Abstract: The present disclosure provides use of a long non-coding RNA (lncRNA) in preparation of a drug for controlling myocardial infarction, and belongs to the technical field of biomedicine. The present disclosure further provides use of a recombinant vector with a nucleic acid sequence of lncRNA CIR6 or a recombinant virus strain with the nucleic acid sequence of lncRNA CIR6 in inducing MSC differentiation into a cardiomyocytes in vitro, wherein the MSC is selected from the group consisting of a bone marrow-derived mesenchymal stem cell (BMSC) and an umbilical cord-derived mesenchymal stem cell (UCMSC). In the present disclosure, the lncRNA-CIR6 is derived from human heart. In vivo and in vitro experiments have shown that lncRNA-CIR6 induces the differentiation of the MSC into the cardiomyocyte; meanwhile, the cardiomyocyte detected by flow cytometry has an average transformation rate of not less than 90%.

Abstract: In a method for virtual reality (VR) interaction, a plurality of virtual objects in a VR environment is displayed. The plurality of virtual objects includes at least a first virtual object controlled by a first user and a second virtual object controlled by a second user. In response to an interaction initiated by the first virtual object towards the second virtual object, haptic feedback is triggered through a VR device worn by the second user. Apparatus and non-transitory computer-readable storage medium counterpart embodiments are also contemplated.
