Then we transfected transitorily the recombinant of green fluorescent protein gene and middle molecular weight neurofilament cDNA into wide type N2a (N2a/wt) and N2a/tau40 to observe the effect of tau accumulation on GFP-NFM fusion protein transport in cellular processes in living cells. At last we used an apoptotic inducer, camptothecin (an inhibitor of topoisomerase-1) to treat N2a/wt and N2a/tau40 cell lines, and compared their apoptotic response.

主要结果如下：一、tau蛋白过度表达和聚积对细胞形态的影响：倒置显微镜下观察两种细胞的形态，发现N2a/wt细胞的突起多而长，而N2a/tau40细胞胞体变圆，突起明显缩短；免疫印迹结果显示转染了tau40的细胞内tau的免疫反应约增加14倍，免疫荧光结果显示N2a/tau40细胞胞体内呈现出较强的红色荧光，tau主要分布在核周和突起起始部分的胞质内，而N2a/wt细胞内的荧光很弱。

Governments or officials are able to infringe or unfairly protect social human rights relying on power, it is the producer of human rights conflict between officials and citizens and inducer of mutual infringement of human rights leading to social conflicts; if social human rights are unintegrated, it is another kind of antagonism or conflict.

因为，政府或官员对社会人权可以依仗权力侵犯和不公正地维护，这就是制造官民人权冲突者，再是造成社会成员之间侵犯人权而致社会冲突叠起者，如社会人权不融合就是对抗或冲突；因此，社会各种矛盾或刑事犯罪会叠起，而随之反抗或冲突也会叠起，而终会造成害人人。

Acetoin was shown to function as an inducer for the expression of aco genes, whereas glucose exhibited a repression effect.

It was found that the asymmetric induction level of H〓-MAP was exclusively higher than that of corresponding MAP. Under the optimized reaction conditions, the allylation product could be obtained in up to 90.9% ee with H〓-MAP having 3, 5-xylyls as chiral inducer.

发现H〓-MAPs比MAPs类配体取得了更好的不对称诱导效果，在优化的反应条件下，可以得到90.9％ee值的产物，大大高于文献中报道的MAPs配体的最好结果（73％ee）。

DCs acquired by our reformed methods express both CD83 and CD 14 molecules highly, and have a higher density than other domestic reports. The higher TNF in DCs culture medium of HC patient suggests DCs in patient still have antigen presenting ability and by optimization the culture medium would improve its presenting ability and have a potential value in design and application individual vaccine. Although antigens pulsed DCs have a decrescent antigen presenting ability but BCG HSP70 could induce its mature and improve its presenting ability. Suggests BCG HSP70 would be a useful mature inducer. Lymphocytes primed by DCs based HC vaccine have the specific cytotoxicity against HCC lines. The CTL after freezing and anabiotic could prophylaxis and therapy HC xenograft on nude mouse. The results also suggests that CD4〓 lymphocytes play a important role in HC with a good differentiation and would be useful in treatment this kind of HC. After being activated by Peptide LLNQHACAV of hAFP and apoptotic HCCs pulsed DCs respectively, the culture medium of activated lymphocytes both contains a high level Th1 cytokines IL-12 and TNF. Primed lymphocytes appeared a characteristic of NK cells. DCs not only inhibited the growth of human HCC and other cancer cells in vitro but also prevented the growth of HC xenograft on nude mouse in vivo. There are at least three kinds of mechanism playing important role in DC based vaccine ,there are inhibition of DCs, HC specific CTL and cytokines pathway.

诱导出的DC共同表达CD83和CD14分子，CD83分子表达明显高于国内报道；肝癌患者DC培养上清中TNF水平高于健康人，提示肝癌患者DC仍具一定的抗原呈递能力，适当调控可使其行使APC功能，以期在肝癌个体化疫苗中发挥作用；DC负载肝癌可溶性抗原后，抗原呈递能力降低，BCG HSP70可促进DC成熟，增加其抗原呈递能力，预示BCG HSP70有可能成为促进DC活化和成熟的另一重要分子；肝癌DC疫苗在体外诱导肝癌特异性淋巴细胞，活化的淋巴细胞在体外对肝癌细胞的杀伤以特异性CTL为主，同时分泌较高水平Th1型细胞因子IL-12和TNF，并抑制4种肝癌细胞生长；冷冻复苏后的肝癌特异性淋巴细胞可以预防和抑制人肝癌裸鼠皮下移植瘤，提示DC负载肝癌可溶性抗原后诱发的MHC-Ⅱ类限制性CD4〓T细胞有可能在分化程度高的肝癌治疗中发挥作用；用DC和HLA-A2〓DC分别负载凋亡肝癌细胞和hAFP218-226位LLNQHACAV HLA-A2限制性九肽，在体外诱导肝癌特异性淋巴细胞，活化后的CTL细胞分泌较高水平的Th1型细胞因子IL-12和TNF，并具较强杀伤活性，此CTL同时具备NK细胞特征；DC对肿瘤细胞的抑制作用可能是通过吞噬实现的，Fas-L在DC抑制中也起一定作用；DC对人肝癌裸鼠皮下移植瘤的抑制率为97％；在肝癌DC疫苗的作用中，至少联合3种以上机制，即通过DC的直接作用、肝癌特异性CTL和细胞因子途径直接或间接地杀伤和抑制肝癌细胞。

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。
