Abstract: - Well characteristic biomarkers are helpful for understanding the disease condition of patients with occupational pneumoconiosisand predictthediseaseevolution.Currently,related biomarkersarewidelystudied and theyinclude:epithelial cell injury related biomarkers such as salivary glycochain antigen, Clara cell protein and surfactant protein; inflammatory - - response related biomarkers such as interleukin, tumor necrosis factor α, chemokine, high mobility group protein 1 and - - L selectin; oxidative stress related biomarkers such as superoxide dismutase, glutathione, malondialdehyde, heme oxygenase 1 and lactate dehydrogenase; pulmonary fibrosis related biomarkers such as matrix metalloproteinases and transforming growth - - - - - factor β; non coding RNA such as miR 19a, miR 29 and miR 146a, et al. These biomarkers are helpful to understand the pathogenesisofoccupationalpneumoconiosisandguidethediagnosis,treatmentandprognosis.However,moreresearchneedsto-bedoneontherepeatabilitytestofbiomarkers,combinedapplicationandtheminingofnoncodingRNAastargetsfordisease diagnosisandtreatment.
