The invention provides a kit and a method for identifying the infection category of a sample to be detected by detecting host peripheral blood gene expression, the kit simultaneously detects expression levels of two groups of genes in the sample to be detected, the first group is genes for identifying bacterial infection, the group of genes are S100P gene, ANXA3 gene, ITGAX gene and ITGAM gene, and the group of genes are S100P gene, ANXA3 gene, ITGAX gene and ITGAM gene. The first group is a gene for identifying fungal infection, the second group is a gene for identifying fungal infection, the group comprises an IFI44L gene, an IFIT3 gene, an IFIH1 gene, an LY6E gene, an IFIT1 gene and an IFITM3 gene, and whether the sample to be detected is bacterial infection, fungal infection, simultaneous bacterial and fungal infection or non-bacterial and non-fungal infection is determined by detecting the two groups of genes. According to the invention, ten genes expressed in peripheral blood are screened out, so that the detection cost and accuracy for distinguishing bacterial infection and virus infection can be kept at a balance point, and finally, clinical application can be realized.

This invention belongs to the field of biological detection technology, and particularly relates to a reproductive tract HPV-mRNA-E6 / E7 detection system and method based on nanopore sequencing. The system includes a sample pretreatment module, an RNA extraction and purification module, a reverse transcription module, a nanopore sequencing module, and a bioinformatics analysis module. The method includes the following steps: (1) reproductive tract sample collection and pretreatment; (2) extraction and purification of HPV-mRNA in the sample; (3) reverse transcription of the purified HPV-mRNA into cDNA; (4) nanopore sequencing of the cDNA to obtain raw sequencing data; (5) filtering, comparing, and annotating the sequencing data through the bioinformatics analysis module to achieve HPV type identification and quantitative analysis of E6 / E7 gene expression levels. This invention utilizes the advantages of nanopore sequencing, such as long read length and real-time detection, combined with the specificity of E6 / E7 mRNA as a biomarker of active infection. It can directly detect latent and active HPV infection, improve detection sensitivity, accurately distinguish infection types, and shorten the detection cycle. It enables rapid, accurate, and high-throughput detection of active HPV infection in the genital tract, providing reliable technical support for early screening, disease monitoring, and prognostic assessment of HPV-related diseases such as cervical cancer.

The present application relates to the technical field of pest image analysis, and particularly relates to an AI image recognition and grading method for field crop leaf diseases and pests, comprising the following steps: under the irradiation of a fixed light source in a field, multiple polarized reflection images are synchronously collected at a predetermined angle interval around the crop leaves; a pixel polarization degree matrix of a leaf area in each polarized reflection image is extracted; the pixel polarization degree matrix is input into a polarization transmission model, and an abnormal cuticle coefficient map is output, and a region exceeding a preset abnormal threshold in the abnormal cuticle coefficient map is marked as a highlighted display region; an infection type template library is matched according to a distribution mode of the highlighted display region in the abnormal coefficient map; an infection intensity value is calculated in combination with a diffusion gradient of the highlighted region, and a disease and pest grade is output. The present application characterizes the optical mutation region boundary of a lesion area, not only improves the physical interpretation of disease detection, but also provides a distinguishable feature space for different infection mechanisms (such as a fungal growth layer and a pest piercing point).

This invention provides a kit and method for identifying the infection type of a test sample by detecting gene expression in host peripheral blood. The kit simultaneously detects the expression levels of two groups of genes in the test sample. The first group consists of genes for identifying bacterial infection, including the S100P, ANXA3, ITGAX, and ITGAM genes. The second group consists of genes for identifying viral infection, including the IFI44L, IFIT3, IFIH1, LY6E, IFIT1, and IFITM3 genes. Detection of these two groups of genes determines whether the test sample is infected with bacteria, virus, a combination of bacteria and virus, or neither bacteria nor virus. This invention screens out 10 genes expressed in peripheral blood, achieving a balance between the cost and accuracy of distinguishing between bacterial and viral infections, ultimately enabling clinical application.

A computer-implemented method determines an optimal drug dosing regimen to treat a patient against a drug-sensitive pathogenic agent responsible for infection. The method obtains patient data and drug data, including the drug, administration route, adaptation type (priori or posteriori), and a drug treatment regimen. The method includes determining values for pharmacokinetic parameters for efficacy (PPE) and pharmacokinetic parameters for toxicity (PPT) from the patient and drug data using population pharmacokinetic models when PPE and PPT are not obtained directly from measurement concentration(s). The method includes obtaining infection data, including parameters selected from the documentation of infection, localization, infection type, identified pathogen, susceptibility, and minimum inhibitory concentration. The method includes determining an efficacy target for the drug from the infection data and a target at risk of toxicity. The method includes determining an optimal dosing regimen by comparing PPE with the efficacy target and PPT with the risk of toxicity target.
