The historical background of eastern and western cultures is the soil for the formation and development of Chinese and western medicine. Zhang Zhongjing and Galen, two great medical masters of the East and the West in the 2nd century A.D., inherited different academic ideas, created different medical paradigms, developed and perfected different theoretical systems, and made Chinese and Western medicine take two completely different development paths.
Before Treatise on Febrile Diseases written by Zhang Zhongjing, a physician in the Han Dynasty, there were classic medical classics such as Neijing, Difficult Classic and Herbal Classic. Zhang Zhongjing summarized the medical achievements before the Han Dynasty, inherited the basic theories such as Neijing and rich medical knowledge, and combined with his own clinical practice, wrote Treatise on Exogenous Febrile Diseases. Its contribution lies in the establishment of the theoretical system of TCM syndrome differentiation and treatment, which has laid a solid foundation for the development of TCM clinical medicine in later generations.
In the west, Galen lived in the Roman Empire under the rule of Antony and his son. At that time, the prosperity of the Roman Empire provided a reliable political, economic, scientific and cultural guarantee for Galen's medical achievements and the prosperity of western medicine. Galen inherited Hippocrates' academic thoughts and wrote more than 200 books. Among the 83 existing works, the contents involve anatomy, physiology, pathology, health science, medicine, research on Hippocrates' collected works, philosophy, linguistics, logic, mathematics, history and law. Advocating empirical medicine, his scientific methodology has the characteristics of attaching importance to experiment, disease localization, formal logic and deduction, which has a far-reaching impact on the development of western medicine in later generations.
Under the guidance of Zhang Zhongjing and Galen's completely contradictory medical paradigm, Chinese and western medicine began to go their separate ways. Under the background that China culture emphasizes "neutralization", there is a relaxed atmosphere of "all rivers run into the sea" in academic circles. There have been wonderful presentations of academic schools, such as the dispute between cold and warm plague and the difference between classics and prescriptions. Traditional Chinese medicine develops vigorously according to Zhang Zhongjing's thinking paradigm. With the progress of science and the development of society, especially the development of medical practice, the original theory of traditional Chinese medicine has been unable to explain new scientific facts. Therefore, medical theory must be constantly innovated to meet the needs of society, which prompted Chinese medicine to enter the stage of all-round development after the Han Dynasty. This stage includes four stages: the comprehensive compilation and deepening development of TCM theory and the enrichment and improvement of clinical syndrome differentiation system. For example, Lou Ying's Outline of Medicine in Ming Dynasty and Wang Kentang's Criterion of Syndrome Differentiation and Treatment, Janice's Golden Mirror of Medical Records in Qing Dynasty and Chen Menglei's Collection of Ancient and Modern Books and Complete Collection of Medical Department, etc. Wang Qingren's book Yi Lin Nun pays attention to empirical research, corrects some mistakes about anatomical knowledge in ancient medical books, affirms "brain dominates thinking" and develops the theory of blood stasis. The formation and development of febrile diseases indicate the innovation and breakthrough of TCM theory. Wu Youxing wrote Treatise on Febrile Diseases, Ye wrote Treatise on Febrile Diseases and Wu Jutong wrote Treatise on Febrile Diseases. In pharmacological research, Li Shizhen wrote Compendium of Materia Medica, summarizing the results of pharmacological research in China before16th century.
With the demise of the Western Roman Empire, Western medicine gradually entered the Millennium darkness of the Middle Ages, science became the handmaiden of theology, and priests replaced doctors. From the13rd century, vision gradually recovered, and it was not until the15th century that it broke through the feudal religious barriers and developed rapidly. Vesaliua initiated modern anatomy and anatomical physiology; 173 1 year, Morgan, Italy founded pathological anatomy; 1855, cytopathology founded by Wilshaw, Germany; At the same time, western scientific methodology plays a guiding role in the development of medicine. The empirical method based on experiment (observation experiment and comparative analysis) completely breaks away from scholasticism in medical research, and relies on various technical means and methods provided by natural sciences to cultivate medical scientists' scientific consciousness, endow them with the natural science attributes of medicine, make them get rid of the fantasy of speculative reasoning and realize the experimental science of biomedical model. At this point, Chinese medicine can not be compared with western medicine in the field of empirical medicine. However, compared with western medicine, the advantages of traditional Chinese medicine lie in starting from the macro, focusing on the whole, emphasizing the relationship between local and local, local and whole, attaching importance to syndrome differentiation and classification, and advocating the individualized diagnosis and treatment strategy of "treating diseases due to three factors".

6. The diversity of agricultural production objects and the complexity of production conditions determine that agricultural science has a wide range and many categories, some of which focus on basic theory and some on applied technology. With the mutual penetration of related disciplines, new research fields emerge one after another, and the scope of disciplines is still expanding.
Judging from the current situation, agricultural science can be roughly divided into five categories, with several disciplines and their branches in each category, except forestry and aquaculture, which are relatively independent subject systems.
Agricultural environmentology Agricultural environment is the material condition for the survival and development of agricultural organisms, and it also includes organic environment in a broad sense, that is, other biological factors other than agricultural organisms, but it also often refers to inorganic environmental conditions such as light, temperature, moisture, atmosphere and soil. Agricultural environmental science mainly studies the occurrence and development, composition and structure, regulation, transformation and utilization of agricultural biological environment. At present, the more mature branches are pedology, agrometeorology and so on. Agricultural engineering, including farmland water conservancy science, is also a part of agricultural environmental science, but it has developed into an independent discipline.
Crop production is also called agronomy or agronomy. Its research objects include not only field crops, but also horticultural crops such as fruit trees, vegetables and flowers. Crop production is a complex process affected by many factors. The comprehensiveness of crop production often makes it difficult to completely separate it from some disciplines of natural science, but in practice, some relatively systematic disciplines have also developed.
The role of crop breeding and crop cultivation is to improve the yield, quality and stress resistance of crops, and even change the configuration of plants and plant organs to meet the needs of cultivation, packaging, storage and transportation. The role of plant pathology, agricultural entomology, weed science and pesticide science is to minimize the loss of crop production.
With the deepening of research, on the one hand, these disciplines are further differentiated, such as plant pathology, and further subdivided into plant pathogenic mycology, plant bacteriology, plant virology, plant nematology, plant immunology, etc. On the other hand, they tend to be integrated, such as applying integrated control in pest control and combining plant protection measures with breeding and cultivation measures. This, in turn, has led to increasing attention to ecology and system science in agricultural production.
Animal husbandry science is a science that serves to economically increase the production of high-quality livestock, poultry and livestock products such as meat, milk, eggs and fur. Among them, the development of livestock breeding and the application of heterosis utilization, artificial insemination and embryo transfer have greatly accelerated the breeding speed of improved livestock and poultry. The progress of livestock nutrition has revealed more and more the nutritional requirements of various livestock in different situations and the contents of various nutritional elements in many feeds.
The application of electronic computing technology in the study of the best feed scheme has effectively promoted the development of feed industry and the mechanization and industrialization of livestock and poultry production, improved feeding density and labor productivity, shortened production cycle and made products more standardized.
Veterinary medicine is an independent discipline, and many countries have not included it in the category of agricultural science. However, due to its close relationship with animal husbandry science, they are still compared in many cases.
The importance of veterinary drugs lies in that it makes it possible to improve the environmental sanitation conditions of animal husbandry, prevent and treat livestock and poultry diseases, and thus reduce the economic losses caused by diseases. With the industrialization and intensification of animal husbandry production, the role of veterinary drugs will be more prominent. Veterinary branches mainly include veterinary microbiology, veterinary parasitology, infectious diseases of livestock, veterinary internal medicine, veterinary surgery, veterinary obstetrics and veterinary pharmacology.
Agricultural engineering science is an applied science combining modern agricultural biology with modern engineering. It comprehensively uses all kinds of engineering knowledge to improve the technical and environmental conditions of agricultural production (including processing, storage and transportation of agricultural products) and sometimes to improve the living conditions of farmers.
Early agricultural engineering mainly studied and solved the problems related to the design, manufacture, use management and sales service of agricultural machinery. Now the research scope has been extended to agricultural architecture and environmental control, water and soil resources, rural energy development and utilization. Agricultural system engineering takes agricultural system as the object, and is applied to agricultural layout, aquatic ecosystem, crop population physiology and integrated pest control, which will provide an important means for systematic, quantitative and optimal research of agricultural production.
Agricultural economic science takes the relations of production and the law of productivity movement in agriculture as the object, and studies various social relations in the process of production, exchange, distribution and consumption of agricultural products, as well as the utilization and combination of various elements of agricultural productivity, the proportional relationship and layout of various production departments within agriculture, and the economic effects of agricultural production technical measures. Some of them have formed relatively independent branches, such as agricultural production economics and management economics. Study time: four years

2. Medicine: in the definition of human health, the science of dealing with problems related to the good state of human physiology aims at treating and preventing physiological diseases and improving human physiological health. Refers to the educational activities to train medical and health personnel purposefully, planned and organized according to social needs.

Therefore, as long as you find the right position, you will become more and more popular.
Modern medicine
Modern science and technology not only studies things and phenomena, but also studies the change and development process of things and phenomena and the relationship between things. From the science of "sorting materials" to a closely integrated system.
Modern medicine experienced the foundation of 16 ~ 17 century, the systematic classification of 18 century and the great development of 19 century. The 20th century was closely combined with modern science and technology and developed into modern medicine. The characteristics of medicine in the 20th century are, on the one hand, microscopic development, such as molecular biology; On the one hand, it is macro development. From the macro-development, it can be divided into two types: first, people realize that people themselves are a whole; The second is to study people as a whole closely interacting with the natural environment and social environment. Since the 20th century, the most outstanding achievement of basic medicine is the development of basic theory, which has effectively promoted clinical medicine and preventive medicine. Effective means to treat and prevent diseases only began to appear in the 20th century. The main reason for the development of medicine in the 20th century is the progress of natural science. The cross-integration of disciplines and specialties is one of the characteristics of modern medicine.
The transformation of medical model
Due to the progress of natural science, medicine in the 20th century was based on experiments and made unprecedented progress in technology. Later, people saw that it was very limited to consider health and disease only from the biological point of view. 1977, American medical scientist g l Engel (1913 ~) put forward the idea of bio-psychological-social medical model, that is, to comprehensively examine human health and diseases from three aspects of biology, psychology and sociology, so as to make up for the deficiency of previous research from the biological point of view and have great significance for the development of medical and health undertakings in the future.
In a word, medicine has made great progress since the 20th century. At the research level, molecular medicine and system medicine go hand in hand, developing from micro to macro. In the discipline system, the separation of disciplines and the cross-integration between disciplines go hand in hand. The internationalization trend of medical research is increasingly obvious; The achievement of scientific achievements is no longer just the result of personal efforts.
Future medicine
Whether Chinese medicine or western medicine, from birth to now, the main function is to treat diseases. At the end of the 20th century, the final conclusion of global medical discussion is that the best medicine is not the medicine to cure diseases, but the medicine to keep people from getting sick. Therefore, we believe that the future medicine should be scientific prevention, and scientific prevention is to make people less sick and not sick. So what is a scientific treatment? It is to predict physical, mental and intellectual diseases and distinguish which foods are caused by sick people and those who are not sick. Individualized scientific dietotherapy can achieve the purpose of treating different diseases at the same time through food supplement and food restriction. Applicable people: pre-disease prevention, early detection of diseases, and rehabilitation of serious diseases. Critical illness needs Chinese medicine, western medicine, surgery, radiotherapy and chemotherapy. And the future medicine, that is, scientific disease prevention, is to use green therapy and balanced diet to prevent and treat mental and physical diseases. Human beings are created by nature, and food feeds them. Any food in the world has medicinal effects. Long-term partial eclipse means that the diet structure is unscientific and unreasonable, leading to countless diseases and even death. The World Health Organization has put forward four cornerstones of health: balanced nutrition, moderate exercise, adequate sleep, smoking cessation and alcohol restriction.

6. Agricultural resources:
There were 9 papers * * * 1 14 in early agronomy, which were specifically listed as "farmers" in Hanshu Yiwenzhi. Basically, there are no agricultural works in the Six Kingdoms period, and the only pre-Qin documents we have seen are Shang Nong, Ren Di, Lun Tu and Shi Shi in Lv Chunqiu.
Four books, such as Lu Chunqiu Shangnong, are the most systematic agricultural works in the pre-Qin period, and their contents are roughly taken from Postscript Nongshu. Hou Ji's "Agricultural Book" should be a work in the early Warring States period. There is no mention of this agricultural book in the records of Han Shu Literature and Art, which shows that it has long been lost. Fortunately, this part was preserved in Lv Chunqiu. Among them, "de-agriculturalization" is about agricultural policy; Ren Di, Debate on Soil and Judge Time are all about agricultural technology.
We can also see the agricultural books of the Han Dynasty, including The Great Victory Book and The Four People's Moon Order.
The formation of modern agricultural science is only 100 years old, but the process of its occurrence and development has a long history. The formation of ancient astronomy, phenology, calendar, measurement and other knowledge is actually related to the early agricultural production practice of human beings, and it is the reflection of people's exploration results on agricultural production conditions, seasonal changes and land use patterns at that time.
Later, people changed from trying to understand the agricultural environment to trying to change the environmental conditions and agricultural production objects themselves, which promoted the gradual systematization of knowledge in soil cultivation, fertilization, irrigation, crop variety selection and cultivation, livestock breeding and so on. China ancient agricultural books, with their vast space, provide strong evidence for the brilliant achievements of ancient agricultural research.
/kloc-After the middle of the 0/9th century, the research results and experimental methods of natural sciences such as biology, chemistry, physiology, genetics, entomology, microbiology, pedology and meteorology were gradually applied to agriculture, which promoted the qualitative change of agricultural research from the empirical level to modern agricultural science. The publication of Justus von Liebig's classic book "Application of Organic Chemistry in Agriculture and Physiology" from 65438 to 0840 is generally considered to mark the beginning of the development of modern agricultural science system.
Since then, various agricultural sciences based on experiments have been formed. The application of agricultural chemistry in crop cultivation led to the establishment of fertilizer industry, the development of plant physiology and plant nutrition, and the crop cultivation technology became more scientific. The introduction of Mendel's genetic law and genetic theory led to the birth of modern crop breeding. With the application of the principles of biochemistry, physiology, pathology, anatomy and genetics in livestock production, the breeding, breeding, feed science and veterinary medicine of livestock have also developed rapidly.
At the beginning of the 20th century, power machinery, especially internal combustion engines, tractors and other mobile farm tools gradually became popular, which changed the situation of taking animal power as agricultural power and accelerated the process of agricultural mechanization. The resulting agricultural machinery science provides a theoretical basis for continuously improving agricultural productivity.
After the Second World War, the synthetic chemical industry rose, which promoted the research of various pesticides, herbicides and agricultural plastics, and the means of plant protection became more and more perfect. With the development of cytogenetics and molecular genetics, the application research of biotechnology such as genetic engineering in agriculture has begun to achieve results, marking a new revolution in breeding technology. The application of ecological science and system science in agriculture has opened up new ways and fields for the development of agricultural science from a macro perspective.
At the same time, the new research methods provided by nuclear technology, computer, remote sensing and telemetry technology have also made and are making agricultural scientific research more accurate. Due to the progress of agricultural science and technology, agricultural producers can not only improve agricultural labor productivity several times or even dozens of times, but also greatly increase the unit output of various animal and plant products, effectively improve product quality, and greatly reduce losses caused by harmful organisms and unfavorable natural conditions. Agricultural science has become an indispensable part of agricultural productivity and a necessary condition for agricultural modernization and rapid improvement of agricultural production level.
Of course, the improvement of agricultural productivity is not only due to natural science. The development of agricultural economic science has also played a great role in people's more conscious agricultural production according to economic laws, changing and perfecting the production relations in agriculture, rationally organizing agricultural productivity, improving the production, circulation and distribution of agricultural products, and constantly improving economic benefits. Driven by the development of agricultural production, agricultural science is developing continuously in both micro and macro fields. What is particularly striking is that the solution of many agricultural production problems requires multi-disciplinary and multi-professional cooperation, and the trend of agricultural science towards integration on the basis of continuous subdivision is strengthening, thus giving birth to many new disciplines and majors.
For example, regional land management, which serves the comprehensive management of low-and medium-yield areas, is a specialty of "genetic evaluation and utilization" that integrates the knowledge of different disciplines such as genetic breeding, plant pathology and plant physiology to cultivate excellent varieties with high yield, high quality, strong stress resistance and wide adaptability. Research methods are being further accelerated and improved. At the same time, extensive scientific research cooperation and international cooperative research are also developing further.
