Problems solved by technology

[0003] BCS can cause liver damage, portal hypertension, and even serious complications such as liver cirrhosis, liver failure, and upper gastrointestinal bleeding.
The early clinical manifestations of BCS patients are hidden and non-specific, and there is no effective method for early diagnosis and treatment. Most of the patients are in the late stage when they see a doctor, and the clinical manifestations are complex and diverse, which is easy to cause misdiagnosis and mistreatment.
Domestic research on BCS is mostly focused on clinical treatment, compared with epidemiological and etiological research lagging behind, lack of national census and etiological research

Embodiment 1

[0038] Example 1 Screening of differentially expressed genes

[0039] 1. Research objects and sample collection

[0040] (1) Research objects: 3 patients with Budd-Chiari syndrome and 5 normal volunteers.

[0041] (2) Sample collection: The subjects were required to fast for at least 12 hours, and at room temperature from 7:00 to 8:00 in the morning of the next day, 10ml of venous blood was drawn into ethylenediaminetetraacetic acid (EDTA) anticoagulant tubes, and 3 times the volume of red blood cells was added for lysis. solution, mix well, place at room temperature for 10 minutes, and centrifuge at 10,000 rpm for 1 minute. Discard the supernatant thoroughly and collect the white blood cell pellet. Add 1ml TRIzol to every 100-200μl blood collected white blood cell pellet, and freeze it at -80℃ for later use.

[0042] 2. Acquisition of total RNA

[0043] Total RNA in blood leukocytes was extracted using TRIzol according to conventional methods.

[0044] 3. RNA concentrati...

Embodiment 2

[0057] Example 2 Large sample verification screened out differentially expressed genes

[0058] The MYOM2 gene was selected for validation.

[0059] 1. Sample collection

[0060] According to the method in Example 1, 50 peripheral blood samples were collected from Budd-Chiari syndrome patients and 50 normal people.

[0061] 2. Validation at the mRNA level

[0062] 2.1 Extraction of total RNA from blood

[0063] Step is with embodiment 1.

[0064] 2.2 Reverse transcription

[0065] Reverse transcription using Primescript 1 st strand cDNA synthesis kit kit, the operation steps are as follows:

[0066] (1) Add the following reaction liquid in the microcentrifuge tube, as shown in Table 1:

[0067] Table 1 Reaction liquid

Abstract

The invention discloses application of MYOM2 to the preparation of a diagnostic tool for the Budd-Chiari syndrome. Through detection, in the blood of a patient suffered from the Budd-Chiari syndrome, the expression of an MYOM2 gene is obviously lowered; the Budd-Chiari syndrome can be diagnosed through detecting the expression of the MYOM2 gene. According to a diagnostic method provided by the invention, the blood of a testee is used as a to-be-tested object; the pain of biopsy carried out on the testee is avoided; therefore, the diagnostic application of the MYOM2 can be suitable for being clinically widely applied.

Description

technical field [0001] The invention relates to the field of disease diagnosis, more specifically, the invention relates to the application of MYOM2 in the diagnosis of Budd-Chiari syndrome. Background technique [0002] Budd-Chiari syndrome (BCS) is a posthepatic portal syndrome characterized by obstructive lesions of the inferior vena cava above the hepatic vein and / or its opening, often accompanied by inferior vena cava syndrome. hypertension. From a global perspective, the incidence of BCS is low, and its etiology has obvious regional differences. In western countries, BCS with hepatic vein obstruction is more common, and most of them have clear etiologies, such as oral contraceptives, pregnancy, and blood diseases. It has been reported in the literature that hepatic venous BCS is related to blood hypercoagulability and hepatic vein thrombosis caused by gene mutations; while in Asia and South Africa, IVC obstructive BCS is more common, and the etiology is mostly unclear...
