AI Technical Summary

Problems solved by technology

The TAAs used in most previous related studies were identified from other types of tumors rather than esophageal cancer, and their sensitivity and specificity in the detection of esophageal cancer still need to be fully evaluated; although some studies Esophageal cancer-associated tumor antigens have been identified using proteomic techniques, but less comprehensive and in-depth evaluation of their elicited autoantibodies as early immunodiagnostic markers for esophageal cancer

Embodiment 2

[0089] Embodiment 2: the diagnostic value analysis of test strip

[0090] Use the test strip prepared in Example 1 of the present invention to detect the serum samples of pathologically confirmed early esophageal cancer patients and normal people, and evaluate and analyze the value of the test strip of the present invention for early esophageal cancer screening and diagnosis.

[0091] 1. Sample source

[0092] Serum samples from 100 patients with early-stage esophageal squamous cell carcinoma and 100 normal controls were collected from the First Affiliated Hospital of Zhengzhou University. Sera from 100 patients with esophageal cancer (esophageal cancer group) were obtained from newly diagnosed patients who were pathologically confirmed and did not receive any radiotherapy or chemotherapy. There were 50 males and 50 females, with an average age of 59.1±6.8 years, and the age range was 40 to 80 years; 100 cases were normal Human serum (control group) came from outpatient healt...

Abstract

The invention belongs to the field of medical biotechnology and discloses a test strip for joint screening of early esophageal cancer. The test strip includes a binding pad and a chromatography pad, and the binding pad is coated with a mouse anti-human IgG monoclonal antibody and a rabbit IgG monoclonal antibody. Antibodies, mouse anti-human IgG monoclonal antibody and rabbit IgG monoclonal antibody all have detectable markers; there are three detection lines and one quality control line on the chromatography pad, and the detection antigens coated on the three detection lines are KPNA6 protein, PDE1A protein, CASK protein; the quality control belt is coated with goat anti-rabbit IgG. The test strip of the present invention combines KPNA6 protein, PDE1A protein, and CASK protein, three tumor-associated antigens, as markers for early esophageal cancer screening, and is used to detect the expression levels of autoantibodies of KPNA6, PDE1A, and CASK in serum, which can effectively Detection of esophageal cancer, especially early esophageal cancer, has greatly improved the detection rate of early esophageal cancer.

Description

technical field [0001] The invention belongs to the technical field of medicine and biology, and in particular relates to a test strip for joint screening of early esophageal cancer. Background technique [0002] Esophageal cancer is one of the most common malignant tumors of the digestive system in humans. The incidence of esophageal cancer ranks eighth among all malignant tumors worldwide, and its case fatality rate ranks sixth among cancer deaths. my country is a country with a high incidence of esophageal cancer in the world, and the tissue type is mainly squamous cell carcinoma (esophageal cancer in the present invention refers to esophageal squamous cell carcinoma, i.e. esophageal squamous cell carcinoma). According to the latest data from the "China Tumor Registration Annual Report" published in 2018, my country's esophageal cancer ranks sixth in the incidence of malignant tumors and fourth in death, posing a serious threat to people's quality of life and family happi...
