Objective ， To investigate the role of serum chemokines and oxidative and antioxidant biomarkers in occupational （ silicosis） Methods silicosis hereinafter referred to as . A total of 58 patients with stage Ⅰ silicosis were selected as the - （ ）， research subjects using convenient sampling method. The serum levels of nuclear factor erythroid 2 related factor 2 Nrf2 -（ - ） - （ - - ） - heme oxygenase 1 HO 1 and 8 isoprstaglandin F2α 8 iso PGF2α were determined by enzyme linked immunesorbent assay. （ ） （ - ） The serum levels of lipid peroxide LPO and total antioxidant capacity TAOC were determined by chemistry colorimetric method. - - （ - ）， Luminex flow fluorescence technology was used to detect the serum levels of interferon γ inducible protein10 IP10 macrophage （ ）- ， - - （ ） inflammatory protein MIP 1α MIP1β and macrophagederived chemokine MDC . The above indicators were analyzed by factor Results - analysis. The information extraction rate of the original indicators of the nine biomarkers was 58.5%96.5%. Four common ， ， （ ） ， factors were extracted including Nrf2 antioxidant signaling pathway helper T cell Th 1 dominant chemotaxis the total ， ， ， ， ， oxidation/antioxidant balance and Th2 dominant chemotaxis whose variance contribution rates were 32.2% 19.1% 16.4% ， ， Conclusion - and 11.8% respectively and the cumulative variance contribution rate was 79.5%. Both the oxidant antioxidant ， disturbance and the dominance chemotaxis are involved in the occurrence and development of silicosis and the Nrf2 antioxidant signaling pathway plays the most critical role.
