blood circulation and removing blood stasis. METHODS:The effects of different concentration of 12 active components [caffeic
acid(1.56-200 μmol/L),ferulic acid(1.56-200 μmol/L),senkyunolide H(3.125-200 μmol/L),n-butylidenephthalide(3.125-200
μmol/L),ligustilide(1.56-200 μmol/L),cryptotanshinone(0.625-80 μmol/L),tanshinol sodium(1.56-200 μmol/L),paeoniflorin
(1.56-200 μmol/L),formononetin(1.56-200 μmol/L),salvianolic acid B(1.56-200 μmol/L),catechin(1.56-200 μmol/L)and
astragaloside Ⅳ(1.56-200 μmol/L)] on the proliferation of HUVECs were evaluated by CCK-8 assay. The effects of above active
components(3 dose groups,setting up 0 μmol/L blank control group,hereinafter)on mRNA expression of key proteins JAK2,
STAT3,Akt,ERK in JAK/STAT signal pathway were measured by RT-PCR. The effects of each active component on the
expression of PAI-1,VCAM-1,ICAM-1,VEGF and NF-κB p65 were detected by ELISA. RESULTS:Ferulic acid(6.25,25-200
μg/mL),senkyunolide H(6.25-200 μmol/L),ligustilide(200 μmol/L),cryptotanshinone(10-80 μmol/L),paeoniflorin(1.56,
6.25,12.5 μmol/L),salvianolic acid B(1.56-12.5 μmol/L,200 μmol/L)and catechin(25 μmol/L)could significantly inhibit the
proliferation of HUVECs;caffeic acid (1.56,12.5 μ mol/L),ligustilide (50 μ mol/L),trashinol sodium (6.25 μ mol/L) and
paeoniflorin(1.56,100,200 μmol/L)could significantly promote the proliferation of HUVECs (P<0.05 or P<0.01). Compared
with blank control group,mRNA expression of JAK2,STAT3 and Akt were decreased significantly in some dose groups of ferulic
acid,formononetin,salvianolic acid B and astragaloside Ⅳ(P<0.05 or P<0.01);the expression of PAI-1 were significantly
decreased in some dose groups of caffeic acid,ferulic acid and n-butylphthalide;the expression of ICAM-1 and VCAM-1 were
decreased significantly in some dose groups of caffeic acid,ferulic acid,n-butenylphthalide,cryptotanshinone,formononetin and
catechin;the expression of NF-κ B p65 were decreased significantly in some dose groups of ferulic acid,n-butenylphthalide,
formononetin,salvianolic acid B and astragaloside Ⅳ;the expression of VEGF were increased significantly in some dose groups of
caffeic acid and catechin(P<0.05 or P<0.01). CONCLUSIONS:The active components of Naoxintong capsule may play the role
of promoting blood circulation and removing blood stasis by inhibiting the expression of JAK/STAT signal pathway key protein
mRNA and PAI-1,ICAM-1,VCAM-1,NF-κB p65 in HUVEC,and promoting the expression of VEGF.
