The invention belongs to the field of tumor treatment and the field of molecular immunology, and relates to an antibody for resisting human epidermal growth factor receptor 2 (HER2), as well as a medical composition and use of antibody, in particular to the antibody for resisting Her2 or an antigen binding fragment of the antibody for resisting Her2. The antibody for resisting Her2 comprises a first heavy chain and a second heavy chain, wherein according to the first heavy chain, a variable region of heavy chain (VH) of the first heavy chain comprises a complementarity-determining region (CDR) of which the amino acid sequence is SEQ ID No: 1-3, and the amino acid sequence of the CH of the first heavy chain is as shown in SEQ ID No: 7; according to the second heavy chain, a variable region of heavy chain (VH) of the second heavy chain comprises a complementarity-determining region (CDR) of which the amino acid sequence is SEQ ID No: 4-6, and the amino acid sequence of the CH of the first heavy chain is as shown in SEQ ID No: 8. Compared with the combination of two antibodies of trastuzumab and pertuzumab, the antibody disclosed by the invention has higher cell direct killing activity and higher antibody dependent cellmediated cytotoxicity (ADCC) activity; the complement-dependentcytotoxicity (CDC) activity of the two antibodies of trastuzumab and pertuzumab is equivalent to that of the antibody disclosed by the invention; the antibody disclosed by the invention adopts a structure of a normal antibody; and fucose is also knocked out, so that the ADCC activity is improved.

A pattern of conductive micro-wires as in a conductive pattern can be prepared using photo-lithography, or imprint technology. A photocurable composition is cured to form a pattern of photocured micro-channels. A conductive composition comprising metal nano-particles is added to the photocured micro-channels and excess conductive composition outside the photocured micro-channels is removed. The conductive composition in the photocured micro-channels is then dried at a temperature of less than 60 DEG C. The dried conductive composition in the photocured micro-channels is treated with hydrogen chloride vapor to form conductive micro-wires in the photocured micro-channels at a temperature of less than 60 DEG C. The outer surface of the conductive micro-wires is then polished in the presence of water, to form a micro-wire pattern.

Apparatus (100) and method are disclosed for removing or reducing the number of particles in an enclosed atmosphere during intracorporeal procedures. The apparatus comprises a housing (180) adapted to be placed against the body on which a procedure is to be formed, a first electrode (140) external to the housing for contacting the body, an elongated electrically insulated probe (130) extending from the housing (180) and being insertable into an intracorporeal body cavity (C) in which a procedure is to be performed, a second electrode (150) at the free end of the probe, and circuit means (110) for generating voltage between said first and second electrodes. The method comprises applying a voltage between the electrodes sufficient to cause local ionisation of particles within the body cavity such that they migrate away from the second electrode, thereby removing or reducing the number of particles generated during the procedure from the enclosed atmosphere at or around the site of the procedure.

The invention belongs to a technological method for removing iron and manganese in underground seawater out of marine culture water. The method for treating underground seawater used for aquiculture comprises the following steps of: quick oxygenation treatment: carrying out oxygenation treatment by an oxygenation appliance and maintaining the pH value of a water body to be 7.0-7.8, wherein [O2] is not less than 0.40[Fe2+]; biological oxidation treatment: hanging a hairbrush-shaped three-dimensional elastic filtering material of a PE material in a corridor of a reaction pool and forming a biologic filter membrane at the surface of a filler; detention treatment: detaining an insoluble substance in the elastic filtering material by the elastic filtering material in the reaction pool; precipitation treatment: precipitating in the corridor with the average water flow rate of 10-20m / h and the oxidation time of 1.5-3h; floatation treatment: treating by a floatation device, removing the fine particles of the iron and the manganese, carrying out secondary oxygenation and separating and removing most of insoluble compounds; and sand grain filtration treatment: filtering cinder and quartz sand by a two-section type filtering material filtration pool. The invention can ensure the content of dissolved oxygen in water, maintains the balance and the stability of microorganisms in the biologic filtering material and the water quality, has lower investment and running cost and increases the benefit of a culture system.

The invention relates to a method for purifying materials containing metal impurities, in particular to a method for removing at least one metal impurity of iron, sodium and calcium from hydrocarbon materials, which comprises that the materials containing metal impurities are mixed with flash gas (low grade gas) in a low-pressure separator of a hydrogenation unit to obtain the materials with a higher impurity removal rate by a fixed bed layer of filtering materials, absorbent or catalyst. Compared with the prior art, the method in the invention has mild operation conditions and high impurity removal rate, and can be used in processing various materials containing metal impurities.

The invention discloses a device and a method for removing water in coal, and belongs to the field of coal dehydration. Firstly, a coal sample is put into a reaction kettle and the reaction kettle isthen sealed; then high-pressure and high-temperature water vapor is introduced into the reaction kettle, and pressure maintaining is conducted; then a lower sealing piston is controlled to be opened to punish instantaneous ejection blasting, and the water vapor in the reaction kettle and water difficult to remove in the coal sample are discharged together. The reaction time is short, the operationis safe and stable and the cost is low. The device and method is suitable for large-scale production, so that the invention provides a new process breakthrough for further deep dehydration of coal.
