ObjectiveTo determine the effects of Radix Salviae Miltiorrhizae (RSM) on the proliferation of vascular smooth muscle cells(SMC) induced by plateletderived growth factor(PDGF).MethodsRat arterial SMC cultured in vitro were divided into the control group, RSM group (subdivided into 3 concentration groups:2.0mg/ml, 0.4mg/ml and 0.08mg/ml),PDGF group(10ng/ml) and PDGF(10ng/ml) plus RSM (the 3 concentrations the as the same as above) group. The number of SMC and 3HTdR incorporation of SMC were measured. Results PDGF induced the increases of the number of SMC and 3HTdR incorporation of SMC significantly, which were as 3fold and 2.5fold as those of the basic situation respectively. RSM,which was dosedependent, inhibited the increase of the number of SMC and 3HTdR incorporation of SMC in the basic and PDGF stimulated situations . ConclusionsRSM may inhibit SMC proliferation in the basic and PDGF stimulated situations.

Since cardiopulmonary resuscitation(CPR)guidelines was constituted in 1974,it was adopted many times.The American Heart Association,in collaboration with the International Liaison Committee on Resuscitation(ILCOR),adopted new CPR science guidelines in January,2005.This article gives a short introduction of CPR,and showes the progress of several editions.
