China Exclusive: Scientists use light beams to prick mystery of acupuncture
SHANGHAI, Feb. 1 (Xinhua) -- Chinese scientists are using the country's most expensive ever science project, a light-emitting synchrotron, to solve the mystery of acupuncture points.
The Shanghai-based synchrotron, which uses super-powerful X-rays to resolve the structure of matter down to the level of atoms, has detected evidence that acupuncture points differ from other parts of the body.
pandora charms Zhang Xinyi, deputy director with the synchrotron radiation research center at Fudan University, said, "We are trying to figure out the three-dimensional structure of the acupuncture points with the light resources."
Many foreigners thought the acu-therapy effective, but doubted whether acupuncture points did exist, he said.
X-ray beams emitted by the Shanghai Synchrotron Radiation Facility(SSRF) are 100 million times brighter, and 10,000 times more intense than the beam produced by a standard X-ray machine, said Xiao Tiqiao, head of the construction of SSRF's beamlines.
Zhang and his team's previous study of acupuncture points involved the examination of human and rabbit tissue samples at the Beijing Synchrotron Radiation Facility.
"In an experiment on rabbit tissue, we have found that at acupuncture point regions there exists the accumulation of micro- vessels. But the images taken in the surrounding tissue out of the acupuncture points do not show such structures," said Zhang and his colleagues in the paper, "Imaging Study on Acupuncture Points" for the 9th International Conference on X-Ray Microscopy in 2008.
The micro-vessels of a long blood vessel and some fine branches were observed at the acupuncture point of Sanyinjiao acupuncture point on the rabbit's lower leg, and a short cluster of vessels at the Tianshu point on the belly. The micro-vessel gathering have also been detected at the Neiguan point on the foreleg and Zusanli on the lower leg.
They also replica bag wholesale determined that the contents of calcium, zinc, iron and copper were significantly higher at three of four human acupuncture points examined. The Jianshi (forearm), Tiaokou and Xiajuxu (both on the lower leg) points had higher contents than in the surrounding tissues, although the finding was not confirmed at the Ximen (forearm) point.
Their paper suggested these structures had a link with the function of acupuncture points and played an important role in acupuncture treatments.
The SSRF, designed to boost China's capacity in scientific research, concluded a nine-month trial operation last month.
The light sources of the SSRF could emit different electromagnetic waves tailored to scientific experiments in many fields such as life sciences, biochemical projects and new materials, Xiao said.
During the trial operation, the light sources helped in the treatment of fatal cancers, a task led by the scholars with the Med- X Institute of the Shanghai Jiao Tong University.
"The beamlines are just like super microscopes. They can contribute to the treatment of early-stage cancers by detecting the tumor cells that might be overlooked by the X-ray at hospital," Xiao said.
Other researchers used the super X-rays to shed light on the treatment of brain diseases, and they have already yielded breakthroughs.
