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。

Furthermore, preliminary work also performed to examine whether PI3K/AKT signal transduction pathway was activated in the process of refractory leukemia development. Materials and methods An immortalized human bone marrow stromal cell line, HS-5, was introduced to establish a bi-phase culture system for the cultivation of B-lineage precursor leukemia cells. ELISA and RT-PCR were used to investigate the expression of VEGF and its receptors in the leukemia cell lines and primary childhood leukemia cells in different treated groups. Flow cytometory method and immunofluorescent staining were employed to examine the apoptosis signals both in the VP16 treated and untreated leukemia cells. Western blot was utilized to explore the PI3K/AKT activated status in the drug induced or uninduced leukemia cells and lymphocytes from healthy donors.

材料和方法使用来源于人类骨髓基质细胞的细胞株HS-5作为滋养层细胞进行急性淋巴细胞性白血病细胞的体外培养，通过细胞生物学和免疫学方法评估培养体系并鉴定出难治性白血病细胞克隆；以ELISA和RT-PCR方法检测急性白血病细胞株和患儿白血病细胞VEGF及其受体的表达，了解不同治疗阶段VEGF及其受体的表达状况，并结合临床指标进行分析，明确VEGF及其受体在白血病发生过程中的作用；流式细胞仪和免疫荧光染色法对正常健康儿童、初发白血病患儿、复发白血病患儿及缓解后患儿进行凋亡因子检测和分析，初步阐明难治性白血病抗凋亡形成的原因；蛋白印记分析检测PI3K/AKT信号传导通路在健康儿童、初发白血病和复发白血病患儿的表达，初步了解难治性白血病形成的分子生物学机制。

Some views think MBO have cheating operation that lead to the state assets losses; I think MBO , as a kind of comparatively ripe system , its must not cause the loss of state assets , the objective factor influenced state assets price is much, higher or lower than net assets price may not reasonable , may not unreasonable either, the cause leading the loss of state asset is unsufficiency condition and not canonical means. We should consider interior employee especially outstanding the historical contribution factors of administrators.

笔者认为MBO作为一种较为成熟的制度，其本身并不必然导致国有资产流失，但国内影响国有资产合理定价的客观因素多而复杂，国有资产转让价格高于或低于净资产未必合理，也未必不合理；国有资产流失的原因是在条件不充分的情况下，用不规范的方法实施MBO；某些企业作低价是因为考虑了内部职工尤其是优秀管理者的历史贡献因素；当前首要目标是改制，提高社会整体经济效益，应在合理范围内以法律形式明确管理层收购价格优惠制度，促进MBO的顺利进行。

本研究结合人类学和社会学关于代际关系的相关理论，围绕&近代中国社会代际关系&的命题展开，以&五四时期知识分子的代际冲突&为具体的研究对象，用报纸杂志、人物往来书信、著作等作为主体材料，通过分析知识分子思想表达的方式，揭示出知识转型导致代际关系变化这一深层次原因，并就与中国社会代际关系相关的若干问题提出自己的看法。

This is permissible although "pure reason," as was the case with the same use of terms in our first work, is only intended to denote reason in its theoretical employment, and although there is no desire to bring under review its faculty as practical reason and its special principles as such.

It is box of this machine top, the Venus that is the old Microsoft that lets world software industry first plans to fold halberd heavy sand in China, do not have soundlessly breath, without result and return, lose face; greatly next, again the UTSTARCOM that in China's very famous beautiful beard entrepreneur Wu Ying leads centers firepower onslaught, final and same also be hold the bag, the tear asperses battlefield; but, regard game of a network as the company, because one lets the outside look unidentified the matter that wants not to understand, appear on the market in the success grandly later, also abandoned unexpectedly oneself bilk the network game with succeeding, in tying the grand case that took this to be less than light soon directly.

Tier rating: Tier 2 Watch List - China is on the Tier 2 Watch List for the fourth consecutive year for its failure to provide evidence of increasing efforts to combat human trafficking, particularly in terms of punishment of trafficking crimes and the protection of Chinese and foreign victims of trafficking; victims are sometimes punished for unlawful acts that were committed as a direct result of their being trafficked, such as violations of prostitution or immigration/emigration controls; the Chinese Government continued to treat North Korean victims of trafficking solely as economic migrants, routinely deporting them back to horrendous conditions in North Korea; additional challenges facing the Chinese Government include the enormous size of its trafficking problem and the significant level of corruption and complicity in trafficking by some local government officials 2008

三层评价：第2级观察名单-中国是第2级观察名单连续第四年其未能提供证据证明越来越多的努力，打击贩卖人口，特别是在惩治贩运犯罪和保护中外贩卖活动的受害者；受害者有时惩罚非法行为，承诺的直接原因是他们被贩卖的，如卖淫或违反移民/移民管制；我国政府继续处理朝鲜贩卖活动的受害者仅仅作为经济移民，经常驱逐他们回到可怕的条件下在北朝鲜面临更多的挑战包括：中国政府的巨大规模的人口贩运问题，相当程度的腐败和共谋贩运一些地方的政府官员

German philosopher whose idealistic system of metaphysics was highly influential; it was based on a concept of the world as a single organism developing by its own inner logic through trios of stages called "thesis, antithesis, and synthesis" and gradually coming to embody reason.
