(1) cerebral ischemical reperfusion injury rats'limbs motor function is variable. Acupuncture could promote lims'functional recovery.(2) PCNA masc cells is visible in cerebral ischemical semidarkness region. There is cell regeneration phenomenon. Acupuncture could strengthen injury region's PCNA expression, could profit injury recovery and functional reconstruction.(3) In ischemia semidarkness region for the model group and acupuncture group, PCNA masc cells percentage of 14days group is lower than 7days group. Along with the recovery of injury, cell multiplication is weaken.(4) In cerebral ischemia semidarkness region, there is VEGF masc cells and regeneration phenomenon. Acupuncture could strengthen injury region's VEGF expression, could profit protection after injury and blood vessel regenerate.(5) In ischemia semidarkness region for the model group and acupuncture group, VEGF masc cells percentage of 14days group is lower than 7days group. Along with the recovery of semidarkness region, ischemia and anoxemia state is getting improved, and VEGF is reduce.(6) As there are PCNA and VEGF masc cells in brain injured region, we could conclude that, after brain ischemical reperfusion injury, there are blood vessel regeneration phenomenon. Acupuncture could promote blood vessel regeneration, recovery blood supply sufficiently and quickly, and promote the recovery of brain injury region.(7)The VEGF masc cells percentage of inhibitor group is lower than acupuncture group. It state that the effect of acupuncture promote VEGF is partly depend on the existing of eNOS.

实验结论：(1)脑缺血再灌注损伤后大鼠的肢体运动功能发生改变，针刺可以促进肢体功能恢复；(2)脑缺损伤区可见PCNA阳性细胞，存在细胞再生现象，针刺可以增强损伤区PCNA的表达，有利于损伤的修复和功能重建；(3)针刺组和模型组14d时缺血损伤区PCNA阳性细胞百分比低于7d组，随着损伤逐渐得到修复，细胞增殖现象减弱；(4)脑缺血损伤区可见VEGF阳性细胞，存在内皮型细胞再生现象，针刺可以增强损伤区VEGF的表达，有利于脑损伤后保护和缺血区血管再生；(5)针刺组和模型组14d时缺血损伤区VEGF阳性细胞百分比低于7d组，随着缺血损伤的修复，缺血缺氧状态得到改善，产生的VEGF减少；(6)由于脑损伤区同时出现PCNA阳性细胞和VEGF阳性细胞，前者是增殖细胞的标志，后者是促进血管再生的重要因子，可以推断，脑缺血再灌注损伤后脑内存在血管再生现象，针刺可以促进损伤区的血管再生，更迅速而充分的恢复损伤区的血供，促进脑损伤区的修复；(7)抑制剂针刺组脑损伤区VEGF阳性细胞百分比与针刺组相比有不同程度的降低，说明针刺促进缺血损伤区VEGF表达部分依赖eNOS的存在。

Objective To study the relationship of endangium proliferation and the expression of metalloproteinases and tissue inhibitors of metalloproteinases after angioplasty of iliac artery in rabbits to investigate the probable mechanism of composite Danshen pill in prevention and treatment of restenosisMethods 30 white male rabbits of Japan （the average body weight was 25～30 kg）were randomly divided into 3 groups:normal control group,model group (intima destroyed by balloon and given hypercholesterol diet),CDP group (intima destroyed by balloon and given hypercholesterol diet plus drug CDP 150 mg/d),10 ones each groupResults The results of iliac artery angiogram and the analysis of pathology:there were lumens stenosis,thinner intima,smaller intima area,in CDP group compared with those in model group,and ratio of intima and tunica media thickness and area among each group (P＜001)Immunohistochemistry analysis:the MMP2,MMP9,TIMP1,TIMP2 in model group significantly increased than those in control group (P＜001)The CDP group had lower MMP2 and MMP9 expression,higher TIMP1 and TIMP2 expression,and increased MMP2/TIMP1,MMP9/TIMP2 than model group (P＜001)The thickening of vascular neointima and stenosis degree of vascular lumen were relevant to MMP2 and MMP9 (r=0896,P＜001)Conclusions MMP and TIMP play the very important role in the restenosis process of arteryCDP could inhibit the thickness of vascular neointima after balloon injury,the probable mechanism of which may be inhibiting collagen formation,smooth muscle immigration and decreasing hyperplasia of intima by interfering expression of MMPs and TIMPs
