Aim To observe the effect of a treatment proposal named “Golden Triangle” ( Atorvastatin, Tongxinluo,and Aspirin) on the vasa vasorum angio-genesis of early atherosclerosis lesions in rabbits carotid artery. Method Seventy-two healthy New Zealand rabbits with half males and half females were divided into 6 groups randomly ( n =12 ):control group, model group, Tongxinluo group ( TXL ) , atorvastatin group ( ATO ) , aspirin group ( ASP ) , golden triangle group ( ATS) . The control group was fed with common feed-stuff, and all the other groups′ right carotid arteries were equipped with the silicone tube,and were then fed with fatty feedstuff. The Tongxinluo group, the Atorvas-tatin group and the Aspirin group were given suspen-sion of Tongxinluo supermicro powder(0. 3 g·kg-1 · d-1 ) , Atorvastatin ( 2. 5 mg · kg-1 · d-1 ) and Aspirin (12 mg·kg-1·d-1),the golden triangle group were given suspension of Tongxinluo supermicropowder (0. 3g·kg-1 ·d-1),atorvastatin(2. 5 mg·kg-1 · d-1 ) and Aspirin ( 12 mg · kg-1 · d-1 ) . All the groups were fed with medicine for 4 weeks. Tissue slice of carotid artery was stained with HE and observed un-der light microscope. The change of blood liquid was detected by biochemical assay. Immunohistochemical staining was used to detect the protein expression of CD34 around the carotid artery adventitia. Color micro-sphere method was used to detect the blood flow vol-ume change of the cartoid artery microvascular. VEFG, VEGFR-2 gene and protein expression in the cartoid artery were detected by Real-time PCR and Western Blot. Result Compared with the control group,the content of VEGF, VEGFR-2 gene and pro-tein expression and the microvascular blood flow vol-ume of cartoid artery microvascular in the model were significantly increased ( P <0. 01 ) . But those in each drug group were lighter than those in the model group (P<0. 01,P <0. 05). In the ATS group,the content of VEGF, VEGFR-2 gene and protein expression and the microvascular blood flow volume of cartoid artery microvascular were lower than those in the TXL, ATO and ASP group ( P <0. 01 , P <0. 05 ) . Compared with the ASP group,the content of VEGFR-2 protein expres-sion was significantly decreased(P<0. 01)in the TXL and ATO group. VEGF,VEGFR-2 gene and protein ex-pression in different subgroups showed no significant difference( P >0. 05 ) . The content of CD34 was de-creased in TongxinLuo group,atorvastatin group,aspirin group and ATS group. Conclusion The ATS project can reduce the expression of VEGF,VEGFR-2, inhibit the vasa vasorum angiogenesis and decrease proinflam-matory substances in the tunica media and intima of vascular wall. It plays an important role in intervening in the process of AS.
