ABSTRACT
Objective The aim of this study was to explore the effects of health education intervention on asthma control level for asthma patients through the survey of general demographic information,asthma clinical characteristics of patients with asthma,the Asthma Control Test (ACT),and pulmonary function examination.Methods 126 asthma patients were selected from the clinic and randomly divided into the health education group and the control group.All the patients were followed up for 3 months.In our study,we would scored them in terms of demographic data,clinical features of asthma,asthma cognitive level,medication compliance and Asthma Control Test (ACT) and pulmonary function examination before and after the health education for all patients respectively,and compared the data of the above parameters obtained before and after the intervention and the data from the health education intervention group and the control group.Results In our study,10 cases were lost to follow-up,and 116 cases completed the study at last.There were 68 patients in the health education intervention group and 48 patients in the control group.The results showed that patients with acute attack times,ACT score,pulmonary function indicators and asthma control situations of the health education intervention group after 6 months’ health education,were significantly improved,and the difference was statistically significant.Otherwise,comparison of the contents above of the control group before and after intervention,it was not statistically significant.Meanwhile,com-pared with the control group,the contents above of the health education intervention group were improved with statistically significant differences.Conclusions The standardized health education can improve the quality of life significantly,decrease the asthmatic symptoms,reduce the times of acute onset,which results in maintenance of asthma control,meanwhile the pulmonary function of patients with asthma will improve,so that more patients can live as normal or nearly normal people.
ABSTRACT
Objective To investigate the minimal inhibitory concentration (MIC) of Pseudomonas aeruginosa to antibacterial agents which were induced by disinfectants.Methods The susceptibility test of 68 strains from clinic was determined by VITEK-2 system.The MIC of povidone iodine,glutaraldehyde and chlorhexidine was determined by agar dilution method.68 strains were induced by different concentrations of three kinds of disinfectants for eight times.The concentration of three kinds of disinfectants was lower than their MIC.The MIC before and after inducement was determined by micro dilution.In the mean-while,strains of their MIC raised to antibiotics were inoculated on plate agar containing the PAβN which was the efflux pump inhibitor,in order to determine the phenotype of efflux pump.Results Six strains,MIC in 68 strains significantly changed after induction of disinfectants.The MIC of these six strains was higher than pre-induced to some antibacterial agents such as FQNs,cephems and carbapenem.The induction of povidone iodine and gilutaraldehyde were more obvious,and five strains,phenotype of efflux pump were positive after being induced by these two disinfectants.Conclusions The antimicrobial susceptibility of some Pseu-domonas aeruginosa will change after being induced by some disinfectants and the efflux pump will play an important role in this process.So the reasonable application of disinfectants were indispensable,in order to decrease the resistance and the opportunity of nosocomial infection.
