OBJECTIVE: To study the effects of prolonged 75% oxygen exposure on the expression of vascular endothelial growth factor and its receptors (VEGFR1 and VEGFR2) in the neonatal rat lungs and to elucidate the effects of prolonged exposure of high concentration of oxygen on lung vascular development and its relationship with bronchopulmonary dysplasia.

目的：研究持续吸入75%氧对新生大鼠肺血管内皮生长因子（vascular endothelial growth factor，VEGF）及其受体（VEGFR1和VEGFR2）表达的影响，探讨较高浓度吸氧对肺血管发育的影响及与支气管肺发育不良（bronchopulmonary dysplasia，BPD）的关系。

OBJECTIVE: To study the effect of hyperoxia exposure on high mobility group protein-B1 (HMGB1) expression in neonatal mice and the role of HMGB1 in the pathogenesis of bronchopulmonary dysplasia. METHODS: C57BL/6 mice were randomly exposed to 60% O2 or air 1 day after birth.

目的：检测高迁移率族蛋白B1（HMGB1）在高浓度氧（60% O2）暴露新生小鼠肺组织损伤模型中的表达水平，探讨HMGB1在支气管肺发育不良发病机制中的作用。

Result］ The new buds and petals of I.germanica was proper to be used as explant of tissue culture, with lower browning rate compared with other positions. The well situated tissue block of explant (3 mm×3 mm×3 mm) might reduce browning rate. Adding 0.1%Vc or 0.3% active carbon in medium had obvious effect on preventing tissue browning. The exogenous hormone 2 mg/L 6-BA was easy to lead to brownness turning, and 2 mg/L Kt and 2 mg/L NAA brought less effect to tissue browning. When using disinfectants of alcohol, its dipping time of 5～10 s for explant was the best, with the minimum browning rate. The culture under full illumination condition was liable to induce brownness turning, compared with other cultured conditions, the brownness turning could be restrained effectively by using imitating artificial climate condition for culture.

结果］ 鸢尾的新生芽和花瓣较适宜作组织培养的外植体，与其他部位相比褐变率较低；外植体组织块适中（3 mm×3 mm×3 mm）可降低褐变率；在培养基中加入0.1%Vc或0.3%活性炭对防止组织褐化效果明显；外源激素2 mg/L 6-BA易引发褐变，2 mg/L Kt和2 mg/L NAA对组织褐变影响不大；使用乙醇消毒剂时，对外植体浸泡时间以5～10 s为佳，褐变率最低；全光照条件培养容易诱发褐变，采用仿人工气候条件培养较其他条件培养可有效抑制褐变的发生。

The disease which can cause degeneration and broken of bruch's membrane can have choroidal neovascular.

所有可以引起后极部玻璃膜破裂和变性的病变均有产生脉络膜新生血管的基础。

These findings indicate whether Bruch's membrane is destroyed or kept untouched may be crucial for the development of CNV.

小鼠视网膜、脉络膜色素丰富，可以充分吸收激光能量，导致Bruch's膜破损，生成脉络膜新生血管。

Chain reactions are triggered which lead to retinal pigment epithelium degeneration,Bruch's membrane breakdown, CNV formation, AMD and blindness in the end.

经过一系列反应，最终导致视网膜色素上皮细胞变性、Bruch膜断裂、脉络膜新生血管形成、老年黄斑变性、失明。

The stroken on the fundus of rabbit by small spot,short time exposure and macro-power laser could break up the Bruch's membrane and induce the choroidal neovascularization.

激光小光斑，曝光时间短，能量过大击射有色家兔眼底，可引起玻璃膜破裂，诱发脉络膜新生血管。

The Brunel International Office co-ordinates a meet-and-greet service from Heathrow and an orientation programme for new students.

国际学生办公室安排在 Heathrow 机场的接机服务，并为新生安排熟悉环境的入校介绍活动。学校还设有供各种宗教举办聚会活动的厅堂。

In my works , synthesis of the Jesus and the machine emphasize on the relationship of Mind body and religion ; synthesis of infant and machine means training mind will bring new birth and hope; the last synthesis through human figure and animal machine express that the mind want to shake off the yoke of the body that take along with the brutalism.

其中，耶稣与机器的结合着眼于这种身心状态与宗教的关系，而婴儿与机器的结合强调内心修炼将会带来人的新生和希望，野兽机器与人的结合则把灵魂隐喻为欲挣脱身体枷锁的人，而野兽机器则代表我们的身体和身体本身携带的兽性。

And danced upon the newly budded leaves, would you know me, mother?

又在新生的树叶上跳舞，妈妈，你会认识我么？

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
