Objective To assess the quality grade of medical equipment timely so as to maintain strong battle effectiveness in troops.Methods According to technical standard promulgated by General Logistics Department,Medical Equipment Maintaining and Assessment flow was constituted and the corresponding software was developed.Results The management and assessment of medical equipment was more scientific and perfect,thus improving the working efficiency.Conclusion Proper management flow and software play an important role in improving the managerial quality and efficiency for medical equipment

Objective To study the electromagnetism environment of health equipment both in peace time and wartime,and give schemes.Methods The sources,types and harms of electromagnetic interference were analyzed.Methods for anti-jamming were discussed.Results Proper methods for anti-jamming were proposed.Conclusion Electromagnetic interference can be prevented effectively by using simple and convenient anti-jamming methods.

In recent years,great progress of medical equipment has been made in the army at the basic level.At the same time,there are also some new problems.This paper discusses these problems and suggests the countermeasures to them.

Aiming at the characteristics of combat readiness medical teams in military hospital,this paper designs a management system for hospital combat readiness.It can effectively manage such work in medical team as medical equipment,medicine,consumable,personnel,preparation,training,etc.It not only improves the equipment flow in storehouse but enhances the work efficiency.

Objective To explore the migration of Windows operating system to Virtual Linux operation system to solve the problems faced by the main server of No.1 Military Medical Project HIS.Methods The migration was fulfilled with x86 hardware platform,open-source Linux operating system and virtualization technology to meet the performance and reliability requirements of No.1 Military Medical Project System.Results The migration was completed successfully to Virtual Linux system.Conclusion The migration scheme meets the requirements of HIS on performances,reliability,stability and safety,saves the cost for informatization,and is of great practical value.

Objective To investigate the effects of constant magnetic field (CMF) on proliferation, apopto-sis and nitric oxide (NO) secretion of rat bone marrow-derived endothelial progenitor cells (EPCs) intervened by C-reactive protein (CRP). Methods EPCs were isolated from rat bone marrow by density gradient centrifugation and cultured on fibronectin-coated dishes. The cells were divided into five groups, i. e., control group, CRP (12 μg/ml) group, CRP plus CMF (0.1, 0. 5, 1.0 mT) groups. Samples were collected 24 hours after incubation. Cell proliferation was measured by MTT chromatometry. Apoptosis rate was detected by flow-cytometry. NO content of culture medium was measured by nitrate reductase method. Results As compared with control group, cell prolifer-ation in CRP group reduced significantly (0. 265±0. 008 vs 0. 316±0. 011, P < 0.05), NO secretion also de-creased significantly [(22.7±4.5) μmol/L vs (37.6±3.8) μmol/L, P < 0.05], cell apoptosis rate elevated sig-nificantly [(10.8±0. 8) % vs (4.2±0.5)% ,P < 0.05]. Cell proliferation in CRP plus 0. 5 mT or 1.0 mT CMF group (0. 295±0. 009,0. 302±0. 010) were much more than those in CRP group (P<0.05), NO secretion contents [(28.3±4.9) μmol/L, (29.2±5.6) μmol/L]were also much more than those in CRP group (P < 0.05) , apopto-sis rate [(7.4±0.5)% ,(6.9±0.6)%]was significantly lower than that in CRP group (P <0.05). Conclusion CMF at intensity of 0.5 mT and 1.0 mT can antagonize the effects of CR, promote proliferation of EPCs and secretion of NO and inhibit apoptosis rate of EPCs.
