Problems solved by technology

[0003] At present, the treatment plan for ALI is generally recognized at home and abroad: (1) remove the cause; (2) on the basis of active treatment of the primary disease, mechanical ventilation (Mechanical ventilation, MV) should be used as soon as possible to correct hypoxia and improve tissue oxygen supply; MV is ALI One of the classic treatment methods can correct refractory hypoxia, prevent alveolar collapse, resist pulmonary edema, improve gas exchange, reduce spontaneous breathing work, and prevent respiratory muscle fatigue, but it can only maintain the body's physiol

Embodiment Construction

[0039] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0040] 1. Experimental drugs and reagents

[0041] Preparation of Dayuan Drinking Water Extract: Dayuan Drink with the formula of 142.5g betel nut, 71.5g Magnolia officinalis, 71.5g Zhimu, 35.74g Caoguo, 35.75g licorice, 71.5g white peony and 71.5g Scutellaria baicalensis was placed in water and refluxed Twice, 2 hours each time, take the extract respectively, combine the two extracts, and concentrate the extract to obtain the original drinking water extract (DYY-H 2 O) 116.8 g.

[0042] The preparation of the supernatant of Dayuan drinking water extraction and precipitation: Dayuan drink with the formula of 570g betel nut, 286g magnolia bark, 286g Zhimu, 143g Tsaoguo, 1...

Abstract

The invention provides application of a membrane-source-opening beverage in preparation of an acute lung injury resisting medicine. The membrane-source-opening beverage is utilized for preparing the acute lung injury resisting medicine. The method comprises the steps that the membrane-source-opening beverage is placed in water for backflow, and an extracting solution is obtained and concentrated to obtain a membrane-source-opening beverage aqueous extract or a total extract; after ethyl alcohol is added into the total extract, standing and suction filtration are performed, the obtained filtrate is concentrated to obtain supernate of membrane-source-opening beverage water extracting alcohol precipitation. By means of the membrane-source-opening beverage, symptoms of pulmonary edema in mice can be relieved, the content of nitric oxide and protein in bronchoalveolar lavage fluid is lowered, the content of the tumor necrosis factors -alpha (TNF-alpha), interleukin-6(IL-6) and interleukin-1beta(IL-1beta) is lowered, the complement C3, C3c, C5a level in blood serum is lowered, the protective effect is achieved on the lung tissue, lung cells and blood capillaries of mice, and the complement precipitation in the lung tissue is relieved.

Description

technical field [0001] The invention relates to the application of Dayuan decoction in the preparation of anti-acute lung injury medicine. Background technique [0002] Acute lung injury (acutelunginjury, ALI) is based on diffuse lung cell injury, pulmonary edema and pulmonary inflammatory cell infiltration caused by pulmonary vascular injury are its pathological features, and the main clinical manifestations are severe hypoxemia, diffuse Acute respiratory distress syndrome (ARDS) will eventually develop in some patients, causing irreversible acute respiratory failure and multiple organ dysfunction, with a mortality rate as high as 30-40%; the pathogenesis of ALI is complex The risk factors for ALI can be direct damage from the lungs, or indirect damage to the lungs from extrapulmonary factors through systemic inflammatory responses (see: BaffertF, LeT, ThurstonG, et al.Angiopoietin-1decreasesplasmaleakagebyreducingnumberandsizeofendothelialgapsinvenules. 290(1):H107-H118;W...
