Methods:Taking 156 sufferers of auriclar keloid at the orthopaedics department of the Southwest Hospital under the Third Military Medical University from June, 2008 to June, 2011 as the research subject, this research carried out retrospective analysis and summary of different surgical methods with the clinical data of subseque nt treatments, including medicament, radiotheropy, pressure, etc. Results:There was no auricular cartilage necrosis and deformation in the total of 156 cases. It was found that 134 cases were cured in a year of postoperative follow-up, getting the care rate to 85.9%. The treatment was effective on 20 cases, with the effective rate of 12.8%, while it was ineffective on 2 cases, with the ineffective rate being 1.3%. However, two cases showed tendency towards recurrence, which were treated effectively by non-surgical methods like local hormone injection. There was neither recurrence nor apparent hyperplasia of hypertrophic scars on the rest cases, with the auricle and the earlobe in good shape. Conclusion:By auricular keloid excision and stripping surgery, surgical suture tension was reduced. Glucocorticoid and radiotherapy were instantly applied to inhibit pyperplasia of cicatrical tissue. Subsequently, pressure, anti-scarring drugs and silicone membrane were adopted to ensure fine postoperative apperance and reduce recurrence. These methods were proved to be effectiveand they provided systematic and effective treatment for auricular keloid.展开更多

China has a vast territory frequently struck by natural disasters. However, the reality is not optimistic. Poor organization and management during the rescue actions, the lack of large-scale, systematic medical rescue equipment were all great barriers to the outcomes. Mobile hospitals are expected to provide better health care. We were inspired by the concept of mobile hospital. Chongqing Emergency Medical Center, has set up trauma care system since 1988, in which pre- hospital care, intensive care, and in-hospital treatment is fully integrated. As a major advantage, such a system provided assurance of＂golden hour＂ rescue treatment. Providing mobile intensive care and pre- hospital surgical service for severe trauma patients could reduce mortality significantly. Based on the civilian experiences in Chongqing Emergency Medical Center, the mobile emergency （surgical） hospital was developed. 2015 Production and hosting by Elsevier B.V. on behalf of Daping Hospital and the Research Institute of Surgery of the Third Military Medical University.展开更多

Methods： Altogether 45 rabbits were subjected to BSI by type II biological impact machine designed by the Third Military Medical University. The animals were divided into 4 experimental groups （n=10） and 1 control group （n=5） ac- cording to different magnitudes of impact pressure imposed on the occipital nodule： Group 1,500-520 kPa; Group 2, 520- 540 kPa; Group 3,540-560 kPa; Group 4, 560-580 kPa and Group 5, 0 kPa with 20 kPa increase in each grade. The im- pact depth was a constant 0.5 cm. After injury, the clinical symptoms and signs as well as pathological changes were observed. Results： Rabbits in Group 1 revealed mild physiologi- cal reaction of BSI. They had localized cerebral contusion with punctate hemorrhage and subarachnoid hemorrhage （SAH） was limited to the peripheral tissues at the impact area. In Group 2, obvious physiological reaction was observed. Local pathological lesions reached the superfi- cial layer of brainstem tissues; focal hemorrhage and girdle- shaped SAH in basilar pon were observed under microscope. In Group 3, BSI was more severe with a long respiratory depression. Pathological lesions reached the inner portionof brainstem with massive hemorrhage and the whole brainstem was wrapped by subarachnoid hematoma. In Group 4, most rabbits died due to severe BSI. Pathological lesions deepened to the central brainstem with wide patho- logical change, rapture of the medulla oblongata central canal. Group 5 was the control group, with normal brainstem structure and no lesion observed. Conclusion： This model successfully simulates differ- ent levels ofbrainstem mechanical injury and clearly shows the subsequent pathological changes following injury. It takes two external parameters （impact pressure and depth） and has a similar injury mechanism to clinical accelerating BSI. Moreover it is reproducible and stable, thus being be- neficial for exploring pathophysiological mechanism, diag- nosis and forensic identification of various degrees of BSI.展开更多
