Abstract: The present invention discloses a semi-radial head prosthesis for matching to a non-fractured part of a bone. The prosthesis comprises a prosthesis head (3) matching to a radial head of the non-fractured part, the prosthesis head having a fractured surface, the prosthesis head (3) is jointed with the non-fractured part (2) to form an intact radial head. In the present invention, when the partial articular surface of the radial head is fractured, it is unnecessary to remove the entire radial head. Instead, the radial head of the fractured part is replaced with a prosthesis head and the radial head of the non-fractured part is retained. The two parties are combined to form an intact radial head. This minimizes iatrogenic injuries to the patients, and is good for the joint intactness and joint stability.

Abstract: The present invention relates to the technical field of medicine, which provides a liposomal docetaxel palmitate formulation and a method for preparing the said formulation. The liposomal docetaxel palmitate formulation contains docetaxel palmitate as the main drug, a chelating agent, lecithin and DSPE-PEG2000. It is characterized in that docetaxel is prepared into a docetaxel palmitate lipophilic prodrug, thus overcoming the defect that docetaxel cannot be processed into liposomes due to poor hydrophilicity and hydrophobicity. The liposome prescription of this invention contains a chelating agent with a substantive effect that can prolong the action time of the drug in the body, improve the anti-tumor effect and be prepared smoothly. Therefore, the chelating agent in the formulation is the core technical feature of the present invention.
