[简答题]Though it has been used in China to treat pain for thousands of years, acupuncture still makes many doctors uneasy, especially in the West. 1. The treatment is based on the idea that needles inserted at specific points can correct a pain-producing imbalance in two bodily forces—the yin and the yang. Dr. Bruce Pomeranz, a University of Toronto neurophysiologist, has a different explanation: acupucture may stimulate the release of the body’s own natural painkillers—endorphins—which act something like morphine (吗啡).
Seven years ago social worker Gwenn Chriss was told she had lupus (狼疮). Once able to swim a mile, she could barely swim across the pool. She tried all sorts of pills, but her pain only got worse.
Desperate, she went to an acupuncturist who inserted about a dozen stainless steel needles at points on her legs, arms and ears. Slowly, Chriss began to recover. Within six months she was swimming again.

PAIN
1 Virtually all animals experience pain. Pain is a distress call from the body signaling some damaging stimulus or internal disorder. It is one of the most important sensations because it is translated into a negative reaction, such as withdrawal from danger. Rare individuals who are born without the ability to feel pain may die from such conditions as a ruptured appendix because they are unaware of the danger.
2 Pain receptors are unspecialized nerve fiber endings that respond to a variety of stimuli signaling real or possible damage to tissues. Some groups of pain receptors respond to specific classes of chemicals released from damaged or inflamed tissue. When pain fibers respond to peptides released by injured cells, this is called slow pain. Fast pain responses--for example, a pinprick or hot or cold stimuli--are a more direct response of the nerve endings to mechanical or thermal stimuli.
