To sum up, both experiments in vivo and in vitro show that activating blood circulation to dissipate blood stasis has effects of inhibiting proliferation of malignant cell, inducing differentiations and impelling apoptosis. These perhaps were the machinisms of clinical effects. Considering the effects on DNA content, we dares inferred that YDQ inhibited proliferation by restraining the synthesis of DNA. It asks for our doing more work to research the underlying machinism with immunology, cytobiology, molecularbiology and so on.

总之，体内、体外实验均表明活血化瘀为主的疗法对恶性细胞有一定的增殖抑制、分化诱导和凋亡促进作用，这也许正是临床治疗MDS取效的原因所在，分析瘀毒清对细胞DNA含量的影响，我们推测认为瘀毒清可能通过抑制细胞DNA的合成进而抑制恶性细胞的增殖，其更深的机制尚待我们从免疫学、细胞和分子生物学等角度进一步研究揭示。

Mesenchymal stem cells are multipotent cells derived from many adult tissues, which can differentiate into cells of the mesodermal lineage, such as adipocyte, osteocyte and chondrocyte, as well as cells of other embryonic lineages. They are a promising tool for tissue engineering.

Results: ApoD was observed positively expressed in type2 astrocytes and oligodendrocytes from O2A lineage, while it was not expressed in type1 astrocytes from T1A lineage. Accordingly, we can verify the phenomenon found in the study of T1A and T2A gene different expression profile that ApoD mRNA was highly expressed in T2A and lowly expressed in T1A. Conclusion: It can be concluded that lipid metabolism related genes such as ApoD play important roles in the generation and differentiation of O2A lineage, which closely correlate with internal mechanism of lipid metabolism in the brain and myelogenesis.［Key words］astrocyte(T1A, T2A); oligodendrocyte; O2A lineage; apolipoproteinApoD

我们已采用基因芯片技术在mRNA水平研究两型星形胶质细胞的基因表达谱差异，发现ApoD在2型星形胶质细胞中差异高表达，故本文拟用激光共聚焦双重免疫荧光标记技术进一步在蛋白质水平观察ApoD在体外分化成熟的两型星形胶质细胞以及少突胶质细胞中的表达情况，以期为我们深入研究ApoD等脂代谢相关基因在脑内脂质代谢和神经髓鞘发育机制中所起的作用提供有用的实验依据，依此探讨胶质细胞发生和分化的信号机制。

Myoid/myofibroblastic areas in DFSP possibly represents the hyperplasia of stromal myofibroblasts, rather than true myofibroblastic differentiation of the neoplastic cells.

DFSP中的肌样／肌纤维母细胞性分化可能是肿瘤间质中肌纤维母细胞增生的结果，并非代表了瘤细胞的真性肌纤维母细胞性分化。

This review focuses on the current research progress of the liver cell differentiation source, and it also discusses the advantages and disadvantages of various hepatic stem cells and nonhepatic stem cells, expecting to provide a reference for liver cell source selection during tissue engineering, an adequate and suitable source for bioartificial liver and hepatocyte transplantation and to help to treat liver diseases.

本文着重论述了目前肝脏细胞的分化来源研究进展情况，并对各种肝源性和非肝源性干细胞的优缺点进行了讨论，以期为肝组织工程选择细胞来源提供参考，为生物人工肝、肝细胞移植提供充足、合适的细胞来源，协助治疗肝脏疾病。

The results of the ultrastructares of the glandular hairs show that there are a number of the plastids in which there are a big of osmiophilic substances in the secretory cells of the peltate hairs and then that there are much endoplasmic reticulum in the secretory cells of head hairs. The difference between them are with relation to the function.

腺毛超微结构观察的结果表明，盾状腺毛类分泌细胞的优势细胞器是质体，其中具大量的嗜锇物质；而头状腺毛类分泌细胞的优势细胞器是内质网，这种细胞器上的差异与头状腺毛和盾状腺毛的分泌功能是相适应的。

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.

To pronuclear formation rate after oocyte in vitro maturation 18 hours and parthenogenticactivation, oocytes derived from SM is significantly higher than oocytes from PM,oocytes derived from IM is significantly lower that of oocytes detrived from PM and SM.

对于孤雌刺激反应而言，无论是何种类型的卵母细胞成熟18小时后，自发成熟卵母细胞激活后形成原核的比率高于被动成熟的卵母细胞，诱导成熟的卵母细胞的原核形成率显著低于自发和／或被动成熟的卵母细胞。
