OBJECTIVETo observe the different effects of Puerarin and Daidzein on the expression of proliferating vascular smooth muscle cells, and to discuss the mechanism.

METHODMT was used to detect the state of VSMC (vascular smooth muscle cell) activity. The expression levels of Survivin, Bcl-xl, Bax and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) messenger RNA (mRNA) were analyzed quantitatively by reverse transcriptase polymerase chain reaction (Rt-PCR).

RESULTCompared with Puerarin groups, VSMC activity in daidzein groups was lower, and the ratio of Bax/Gapdh/Bcl-xl/Gapdh was higher.

CONCLUSIONThe inhibition effect of daidzein on VSMC proliferation is stronger than that of puerarin.
