There had significant difference between the location, the mitosis, Ki-67 expression and the prognosis; but no significant difference between the location, the hemorrhage, cellular necrosis, stroma mucus, CD117 expression and the prognosis. Conclusion The tumor's size, mitosis, and Ki-67 expression are associated with prognosis; CD117 expression and prognosis. Even more, Ki-67 expression may be a more precise factor to judge the tumor's biological behaviour compared to the mitosis. As a wally classified method, the Flecther classification is worth to spread.

AIM: To gain an insight into preference for elderly diabetic patients with angina pectoris between Shexiang Baoxin Pill (SXBXP) (Moschus, Radix Ginseng, Calculus Bovis, etc.) and Extended Release Isosorbide 5-Mononitrate (ERIM). METHODS: Followed a two-week run-in, 56 elderly patients were randomized to take SXBXP 2 pills tid or ERIM 60 mg qd for 4 weeks; then followed a two-week wash-out, patients crossed over to the complementary therapy for another 4 weeks. Daily diary cards were used to record the side effects, the frequency of angina pectoris attacks and use of rescue medication. At the end of the study, participants were asked to complete a 3-item scale questionary to assess their angina pectoris treatment in terms of convenience, side effects and overall preference. RESULTS: No treatment difference in the frequency of angina pectoris attacks and use of rescue medication was found; 71.4% of patients thought use of SXBXP was the same convenient as that of ERIM; patients felt SXBXP had side effects fewer than ERIM and overall 75% of patients preferred SXBXP. CONCLUSION: Elderly diabetic patients with angina pectoris prefer SXBXP to ERIM.

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.
