Embodiment 1

[0021] Preparation of the drug:

[0022] Mix 20.5 mg of carbon monoxide releasing molecules with 1 ml of DMSO to obtain a preparation A with a concentration of 40 mM, and use it at a dose of 8 mg / kg body weight; mix and dilute 20,000 IU / 2 ml of heparin with normal saline 10 times to obtain 1,000 IU / L Heparin solution preparation B is used at a dose of 100 IU / kg body weight.

Embodiment 2

[0024] Effects of CORM-2+ultramicrodose heparin on WBC, PLT count, plasminogen (PLG) and antithrombin III (AT-III) activity in septic mice.

[0025] experiment method:

[0026] (1) Animal and CLP sepsis model

[0027] Male C57BL / 6 mice, 6-8 weeks old, weighing 18±2 grams, were raised in a general laboratory (commercial dry block feed, free access to water). The experimental animals were divided into three groups according to the random number table method: Sham group (n=9), CLP group (n=9) and CLP+CORM-2+heparin group (n=9).

[0028] Under isoflurane inhalation anesthesia, the mice in the CLP group were subjected to cecal ligation and perforation, and 1.5ml of normal saline was injected intraperitoneally after injury to resist shock; the mice in the CLP+CORM-2+heparin group were injected with CORM-2 (8mg / kg), and at the same time intraperitoneally inject heparin 100U / kg body weight.

[0050] Effects of CORM-2+ultramicrodose heparin on coagulation system and platelet aggregation in septic mice

[0051] experiment method:

[0052] (1) Animal and CLP sepsis model

[0053] Male C57BL / 6 mice, 6-8 weeks old, weighing 18±2 grams, were raised in a general laboratory (commercial dry block feed, free access to water). The experimental animals were divided into three groups according to the random number table method: Sham group (n=9), CLP group (n=9) and CLP+CORM-2+heparin group (n=9). Under isoflurane inhalation anesthesia, the mice in the CLP group were subjected to cecal ligation and perforation, and 1.5ml of normal saline was injected intraperitoneally after injury to resist shock; the mice in the CLP+CORM-2+heparin group were injected with CORM-2 (8mg / kg), and at the same time intraperitoneally inject heparin 100U / kg body weight. All animals were sacrificed with isoflurane inhalation 24 hours after injury and collected specimens.

Abstract

The invention provides application of carbon monoxide-releasing molecules and heparin in preparing a medicament for treating sepsis. The carbon monoxide-releasing molecules are combined with the ultramicro heparin to improve the coagulation defects of the sepsis, the control of the concentration of the carbon monoxide-releasing molecules and the heparin is relatively easy and correct, the carbon monoxide-releasing molecules and the heparin can be conveniently added when used for a long time, simultaneously the consumption and side effect of the heparin are reduced, and the carbon monoxide-releasing molecules and the heparin can meet the requirement of clinical application. The carbon monoxide-releasing molecules are combined with the ultramicro heparin to improve the coagulation defects ofthe sepsis, the control of the concentration of the carbon monoxide-releasing molecules and the heparin is relatively easy and correct, the carbon monoxide-releasing molecules and the heparin can beconveniently added when used for a long time, and the carbon monoxide-releasing molecules and the heparin can meet the requirement of clinical application.

Description

technical field [0001] The present invention relates to the new application of carbon monoxide releasing molecule and heparin, specifically, relates to a carbon monoxide releasing molecule combined with ultra-micro dose heparin, which can be used early to treat blood coagulation dysfunction in sepsis. Background technique [0002] Sepsis is a common complication after severe trauma, shock and infection. Further development can lead to septic shock and multiple organ dysfunction syndrome (MODS). Clinical treatment still has little effect, and the mortality rate remains high. Studies have shown that vital organ failure after severe sepsis, especially multiple organ failure, has a high mortality rate. Once multiple organ failure occurs, existing treatment measures are difficult to reverse it, so it is particularly important to prevent or reduce early organ damage in sepsis. The coagulation function changes in the early stage after sepsis, and the degree of systemic inflammato...
