Change head with sad technology ethics clearance nerve fiber cannot be born again

The strange tales "in such a story, Lu Ling Yang Scholar Award Jules found Dan's heart hair orifices are stuffed, so thou didst pick a replacement for him. From daejin Agur Dan Evans, and soon, the first name in the scholar, a study of successful again in the fall. Later, when Jules Dan mentioned his wife face not beauty, Lu sentenced and surgeon to Zhu wife swap on a beauty. At that time this is undoubtedly the ancients unfettered imagination. But now for the heart, lungs, spleen, kidneys, and so have become a reality,

The poll, is also able to change it for? "-head of" from us how far? it is not possible in fable, or in the near future will be able to achieve? in medicine "header for" footsteps and advance to the next what?

Getting at the root of the Exchange was a great hit in head fake news

In 2001, a surgeon in the United States physician for head of news had to make a lot of heated discussions, this also gives the public full of curiosity and anticipation of experts excited, but the final result was undoubtedly gave this is ice period of "head of" reduced temperature. In multi-party verification, we found that he was severely "swiping" a turn, it's just a "making" false news, is the author in order to highlight the buzz, the United States a neurosurgery experts Dr. White United States in the scientific man magazine published an article on the possibility of human head transplantation, graft of the article quoted out of context.

However, white in his article does say that, as early as 1970, he and his assistant have first primates — has changed in rhesus monkeys head surgery, surgery of rhesus monkeys live for eight days, not only has a consciousness, and you can eat, eyes can follow people move around indoors. His research group have also been ported to the human head has taken the first step. They produced a kind of device, you can put in circulation of blood to the head temperature is maintained at 10 degrees Celsius, so that the brain metabolism slows, to let the skull in the blood supply is cut off after 1 hour, saved as "head of" the implementation of the valuable time. Articles published in white, also referred to the one called the Vito Horwitz, this person as a diving accident cause limb weakness, and an interview with white is known first willing to put his skull donor for white people used operation.

Difficulties of a nerve fiber cannot be born again, "the head of" can only be on paper

If you want to add a skull and strange body connected, first of all to vascular suture, which is in modern medicine is not a problem, but cannot be linked to successful nerve bundles? you know, the brain and spinal cord is human nerve centers, human neural activity is in the neurons in the cerebral cortex by issuing instructions, through the spinal nerve, and then transfer to the activities of the organ and, therefore, is the surrounding the spinal cord and the brain activity of organs of connection Centre, in the neck to a few square centimeters of the cross-sectional area of the body all the nerve fibers. "Nerve fiber specifically? can say countless, then good doctors and machines can connect one is reattached, broken nerve fiber is not re-growth. At least the current face of cervical spinal fracture, medical institutions throughout the world in the clinic on the powerless! "Tsinghua second affiliated hospital neurosurgery Director Chan Kwok-keung stressed that all the nerve fibers could not be broken," the head of "can only be on paper.

No independent life, head of meaningless

Institute of Tsinghua University brain diseases, Dr Sun ZhaoHui, brain death is not very difficult, as long as you keep a supply of oxygen in the blood. That is, people are now aware of the so-called "header for" just put important blood vessel, the plugs in modern medicine is not difficult. But to have independent life, is no easy job! if "head of" the survival of future generations depends on respiratory machine, pacemaker maintained, then the operation will have no significance.

The so-called success of "head of" minimum patients can be spontaneous breathing, heartbeat, even independent independently. But human command central respiratory and heart and not in the brain, while in the medulla oblongata, simple understanding was high in the neck, that is, we often see on television, which was a hit in the neck, can be collapsed in directly to the site. "Head of" at least to wrap to the medulla oblongata, current knowledge of the medical profession is fibers within the medulla oblongata cannot be regenerated. Sun Dr, is like a tree, the branches can fold a long, tree trunks to cut off there is no way. The medulla is the animal, the old hub also controls the animal body all original reflection activities, etc., on which more in-depth and specific research is still ongoing.

Prospects for peripheral nerve surgery to repair just around the corner, as "head of" kindling hope

"Head of" distance we are still very far away, for accidents occurring in patients with nerve damage, faults in the current medical standards can solve the problem?, Beijing, China-Japan friendship hospital neurosurgery to Professor of ice told reporters that in previous General view is that there is a tendency of the nerve is a nerve injury cannot repair, but with the development of medical science, conquer peripheral nerve repair is already within reach. What is peripheral nerve? that is in addition to the brain and spinal cord nerves, the remaining parts of the body belongs to the peripheral nerves. The Professor himself was devoted to the study of "Chitosan catheter bridge peripheral nerve", in short, it is when the peripheral nerve injury, in the context of 2 cm, the closer the better, of course, hollow with a small pipe to rupture

Neural ends, through drugs cause nerve regeneration.

The study is already in rats, monkeys, and other animal experiments successfully, you have to enter the human clinical trial stage. Can doctors face "head of the nerve centres of injury" or helpless, because the nerve centers more more sensitive than nerve, it's not like the peripheral nerves outside a layer coated, peripheral nerve provides a layer of protective sleeve. And so-called "header for" success, no doubt is to resolve cervical spinal neural connections, re-growth. The Professor of ice in the development of modern medicine, many of which may not be realized.

Expert perspectives

Tsinghua second affiliated hospital neurosurgery Director Chan Kwok-keung:

Current medical standards, references to "head for" it remains to be questionable, at least it from our scientific level is still very far away. People in the face "of the head of" the first direct question is ethical problems, first of all, there are more of a donor? at least in China of the medical profession, unheard of. If so, assuming that the "head of" final operation succeeds, then let the emotional brain control to dominate a strange body express their feelings, as a doctor, I think it's hard to imagine!

Tsinghua University, Institute for brain disease: Sun ZhaoHui

Due to the current international yet "head" of the actual surgery, according to current scientific and theoretical basis, if you really just "heads" that can guess a postoperative patients can only rely on the machine to sustain life, instead of independent life, is to change what's the point?
