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

目的 研究兔髂动脉成形术后血管内膜增生和基质金属蛋白酶及其抑制物表达之间的关系，探讨复方丹参滴丸预防再狭窄的可能机制。方法健康成年二级雄性日本大耳白兔30只，平均体重25～30 kg。随机分为3组：正常对照组10只，模型组10只（球囊内膜剥脱加高胆固醇饮食），治疗组10只（球囊内膜剥脱加高胆固醇饮食以及复方丹参滴丸150 mg/d）。结果兔髂动脉造影、血管病理图像分析检测结果：①复方丹参滴丸组较模型组血管造影示管腔直径狭窄、内膜厚度减少、内膜面积减少、内膜厚度和中膜厚度比、面积比，各组之间有显著性差异(P＜001)。②免疫组化分析：模型组MMP2、MMP9、TIMP1、TIMP2表达均高于对照组（P＜001）；复方丹参滴丸组MMP2、MMP9的表达低于模型组，而TIMP1、TIMP2的表达高于模型组；TIMP1/MMP2、TIMP2/MMP9明显增加，差异有显著性（P＜001）。③内膜的增生以及管腔的狭窄程度与MMP2、MMP9有很好的相关性(r=0896，P＜001)。结论 MMP和TIMP在再狭窄形成中起重要作用；复方丹参滴丸能够明显抑制血管损伤后的内膜增生，可能的机制是通过影响金属蛋白酶MMP2、MMP9及其抑制物TIMP1、TIMP2的表达从而抑制胶原的生成、平滑肌的迁移、增生，而减少内膜的增生。

There were no nick infection, chorioamnionitis and other complications. Eight/sixteen fetal lambs were undergone intro-utero cardiac intervention. The values of body weight and Hct of lambs which were executed. pre-term and full-term delived were (1.77±0.14) kg vs.(2.15±0.23) kg vs.(2.41±0.19) kg and 29%-33% vs. 27%-35% vs. 37%-41%. In autopsy, hydropericardium was found in 4/8 with 1-2.5 mL and 1/8 with 5 mL. Besides 1/8 with interventricular septum centesis injury, there was no centesis damage to endocardium, valve, chordae tendineae, papillary muscles and aortic tunica intima.

病理解剖发现施行手术的8例胎羊/新生羊胸壁穿刺点均位于左侧心前区，心脏进针部位在左室心前区近心尖部位6例，近流出道1例，近室间隔1例；4只少量心包积液(1~2.5 mL)，1只心包积液5 mL，3只未发现心包积液；除1只胎羊有室间隔穿刺伤外，其余胎羊心内膜、瓣膜、腱索、乳头肌及主动内膜均未发现损伤；未发现肺、肝等胸腹腔脏器穿刺损伤；均未发现心包、胸腔感染迹象。

The tunica intima is made of only endothelium,no subendothelial layer.

结果 大鼠冠脉与人心冠脉管壁结构变化有明显不同。

In rat,no matter the young or old,there is only endotheliumin the tunica intima,there are no subendothelial layer and internal elastic membranes.

而在大鼠冠脉不论幼年或老年，其内膜仅由内皮构成，无内弹性膜和内皮下层，因而从幼年至老年始终没有内膜增厚和管腔变窄现象。

Results It was found that the thickness of topical tunica intima of aortas increased in diabetic rats. In each focus, the elastic lamina existed asymmetric thickness and some had fissures and abruptions. The SMCs in superficial lamella showed slight proliferation and disorganized arrangement.

摘要背景：球囊扩张及支架置入后再狭窄、管腔丢失等问题制约了支架置入治疗的进一步发展，血管内膜增殖和凋亡在再狭窄中的作用及干预方法尚在积极探索中。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
