Abstract: Implantable materials may be used as spacers for separating tissues to reduce a dose of radioactivity received by one of the tissues. Applications include introducing a hydrogel spacer to a position between a first tissue location and a second tissue location to increase a distance between the first tissue location and the second tissue location, Further, there may be a step of administering a dose of radioactivity to at least the first tissue location or the second tissue location and/or a step of visualizing margins of the hydrogel spacer. A hydrogel spacer may comprise a polysaccharide and a radioopaque agent and may be used for fiducial marking.
Abstract: A high-efficiency anti-tumor nano-drug delivery system containing hydralazine (hydralazine-nanoparticles abbreviated as H-NPs) is provided. The drug delivery system takes hydralazine and doxorubicin combined by a ?-? bond as a hydrophobic core and takes dextran as a hydrophilic shell. The high-effective anti-tumor nano-drug delivery system containing hydralazine can increase the vascular permeability and blood perfusion of the tumor site, improve the enrichment and penetration of nanoparticles in the tumor, reduce tumor hypoxia, increase the sensitivity of the tumor to a chemotherapy drug doxorubicin, and significantly improve its anti-tumor effect by expanding the tumor blood vessels and regulating tumor microenvironment (TME).

Abstract: This invention provides methods for producing a polymer particle which contains unusually high negative charges on the surface of the particle. Preferably, the polymer is pharmaceutically acceptable. The negative charges can be conferred by chemical groups such as carboxyl, sulfonate, nitrate, fluorate, chloride, iodide, persulfate, and many others, with carboxyl group being preferred. The invention also provides polymer particle produced by the methods of the invention.
Abstract: The disclosure provides, among other things, compositions that bind to and inhibit the biological activity of soluble biomolecules, as well as pharmaceutical compositions thereof. Also provided herein are a number of applications (e.g., therapeutic applications) in which the compositions are useful.
Abstract: An injectable in situ pore-forming hydrogel system and its preparation method and use are provided. The injectable in situ pore-forming hydrogel system uses an injectable hydrogel as a continuous base phase, and isolated live cells and magnesium particles are distributed in the continuous base phase, where the injectable hydrogel is a precursor or prepolymer of hydrogel, which can form hydrogel by cross-linking. The injectable in situ pore-forming hydrogel system can be used to create pores while the gel encapsulates live cells, which makes use of both the injectability and porous structures of hydrogel, which is important for the repair of cavitary, surgically difficult and irregularly defective tissues; meanwhile, magnesium particles generate magnesium ions after the former undergoes gas production and degradation, which can improve the bioactivity of the gel and aid in tissue repair.
