Methods: Twenty-four male SD rats were randomly divided into normal control (NC, n=6), protein C activator (PCA, n=6), lipopolysaccharide (LPS, n=6) and LPS+PCA group (n=6). NC group were given normal saline and PCA group were injected protein C activator (0.4 mg/kg) through vein of the tail. LPS group were administered lipopolysaccharide (10 mg/kg, 4h) by intraperitoneal injection method to make the model of septic shock rats. After the animal model was made, LPS+PCA group were injected protein C activator (0.4 mg/kg) through vein of the tail. 30 minutes after the injection, each rat was tested by Medlab biosignal analyzing system for observing mean arterial pressure and left ventricle function, the activity of LDH and iNOS in myocardium and the cuttings of myocardial tissues.

METHODS: Human AMSCs were isolated in vitro sterilely. At the third passage, 0.5 mL single cell suspension at 1×109/L was obtained and transplanted by tail venous pathway in transplantation group mice, Mice in the control group were injected with an equal volume of saline. APP-gene mice in the normal group were left intact. 5'-bromo-2-deoxyuridine labeled third-generation AMSCs expression was detected in mice brain tissue by immunohistochemical method.
