Objective:To meet the requirements of hospital consultation management, promote the hospital consultation work in order to make the hospital a huge consultation data processing becomes simple, reduce the burden of management personnel and medical personnel management information system.Methods: Through the on-site investigation to collect the needs of the management personnel and the clinical front-line personnel, visit the application of other hospitals, and combine with the actual work, the development of suitable for hospital consultation management information system, the consultation for effective management and monitoring.Results: Based on the analysis of the needs of all kinds of personnel and consultation management information system, the basic function of the consultation management information system is realized.Conclusion: The realization of the consultation management information system can meet the needs of all kinds of people in the process of hospital consultation management, so as to meet the high efficiency management of hospital consultation, so as to improve the level of hospital information resource utilization.

BACKGROUND: As a metal internal fixation material, magnesium alloy has more unique advantages, such as biodegradability and elastic modulus. The elastic modulus of magnesium alloy is similar to the compact bone,which is enough to avoid stress-shelter effect. However, biological activity represents bonding ability with the bone in the body for fracture fixation materials, which is of great significance for studies on new kinds of magnesium alloys.OBJECTIVE: To observe the microstructure of Mg-Zn-Gd alloys and to analyze the corrosion products on the material surface after immersed in simulation body fluid.METHODS: The Mg-Zn-Gd alloys were manufactured by the method of fusion casting. Scanning electron microscope with spectrometer was applied to observe microstructure and distribution of precipitated phase and corrosion products of Mg-Zn-Gd alloys in simulated body fluid.RESULTS AND CONCLUSION: The Mg-Zn-Gd alloy was composed of α-Mg solid solution containing Gd and Zn elements and eutectic structure. The eutectic structure was almost feathery, oval-shaped, herringbone-shaped and strip-shaped along the grain boundary. The main ingredients of eutectic structure included Mg, Zn and Gd elements.Deposition layer was composed of O, Mg, Ca and P elements on the surface of Mg-Zn-Gd alloy after 72 hours soak in Hank's solution. X-ray diffraction analysis showed that film layer contained Mg(OH)2 phase, which promoted calcium salt deposition and reduced the corrosion rate. So Mg-Zn-Gd alloy can obtain better biological activity.

BACKGROUND:In recent years, vacuum sealing drainage technology has been widely used in the treatment of orthopedic wounds or to facilitate skin graft survival, both of which have achieved good results.
OBJECTIVE:To observe the curative effects of vacuum sealing drainage technology in the wound healing after limb open fractures, soft tissue defects, pressure sores, and chronic osteomyelitis.
METHODS:Fifty-four patients of fractures combined with soft tissue defects, postoperative exposed bone, osteomyelitis, a large area of pressure ulcers or severe infections, selected from the 273rd Hospital of PLA, were randomly divided into test and control groups according to the wishes of patients. The test group included 36 patients who were treated with vacuum sealing drainage using polyethylene ethanol hydration seaweed salt after debridement, and the control group included 18 patients who were treated with conventional dressing. Wound cleaning time, number of dressings, and wound healing time were detected and compared in the two groups.
RESULTS AND CONCLUSION:Compared with the control group, the wound cleaning time and wound healing time were shorter in the test group, and the number of dressings was also decreased in the test group (P<0.05). After removal of sponge dressings, in the test group, wound granulation was fresh and grew obviously with no exudates after the necrotic residue was removed and vacuum sealing drainage was changed. For the bone exposure patients, the wound area was reduced, or even there was no exposed bone any more. After skin grafting, vacuum suction and pressure due to vacuum sealing drainage technology made al skin grafts survive. In the patients with chronic osteomyelitis, the exudates were gradual y reduced until disappeared after vacuum sealing drainage was exchanged three or four times, and pathogens were not found in bacterial culture. After combined treatment of debridement and vacuum sealing drainage, there were many fresh granulations in the patients with large areas of pressure sores;after replacement of vacuum sealing drainage several times, the granulation grew to the same height with the surrounding skin.
