When they are released into the extracellular environment, or when they are membrane-bound and in contact with the pericellular zone, these enzymes degrade a broad range of connective tissue proteins and are important during the development of healthy tissue as well as in remodeling damaged tissue.

当它们被释放入细胞外环境，或者是与膜结合后与细胞外环境保持接触时，这些酶能够使大范围面积的结缔组织蛋白酶降级，这样对健康组织的发育以及对受损组织的重塑相当重要。

The expression of AT2R gene can be regulated efficiently in vivo by local delivery of MSC with dual-stable expression of AT2R gene, thus reduces the formation of intimal hyperplasia.④AT2R gene can influence the expression of ECM and significantly promote the cellular apoptosis in the injury rat carotid artery.⑤These data demonstrate the clinical potential of AT2R regulatable expression to prevent restenosis after PCI.

研究结论：(1)与VSMC直接接触可以诱导MSC向血管成分细胞分化；(2)构建的Dox-on可调控的MSC细胞株诱导活性可靠，使外源AT2R基因的表达处于有效的主动控制下；(3)局部导入MSC不影响球囊损伤后大鼠颈动脉新生内膜增生；(4)由MSC介导的AT2R可调控表达受到Dox的良好调控，可有效抑制球囊损伤后大鼠颈动脉新生内膜增生；(5)AT2R影响血管损伤后修复时ECM成分的表达，并促进细胞凋亡的发生，可能是AT2R介导抑制新生内膜形成的机制。

In a word, the greening of residential area should take advantage of the plants' purify, beautification and protective function, making people's daily life every detail and greening in close contact with each other,let residental area is no longer drab, but a complete green ecological system, various kinds of color is the plant, flowering plants, shade plants to create landscape, it is pleasant to create a harmonious natural inhabitants of ecological living space.

总之，居住区绿化要充分发挥植物的净化、美化及防护功能，使人们日常生活中每一细节与绿化密切接触，让居住区绿化不再是一两块单调的绿地，而是一个完整的绿地生态系统，是用各类色叶植物、开花植物、遮阴植物等营造出的怡人景观，是为居民创造的一个和谐自然的生态居住空间。

24 New Zealand white rabbits were divided into control group,Saline group and Mailuoning group,on the latter two groups the models of Hemifacial spasm were made by the temporal superficial artery closely contacting the main trunk of facial nerve at stylomastoid foramen.From the 5th week,the Saline and Mailuoning were injected intravenously into ear margin for 2 weeks on Saline and Mailuoning group respectively.At the 7th week,the MDA and SOD in serum were measured,meawhile the microstructure and ultrastructure of facial nerve were observed on 3 animal groups.

NodD binds to and bends target promoters through anchoring two tandem and individual specific DNA sites. NodD functions as a tetramer, which has a V-shaped main body. Tetrameric NodD is to change its own conformation rather than its oligomeric forms in response to small signal molecules. The specific interaction between each NodD DNA-binding domain and each specific DNA site does not alter itself in spite of naringenin induction, and the induced conformational change is transferred from protein to DNA. Only the DNA conformation incited by induced NodD is competent for RNA polymerase to form the transcriptional open complex. It cannot be excluded that NodD may have protein-to-protein contacts with RNA polymerase, and that the NodD conformational change may also directly contribute to the transcriptional open complex formation. However, the NodD conformational change itself cannot serve as the determinant of the transcriptional molecular switch.

通过研究，我们提出了初步的NodD操纵子激活模型：第一，四聚体是NodD蛋白的功能单位，它通过铆钉两个串联的相对独立的DNA靶位点结合被诱导的启动子；第二，小分子配基的结合是改变NodD四聚体的构象而不是引发不同形式的寡聚体，在我们的模型中，NodD四聚体缩小其V形主体的弯折角，进而缩短其DNA结合功能域的间距；第三，小分子信号的诱导并没有改变NodD的DNA结合域和其DNA靶位点的相互作用，NodD的构象改变由蛋白质经其双铆钉位点传递给DNA；第四，只有诱导状态的NodD激发的DNA构象才能有效地使RNA聚合酶形成转录开放复合物；第五，不排除NodD与RNA聚合酶可能有直接的相互接触位点，不排除NodD构象的改变可能直接有利于RNA聚合酶形成转录开放复合物，但是我们认为NodD构象改变本身不是充当转录激活开关的决定因素。
