Results The strongest photoinactivation effect occured in the HEP-2 cells co-cultured with 1 mmol/L ALA for 8 h. The killing activity of ALA-PDT to the HEP-2 cells was positively correlated with the power density of the irradiation (r=0.88, P＜0.05).Conclusions ALA-PDT can effectively kill the cultured HEP-2 cells in vitro. The optimal killing activity was related to the time and the power density of the laser irradiation.

结果 (1)光照时机选择在ALA与HEP-2细胞培养8 h时杀伤效应最强；(2)ALA-PDT对HEP-2细胞的杀伤效应与照光能量呈正相关r=0.88，P 结论 ALA-PDT能有效地杀伤体外培养的肿瘤细胞，其杀伤最佳效果与照光时机和照光能量有关。

The results indicated that the typical apoptosis was induced by PRRSV in lungs and uteri. The ultrastructural changes showed different characterizations at different stages of the infection. During the early stage from 8th h to day 3 postinfection,the apoptosis cells shrank,the cytoplasm concentrated,the chromatin condensed,the kernel disaggregated and the endoplasmic reticulum dilated. During the middle stage from day 5 to day 9 postinfection,the apoptosis cells evidently shrank,the cell membranes protu berated,the plastosome manifolded,and apoptosis bodies were found. During the last stage from day 10 upwards postinfection,the apoptosis bodies degenerated and disappeared,and no inflammation occurred. Few apoptosis cells were necrotic.

结果表明，PRRSV可诱导宿主肺和子宫发生典型的细胞凋亡，表现为细胞的超微形态结构随着病毒感染进程出现不同的特征性变化，早期（感染后第8 h至第3 d）凋亡细胞多表现为细胞体积缩小，细胞质密度增强，染色质浓缩，核仁解体，内质网扩张；中期（感染后第5 d至第9 d）凋亡细胞体积显著缩小，细胞膜突起，线粒体增多，有凋亡小体形成；晚期（感染后第10 d以后）凋亡细胞形态多表现为凋亡小体降解和消失，少数凋亡细胞在凋亡晚期表现为坏死细胞。

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。

All 31 YSTs (5 pediatric and 26 postpubertal) showed strong positive SALL4 staining in more than 90% tumor cells but had negative OCT4 staining. Both spermatocytic seminomas showed positive SALL4 staining in 80% to 95% tumor cells in all 3 types of tumor cells with weak-to-moderate staining intensity.

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.
