Problems solved by technology

[0006] HBV and other blood transfusion-related pathogens have an important impact on the blood safety of our country. For blood donors, on-site HBV related tests cannot be done. Only after the blood donation is completed, the five routine hepatitis B tests and HBV nucleic acid tests are concentrated. The disadvantage is that it takes a long time to wait for the test results, the detection method is complicated, and the reagent cost is high

Embodiment 1

[0060] Example 1. Method for Screening Metabolic Markers in the Blood of Hepatitis B Virus Infected Patients

[0061] 1. Take 30 cases of hepatitis B patients (HBG), the diagnostic criteria are positive for HBV nucleic acid test or two or three items of HBV enzyme immunoassay, excluding any of liver cancer and other infections or diseases, fasting serum in the morning, within 1 hour Store at -80°C within one hour. Serum from 30 cases of healthy physical examination (Con) of the same age should be stored at -80°C within 1 hour. After the samples are collected, they will be uniformly processed according to the following methods.

[0062] 2. Serum sample processing method for reversed-phase chromatography analysis

[0063] 1) Plasma / serum samples stored at minus 80°C were thawed on ice at 4°C for 30-60 minutes.

[0064] 2) Take 100ul of serum to a labeled 1.5ml centrifuge tube, add 600ul of a 3:1 volume ratio of chloroform:methanol mixed solution, sonicate for 1 hour, add 100ul ...

Embodiment 2

[0095] The targeted detection of a group of metabolic markers in patients with hepatitis B virus mainly comprises the following steps:

[0096] 1. Take 70 cases of hepatitis B patients (HBV), the diagnostic criteria are positive for HBV nucleic acid test or two or three positive for HBV enzyme immunoassay, exclude any one of liver cancer and other infections or diseases, fasting serum in the morning, 1 hour later Store at -80°C, 30 cases of healthy physical examination serum (Con) of the same age, and store at -80°C within 1 hour. After the samples are collected, they are uniformly processed according to the following methods.

[0097] 2. Serum sample processing method for reversed-phase chromatography analysis

[0098] 1) Plasma / serum samples stored at -80°C were thawed on ice at 4°C for 30-60 minutes.

[0099] 2) Take 100ul of serum into a labeled 1.5ml centrifuge tube, add 10ul of internal standard, add 600ul of chloroform:methanol 3:1, sonicate for 1h, add 100ul of water,...

Abstract

The invention belongs to the field of medical biotechnology and relates to the application of plasma metabolic markers in diagnosing or monitoring HBV. The object of the present invention is to provide the application of the metabolic marker in the blood in the preparation diagnosis or the reagent of monitoring hepatitis B virus, wherein, said marker is Creatinine, L-Proline, L-Arginine, PC (P-16: 0 / 20:4(8Z, 11Z, 14Z, 17Z)), PE(18:2(9Z, 12Z) / 18:1(9Z)), PC(o‑16:1(9Z) / 18:2( 9Z,12Z)), PC(P-16:0 / 18:1(11Z)), PE(18:2(9Z,12Z) / 18:0), PE(P-16:0 / 22:4( 7Z,10Z,13Z,16Z)), PE(P-16:0 / 22:4(7Z,10Z,13Z,16Z)), PE(P-18:0 / 18:2(9Z,12Z)), PE(18:0 / 18:1(11Z)), LysoPE(18:0 / 0:0), PE(16:0 / 18:1(11Z)), or PE(18:2(9Z, 12Z) / 16:0).

Description

technical field [0001] The invention belongs to the field of medical biotechnology and relates to the application of plasma metabolic markers in diagnosing or monitoring HBV. Background technique [0002] The cause of hepatitis B virus is hepatitis B virus, abbreviated as HBV, and hepatitis B virus is a DNA virus. Hepatitis B is an infectious disease mainly caused by hepatitis B virus. Clinically, the main manifestations are loss of appetite, nausea, upper abdominal discomfort, pain in the liver area, and fatigue. Some patients may have jaundice, fever and hepatomegaly accompanied by liver function damage. Some patients can become chronic and even develop into liver cirrhosis, and a few can develop into liver cancer. [0003] my country has a relatively high infection rate of hepatitis B virus. Before intervention measures such as hepatitis B vaccine vaccination and blood screening were implemented, the prevalence rate of hepatitis B virus surface antigen (HBsAg) in the p...
