RESUMO
Objective: To investigate the expressions of Fas, FasL in papillary adenocarcinoma of thyroid gland tissues and their tumor infiltrating lymphocytes(TIL), and its relationship with apoptosis and Fas, FasL in thyroid tumors.Methods: We detected the apoptotic rate and the expression of apoptotic related gene Fas in 43 cases of papliiary adenocarcinoma of thyroid gland with flow cytometry. The expression Fas and FasL were measured in 43 cases of papillary adenocarcinoma of thyroid gland, 28 cases of thyroid adenoma,43 paplillary adenocarcinoma of thyroid gland TIL,17 thyroid adenoma TIL using flow cytometry.Results: 19 cases in papillary adenocarcinoma showed low expression of Fas protein with an average apoptotic rate of 3.71% and 24 cases had high expression of Fas with an apoptotic rate of 7 26%(P
