Confusion is one symptom of a concussion.
錯亂是腦震蕩的一種癥狀表現(xiàn)。
But confusion may also characterize decisions about how soon to let an athlete play after taking a hit to the head.
但憑借這種癥狀或可對于運動員頭部遭受撞擊后多久重返賽場起到?jīng)Q定作用。
Sizing up symptoms such as dizziness and nausea is subjective, after all.
畢竟頭暈、惡心等癥狀的表現(xiàn)有些主觀。
Now a study suggests that a blood test could objectively determine whether or not the damage is bad enough to put a player on the bench.
而現(xiàn)在一項研究表明血液測試可以客觀地評定運動員傷勢是否嚴(yán)重到換下的程度。
The work is in the Journal of Neurotrauma.
這項研究已經(jīng)在《神經(jīng)創(chuàng)傷雜志》上發(fā)表。
A strong blow to the head causes chemical changes within nerve cells that damage their structural proteins.
頭部遭受的猛烈撞擊會使得神經(jīng)細(xì)胞發(fā)生化學(xué)變化，進(jìn)而造成結(jié)構(gòu)蛋白損傷。
Among the debris is a protein fragment called SNTF—which in more severe cases, spills into the bloodstream.
而這些損傷碎片當(dāng)中是一種被稱為SNTF的蛋白質(zhì)片段，在傷勢嚴(yán)重的情況下它會進(jìn)入血液中。
The new study followed 20 professional hockey players who got concussions with symptoms that lasted six days or more.
這項新研究對20名職業(yè)曲棍球運動員進(jìn)行跟蹤調(diào)查，這些運動員都有長達(dá)6天及以上的腦震蕩癥狀。
And blood levels of SNTF were much higher one hour to six days later than were levels of the protein fragment in eight other athletes who had gotten concussions that cleared up within five days.
相比其他8位遭遇腦震蕩后5天內(nèi)就進(jìn)行治療的隊友，癥狀持續(xù)1小時至6天多的運動員們血液中的SNTF結(jié)構(gòu)層次相對較高。
Levels were also low in 45 non-concussed players tested during the preseason.
而賽季前測試的45名未遭受腦震蕩的球員的SNTF結(jié)構(gòu)層次也非常低。
A blood test for SNTF might thus forecast recovery time from a head injury.
因此SNTF的血液測試或許能預(yù)測頭部受創(chuàng)的恢復(fù)時間。
Combined with other neurological tests, levels of this molecule could help doctors tell athletes when it's safe to suit up again.
結(jié)合其它神經(jīng)系統(tǒng)測試，這種分子的結(jié)構(gòu)層次將有助于醫(yī)生判斷運動員何時可以重新披掛出陣。
