2 . In a first-of-its-kind surgery, a 57-year-old patient with terminal (晚期的) heart disease received a successful transplant of a genetically-modified (转基因的) pig heart and is still doing well three days later. It was the only currently available option for the patient. The historic surgery was conducted by the University of Maryland Medical Center (UMMC).
This organ transplant showed for the first time that a genetically-modified animal heart can function like a human heart without immediate rejection by the body. The patient, David Bennett, a Maryland resident, is being carefully monitored over the next weeks to determine whether the transplant provides lifesaving benefits. He had been considered ineligible for a traditional heart transplant at UMMC and several other leading transplant centers that reviewed his medical records.
“It was either die or do this transplant. I want to live. I know it’s a shot in the dark, but it’s my last choice,” said Mr. Bennett, the patient, a day before the surgery was conducted. He had been hospitalized for the past few months.
Before the surgery, three genes, responsible for the rejection of pig organs by humans, were “knocked out” in the donor pig (供体猪). Six human genes responsible for immune acceptance of the pig heart were put in. Lastly, one additional gene in the pig was knocked out to prevent unreasonable growth of the pig heart tissue, which totaled 10 unique gene edits made in the donor pig.
“This was a breakthrough surgery and brings us one step closer to solving the organ shortage crisis. There are simply not enough donor human hearts available to meet the long list of potential receivers,” said Bartley P. Griffith, Doctor of Medicine, who surgically transplanted the pig heart into the patient. Daniel Maluf, Doctor of Medicine, said: “This event is the final achievement of years of research and testing from our multidisciplinary (多学科的) team and represents a beginning of a new era in the field of organ transplantation medicine.”

6 . In a new move, doctors are using feature films in order to encourage their patients to talk more freely about their problems. Supporters of “film therapy (疗法)” say that discussing characters and plot lines from a proper film can help people to understand their feelings better.
One of those using the method is Dr Zhang, a doctor from Shanghai, who charges ¥250 for a one-hour “film therapy” session. He said, “I was treating a woman who had been badly heartbroken in a relationship, and who was experiencing such strong feelings that it was difficult for her to speak about them. I told her that her situation reminded me of On the Waterfront, when the hero realizes his brother is dishonest and he feels a great sense of betrayal (背叛). My patient identified so easily with him that she started to cry. Watching and discussing the film unlocked all the feelings she had buried. Each time she watched and cried, she felt better.”
Dr Zhang admits that film therapy does not work for everyone, but says he has used it successfully with about a third of his clients. “Through the films’ characters, plots and even music, it allows people to face their problems.” He said that Falling Down, in which Michael Douglas plays the part of an unemployed man who is so depressed that he uses violence, was an example of the dangerous results of not letting anger go. “I used this film with a patient who was very upset because he was holding back a lot of the anger he felt towards people who had hurt him,” said Dr Zhang. “We talked about Michael Douglas’s character and the disastrous path he takes, and my patient then realized that he needed to let go of his feelings more regularly so as not to burst out like a time bomb.”

10 . Each year, half a million people die from brain aneurysms(动脉瘤)—when a blood vessel(血管)bursts in the brain. An aneurysm is a bulge(膨胀)in a blood vessel that can burst. If that happens in the brain, it can be deadly. For survivors, physical disabilities are often severe. They may include memory problems, loss of balance, trouble speaking and even blindness. But new technologies are increasing survival rates and reducing disabilities.
Beaumont Bacon is a survivor who makes light of her experience because she is a comedian(喜剧演员). She uses humor to make others laugh. Now she’s working on a new show. Michael Alexander is her doctor. He operated on Beaumont Bacon after her attack. “She had bleeding in the frontal area of her brain, so right above the eyes. The part that was in the brain was about maybe the size of an egg. So, that’s a fairly large bleed.”
Ms. Bacon had a better chance at survival than most people because of Dr. Alexander. He directs the Neurovascular Center in Los Angeles. The center offers new technologies that include placing a catheter(导管)into an aneurysm, then threading wires to promote blood clots(血栓). This technique reduces the chances of another burst blood vessel. “You don’t have to open up the skull(头盖骨)or open up the brain to do surgery. It’s all done from inside the blood vessels. So it reduces the amount of blood loss, and the recovery is much faster.”
For Beaumont Bacon’s recovery, the hospital worked to prevent problems commonly found in patients with a burst aneurysm. The problems include brain swelling that can shut down blood vessels. She spent a month in a coma(昏迷)—unable to communicate with doctors, friends and loved ones. But with a year of treatment, she recovered. Now, she is making people laugh.
