Since 1997, the goose flocks in some regions of South and East China have experienced severe outbreaks of Newcastle disease virus infection. The results of the in vitro tests indicate that the goose isolates have stronger ability to induce syncytium formation, when compared to chicken and pigeon isolates.

1997年以来我国华南和华东部分地区发生了由新城疫病毒(Newcastle disease virus， NDV)导致的鹅的临诊疾病，而且发现鹅源NDV在体外具有比鸡源和鸽源毒株更强的致细胞融合的能力，这表明NDV的抗原可能发生了变异。

The main research achievements on oogenesis and embryogenesis in mammals are described in this review,including the resumption of meiotic division;activation of MⅡ oocyte;development of parthenogenetic,gynogenetic,androgenetic and reconstituted embryos;and the genetic and reproductive potentials of chromosomes within the first and the second polar body.

本研究将论述哺乳动物卵子发生和胚胎发生的最新研究进展，包括：减数分列的启动， MⅡ期卵母细胞的激活，孤雌胚、雌核胚、雄核胚和重组胚的发育以及第一与第二极体染色体的遗传和生殖潜力。

Epidermal cells near the wound dedifferentiate and proliferate forming blastema and/or migrate to the wound plane forming a pre-epidermis consisting of several layers of stem cells covering the wound plane, which then re-differentiates further forming fully developed epidermis. Cells in the parietal peritoneum are also induced by injury to dedifferentiate into stem cells which then proliferate and migrate along the parietal peritoneum to the wound place forming a pre-peritoneum which re-differentiates into fully developed parietal peritoneum.

伤口愈合包括伤口闭合、顶端表皮层及体腔上皮的新生：创伤后的前4 d，残腕顶端的肌肉组织向伤口处迁移并重排使伤口闭合；创伤附近的表皮层细胞发生脱分化并增殖后迁移到创伤面形成由数层干细胞组成的前表皮层，之后进一步分化形成表皮层；而体腔上皮细胞在创伤诱导下也脱分化并增殖，然后沿体腔上皮迁移到创伤处形成&前体腔上皮&，经再分化形成新的体腔上皮。

A clear cause-and-effect relationship between excessive myocardial MMP-1 activity, increased mysial collagen degradation, and progression to systolic HF has been shown experimentally through the use of transgenic models and the use of pharmacological MMP activators.53,54 In addition, experimental evidence has been provided showing that following chronic neurohormonal activation, increased synthesis and release of MMPs into the local extracellular matrix of the cardiomyocyte occurs,55 which in turn could contribute to endomysial and perimysial collagen degradation and disruption.

一个明显的因果过多的心肌MMP-1关系活动， mysial增加胶原蛋白的降解和进展收缩性心力衰竭已被证明试验，通过使用转基因模型和使用的MMP药理作用此外，activators.53，54实验证据下面被提供显示慢性神经激活时，增加的MMPs合成和释放到当地的细胞外基质的心肌细胞发生，55反过来有助于人肌内膜和 perimysial胶原退化和破坏。

The molecular mechanism in hypertensive kidney lesion was demonstrated by monitoring the levels of serum TGF-β, nitric oxide and plasma AngH in essential hypertensive patients and investigating the effect of information convection in endothelial cell on fibrillar collagen metabolism and its relationship with hypertensive kidney lesion.

该课题通过测定原发性高血压病人及伴肾脏损害病人的TGF-β_1、NO和Ang Ⅱ的水平，探讨内皮细胞产生的信息传递对纤维胶原代谢的影响及与高血压性肾损害的关系，以揭示高血压性肾损害发生发展的细胞分子机制。

Result 1. CDK4, P16 were expressed in parabasal layers and the upper layer, mainly in the prickle and granular layers of cholesteatoma epithelium. Their positive rates were 68.6% and 88.6% respectively. Statistical analysis showed that there was a significant difference in positive rates between

CDK4与P16在中耳胆脂瘤上皮中均过度表达且有一定程度的正相关性，表明它们在疾病发生中是共同而非单独起作用的，从细胞周期的角度可反映胆脂瘤上皮细胞过度增殖的同时也增强负调控因子来抑制增殖，使凋亡同时加快而达到新的平

The development of HLA-peptide tetrameric complexes to directly visualize HBV specific CD8+ T cells has recently provided the opportunity to investigate the relationship between HBV-specific CDS* T cells and liver damage in more details.

Fetramer技术结合胞内因子染色和表型分子的检测，近年来使人们对CTL 的认识迅速达到单个细胞水平，并从T细胞分化的角度对慢性持续性病毒感染的发生机制有了全新的认识。

Were analyzed under different nutritional levels. The results showed that in tuber development, under- or over-supply of nutrients reduced ZT content at initial stage and IAA, ABA and JA content at middle stage, but increased GA content in the whole process, which caused GA/ABA and GA/JA to be off balance in the key stage of tuberization.

结果表明，过低、过高的营养供给，降低了块茎发育前期细胞分裂素的含量，中期细胞生长素的含量以及促进块茎发育的脱落酸、茉莉酸含量，增加了各时期促进匍匐茎发生的赤霉素含量，导致在块茎形成和膨大的关键时期，GA/ABA和GA/JA比值失衡，抑制了块茎的正常发育。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
