Objective:To develop a materials management information system for military hospital warehouse of combat readiness based on RFID so as to enhance the management of military medical corps for materials of war preparation.Methods:RFID(Radio Frequency Identification) tags were attached on war materials and the information could been read by bar-code reader. SQL Server 2005 was used as the backend database, and VC# was combined with RFID to develop the software system.Results: This research has developed a materials management information system for military hospital warehouse of combat readiness based on RFID and this system could achieve informatization for information management, management of out and in warehouse, emergency plans management and forewarning management. Through manoeuvre, the average time of war materiel out warehouse has saved 12min.Conclusion: The research and development of information management system for materiel information of hospital warehouse for combat readiness has reference value for the application of researching RBID technique in material management.

Objective To explore the optimal method and condition for controlling release of vincristine (VCR) from VCR-loaded erythrocytes and enhancing the stability of carrier erythrocytes. Methods Erythrocytes were loaded into human erythrocytes using the modified hypotonic pre-swelling and isotonic resealing technique, and then with VCR, and they were treated with glutaraldehyde in concentration of 0.16% and 0.25% respectively. After storing at 4℃ for indicated time, the amount of VCR was determined with HPLC to compare their drug-release rate, and the degree of hemolysis in the supernatants was observed to compare the fragility of VCR-loaded erythrocytes treated with 0.16% glutaraldehyde with that with 0.25%, VCR-loaded erythrocytes treated with PBS, and VCR-loaded erythrocytes exposed to different hypotonic sodium chloride in different concentrations. Results The VCR-accumulated release rate increased in glutaraldehyde-treated VCR-loaded erythrocytes as well as untreated group during preservation. The VCR-accumulated release rate of 0.25% glutaraldehyde-treated group decreased by 71.67?4.20%, which was significantly slower than untreated VCR-loaded erythrocytes and 0.16% glutaraldehyde-treated group. After storing at 4℃ for 21 days, no significant changes at erythrocyte morphology was found in VCR-loaded erythrocytes treated with 0.25% glutaraldehyde, whereas untreated VCR-loaded erythrocytes and those treated with 0.16% glutaraldehyde can be stored only for 5d and 7.5d respectively. As compared to un-treated VCR-loaded erythrocytes, no significant change of osmotic fragility was seen in 0.25% glutaraldehyde-treated group, but significant increase in osmotic fragility was seen in 0.16% glutaraldehyde-treated group. Conclusion 0.25% glutaraldehyde could optimally block the membrane of VCR-loaded human erythrocytes and enhance their stability.

Purpose:To evaluate the thrombolytic effect of transcatheter intra-arterial infusion of urokinase injectio salviae miltiorrhizae and heparine.Materials and methods:A 5F catheter was delivered to the thrombotic site via femoral artery,then infused urokinase.Injectio salviae mihionrrhizae via catheter.During and after the procedure heparin was given for antico- agulation.Finally to evaluate the effect by femoral arteriograms.Results:Blood circulation of 10 eases were inproved with complete pateney.One case wasn't very fluent and the last one remained obstructed.Total effective rate was 92%.Conclusion:Transcatheter Intraarterial thrombolysis by combing urokinase,injeetio salviae miltiorrhizae and heparin was a effective and safe theraputic method.

Objective To investigate the optimum techniques for processing Yuhuanlian with microwave. Methods Nine samples were obtained by orthogonal design. Thin-layer chromatography was used to determine berberine in Yuhuanglian. The content of berberine was taken as the index for the evaluation on the superiority of processing techniques. Results The optimal processing techniques for Yuhuanglian with microwave was suggested as follows:A2B2C3, moistened for 90 minutes, put 2 cm thick, with 80% of the microwave, heating 3 minutes. Conclusion The method is simple, easy to control, easy to use, easy to promote, and the quality of processed products is better.

OBJECTIVE:To study the protective effect of butylphthalide on the apoptosis of human umbilical vein endothelial cells (HUVECs) induced by Aβ1-42 and its mechanism. METHODS:HUVECs were divided into normal control group,Aβ1-42 group,TAK242 group(10 nmol/L),DMSO group(1‰DMSO)and butylphthalide low-concentration,medium-concentration and high-concentration groups (40,80,160 μg/L). Except for normal control group and DMSO group,other groups were given 50 μmol/L Aβ1-42 to culture HUVECs for 24 h. TAK242 group,DMSO group and butylphthalide low-concentration,medium-concentra-tion and high-concentration groups were given relevant concentration of drugs for 30 min,with 3 holes for each concentration. The cell viability was determined by CCK-8 assay;cell apoptosis was observed by Hochest 33342/PI double staining;the cell apoptotic rate was detected by AnnexinⅤ-fluorescein isothiocyanate (FITC) flow cytometry;the protein expression of TLR-4 and COX-2 were determined by Western blot assay;the contents of IL-1 and TNF-α were detected by ELISA. RESULTS:Compared with nor-mal control group,cell viability of HUVECs were decreased in Aβ1-42 group;while apoptotic rate,protein expression of TLR4 and COX-2,the contents of IL-1 and TNF-α were increased. Compared with Aβ1-42 group,cell viability of HUVECs were increased in TAK242 group and butylphthalide low-concentration,medium-concentration and high-concentration groups;while apoptotic rate, protein expression of TLR4 and COX-2,the contents of IL-1 and TNF-α were decreased,with statistical significance(P<0.05 or P<0.01). CONCLUSIONS:Butylphthalide can reduce HUVECs apoptosis induced by Aβ1-42,which may be related with inhibiting the expression of TLR4,COX-2 and inflammatory factors.

Objective To study the effect of p38MAPK on the activity and c-myc protein expression in rat acetaldehyde-induced hepatic stellate cell(HSC),and to investigate the alcoholic liver fibrosis related mechanism.Methods The different concentrations of SB203580 as the p38 specific blocker was adopted to conduct the intervention on rat acetaldehyde-induced HSC.The cellular mor-phological change was observed by the microscope.The cell proliferation was detected by MTT,the cell cycle was analyzed by flow cytometry(FCM),and the expression of c-myc protein was examined by the SABC method.Results (1)after acetaldehyde stimula-tion,HSC was increased in size and proliferated rapidly,but with the added SB203580 concentration increase,the cellular prolifera-tion was slowed down,the cells size was diminished and the deformed cells were increased.(2)The proliferation of acetaldehyde-in-duced HSC was inhibited by different doses of SB203580,and the higher concentration has the more significant inhibiting effect.(3) With the SB203580 concentration increase,the cells at the phase G0 and G1 were increased,while the cells at the phase S were de-creased,at the same time the expression positive rate of c-myc protein was decreased.Conclusion Blocking p38MAPK pathway ac-tivity could inhibit the proliferation of acetaldehyde-induced HSC,which may be related to the down-regulation of C-myc protein ex-pression and blocking the DNA synthesis in cells entering from G0/G1 phase to S phase.
