AI Technical Summary

Benefits of technology

This patented technology helps diagnose or treat patients with cirrhosis by measuring their levels of blood proteins called albumen concentrations during disease activity over time. By comparing these measurements against previous data from healthy individuals we found out which factors were associated more strongly than others when compared between them. These results showed how well they could identify people who are at risk of developing this condition early on before symptoms appear.

Problems solved by technology

This patents discusses different types of tests or techniques being developed over several decades ago but they all lack accuracy when it comes back from testing new samples without any evidence showing significant differences between them due to factors like age difference, gene mutations, environmental influences during disease development, etc., making accurate assessment difficult even if some were available. Therefore, this problem needs to be solved through novel approaches involving target identification and quantitative measurement instead of traditional histopatholog analysis.

Embodiment 1

[0027] Example 1: Verification of serum protein molecular markers in diagnosing the degree of liver fibrosis in chronic hepatitis B.

[0028]The serum protein molecular markers of the present invention collected 45 cases of liver fibrosis from chronic hepatitis B at different stages of liver fibrosis (Scheuer stage S0-S4, with an average of 10 cases in each group), all of which were confirmed by liver biopsy pathological diagnosis of fibrosis According to the degree of fibrosis, the S0 and S1 stages were classified as the early fibrosis group, and the S3 and S4 stages were classified as the advanced fibrosis group, and serum samples were collected. All serum samples were detected by proteomics detection technology (2DE-MS / MALDI-ToF MS), and the electrophoresis patterns were analyzed by ImageMaster software. The results show that the expression of the serum protein markers of the present invention differs by more than 2 times between the early fibrosis group and the late fibros...

Embodiment 2

[0032] Example 2: Application of Serum Protein Molecular Markers in Diagnosis of Liver Fibrosis in Chronic Hepatitis B

[0033] 1. Research objects: 100 cases of different stages of liver fibrosis (Scheuer stages S0-S4, with an average of 20 cases in each group) were collected in 2010.

[0034] 2. Research method: Collect 100 cases of chronic hepatitis B liver fibrosis cases with different stages of liver fibrosis (Scheuer stage S0-S4, with an average of 20 cases in each group). The S0-S2 stage was classified as the early fibrosis group, and the S3-S4 stage was classified as the advanced fibrosis group, and serum samples were collected. All serum samples were detected by serum ELISA to obtain the detection value of serum protein in the early fibrosis group and the advanced fibrosis group, and the statistical analysis between the groups showed statistical differences ( p <0.05), it is positive if it is consistent with the above diagnostic markers, otherwise it is negative.

Abstract

The invention belongs to the field of biomedicine, and relates to a non-traumatic serum protein molecular marker for diagnosing chronic hepatitis liver fibrosis. The protein marker provided by the invention is one or more of the following proteins: human serum glycosylation apoferritin-transferrin A chain, glycoprotein HC composite structure C chain, human complement component C3c, immune globulin MFc segment, human hemoglobin beta chain variant HbS wake, or protein A mimetic peptide tree-like ligand of IgG1Fc segment A chain (Herceptin). The invention also provides the detection method and application of the serum protein marker and a kit prepared according to the serum protein marker. In the invention, the serum protein molecular marker and related indexes such as mRNA and MicroRNA can be used for predicting the degree of chronic hepatitis liver fibrosis and can be used for prognosis judgment, treatment selection and curative effect evaluation.
