The heart of a 3D print will be "heart" moving? Following the 3D-printed teeth, joints, heart stents and valves, the emerging "printing world" is revolutionizing the future of healthcare . During the two sessions, Ge Junbo, member of the National Committee of the Chinese People's Political Consultative Conference, academician of the Chinese Academy of Sciences, and dean of the Biomedical Research Institute of Fudan University, interviewed Xinhua News Agency to see the possibility of 3D printing technology in the field of heart disease treatment in the future. In July last year, Swiss researchers announced that they have used 3D printing technology to create the world's first flexible heart with a shape, size and function similar to that of a real human heart. So, when can 3D printing be applied to complete organ printing and enter the field of transplantation? "It is not difficult to simply print the structure and shape of the heart. It is difficult to maintain the conduction system of the heart." Ge Junbo said. He said that this is a very complicated project because the heart is made up of different tissue cells. "The self-discipline of the myocardium, the contractile function and persistence of the heart are difficult to achieve in 3D printing in the near future." At present, there is a view in the international medical community that it takes 20 to 30 years, or more, 3D printing technology to achieve a "heart" movement. However, even if the heart of 3D printing is currently only a body, it does not mean that 3D printing can only stay in the "hard state" parts of teeth and bones in the biomedical field. In March of this year, the American academic research team demonstrated a 3D printing technology that can be used to determine which aortic valve replacement program is suitable for patients and to predict surgical complications through personalized modeling. In addition, China’s first high-throughput integrated bio-3D printer was announced in November last year. According to Ge Junbo, this modeling technique is mainly used for preoperative surgery for complex structural heart disease. After the 3D reconstruction of the examined imaging data, personalized 3D printing is performed to simulate the possible conditions during the operation. This technology is currently being applied in Shanghai. He also revealed that the current "heart valve" of 3D printing, due to its shortness of persistence, has not been used in clinical practice at home and abroad, and is still in the experiment. As for the cardiac stent, it has been successfully printed with polylactic acid. The animal test has found that it is safe and effective, and is now undergoing human clinical trials and clinical follow-up. In fact, the use and experimentation of 3D printing technology does not stop at the biomedical field. Worldwide, aerospace, automotive, mold, consumer goods, etc. are also increasingly connected to this technology. Related art is also known as additive manufacturing technology. China has regarded the “additive manufacturing industry†led by 3D printing as an important part of the development of the manufacturing industry. In 2017, the Ministry of Industry and Information Technology and the Department of Development and Reform Commission and other 11 departments issued the "Additive Manufacturing Industry Development Action Plan (2017-2020)", which proposes that by 2020, China's additive manufacturing industry will have an annual sales income of more than 20 billion yuan, with an average annual growth rate of 30%. Above; key core technologies have reached the level of international synchronization. However, there are also some people who worry that in the future, through the means of "3D printing + transplantation", the possibility of human beings fighting chronic diseases will increase greatly. It will become possible to realize "longevity and old age". At that time, human beings may have to face various new societies. Ethical issues. In this regard, Ge Junbo believes that in the field of heart disease treatment, 3D printing technology is still only in the experimental stage. With the development of science, if different tissues and organs of the body can be printed and applied to the clinic, it is necessary to conduct normative and ethical argumentation. (Xinhua News Agency) Natural sweeteners refer to food additives that can sweeten soft drinks. They can be divided into natural sweeteners and synthetic sweeteners according to their sources.

Natural sweeteners are substitutes for sugar. Natural sweeteners considered to be generally safe include stevia, licorice, disodium glycyrrhizinate, tripotassium glycyrrhizinate and trisodium. Natural sweeteners have many uses in the home and in processed foods.
Natural non-nutritive sweeteners are increasingly paid attention to, is the development trend of sweeteners, WHO pointed out that diabetes patients have reached more than 50 million, more than a quarter of the American people require low-calorie food. In sucrose substitutes, the United States mainly uses aspartame, up to more than 90%, Japan mainly uses stevia glycoside, and Europeans are more interested in AK sugar (acesulfames). All three non-nutritive sweeteners are available in China.
