"At the same time," he added, "in developing countries today, malnutrition is the cause of 174 million children under five years of age being{{U}} (51) {{/U}}, and 230 million being stunted(阻碍)in their growth.

单选题U. S. to Start $ 3.2 Billion Child Health Study in January "A study that will cost $ 3.2 billion and last more than two decades to track the health of 100,000 U. S. children from before birth to age 21 will be launched in January. " U. S. health officials said on Friday. Officials from the U. S. government's National Institutes of Health said they hope the study, to be conducted at 105 locations throughout the United States, can help identify early-life influences that affect later development, with the goal of learning new ways to treat or prevent illness. The study will examine hereditary and environmental factors such as exposure to certain chemicals that affect health. Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air, water, dust and materials used to construct their residences, the NIH said. Officials said more than $ 200 million has been spent already and the study is projected to cost $ 3.2 billion. "We anticipate that in the long term , what we learn from the study will result in a significant savings in the nation's health care costs. " Dr. Duane Alexander, who heads the NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development, told reporters. The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up pregnant women whose babies will then be followed to age 21. Some of the early findings will be about factors behind pre-term birth, which has become more common in recent years, according to Dr. Peter Scheidt of the NIH, who heads the study. The people taking part will be from rural, urban and suburban areas, from all income and educational levels and from all racial groups, the NIH said.

单选题Medical Education In 18th-century colonial America, those who wanted to become physicians either learned as personal students from established professionals or went abroad to study in the traditional schools of London, Paris, and Edinburgh. Medicine was first taught formally by specialists at the University of Pennsylvania, beginning in 1765, and in 1767 at King"s College (now Columbia University), the first institution in the colonies to give the degree of doctor of medicine. Following the American Revolution, the Columbia medical faculty (formerly of King"s College) was combined with the College of Physicians and Surgeons, chartered in 1809, which survives as a division of Columbia University. In 1893 the Johns Hopkins Medical School required all applicants to have a college degree and was the first to afford its students the opportunity to further their training in an attached teaching hospital. The growth of medical schools attached with established institutions of learning went together with the development of proprietary (私营的) schools of medicine run for personal profit, most of which had low standards and poor facilities. In 1910 Abraham Flexner, the American education reformer, wrote Medical Education in the United States and Canada, exposing the poor conditions of most proprietary schools. Subsequently, the American Medical Association (AMA) and the Association of American Medical Colleges (AAMC) laid down standards for course content, qualifications of teachers, laboratory facilities, connection with teaching hospitals, and licensing of medical practitioners (开业医师) that survive to this day. By the late 1980s the U. S. and Canada had 142 4-year medical colleges recognized by the Liaison (联络) Committee on Medical Education to offer the M. D. degree; during the 1987-1988 academic year, 47,262 men and 25,686 women entered these colleges and an estimated 11,752men and 5,958 women were graduated. Graduates, after a year of internship (实习期), receive licenses to practice if they pass an examination given either by a state board or by the National Board of Medical Examiners.
