RESUMEN
Objective To contrast and observe the bone marrow stem mobilization induced by Yiqi Wenyang Huoxuefang and G-CSF,and the influence to left ventricle reconstruction. Methods Model rat was made by ligate LAD,quantity of circulation stem cells(CSC) at the first,fifth and tenth day was detected. After be treated 8 weeks,the heart index,the expansion index and the thinning ratio were calculated. Results The quantity of CSC of Chinese herbs group increased at the fifth day(P
RESUMEN
Objective The trial was designed to observe the hemodynamic circadian rhythm in serious heart failure.Methods Totally 140 cases were assigned into the trial;120 cases of serious heart failure were into the heart failure group and 20 cases without heart failure into the control group.Heart rate(HR) and stroke volume(SV)were measured per hour during hospitalization.Results Circadian rhythm existed in two groups,but the heart rates were faster and the stroke stroke volumes lower in the heart failure group.As a whole,the HR and SV were positively correlative in two groups.But the cures of heart rate and stroke volume were separate between 1:00~4:00 before dawn in the heart failure group.The heart rate descended,while stroke volume rose.Conclusion There is divergence phenomenon between heart rate and stroke volume before dawn in serious heart failure.
