摘要:A nucleic acid synthesis device and a nucleic acid purification device, uses thereof, and a nucleic acid synthesis method and a nucleic acid purification method. The nucleic acid synthesis device includes a solid support, and the solid support includes a controlled pore glass (CPG), the CPG is an unmodified and bare CPG, a surface of the CPG has a hydroxyl group, and the hydroxyl group is attachable, though a covalent bond, to a phosphoramidite-protected nucleotide monomer or multimer for synthesis of nucleic acid. The nucleic acid synthesis device of the present disclosure can be used for not only synthesis of an oligonucleotide primer, but also for purification of enzymatic digestion and PCR product by using the oligonucleotide primer immobilized on the CPG, and has advantages of simple structure, small volume, light weight, high efficiency, low costs, and diversified functions.

摘要:Gd-encapsulated carbonaceous dots (Gd@C-dots) hold great potential in clinical translation as Ti contrast agent for magnetic resonance imaging. However, current synthetic techniques yield particles with poor size control; hence, time-consuming size selection is often needed to obtain particles of desired sizes. Disclosed is a process whereby mesoporous silica nanoparticles are used as templates for size-controlled synthesis of Gd@C-dots. The disclosed methods involve calcining a mixture comprising a mesoporous silica nanoparticle, a gadolinium-containing compound, and a chelator, thereby forming the nanoparticles of gadolinium within the mesoporous silica nanoparticle; and removing the mesoporous silica nanoparticle from the nanoparticles of gadolinium.

摘要:Disclosed is a total flavonoids extract of Gynura formosana Kitam., containing 80%-85% of rutin by weight percent content. The results of pharmacological experiments show that the extract can lower the activity of xanthine oxidase in the liver of a hyperuricemia model mouse and reduce the synthesis of uric acid to a certain degree and has a certain uric acid-lowering effect, and can be used as a potential drug for treating hyperuricemia or gout. The method for preparing the total flavonoids extract of Gynura formosana Kitam. comprises: after an extraction step, selecting a complex enzyme composed of enzymes with a specific composition and a specific ratio for enzymolosis, and further carrying out the step of extracting and concentrating with macroporous resin and isolating and purifying with macroporous resin, so that the HPLC purity of rutin in the resulting total flavonoids extract of Gynura formosana Kitam. reaches 80%-85%.
