Objective To evaluate endovascular aortic repair for retrograde Stanford type A aortic dissection with an entry tear in the descending aorta.Methods From April 2006 to Dec 2012,31 patients with retrograde type A aortic dissection were treated with endovascular technique.22 patients had pleural effusion,14 patients had patent false lumen in the ascending aorta.Emergency operation was performed in 2 patients with acute right renal artery and right common iliac artery ischemia respectively.29 patients received endovascular treatment after 3 weeks conservative treatment.Chimney technique was used in 3 patients.Results All procedures were technically successful without severe complications.Ascending aorta recovered 1-3 months after operation.Pleural effusion subsided 3 days to 3 weeks after endovascular treatment.During follow-up of (31 ± 18) months,no severe complications developed,all the stent-grafts placed by chimney technique were patent.Conclusions Endovascular aortic repair can be used in the treatment of retrograde Stanford type A aortic dissection.Chimney technique can be used to reconstruct supra-aortic branches.

Objective To evaluate surgical management of ruptured abdominal aortic aneurysm (RAAA).Methods Clinical data of 36 RAAA patients undergoing emergent graft replacement or endovascular aortic repair (EVAR) from May 2002 to July 2013 were retrospectively analyzed.25 and 21 patients were associated with hypertension and chronic obstructive pulmonary disease respectively.33 patients were treated with graft replacement.3 patients received endovascular treatment and 1 patient converted to open surgery.Results Perioperative death occurred in 3 patients including severe hemorrhagic shock in 1 patient,cardiac arrest in 1 patient and multiple organ failure in 1 patient.During follow up for 3 to 61 months,no operation related complication,such as artificial graft infection happened.Conclusions Emergent operation including open surgery and EVAR is crucial for RAAA treatment.Early diagnosis,excellent operative techniques and effective perioperative management are measures conducive to lowering the mortality rate of RAAA.

Objective To develop a self-help report printing system for management of inspection data and improvement of inspection workflow. Methods The self-help report printing system was compiled based on LIS with ORACLE database management system and was coded with PowerBuilder9.0 development kit. Results The information exchange in self-help report printing system and LIS are implemented successfully, and can print out inspection report with electronic signatures. Conclusion The self -help report printing system simplifies the reporting process and improves work efficiency through application in hospital.

Objective To develop a bar code management system for two-way communication between XE-2100 hematology analyzer and LIS.Methods The relevant databases/tables were set based on PowerBuilder 7.0.The bar code ActiveX MSBCODE9.OCX was used for creating bar codes from patient information and test item information.Codes of all objects were translated to an executive file and DLL files.Results The results showed that the bar code was clear with high discernable rate,stable two-way communication and safe data storage.As the only identifier for specimen,the bar code improved work efficiency and management level,and avoided errors in sampling procedure.Conclusion The application of bar code technique to clinical hematology examination normalizes the workflow and provides a new mode for automatization and standardization management.

Objective To develop a software for communication interface of laboratory analyzer for single-way or two-way communication of laboratory analyzer so as to ensure the data accuracy.Methods Based on PowerBuilder 9.0,MSCOMM.OCX was programmed to connect PC and the laboratory analyzer by right settings of communication parameters.Results All data were received stably and accurately without errors in running.This software replaced manual recording absolutely.Conclusion The communication interface software for laboratory analyzers not only realizes automatic data acquisition to the greatest extend and ensures the accuracy,but also makes the laboratory working procedure more reasonable and data management more standardized.

Objective To analyze the application of bar code mode in LIS and help select a fit bar code mode for the hospital. Methods The mode of print bar code was chosen on the base of LIS that was programmed with ORACLE database and PowerBuider9.0 so as to manage laboratory information. Results The bar code management in LIS was realized and no- paper thoroughly in hospital. Conclusion The print bar code mode is more suitable for information-based hospital.

Objective To evaluate endovascular repair combined with assistant techniques for the treatment of Stanford type B aortic dissection involving aortic arch.Method From July 2002 to June 2010,46 patients of aortic arch dissection with the primary entry tear next to the orifice of left subclavian artery,were treated with endovascular repair.Left subclavian arteries were covered with TEVAR in 43 cases.PDA occludes were used in 6 patients.Nine patients received extrathoracic supra-aortic branches bypass.Double-barrel technique was performed in 8 patients.Fenestrated stent graft was used in 1 patient.Result All patients survived and were followed up for 2 to 76 months.No severe neurological complications happened.All synthetic grafts and carotid artery stents were patent.Type Ⅱ endoleak occurred in 10 patients,among them 6 received PDA occlude implantation in the left subclavian artery,and 2 patients recovered by conservative treatment.Nine patients suffered from ischemia of the left upper extremity,and 8 of them were treated with conservative method,one received bilateral subclavian artery bypass because of severe ischemia after endovascular treatment.In follow-up,all of the stent-grafts and grafts were patent.In the descending aorta,the diameter of true lumen increased significantly and the diameter of false lumen shrank gradually.Conclusions Endovascular aortic repair combined with extrathoracic supra-aortic branches bypass,PDA occlude,double-barrel technique and fenestrated technique is a safe and effective method for Stanford Type B aortic dissection involving aortic arch.

OBJECTIVETo investigate the emergency treatment for large amputated ear defect.

METHODSFrom Feb. 2010 to Oct. 2013, 5 cases with large unilateral amputated ear defects were treated. The amputated auricular cartilage was replanted subcutaneously in mastoid area at the first stage. Cranioauricular sulcus was reconstructed and skin grafting was performed at the second stage.

RESULTSAll cases were followed up for 3-6 months with satisfactory result. The reconstructed helix, scapha and cavity of auricular concha had similar color and elasticity as the ear at healthy side. Scar at donor sites, such as inguinal region and armpit, was inconspicuous.

CONCLUSIONSThe method of auricular cartilage replantation is an effective way for emergency treatment of large amputated auricular defect with less morbidity at donor site.

Hyaluronan acid sodium gels are used in ophthalmic surgery, orthopedic treatment and cosmetic surgery. In 2009,there were 12 domestic manufacturers in China producing 33 kinds of products. 23 kinds of imported products were allowed by SFDA to sale in the meantime. Since manufacturers use different production processes, product performances are quite different. According to the GB/T 16886. 1-2001, we designed a pilot program to evaluate the sodium hyaluronate gel products comprehensively in this paper. The results showed that, except chromosome aberration test of gel A and subchronic systemic toxicity of gel C appeared positive, the remaining samples of the test results were negative. This article provides a reference to write standard of cross-linked hyaluronic sodium gel and the revision of standard YY0308-2004.
