Abstract: The invention discloses a natural gas diffusion coefficient measurement auxiliary device based on a hand-operated lifting device, comprising a core chamber, a bracket, a core preservation device, and a hand-operated lifting device; the left side of the core chamber is connected with a methane measuring chamber, and the right side of the core chamber is connected with a nitrogen measuring chamber; a rotatable bracket is installed on the lower left side of the core chamber, and the lower right side of the core chamber is connected with the hand-operated lifting device; the core chamber is rotated by the hand-operated lifting device with the support as the center; a horizontal platform at the lower part of the core chamber is provided with a revolving door that can accommodate the left end of the core chamber; a core preservation device is installed at the lower part of the revolving door.

Abstract: A hypothermic oxygenated perfusion solution for repairing kidney injury and use thereof belongs to the technical field of medical treatment. The hypothermic oxygenated perfusion solution is an organ preservation solution carrying carbon monoxide-releasing molecules. The hypothermic oxygenated perfusion solution can significantly increase the perfusion flow of the kidney, reduce the intrarenal resistance and significantly improve the histopathological integrality. The hypothermic oxygenated perfusion solution is provided for specifically repairing the kidney from donation after circulatory death donors, and has a huge application prospect for clinical transformation.

Abstract: Provided are a small molecule compound combination for reprogramming digestive tract derived epithelial cells to endodermal stem/progenitor cells, a reprogramming method and an application. Human gastric epithelial cells (hGECs) are used as initiating cells, human gastric subepithelial myofibroblasts (aGSEMFs) are used as a trophoblast, a compound combination having all or a plurality of FBP, Bay K 8644, Bix01294, SB431542 or A813-01, VPA, RG108, PD0325901 and PS48 including SB or A83 is used to reprogram digestive tract derived epithelial cells to endodermal stem/progenitor cells, and the endodermal stem/progenitor cells can be used for inducing differentiation towards liver cells, pancreatic beta cells and intestinal cells.
