When they are released into the extracellular environment, or when they are membrane-bound and in contact with the pericellular zone, these enzymes degrade a broad range of connective tissue proteins and are important during the development of healthy tissue as well as in remodeling damaged tissue.

当它们被释放入细胞外环境，或者是与膜结合后与细胞外环境保持接触时，这些酶能够使大范围面积的结缔组织蛋白酶降级，这样对健康组织的发育以及对受损组织的重塑相当重要。

Recently, compression of peripheral nerve roots due to enlarged epidural venous plexus has been described as a possible cause of back and radicular pain, too.

近来，由于硬膜外静脉丛曲张导致外周神经根的压迫也被认为是引起背痛和神经根痛的一个可能的原因。

Whereas changes in extravascular lung water of less than 100-200% are undetectable by other clinically applicable methods of lung injury assessment (chest radiograph and oxygenation), the single transpulmonary indicator has proven highly sensitive to small (10-20%) increases and is therefore useful to detect incipient pulmonary edema.

尽管肺血管外水分在小于100-200%的变化能够通过其他评估肺损伤的方法来评价，但是单向跨肺热指示剂法被证实能够敏感到发现10-20%的肺血管外水分的变化，因此对于发现初始的肺水肿更为有用。

Whereas changes in extraascular lung water of less than 100-200% are undetectable by other clinically applicable methods of lung injury assessment (chest radiograph and oxygenation), the single transpulmonary indicator has proen highly sensitie to small (10-20%) increases and is therefore useful to detect incipient pulmonary edema.

尽管肺血管外水分在小于100-200%的变化能够通过其他评估肺损伤的方法来评价，但是单向跨肺热指示剂法被证实能够敏感到发现10-20%的肺血管外水分的变化，因此对于发现初始的肺水肿更为有用。

The crowd of 54,246 at Yankee Stadium was disappointed as Rodriguez again fell short of his 500th home run. A-Rod lined out to deep rightfield to end the eighth inning.

洋基球场中塞满54246名球迷再度失望了，没看到A-ROD轰出生涯500轰。A-ROD在第八局击出了一颗深远的界外飞球被右外野手接杀。

According to the light reflecting principle, the light is reflected between the walls until to the angle reflector which can make the light ray return the emission point along the original way.

当光幕中间进入外物时，光束即被截止，光接收装置接收不到反射光，控制装置就判断门之间出现了外物，立即通知后续处理单元采取开门动作。

The results showed that: a great quantity of compacted callus were induced on the MS medium supplemented with 6-BA and a large amounts of corms and young seedlings were differentiated on the differentiation medium, but plenty of loosened callus on the MS medium supplemented with 2,4-D and limited young seedlings on the differentiation medium.

结果表明：在附加6-BA的MS培养基上，外植体可诱导出大量的致密愈伤组织，而且致密愈伤组织在分化培养基中能分化产生大量圆球茎和幼苗；而在附加2，4-D的MS培养基中，外植体被诱导出疏松愈伤组织，在随后的分化培养基上只能产生数量有限的幼苗。

Gelatin microsphere is firstly made by encapsulating bFGF into gelatin by special manufacture process, then this microsphere was combinated into PLGA conduit or PLGA film.when used, we need only pack the injury peripheral nerve, injury spinal cord, wounded pars encephalic with the PLGA conduit. The conduit or film can slowly release buff which would be absorbed by around tissues.bFGF was already proved to be nutritious to the regeneration and alive of neuron and protect injury neuron.bFGF can also promote morphogenesia and division of nerve cell which would raise the survival rate of neuron, guide the generation of axon etc.bFGF is one of the important factors of sustaining the normal survival of cholinergic nerve.

使用时，只需将此材料贴敷外周损伤神经伤患处，脊髓伤口，或在脑部开颅手术后填充于术后创面，可有效地在伤口局部缓慢地释放并由机体组织吸收bFGF等神经营养因子。bFGF等已被证明具有神经营养作用，可促进神经元的再生与存活，保护受损的神经元。bFGF等对神经细胞兼有促进形态发生与分裂作用，具有提高神经元的成活率、诱导轴突向外生长等功能，是维持前脑基底部胆碱能神经元正常生存的重要因素。

As the hydraulic system works, the capacity of oil box will change at any moment. When the capacity decreases, the air will enter the moisture absorption after filtered. The desiccant in the absorption sorbs the moisture, then the desiccated air bursts through the entry single way valve and comes into the oil box, at the same time the atmosphere outside the oil box will close the deflated single way valve.

液压系统工作时油箱液面会随时发生变化，当液面下降时油箱外的空气被滤清器过滤后，进入吸湿器，吸湿器内干燥剂吸收空气中的水分，干燥后的空气推开进气单向阀进入油箱，同时油箱外大气关闭放气单向阀。

The new Japanese first lady has made headlines in the past for tales of her alien encounters: in a book published last year, she wrote about an extraterrestrial experience some 20 years ago when she said her soul rode on a triangular-shaped UFO and went to Venus while her body was asleep.

过去日本新任第一夫人由于她外星旅游的童话故事被大肆报道。在去年出版的一本书上，她写到自己在20年前又一次外星球去的经历，他的灵魂乘着三角形的UFO并去了金星，然而她的身体还在睡觉。
