The molecular aggregation with various functions in the body is formed through hydrogen bond, electrostatic force, Van der waals force and hydrophobic force between biomacromolecules and small molecules, and between the biomacromolecules.

在生命体系中，核酸、蛋白质和糖类是生物体的三大基本要素，生物大分子间以及生物大分子与在生命过程中起重要作用的有机小分子通过氢键、电荷相互作用、范德华力以及疏水作用等分子间作用力组成各种功能特殊的分子集合体。

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。

It is intimately involved in spindle formation and chromosome segregation during mitosis. Now, the over-expression of PLK1 has been found in various primary carcinomata, and indicated the probability of PLK1 as a new tumor marker.

近年来，研究发现PLK1（polo-like kinase 1）基因在有丝分裂过程中起重要的调节功能，并且在多种的人类肿瘤包括肺癌中发现PLK1基因表达升高，提示PLKl的增长表达在细胞的增殖中起重要作用，预示PLK1可能是一个新的肿瘤标记物。

MMP2 and MMP-9 play an important role in the modulation of thophoblast invasion, and their expression is difference in difference stage of first trimester pregnancy, these provided experiment basement for deeply investigation action of MMPs in the mechanism of cytotrophoblast invasion.

MMP-2和MMP-9在调节滋养细胞浸润过程中起重要作用，且在早孕不同时期，二者表达不同，为深入探讨MMPs在滋养细胞浸润机制中的作用提供理论基础。

PPARγ plays an imporlant role in the modulaltion of thophoblst invasion. PPARγ ligands can inhibit invasion through down-regulating MMP-2 and MMP-9 expressions, these provide experiment basement for deeply investigation of PPARγ ligands in the mechanism of cytotrophoblast invasion.

PPARγ在调节滋养细胞浸润过程中起重要作用，而且其作用可能是通过调节MMP-2和MMP-9的表达实现的，为深入探讨PPARγ及其配体在滋养细胞浸润机制中的作用提供实验基础。

In the present paper, the Sox gene expression analysis of different tissues from the Trionyx sinensis was studied by using RTPCR, and Sox gene fragments of expression from the testicle, brain and spleen were cloned using RTPCR products. The results show that Sox gene has specific expression in the testicle, brain, spleen, cardiac muscle and kindney and hasn't expression in muscle, liver and ovary. The results of clone reveal that the Sox genes of expression in the testicle are TSSox1 and TSSox 4, and those are TSSox2 and TSSox4 in the brain, and that is TSSox4 in the spleen. This suggests that the Sox gene act important role not only on the sex determination, but also on the development of neural system, immunocyte system and the differentiattion of male germ cell.

本文采用RT—PCR技术，研究了中华鳖不同组织Sox基因的表达，并通过PCR直接克隆法，分析了来自睾丸、脑和脾组织中的Sox基因序列结果表明在中华鳖的成体组织中，Sox基因在脑、心肌、肾、脾和雄性的睾丸组织中均有不同程度的表达，而在肌肉、肝脏和雌性的卵巢中则无表达，显示该基因具有组织表达特异性克隆分析显示，在睾丸组织中表达的是TSSox1和TSSox4基因，而在脑组织中表达的是TSSox2和TSSox4基因，脾组织中表达的是TSSox4基因此结果表明Sox基因不仅在性别决定中起作用，还可能在神经系统、免疫系统多种组织中起重要作用

BACKGROUND: The HOX gene family is a highly conserved transcription factor family, which affects the formation of basic axis and secondary axis during embryonic development, at the same time, it plays a pivotal role in the development of the central nervous system, axial skeleton, stomach intestine, urogenital system and external genitalia.

背景：HOX基因家族是一个高度保守的转录因子家族，该家族在胚胎发育阶段基本体轴和次级体轴的形成中起作用，同时在中枢神经系统、中轴骨、胃肠和泌尿生殖系及外生殖器和肢体的发育中起重要作用。
