ABSTRACT
AIM: To reveal that the targeted regulation of TGF-β1 by miR-21-5P is the key mechanism that mediates the activation of myocardial fibroblasts, and to clarify the intervention ofRadix Angelica Sinensis and Radix Hedysari ultrafiltration on the mechanism of miR-21-5P targeting to regulate TGF-β1 effect. METHODS: (1) The cells were randomly divided into normal group and irradiation group. The irradiation group received 6Gry single irradiation, and then RT-PCR was used to detect miR-21-5P, and Western Blot was used to detect the expression of α-SMA and TGF-β1. (2) The cells were randomly divided into normal group, irradiation group, miR-21-5P
