In 1951, a young mother of five named Henrietta Lacks visited The Johns Hopkins Hospital. Upon     1     (care) examination, the famous doctor Howard Jones discovered a large cervical tumor (宫颈肿瘤).

A small number of her cancer cells     2     (collect) during a medical test were sent to Dr. George Gey’s nearby lab. For years, Dr. Gey, a well-known cancer and virus researcher, had been collecting cells from all patients     3     came to The Johns Hopkins Hospital with cervical cancer, regardless of     4     (they) race or socioeconomic position, but each cell    5     (rapid) died in Dr. Gey’s lab. What Dr. Gey soon discovered     6     (be) that Mrs. Lacks’ cells were unlike any of the others he had ever seen: where other cells would die, Mrs. Lacks’ cells doubled every 20 to 24 hours.

Today, these incredible cells, named “HeLa” cells, are used for     7     (study) the effects of drugs and viruses       8     the growth of cancer cells without experimenting on humans. Scientists use “HeLa” cells to test the effects of radiation (辐射), to study the human genome, and to learn more about how viruses work. These cells also played     9     important role in the     10     (develop) of the polio vaccine (小儿麻痹症疫苗).

4 . A medical emergency can happen anywhere at any time. Taking a brief moment to seek help is often the best first response. But before an ambulance can get to the scene, the immediate first aid attendance to anyone who is injured seriously makes a difference between life and death.

6 . While some Chinese specialists suggest abolishing traditional Chinese medicine (TCM), foreign pharmaceutical (制药的) institutions and industries are pursuing them. Of the global herbal (药草的) medicine sales volume, the Chinese mainland accounts for only 2 percent and Japan has the lion’s share of the market, far ahead of other countries. More than 100 countries and regions around the world have set up TCM institutions, with the United States, Europe, Japan and South Korea spending millions of dollars in research and developing medicine. The UK-based pharmaceutical giant GlaxoSmithKline announced its first TCM medicine research and development program, which targets not just the Chinese market, but the global one as well.

“TCM is a well-built medical science based on thousands of years of clinical practices. It shows great promise treating complicated conditions that the single-target Western medicine has failed to handle,” says Zang Jingwu, senior vice-president and head of GlaxoSmithKline’s R&D in China. “Our focus is to transform TCM from an experience-based practice to evidence-based medicines through innovation,” he says.

Currently, a 10-person team in Shanghai is in charge of the program. However, TCM is different from Western medicine, so great innovation is required to combine the two sciences. In fact, many in Western medicine circles have recognized the importance of TCM, but the problem is how to prove and develop that. TCM is developed through practical experience and improvement of herbs but many people in the West don’t trust that. TCM, particularly herbal products, are largely available in the US and Europe, but questions like how to prove their effectiveness in the context of Western medicine and how to best use them remain unanswered.

Zhang Lingping, director of the international cooperation department of the Beijing University of Chinese Medicine, welcomed the emerging trend. “Their increasing interest shows Western medicine circles have begun to learn about the time-honored medical science, which originated in China,” she says.
