ABSTRACT
Objective:To explore the effect of Angelica Sinensis Volatile Oil on the mi RNA expression profiling in myocardium tissue of the spontaneously hypertensive rats (SHRs),and to clarify the possible mechanism of Angelica Sinensis Volatile Oil.Methods:All the SHRs were divided into Angelica group,model group and captopril group,and other Wistar rats with the same age were selected as control group.The non-invasive systolic blood pressure was detected;after 4 weeks of administration,the changes of miRNA expression profiling in myocardium tissue were measured by Affymetrix miRNA 4.0 Array.KEGG analysis was used to identify the target genes. Results:Compared with control group,the systolic blood pressure of the rats in model group was significantly decreased (P < 0.05)before treatment.4 weeks after administration,compared with model group,the systolic blood pressure of the rats in Angelica group was significantly decreased (P <0.05).Compared with model group, 29 differential miRNAs of rats in Angelica group were found (P < 0.05 ), with 13 up-regulated miRNAs and 16 down-regulated miRNAs.The KEGG analysis results showed that miR-19a,let-7i,and miR-181c were related to insulin signaling pathways; let-7i, miR-181a, and miR-455 were related to VEGF signaling pathways;miR-122,miR-181a, miR-200b, miR-181c, let-7i, and miR-19a were related to apoptosis (P < 0.05 ). Conclusion:Angelica Sinensis Volatile Oil can decrease the blood pressure in SHRs and it can regulate the blood pressure by regulating the miRNA related to insulin signaling pathways and VEGF signaling pathways.
ABSTRACT
Objective To understand the status of Clonorchis sinensis infection and its risk factors in Futian District Shen?zhen City so as to provide the evidence for formulating the strategy of prevention and control. Methods Two monitoring points were randomly selected and the permanent population aged≥3 years were investigated and their stool samples were detected for the eggs of C. sinensis by using Kato?Katz technique. Meanwhile the risk factors of infection were also investigated. Results A total of 743 subjects were examined and 7 persons were infected with C. sinensis and the infection rate was 0.94%. Most of the infected cases were focused on 20?40 and 40?60 age groups. The risk factors were eating raw or semi?cooked fish and the protec?tive factor was the use of separated cutting board for cooked or uncooked food. Conclusion The infection rate of C. sinensis is low in the population of Futian District. However the health education especially for diet health education still should be strengthened.
