Abstract: The present invention of use of lncRNA DCRT as drug and its drug for treating cardiovascular diseases, screening method, and preparation method thereof belongs to the field of biomedicine. The present invention provides use of lncRNA DCRT with sequence shown as SEQ ID NO. 1 as drug. The present invention further provides a new drug for treating cardiovascular diseases with lncRNA DCRT as target. Based on lncRNA DCRT, the present invention also provides a screening method and preparation method of drug for treating dilated cardiomyopathy. The present invention confirms through animal experiments that upregulation of lncRNA DCRT has effect of improving central function impairment and pathological increase in myocardial cell area in a cardiac dilation model induced by thoracic aortic constriction surgery.

Abstract: A setting and coordination calculation method for protection setting value of DC system is introduced. A protective template library is built by classifying the DC system protections to various protective areas and classifying each protective area. Based on project configuration, a mathematical model of converter station is built, the parameters of equipment components and locations of short circuit are given. The short-circuit current value and the parameters of equipment component are regarded as process parameters during the setting and coordination. The electromagnetic transient simulation is carried out at first in this method. And a specified and standard project of the setting and coordination is formed by abstracting and standardizing the process of the setting and coordination, which makes present setting and coordination of DC transmission engineering independent of the electromagnetic transient simulation software.
