Scientists around the world are working hard to find out effective ways to detect(探测) cancer in the early stage, and a Chinese scientist may have found a quick way of knowing whether malignant(恶性的) tumors exist in a patient's body, with just one drop of blood.
Luo Yongzhang and his team in Tsinghua University's School of Life Sciences in Beijing have successfully invented a test kit of HSP90α for clinical(临床的) use, which can detect several kinds of cancer by studying a drop of human blood.
Malignant tumors in early stages can be cured but once they have spread all over the patient's body, there is no way to save the person's life. However, it's very difficult to detect cancer in its early stages, as patients don't show easily seen symptoms(症状), so to detect cancer early remains a global challenge for scientists.
Back in 1989, scientists found a kind of heat shock proteins (HSP), named HSP90α, which existed in human bodies and could be used as a cancer detecting kit. Scientists around the globe have been working on it since then, and more than 10,000 journals have been published on magazines, yet no one has actually turned their research results into medical products.
However, Luo and his team have been working out the problem since 2009. The team has produced an man-made HSP90α protein and they are able to create the protein, in any quantity, and at any time they wish to. Now, the kit has been certified to enter the Chinese and European markets.
