The invention belongs to the technical field of marine organisms, and concretely relates to a method for the efficient ultralow temperature cryopreservation of turbot sperms. The method comprises the following steps: mixing the seminal fluid of turbots with an antifreeze liquid according to a volume ratio of 3:1-4:1, carrying out two-step cooling treatment, carrying out one-step balancing, adding to liquid nitrogen (having a temperature of -196DEG C), and preserving; and the antifreeze liquid is composed of a diluent, an antifreeze agent and an additive. High-quality frozen sperms obtained through the method for the efficient ultralow temperature cryopreservation of turbot sperms are of great significance of the artificial breeding, germplasm preservation, heredity diversity and sustainable culturing of the turbots.

The invention relates to a freezing gun for puncture type cryotherapy. The freezing gun comprises a shell, a hydraulic transmission mechanism, a liquid storage container, a button and a plurality of freezing heads. One end of the hydraulic transmission mechanism is connected with the button, and the other end of the hydraulic transmission mechanism is connected with the liquid storage container; by pressing the button, the thrust of a syringe needle on the liquid storage container is effectively increased, and stable puncture is achieved. The freezing heads are installed at the front end of the liquid storage container and used for installing the syringe needle, and a liquid conduction device is arranged at the end, provided with the syringe needle, of the corresponding freezing head. After the syringe needle is installed, the interior of the corresponding freezing head is in a conduction state, and low-temperature liquid in the liquid storage container flows into the syringe needle through the corresponding freezing head. When the syringe needle is not mounted, the interiors of the freezing heads are in a closed state. The freezing gun is suitable for cryotherapy or injection of large-area irregular-shaped lesion areas, and the number and position of freezing needles can be adjusted according to the shapes and sizes of the areas, so that cryotherapy is more precise and more efficient, and meanwhile the doctor-patient experience is effectively improved.

The invention discloses an infrared physiotherapy instrument for cervical vertebrae and lumbar vertebrae. The infrared physiotherapy instrument for the cervical vertebrae and the lumbar vertebrae comprises an outer wrapping bag (1), wherein tightening devices are respectively arranged on two sides of the outer wrapping bag (1), and a heating element which is arranged in the outer wrapping bag (1) is a low-temperature radiating electric heating film (3). According to the infrared physiotherapy instrument for the cervical vertebrae and the lumbar vertebra, infrared rays are utilized as a source of radiation, and therefore not only can the infrared rays be absorbed rapidly, but also the infrared physiotherapy instrument is simple in structure and convenient to carry.

The invention provides a composition for eyes and having improved drying protection and retention, and belongs to the field of pharmaceutical preparations. The composition includes cyclosporin, nano micelle in-situ gel, and hyaluronic acid or a pharmaceutically acceptable salt thereof; and the composition is in a liquid form at normal temperature or low temperature, is a hydrosol form when the temperature is more than 35 DEG C, and can still maintain complete under the shear stress caused by the eyelid blinking of patients. A preparation method includes providing first solute and second solute; and mixing the solute under a condition of taking water as a substrate so that the composition including gel dispersoid can be formed. The provided composition is high in bioavailability and small in effect on eye pain and irritation, cannot cause the blurring of vision, can improve the compliance of the patients and/or reduce side-effects, can enhance ocular surface health, and has antibacterial and antiseptic effects; and the preparation method can increase adhesiveness, enhance gelation temperature, prolong retention and effective acting time, rising encapsulation yield, avoid self-agglomeration phenomenon, and enhance antioxidant protection effects and stability performance.

A medical-liquid heating disinfection cabinet for operating rooms comprises an ozone generator, a heater, a refrigerator, a first single-chip microcomputer, a second single-chip microcomputer, a disinfection-time control screen (3) and a temperature control screen (4); the disinfection-time control screen is connected with the ozone generator via the first single-chip microcomputer; the temperature control screen is connected with the heater and the refrigerator via the second single-chip microcomputer; the heating disinfection cabinet is inside provided with an upper heating disinfection area (1) and a lower heating disinfection area (2); the upper heating disinfection area is used to store medical rigidly-packaged liquids, and the lower heating disinfection area is used to hang flexibly-packaged liquids; the temperature control screen is capable of heating or cooling a medical liquid; and the disinfection-time control screen is capable of disinfecting the disinfection cabinet. The medical-liquid heating disinfection cabinet is well applicable to standard operating rooms, is capable of effectively reducing hypothermia generation risk in an operation or after an operation, and thereby reaching infection control requirements and satisfying multiple requirements of operating rooms.
