The invention discloses a culture solution for improving the development rate of in-vitro cultured pig blastocysts as well as application and a use method of the culture solution, and belongs to the technical field of livestock embryo engineering. The invention discloses a culture solution for improving the development rate of in-vitro cultured pig blastocysts, which is characterized in that a PZM3 culture solution is used as a basic culture solution, and 5-25ng / mL of tumor necrosis factor superfamily cell factor TNFSF12 is added. According to the present invention, the pig embryo needs to be subjected to in-vitro culture for 4 days in the TNFSF12-free basic culture solution, and then is transferred to the TNFSF12-containing basic culture solution so as to be continuously cultured for 2 days, such that the generation efficiency of the pig blastocyst can be effectively improved, and the support is provided for the application of the pig in-vitro fertilization, the somatic cell nuclear transfer, the embryo genome selection and other embryo engineering technologies in the agricultural breeding and the human medicine;

The present application provides a kind of detection method of bacterial endotoxin in PHA gel filling agent.The filling agent of the present application comprises PHA microspheres, gel carrier sodium carboxymethyl cellulose, osmotic pressure regulator, pH regulator and water for injection, the present application systematically studies the influence of gel carrier and osmotic pressure regulator on the performance of composition shear viscosity and osmotic pressure, and scientifically selects the excellent and stable gel prescription.The present application accidentally finds that the combination of water and a small amount of dichloromethane can realize the sufficient release of endotoxin, and accurately detect its content.The method of the present application can effectively ensure the safety of human medicine, and has important industrial value.

A tool kit for minimally invasive implantation of a tendon fixation implant in the field of arthroscopic human medicine is provided. The tendon fixation implant includes a medial anchor, a lateral anchor, and a base plate. The tool kit includes a medial anchor inserter having a medial anchor drive mandrel and a medial anchor release tube. The medial anchor release tube is designed to receive the medial anchor drive mandrel. The medial anchor drive mandrel is designed both to receive a medial anchor and to introduce the medial anchor into bone by driving it into the latter. The medial anchor drive mandrel has a locking head for locking the medial anchor drive mandrel to the medial anchor release tube. The tool kit includes a base-plate inserter having a handpiece and a base-plate inserter tube designed to receive the base plate of the tendon fixation plate.
