To explore the electromagnetic compatibility in the shelter hospital system to adapt it to the future complex electromagnetic environment. The factors for electromagnetic interference were analyzed, and some measures were put forward including separating the interference source from the sensitive device, setting up shielding space, applying grounding measures, eliminating interference signals by filtering and etc. The electromagnetic compatibility in the shelter hospital system was detected through electromagnetic self-compatibility test and electromagnetic environ-mental suitability test for external radio frequency. Simulations and tests proved that the failures and mal-re-sponse due to electromagnetic interference were avoided in the shelter hospital system. The electromagnetic compatibility scheme can meet the requirements of emergency medical facilities for electromagnetic protection in field conditions.

OBJECTIVE:To investigate the variance of antimicrobial resistance of Klebsiella.spp isolated in our hospital during the recent 5 years.METHODS:Disk diffusion test was used to study the anti microbial resistance.The results were evaluated based on the criteria recommended by American Clinical and Laboratory Standards Institute.The data analysis was performed using WHONET-5software.RESULTS:Atotal of 840 strains of Klebsiella.spp were collected fromour hospital during2003～2007,of which,59.3% were fromrespiratory secretion speci men,12.0%fromblood speci men,and10.1% from secretions.The detection rate of ESBLs-producing Klebsiella.spp was from51.0% to65.1%.No I mipenem-and Meropenem-resistant Klebsiella.spp strain was detected.Susceptibility test showed that Klebsiella.spp-producing ESBLs was multiple resistant,and the anti microbial resistance of Klebsiella.spp has increased year on year.CONCLUSION:Monitoring of the drug resistance of Klebsiella.spp should be strengthened.The variation of the anti microbial resistance of Klebsiella.spp should be noted so as to direct rational drug use in the clinic and prevent spreading of drug resistant strains.

OBJECTIVE: To investigate the change of the resistance of common pathogenic bacteria isolated in the First Clinical Hospital of Jilin University during the past 5 years to quinolones.METHODS: Disk diffusion test was used to study the susceptibility test,with the results evaluated based on US Clinical and Laboratory Standards Institute(CLSI).WHONET-5 software was used to analyze the drug resistance data.RESULTS: During 2003～2007,the detection rates of extended spectrum beta-lactamases(ESBLs)-producing Escherichia coli and Klebsiella.spp were 43.6%～60.1% and 51.0%～65.1%,respectively;the detection rates of methicillin-resistant Staphylococcus aureus(MRSA) and methicillin-resistant coagulase negative Staphylococcus(MRSCN) were 50.8%～83.3% and 80.0%～81.5%,respectively;the resistance of common pathogenic bacteria to quinolones showed an increasing tendency,much as in MRSA,MRSCN,feces enterococci,Enterococcus faecalis,and Escherichia coli.CONCLUSION: Monitoring of the resistance of common pathogenic bacteria to quinolones should be strengthened.The change of the antimicrobial resistance should be investigated in order to direct rational drug use in the clinic and prevent the propagation of drug-resistant strains.

Based on new material and technic, the design of general structure, stretcher fixture, vibration isolation, carriage baffle fixture, ergonomical parameters selection for a new kind of stretcher suspension named added equipment for transporting the wounded on the truck is carried out. The results of mechanical performance experiment, reliability experiment, road adaptability test, road comfort test, application experiment by troops indicate that the added equipment is safe, reliable, convenient for use and fairly comfortable to persons lying on it. Thus a new kind of equipment fit for the army to transport the wounded on the truck under the field condition is developed.

Objective To emphasize the correlation and concordance of electronic medical record through analysis of frequently asked problems on handwritten medical record.Methods The problems of electronic medical record were classified and found the typical cases to analyze.Results In order to improve the quality of medical record,the quality control of electronic medical record must be strengthened and the phenomenon that some doctors pay attention to hand-written med-ical record more than electronic medical record must be overcame.Conclusion The normative management of electronics medical is strengthened that is fundamental guarantee for paper-based medical records.

Objective:To explore epidemiologic features of primary aldosteronism (PA) in northern Jiangsu and using plasma aldosterone/renin activity ratio (ARR) combined plasma aldosterone level to screen PA patients among pa-tients with hypertension .Methods:A total of 2014 inpatients and outpatients with hypertension were collected from our hospital .Radioimmunoassay was used to measure plasma levels of renin and aldosterone and blood biochemical indexes ,then ARR was calculated .PA was diagnosed when ARR>240 and aldosterone>150 pg/ml .Results:A to-tal of 239 patients (11. 87% ) were complicated with PA among the 2014 patients with hypertension ,and it occupied 23.69% (145/612) among patients with refractory hypertension .Compared with pure hypertension group ,there were significant reductions in renin activity [ (2.18 ± 2.54) ng?ml-1 ?h-1 vs .(0.68 ± 0.49) ng?ml-1 ?h-1 ] and serum potassium level [ (3.96 ± 0.45) mmol/L vs .(3.54 ± 0.45) mmol/L] ,significant rise in aldosterone level [ (132.99 ± 104.25) pg/ml vs .(272.55 ± 154.68) pg/ml] and ARR [ (118.40 ± 109.4) vs .(463.19 ± 251.85)] ,P<0.05 or <0.01 ,and significant reduction in onset age of hypertension [ (49.37 ± 9.31) years vs .(39.69 ± 7.59) years] ,P<0.01. Patients complicated with hypokalemia occupied 33.47% among PA patients ,linear correlation a-nalysis indicated that serum potassium level was correlated with aldosterone level (r= -0.706 , P=0.001) .Conclu-sion:In northern Jiangsu ,PA occupies 11.87% among patients with hypertension and it occupies 23.69% among pa-tients with refractory hypertension .Therefore ,plasma ARR should be regularly detected to screen PA patients in patients with hypertension ,especially those with refractory hypertension .
