process of vision refresh-ing into information thinking, mission expansion to the information field and paradigm shift to normal forms of information. The result is the emergence of military med-information technologies, military med-information research fields, and military med-informatics disciplines.

Objective To explore an ideal surgical treatment for cervical sear eontraeture. Methods From January, 2005 to December, 2008, 11 eases of cervical sear contraeture (Ⅱ-Ⅲ) were treated with the expanded flaps based on the cervical cutaneous branch of transverse cervical artery. At the first step, one or two soft tissue expanders were implanted beneath the skin at the clavicular-pectoral region. At the second step, after fully expanding, an expanded clavicular-pectoral flap that based on the cervical cutaneous branch of transverse cervical artery was designed and raised completely according to cervical cutaneous defect. And then, the flap was transferred to reconstruct the defect in cervix. The donor area was closed directly or covered with graft. Results The 11 cases were performed with unilateral flaps based on the cervical cutaneous branch of transverse cervical artery. No necrosis occurred. And the cervical contour and function have been mended. All of them had been followed up for 6-18 months with satisfactory results. Conclusions This procedure can be very useful for the plastic and reconstruction surgeons who are confronted with a difficult case of cervical scar contracture. By this means, a lot of materials of reparation with similar color, and texture can be obtained. And this method is simple, safe, and effective.

Objective To explore an effective treatment for lactation complications after augmenta-tion mammoplasty with polyacrylamide hydrogel (PAHG). Methods 13 cases with lactation complica-tions after augmentation mammoplasty with polyacrylamide hydrogel (PAHG) were treated with taking out PAHG and the pathological tissue through the periareolar incision, using continual drainage and medi-cation that can choke back hypergalactia. Results All cases were cured and followed up for 3 months to 4 years with satisfactory results. Conclusion This method for the treatment of lactation complications after augmentation mammoplasty with PAHG is effective, safe and simple.

Objective To explore the effects of Medpor in surgical treatment of craniofacial de-pressed deformities. Methods Combining with other surgical methods, 37 patients with craniofacial de-pressed deformities were treated with Medpor. Of them, 29 cases of craniofacial depression and defects subjected to trauma, 6 cases were progressive facial hemiatrophy and 2 case were angle of mandible de-formity. All were followed up from three months to four year. Results Facial configurations and func-tions of all the 37 cases were greatly improved after the treatment, without any complication of infection or rejection;patients were all very satisfactory or relatively satisfied with the results. Conclusion Med-por is an ideal implant material to correct the deformity of earaniofacial, and combining with others methods, the treatment of earaniofacial deformity can obtain good results.

Objective To explore the clinical effect of transplantation of autologous fat with stromal vascular fraction for breast augmentation.Methods From September 2012 to March 2014,15 people accepted breast augmentation by transplanting autologous fat with SVF under local anaesthesia.Three-dimensional computer tomography reconstruction (3D-CT reconstruction) was applied preoperatively and postoperatively,the data of the thickness of breast's subcutaneous tissue was compared to observe the breast contour improvement.Results Autologous fat was injected 2 times in 3 cases,and the rest were 1 time.6 months after operation,13 cases were satisfied with the results,and 2 cases were quite satisfied.3D-CT reconstruction was performed before operation and 6 months after operation;statistics showed that before operation the thickness of breast subcutaneous tissue of the right side was (11±4) mm,the left side was (11±6) mm;6 months after operation the right side was (14±3) mm,the left side was (16±3) mm (P＞0.05).The breast was soft,no major complication such as nodules,cysts or calcification were seen.Conclusions The transplantation of SVF with autologous fat is a safe,effective procedure for breast augmentation.3D-CT reconstruction can show more details of breast structures,which is a more effective method to guide and evaluate the lipotrans plantation.
