In addition, we presume that the role of different MMPs is distinct in various stages of EMs development. The difference of subjects which is resulted by the genetic difference of MMP-1 has the association with the risk of EMs, and the abnormal expression of protein may have relation with the development of EMs; The abnormal expression of MMP-3 has a very important role in the development of EMs; As a protein of endothelial expression, MMP-7 may participate in the development of EMs, endometrial cells with high-expression MMP-7 easily take place ectopic implantation in the blood of menstruate countercurrented and increase the risk of EMs; It is not confirmed in our study that there are the association of MMP-9 with the risk of EMs, but in view of other study, we will further evaluate the role of MMP-9 in the development of EMs.

且推测不同的MMPs基因在子宫内膜异位症发生和发展的不同阶段作用不同，MMP-1基因的遗传差异所导致的个体差异与子宫内膜异位症发病风险的个体差异相关，其蛋白的异常表达还可能与子宫内膜异位症的进展相关；MMP-3基因的异常表达在子宫内膜异位症的发展中起重要作用；MMP-7作为一个上皮性表达的蛋白，可能对子宫内膜异位症的发生起重要作用，带有MMP-7高表达的在位子宫内膜细胞更易在经血逆流中"异位"种植，增加个体子宫内膜异位症的发病风险；MMP-9虽然在本研究中没有被证实与子宫内膜异位症的发生和发展有相关性，但鉴于其它相关研究，有待于从其它方法证实MMP-9在子宫内膜异位症进展中的作用。

Result: Immunohistochemic results indicate that after HBO treatment, the expression of CytC and Bax in the neuronal cytoplasm decline significantly ( P.05) except in the time of 72 hours after TBI; the Bcl-2 expression is up-regulated significantly(p.05) after TBI. The images of electromicroscope indicate that before 24hr after TBI, mitochondria of control groups become more swoln even fracted and the matrixes become vaguer than those of being treated with HBO.

To understand whether the GST can protect plant from the damage of ultra-violet radiation,a UV inducible GST gene was isolated from an Arabidopsis cDNA library.The plant expression vector containing the GST cDNA was constructed and transferred into Arabidopsis thaliana plants by the Agrobacterium-mediated vacuum method.Molecular genetic analyses showed that the overexpression of the UV inducible GST could increase the tolerance of the transgenic plants to UV radiation

为了阐明GST在紫外辐射下是否对植物有保护作用，以紫外强烈诱导表达的GST cDNA为探针，筛选拟南芥cDNA文库，获得了这种GST的全长cDNA；利用此cDNA构建植物表达载体，并通过农杆菌介导法转化拟南芥，使其在拟南芥中得到大量表达；通过对转基因植株的紫外辐射耐性分析，证实了该GST的过量表达可明显增强拟南芥对紫外辐射损伤作用的耐受性。

Observation with transmission electron microscope showed that interalveolar septa were widened with increased amount of collagen in the MP infected rats while there were no obvious abnormalities in the other two groups.(2) Positive expression of bFGF mRNA were found in alveolar walls of MP infected rats. No expression of bFGF mRNA was found in control animals. In the rats infected with MP but treated with erythromycin positive expression of bFGF mRNA was found to be scarcely distributed in alveolar walls.

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.
