Paragraph 0018-0019, (2020/05/30)
The invention relates to a novel synthetic method of camphorquinone, which is a method for preparing camphorquinone from camphor in the presence of a catalyst. The invention further provides a methodfor preparing camphorquinone, which can effectively reduce the toxicity of the used catalyst and reflect the harm to the environment, and ensures a high yield of the reaction while simplifying the process flow. According to the method, clean energy microwave irradiation instead of conventional energy is utilized, so that the pollution of the reaction to the environment is greatly reduced while thereaction yield is ensured, and the purpose of green chemistry is met.
Selectively polymerizable compositions and methods of use in vivo

Otologic materials and methods are provided. For example, a cell-adhesive, biodegradable hydrogel scaffold loaded with time-released drugs for repairing chronic tympanic membrane perforations is disclosed, methods of making same and administering same are provided. This hydrogel may promote vascular in-growth and epithelial cell growth of the tympanic membrane with the purpose of closing the perforation and providing a barrier between the external and middle ear. The hydrogel is initially a liquid polymer that only gels upon exposure to specific conditions, such as exposure to light. This scaffold may simultaneously induce repair of the tympanic membrane while preventing or alleviating middle ear infection, thus filling a void in current tympanic membrane perforation therapies.
