The three-dimensional hierarchical differentiation and treatment view of qi

blood

and essence level reflects the evolution of diseases from organ dysfunction to tissue structure damage and even organ failure. This view can better explain the dynamic process of disease occurrence and progression and has practical guiding significance in the differentiation and treatment of internal medicine diseases. Interstitial lung disease is a clinically refractory disease

with the initial invasion to qi

followed by damage to ying blood

and then depletion of lung essence. Because the flow of qi is not smooth

it first affects lung qi. Then it leads to blood stasis and obstruction along the lung collateral. The depletion of essence destroys and penetrates the form and substance of the lungs. Interstitial lung disease

as a chronic progressive disease

has evolved from qi level syndrome characterized by organ dysfunction to essence level syndrome characterized by organic structural damage. The dynamic development of pathology and location of interstitial lung disease runs through the three-dimensional hierarchical differentiation and treatment view of qi

blood and essence level.The occurrence and development of interstitial lung disease are related to the depletion of qi

blood

and essence. This article explores the dynamic development of interstitial lung disease pathogenesis from a shallow to a deep perspective based on the three-dimensional hierarchical differentiation and treatment view of qi

blood

and essence level

providing new ideas and references for the differentiation and treatment of interstitial lung disease.
