The invention provides a device and a method of applying electrically functional acidic ionized water for cleaning and disinfecting items for family daily use, vegetables and fruits, vessels, surfaces of environmental objects, personnel and the like. The household electrically functional acidic ionized water generator includes a preparing device, a storage device and an automatic cleaning device of the electrically functional acidic ionized water. The preparing device for the electrically functional acidic ionized water includes an electrolysis device and a control device. The storage device includes an acidic water storage barrel and an alkaline water storage barrel. The automatic cleaning device includes a cleaning fluid storage barrel, a cleaning electromagnetic valve, a cleaning liquid check valve and a cleaning pump. The household electrically functional acidic ionized water generator and the control method utilize the electrically functional acidic ionized water rather than the chemical disinfectants for family daily use to achieve the cleaning and disinfecting items for family daily use, vegetables and fruits, vessels, surfaces of environmental objects, personnel and the like, and has the advantages of no residue after being used, and being pollution-free in the environment, low in cost, more significant in advantages compared with the traditional method of using chemical disinfectants.

The present invention belongs to the field of gene engineering technology of producing polypeptide medicine. By means of Bombyx mori nuclear polyhedrosis virus to recombine human endostatin gene, recombinant virus is obtained, which is preserved in China Microbe Strain Preservation Committee in the number of CGMCC No.0592. The virus is used in inocualting Bombyx mori larva and pupa for expression, and through separation to purity and freeze drying, injection and orally taken medicine is prepared. Animal experiment to mouse shows that the medicine has obvious effect of inhibiting tumor growth. The present invention provides one new method of preparing tumor treating medicine which low cost and high treating effect.

The invention relates to a fusion protein of anti-I type diabetes, and a preparation method thereof; the invention provides a fusion gene and a fusion protein which is expressed by the fusion gene; the fusion gene is nucleotide sequence which is shown by SEQ ID NO: 1. the invention also constructs an expression vector containing the fusion gene and a recombinant virus containing the expression vector; the fusion protein provided by the invention can be used for preparing the drugs for curing the I type diabetes.

The invention relates to a fusion protein for treating alzheimer disease, and a preparation method thereof. The invention provides the fusion protein for treating the alzheimer disease and also provides a nucleotide sequence expressing the fusion protein. The invention further provides an expression vector which contains the nucleotide sequence and a recombinant virus containing the expression vector. The recombinant virus refers to the recombinant virus which is stored in the General Microbiological Center of China Committee for Culture Collection of Microorganisms, with the storage code of CGMCC No.1795. The animal oral experiment shows that the provided fusion protein can generate a high-level antibody and becomes a novel method for preparing an oral medicine for treating the alzheimerdisease.

The invention relates to an electroplating liquid adopting nickel-cobalt tungsten sulfide nanocrystalline alloy electroplating for piston rings instead of hard chrome plating. The electroplating liquid comprises the following components according to the ratio: 100-165 g / l of nickel sulfate, 80-136g / l of cobaltous sulfate, 40-50 g / l of boric acid, 3-9 g / l of potassium chloride, 5-38 g / l of nano tungsten disulfide plating pulp, 3-5 g / l of a brightening agent and saccharin, 0.3-0.7 g / l of a wetting agent (lauryl sodium sulfate), and 20 g / l of sodium citrate. A production process of the electroplating liquid adopting nickel-cobalt tungsten sulfide nanocrystalline alloy electroplating for piston rings instead of hard chrome plating comprises the following steps: (1) checking before plating, (2) product hanging, (3) high-temperature degreasing, (4) electrolytic degreasing, (5) washing with deionized water, (6) activation with weak acid, (7) nickel preplating, (8) electroplating, (9) washing and recycling, and (10) heat treatment for removing hydrogen. Through the adoption of the electroplating liquid adopting nickel-cobalt tungsten sulfide nanocrystalline alloy electroplating for piston rings instead of hard chrome plating, and the production process of the electroplating liquid, which are provided by the invention, the overall performance and the life cycle of an electroplated layer can completely exceed those of the existing hard chrome plated layer, the environment is protected, and the energy is saved.

The treatment method for copper-containing acid sewage comprises: treating the sewage with barium sulphide or sodium sulfide to prepare a plurality of chemical products, such as barium sulfate, and can recycle acid liquid with H+ content more than 16% as iron rust remover. This invention has no pollution and well social and economic benefits.
