Bushy cell是位于耳蜗腹侧核(ventral cochlear nucleus，VCN)的一类细胞，由于声音信息大部分是通过它被传递到上橄榄核(superior olivary complex，SOC)进而进行声源定位信息处理，因此，bushy cell的信息处理特性对于听觉系统声源定位有重要的影响。

ABSTRACT Objective To discuss the clinical pathologic features and differential diagnosis of mixed germ cell sex cord stromal tumorwith malignant variant of germ cell tumor Methods The clinical pathologic datum and immunophenotype were studied in the case of ovary MGCSCST with malignant variance of germ cell tumor Results The patient's genital anatomy and female phenotype were normal,karotypes was 46xx with uterogestation The tumor tissue consisted of mixed germ cells and sex cord stromal cells with evident malignancy of mixed germ cells There was no atypical structure of gonadoblastoma in tumor tissue Conclusion MGCSCSST has complex morphosis,thus,to prevent misdiagnosis,more samples should be collected and more slices be cut The patient may have prognosis malo when there are high malignant variants of mixed germ cells in tumor tissue

目的 探讨混合性生殖细胞性索间质肿瘤(mixed germ cell sex cord stromal tumor，MGCSCST)伴恶性生殖细胞肿瘤变异型的临床病理特点及鉴别诊断。方法卵巢MGCSCST伴恶性生殖细胞肿瘤变异型的病例进行临床病理特征和免疫表型分析。结果患者生殖器的解剖结构和女性表型正常，染色体组型是46xx，足月妊娠。肿瘤组织由混合性生殖细胞和性索间质肿瘤构成，混合性生殖细胞有显著的恶性特征。瘤组织中没有典型的性腺母细胞瘤结构。结论 MGCSCST有复杂的形态结构，因此更多的取材和切片可以防止误诊，当肿瘤组织中的混合性生殖细胞有高度恶性变异时，患者预后不良。卵巢肿瘤；生殖细胞性索间质肿瘤；免疫组织化学

Because the techniques of the biochemical waste treatment are very important, the techniques of the cultivation of the microorganism have received more attention in recent years. A study is conducted to analyze the steady states and dynamic bechavior of the reactions of the cell-substrate and the prey-predator interaction in two chemostats in series. For the reaction of cell-substrate in two chemostats in series, if the specific growth rate of the Monod model is used for the cell , there are three types of steady states for this reaction system. These three types of steady states and stability are analyzed in detail. The dynamic behavior of this reaction system is analyzed by the numerical method and computer graphs. The results show that the dynamic behavior of this system consists of stable steady states.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
