The invention discloses a method for preparing titanium metal with the antimicrobial and anticancer performance. The method includes the following steps that 1, a ruthenium complex is prepared; 2, by weight, 0.1-0.6 part of cyclodextrin is dissolved in 3.5-20 parts of water and evenly stirred, and then 0.5-1.5 parts of titanium metal is added and soaked for 20-60 min; 3, by weight, 0.2-1.2 parts of the ruthenium complex is added, and then the mixture is treated for 30-60 min with 15-30 kHz ultrasonic waves; 4, the titanium metal is taken out and dried. According to the method, due to the effects of the cyclodextrin and the ruthenium complex on the titanium metal, the titanium metal has the good antimicrobial and anticancer performance, the surface of the titanium metal is beneficial to growth of osteocytes, the incidence rate of complications caused by the titanium metal in an osseointegration operation is reduced, and a safer and more reliable material is provided for the osseointegration operation.

The invention discloses a method for preparing stainless steel with antibacterial and anti-cancer properties by means of a rhodium complex. The method comprises the following steps that 1, the rhodium complex is prepared; 2, 0.1-0.6 part by weight of cyclodextrin is dissolved in 3.5-20 parts by weight of water, even stirring is conducted, 0.5-1.5 parts by weight of stainless steel is added, and soaking is conducted for 20-60 min; 3, 0.2-1.2 parts by weight of rhodium complex is added, ultrasonication is conducted for 30-60 min at 15-30 kHz; 4, the stainless steel is taken out and dried. According to the method for preparing the stainless steel with the antibacterial and anti-cancer properties by means of the rhodium complex, by means of the action of the cyclodextrin and the rhodium complex on the stainless steel, the stainless steel has good antibacterial and anti-cancer properties, the surface of the stainless steel facilitates growth of bone cells, the morbidity of complications caused by the stainless steel in an osseointegration operation is decreased, and a safer and more reliable material is provided for the osseointegration operation.

The invention discloses an iridium complex with an anti-tumor effect through synergism of chemotherapy and phototherapy and a preparation method and application of the iridium complex. The iridium complex is characterized in that the chemical structural formula of the iridium complex is shown in the description. The iridium complex can be used for preparing medicines for treating cancers and hypertension, has the effects of chemotherapy and phototherapy, has good biological activity, has a conjugated system structure and is more stable in molecule. The preparation method is simple and low in cost.

The present invention provides an electron injection material, as shown in formula (I); wherein, the R 1 with R 2 Each independently is a substituted or unsubstituted alkylamino group, a substituted or unsubstituted heterocyclic group, and a derivative group thereof. Compared with the prior art, the adamantane organic base provided by the present invention takes amantadine as the core, and at the same time connects a structure capable of transporting electrons as an electron injection material, which can form a hydrogen bond with the electron transport material to achieve high electron density. Injection ability, it does not need to consider ionization energy, and the synthesis of the electron injection material is simple, the molecule is stable, while ensuring the formation of hydrogen bonds, the molecule also has flexible branched chains, which is convenient to make inkjet materials, not only can be used for direct vapor deposition Coating can also be used to make devices in the form of inkjet, which helps to reduce costs.

The invention discloses a Trichinella Spiralis larva ES antigen gene vaccine and a preparation method thereof. Trichinella Spiralis larva 43ku and 45ku ES protein genes are respectively inserted to a pVAXI eukaryotic expression vector to obtain recombinant plasmids, and the recombinant plasmids are mixed according to a ratio of 1:1 to prepare a combined recombined DNA vaccine for preventing Trichinella Spiralis infection and improving the worm reduction rate of bodies. After the injection immunization of hindlimb muscles of mice for three weeks, 2000 worms are killed, the worm reduction rate can reach 76.65%, and the quantity of eggs at the tongue tissues of the mice is obviously reduced.
