Recombinant low-virulent vaccine strain of chicken infectious bursal disease viruses (IBDV) and application thereof

The invention discloses a recombinant low-virulent vaccine strain of chicken infectious bursal disease viruses (IBDV) and application thereof. In the invention, a major protective antigen gene VP2 of an epidemic superhigh virulent strain is cloned, the nucleotide of the gene VP2 is modified by mutation and then used for replacing a corresponding segment of a Gt genome of a low-virulent strain of the IBDV, so that the infectious clone of a recombinant genome of the IBDV is constructed, and the recombinant low-virulent vaccine strain is saved and identified by using an IBDV reverse genetic operation system. The microbial collection number of the vaccine strain is CGMCC No.3749. The recombinant low-virulent vaccine strain of the invention has high replicability, genetic stability and safety. The immune effect of the low-virulent vaccine strain of the invention is as good as that of the medium-virulent vaccine strain, but is superior to that of the low-virulent vaccine strain. The biological safety of the low-virulent vaccine strain of the invention is superior to that of the medium-virulent vaccine strain. As the vaccine strain, the recombinant low-virulent vaccine strain of the invention has the characteristics of high efficiency and low toxicity, is a good candidate vaccine strain and can be used for controlling chicken infectious bursal disease.

Expressway intelligent operation system through coordination of automobiles and pathways and using method

The invention discloses an expressway intelligent operation system through coordination of automobiles and pathways and a using method. The system comprises two pathways which are arranged at the ascending side and the descending side of an expressway in the same direction, and at least one veering rail is connected between the pathways at the two sides, the veering rail is communicated with the pathways, and the system further comprises transportation carts which can load automobiles and run on the pathways, control panels, control chips, locating devices, and a central running system, wherein the control panels, control chips, and locating devices are arranged on the corresponding transportation carts, and the central running system is used for regulating and controlling all the transportation carts. Through the method of combining the automobiles with the pathways, the purpose of conducting door-to-door transportation can be achieved, and the transportation time is saved; the central running system is utilized to intelligently regulate and control all the transportation carts, and thus unmanned driving is achieved; after getting rest in one transportation cart and getting off the transportation cart, a driver keeps a better mental state to drive on a common expressway, and thus an car accident caused by fatigue driving is avoided; it is guaranteed that green-hand drivers can be helped to safely drive on the expressway.

Traditional Chinese medicine for treating senile dementia and preparation method of fluid extract of traditional Chinese medicine

The invention relates to a traditional Chinese medicinal preparation, and particularly relates to a traditional Chinese medicine for treating senile dementia and a preparation method of a fluid extract of the traditional Chinese medicine. The traditional Chinese medicine is prepared from the following raw medicinal materials in parts by weight: 15-20 parts of ginseng, 7-10 parts of lycium barbarum, 8-12 parts of herba cistanche, 5-10 parts of rhizoma acori graminei, 12-15 parts of ophiopogon root, 8-12 parts of poria cocos, 10-15 parts of polygala tenuifolia, 2-5 parts of astragalus membranaceus, 5-7 parts of polygonatum kingianum, 8-10 parts of cordyceps sinensis, 2-5 parts of polygala tenuifolia and 2-5 parts of alpinia oxyphylla. The preparation method of the fluid extract of the traditional Chinese medicine comprises the following steps: (1) grinding the raw materials into fine powder, diluting with 70% ethanol serving as a solvent and water, collecting primary filtrate by adopting a percolation method, and keeping on percolation until the filtrate is colorless or slightly yellow in visual inspection; (2) collecting filtrate, concentrating in reduced pressure to obtain thick paste, and adding the primary filtrate to obtain a mixed solution; (3) keeping on diluting the mixed solution, standing and filtering to obtain the fluid extract. The traditional Chinese medicine and the fluid extract thereof have the advantages of enhancing the immunity of old people, dilating blood vessels, inhibiting platelet aggregation, reducing blood viscosity, and improving blood circulation and brain perfusion flow.
