During the 40 years when I was a pediatric surgeon, I saw 95% mortality (必死的)rates for congenital defects( 先天缺陷) transformed into 95% survival rates because of what surgery can accomplish. As U.S. Surgeon General, I saw effective prevention and treatment techniques beat back the mortality from tobacco use and AIDS. And now, as an 85-year-old, my life has been prolonged（延长）and kept active by wonder drugs unknown to my parents. So it's been somewhat surprising in this era of triumph（成功）for modern medicine to see the rapid growth of alternative/complementary（替代物，补充物）medicine, which is used by as many as one in three Americans. Although most of those still refrain from informing their regular physicians about that use, there is a growing tendency among physicians to acknowledge and even embrace （拥抱）certain forms of alternative/complementary medicine.Changes in the use of the terms "alternative" and "complementary" suggest the shape of this shift. At first, it was called simply "alternative medicine," reflecting a dissatisfaction with regular medicine as well as a cultural rebellion（反叛，不服从）against the biomedical community. In more recent years, several studies indicate that there has been a shift from "alternative" therapies to "complementary" therapies, adopted not in opposition to regular medicine but in alliance with it. And increasingly those who use one of the many forms of complementary medicine are not treating a specific medical problem. Rather, they are practicing prevention in ways they find more congruent with their philosophical values or lifestyle.Now I think we may be seeing another refinement, one that is taking us from "complementary"to "safe and effective." For some people, the appeal of alternative medicine lies in its alternative stance, and as some of these therapies enter the mainstream, some of these individuals may seek other alternative practices. But more and more Americans are demanding greater certainty from alternative or complementary products as an increasing number of press reports document health problems resulting from certain natural products and complementary practices. Thus, the baby-boom health consciousness that led to the resurgence of alternative/complementary medicine now turns toward solutions that rest more heavily on science. We went through a somewhat similar passage a century ago, when dissatisfaction with regular medicine and a growing consumer market in health products led to the widespread use of a variety of nostrums and patent medicines。
