Total RNAs from KAx-3 cells and AK127 cells(developed for 14h) were isolated. After the reverse transcription and PCR reaction, two distinct differential fragments were acquired., fragment A was from KAx-3 cells and fragment C was from AK127 cells. After retriving and reamplifying the differentially expressed fragments, white-blue plaqueselection, the fragments were purified. Northern blot proved that fragment A was from KAx-3 cells and fragment C was from AK127 cells. The results of sequencing and researching for NCBI database have been showed: part sequence of fragment A shows 91% similarity to the gene encoding DhkA, 92% similarity to the gene encoding DhkF, 91% similarity to the gene encoding STATc, 97% similarity to the homoeobox gene encoding protein. These genes play important part in controlling cell differentiation and cell proportion in Dictyostelium discoideum.

本研究通过提取盘基网柄菌发育14小时的野生型KAx-3细胞和突变型AK127细胞的总RNA，运用mRNA差异显示法分离出了两条明显的差异表达片段，其中片段A来自野生型KAX-3细胞，片段C来自突变型Ak127细胞；并通过凝胶回收差异片段、对差异片段进行再次PCR、蓝白斑筛选克隆、提取质粒、酶切电泳纯化差异片段；接着进行Northern杂交的结果表明，片段A只与野生型KAx-3细胞的总RNA有杂交信号，片段C只与突变型AK127细胞的总RNA有杂交信号，这就排除了差异片段假阳性的可能；最后通过测序，搜索NCBI BLAST数据库发现：片段A的小部分序列与编码组氨酸激酶DhkA基因中一段序列的相似性高达91%，与编码组氨酸激酶DhkF基因中的一段序列相似性高达92%，与编码STATc蛋白基因的一段序列相似性达91%，以及与编码同源框蛋白的基因中的一段序列相似性达97%，这些基因在盘基网柄菌细胞分化和细胞比例调控过程中起着相当重要的作用，这些数据进一步说明了突变细胞不能完成发育的原因。

This article surveys and sums up the features of the recent In-migrant crime, analyzing its causes, meanwhile appraising the policy and law and figuring out the nullity in practical resulted in the absence of justice.

本文通过对近年来的苏州市外来人口犯罪的现状特点进行调查和总结，在此基础上对其犯罪的原因进行分析，同时对现行管理外来人口、控制外来人口犯罪的政策法规进行评述，指出其在理论上缺乏正当性从而导致在实践中无法发挥应有的功效。

However, invertors might not understand employee bonus that should be treated as expense in the income statement, rather than as a distribution of earnings in the statement of retained earnings at the beginning. Accordingly, investors did not consider the factor of director compensation and employee bonus in their investment decision-making so that there had been existence of mechanical hypothesis on employee bonus.

但是在未修改法规之前，投资人并未了解员工分红应该列为损益表中的费用，而是认为列在保留盈余中作为盈余之分配，因此投资人在进行投资决策时未能考虑董监酬劳以及员工分红，所以投资人对员工分红会存在机械性假说之状况。

The five prosthetic groups (FAD, [2Fe-2S], [4Fe-4S], [3Fe-4S] and heme group) required for electron transfer from succinate to ubiquinone were unambiguously assigned into the electron density map. Besides, we find there are some electron densities around the Qp pocket at the matrix side and we believe it represents the head structure of ubiquinone, which is proved by the inhibitor bound structure that 2-TTFA just locating at the Qp site. At the same time, we find there is the second 2-TTFA binding site, locating the inter-membrane side. This finding will change our knowledge about the electron transfer inside Complex II and the ubiquinone transfer between Complex II and Complex III, and endow a new role of Complex II in electron transfer chain.

除了对各个电子传递体（ FAD ，[2Fe-2S]，[4Fe-4S]，[3Fe-4S]以及血红素分子）进行精确定位外，我们在该结构跨膜区靠近线粒体基质一端的口袋 Qp 中，发现了一些电子密度，认为是所结合的辅酶 Q 的头部结构，这一点被与抑制剂结合的复合体的结构所证明，在该结构中， 2－ TTFA 恰好结合在口袋 Qp 中，同时，我们还发现了第二个2－ TTFA 的结合位点，位于跨膜区靠近线粒体膜间隙一端的口袋 Qd 中，这个发现具有全新的意义，将影响人们对电子在复合物 II 中传递以及辅酶 Q 在复合物 II 与 III 之间转移的认识，促使人们重新复合物 II 在线粒体呼吸链中的角色。

Part two: Main body, expounds the development of the new period fiction"s introduction from, reference to and fusion with western modernistic fiction, of the breakthrough of the original aesthetic norms and of conducting the "modernity" of the new research of fictional style. The development is as follows: beginning from exploring the artistic forms and skills, it self-examines the history, searches for the meaning of life, and calls for the realization of certain "personality", i.e. spiritual freedom; then, adopts the spirits of modernistic literature, searches for and sublates our national traditional culture; cares for the modern people"s specific mental states and makes inquiries for the meaning of life; then, revolutionizes the textual narration, reveals the doubt about the man"s subject exposed in the theme of works, describes directly the problems of the man"s subject itself, inquires the reality and possibility of the subject"s being, and uncovers the complexity of the modernistic central proposition: man"s anxiety and his essence.
