The invention discloses an injection-type bone morphogenetic protein with fibrin as a carrier, which is suitable for the treatment of clinical fractures, nonunions and bone defects. It is based on the fibrin isolated from the blood of patients or healthy blood donors as a carrier, and the compound bovine bone morphogenetic protein is directly injected percutaneously into the injured part to exert the sustained release effect of the carrier and the bone morphogenetic protein to promote new bone growth and Fracture healing and accelerated wound repair. The invention has no immunogenicity and rejection reaction, and no adverse reaction after being implanted in the body. Fibrin is in a liquid state before use, and can be rapidly solidified in the body and can be shaped arbitrarily. At the same time, the hemostatic and adhesive effects of fibrin are beneficial to prevent the formation of local hematoma and provide a good local environment for bone regeneration and healing. The present invention has the advantages of definite therapeutic effect, wide application range, simple and convenient operation, safety and reliability confirmed by animal experiment and clinical experiment.

The invention discloses a method for restoring a river submerged plant. The method is characterized in that the submerged plant is used as a pioneer species, appropriate submerged plant is cultivated in the river, different growth conditions of the submerged plant in the river are controlled, submerged vegetation is reconstructed in the degraded river through appropriate maintenance management technology, and the survival rate of the reconstructed submerged vegetation reaches 60 to 70 percent. The local environment of the river water ecological system is improved by restoring the water plants of the river, the structure and the function of the river ecological system can be restored, the cost is low, simplicity, feasibility, low carbon and environmental friendliness can be realized, the benefit is remarkable, the method is suitable for the restoration engineering of the water vegetation of the polluted river and for the ecological reconstruction engineering of the polluted river water plant diversity and water ecological system.

The invention provides a Tibetan incense and a preparation method thereof. The Tibetan incense includes main ingredients and auxiliary materials, and the mass ratio of the main ingredients to the auxiliary materials is 5:3-5:1; the main ingredient is a mixture of elm bark powder and cypress powder, or cypress powder; auxiliary materials include: grass fruit, clove, Rhododendron microphyllum, cumin celery, cinnamon, cinnamon, inulin, grass safflower, sweet rhododendron and Yunnan camphor. The preparation method of Tibetan incense: the raw materials of the main material and the auxiliary material are pulverized respectively with a pulverizer, and then processed with a filter, a vibrating screen and a sieving machine to obtain the main material to be mixed and the auxiliary material to be mixed; the main material to be mixed is After soaking the materials and the auxiliary materials to be mixed with water, use a mixer to fully mix and stir; then use an incense making machine to produce a crude Tibetan incense, cut the crude Tibetan incense and dry it with a dryer to obtain a finished product. The Tibetan incense provided by the invention has pure and long-lasting fragrance, and has the effects of calming the nerves, improving intelligence, preventing influenza, and disinfecting and sterilizing.

The invention provides a body balm for pigs, which is composed of the following raw materials in weight ratio: talcum powder 30-40kg, montmorillonite 40-60kg, boric acid 5-10kg, salicylic acid 3-6kg, borneol 1- 3kg, zinc oxide 4-8kg. The present invention also provides a preparation method of the talcum agent, which includes the following steps: (1) respectively pulverizing boric acid, salicylic acid and zinc oxide to more than 100 meshes for use. (2) Take 10-15kg of talcum powder and put it into the mixer, then put in the borneol oil and mix in the mixer for 20-25 minutes to get the spare material. (3) Put all the montmorillonite, crushed boric acid, salicylic acid, zinc oxide and the remaining talcum powder and the spare materials in step (2) into the mixer and mix for 20-25 minutes, and then discharge after mixing Pack into bags. The invention protects the sow's abdomen, udder and hind legs and buttocks during the sow's production, avoids the sow's teat and vulva from directly contacting the ground with bacteria, causing the sow's postpartum triple syndrome, and absorbs the amniotic fluid around the newborn piglet , improve the survival rate of suckling pigs, and isolate and protect the tail docking wounds of suckling pigs to reduce bacterial infections.

The invention provides a pressure electric organ, the electricity power of which is generated by compressive movement on the ground during human walking. The invention also provides a power generation shoes under pressure of electronic components lines for rectification, charging, energy storage and lighting. The power generation shoes under pressure comprise a pressure electric organ, a bridge-typed whole wave rectification reactor, a electrolytic capacitor, a rechargeable battery, a light emitting diode, a power switching, a power socket and a shoes. The pressure electric organ used in the power generation shoes under pressure at least comprises two flexible magnetic cores, two coils, a permanent magnet, a elastic device, a permanent magnet guiding groove, a pressure transmission plate and a coil frame. The invention is a power-generating device with no mechanical transmission system, no noise and no requirement for lubrication.

The invention provides a rapid construction method for an over-wet soil roadbed. According to the natural water content, the compaction control water content, the seepage coefficient and the air inflow value of over-wet soil filling, the wind speed and the wind temperature are determined. Through rapid dehumidification equipment, the local environment of over-wet soil of a loose laid layer is effectively improved, the air temperature and the relative humidity of the local environment exceed the air inflow value of roadbed filling, meanwhile, the forward and reverse rotation stirring effect of an overturning and stirring wheel is adopted for assistance, and therefore the water content of the over-wet soil filling is rapidly reduced to the compaction control water content of over-wet soil. By the adoption of the method, the roadbed compaction quality is stable and reliable, the roadbed disease happening time is greatly delayed, and the use efficiency of a road surface is effectively improved; the technical problem that it is difficult to ted the over-wet soil within the set time to reach the compaction control water content under the rainy climate condition in South China due to the fact that the over-wet soil is high in water content is solved, the use rate of the over-wet soil is greatly increased, the construction efficiency of the over-wet soil is greatly improved, a construction period is shortened, and the manufacturing cost is saved; and the technological cost is low, the roadbed quality is good, and economic benefits are remarkable.
