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。

Myoblastic cells from patients with PM had a weaker ability of developing into the myotubules, thus they were unable to perform effective regeneration, which resulted in a progressive necrosis. The exogenous bFGF could promote the division and proliferation of the muscle cells in vitro . These results shield a light on bFGF's potential role in preventing and treating PM.

PM患者受损腓肠肌在体外有再生能力，但融合成肌管能力极弱，存在再生障碍，不能对变性、坏死的肌纤维形成有效再生，故呈进行性肌纤维耗竭；外源性bFGF可促进PM患者体外培养骨骼肌细胞增殖分裂，并可促进肌管成熟，对进展性肌病应具有防治作用。

All results above indicated that:The expression of ERβand p-ERβin mouse ovary at oestrous cycle and in early gestational period changed regularly, it showed that ERβand p-ERβhad important effects to ovaries development, ovarian follicles groth, oocyte maturation and form corepus luteum in female mouse ovary during oestrous cycle and in early gestational period.

以上结果表明：ERβ及其磷酸化形式——p-ERβ在小鼠发情周期以及妊娠早期卵巢中表达有规律性的变化，揭示ERβ与p-ERβ在雌性小鼠发情周期及妊娠早期，对卵巢发育、卵泡生长、卵母细胞成熟和黄体形成有重要的作用。

The neutralizing activity of these antibodies and IgG fractions is acquired through post-translational modifications, through opsonization of virus particles into macrophages and immature dendritic cells, or through expression of antibodies on the surface of HIV-1-susceptible cells.

这些抗体或IgG片段的中和活性可以通过抗体分子翻译后的修饰，或介导巨噬细胞和未成熟树突状细胞的对病毒颗粒的调理作用，或者通过表达在HIV易感细胞表面来体现。
