The application discloses a microorganism marker composition of an allergic population based on enterotype typing and application thereof in preparation of a reagent or kit for identifying allergic diseases. The application also discloses a kit for identifying allergic diseases. The application further discloses a method for constructing an allergic prediction model based on enterotype typing and application thereof in construction of a system for judging allergic risks of samples. The application first proposes an allergic prediction model based on enterotype stratification, classifies samples through enterotype typing, and then predicts allergic risks of the samples by using corresponding machine learning models. The application can detect allergic risks of children by a non-invasive and non-intrusive method, and only needs feces of the children. The application provides a new technical basis for future research on allergic diseases of children and a new non-invasive and non-intrusive method for detection of allergic diseases of children.

Disclosed is use of Cordyceps sinensis MBF1 in the preparation of a health product or drug for preventing and / or treating radiation injury, particularly in the preparation of a health product or drug for preventing and / or treating intestinal radiation injury and / or hematopoietic radiation injury caused by ionizing radiation. Cordyceps sinensis MBF1 can significantly ameliorate symptoms caused by intestinal radiation injury, such as shortened colon length, small intestinal tissue injury, and elevated small intestinal inflammation level, ameliorate symptoms caused by hematopoietic radiation injury, such as reduced white blood cell count, reduced spleen index, and / or reduced thymus index, and can be used as a health product or drug for preventing and treating radiation injury, particularly intestinal radiation injury and / or hematopoietic radiation injury, thereby addressing the current lack of effective health products or drugs for the clinical treatment of intestinal radiation injury and / or hematopoietic radiation injury. In addition, the present disclosure provides a new idea and strategy for developing an anti-radiation injury health product or drug and demonstrates important scientific significance and clinical application value.

The present application belongs to the field of agricultural mechanization equipment, and proposes a greening auxiliary planting device based on different mountainous conditions, which comprises a hand-held device and a walking device. The walking device comprises a front wheel mechanism, a rear wheel mechanism and a bottom bridge. A pair of ground grabbing devices are arranged at the tail of the bottom bridge. An intestinal type vehicle body is arranged above the front wheel mechanism and the rear wheel mechanism. A rotary clamping device is arranged at the front end of the intestinal type vehicle body. The rotary clamping device comprises a plurality of interval distributed lower clamping openings. A tail hoop is arranged at the position close to the rear end of the intestinal type vehicle body. A group of telescopic devices are arranged on both sides of the tail hoop. The telescopic device comprises a fixed cantilever, a movable cantilever, a plurality of upper clamping pieces and a righting clamping piece. The movable cantilever is provided with a control device arranged on the hand-held device for controlling the telescopic device to stretch and retract. The present application has the advantages of reasonable design, good mobility, better mountain passability, being conducive to auxiliary planting and improving work efficiency.

The application relates to the technical field of intestinal typing, and discloses an intestinal typing method based on intestinal microorganism flora structure, which comprises the following steps: acquiring intestinal flora sequencing data; the intestinal flora sequencing data comprises intestinal flora 16s amplicon data and metagenome sequencing data; performing quality control and species annotation analysis on the intestinal flora sequencing data to obtain first relative abundance information of sample intestinal flora; screening according to the first relative abundance information and a chi-square verification method to obtain intestinal flora characteristic data; and inputting the intestinal flora characteristic data into a preset intestinal type prediction model to perform intestinal type prediction. The 16s amplicon and metagenome sequencing data are processed and analyzed to obtain intestinal flora characteristic data, and a preset intestinal type prediction model is used to perform intestinal flora typing to predict the intestinal type. Compared with a clustering method, a machine learning method can improve the efficiency and accuracy of intestinal type identification, can perform intestinal type identification on single and multiple samples, and is not limited to single-source samples.

The application discloses a targeted nutrient source mining method based on beef cattle intestinal type-host gene interaction, and particularly relates to the field of biological information data processing, and is used for solving the problems of lack of molecular mechanism verification and poor targeting of existing nutrient source development. First, based on the microbiome and transcriptome data, the nutrient-related intestinal type is divided, and the co-expression network is constructed to screen the host co-expression specific genes driven by the specific intestinal type. Then, the model of the group metabolite ligand set and the host protein receptor is established, the molecular conformation search and the Gibbs free energy calculation are performed, and the high-activity targeted effect factor is screened based on the physical affinity. Finally, the targeted effect factor is used for traversing matching and quantitative screening of natural raw material liquid chromatography-mass spectrometry data, and a targeted nutrient source recommendation list for the specific intestinal type is generated. The application combines multi-omics correlation analysis and molecular thermodynamic verification, and constructs a precise development closed loop from micro mechanism analysis to macro raw material matching.

Disclosed is use of Cordyceps sinensis in the preparation of a health product or drug for preventing and / or treating radiation injury, particularly in the preparation of a health product or drug for preventing and / or treating intestinal radiation injury caused by ionizing radiation. Specifically, Cordyceps sinensis can significantly ameliorate symptoms caused by intestinal radiation injury, such as weight loss, shortened colon length, elevated ROS content in blood and / or small intestine, elevated inflammation levels in blood and / or small intestine, and small intestine tissue injury.
