RESUMO
Objective To study the clinical significance of plasma N-teminal pro brain natriuretic peptide (NT-pro-BNP) level in diagnosis and evaluation prognosis of patients with different heart failure.Methods Plasma NT-pro-BNP level was detected and compared in all patients at the first day and a week after the patients' condition turn better.Results The level of plasma NT-pro-BNP for the high blood pressure's heart disease and the chronic heart failure of coronary heart disease and the chronic heart failure of cor pulmonale were significantly higher than normal (t =2.98,t =2.98,t =2.98,P ＜ 0.01).The level of plasma NT-pro-BNP was reduced after treatment (t =2.56,t =2.75,t =2.88,P ＜ 0.05,P ＜ 0.01,P ＜ 0.01).The level of plasma NT-pro-BNP was gradually increased by the increased degree of the heart failure(t =2.78,P ＜ 0.05).Conclusion The levels of plasma NT-pro-BNP at acute stage for the high blood pressure's heart disease and the chronic heart failure of coronary heart disease and the chronic heart failure of cor pulmonale were increased obviously and descend by the patients' condition return.The level of plasma NT-pro-BNP can monitor patients' condition and estimate the heart failure patients' prognosis.
RESUMO
Objective To investigate the curative effect of noninvasive positive pressure ventilation combined with aerosol inhalation of budesonide on patients with severe asthma.Methods One hundred and twenty-one patients with severe asthma were randomly assigned to two groups.Both groups were treated with noninvasive positive pressure ventilation based on routine treatment.In addition,patients in the treatment group were given aerosol inhalation of 2 ml budesonide and 2 ml NS,two times each day,14 days for a course.Clinical symptoms improvement and arterial blood pressure changes of two groups before and after treatment were studied to compare the curative effect of the treatments in the two groups.Results There were no significant differences in pH,PaO2 and PaCO2 between the treatment and the control groups(P ＞ 0.05).After one course of treatment,the treatment group had significantly higher levels of pH(7.43 ± 0.04 vs.7.34 ± 0.02,t =3.423,P ＜ 0.05) and PaO2 ( [77.4 ± 16.7 ] mm Hg vs.[ 62.4 ± 16.5 ] mm Hg,t =3.414,P ＜ 0.05 ) and lower levels of PaCO2 ( [43.4 ±8.9] mm Hg vs.[50.9 ± 9.1 ] mm Hg,t =5.317,P ＜ 0.05 ) than the control group.There were significant differences in the total effective rate between the Budesonide group and the control group (96.7％ vs.88.3％,x2 =4.218,P ＜ 0.05 ).Conclusion Noninvasive positive pressure ventilation combined with aerosol inhalation of budesonide is a simple and effective strategy for patients with severe asthma.Thus it may be worthy to be widely used clinically.
RESUMO
Objective To explore influence of noninvasive positive pressure ventilation treatment on the brain natriuretic peptide(BNP) level of patients with pulmonary heart disease.Methods 104 patients with pulmonary heart disease were randomly divided into two groups,control group ( conventional therapy) and study groups ( noninvasive ventilation),each group 52 cases.The BNP level of the two groups before and after treatment were detected and compared.Results After treatment,the BNP level in the two groups were all decreased,and the BNP level of the study group was( 197.8 ± 39.6) ng/L,which was significantly lower than that of the control group[ (320.9 ± 43.0 ) ng/L ]( t =3.22,P ＜ 0.05).Conclusion Noninvasive positive pressure ventilation treatment could effectively reduce BNP level in patients with pulmonary heart disease.
