DNA微陣列方法鑒別七氟醚和丙泊酚麻醉下誘導(dǎo)的基因表達情況
[Abstract]:Coronary artery bypass grafting ( CABG ) is an effective method for coronary artery bypass grafting ( CABG ) and coronary artery bypass grafting ( OPCABG ) for coronary artery bypass grafting ( CCABG ) and off - pump coronary artery bypass grafting ( OPCABG ) . OPCABG has been widely used in the treatment of coronary heart disease . However , OPCABG is widely used in the treatment of coronary heart disease .
The results showed that the levels of IL - 10 and IL - 1 receptor in patients with coronary artery bypass grafting could be reduced by lowering the level of myocardial ischemia induced by myocardial ischemia .
Although a large number of researches have been conducted to prove that the heptafluoroether and propofol have an effective cardioprotective effect , the potential mechanism of myocardial protection is still unclear . The research uses bioinformatics technology to analyze the specific differential expression gene of the inhalation heptafluoroether treatment group , the specific differential expression gene of intravenous propofol treatment group and the two groups of common differential expression genes , and the three groups of differentially expressed genes are analyzed .
Then we performed functional annotation and analysis on three groups of differentially expressed genes .
In order to find out the mechanism of myocardial protection in anesthesia and intravenous injection of propofol from more detailed molecular interaction , this paper lays a theoretical foundation for the protection of myocardium in the perioperative period of CABG . The results are as follows :
1 . The expression profiles of myocardial tissue microarray in coronary artery bypass grafting ( GSE4386 ) were downloaded from GEO ( Gene Expression Omnibus ) . The expression profiles of differentially expressed genes induced by propofol group and propofol group were screened by Affy packet in R language .
2 . Compared with the differentially expressed genes screened in the group of propofol anesthesia and intravenous anesthetic propofol , the specific differential expression genes were obtained under the induction of the inhalation of heptafluoroether , 290 of which were specific differential expression genes and 275 differentially expressed genes which were induced by intravenous anesthetics .
There was significant difference in the expression level of propofol in propofol group ( P = 0.02206 ) .
There was a difference between the two groups in the two groups ( P = 2.98e - 14 ) , that is , the results of the analysis were consistent with the screening results of the differentially expressed genes .
3 . GO analysis was carried out on the specific differential expression gene of the group of heptafluoroether and propofol by the DAVID online tool to enrich the key biological processes involved in these differences .
The specific differential expression genes in propofol treatment group were most significantly involved in response to organic matter ( n = 45 ) . The comparison between the two groups of specific differential expression genes and the genes annotated by the common differential expression genes was compared with the COG direct homologous cluster database . The COG functional classification of three types of differential expression genes from cellular _ component , molecular _ function and biological process was very similar .
4 . The functional modules of the specific differential expression gene were identified as : CISH , PTPN1 , SOCS1 , IL15RA , RCAN1 , IL6R , FOSB , JUNB and TNFAIP3 .
In this study , the cardioprotective effects of heptafluoroether and propofol in CABG were systematically reviewed from the molecular biology perspective . The results showed that the combination of the inhalation anesthetic and propofol had a synergistic effect in the protection of cardiac muscle .
Subject innovation and significance
In this study , we analyzed the specific differential expression gene , intravenous propofol treatment group specific differential expression gene and two groups of different expression genes , and then analyzed the functional characteristics of the three groups of differentially expressed genes , and then analyzed the functional enrichment of the three groups of differentially expressed genes .
The significance of this study is to elucidate the role and key role of propofol and propofol propofol in coronary artery bypass grafting ( CABG ) in coronary artery bypass grafting ( CABG ) , and provide theoretical basis for exploring the possible role of propofol in the operation .
