BACKGROUND: Compared with adult mesenchymal stem cells, yolk sac-derived MSCs of early embryo have stronger self-renewal capacity and plasticity. Moreover, they could differentiate into angioblast and hemopoietic stem cells during embryonic development and trigger embryonic angiogenesis and hemopoietic tissue development.

背景：与成体间充质干细胞相比，来源于早期胚胎的卵黄囊间充质干细胞有更强的自我更新能力和可塑性，且在胚胎发育过程中可分化为成血管细胞和造血干细胞，启动胚胎血管发生和造血组织发育。

被诱导的心肌细胞的判定除常规指标外，我们还用了心脏特异性引物β-MHC对不同收缩时间的心肌细胞总RNA进行RT-PCR扩增和RNA斑点杂交，发现该心肌细胞不仅具有正常心肌细胞的特性，而且在分化早期就高度地表达心脏特异性基因。

Sixty-three cases of AFP-positive gastric carcinoma were divided into four subtype: hepatoid type 22 cases (34.9％), fetal gastrointestinal type 15 cases (23.8%), and mixed type of the hepatoid type with enteroblastic differentiation to be 24 cases(38.1%), and yolk sac tumor-like type 2 cases (3.2％).

应用光镜、电镜、组化和免疫组织化学方法，对87例AFP阳性胃癌中临床病理资料较完整的63例进行病理组织形态观察，并用2例3个月妊娠的胚胎胃肠组织以同样方法行相关的对比研究。

Hepatoid variant of yolk sac tumor: Usually seen under 25 year old woman. You shoud search other areas to see if there is classic reticular pattern of YST. IHC can include AFP.

肝样卵黄囊瘤：经常发生于25岁以下的女性中，观察其他区域是否具有卵黄囊瘤典型的网状结构，免疫组化包括AFP。

Results Incidence of AFP-positive gastric carcinoma was 6.2%(87/1395). Sixty-three cases of AFP-positive gastric carcinoma were divided into four subtype: hepatoid type 22 cases (34.9％), fetal gastrointestinal type 15 cases (23.8%), and mixed type of the hepatoid type with enteroblastic differentiation to be 24 cases(38.1%), and yolk sac tumor-like type 2 cases (3.2％).

结果：AFP阳性胃癌的发生率为6.2％（87/1395例）。63例中依据其病理组织形态学特点和肿瘤组织内癌细胞AFP染色阳性表达，并对比3个月妊娠胚胎胃肠组织学的改变，将其组织学类型分为4个亚型：肝样型22例（34.9％），胎儿胃肠型15例（23.8％）和肝样型伴肠胚分化的混合型24例（38.1％）以及卵黄囊瘤样型2例（3.2％）。

Here we performed an immunohistochemical study of a novel stem cell marker SALL4 in a large series of 110 primary testicular GCTs (65 pure and 45 mixed) containing the following types of tumors and/or tumor components: 50 intratubular germ cell neoplasias, 62 classic seminomas, 2 spermatocytic seminomas, 39 embryonal carcinomas, 5 pediatric and 26 postpubertal yolk sac tumors, 7 pediatric and 25 postpubertal teratomas, and 5 choriocarcinomas.

在此，我们给110例睾丸原发性GCTs（65例单纯性、45例混合性）做了SALL4免疫染色，研究了这个新标记的诊断效用。

Tissue transcription analysis indicated that chIL-2Rγ mRNA was found in cerebrum,cerebellum,medulla spinalis,bursa of fabricius,thymus,spleen,bone marrow,cecal tonsil,stomachus glandularis,stomachus muscularis,jejunum,yolk sac diverticulum,ileum,cecum,rectum,heart,kidney,lung,liver,skeletal muscle and skin, but was not detected in duodenum and testis.

RT-PCR检测发现，鸡IL-2Rγ mRNA分布于大脑、小脑、脊髓、腔上囊、脾、胸腺、骨髓、盲肠扁桃体、腺胃、肌胃、空肠、卵黄囊憩室、回肠、盲肠、直肠、心脏、肾、肺、肝、骨骼肌和皮肤，而在十二指肠和睾丸中没有检测到其转录。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
