Objective: To investigate the association of Glu298Asp polymorphism of the eNOS gene with essential hypertension in elderly people.

目的：了解中国老年人群血管内皮型一氧化氮合酶基因Glu298Asp多态性的分布，探讨其与原发性高血压病的关系。

Recent epidemical study indicates that the incidence of AD in some populations is substantially influenced by the gene polymorphisms of the inflammation mediators.

近来流行病学研究显示炎症介质的基因多态性可以影响阿尔茨海默病在人群中的发病率。

The splicing mutation of COL7A1 gene is the underlyi ng cause of and specific rather than common polymorphism for the family with dys trophic epidermolysis bullosa pruriginosa subtype.

结论COL7A1基因剪接位点的突变是引起该家系临床症状的特异突变，而非多态性改变。

The fibrinogen β448 and -455 polymorphisms were reported to be associated with plasma fibrinogen levels and ischemic heart disease.

关于基因多态性和冠心病之间的关系仍有争议，有待进一步的研究。

It was indicated that DNA fingerprinting could reflect genetic material of outbred strain rat,and were more polymorphic.

结果表明，DNA指纹图较好地反映了封闭群动物的遗传本质，具有良好的多态性。

Since this polymorphism is distributed randomly during gamete formation, its association with stroke should not be biased or confounded.

由于这种多态性是在配子形成时随机分布的，所以它与卒中的关联性不应混淆或存在偏见。

It is significant to investigate the frequency, mutation,polymorphism and expression of gene α2M for the pathogenesis of late-onset AD and its genic diagnosis.

研究α2巨球蛋白基因的频率、突变、多态性或表达对晚发型AD的发病机制和基因诊断有重要意义。

The RAPD system of Gladiolus was optimized. Of the 12 random primers analyzed in this research, 9 primers can show steady and polymorphic amplification profiles.

建立了适用于唐菖蒲RAPD分子标记的反应体系，从12条随机引物中筛选出9条可扩增出多态性条带的引物。

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。
