The invention relates to the technical field of medicines, in particular to application of a methyl
flavonoid compound in preparation of a
medicine for preventing or treating acute
lung injury and / or
acute respiratory distress syndrome. The methyl
flavonoid compound provided by the invention has a structure as shown in the following formula: the methyl
flavonoid compound can obviously inhibit
inflammatory response, inhibit release of
inflammatory factors IL-1beta, IL-6, TNF-alpha and MPO, reduce the content of
inflammatory factors in
alveolar lavage fluid and serum of mice with acute
lung injury, and also can obviously inhibit
pulmonary edema, so that the methyl flavonoid compound can be used for treating acute
lung injury. The
traditional Chinese medicine composition disclosed by the invention can be used for reducing the generation of lung
effusion, reducing the
wet weight of the lung and inhibiting the rising degree of the ratio of
wet weight to
dry weight of the lung caused by acute
lung injury, so that the effects of resisting
inflammation and inhibiting lung
edema are achieved, the acute inflammatory injury of the lung can be effectively reduced,
respiratory distress is delayed or weakened, and the symptoms of severe and critical patients are relieved; the
