Methods:The subcutaneous adipose tissue was obtained from the fold inguen of four SD rats, then digested with collagenase type Ⅰ and cultured in endothelial medium for seven days.

获取4只雄性SD大鼠鼠蹊部皮下脂肪，通过机械分割和组织消化法获取脂肪基质细胞，在内皮细胞培养液中培养7d后，经免疫细胞化学及透射电镜鉴定证实95%以上细胞已具内皮细胞表型特征，再将这些细胞进行成脂(DMEM/F-12培养基内加入0.5mmol/L1-甲基-3-异丁基-黄嘌呤，1μmol/L地塞米松，10μmol/L胰岛素，200μmol/L吲哚美星)定向诱导7d，形态学观察和油红O特殊染色鉴定诱导后的细胞。

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.
