The reasons of RA focus on disbalance of immunity net, the effect of so many cytokines and MMPs , and the tumor-like proliferation of fibroblast-like synovicytes in joints, though the cause of developing disease is unknow.

RA的发病过程中，免疫网络失衡，加上成纤维样滑膜细胞(fibroblast-like synoviocytes，FLS)的类肿瘤样生长及所分泌的大量促炎性细胞因子、趋化因子和金属蛋白酶，是导致关节内炎性细胞聚集，滑膜细胞增生和向周围组织侵蚀及基质降解和破坏的主要因素。

Results CT showed a intrapelvic mass of rectal wall or surrounding soft tissue with inequality of size, relation closeness with intestinal wall; rectall wall different degree compression and narrowing,and extruding surrounding tissue.Below 5cm tumor density were slightly reduced,but symmetrical. Exceed 5cm tumor moderately enhanced, but asymmetrical. CT value of major mass were 25-35Hu, with boundary zone nodule enhancement, contrast-enhanced CT value 50-60Hu, and centricity necrosis.

结果 （1）盆腔内直肠壁或直肠周围软组织肿块，大小不等，肿块与直肠壁关系密切；（2）直肠不同程度的受压、变窄，肿块主要向直肠腔外生长，对周围组织产生推挤压迫；（3）径线在5cm以下肿瘤平扫时密度稍低，但均匀，增强时表现为中等度均匀强化，无坏死；径线在5cm以上10例肿块密度平扫时呈稍低密度且不均匀，CT值25-35Hu，增强时较大的肿瘤边缘带中等度结节样强化，CT值50-60Hu，肿块中心部分无强化，呈坏死样改变。

To compare the growth characteristics of non-hematopoietic adult stem cells derived from rat fetal blood and rat bone marrow in vitro, and to study the differentiation of these stem cells into neuron-like cells in vitro,the fetal blood of pregnant rats and bone marrow of adult rats were sterilely collected; mononuclear cells were isolated by using standard Ficoll-hypague techniques and then cultured in DMEM/LG containing 10% fetal bovine serum.

为了比较大鼠胎血和骨髓中非造血成体干细胞（non-hematopoietic adult stem cells，NASC）体外培养过程中的生长特性及体外诱导两者向神经元样细胞分化的异同，在无菌条件下采集孕大鼠的胎血和成年大鼠的骨髓，用Ficoll-hypague分离液分离出单个核细胞后，种植于含10%胎牛血清的DMEM/LG培养液内。收获的NASC传代培养，用流式细胞仪检测细胞的免疫表型。

The effects of vacuolization on the differentiation of vascular endothelial cells were analyzed from a chemical biochemistry genetics perspective using the blastodisc cells differentiation model induced by FGF with the γ-butyrolactones derivative.

从化学遗传学的角度，利用γ-丁内酯衍生物研究了成纤维细胞生长因子（fibroblast growth factor， FGF）诱导鸡胚盘细胞向血管内皮细胞分化过程中，空泡化对血管内皮细胞分化的影响。

Parasitizing specially in the cytoplasma of small granular hemocytes, RLOs formed an inclusion body in host cell, in which, RLOs propagated in mass and caused the host cell swelling and disorganizing, subsequently released and infected other target histocytes, resulted in the arising of such symptoms as debility and shivering of limbs, etc..

RLOs专一性寄生于小颗粒细胞的胞质内，以包涵体的形式生长繁殖，随着RLOs的快速增殖，包涵体内RLOs数目显著增多，且多呈圆形，包涵体极度膨胀，将细胞核压向周边，最终细胞被胀破，释放出RLOs再去侵染其它组织和器官，造成颤抖、肌无力等全身症状。

RESULTS:①Growth and adhension of osteoblasts: 24 hours after inoculation, osteoblasts were fully adhered to the wall in the BPCB group and cover slip group.

细胞在材料上的生长及附着：随着培养时间的延长，附着于材料表面和孔隙的细胞数量逐渐增多，并向孔隙内部长入，细胞形态以多角形为主。

The infection of rhizobia to rice was a dynamic process beginning with surface colonization of the rhizoplane (especially at lateral root emergence), followed by endophytic colonization within roots, and then ascending endophytic migration into the stem base, leaf sheath, and leaves where they developed high populations.

同时，根瘤菌还可以沿植物的表面从根到地上部分迁移。在植物的生殖生长阶段，内生根瘤菌仍然保持活动性，可以进入烟草子房的子房壁、胎座和胚珠内，暗示根瘤菌通过种子向子代垂直传播的可能性。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
