ABSTRACT
Objective To investigate the correlation between Helicobacter pylori (Hp) infection and blood lipid metabolism and atherosclerosis.Methods From October 2015 to October 2020,200 cases of Hp positive subjects were observed as observation group and 200 cases of Hp negative subjects as the control group,all subjects were blood lipid levels of vascular ultrasound and other related checks.Results The levels of total cholesterol (TC) (5.68± 1.46 mmol/L),triglyceride (TG) (1.58 ± 0.76 mmol/L) and low density lipoprotein cholesterol (LDL-C),and the difference was statistically significant (t=6.12,7.69,5.64,all P＜0.05).The detection rate of carotid atherosclerotic plaque in the observation group was 66.00 ％,which was significantly higher than that in the control group (49.50％),the difference was statistically significant (x2=29.61,P＜0.05),and the observation group.The detection rate of stable plaque was 44.5 ％,which was significantly higher than that of the control group 22.5％,the difference was statistically significant (x2 =21.73,P＜0.05).Conclusion Hp infection can affect the level of lipid metabolism in patients,which is an important factor in the occurrence and development of atherosclerosis.
ABSTRACT
Objective To conduct bioinformatics analysis of children with severe malaria to find out the key gene changes in order to provide a new basis for the prevention and treatment of malignant malaria.Methods Microarray gene chip data was downloaded from public databases GEO and imported into the analysis software STRING,PANTHER and GenClip.The gene expression profiles,protein interaction networks,the process of molecular biology,gene function were analyzed.Results 623(1.93 ％) differentially expressed genes had a good diagnostic capabilities in the diagnosis of mild and severe malaria.OAS2,OAS3,IFIT3 and USP18 were the core sub-network node of the Protein-Protein Interactions.Differentially expressed genes mainly involved in the body's immune defense,immune response,response to external stimuli,the biological function of type 1 interferon activation pathways.Conclusion The progress of malaria of children may be in the regulation of OAS2,OAS3,IFIT3,USP18 and children's immune defense capacity decreased,the malaria began to progress more easily.
