The ultrastructural changes during the development of sieve element companion cell complex (SE/CC complex) in Populus deltoides were investigated using electronic microscopy. The result showed that SE and CC tome from the same secondary phloem mother cell. The development of sieve element went through three stages, i. e. immature, mature, and degenerate stage. In immature stages the sieve element presented radial expansion, cell wall thickening, and production of sieve plastid and P-protein. The cytoplasma selectivly autolysed in mature stage. At the same time, karyoplasm was dispersed, and nuclear envelope was not clear, or karyoplasm was disorgnized, and nuclear envelope was clear. The karyopalsm finally turned into P-protein. In degenerate stage, the cytoplasm completely disappeared, and the function was lost.

利用电镜技术研究美洲黑杨次生韧皮部筛管和伴胞发育过程中细胞超微结构的动态变化，观察到筛管和伴胞由同一个次生韧皮部衍生细胞分裂分化形成筛管约发育历经未成熟期、成熟期和衰退期的变化未成熟期筛管分子表现为细胞的径向扩展、壁的增厚、筛管质体和P-蛋白质的产生；成熟期筛管分子细胞组分发生选择性自溶，细胞核核质弥散状，核膜不清晰，或核膜清晰而核物质降解，最后细胞核完全解体转化为P-蛋白质类的物质；衰退期筛管分子细胞质完全解体消失，失去功能。

Laboratory experiments were carried out to study the survival and development of the Harmonia axyridis feeding on Chaito phorus popleti on high insect-resisitance hybrid poplar 741(Pb29) and medium insect-resisitance hybrid poplar 741(Pbl7).The API 741 poplar was used as control.The mortality and development during immature period,adult,baby mass.eclosion and sex ratio of H. axyridis were measured.The results showed that:to contrast The API 741, Chaito phorus popleti on Pbl7 and Pb29 has no significantly impacts on eclosion,pupation, ecdysis,mortality of immature period and pupa stage;Although every development stage of ladybeetles were not affected to ,the pupal duration of ladybeetles was lowered than the control;The body mass,eclosion and sex ratio have no significant difference.

通过利用节肢动物群落及各个亚群落的物种丰富度、个体数、均匀度和优势集中性对多样性指数进行通径分析，表明了高抗Pb29和CK节肢动物群落及各个亚群落多样性指数与均匀度和优势集中性的相关系数最高，与其物种个体数关系最为不密切：对各组分进行通径分析均表明的多样性提高是建立在降低优势集中性和增加均匀度指数的基础上的，而且以优势集中性的直接作用效果较为显著。

Seed explants of Eleutherococcus senticosus produced somatic embryos directly ongrowth regulator-free medium. The results were showed that use low temperature stressmethod to relieve the Eleutherococcus senticosus seed conformation dormancy andphysiological dormancy, to induce seed germinate. Proliferation of Eleutherococcus senticosussomatic embryo without any plant growth regulathors was better in liquid medium containing1/3MS+sucrose 3%, and better in solid medium containing 1/3MS+sucrose 1%.Eleutherococcus senticosus secondary embryo was stick to matrix through espial of cytology.Eleutherococcus senticosus somatic embryo was cultivated some times to form immature frondin liquid medium, then transfer into solid medium to form full plant. The experiment wasindicated that much more Eleutherococcus senticosus immature frond can be cultured inbioreactor, so large-scale production in bioreactor culture can be done.

研究结果表明：低温胁迫处理刺五加种子可以打破种子的形态休眠和生理休眠，促使种子发芽：在不添加任何植物激素的培养基中诱导刺五加体胚形成，其中，1／3MS+3％蔗糖的培养基搭配有利于液体培养的刺五加体胚增值，1／3MS+1.0％蔗糖的培养基搭配有利于固体培养的刺五加体胚增值；在进行体细胞胚增殖时，体细胞胚继代三周后表面开始形成很多次生胚，对刺五加次生胚进行细胞学观察，发现刺五加次生胚与母体只是粘贴在一起；刺五加体胚需在液体培养基中培养一段时间形成幼植物体，实验表明可以通过生物反应器培养大量的刺五加幼植物体，然后转入固体培养基中形成完整植株，因此可以通过生物反应器培养进行规模化生产。

Using ST1KO mice, we have demonstrated that early B lymphopoiesis is impaired in the absence of STAT1, including reduced numbers of pro-B, pre-B, immature-B, and mature-B cells in BM. Interestingly, B220+CD138+ cells of ST1KO mice are also significantly decreased in BM as apposed to WT mice.

在本论文中，我们发现STAT1基因剔除小鼠的早期B淋巴球发育，不论在pro-B， pre-B， immature-B，或mature-B时期皆有明显的缺陷；特别的是，STAT1基因剔除小鼠的骨髓细胞(B220+CD138+)则有明显减少的现象。

No primitive blood cells were observed in liver, which implies that the liver was not the hemopoietic organ in C. mydas. The development of erythrocytes includes 5 stages: primitive, early, middle, late, and mature. The body sizes of these cells increased first, then decreased, and increased in the end. The development of granulocytes includes 5 stages also: myeloblast, promyelocyte, meddle immature granulocytes, late immature granulocytes, and mature granulocytes. The body sizes of them decreased; and the sublobe of the nuclear may indicate the aging.

Results of megascopic pyrolytic characteristics and the quantitative chemical dynamic analyses of these samples show that: although the occurrence and accumulation enrichment of immature and low mature oils are related to a number of different geological factors and conditions, under relatively low thermodynamic stresses organic matters related to immature and low mature oils do be matured to generate hydrocarbons.

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."
