The invention provides an ultrasonic fat-reducing device, which comprises a main unit and a treatment mechanism connected with the main unit, the treatment mechanism comprises ultrasonic transducers (1) and a clamping unit for clamping skin, and the ultrasonic waves emitted by the ultrasonic transducers can act on the skin clamped by the clamping unit. By utilizing ultrasonic energy to destroy fat tissue layers, the ultrasonic fat-reducing device can achieve the purpose of reducing fat, meanwhile, the treatment process is safe and effective, the tissue layers of the human body cannot be injured, and therefore the ultrasonic fat-reducing device is a safe and effective external noninvasive ultrasonic fat-reducing device.

The invention discloses equipment for treating vitligo by utilizing turnable lattice dual wavelength laser. A superpulse CO2 laser device and an ultraviolet laser device are integrated in the equipment. Under the control of a control system, the superpulse CO2 laser and the ultraviolet laser can be outputted according to pulse width, peak value power and pulse power, which are required by therapy, are respectively outputted through a beam switcher according to requirements, and are outputted to a two-dimensional optical scanning polariscope system through a coupler and a guiding arm. Then, the laser beams are outputted by the optical scanning system in a lattice distribution form, and are irradiated on focuses of skin surfaces of patients after being focused by a focusing mirror, thus, the equipment for treating vitligo by utilizing turnable lattice dual wavelength laser is manufactured. The device is mainly used for treating vitligo, particularly is suitable for treating acral vitligo, and is also suitable for treating neurodermatitis (hypertrophic type), chronic eczema, psoriasis, trichophytia, alopecia areata, scleriasis, lymphoma cutis and the like.

The invention discloses a polyvinyl alcohol nanofiber emboliaztion agent as well as a preparation method and application thereof and belongs to the field of vascular thrombosis materials for interventional therapy. The polyvinyl alcohol nanofiber emboliaztion agent consists of polyvinyl alcohol electrostatic spinning nanofiber granules, wherein the particle sizes of the nanofiber granules is 100-300mu m. The preparation method comprises the following steps: dissolving polyvinyl alcohol granules into water, and heating till the polyvinyl alcohol granules are completely dissolved so as to obtaina polyvinyl alcohol solution of an appropriate concentration as an electrostatic spinning solution; preparing a polyvinyl alcohol nanofiber film from the electrostatic spinning solution by using electrostatic spinning equipment; performing thermal treatment on the nanofiber film; shearing the nanofiber film after thermal treatment, performing low-temperature crushing treatment, and screening, thereby obtaining the polyvinyl alcohol nanofiber granules of which the particle size is 100-300mu m. The emboliaztion agent disclosed by the invention has relatively good treatment effects and biological security, and can be also applied to arterial embolism of various types of malignant tumor such as primary liver cancer and kidney cancer.

The invention discloses a framework for encoding double-specificity molecules of mediated secretion effector cells and killing target cells as well as a virus. Recombinant protein provided by the invention comprises a functional area I and a functional area II, wherein the functional area I is specifically combined with tumor-associated antigens or HLA (human leukocyte antigen) polypeptide compounds on tumor cells; and the functional area II is specifically combined with surface markers of T cells or surface markers of NK cells. According to the invention, after the provided recombinant adenovirus infects the tumor cells, the tumor cells become places for double-specificity recombinant protein expression; compared with direct supply of fusion protein, treatment times can be reduced, the adenovirus is guided into a tumor in an orthotopic injection mode, and the expressed fusion protein can be combined with the tumor cells immediately without in-vivo metabolism; and compared with direct injection of the fusion protein, the efficiency is higher, and the tumor cells can be killed once the effector cells appear around the tumor. The framework and the virus have great significance for oncotherapy.

The invention discloses a needle structure for acupuncture treatment. The structure comprises a needle body and a needle handle, and a needle tip structure is formed at the front end of the needle body; the needle handle is of a tubular structure with an opened end face and a closed other end face; and the needle body is inserted into the inside of the needle handle from the opened end face of theneedle handle and is connected with the needle handle in interference fit; the outer diameter of the needle body is 0.49-0.53mm; and the length of the tip is 0.8-2.2mm. The needle structure for acupuncture treatment, which is disclosed by the invention, is simple and reasonable in structure, has the characteristic of a large diameter when being compared with a conventional acupuncture needle, andis capable of reducing the needle threading times when being compared with a conventional needle cutter. The purpose that one needle has multiple directions, multiple angles and wide acupuncture ranges can be achieved. The acupuncture times can be reduced in treatment on muscle bundles and fascia, myofibril filaments can be thinned and softened, two needles are used at most, acupuncture pain canbe avoided, the treatment times can be reduced, and a good clinical effect can be achieved.

The invention discloses a new function of cediranib (CED), namely application of the cediranib (CED) in the technical field of tumor cell radiosensitization drugs in cooperation with X-ray radiation. A radiation sensitizer containing the cediranib has the effects of inhibiting tumor cell proliferation and inducing tumor cell apoptosis in cooperation with X-ray radiation. Therefore, the required radiation dose for X-ray irradiation on tumor cells can be reduced, and apoptosis of more tumor cells can be promoted. Therefore, the invention provides a potential application value of cediranib in preparation of radiotherapy sensitization drugs.
