Cases of the abnormal sex differentiated diseases in children were presented. Among them, there were 4 cases of Turner's syndrome, 1 Klinefelter's syndrome, 9 female pseudohermaphroditism, 2 male pseudohermaphroditism, and 4 true hermaphroditism.

本文报道小儿性分化异常疾病20例(包括先天性卵巢发育不全综合征4例、先天性睾丸发育不全综合征1例、女性假两性畸型9例、男性假两性畸型2例、真两性畸型4例)，对上述病例进行了细胞染色体核型分析，同时作了口腔上皮细胞性染色质、中性粒细胞核鼓植体及尿17酮类固醇、17羟类固醇的检查。

In a cocultivation experiment, hepatoma derived HepG2 cells, but not NB4 cells, methylate radiolabeled iAs〓.

与iAs〓相反，MAs〓O既不降解PML-RARα蛋白或恢复PML核体正常的分布模式，也不诱导NB4细胞分化。

The ovine testicular tissue survived and its volume increased significantly, but it failed to differentiate to reach spermatogenesis.

结果表明，添加CsA组与不添加组的移植试验结果无显著差异；移植入的羊睾丸组织块可在受体动物中存活，体积明显增大，但不能分化以实现精子发生。

The results showed that the cell wall organization during anther development failed to divide into inner-wall, middle and tapetum normally, and not to provide material, energy and information transfer for the development of pollen mother cells, resulting in the occurrence of abnormal pollen mother cells separatist period; thus which could not form a normal pollen grains which led to abortion.

结果表明，不育花药壁组织在发育过程中，没有分化形成正常的内壁、中层及绒毡层，不能为花粉母细胞的发育提供物质、能量和信息的传递，造成花粉母细胞在减数分裂期发生异常，不能形成正常的四分体，因而未能形成正常的花粉粒而导致败育。

In T cells,TGF-beta1 can inhibit their proliferation,inhibit the differentiation of Th1 and Th2,inhibit the differentiation of CTL,induce the generation of regulatory T cellsTregin B cells,TGF-beta1 can inhibit their proliferation,induce IgA class switch,it also can induce the apoptosis of immature and resting B cells;in NK cells,TGF-beta1 can inhibit the secretion of IFN-γand the cytolytic function of NK cells.

对T细胞，TGF-beta1可以抑制其增殖，抑制Th1和Th2细胞的分化，抑制CTL的分化，诱导调节性T细胞的产生；对B细胞，TGF-beta1可以抑制B细胞的增殖，诱导IgA的类别转换，还可以诱导不成熟和静息B细胞的凋亡。

If the ratio or the concentration of 2, 4-D was higher, the callus formed quickly, but it was hygrophanous, and easy to necrosis, conversely, if the ratio or the concentration of 2, 4-D was lower, the callus appeared very slowly or could not form, and adventitious root formed directly or indirectly.

比值较高（或2，4-D浓度较高）时愈伤组织出现的时间较早，但愈伤色泽不好，呈半透明水渍状，易于褐化死亡，而比值较低时，愈伤出现得很慢或不形成愈伤，且易于直接或再分化形成不定根；这些不定根长至1.5-2.0cm时就不生长，并逐渐褐化。

Though can not accurate induce neural stem cells specific orientation differentiation yet,to accompany the unceasing deepen recognize of convection mechanisms in cells' signal convection and discovery of new cell facter,new chemo-signal, Homo sapiens would solve the question of orientation differentiation from totipotential stem cell,multipotential stem cell to neural stem cell, orientation nerver ancestor cell then special tipe neural cell, implementation functional reconstruction betwen neural cell,for ultimate solve the proble of neural regeneration developing the way.

尽管目前尚不能准确有效的诱导神经干细胞特异性定向分化为某种特定的神经元，但随着人们对细胞间信号传递机制认识的不断加深和新的细胞因子、化学信号的不断发现，人类将能够解决从全能干细胞、多能干细胞到神经干细胞、定向神经祖细胞直至特异类型神经细胞的定向分化，完成神经元之间的功能重建，为最终解决中枢神经再生这一难题而开辟道路。

Short of seeing relatively large areas (greater than one 100x microscopic field) of glial neoplasm without admixed dysplastic neurons, I usually would not call it a ganglioglioma.

缺乏相对大区域（大于100倍显微镜视野）不混合存在分化不良神经元成分的胶质瘤成分，我通常不诊断为节细胞胶质瘤。

Interestingly, for the typology of "Male Autonomy, Female Cooperate," although the female students intervene in the triangulation to some extent and their self-differentiation appeared unfavorable, when coupled with male college students who were well-differentiated, the relationships were favorable.

有趣的是，「男自主女配合」的类型中，虽然女大学生有某种程度介入亲子三角关系，以及自我分化程度不甚良好的现象，但是与分化良好的男大学生成为情侣后，彼此的关系仍相当良好。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
