Methods： By using ELISA method, we detected the serum levels of MBL and MASP-2 in 26 patients with papillary thyroid carcinoma （PTC）, 30 patients with thyroid adenoma （TA） and 26 healthy people, respectively. Results： Serum MBL level was （565.23 ± 76.70） μg/L in PTCs higher than （324.267 ±24.74） μg/L in TAs, and （152.69± 16.95） IJg/L in healthy of controlling group. There was statistical significance between PTC and TA （P 〈 0.05）, however there was no difference between TA and healthy （P 〉 0.05）. Serum MASP-2 level was （726.153± 78.88） pg/L in PTCs higher than （379.266 ± 30.26） μg/L in TAs, and （203.846 ± 29.09） μg/L in healthy. Serum MASP-2 level was higher in PTCs than TAs, and the difference had statistical significance （P 〈 0.01）. But no difference was observed between in TAs and healthy. Conclusion： These findings might reflect inflammatory processes induced by defense mechanisms, in response to the development of the turnout. MBL may also be involved in the elimination of possible tumourigenic pathogens.展开更多
