In this study, we examined the effect and the mechanism of ANP on porcine oocyte maturation, fertilization and giant panda spermatozoa function.

本文以猪和大熊猫为对象，研究了ANP在卵母细胞成熟和精子功能中的作用及机理。

Part II The experiment study on anti-tumour effect of dendritic cells derived from peripheral blood monocyte of patients with oral cancer after pulsed by tumour antigen in different ways. Collected 50ml peripheral blood from each patients and volunteers to induced DC in vitro. We parted the test group and control group into three subgroups respectively, untreated group A, freezed and thawn group B, RNA transfected group C. To group A, after induced DCs for five days , we added 200U/mlTNF-α in each hole and cultured on. To group B, we added protein antigen (DC/ tumor cells = 1 : 1 ,each hole) for 4h at 5d, and then added 200U/mlTNF-α in each hole and cultured on. To group C, transfected immature DC with tumor cell RNA(DC:RNA=1×105/ml: 5ug)at 5d, operated completely with the specification of invitrogen DMRIE-C reagents. After transfection we replaced transfection agent with complete medium, and then added 200U/mlTNF-α in each hole and cultured on.

第二部分口腔癌患者外周血来源的树突状细胞体外负载抗原后抑瘤作用的实验研究无菌采集20例口腔癌患者和20例健康志愿者外周血50ml，分离单个核细胞体外诱导培养DC，并将实验组和对照组细胞各分为三组，A组为未处理组，B组为冻融组，C组为RNA转染组。A组DC在培养5d后，每孔加入TNF-α200U/ml；B组DC培养第5d后，每孔中加入癌细胞蛋白抗原，使DC/肿瘤细胞=1：1，继续培养4h后，每孔加入TNF-α200U/ml；C组将培养至第5d的未成熟DC用肿瘤细胞RNA进行转染(DC：RNA=1×105/ml： 5ug，按照invitrogen DMRIE-C试剂说明书进行操作)，转染结束后用完全培基取代转染剂，每孔加入TNF-α200U/ml。

The toxical effects of environmental chemicals, biomedical agents and physical agents can greatly influence the developing kidney. They have a gravely bad effect on the development and health of children.

外界环境中的化学物质、生物及物理因素的毒性作用可损害未成熟肾脏的发育，并严重影响胚胎和儿童的正常发育和身体健康。

Glucocorticoids are effective in inducing apoptosis via the uncharacterized mechanisms in many hematological malignancies. GC-induced apoptosis is initiated by, and strictly dependent upon, the interaction of GC with its receptor, the GR.

糖皮质激素(glucocorticoid，GC)通过与其特异性受体-糖皮质激素受体(glucocorticoid receptor，GR)结合，不仅可诱导未成熟胸腺细胞凋亡，而且对急性白血病细胞、淋巴瘤细胞、骨髓瘤细胞等均有促凋亡作用，诱发凋亡正是应用糖皮质激素治疗白血病的分子生物学基础。

The biological characteristics of the CCM are mainly relevant to the unmaturity of the vessel wall. A series of angiogenic factors play an important role in the development of the lesion. The proliferative activity of the CCM needs to be studied further. The different clinical presentations of CCM was based on its pathological diversity.

CCM生物学特性主要与其血管壁组织结构的不成熟有关，各种血管因子发挥了相当重要的促进作用，CCM本身的增殖活性有待进一步研究；CCM不同的临床表现与其病理特点的差异密切相关。

The results showed that the expression of calm3 and trm112l genes had no remarkable differences in oocytes and 8-cells stage embryos, but were significantly different in blastocysts. It was supposed that these two genes were possibly maternal genes, and they might be involved in oocyte maturation and zygotic genome activation.

结果显示，在卵母细胞和8细胞期胚胎，基因calm3和trm112l的表达量无显著性差异，而在囊胚期的表达量与前两个时期的表达量存在显著性差异，推测这两个基因在牛胚胎发育过程中的表达可能属于母型调控，提示该基因在卵母细胞成熟和合子基因激活中起一定作用。

The fertilization was processed by sperm in mature male gametophyte combining with egg cell on the top of archegonia on June 15 or so.

摘要樟子松发育成熟的雄配子体中的精子6月15日左右在颈卵器中上部与卵细胞结合，进行受精作用，其后，受精卵进行游离核分裂，形成8个子核时，开始形成细胞壁。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
