ABSTRACT
OBJECTIVE: To explore the changes of serum levels and significance of surfactant protein( SP) A and SP-D in patients with stage Ⅰ coal workers' pneumoconiosis( CWP). METHODS: A random sampling method was used to select 88 cases of stage Ⅰ CWP patients as the CWP group,50 cases of healthy underground miners with similar dust exposure history as the dust exposure group and 38 cases of ground workers without dust exposure history as the control group. The serum levels of SP-A and SP-D in 3 groups were detected by enzyme-linked immunosorbent assays. RESULTS: The levels of serum SP-A and SP-D in the CWP group and the dust exposure group were higher than that of the control group( P <0. 05). The serum level of SP-D in the CWP group was higher than that of the dust exposure group( P < 0. 01). The serum level of SP-D in the smoking CWP subgroup was lower than that of the non-smoking CWP subgroup( P < 0. 05).CONCLUSION: The abnormal serum levels of SP-A and SP-D were related to the development of stage Ⅰ CWP. Smoking might affect the serum level of SP-D in stage Ⅰ CWP patients.
