Songs that make our hearts happy can make them stronger too, US researchers reported on Tuesday.
They found that when people listened to their favorite music, their blood vessels (血管) dilated in much the same way as when they are laughing, or taking blood medications.
"We have a pretty impressive effect," said Dr Michael Miller, director of preventive cardiology (心脏病学) at the University of Maryland Medical Center in Baltimore.
"Blood vessel diameter improved," he said. "The vessel opened up pretty significantly. You can see the vessels opening up with other activities such as exercise." A similar effect is seen with drugs such as statins.
When blood vessels open up more, blood flows more smoothly and is less likely to form the clots (凝块) that cause heart attacks and strokes. "We are not saying to stop your statins or not to exercise but rather to add this to an overall program of heart health," said Miller, who presented his findings to a meeting of the American Heart Association in New Orleans.
Miller's team tested 10 healthy, non-smoking men and women, who were told to bring their favorite music. They spent half an hour listening to the recordings and half an hour listening to music they said made them feel anxious while the researchers did ultrasound tests designed to show blood vessel function.
Compared to their normal baseline measurements, blood vessel diameter increased 26 percent on average when the volunteers heard their joyful music. Listening to music they disliked — in most cases in this group heavy metal — blood vessels narrowed by six percent, Miller said.
Miller said he came up with the idea after discovering that laughter caused blood to literally flow more smoothly. "I asked myself what other things make us feel really good, besides calories from dark chocolate of course. Music came to mind. ... It makes me feel really good," he said.
Most of the volunteers chose country music but Miller said the style is not so important rather than what pleases each individual.

Hospital emergency rooms treat injured fingers all the time. Without treatment，a bad cut can lead to permanent damage. But how should a person know when a bleeding cut is serious enough to require medical attention? We asked Dr. Martin Brown. Chairman of the department of emergency medicine at Inova Alexandria Hospital in Virginia.   

First，the medical term for a cut or tear in the skin is a laceration(严重划破，撕裂伤). Dr. Brown says the length is usually not as important as the depth. He says a long cut on a finger can likely be treated without a visit to a doctor if the wound is not very deep. “If you have a short but deep laceration where there’s been a structure underneath that's been damaged a tendon，a nerve，a blood vessel,”says Martin，“it may, in fact，need professional attention. ”

Some injuries —like a fingertip that gets cut off might even require surgery to repair. That requires a specialist to either file(锉平) down the bone or reattach the fingertip. More often，filing down the bone is what is done because reattaching a fingertip is often not successful.

How a wound bleeds can be a sign of how serious it is. Minor cuts usually produce what is known as venous(静脉)bleeding. This means the blood flows steadily from the injury. The bleeding will often stop when pressure is put on the wound. Dr. Brown says in most cases holding direct pressure with clean gauze or a cloth for four to five minutes should stop the bleeding. With a cut finger, holding the hand above the heart can reduce the loss of blood. But if a cut appears to be pumping blood out with some force，this may be a sign of arterial(动脉)bleeding. This kind of injury should be treated by a medical professional as soon as possible.

Even a cut that does not require medical attention must be kept clean to prevent infection. Small cuts should be cleaned gently with clean water. Use a washcloth to clean the area if the wound is dirty. Dr Brown says cuts should be covered with a clean, dry bandage.
