Abstract: The present disclosure provides use of a transmembrane emp24 domain 8 (TMED8) gene in preparation of a drug and a diagnostic kit for pancreatic cancer, and belongs to the technical field of precision tumor medicine. In the present disclosure, it is found that up-regulating an expression level of the TMED8 gene has significantly inhibited migration and proliferation of pancreatic cancer cells, and then promoted apoptosis of the pancreatic cancer cells; the TMED8 gene is further found to be related to a mitogen-activated protein kinase (MAPK) signaling pathway. Therefore, the TMED8 gene may be used as an effective target for gene diagnosis and treatment of the pancreatic cancer.

Abstract: A notebook computer is disclosed in the present invention which comprises: a screen, which is a touch screen configured to be operable via touching; a host, which is integrated in the screen; and a keyboard, which is detachably connected with the screen so that the keyboard and the screen can be in a state of being connected to each other or in a state of being separated from each other in use. When the notebook computer is used, the keyboard and the screen can be in the state of being separated from each other in use, so that the screen and the keyboard of the notebook computer are used separately. And the keyboard and the screen can be separated when needed and the notebook computer can be use by touching operation on the screen.

Abstract: The preparation of Pleurotus tuber-regium polysaccharide functionalized nano-selenium hydrosol with anti-tumor activity includes the following steps: 1) at normal temperature and under normal pressure, adding a Vitamin C solution to an aqueous solution of Pleurotus tuber-regium polysaccharides, and mixing uniformly; 2) adding dropwise a selenium dioxide solution or a selenite solution to the solution while mixing uniformly; and 3) adding water to the solution to a pre-determined volume, to obtain a Pleurotus tuber-regium polysaccharide functionalized nano-selenium hydrosol when the red color of the product is no longer deepened. The polysaccharides are used to control the particle size of nano-selenium, to obtain functionalized nano-elemental selenium with high anti-tumor activity and low toxicity. The anti-tumor activity of the biologically active molecule polysaccharides and the physiological effect of nano-selenium are combined, and a synergistic anti-tumor effect is achieved.
