The rural issues have always received attention from the Chinese government\. Since the opening\-up policy in1 1978\. China\'s agricultural development\, rural areas and the structure of the rural population have undergone tremendous changes\. China has the largest agricultural population in the world and in 2021\, it lifted 770 million rural people out of poverty\, making significant contributions to global poverty reduction efforts\. As a developing country\, China\'s rural social security system has gradually been established after 2000\. As of 2022\, China has a social security system that covers all residents\, which is a remarkable achievement\. However\, the social security benefits for Chinese farmers currently have significant disparities\, especially in retirement and pension benefits compared to urban residents\.\nThis book systematically explores the legal system evolution and improvement of China\'s rural social security system\. especially in terms of the legal protection of farmers\' retirement and pension rights\, from historical\, legal\, and comparative legal perspectives\.

Teachers are one of the important factors in the development of education. Teachers are not only the most valuable asset in educational development, but also the foundation of educational system reform. Therefore, training a high-quality, professional, modern, diversified teaching team has become the focus of China’s educational reform. With the continuous change of our country’s educational concept, the teacher team is increasingly diversified, the key factor to improve their own quality is “professional development”. Teacher professional development is the only way to improve the quality of teaching team; Teacher professional development evaluation is an important measure to promote teacher professional development and improve the quality of education and teaching. At present, with the continuous improvement and reform of China’s education level, the public is gradually turning their attention to primary and secondary education. At the same time, with the changes of society, people’s requirements for education have also changed. The new teaching reform also raises new expectations for their professional development. Primary and secondary school educators can only push themselves to progress and improve their professional abilities. However, in this process, at the level of academic research, there is a relatively lack of academic research on teacher professional development in China at present, and most of it focuses on teachers’ teaching methods. At the teacher group level, many teachers do not know enough about teacher professional development and do not realize the importance of teacher professional development. At the institutional level, the relevant laws and regulations of teacher professional development are still lacking. Therefore, teachers often encounter development bottleneck in the process of professional development and enter the temporary stagnation state of development. Both teachers and school administrators have insufficient understanding of it, and even mistakenly regard it as teacher job burnout. Teachers who are in the bottleneck period for a long time may retire or even leave their beloved jobs. And if we can break through the bottleneck of development, it is possible to achieve qualitative transformation. We must adopt corresponding strategies to help teachers break through the bottleneck of professional development and promote their sustainable development. Therefore, it is more necessary for us educators to timely pay attention to their own growth, perspective the way of teachers’ professional development by examining teachers’ professional identity,attach importance to the value of action research, truly understand the value and significance of teachers’ profession,the limited time and level, there are inevitably omissions in the book, please criticize and correct the majority of readers.

With the development of medical science, the diagnosis and treatment technology of neurosurgery has made great progress. The particularity of nerve tissue in anatomy and physiology requires us to make not only the localization diagnosis, but also the qualitative diagnosis; It not only needs special surgical operations such as cutting, hemostasis and repair, but also needs solid theoretical foundation and diagnosis and treatment skills. At present, there are still many complex problems in neurosurgery, which have become prominent problems affecting human health, population quality and quality of life. Cerebrovascular disease is a common and major disease threatening human health in the world. With the development of modern society, although medical science continues to progress and various diagnosis and treatment technologies continue to innovate, there are still a large number of critically ill patients in this professional field, and the mortality and disability rates are still high. Therefore, the developed countries all over the world attach great importance to the diagnosis and treatment of cerebrovascular disease, and our government also attaches great importance to the research in this field. The rapid development of neurosurgery in hospitals at all levels, the maturity and popularization of DSA and CT angiography, and the establishment and operation of professional intensive care unit will bring strong technology and facilities guarantee for the treatment of such patients.Cerebrovascular disease is one of the common diseases that endanger people's health. It has a high incidence rate and disability rate, which causes great burden to patients and even to society. Therefore, the prevention, treatment, etiology and pathogenesis of cerebrovascular should be popularized and improved. The diagnosis and treatment of cerebrovascular disease is an indispensable and important aspect in neurosurgery. The patients with cerebrovascular disease are diverse and complex. In the treatment process, multi-disciplinary knowledge and multidisciplinary cooperation are needed, including the treatment of basic metabolism, treatment of intracranial hypertension, treatment of cerebrovascular disease, support of respiratory function, monitoring of cardiopulmonary function, and various surgical operations. To save the lives of patients and further improve the quality of life is the goal of our treatment. Our country has a solid foundation in this field of clinical and research, and has accumulated a lot of clinical experience. However, compared with advanced countries, the utilization of resources is not enough, the close cooperation between multi disciplines is not mature enough, and the academic atmosphere of clinical research is not active enough. All these need to be further improved

Allergy is a systemic disease characterized by inflammation of organs or tissues exposed to the environment (allergens), such as asthma, rhinitis, rhinoconjunctivitis in the respiratory system, dermatitis or urticaria in the skin; It causes vomiting, diarrhea and abdominal pain in the digestive system. Allergic patients may have symptoms in one organ, or multiple organs may be affected at the same time. Symptoms range from mild rhinitis, dermatitis, gastrointestinal discomfort to lifethreatening anaphylactic shock. Rhinoconjunctivitis allergic diseases have become a major chronic disease threatening human health after cardiovascular, cerebrovascular diseases, tumors, chronic respiratory diseases, diabetes and metabolic diseases, mental disorders. Allergic diseases involve multiple systems and organs throughout the body, and are affected by many factors such as environment, heredity, allergens. The high incidence rate and the impact on human health have attracted wide international attention. Allergic diseases will become one of the most common global diseases in the 21st century, affecting 1 / 4 of the global population conservatively. In fact, allergic diseases were not common more than 100 years ago, but increased rapidly in the last 20 or 30 years. It is obvious that genetic factors can not be taken as the whole cause of the outbreak of allergic diseases. Environmental factors, dietary structure, intestinal microorganisms, antibiotics and pollution are the influencing factors. As a chronic disease, allergic disease has not been paid attention to by doctors and patients for a long time in the past. Many patients have not received timely diagnosis and effective treatment. With the development of the natural process of the disease itself, the quality of life of patients has been seriously affected. The World Allergy Organization recommends a four in one management mode for allergic diseases, that is, avoiding contact with allergens, symptomatic drug treatment, allergen specific immunotherapy and doctor-patient education. It can be seen that doctor-patient education plays an important role in the prevention and treatment of allergic diseases.
