The CDC has issued a set of reports showing that the lung disease associated with vaping seems to be declining from peak rates, and that Vitamin E acetate seems — as speculated early on — to be the prime suspect for the epidemic. The affliction has cost at least 54 lives and affected 2,506 people across the nation.
美國(guó)疾病控制和預(yù)防中心（CDC）發(fā)布的一系列報(bào)告顯示，電子煙引起的肺病病例數(shù)量此前達(dá)到峰值后，現(xiàn)在似乎正逐步下降。如之前推測(cè)的那樣，維生素E醋酸酯似乎正是此流行病的罪魁禍?zhǔn)住?/div>

The condition now officially known as EVALI (E-cigarette, or Vaping, Product Use-Associated Lung Injury) appeared over the summer, with hundreds of people reporting chest pains, shortness of breath and other symptoms.?
疾病的官方名稱(chēng)是EVALI（E-cigarette, or Vaping, Product Use-Associated Lung Injury），即電子煙或電子煙產(chǎn)品使用引起的肺部損傷。這種狀況在今年夏季出現(xiàn)，數(shù)百人報(bào)告胸痛、呼吸短促或其他的癥狀。

When state medical authorities and the CDC began comparing notes, it became clear that vaping was the common theme between the cases — especially using THC products.
國(guó)家醫(yī)療部門(mén)和CDC比較記錄時(shí)發(fā)現(xiàn)，吸電子煙是這些病例的共同點(diǎn)，特別是使用四氫大麻酚。

Before long the CDC recommended ceasing all vape product usage and was collating reports and soliciting samples from around the country.?
不久前，CDC建議停止使用所有電子煙產(chǎn)品，并對(duì)報(bào)告進(jìn)行核對(duì)、在全國(guó)范圍內(nèi)征求樣本。

Their medical authorities have now issued several reports on the disease. The most significant finding echoes earlier indications that Vitamin E acetate, an oily substance that was apparently being used as a cutting agent in low-quality vaping cartridges, is at the very least a major contributor to the condition:
他們的醫(yī)療部門(mén)現(xiàn)在發(fā)布了疾病方面的數(shù)份報(bào)告。最重大的發(fā)現(xiàn)重復(fù)了之前的猜想，維生素E醋酸酯，一種用于劣質(zhì)電子煙煙彈中的油性物質(zhì)，至少是病情的一個(gè)主要誘因。

Building upon a previous study, CDC analyzed bronchoalveolar lavage (BAL) fluid from a larger number of EVALI patients from 16 states and compared them to BAL fluid from healthy people.?
在之前研究的基礎(chǔ)上，CDC分析了來(lái)自16個(gè)州的EVALI病人的大量支氣管肺泡灌洗液（BAL），并將其與健康人的BAL液進(jìn)行了比較。

Vitamin E acetate, also found in product samples tested by the FDA and state laboratories, was identified in BAL fluid from 48 of 51 EVALI patients and was not found in any of the BAL fluids of healthy people.
在51名EVALI病人中，48人的BAL液中都含有維生素E醋酸酯，而健康人的BAL液中不含這種成分。在美國(guó)食品及藥物管理局（FDA）和國(guó)家實(shí)驗(yàn)室檢測(cè)的產(chǎn)品樣本中也發(fā)現(xiàn)了維生素E醋酸酯。
