The invention relates to the field of biomedicine and particularly relates to oligonucleotide for promoting repair of skeletal muscle injury and an application method thereof. The invention firstly discloses oligonucleotide which is screened from transcripts of human-derived growth imprinted gene H19 and has a function of obviously promoting myogenic differentiation of skeletal-muscle myoblast. The oligonucleotide is characterized by being shown in sequences of SEQ ID NO:1 and SEQ ID NO:2. The oligonucleotide and the application method have the advantages of simple operation, no risk, promotion for fast regeneration of new muscle fiber after skeletal muscle injury and good function restoration. Therefore, the oligonucleotide and the application method have good application prospect in genetherapy of skeletal muscle injury caused by acute contusion, crush injury, explosion injury or chemical substances.

The invention relates to the technical field of medical instruments and discloses a first-aid instrument for crush injury. The first-aid instrument comprises a microcontroller, a hemostasis air belt, a blood flow detecting device, a pressure device and a decompressing device. The blood flow detecting device is connected with the microcontroller and used for detecting blood flowing information in crush-injured limbs, transmitting blood blocking signals to the microcontroller when blood is blocked and transmitting blood flowing signals to the microcontroller when the blood flows. The pressure device is connected with the hemostasis air belt and the microcontroller and used for inflating the hemostasis air belt under the control the microcontroller to block blood flowing. The decompressing device is connected with the hemostasis air belt and the microcontroller and used for deflating the hemostasis air belt under the control of the microcontroller to recover blood flowing. The microcontroller is used for controlling the pressure device to inflate the hemostasis air belt and controlling the decompressing device to deflate the hemostasis air belt in circulation mode. By using a medical means of ischemic postconditioning, ischemia reperfusion damage on the crush-injured limbs after stress is removed is relieved, and a purpose of protecting the injured limbs is achieved.

The invention discloses a door structure of swinery feeding equipment. The door structure comprises an entering channel and an exiting channel; a feeding trough is arranged between the entering channel and the exiting channel; left and right door hinges are respectively arranged at left and right sides of the inlet of the entering channel, and a return spring and a door lock mechanism are installed between two doors; a barrier door and a folding door mechanism are sequentially arranged behind the left and right door hinges; the folding door mechanism is composed of a primary folding door and a secondary folding door with the front end which is hinged with the middle part of the primary folding door; tensioning springs which are at an anticlockwise expansion tendency all the time are arranged at the tail end of the secondary folding door and the end part of the primary folding door; the barrier door and the primary folding door can be rotated along installation rotary shafts of respective end parts and are provided with corresponding return springs which enable door faces to be naturally vertical to the side edges of the channels. According to the door structure provided by the invention, a plug is arranged for self-protection and companions are moderately expelled by using the forward-movement power to eat through the interaction of the left and right doors, the barrier door and the folding door mechanism, so that the direct attack is avoided and the serious incidents such as crushing injury, abortion and the like which are caused by acute behaviors of pigs are avoided.

The invention provides a stretcher constraining quilt, comprising two strip-type constraining quit bodies, one end of each constraining quilt body is connected with the side face of a stretcher bed by a zipper, the other end of each constraining quilt body can be mutually zipped up together to form constraint to a patient, multiple zipper tooth structures are arranged at a top edge of the outside surface of each constraining quilt body along the vertical direction, and the degree of tightness of the constraining quilt is adjusted conveniently. The stretcher constraining quilt can be filled with cotton fibre or is provided with air holes so as to meet the demand of use in winter and summer, and the humanistic care can be embodied, by using the constraining quilt, when an irritable and unconscious patient is transferred, the occurrence of the situations such as falling out of bed, crush injury, scratch, skin breakage caused by rub, disturbance of blood circulation and the like can be avoided, and discomfort of the patient and the burden of a stretcher bearer can be relieved.

The invention relates to a computer desk device, in particular to a wall-mounted multifunctional computer desk device. The wall-mounted multifunctional computer desk device includes a movable massagepedal mechanism, an integral hydraulic lifting mechanism and a heat dissipation computer desk mechanism. The device can adjust the width and height of a computer desk, adjust the height integrally, cool a computer and slightly adjust the angle of the desktop. The device can be adjusted according to preferences of different people, the device can massage the feet, protect the legs of people and prevent crush injury, the movable massage pedal mechanism is located on the lower portion of the heat dissipation computer desk mechanism through welding, the heat dissipation computer desk mechanism isconnected with the integral hydraulic lifting mechanism, and the heat dissipation computer desk mechanism is connected with the integral hydraulic lifting mechanism through partial welding and partialclearance coordination.

The invention relates to the technical field of clinic, and specifically relates to a separation method for rabbit optic nerves and a method for manufacturing a rabbit optic nerve crushing injury model. The method is simple in steps, easy in operation, small in operation wound, low in infection probability, short in operation time and anesthesia time, high in consistency, and consistent in injurydegree, and can provide basis for a rabbit optic nerve crushing injury model, a rabbit optic nerve quantitative impact damage model, and a rabbit optic nerve chemical agent firing damage model.
