美国研制新药物 或能让人"长生不老"

A new drug called "fountain of youth pill" has been discovered, according to the scientists from the University of California. This drug makes people live longer by boosting their immune system.

加利福尼亚大学的科学家日前宣称，一种新型药物“青春之泉”已被研制出来，该药物能够增强人体免疫能力，进而延长人类生命。

The medication contains the drug lenalidomide which stimulates immune cell production. This improves the body's ability to fight off bugs or tumors which often causes an overall decline in health in older people. Researcher Edward Goetzl called the drug a "fountain of youth pill".

该药物所含的来那度胺能够促进免疫细胞生长，提高人们与病菌和肿瘤对抗的能力（正是病菌和肿瘤导致老年人身体状况恶化）。研究人员爱德华葛佐称该药为“青春之泉”。

Goetzl said the pill would not necessarily make people live longer but that they would be healthier and enjoy a better quality of life. He added large scale trials are expected next year, and the drug will be given to over-65s alongside vaccines.

葛佐称，“青春之泉”并不是所谓的“长生不老药”，它只能让人更健康、生活质量更好。他还称，该药将于明年被投入大规模试用，并通过疫苗注射的方式在65岁以上的老年人群中得到推广。

However, despite the low doses Goetzl said he would never advise giving it to young women. Lenalidomide has a structural similarity to thalidomide which was linked to birth defects.

然而，尽管用量小，葛佐建议年轻妇女不宜使用该药品。因为来那度胺同（治疗孕吐的）沙利度胺结构类似，而后者会导致婴儿出生缺陷。
