For many cancers, radiation is one of the most common treatments.
对许多癌症来说，放射治疗是最常见的治疗方法之一。
While the therapy targets malignant cells, it also destroys nearby healthy ones.
虽然治疗的目的是杀死恶性细胞，但它也破坏了附近健康的细胞。
Yujiang Fang led a team at the University of Missouri, investigating ways to minimize that damage.
来自密苏里大学的于建方带领他的团队进行研究，希望能够将危害降到最低。
They knew that resveratrol, a compound in red grapes and red wine makes cancer cells more responsive to radiation therapy.
他们知道白藜芦醇对放射治疗非常敏感，它是一种红葡萄和红葡萄酒中的化合物。
Blueberries also contain resveratrol as well as flavonoids, chemicals that may have antioxidant, anti-inflammatory and antibacterial properties.
蓝莓中也有白藜芦醇还有黄酮类化合物，这些化学物质或具有抗氧化、消炎和抗菌的特性。
Using human cervical cancer cell lines to mimic clinical treatment, they found that blueberry extract improved the effectiveness of radiation.
使用宫颈癌细胞系模拟临床治疗，他们发现蓝莓提取物提高了放疗的有效性。
We reduce the dosage of radiation, but the killing effect of cancers not reduced, and even enhanced.
我们减少了辐射剂量，但对癌细胞的杀伤效果并没有减少，甚至增强了。

Radiation decreased cancer cells in the study by approximately 20%,
研究中放疗能减少大约20%的癌细胞，
the cell group that received only blueberry extract had a 25% decrease in cancer
只接受蓝莓提取物的癌细胞群体减少了25%，
but the biggest decline occurred in the group that got radiation and extract, a decrease of about 70%.
既接受化疗又接受蓝莓提取物的癌细胞群体减少了大约70%。
Fang says that the mechanism that makes blueberry extract so potent also reduces the growth of new cancer cells.
方认为这种可以让蓝莓提取物如此有效的机制还能抑制新癌细胞增长。
Blueberry extract itself has two effects, one is to inhibit proliferation at the same time promote cell death.
蓝莓提取物本身有两个作用，一是抑制细胞增殖，同时促进细胞死亡。
The team is now studying other fruits and vegetables for their potential cancer-fighting properties.
该小组也在研究其他水果和蔬菜的潜在抗癌性能。
