Abstract: Use of inosine in preparing a drug for the treatment of coronavirus disease 2019 (COVID-19), where a formulation of the drug includes one or more selected from the group consisting of tablets, capsules, oral liquid preparations, emulsions, and injections. Inosine can reduce level of severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) induced interleukin-6 (IL-6), alleviate SARS-COV-2 caused inflammatory lung injury, and further increase the percent survival of critically ill patients with SARS-COV-2.

Abstract: The present disclosure provides an inspection system for contact network damage detection, including: a laser imaging radar, an X-ray transmitter, a booster, an X-ray receiver, and a control circuit board. The laser imaging radar emits a laser beam to a contact line for scanning. A laser radiation reflected by the contact line is received, and a continuous analog signal is generated, which is restored to a real-time image of the contact line. After the analog signal is converted into a digital signal on the control circuit board, a height of the contact line in a horizontal direction is calculated to determine a wear degree on an outer surface of the contact line. The booster boosts electric energy obtained by the pantograph on the contact line and supply power to the X-ray transmitter.
