The invention discloses a high-sensitivity enzyme-linked immunoassay method. The method comprises the following steps of: according to a characteristic of specific binding of a measured object and an antibody (antigen), marking the antigen or the antibody and the corresponding antibody or antigen by a corresponding enzyme under a specific condition so as to achieve an absorption combination process, and indirectly representing the concentration of the measured object by the catalytic speed of the marked enzyme about a substrate. According to the high-sensitivity enzyme-linked immunoassay method provided by the invention, a problem of insufficient sensitivity of a regular enzyme-linked immunoassay based on a spectrophotometry is effectively overcome, and the high-sensitivity chemical oscillation dynamics detection and enzymatic dynamics analysis with specificity and flexibility amplification action are combined by utilizing an antibody-antigen specificity combination principle, so that the problems of low chemical oscillation selectivity and incapability of carrying out qualitative determination are overcome, thus the chemical oscillation in combination with the enzyme-linked immunoassay method can be used for qualitative and quantitative determination of substances such as medicine and pesticide micromolecules, antibody, antigen, specific protein, nucleic acid, disease factors and the like.

The invention discloses a construction method, system and application for a disease data analysis and processing model. The method comprises the steps of collecting disease original data and unifyinga data format; preprocessing the collected disease original data to form a large-capacity structured sample matrix; using the large-capacity structured sample matrix as data, and screening out an attribute set needed for model training to form a training sample matrix; using the training sample matrix as data, and constructing and training a best network model for disease prediction based on a feature data training method and a different error back propagation algorithm; evaluating model construction of non-unbalanced data and unbalanced data based on the correct rate and the F value; constructing a data validation mode to determine the validity of user data. According to the construction method, an auxiliary support is provided for medical diagnosis by excavating factors with the influence on disease and constructing an auxiliary diagnosis model.

The invention discloses application of recombinant human Rho kinase to preparation of medicaments. Recombinant human Rho-associated coiled-coil forming protein kinase (ROCK)1 fragment protein (RP1 for short) has the activity of the Rho kinase, so that corresponding substrates can be phosphorylated; the RP1 has the effect of contracting blood vessels, and the functional regulation effect of the blood vessels is related to the endothelium of the blood vessels, is blocked by a calcium channel blocking agent and is inhibited by Fasudil serving as an Rho kinase inhibitor; after entering bodies of animals in an injection mode, the RP1 can rise the blood pressure of the animals and has the characteristic of quick response; and the RP1 has the effect of accelerating the heart rate of the animals under the condition of providing high dose in the injection mode, and has the effect of improving the blood vessel function reduced due to various factors including disease factors. The RP1 can be applied to the preparation of medicaments for relieving, preventing and / or treating cardiovascular and cerebrovascular diseases or symptoms which are caused by various factors including disease factors and are related to the reduction of the blood vessel function.

The invention discloses an improved cloud model based on an entropy algorithm and a fault tree risk analysis method for ancient buildings, including the following steps: (1) collecting structural information of old wooden structures and establishing a fault tree, and the lowest layer of the fault tree is the disease of the basic unit (2) The disease factors are qualitatively evaluated by n experts, and the qualitative evaluation of each expert is converted into an evaluation cloud, and then the n evaluation clouds are synthesized into a disease factor cloud through an entropy-improved comprehensive cloud algorithm; (3) The disease factor cloud is synthesized upward according to the fault tree through the weighted comprehensive cloud model algorithm; (4) The risk level of the old wooden structure building is determined according to the expected value of the evaluation unit cloud at the top of the fault tree. The invention introduces the cloud model to quantitatively describe the safety evaluation data of old wooden structures, combines the advantages of the fault tree to describe the risk relationship and the fault system architecture, calculates the risk levels of each basic cause unit that may cause a fault and the overall structural unit, and provides risk ranking .

The present invention relates to a composition for preventing and treating gastrointestinal diseases by using Litsea japonica, and specifically, to a composition for preventing and treating gastrointestinal diseases, containing essential oils extracted from Litsea japonica fruit as an active ingredient. According to the present invention, the essential oils extracted from Litsea japonica fruits (pure fruit, seed fruit, and seeds) and used as the active ingredient of the composition for preventing and treating gastrointestinal diseases have been confirmed to have excellent effects in an efficacy evaluation for relieving gastrointestinal diseases caused by Helicobacter pylori, which is a gastrointestinal disease factor, physical factors induced by stress, and chemical factors induced by indomethacin. Therefore, the essential oils extracted from Litsea japonica fruit (pure fruit, seed fruit, and seeds) are useful for preventing and treating gastrointestinal diseases caused by various factors.
