Abstract: The present invention provides a use of a phillyrin/phillygenin composition which targets and inhibits 3CLpro protein of COVID-19 virus, in preparation of an anti-coronavirus drug or a drug for treating a disease caused by the coronavirus, wherein the coronavirus is COVID-19 virus, and the disease caused by the coronavirus is COVID-19.

Abstract: The invention discloses a mechanical performance testing device and a hydraulic control system thereof. The instrument comprises a base, a fixing means, a first testing means and a second testing means. Wherein the base is connected with the fixing means, each of the first testing means and the second testing means is configured to cause the fixing means to move in various directions. And the instrument can simultaneously apply multiple forces and torques on the element, such that the different stiffness characteristics of the element can be tested simultaneously. The hydraulic control system comprises fuel tank, oil pump and control valves. And the fuel tank, the oil pump and the control valves connect successively. The mechanical performance testing device with hydraulic control system can improve efficiency of the test, reduce the working intensity of inspector, increase the security in detection process, and improve the accuracy of measurement results.
