Provided is a cable connecting device including a conductive casing. The conductive casing encloses a first core wire fixing member and a second core wire fixing member for fixing a first data cable and a second data cable, and a connecting device electrically connecting the core wire of the first data cable to that of the second data cable, moreover, the conductive casing is electrically connected with shielding members of the two cables. The connecting device includes a plurality of conductive connecting elements which are provided with first contact areas and second contact areas communicated with the core wire contacts of the first cable and the second cable. The core wire fixing members are provided with a plurality of placing areas on which core wire end areas can be arranged. The core wire fixing member is inserted into the casing, and the first contact areas of the connecting elements are respectively jointed into the placing areas of the first core wire fixing member, and the second contact areas are respectively jointed into the placing areas of the second core wire fixing member. The core wire fixing members are respectively maintained on cable fixing members, the cable end areas can be fixed on the cable fixing members, and shielding contact elements are maintained on the cable fixing members to establish the conductive connection between the shielding members of the cables and the casing.

The invention relates to a connector for medical liquid-containing packages, in particular to infusion or transfusion bags comprising a connection element (1) provided with a channel-shaped opening (1c) in which a self-sealing membrane (8) is arranged. A breakable part (17) which is connected to the connection piece closes the channel-shaped opening. Above the membrane (8), said connection element is embodied in the form a connection piece (13) comprising an internal cone (14) and external thread (15), the membrane (8) being sealed for receiving a syringe cone shaft. The inventive connector makes it possible to inject an active substance by means of a conventional Luer lock syringe devoid of an injection cannula (needle).

The invention discloses a preparation method and application of antrodia antrodia mycelium medium, which is a liquid culture obtained by mixing Juncao Ganoderma lucidum extract, glucose, maltose, yeast extract, KH2PO4, MgSO4·7H2O and VB1 according to a certain ratio base. The invention has the characteristics of rapid germination, large amount and rapid growth of the mycelium of Antrodia camphorata, and the polysaccharide content of the mycelia can reach 0.43-0.97%, and the content of triterpenes is 0.2%-0.41%, which are respectively 2 times higher than the traditional culture medium. The method can provide a large amount of mycelium of Antrodia camphorata in actual production, and the preparation method is simple, highly repeatable, and easy to operate.

Disclosed are a method for manufacturing a cell sheet, comprising culturing cells on a fibrin-coated surface of a substrate until the cells reach confluency, continuing the cultivation of the cells for a sufficient time period to cause the degradation of fibrin at the bottom of the cells, and detaching the cultured cells from the substrate surface in a sheet-like form to give a cell sheet; a substrate for cell sheet preparation, a surface of which is coated with fibrin; and a composition for use in coating with fibrin a surface of a substrate for cell sheet preparation, the composition comprising fibrinogen and thrombin. The invention enables to cell sheets to be manufactured by a simple manipulation using a substrate coated with a commercial, commonly available material of which safety has been confirmed.
