The iso-electric point of was 4.8-5.2. The amino acid analysis indicated that the recombinant protein is non- N-glycosylated.The ability of 0.5 ug/m rhsTRAIL to induce apoptosis of liver cancer cells SMMC7721 and BEL 7402 could be visioned morphologically. This was further verified by Electrical microscope observision of induced SMMC7721 cells and agarose gel electrophoresis of apoptosis DNA. MTT test results also showed that 0.01 u g/ml purified rhsTRAIL has strong effect to induce apoptosis of SMMC7721 cell.

形态学上观察了rhsTRAIL对肝癌细胞SMMC7721和BEL7402的诱导凋亡活性，发现rhsTRAIL在0.5μg/ml时显示了很好的诱导凋亡活性，并通过电镜观察rhsTRAIL诱导后的SMMC7721细胞，证实了凋亡；同时提取凋亡细胞DNA，进行琼脂糖电泳分析，在分子水平证明凋亡；最后利用SMMC7721细胞分组加入纯化后的rhsTRAIL蛋白，结果显示纯化蛋白含量在0.01μg/ml时细胞就呈现了诱导凋亡活性。

The main results are:In logic system r,G r, tautologies can not be get by using upgrade algorithm to non tautologies within finite many times; In logic system S n , tautologies can be get by using upgrade algorithm to an arbitrary formula of F at most n times; Congruence partitions about ...

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.
