随着我国计划生育工作的深入开展,向制药工作者提出了一个艰巨的任务,即如何贯彻“少生、优生、优育”,解决一个增强国民体质的问题。目前,孕妇普遍存在贫血、缺钙及新生儿体重偏轻的现象。智力低下是医学中的一个难题。我国人群中约有2.2％的人智力低下,其中轻者占2％,严重者占0.2％,已成为社会的负担和国家的累赘。 With the deepening of family planning work in our country, the pharmaceutical workers have posed a daunting task of how to carry out the policy of “giving birth to fewer children, eugenics and fertility,” and resolving a problem of enhancing the constitution of the people. At present, pregnant women are generally anemic, calcium deficiency and neonatal weight-loss phenomenon. Mental retardation is a problem in medicine. About 2.2% of our population is mentally retarded, of whom 2% are light and 0.2% are serious, which has become a burden on society and a burden on the country.
