DATA SYNTHESIS: Diabetes had been seriously threatening human health, and islet cell transplantation was a possible method that could cure the diabetes, however there was not enough islet resource so that people started to look for other vicariousness resource of islet cells.

资料综合：糖尿病是严重威胁人类健康的疾病之一，胰岛细胞移植是治愈糖尿病的可能方法，但由于胰岛细胞数量有限，不能满足临床需要，人们开始寻找胰岛细胞的可替代资源。

Abjective We detected the quantity and ability of CD4+T and CD8+ T cells in peripheral blood and liver tissues ,and investigated the change of cytokines in the liver to study the probably mechanism about HBV affect cellular immunity system in human body.

目的 通过检测乙型肝炎病毒感染后外周血及感染肝组织内CD4+T和CD8+T细胞的数量及功能，以及检测HBV感染者肝组织内细胞因子TNF-α及TGF-β2表达的变化，探讨HBV对人体T细胞免疫的影响及其可能机制。

BACKGROUND: The study on regulation adipogenic differentiation of adipose tissue-derived stromal cells is benefit for artificial control differentiation direction of adipose stromal cells, and promote further understanding of cell differentiation.

The two cells that produced by the amicronucleate cell were still without micronucleus.

在整个接合过程中，无小核细胞的大核始终没有发生可观察到的形态学变化，它最终分裂成的二个子细胞仍为无小核细胞。

The object of this study is to evaluate the immunoregulation and anti-tumor activities of Arnebia root polysaccharide in vitro. The ARPS was obtained by hot-water extraction, alcohol precipitation, de-protein, de-color, and dialysis etc. from Arnebia root and was administered on mouse spleen lymphocyte and tumor cell with 24 μgmL^(-1), 121 μgmL^(-1), 364 μgmL^(-1), respectively.

为研究紫草多糖在体外对小鼠脾淋巴细胞的免疫调节活性及对肿瘤细胞的细胞毒作用，本实验采用水提醇沉法，经脱蛋白、脱色、透析等方法提取紫草多糖，MTT法检测紫草多糖对淋巴细胞增殖及对HepG2、SPC-A-1肿瘤细胞的杀伤作用。

In addition, the recent evidence showed that nestin could be expressed in reactive astroglia, myoblast and some kinds of tumor cells, suggesting that nestin may have more extensive biological meanings.

SVZ背外侧角和外侧壁的BrdU阳性细胞数和BrdU标记率均随增龄而显著下降，齿状回颗粒下层的BrdU阳性细胞数亦随增龄而显著下降，提示脑衰老可能与神经前体细胞的增殖代偿能力下降有关。

The ultrastructure characters of pollen grain in Brassica napus are:1There are vacuoles in cytoplasm but no starch grain in uniceelluar pollengrain.2The veget- ative nucleus of bicellular pollen grain is generally spheroidal;while the generative cell is spinde-shaped,with a big nucleus,thin layer of cytoplasmand few cell orgens,no cell wall.3In three-celled pollen grain the sperm cell is separated from the cytoplasm of vegetative cell by two layers of plasmic membrances.

Brassica napus的花粉粒，在不同发育时期超微结构的特征如下：1单胞花粉粒有一个球形的细胞核和明显的核仁，细胞质内出现液泡，缺少典型的淀粉粒。2双胞花粉粒的营养核多为球形。生殖细胞纺锤形，无细胞壁，细胞核比例大，细胞质呈薄层，细胞器少。3三胞花粉粒有一个裂片状的营养核和两个纺锤形的精细胞，精细胞无壁，以两层质膜与营养细胞的细胞质相隔。

The ratio of cell perimeters to areas of bulliform cells only reached 0.723 of epidermal cells, which was an important quantitative characteristic to achieve function of bulliform cells.

为深入研究小麦叶片泡状细胞的功能与细胞微观形态数量特征的关系，利用显微摄影及图像分析系统对小麦叶片表皮泡状细胞形态的数量特征进行了统计分析。

Centrins play a fundamental role in centrosome duplication and contraction of centrin-based fiber systems in eukaryotic cells.

中心蛋白是真核细胞中一种重要的蛋白质，与细胞中纤维的收缩、细胞的分裂等密切相关。

Thunberg Fritillary Bulb is one of the most popular Traditional Chinese herbs. Some trials in vivo and animals indicated that Peimine and Peiminine, extracted from Thunbery Fritillary Bulb, have the function of reversing MDR of two different kinds of mechanisms. They can improve the cytotoxic of ADR to cancer cells by 5～10 folds under concentration of 10% cancer cell growth inhibitory rate. Peimine and Peiminine not only feather typical character of modifier of MDR, but also differ from other moldifiers such as Calcium channel blocker, Cyclosporines in chemical structure, they belong to cevine groups alkaloid, a subgroup of C-Nor-D-homosteroid alkaloid.

浙贝母是临床常用中药，体外及动物试验证明，浙贝母中的有效活性成分贝母甲素和贝母乙素具有逆转肿瘤细胞MDR的作用，而且能逆转两种不同机制的多药耐药肿瘤细胞的耐药性，在无明显细胞毒剂量下，可使阿霉素对耐药肿瘤细胞的杀伤活性提高5-10倍，不但具备明确的多药耐药逆转剂的特征，而且在化学结构上属异甾类生物碱中的瑟文类生物碱，完全不同于钙离子拮抗剂、免疫抑制剂和其它现有的耐药逆转剂，具有作用靶点宽、化学结构独特的特点。

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.
