Rats with CHF were divided randomly into two groups, one group was injected dexamethasone(1mg /kg) intramuscularly at the first and forth day respectively,the other group was injected equi-volume saline likewise, and observing the changes of symptoms of rats with CHF; measuring rats hemodynamics index including blood pressure, heart rate and left ventricular end-diastolic pressure 4 days later. Part 2: To measure every group rats myocardialα1、β1、β2、β3-AR density by immunohistochemical method ,and to understand the AR density changes .Taking the first part rats'myocardium tissues for testing myocardialα1、β1、β2、β3-AR density and 5 normal rats for normo-contrast group and taking gray scale of slice as AR density. Part 3: The study enrolled 35 patients with DCHF. Patients were included if they had orthopnea and refractory edema due to acute DCHF that was severe and had taken more 1 week hospitalization and intravenous therapy in addition to diuretics.
