Embodiment 1

[0056] Example 1 The method of the present invention was used to detect the expression levels of 17 genes in 24 samples at the same time. (15 genes are cardiovascular disease-related genes, β-ACTIN and human glycerol kinase genes are reference genes for analysis)

[0057] (1) Design reverse transcription primers and PCR primers for amplifying the target gene, see Sequence 1 to Sequence 18 in Table 1 for details.

[0058] (2) Take out the prepared multiple reaction RT primer working solution and 200nmoL / L PCR primer from the refrigerator, and amplify the target fragment. The reverse transcription reaction system for 24 people is shown in Table 10.

Abstract

The invention relates to a method for simultaneously detecting 17 genes. Sequences of mRNA of interleukin-1beta (IL-1beta, NM-000576, etc.) and sapiens glycerol kinase (NM-203391) are referred to on PUBMED; a reverse transcription primer and a PCR primer are designed; reverse transcription, PCR amplification and capillary electrophoresis are performed; and quantitative analysis is performed by a Gexp analysis system. The detection method not only comprises a quality control gene of a kanamycin resistance gene (Kan, R) for monitoring the reaction system, but also designs two amplified products for L-selectin which are used to detect the stability of the reaction system. The invention has the advantages of small sample size required, high sensitivity and accuracy. The method analyzes the properties and components of an atherosclerotic plaque by detecting the expression situation of peripheral blood related genes, and establishes a technical platform for batch screening of differential genes between cardiovascular diseases and controls.

Description

technical field [0001] The invention relates to a method for simultaneously detecting 17 genes. It belongs to the field of medical molecular biology. Background technique [0002] In recent years, the prevalence of coronary atherosclerotic heart disease (CAD) has been increasing year by year, and a considerable proportion of patients have no clinical symptoms in advance. Coronary atherosclerosis is paid clinical attention only when it develops to a certain extent and causes myocardial ischemia. The early diagnosis of coronary atherosclerosis, that is, the preclinical diagnosis that has not caused myocardial ischemia, is important for the prevention of clinical events of coronary heart disease. Whether it is early preventive intervention and treatment in high-risk groups is of great significance. Little is known about coronary atherosclerosis in asymptomatic individuals with high-risk factors. [0003] Studies have shown that metabolic disorders of blood lipids and changes...
