Embodiment 1

[0029] Establishment of LPS-stimulated mouse peritoneal macrophage model:

[0030] 1.1 Materials

[0031] C57BL / 6 strain mouse, male, weighing 18-22g, purchased from Changzhou Cavens Experimental Animal Co., Ltd., production license number SCXK (Su) 2016-0010; LPS derived from Escherichia coli 0111:B4 was purchased from Sigma-Aldrich Company; RPMI-1640 medium, fetal bovine serum and double antibody are products of Gibco; CCK8 was purchased from Tongren Institute of Chemistry; TNFα Elisa detection kit was purchased from Invitrogen (Cat. No.: BMS607-3TEN); the microplate reader was BioTek brand.

[0032] 1.2 Isolation and culture of mouse peritoneal macrophages

[0033] C57BL / 6 mice were intraperitoneally injected with 3ml broth medium containing 3% mercaptosulfate (purchased from BD), and 3 days later, they were sacrificed by cervical dislocation and soaked twice in 75% alcohol for 1 minute each time. Then put the mouse on the aseptic operating table, slowly cut the abdominal...

Embodiment 2

[0041] Establishment of LPS-induced CSS mouse model:

[0042] 1.1 Materials

[0043] C57BL / 6 strain mouse, male, weighing 18-22g, purchased from Changzhou Cavens Experimental Animal Co., Ltd., production license number SCXK (Su) 2016-0010; LPS derived from Escherichia coli 0111:B4 was purchased from Sigma-Aldrich The company; the multifactor detection kit was purchased from BioLegend (Mouse Anti-Virus Panel, Cat No: 740622; Mouse Inflammation Panel, Cat No: 740446); the CytoFlex flow cytometer was a Beckman Coulter brand in the United States.

[0044] 1.2 Animal model

[0045] LPS was selected to induce CSS by intraperitoneal injection of 15 mg / kg into mice.

[0046] 1.3 Plasma separation

[0047] Four hours after LPS injection, blood was taken from the orbit to an anticoagulant tube containing EDTA. After standing still for 30 minutes, centrifuge at 4000rpm for 15 minutes at 4°C, and the supernatant, namely plasma, was transferred to an EP tube for later use.

Abstract

The invention discloses an application of paramivir in preparation of a medicine for treating a cytokine storm syndrome caused by infectious diseases. The infectious diseases are infections caused byviruses, chlamydia, mycoplasma, bacteria or parasites, the cytokine storm syndrome is the phenomenon that multiple cytokines in a body are rapidly produced in large quantities caused by infectious diseases, and the multiple cytokines in the body are TNFalpha, IL-6, IL-1beta, IL-12, IFNalpha and IFN-gamma. The invention proves for the first time that the paramivir has the effect of treating the cytokine storm syndrome caused by the infectious diseases, and can be used for preparing the therapeutic medicine used for the cytokine storm syndrome caused by the infectious diseases, and provides a novel anti-inflammatory solution for clinical treatment.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to the application of peramivir in the preparation of medicaments for treating inflammatory storms caused by infectious diseases. Background technique [0002] Infectious diseases refer to diseases caused by patients infected by various pathogens such as viruses, chlamydia, mycoplasma, bacteria or parasites. As the infection continues to intensify, the immune system produces a large amount of cytokines, and the pro-inflammatory cytokines can attract more immune cells to form a positive feedback loop, causing an "inflammatory storm", attacking the human body regardless of whether it is friend or foe. Damage to the immune system and vital organs such as the liver, kidneys, and heart. "Inflammatory storm", also known as cytokine storm syndrome (Cytokine storm syndrome, CSS), refers to the rapid development of various cytokines in body fluids such as TNFα, IL-1β, IL-6 and...
