Abstract: The invention “use of biomarker or biomarkers combination in preparing a diagnostic reagent for fulminant myocarditis and a drug for fulminant myocarditis” belongs to the field of disease diagnostic reagents and drugs. The biomarker comprises Siglec-5. The biomarkers combination is further selected from the group consisting of sST2, PAI-1, Siglec-5, CD163, CD40, P-Cadherin, CD14, CTLA4. The invention finds that the levels of the biomarker in plasma of patients with fulminant myocarditis is increased, and proves that the biomarker plays a role in diagnosing fulminant myocarditis and a role as a drug target in relieving and/or improving fulminant myocarditis. The level of the biomarker can be detected to forecast or auxiliary diagnose fulminant myocarditis or estimate prognosis of fulminant myocarditis. Meanwhile, level of the biomarkers is controlled through drugs, more intensified diagnosis and follow-up treatment can be carried out on diseases, and the biomarkers have huge clinical application value.

Abstract: An optical power compensation method and a device relating to the communications field comprises: a first node that obtains a first optical power and a first timepoint, receives at least two second optical powers sent by a second node, obtains second timepoints corresponding with the at least two second optical powers, where the second timepoint is a timepoint at which the first node receives the second optical power, and determines a target timepoint from the second timepoints according to a preset delay and the first timepoint. The first node determines a variation of a span loss according to a target optical power and the first optical power, where the target optical power is a second optical power corresponding to the target timepoint, and adjusts a gain value and/or an attenuation value of the first node according to the variation of the span loss.
