Embodiment 1

[0026] In this example, a set of primer pairs was designed and synthesized, and based on the primer pairs, a method for detecting the G-201A genotype of the CXCL10 gene associated with the progression of hepatitis B was designed.

[0027] 1. Genomic DNA extraction

[0028] Genomic DNA of peripheral blood leukocytes was extracted by the phenol / chloroform method in the field.

[0029] 1) Take sodium citrate or EDTA-Na 2 5ml of anticoagulated whole blood (try not to use heparin for anticoagulation), put in a 50ml capped centrifuge tube;

[0030] 2) Add 3-5 times the volume of cold distilled water, invert and mix repeatedly, place in ice for 5 minutes, and centrifuge at 2000rpm at 4°C for 20 minutes;

[0031] 3) Slowly decant the supernatant, add pre-cooled 0.1% Triton-X100 (same volume as above) to the precipitate, gently mix the precipitate, centrifuge as above, and discard the supernatant;

[0032]4) Add 4ml of lysate (50Mm Tris-Cl-10mM EDTA, pH 8.0) to the precipitate, brea...

Embodiment 2

[0046] In this example, the method established in Example 1 was used to analyze the G-201A genotype of the CXCL10 gene of 1147 cases of chronic progressive hepatitis B patients and 1253 cases of asymptomatic HBV carriers.

[0047] 1. Test object:

[0048] This study included 1147 chronic progressive hepatitis B patients and 1253 asymptomatic HBV carriers (collected from Beijing Hospital of Infectious Diseases [613 copies] and Chongqing Southwest Hospital [1787 copies] from February 2001 to March 2006). ]). All HBV-infected patients were positive for HBsAg and anti-HBc IgG for at least 12 months. All carriers underwent liver function test, serum marker detection, ultrasound / computed tomography imaging during the study period, and 376 cases (15.7%) underwent liver biopsy. All subjects had no serological evidence of HCV, HDV, and HIV co-infection. While collecting tissue specimens or blood samples, each research subject signed an informed consent form and provided detailed cli...

Abstract

The invention relates to a detection method of G-201A locus of predisposing gene CXCL10 relevant to progression of chronic hepatitis type B disease course. The method is a PCR-RFLP method (namely polymerase chain reaction-restriction fragment length polymorphism method). The invention further relates to a kit for detecting the predisposing locus and the application thereof. In addition, by linking the G-201A locus of gene with the occurrence risk of the progression of chronic hepatitis type B disease course, the invention determines CXCL10 as a novel predisposing gene of the progression of chronic hepatitis type B disease course and provides new genetic counseling content for people who are chronically infected with hepatitis type B about the early warning of disease severity.

Description

technical field [0001] The invention relates to the individual susceptibility and genetic detection method of the progress of the disease course of chronically infected patients of hepatitis B virus (HBV). Specifically, the present invention relates to a genotype detection method of the susceptibility gene CXCL10 related to the progress of the disease course of HBV chronic infection patients. The present invention further relates to a detection kit for the above-mentioned susceptibility gene genotype, and the application of the kit. In addition, the present invention also relates to the application of the above-mentioned detection method and susceptibility gene in early warning and genetic counseling of HBV chronically infected patients. Background technique [0002] HBV is the most common causative agent of acute or chronic hepatitis worldwide, especially in some Asian and African countries. During chronic HBV infection, HBV-specific CD8 + T cell immune responses cause l...
