Give examples to illustrate the achievements of modern science and technology in medicine.

The continuous improvement of medical devices such as defibrillation, artificial pacemakers and artificial respirators has significantly improved the therapeutic effect of some diseases. Development of diagnostic technology. X-ray was discovered by W.C. Roentgen in 1895, and X-ray diagnosis became an important means of clinical medicine in the early 20th century.

At first, it was used to observe the state of bones. 1906 gastrointestinal movements were examined with bismuth paste, and then X-rays were taken with barium meal and iodized oil. Since then, important diagnostic techniques have been developed: electrocardiogram (1903), syphilis serum reaction (1906), cerebral angiography (191), cardiac catheterization (1929) and cardiac catheterization.

In the late 1950s, biomedical engineering became an independent discipline. In addition to artificial organs, it also studied artificial joints, artificial limbs and artificial senses. In 1960s, laser was used in clinic. 1960 the first laser was first used in ophthalmology.

Science and technology determine the nature of advanced productive forces. Productivity is a complex system composed of laborers, labor tools and labor objects, as well as the organization and management of labor process. The advanced nature of specific productive forces in a specific era should be reflected by the advanced nature of each element in the system. The transformation of laborers from "physical strength" to "knowledge" marks the improvement of the advanced level of productive forces.

Secondly, science and technology determine the evolution direction of advanced productive forces. Before the 20th century, the interactive relationship between science, technology and production often developed in the order of production, technology and science, that is, the practice of production and technology laid the foundation for the formation of scientific theory. At present, technology is obviously ahead of schedule.

Biotechnology developed from molecular biology, biochemistry, microbiology and genetics is widely used in industry, agriculture, medicine and health, food industry and other fields, which makes productivity develop to more and more advanced fields.

Extended data

Science and technology are the first factor of modern productivity development and economic growth. In the past, the development of productive forces and economic growth mainly depended on the input of labor, capital and natural resources. In modern society, with the advent of the era of knowledge economy, science, technology and intellectual resources have increasingly become decisive factors in the development of productive forces and economic growth, which mainly depend on the power of science and technology. This is especially true from the practice of economic development in developed countries.

The progress of modern science and technology plays a leading role in the development of productive forces. /kloc-the second technological revolution at the end of 0/9 was a turning point in the relationship between science and technology and production. Prior to this, the relationship between production and science and technology was mainly manifested in that the development of production promoted technological progress, which in turn promoted the development of science.
