The invention belongs to the technical field of medical instruments, and relates to a disposable soft connecting band collection container and an anti-freezing vacuum blood taking needle of a bleeding opening. The disposable soft connecting band collection container is formed in the following mode that: a biological product anticoagulant coating layer is arranged on an inner cavity wall of a circular connector; one end of the connector is provided with a blood taking plastic duct; a vacuum valve is placed on the plastic duct; the other end of the plastic duct is provided with the circular connector; the inner cavity wall of the circular connector is provided with the biological product anticoagulant coating layer; one end of the connector is provided with a venous blood taking needle, while the other end is provided with a blood collection sample bottle needle; the blood collection sample bottle needle is connected with a blood collection sample bottle cap; the blood collection samplebottle cap is connected with a rubber plug; the rubber plug is connected with a blood collection sample bottle; and one side on the blood collection sample bottle close to the blood collection samplebottle cap is provided with a secondary bleeding opening. The disposable soft connecting band collection container and the anti-freezing vacuum blood taking needle of the bleeding opening can ensure that a blood sample generates no cruor and hemolysis so as to ensure the accuracy of the test result. The blood dosage during the test can be controlled flexibly so as to ensure repeated tests at any time or the addition of new testing items.

The invention provides a fan. The problem that the assembly of a fan in the prior art is time-wasting and inconvenient is solved. The fan includes a motor, two frames, an impeller and a housing assembly. The two frames are coupled with an outer periphery of the motor and are engaged with each other by way of fastening. Each of the two frames includes one groove. The impeller is connected to the motor and is driven to rotate by the motor. The housing assembly houses the impeller and includes first and second housing parts. The first and second housing parts are engaged with each other by way of fastening. A protruding lip is provided on one of two end faces of the first housing part which is relatively adjacent to the motor. Another protruding lip is provided on one of two end faces of the second housing part which is relatively adjacent to the motor. The protruding lip and the other protruding lip are engaged with the grooves of the two frames.

The invention belongs to the technical field of insect rearing, and specifically discloses a method for raising a large number of indoor test populations of the weaver moth. According to the mating and oviposition characteristics of the cocoa moth, the present invention improves the existing breeding method of the cocoa moth. The egg site increases the spawning area and improves the survival rate of eggs; finally, it simplifies the cumbersome procedures of egg collection in separate test tubes and larvae feeding and replacement of leaves, greatly reducing the workload, and can truly achieve high survival rate, simplified procedures, and large-scale standardization. The experimental population of the cocoa weaver moth.

The invention discloses genetically engineered bacteria and application thereof to preparation of rebaudioside A. The genetically engineered bacteria capable of producing stevia rebaudiana glycosyl transferase UGT76G1 and UDP-glucose pyrophosphorylase UGPase are obtained through construction, and perform overexpression on the UDP-glucose pyrophosphorylase UGPase on the basis of performing constitutive expression on recombinant bacteria of the stevia rebaudiana glycosyl transferase UGT to increase the glycosyl donor quantity of glycosylation reaction. A whole-cell catalytic reaction system is established, and stevioside is converted into the rebaudioside A. The dosage concentration of the bacteria is 1 to 10 g / L, the dosage of glucose is 20 to 120 g / L and the dosage of the substrate stevioside is 1 to 20 g / L. In the catalytic reaction process, a cell catalyst is subjected to surfactant treatment, the cell permeability is improved and the yield of the rebaudioside A is greatly increased. A synthetic route of intracellular UDPG is utilized, so the glycosyl donor quantity of the intracellular UDPG is increased, additional addition is avoided and regeneration cycle is realized; and cultivation of yeast and expression of recombinase are conducted simultaneously, so the cycle of the cultivation of the recombinant bacterial and the expression of the recombinase is shortened.

The invention provides a method for making an anti-epidemic spectacle frame and the anti-epidemic spectacle frame. The method comprises: adding nylon TR80 and an anti-epidemic agent into a ball mill, wherein the composition of the anti-epidemic agent includes zirconia (ZrO 2 ), barium titanate (BaTiO 3 ), molecular sieve catalyst and europium trioxide (Eu 2 o 3 ), the raw materials are subjected to steps such as ball milling and stirring to obtain a mixture; the mixture is input into a granulator for granulation, and the granulated mixture is injected into a mold for molding to obtain a molding raw material; the molding raw material is placed in an environmentally friendly solvent for soaking Finally, drying; degreasing the dried molding raw materials, and sintering the degreased molding raw materials to obtain blanks; polishing and glazing the blanks to obtain anti-epidemic spectacle frames. In the present invention, the anti-epidemic agent is added into the raw material of the spectacle frame, so that the spectacle frame obtained has an anti-epidemic effect, and the damage to human skin caused by spraying the bactericide or the bactericidal liquid is prevented.
