Results ① The percentage of positive TPOAb and TGAb were 91.4% and 74.4%, respectively in all the AIT patients. 47.6% of the patients had TSH levels within normal range (0.3～5mu/L).② All of the slides had different grades of lymphocytic infiltration. 49.3% had germinal center, 32.8% had Askanazy cells, 26.9% had plasma cells, 22.4% had colloid, and 9% had multinuclear giant cells.③ Lymphocytic infiltration was divided into four degrees. The levels of TSH and TPOAb increased significantly in the extremely heavy lymphocytic infiltration grade than in the others (P.05). There was no relationship between serologic markers and other cytopathologic features.

结果 ①82例患者中TPOAb、TGAb的阳性率分别为91.4%和74.4%，约有半数(47.6%)TSH值位于正常值范围内(0.3～5mu/L)；②所有患者细胞病理学均存在淋巴细胞不同程度的浸润，49.3%可见生发中心，32.8%可见嗜酸性变细胞，26.9%可见浆细胞，22.4%可见胶质，9%可见多核巨细胞；③将淋巴细胞浸润程度分级，分别与TSH、TPOAb及TGAb进行相关性分析，发现仅淋巴细胞极重度浸润者其血清TSH、TPOAb水平较其他组显著升高(P.05)，其他细胞病理学改变与血清学指标之间未发现显著相关性。

mitochondrial dnais the only inheritant substance except for the nuclear dna in a euˉkaryon cell,which is related to the oxidative phosphorylation of a cell.mitochondrial dna is the important target of carcinogens and is vulnerable because of its structure and function.the mutation of mtdna could reduce the nomal respitation and release large quantities of ros,whichincrease the danger of cancer happening.so,mtdna has been thought to be involved in carcinogenesis and recently more and more studies in this aspect have comeout.in this paˉper,we review the researches for relationship among mtdna mutation and tumors in digestion system,woman system,head and neck,urinary systemand blood system.

线粒体dna（mitochondrial dna，mt dna）是真核细胞中唯一存在的独立于核dna之外的遗传物质，与细胞的氧化磷酸化功能密切相关。mtdna自身的结构和功能特点决定了它是致癌物作用的重要靶点，易受致癌因素的损伤而发生突变。mtdna的突变可削弱正常的呼吸功能，释放高水平的活性氧，进而增加肿瘤发生的危险性，所以mtdna被认为与肿瘤发生有密切关系。近年来，这方面的研究越来越多，本文现就mtdna突变与消化系统肿瘤、妇科肿瘤、头颈部肿瘤、泌尿系统肿瘤等实体瘤以及血液系统恶性肿瘤之间的关系作一简单的综述。

Results:The tumor was divided into two histologic subtypes:biphasic type(4 cases) and monophasic type(1 case).

结果 ：组织学检查分为双相性SRCC 4例，由癌和肉瘤样成分组成；单相性 1例，由差分化的肉瘤样梭形细胞、单核细胞与破骨细胞样多核巨细胞组成。

Following fertilization the emdosperm becomes and remains multinucleate for some time, becoming cellular near the time of pit-hardening

受精以后，胚乳变成多核，并继续存在一个时期，近硬核期时变成细胞状。营火的余烬。

The results showed that pendimethalin is a herbicide interfering cell division,The mito-sis of pendimethalin treated root was arrested at metaphase with contracted and condensed chromo-somes and produced a series of abnormal,polymorphic cells such as multinucleate,multinucleolus,micronucleus and polyploid cells.

结果表明，除草通是一种影响细胞有丝分裂的除草剂，其作用方式在于阻止分生组织细胞从前期向中、后、末期的过渡，引起染色体凝集、短缩以及多核、多核仁等一系列畸形与异常变化。

Myoblast differentiation and fusion in multinucleated muscle cells was studied in myoblasts growth in culture. The content ofcalpastatin in muscle wonld be related to cell membrane fusion.

在成肌细胞培养中，成肌细胞融合并分化形成多核肌细胞，其中钙激活酶抑制蛋白的含量与细胞膜的融合相关。

Results of the experimental groups: Comparison with the control groups, in 6h and 8h groups eminences of ependymal cells with cobblestone-like appearance were seen, their microvilli were further richer, and a number of microholes could be found on their base. In body part of SFO cell membrane of some ependymal cells were broken completely, their cytoplasm was no longer seen, and cell nucleus located at one side of the cell, 5-7μm in diameter and dividing lobe-like in shape. Beside those cells some ependymal cells appeared many folds on the top of surface. In 2h and 16h groups the observation results seemed no significant differences from the corresponding control groups.

实验组结果：与对照组相比，在6小时和8小时实验组中，可见成团的鹅卵石状室管细胞隆起于表面，微绒毛更为丰富，微绒毛根部可见到若干微细小孔，在SFO体部的一些室管膜细胞的胞膜完全破裂，胞质几乎荡然无存，仅剩胞核居于细胞的一侧，直径有5.7μm，呈分裂叶状；与这些细胞邻近的室管膜细胞表面最高处多呈现皱襞。2小时与16小时的实验组的观察结果与对照组相比未发现明显差异。

Cell polarity is the fundamental characteristics of eukaryotic cells and of crucial importance to the differentiation and functions of most cells in the metazoans.

细胞极性是真核生物的基本特征。在多细胞动物中，细胞极性在大多数细胞的分化和功能发挥中具有至关重要的作用。

Four weeks later, in the baicalin group, some spindle-shaped UCB-MSCs began to present shrinkage, with slender processes on the cell edge, and some UCB-MSCs tended to be spherical-, conical-, and triangle-shaped appearance, with many slender processes on the pseudopodia.

细胞形态学观察：脐血单个核细胞培养第2~3天开始贴壁生长，2周左右达高峰，3周后细胞生长达80%~90%融合，此时脐血原始间充质干细胞呈较均一的长梭形。4周后，黄芩苷组原来呈梭形的胞体一部分发生收缩，细胞边缘出现细的突起；一部分胞体逐渐近似圆形、锥形、三角形，伪足有多个细长突起。

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。
