Objective To evaluate the efficacy of surgical treatment of Ebstein's anomaly with modified Carpentier's repair technique. Methods ⑴Enlarging the anterior leaflet with a pericardium patch; ⑵The edge of posterior leaflet was sewed to the edge of anterior leaflet or septal leaflet in favor of enlarging the area of leaflet; ⑶Annulus was reinforced with the terylene ring covered with pericardium; ⑷Adjustable Devega's procedure. Results 31 patients with Ebstein's anomaly underwent modified Carpentier's repair operation from Jan 1992 to May 2003 in our institution. There was one patient died after operation because of a fatal cardiac dysfunction, and no late deaths. During the followed-up period of 6~94 months, all surviving patients had a marked improvement of heart function, and 6 cases were in class I, 21 in class II and 3 in class III. There were no postoperative rhythm disturbances. Conclusion The modified Carpentier's repair technique is feasible and possesses a good outcome.

Objective To realize the integration of PACS and HIS. Methods Powerbuilder was used in designing the electronic application system. Synchronization of PACS and HIS were accomplished by Oracle stored procedures. Results The integration of PACS and HIS were implemented successfully in Xijing Hospital and satisfied results were achieved. Conclusion The successfully integration of diverse systems should be based on the circumstance of hospital,led by information department,and discussed and demonstrated by relative departments. At the same time,the principal of high availability and low dependence among diverse systems should be followed. The alternate periods of old and new work flows should be decreased on the basis of practical software and reasonable procedure.

Objective To develop a portable acoustic output measurement system in order to satisfy the requirements of military itinerant inspection. Methods A hydrophone was used as energy converting equipment to collect wave of acoustic pressure in the field of ultrasound. Through some calculations using approximated formulas, a serious of acoustic output parameters were achieved. Results Main acoustic output parameters could be measured with permitted error. Conclusion This method is feasible, which can make up for the defects of current measurement.

Objective: In order to understand temporal and spatial distributions of alternating electromagnetic field (AEMF) of a coil thoroughly, the 3-D finite-element models of this kind of Biomagnetic Fields are established and analyzed for the research on bioeffect of magnetic field on microcirculation. Methods: Designing CAD models, setting boundary conditions, meshing models and obtaining numerical solutions were completed all within Comsol Multiphysics in terms of the theory of electromagnetic field. Results: Axial and radial plot of spatial attenuation rate of the AEMF, which were accordance with measured data, were simulated while the temporal and spatial distributions of AEMF were acquired. Conclusion: Models of 3-D finite-element of this kind of biomagnetic fields which appeared to exactly simulate the real magnetic field were first established systematically, and solved the placing problem of magnetic fields for the research on bioeffect of magnetic field on microcirculation and provided platforms for the simulation of hemodynamic of blood flow in the magnetic field.
