Objective To discuss the possibility and efficiency by using Six Sigma method.Methods By using"five steps" of Six Sigma,management of medical consumable materials storehouse was improved continuously.Such Sigma levels before and after the implementation in 6 months were compared as satisfaction for medical service,supply punctuality,rate of high-quality products,and the realization of"Zero Storage".Results All Sigma levels were raised.Conclusion The method of Six Sigma fits for the storehouse management of medical materials and can improve the management quality.

Objective To detect the expression of histone deacetylase 6 (HDAC6) and its significance in non-small cell lung cancer (NSCLC).Methods The expression of HDAC6 was measured by SP staining in 70 cases of NSCLC and 18 cases of normal lung tissues.Results Positive rate of HDAC6 immunostaining in NSCLC was 58.57％,which was significantly higher than 16.67％ in normal lung tissues(P ＜0.01 ).No correlation was found between HDAC6 expression and the age,sex,differentiated level,histological type ( P ＞0.05).But the expression level of HDAC6 was closely related to clinical stage and lymph node metastasis in NSCLC patients ( P ＜ 0.05 ).Conclusion HDAC6 over expression may be related to the pathogenesis and development of NSCLC.

〔Abstract〕 The paper introduces the connotation of digital learning environment and digital scientific research environment, analyzes the strategies of constructing digital learning environment and digital scientific research environment in hospitals, including hospital librar-ians taking part in scientific research knowledge service, doctors, teachers and researchers participation, creating personalized scientific research information environment, etc.

Objective To investigate the significance of the soluble Apo-1/Fas(sApo-1/Fas) in differentiating tuberculous and malignant pleural effusion.Methods The level of sApo-1/Fas was detected by enzyme linked immunosorbent assay(ELISA).in serum and pleural effusion of 50 cases with malignant pleural effusion and 48 cases with tuberculous pleural effusion.Results The level of sApo-1/Fas in the serum and pleural effusion of malignant pleural effusion patients were ( 16.3 ± 2.5 ) μg/L and ( 38.6 ± 13.5) μg/L,significantly higher than those of tuberculous patients with pleural effusion( all P ＜ 0.05 ).The difference of rates of serum and pleural effusion in malignant pleural effusion and tuberculous pleural effusion patients was significant( P ＜ 0.05 ).The sensitivity,specificity and accuracy of sApo-1/Fas in serum and malignant pleural effusion were 66.0％ and 93.8％ and 79.6％.Conclusion The detecting of sApo-1/Fas may play some role in differentiating tuberculous and malignant pleural effusion.

The basic principles and methods of information classification and encoding, as well as the present situation of classification of medical consumable materials, are introduced. By adopting multi-stage classification and encoding structure to information of medical consumable materials, the classification and encoding become more scientific, flexible and practical, which avails the informational management of medical consumable materials.

Objective To discuss the management specifications of medical device application. Methods The article discussed the management specifications of medical device application, such as equipping principle, bar code management, annual assessment, and secondary warehouse, proposed beneficial plan and steps. Results With further implementation, it will enable the management of medical device application more refined, even more targeted and effective. Conclusion The equipment management regulations relates to a number of policy requirements which belongs to different countries, and it waits for consummating unceasingly.

Objective To discuss the specification of centralized management of hospital medical equipment to enhance the efficiency and economical benefit.Methods Centralized management center of medical equipment and general medical equipment leasing system were established.The environment requirements,economic accounting and data statistics were also discussed.Results The utilization rate of medical equipment was enhanced greatly,and purchase cost was decreased.Conclusion Hospital administrators can find reference to serve for first-line clinician.

Objective: With the increasing amount of medical materials used in the hospital,they are becoming one of the major sources of medical risks.How to control this risk has become a common concern in the medical world.The authors investigated how to enhance the safety and validity of medical materials.Methods: We established a total quality control system for medical materials to keep them under strict quality control at all stages,and a monitoring and reporting system as well to prevent undesirable consumption of medical materials.Results: The quality of medical materials was insured,and medical material-related accidents were prevented.Conclusion: The quality control system greatly improved the application safety of medical materials in the hospital.

ObjectiveTo detect serum soluble B7-H4 (sB7-H4) levels in patients with non-small cell lung cancer ( NSCLC ) and explore its clinical significances.MethodsThe sB7-H4 levels the sera of in 102 NSCLC patients,60 benign lung disease patients and 90 healthy controls were determined by ELISA.The relation between serum sB7-H4 levels and NSCLC of pathological staging was analyzed by use of t test.ResultsThe serum sB7-H4 levels in NSCLC,benign lung disease and heathy control groups were (45.61 ±5.67 ),( 30.14 ± 3.51 ) and ( 28.52 ± 4.76 ) μg/L,respectively.The levels of NSCLC group were significantly higher than those of benign lung disease and healthy control groups ( t =2,59 and 3.61,P ＜ 0.05 ).The serum sB7-H4 levels of Ⅲ/IV stage NSCLC patients ( 63.93 t 4.76 ) μgL,with lymph node metastasis (61.73 ±3.97) μg/L and before operation patients (63.29 ±6.19) μg/L were relatively higher thanthose inthe Ⅰ/Ⅱ stage(35.12 ± 3.88 )μg/L, without lymphnode metastasis (40.26 ± 5.39 ) μg/L,after operation ( 40.51± 4.08 ) μg/L.There were significant difference ( t =6.78,5.73 and 3.67,P ＜ 0.05 ).Conclusions Serum sB7-H4 of NSCLC patients increases significantly and correlates with clinical stages and therapeutic conditions.Detecting on sB7-H4 is helpful for lung cancer diagnosis and therapeutic effect evaluation.
