Results The clinical manifestation of brain stem hemorrhage secondary to cerebral infarction included sudden onset,evelution abruptly,coma,quadriplegia,higher fever and respiratory failure. CT usually do not identify the high dense location of brain stem. Large infarction of cerebral hemisphere may lead to shift the brain laterally and downward to produce herniation with subsequent brain stem compression,shift and distortion. Secondary brain stem hemorrhage occured usually in midderline area of midbrain or pontine.

The results showed that:Under NaCl stress,the reductions in the shoot and root dry weight, leaf area,stem diameter of grafted plant were lower than those of ungrafted plants.The Na~+ content,Na~+/K~+ ratio,Na~+/Ca~(2+) ratio in the leaf and scion stem of grafted plants were lower whereas those of in the rootstock stem ad root were higher than in ungrafted plants. The K~+ contents,soluble sugar contents,shoot water contents,SOD,POD,CAT,APX activity,the stability of AsA/DHA,Photosynthetic rate,transpiration rate and stomatal conductance were higher,whereas the MDA contents in the leaf of grafted plants were lower than that in ungrafted plants.The reductions in leaf area and stem diameter of grafted \'Jinchun No.2\' plants were more severe than those of grafted \'Zaoduojia\' ones.

结果表明，盐胁迫下，嫁接苗地上部和根干重、叶面积、茎粗降低的程度显著低于自根苗；嫁接苗叶片和接穗茎中Na~+含量和Na~+/K~+、Na~+/Ca~(2+)比值显著低于自根苗，而砧木茎和根中的Na~+含量和Na~+/K~+、Na~+/Ca~(2+)比值显著高于自根苗；嫁接苗叶片中K~+含量、可溶性糖含量、地上部含水量、SOD、POD、CAT、APX活性、AsA/DHA的稳定性、光合速率、蒸腾速率、气孔导度显著高于自根苗，MDA含量显著低于自根苗。

For assisting identification of crude drug Herba Dendrobii. Methods Morphological and histological studies were carried out on 11 medicinal plant roots in Dendrobium Sw. by microstructural observation. The 11 species were divided into three groups according to their stem morphology: a pair fleshy-stem group, including D. chrysanthum, D. crepidatum, D. primulinum, D. hercoglossum, and D. crystallium; b thick-and rigid-stem group, including D. fimbriatum and D. aurantiacum var. denneanum; c node-or inter- node- bulgy-stem group, including D. findlayanum, D. gratiosissimum, D. pendulum, and D. wardianum. The surface descriptions of velamen were conducted for D. fimbriatum and D. aurantiacum var. denneanum which are similar in characters of cross section.

方法利用形态组织学方法，对茎多肉质的束花石斛Dendrobium chrysanthum及其易混的玫瑰石斛D.crepidatum、报春石斛D.primulinum、重唇石斛D.hercoglossum、晶帽石斛D.crystallium；茎粗硬的流苏石斛D.fimbriatum及其易混的叠鞘石斛D.aurantiacumvar.denneanum；茎节或节间肿胀的棒节石斛D.findlayanum、杯鞘石斛D.gratiosissimum、肿节石斛D.pendulum和大苞鞘石斛D.wardianum共11种药用石斛根进行显微结构研究；对根横切面结构相似的流苏石斛和叠鞘石斛，配合进行了根被表面制片观察。

Distributed of Dactylopius eonfususquantity on different spot of cactus and to cactus stem piece selective researchThrough the stochastic selection parasitism has on Dactylopius confusus\'s cactus adult plant investigation in the greenhouse,finally indicated:The grain most likes parasiting on two level of stem pieces,next is the level stem piece,on three level of stem pieces parasites quantity are least.

胭脂虫在仙人掌植株上的分布及对仙人掌茎片的选择性研究通过在温室中随机选取寄生有胭脂虫的仙人掌植株上的胭脂虫调查，结果表明：胭脂虫最喜欢寄生在二级茎片上，其次是一级茎片，三级茎片上寄生的胭脂虫数量最少。

The bodies have much greater potential to regulate spermatogonial stem cell proliferation and differentiation. The dosage of GFRα1 mRNA produced by undifferential spermatogonial cells regulates the signal transduction of glial cell-derived neurotrophic factor so as to regulates the direction of spermato gonial stem cells: at a low level, spermatogonoial stem cell favors differentiation; at a high level, spermatogonial stem cell favors self-proliferation.

GFRαl在小鼠生精恢复过程中以剂量相关性调控著胶质细胞源性神经营养因数资讯传人，从而调控著精原干细胞的去向：高剂量时诱导其增殖，低剂量时诱导其分化。

In this study, the ovarial cancer stem cells were successfully obtained through the suspension culture of the ovarian cancer 0VCAR3 cell line in serum-free media. The stem cells formed spherical colonies, called "ovarispheres", and showed anchorage-independent ability. Furthermore, the bionomics and morphology of the stem cells were observed, and the expression difference of the tumor stem cells marker-ABCG2 between ovarispheres and anchorage-dependent cells was identified by using RT-PCR and Immunocytochemistry methods.

本研究通过无血清悬浮培养人卵巢癌细胞系OVCAR3，获得具有非锚着依赖能力的肿瘤干细胞球，观察其生物学特性及形态学的变化，并采用半定量逆转录—聚合酶链反应及细胞免疫化学的方法鉴定肿瘤干细胞标志ABCG2在贴壁细胞及肿瘤干细胞球中的表达差异。

BACKGROUND: At present, studies show that a kind of stem cell community which in many kinds of organizations can differentiate into tissue cells of different embryonic layers; but those are different from embryonic stem cells, embryonic stem cell will lose the part differentiation potential gradually during the development of pregnancy, and will present some special phenotypes or the molecular markers, as CD105 and so on, will call it postembryonic pluripotent stem cells.

背景：目前研究认为在胚胎发育后的多种组织中存在一类干细胞群体，可分化为不同胚层的组织细胞；但又不同于胚胎干细胞，随着妊娠期间胚胎的发育胚胎干细胞会逐渐失去部分分化潜能，会出现一些特殊表型或分子标记，如CD105，称其为胚胎后亚全能干细胞。
