Abstract:
Objective To investigate the expressions of inflammatory factors in papillary thyroid carcinoma tissue and their relationships with the clinical pathological characteristics,and to provide an experimental basis for guiding clinical treatment and prognosis.Methods 74 patients with papillary thyroid carcinoma dignosed by puncture were selected as experimental group,and 26 cases of healthy people were used as normal control group.The fasting venous blood samples from the subjects in two groups were collected,and the postoperative specimens from cancer tissue,adjacent normal tissue and the fasting venous blood 7 d after operation of the patients in experimental group were collected again.The interleukin 1α(IL-1α),interleukin 1β(IL-1β)and cyclooxygenase-2 (COX-2)protein expression levels in serum,cancer adjacent normal tissue and cancer tissue were detected by ELISA;the gene and protein expression levels of IL-1α,IL-1βand COX-2 were examined by real-time fluorescent quantitative method and immunohistochemistry;the relationships between their expressions and clinical stages, pathological types,lymph node metastasis of thyroid papillary carcinoma were analyzed.Results The expression levels of serum IL-1α,IL-1βand COX-2 protein of the patients in experimental group were significantly higher than those in normal control group (P<0.01);the gene and protein expression levels of IL-1α,IL-1βand COX-2 in thyroid papillary carcinoma tissue were significantly higher than those in adjacent tissue (P<0.01).There were positive correlations between the expressions of IL-1αand IL-1β,IL-1αand COX-2,IL-1βand COX-2 in thyroid papillary carcinoma tissue (r=0.64,P=0.035;r=0.71,P=0.042;r=0.69,P=0.038).Conclusion The expression levels of IL-1α, IL-1βand COX-2 in thyroid papillary carcinoma tissue are increased, suggesting that inflammation is involved in metastasis and invasion of thyroid papillary carcinoma,its application is expected to become a new means of cancer treatment strategies.
