BBC在线收听下载:新型血检可早期查出8种癌症

Hello, I'm Neil Nunes with the BBC News.

Scientists have taken a step towards one of the biggest goals in medicine, a universal blood test for cancer. A team at Johns Hopkin University in United States has tested a method called CancerSEEK on a thousand patients to see if it could detect 8 types of the disease. The test showed us success rate of 70%. Rates of detection were lowest when the cancer was at an early stage. The doctor Nickolas Papadopoulos who led the study said it offered great hope. We would like to detect them in stage I but even if we detect them in stage II, the chances of these individual surviving are higher than waiting for this cancer to become stage III or so. So it's not bad that it can detect the cancer even if it's not at the earliest stages.

The parents accused of holding their 13 children in shackles at their California home have pleaded not guilty to charges of torture, abuse and forced imprisonment. The children are rescued after one escaped through a window of their house，east of Los Angeles. A District Attorney Mike Hestrin said the children of David and Louise Turpin were found severely malnourished with brain and nerve damage. He said they have suffered frequent brutal punishments. The victims report that as the punishment starting many years ago, they began to be tied up first with ropes and then when that victims were able to escape the ropes, these defendants eventually began using chains and padlocks to chain up the victims to their beds for weeks or even months at a time.

The US House of Representative has passed a bill to temporally fund the government operations for a month and avoid to shut down federal agencies when their existing funding expires this weekend. But the bill must still be approved by the Senate where it faces uncertain future. The Republicans do not have enough votes but Democrats are refusing to support any bill that doesn't include protection for undocumented immigrants brought to the US as children.
