National Gold Award!The material of artificial liver is actually derived from the crayfish shell

Wuhan Evening News (Reporter Xie Dongxing) On August 25, the 9th "Chuang Youth" China, co -sponsored by the Communist Youth League Central Committee, Ministry of Human Resources and Social Security, Ministry of Agriculture and Rural Ministry, Ministry of Commerce, National Rural Revitalization Bureau, and Hubei Provincial People's Government The youth innovation and entrepreneurial competition science and technology innovation special competition ended in Wuhan. The "Clinical Application of Natural Polymer Biological Liver Support System" developed by Professor Ye Qi, the Institute of Hepatobiliary Diseases of the Central South Hospital of Wuhan University, won the gold medal of the first competition sorting!

According to the "China Youth Magazine", the special competition of the Chinese Youth Innovation and Entrepreneurship Contest of the China Youth Innovation and Entrepreneurship Contest was the second time to hold an awards conference in Wuhan Donghu High -tech Zone. The competition has tracks such as life and health, future industries, intelligent manufacturing and information technology. In the end, 8 gold awards, 15 silver awards, and 29 bronze awards.

Such a scientific and technological award has just been released, and the aquaculture farmers of Qianjiang are not calm first. On the afternoon of August 27, the "Qianjiang" under Qianjiang Radio and Television quickly followed up and published, and the micro -signal title called "cutting -edge of breeding" was more straightforward -the crayfish shell solved the big problem of patients with liver disease. Those who raise crayfish are going to make a fortune!

The reporter carefully retrieved and found that the source of this gold award came from academician of the Chinese Academy of Sciences and Professor Zhang Lina of Wuhan University.

Among the global rich renewable resources, the volume of cellulose and chitin is the top two, safe and never exhausted. They are extremely stubborn macrons, which are difficult to dissolve and cannot be melted. How to develop and use the world's problems.

According to Hubei Daily, in 1993, Zhang Lina founded the natural polymer and polymer physics research group. In January 2000, she was already a professor at the Department of Chemistry of Wuhan University and began the research of new fiber solvents and materials. This year, she was 60 years old.

She used the first batch of National Natural Science Foundation of China to begin basic research on natural polymer, and put energy into the use of "green" technology to create environmentally friendly new materials through "green" technology. After countless testing, establishment of models and mechanism research, Zhang Lina found that cellulose and chitin can dissolve in mixed solutions of water, urea and sodium hydroxide. Not only are the dissolution speed, the cost of raw materials is cheap, but also the separation of elements is very convenient.

Academician Zhang Lina's team uses them to create a series of new cellulose and chitin silk, film, plastic, hydrogel, microfinance, foam plastic, etc.; Prove that they have excellent performance and biodegradability. After the abandonment of these new materials, it can be completely degraded in rivers, lakes, lakes, lakes, lakes, lakes, lakes, lakes, lakes, lakes, lakes, lakes, lakes, lakes, lakes, lakes, lakes, lakes and soils, which can completely biodegradation, which does not cause environmental pollution, causing high attention and recognition of international counterparts.

Zhang Lina was elected academician of the Chinese Academy of Sciences in 2011. She has the world's first water solvents to dissolve polymer technology, and has opened a new "green" door for biological waste to make new materials. It can be widely used in biomedical and other fields in the future. With this invention, Zhang Lina was awarded the 2011 Andersham Payne Award in the American Chemistry Society. This is the highest award in the field of renewable resources. Zhang Lina became the first Chinese to win the award in half a century.

From then on, natural polymers, which have been regenerated forever, have become the "pockets" of the global scientific community. Based on this, the invention of various new materials is possible.

Associate Professor Zhong Zibiao is a member of the team of Professor Ye Qi, a team of Hepatobiliary Disease Research Institute at the Central South Hospital of Wuhan University. He was originally a doctor of medicine. After work, he chose to study for a PhD in chemistry, and joined the team of Academician Zhang Lina of the Chinese Academy of Sciences.

According to reports, at present, most of the materials for making artificial liver are resin, and the detoxification effect is not ideal. Academician Zhang Lina's green dissolution technology, extract chitin from the hard shrimp and crab shells. The made of the sphere can adsorb heavy metals and waste liquid, which inspired Zhong Zibiao. After experiments, he found that the chitin extracted from the lobster shell also has unique effects in adsorption of toxins. As a biological extract, it has better compatibility and human tissue than resin, and it can accurately absorb toxins such as bilirubin and other toxins, and will not hinder the absorption of normal nutrients such as albumin.

According to the WeChat public account of Zhongnan Hospital of Wuhan University, the natural polymer biological liver developed by Zhong Zibiao's team has completed the process of material development, animal experiments, and safety assessment, and clinical trials will soon be carried out.
