This article discusses how to handle one or more block corruptions on an Oracle data file and describes some main methods for data extraction.

The anesthetists not only pay attention to the exploitation and application of the information resource but also rely more and more on the convenience caused by the informatization. Based on HIS, LIS, and PACS, the Anesthesia information system has been constructed in order to guarantee the quality and safety of the anesthesia. The Anesthesia information system shares the information with HIS and LIS and manages the medical information such as the surgery and anesthesia closely. The paper introduces the notion of the anesthesia information system and its main function and also the predicted effect during the management of the anesthesia information system. Meanwhile, some problem about the application has been mentioned.

OBJECTIVE:To develop the drug traceability management system in outpatients of medical institutions,and gradu-ally improve its traceability management. METHODS:Based on barcode technology,drug traceability management system in outpa-tients of medical institutions was independently developed,introducing it from system environment,framework design and system function,and the application results were evaluated in terms of differences in dispensing time,deployment error,drug withdrawal treatment and applicability investigation. RESULTS:The system was developed on hospital information system network environ-ment,which was designed by combination of client/server(C/S)network system(B/S)and set function modules as follows as role rights management,data extraction,information control,data acquisition and data query. The system can match with drug electron-ic surveillance code,commodity code and other traceable barcodes,achieve drug tracing from hospitals to users through software interaction,as well as the computer-aided calibration in dispensing to effectively reduce outpatient's dispensing error. The average time for each outpatient prescription prolonged 9 s after using the system;24 dispensing errors and 4 non-normal withdrawals were prevented within 1 month;100% surveyed pharmacists expressed approval for the system's applicability. CONCLUSIONS:The system can achieve the drug suitability management in outpatients,which has shown good applicability and further improved drug safety management and control capabilities in medical institutions.

Objective To upgrade No.1 Military Medical Project from Oracle8i to Oracle10g. Methods Through the tools of Exp/Imp and Toad, the database migration was realized. Results Oracle database was upgraded from Oracle8i to Oracle10g successfully. Conclusion The method is simple,easy to operate and suitable for application.

Current hospital information system has to be reconstructed to satisfy futural requirements. The reconstruction improves the network structure, network performance, bandwidth, manageability and safety of current system, and makes it reliable and expandable.

Objective To describe the application situation, existent problems and insufficiencies of the electronic medical record (EMR) based on XML, and discuss the future development and requirement of EMR. Methods In recent three years, the application practice and current development condition of EMR based on XML were summarized. Results The EMR based on XML was provided considerable convenience and advantage for writing of medical record and the monitor of medical quality. Conclusion The electronic medical records are an important part of client information system (CIS), has become a necessary part of hospital informationization, and its extensive application has a long way to go.

Heparin is a very important anticoagulant drug. Currently, heparin is mainly extracted from porcine mucosa. However, animal-derived heparin shows low anticoagulant activity due to the low proportion of the anticoagulant active unit, the GlcNS6S-GlcA-GlcNS6S3S-Ido2S-GlcNS6S pentasaccharide. In this study we proposed an enzymatic strategy to sulfate the animal-sourced heparin to increase the proportion of anticoagulant pentasaccharide and the anticoagulant activity. First, three sulfotransferases HS2ST, HS6ST, and HS3ST were expressed tentatively in Escherichia coli and Pichia pastoris. After measuring the sulfotransferase activity, we confirmed P. pastoris GS115 is the better host for sulfotransferases production. Then, the maltose binding protein (MBP) and thioredoxin (TrxA) were fused separately to the N-terminal of sulfotransferases to increase enzyme solubility. As a result, the yields of HS2ST and HS6ST were increased to (839±14) U/L and (792±23) U/L, respectively. Subsequent sulfation of the animal-sourced heparin with the recombinant HS2ST, HS6ST and HS3ST increased the anticoagulant activity from (76±2) IU/mg to (189±17) IU/mg.
