Gene therapy is a medical treatment that aims to change a few of a patient’s genes to cure a genetic disease.
基因治疗是一种医疗，旨在改变一些患者的基因来治愈遗传疾病。

大约在同一时间，美国东部宾夕法尼亚州的费城儿童医院宣布在那里接受治疗的11岁男孩进行了类似的改善。 早些时候，中国研究人员发表了一项研究，显示了另外两个孩子的相似改善。
The experimental methods, or therapies, target only one rare condition. But scientists say similar treatments could someday help many more children with other kinds of deafness caused by genes.
实验方法或疗法仅针对一种罕见条件。 但是科学家说，有一天类似的治疗可能会帮助更多的儿童患有基因引起的其他耳聋。
Around the world, 34 million children have deafness or hearing loss. And information from the U.S. Centers for Disease Control and Prevention says genes are responsible for up to 60 percent of cases.
在世界各地，有3400万儿童有耳聋或听力损失。 美国疾病控制与预防中心的信息说，基因最多造成60％的病例。
