The cells in cross-section of leaf and stem become swollen and intercellular space of the ground tissue increass when the expression of UDPGDH gene was inhibited in tobacco. When UDPGDH gene was over expresed, opposite physiological changes were observed. These results further suggested that UDPGDH gene may play an important role in the synthesis of pectin and hemicelluloses in ramie.

初步的组织学分析表明，反义和干扰表达的转基因植株中，茎段与叶横切面细胞结构较为松散，基本组织细胞间隙增大，而在UDPGDH基因过量表达的转基因植株中则观察到相反的现象，进一步证实UDPGDH基因在苎麻半纤维素和果胶合成中所具有的重要作用。

The yellow boards play an important role in prevention and cure white fly in greenhouse because they can trap, stick and kill white fly. The test also shows that almost white fly often appear in the space where 5cm-15cm upper than the top of the plant. According to this result, the optimal hanging height of the yellow board should be at the place where 5cm-15cm upper than the top of the plant. The yellow boards should be set up as much as possible in this space to reach the best preventative effect.

同时使用黄板诱杀这一物理防治方法，也可有效减少温室内白粉虱数量，并且确定了植物顶端上方5~15cm处是白粉虱较活跃的区域，因此黄板应尽可能多的覆盖这一区域，以达到最好的防治效果。

These findings suggest that both GRβand SRp30c especially the ratio of GRα/GRβplay an important role in the mechanism of the action of GC,and GRβfunction as a dominant negative inhabitor of GRαin there.

以上说明，GR亚型在PBMC中表达的强弱及数量与GC治疗疗效密切相关， GRβ、SRp30c表达越强，含量越高，GRα/GRβ比例越低，则疗效越差。

The positive expression rates of Tissue Inhibitors of Metalloproteinase-2 protein in the cases of involuting groups were significantly higher than those in proliferating group and vascular malformation groups and normal skin group (P.05). Its difference was significant. Conclusions: Matrix MetallProtinase-2 and Tissue Inhibitors of Metalloproteinase-2 may play an important role in the pathogenesis of hemangiomas through angiogenesis. They may have no effect on vascular malformation and normal skin

血管瘤退化期，TIMP-2表达明显升高，说明 TIMP-2与血管瘤纤维化、消退有关，其机制可能是一方面通过抑制MMP-2介导的基底膜降解而在内皮细胞迁移、聚集中起作用，另一方面直接抑制内皮细胞的增殖及迁移，使内皮细胞高频率调亡，细胞外基质增多，组织出现纤维化，最终导致血管瘤的退化。2、血管畸形和正常皮肤小血管中MMP-2和TIMP-2不表达或表达较弱，说明血管畸形和正常皮肤小血管中并不存在异常的血管生成，据此可以对血管性疾病进行分型、分期，并指导临床治疗。

The academic significance and the applied value of research into Yi structural auxiliary words include the following: 1. The structural auxiliary words play an important role in Yi grammar. Many problems in Yi syntax could be solved if the special features of Yi structural auxiliary words were understood. 2. The study of Yi structural auxiliary words may provide a foundation for a theoretical framework of function words and clarify the rules for the development of Tibeto-Burman languages. 3. The study of Yi structural auxiliary words may help in the study of Chinese grammatical history. It can supply some useful clues in the study of Chinese structural auxiliary words and the historical evolution of Chinese grammar.

彝语结构助词研究的学术意义和应用价值在于：1、结构助词在彝语语法中占有重要的地位，认清了彝语的结构助词特点也就解决了彝语句法的大部分问题。2、彝语结构助词的研究有助于建立藏缅语族语言虚词理论框架，弄清藏缅语族语法手段的发展规律。3、彝语结构助词的研究有助于汉语史的研究，可以对汉语结构助词和汉语语法历史演变的研究提供许多有用的线索。4、彝语结构助词的研究还会对彝语文的规范和教学、双语教育、翻译出版等起到有益的作用，具有实际应用的价值。
