Objective To construct a safe data-back-up system with disaster-tolerant ability. Methods Based on the concept of data back -up, the paper puts forward several data back -up modes in common use, and carries out corresponding comparison. Results The author synthesized these back -up modes into an ideal, feasible, and highly secure system architecture with disaster-tolerant ability. Conclusion Constructing a safe data-back-up system are becoming the mostly indispensable elements for the hospital informationization. It can avoid the single fault in the hardware level, and also can repair the logical data fault in the software level.

Objective To explore the theory and measures of armymen's clinical flow through information technology based on an exclusive armymen clinical area.Methods On the basis of No.1 Military Medical Project,such system was developed as automatic medical service classification & guide system,clinic backstage & auto-medicine provision system and comprehensive clinical service system in order to optimize medical service for armymen.Results By integrating the armymen's clinical information system,Navy General Hospital optimized comprehensively the clinical flow of registration,waiting,diagnosis,pricing,medicine pick-up,etc.Therefore,the efficiency of medical service for the army was greatly improved.Conlusion The full application of information technology will make an improvement in clinical flow and provide better service to army patients.

Objective To improve the reliability of the core database system by ameliorating the scheme of the server system architecture. Methods Combined with practice of the hospital informatization, the security and potential hole of the database server system were analyzed and evaluated. Results Aimed to deal with the security hidden-trouble, a mini-server was adopted instead of PC server, while SAN(Storage Area Network) was utilized instead of RAID-5, and mirror copy technique was used to implement the real-time hot copy of the data. Conclusion Consequently the reliability of the system has been greatly improved.

Objective To study the correlation between immune imbalance mediated by Th 17 and Treg cells and impaired lung function in patients with chronic obstructive pulmonary disease ( COPD ) . Methods Ninety-five patients with moderate or severe COPD , thirty-five smokers with normal lung function and thirty-one healthy non-smokers from Yinzhou People′s Hospital from January 2009 to December 2012 were recruited in this study .The percentages of circulating Th 17 and Treg cells in peripheral blood samples were determined by flow cytometry .The concentrations of cytokines in serum samples and supernatants of in-duced sputum samples were measured by enzyme-linked immunosorbent assay (ELISA).The expression of ROR-γt and Foxp3 at mRNA level in peripheral blood mononuclear cells ( PBMC) were determined by quan-titative real-time PCR.The potential association between ratios of Th 17/Treg cells and lung function was evaluated.Results Compared with smokers and healthy subjects , patients with moderate or severe COPD showed high levels of Th17 cells, IL-17A, IL-6 and IL-23, and an up-regulated expression of ROR-γt at transcriptional level .However, the percentage of Treg cells , IL-10 level and the expression of Foxp 3 at mRNA level were down-regulated in patients with COPD .The levels of cytokines in supernatants of induced sputum samples varied in the same way as that of Th 17/Treg in peripheral blood samples .The ratio of Th17 to Treg cells was negatively correlated with the values of forced vital capacity ( FVC) , forced expiratory vol-ume in one second (FEV1), and FEV1/FVC.Conclusion Th17/Treg cells imbalance was closely associ-ated with the deterioration of pulmonary function in patients with moderate or severe COPD .Th17/Treg cells imbalance might be involved in the progression of COPD .

Objective To evaluate the effect of health education on preventing birth defects in community in terms of knowledge, attitude and practice (KAP) for married women in reproductive age. Method A self-designed general information form and a questionnaire on KAP of married women′s preventing birth defects were used to investigate the KAP among 300 married nulliparous women. Result The average rate of cognitive knowledge of birth defects was 60.8%, the average rate of cognitive behaviors was 59.2%, and the average rate of cognitive attitude was 67.4%. Conclusion In order to reduce the rate of birth defects and improve the quality of births, we should implement three-level prevention education system, enrich the health education methods to enhance the knowledge, attitude and behavior of married women.

Objective To preliminarily analyze the credibility and validity of Chinese Medical Constitution Questionnaire(CMCQ).Methods CMCQ was used to investigate the distribution of Chinese medical constitution types of 450 women inpatients with postoperative nausea and vomiting (PONV) after gynecologic laparoscopic surgery from March to October of 2013.Credibility and validity were analyzed by Cronbach's α coefficient and factor analysis.Results Mixed constitution was identified in 184 (40.9％) patients.Cronbach's α coefficient of two dimensions (yang deficiency and qi stagnation) of CMCQ was proper,being 0.815 and 0.803 respectirely,while that of the dimension of harmony type was the lowest (0.514).The total variance explained by 9 common factors extracted from the results of factor analysis was only 48.5％.Conclusion CMCQ may need further revision based on the results of clinical application.

Objective To discuss how to improve the stability,reliability and security of the core servers of hospital information system.Methods Flaws on security were analyzed objectively in hospital server system adopting 'PC server & local hardisk' scheme.New schemes were put forward including both hot standby scheme based on concentrated storage and full redundancy scheme based on'minicomputer & diskette array'.Results It is proved that the full redundancy scheme is reasonable in theory,and usable in practice.Conclusion The mode of'minicomputer & diskette array' can effectively enhance the stability,reliability and safety of core servers.

Objective To develop a software through which transfusion labels can be created and printed automatically based on No.1 Military Medical Project,in order to resolve the problems of time-and-labor-consuming and errors due to transcription. Methods Based on No.1 Military Medical Project,the software of creating and printing transfusion labels was developed using PB computer programming language. Results The software can effectively avoid the errors due to copying transfusion labels by hand and save much time and effort. It optimizes nurses' working procedure. Conclusion The software is very practical for all the hospitals using the No.1 Military Medical Project.
