There are some interesting strategies, some of which are remarkably simple, like cell phthalazine, which affect survival pathways, may be beneficial in clearing stellate cells from an injured liver without harming the surrounding hepatocytes or parenchyma cells.

还有一些有趣的策略，其中有些非常简单，如细胞酞嗪，可影响细胞存活的途径，可能对清除星状细胞有用，而不会损伤周围肝细胞或实质细胞。

Three categories of cytokines, including Thl/Th2 cytokines, chemokines and adipocytokines, are involved in the physiopathological process of NASH. In order to elucidate the significances of cytokines in the pathogenesis, serological diagnosis, and treatment efficacy evaluation of HASH, we reviewed the documents on the relationship between cytokines and non-alcoholic steatohepatitis.

参与NASH病理生理过程的细胞因子归纳起来有3类，即Th1、Th2细胞因子和趋化因子及脂肪细胞因子，本文了回顾3类细胞因子与NASH发生、发展关系的最新研究进展，从而阐明细胞因子在NASH发病机制、血清学诊断和治疗效果评价等方面的意义。

Results The study showed that immunoreactivity to SPR was present both on the surface and in the cytoplasm of epithelial cells, eosinophils, glandular cells and its ducts, mast cells, plasmocyte and other monocytes.

结果 SPR广泛分布于健康鼻粘膜上皮细胞、血管内皮细胞、腺细胞及导管、肥大细胞、嗜酸粒细胞、浆细胞和其它单核细胞。

Studies on the regulation of malignant phenotype expression in a mouse plasmocytoma cell line (SP2/0) by means of cellular engineering techniques of cell hybridization between the fusion of the mouse myeloma cells with rat intermediate or late erythroblasts.

三、利用细胞杂交的细胞工程手段，首次系统地研究了大鼠中幼、晚幼成红细胞与小鼠浆细胞瘤（SP2/0）细胞融合后恶性表型的表达状态，分析自然去核前红细胞胞质对骨髓瘤细胞恶性增殖的调控作用，以及晚幼期固缩核重新被激活的可能性。

Methods Routine immunization of BALB/ c mice by a tansfected cell line 293T/ B7-H4 as antigens.Then the immunized spleen was fused with SP2/0,a kind of plasmocytoma cells, and screen the positive clones by FCS with the 293T/B7-H4 as a positive control while 293T/ mock as the negative control.

以高表达人B7-H4分子的基因转染细胞株293T/B7-H4为免疫原，常规免疫BALB/c小鼠，采用B淋巴细胞杂交瘤技术进行细胞融合，并以该基因转染细胞293T/B7-H4作为阳性筛选细胞，以转空质粒的对照细胞293T/Mock作为阴性对照细胞。

The therapeutic mechanism of the method of nourishing qi, activating blood, dispersing phlegm and promoting the collaterals was supposed as that it intervened the airway remodeling and alleviated the progress of airflow obstruction of COPD by suppressing the chemo taxis of cytokines, regulating the proliferation of fibroblast cell and smooth muscle cell and preventing the proliferation and plerosis of extracellular matrix.

推测益气活血化痰通络法防治COPD的机制可能为：通过抑制炎症细胞的趋化、影响细胞因子的活性、调节成纤维细胞和平滑肌细胞的增殖、阻止细胞外基质的增生修复，从而达到干预COPD患者气道结构重塑，减缓COPD气流受限进展的作用。

The human cartilages are composed of chondrocyte and extracellular matrix , the form of chondrocytes are hypertrophy and the quantity are less; the ECM of cartilage are compised of type Ⅱ collagen and proteoglycan. Articular cartilages are all hyaline with little fibers. Trauma and arthritis are the main cause of cartilage injury, the ommilayer injury ofcartilage can be recovered by marrow, but because of without stimulation mechanism, the new tissues are merely fibrocartilages, they can not be coincide with hyaline cartilage in menchanics; the purely damage of articular cartilage can not stimulate chondrocyte to regenerate because of without blood circulation, thus, the plerosis of articular catilage can not depend on the proliferation of local chondrocyte. Ever since, people tried their best to find a way to reconstruct articular cartilage.

中文题名人骨髓基质干细胞成软骨诱导及多孔复合材料作为细胞载体的体外实验研究副题名外文题名 Cartilage induction of human mesenchymal stem cells and experiment on compound porous materials as cells' scaffold in vitro 论文作者刘晓岚导师周江南学科专业外科学研究领域\研究方向学位级别博士学位授予单位中南大学学位授予日期2003 论文页码总数68页关键词骨组织工程软骨细胞骨髓基质干细胞壳聚糖高分子外消旋聚乳酸馆藏号BSLW /2003 /R68 /10 造成人体关节软骨损伤的原因主要为创伤和关节炎，关节软骨全层损伤可由于骨髓中间充质干细胞的高速增殖修复，但这种修复由于缺乏相应的刺激机制，只能形成纤维软骨，而不能形成符合关节生理、力学要求的透明软骨；单纯软骨部分损伤软骨组织内无血管，软骨细胞迁移迟缓，无法使损伤区域软骨细胞再生，因此，关节炎及关节创伤后的软骨修复不能依赖于软骨细胞的增殖和迁移。
