A new study suggests that the timing of a wound affects the speed at which it heals.
一项新的研究表明,受伤的时间会影响伤口愈合的速度。
Wounds suffered during the day heal around 60percent faster than those sustained at night.
白天受的伤愈合的速度比晚上的快60%左右。
The study showed how the body's circadian rhythm controlled 【 the healing of wounds 】.
伤口的愈合（过程）
这项研究显示了人体的生理节奏是如何控制伤口愈合的。
The 【 circadian rhythm 】 is like a clock or timer.
昼夜节律/（生物钟） body clcok
生理节奏就像时钟或计时器。
It tells our bodies when to wake up, eat and sleep in a cycle --
它告诉我们的身体在一个周期内什么时候醒来,什么时候吃东西什么时候入睡
【① a series of 】activities that repeat themselves 【② day after day 】.
① 一系列的……
② 日复一日（ 强调无变化 ）
Eg: I keep taking care of the injured rabbit day after day so the rabbit is recovering day by day.
这一系列 日复一日重复的活动。
Each cycle lasts about 24 hours.
每个周期持续24小时。
In the study, researchers found that
在这项研究中,研究人员发现,
skin cells moved faster to repair wounds sustained during the day.
皮肤细胞在修复白天的伤口时移动得更快。
The researchers examined cells, mice, and burn injury databases.
研究人员检查了细胞、小鼠和烧伤数据库。
Specifically, their investigation found the following information:
具体来说,他们的调查发现了以下信息:
Nighttime burns - burns suffered between 8 o'clock at night and 8 o'clock the next morning
夜间烧伤一在晚间八点至次日早晨八点的烧伤
were 95 percent healed after an average of 28 days.
平均28天以后愈合率到达95%。
But after an average of 17 days, daytime burns
但平均17天以后,日间烧伤
and 8 at night - were 95 percent healed.
早晨八点至晚间八点地烧伤一的愈合率就会达到95%。
In other words, nighttime injuries took an average of 11 days longer to heal.
换句话说,夜间烧伤平均需要比日间烧伤多花11天愈合。
The scientists say that circadian clocks 【 play an important part /role】 in healing.
在……起到重要作用/扮演重要角色
科学家们说,生物钟在伤口愈合过程中起着重要的作用。
Circadian clocks control many cells in the body
生物钟控制着人体的许多细胞,
and affect many biological processes, including
会影响包括睡眠在内的很多生理过程。
John O'Neill was a co-leader of the study
约翰奥尼尔是这项研究的联合负责人。
"This is the first time that the circadian clock within individual cells
他说,“这是首次证明个体细胞内部的生物钟
has been shown to determine how effectively they respond to injuries," he said.
能够决定它们应对损伤的效率。
