Abstract: Disclosed is a recycled polystyrene (PS) plastic film prepared from 100% of a waste PS plastic or prepared from a waste PS plastic and a modification material, where a content of the waste PS plastic is greater than or equal to 1% and less than 100% and a content of the modification material is greater than 0% and less than or equal to 99%. The preparation of the recycled PS plastic film with the waste PS plastic can save resources. In addition, the waste PS plastic is modified by the modification material to improve the performance of the plastic, which is conducive to preparation of an acousto-magnetic (AM) anti-theft label housing with excellent performance. Also disclosed are a preparation method of the recycled PS plastic film, an AM anti-theft label housing made of the recycled PS plastic film and a preparation method thereof, and a corresponding AM anti-theft label.

Abstract: A method for stabilizing rice bran with complex enzyme involving enzymatic hydrolysis combined with thermal processing to stabilize rice bran, includes compounding at least one of glycosyl hydrolases such as cellulase, hemicellulase and alpha amylase into a complex enzyme solution, and performing enzymatic hydrolysis on the rice bran with the complex enzyme solution, and after enzymatic hydrolysis, performing thermal processing and inactivating enzyme treatment on rice bran using the moist-heat method, microwave method and/or extrusion expansion method, to prepare the stabilized rice bran. From the perspective of reducing bound lipase from rice bran, the glycosyl hydrolase is used to catalyze conversion of bound lipase in rice bran into free lipase, thereby effectively improving inactivation efficiency of rice bran lipase. The rice bran prepared using the method has characteristics of low residual activity of lipase and long shelf life, and may be directly applied to industries such as food and cosmetics.

Abstract: A penetrating canaloplasty for treating angle-closure glaucoma that retains the advantages of canaloplasty, namely, internal drainage and non-bleb-dependence; the sclera is tightly sutured so as to avoid ocular hypotension and shallow anterior chamber complications; bleb-related complications such as postoperative infection and dry eye are avoided; since an inner wall of the Schlemm's canal is resected, it is possible to improve long-term success rates; indications are widened, including angle-closure glaucoma and all of glaucoma patients applicable to trabeculectomy. Traditional trabeculectomy forms blebs through outer filtering to reduce intraocular pressure, and the existence of blebs can influence postoperative living quality of patients.
