Because the influence of fibrin on the reaction of plasm inogen activation by various plasminogen activators is different, the kinetic co nstant of the reaction of plasminogen activation catalyzed by InB with and witho ut fibrin were detected. The result is: Kfibrinm＝4.2 μmol*L -1，greater than the normal Km=0.379 μmol*L-1; kfib rincat＝0.107 s-1，greater than the normal kcat=0.0165 s-1. The results suggest that existence of fibrin in the reaction system of plasminogen activation depress the affinity between InB and plasminog en, but accelerates the hydrolysis of plasminogen by InB. The count up effect is inhibition.

Objective To study the strategy of expanding standard donor heart application and to analyze the clinical effect on applying expanding standard donor heart in heart transplantation.Methods 146 patients received heart transplantation in Fuwai Hospital Bering from June 2004 to February 2009.Expanding standard donor heart was defined as prolonged ischemic time over 6 h,advanced age up to 40,and blood type ABO mismathched.Blood type examination and PRA test were done before operation.The donor heart was preserved by sequential perfusion with cold St.Thomas and HTK solution.The patients were divided into groups according to different oversize body weight,ischemic time,and donor age Results There were 11 deaths after operation.Ischernic time of donor heart was 262.1±120.8 min,and that of 21 donors was over 360 min(the longest one was 605 min).There was no significant diffeFence in recipient properties before transplantation.and also there was no significant difference in mortality,heart function,heart rejection,and main morbidity after transplantation and during follow-up.Conclusion These data support continued aggressive utilization of expanding standard donor hearts in heart transplantation.Our experience demonstrates thatproperly expanding standard cardiac allografts application has no effects on the short- and long-term clinical outcome following heart transplantation.
