Objective: To conduct high throughput detection of microRNA expression in patients with non-ST segment elevation myocardial infarction (NSTEMI) before and after drug intervention
compare the expression changes of microRNA before and after treatment with Chinese and western medicines
and analyze the intervention targets and mechanism of Chinese medicines for promoting blood flow and eliminating blood stasis. Method: Patients who met the diagnostic criteria of Western medicine diseases and the diagnostic criteria of traditional Chinese medicine (TCM) syndromes were divided into NSTEMI Chinese medicine treatment group and NSTEMI western medicine control group
35 cases in each group. Their peripheral blood was extracted
peripheral blood mononuclear cells (PBMC) were isolated and total RNA was extracted. The active microRNA and its target genes in each group were identified according to differentially expressed microRNAs
gene pathways and network analysis results. Result: In the microRNA expression profile
there were differences between Chinese medicine treatment group before and after treatment as well as between TCM treatment group and western medicine control group after treatment
hsa-miR-92a
hsa-miR-363
hsa-miR-499
hsa-miR-30b
hsa-miR-454-3p
and hsa-miR-933 expression levels were down-regulated
while hsa-miR-144
hsa-miR-451
hsa-miR-494
and hsa-miR-320 expression levels were up-regulated in TCM treatment group after treatment. These 10 microRNAs were considered as the intervention targets of salvianolate for NSTEMI. Real-time PCR
results verified that as compared with the western medicine control group
hsa-miR-92a
hsa-miR-30b
hsa-miR-499 and hsa-miR-454 expression levels were down-regulated while the expression of hsa-miR-494 was up-regulated after treatment in Chinese medicine treatment group (P<0.05). Conclusion: There are differences in the expression profiles of microRNAs between the Chinese medicine treatment group and the western medicine control group before and after the treatment of NSTEMI
and the screened miRNAs may be the intervention targets for Chinese medicines of promoting blood flow and eliminating blood stasis.
