Abstract Objective To investigate the expression and significance of thyrotropic-stimulating hormore receptor (TSHR), thyroid transcription factor-1 (TTF-1), paired box gene-8 (Pax-8) in papillary thyroid carcinoma (PTC), Hashimoto′s disease (HT) with PTC, nodular goiter (NG) and normal thyroid tissues. Methods From September 2018 to June 2019, thyroid tissues confirmed in the Endocrine Department of our hospital and operated in the Thyroid Surgery were collected, including 16 cases of simple PTC, 24 cases of HT combined with PTC, 32 cases of nodular goiter and 40 cases of normal thyroid tissues adjacent to the carcinoma. The thyroid tissues obtained during the operation were treated with dehydration, transparency and embedding. Immunohistochemical staining of TSHR, TTF-1 and Pax-8 was performed, and the staining results were observed under the microscope.The Chi-square test was used to compare the intergroup rates, and when the difference was statistically significant, Chisquare partition was used to make pairwise comparison. Results 1) There were significant difference about the strong positive expression of TSHR and TTF-1 among four groups of thyroid tissue (P＜0.001,P=0.004), while no significant difference in the strong expression of Pax-8 were found among four groups of thyroid tissue (P=0.642). 2) After adjusting the statistical examination level α′=0.008, pairwise comparison showed that the strong positive expression of TSHR in PTC group was lower than that in NG and normal thyroid tissue(P＜0.001, P=0.002);the strong positive expression of TSHR in HT combined with PTC group was lower than that in NG (P=0.001); while the strong positive expression of TTF-1 in HT combined with PTC group was lower than that in NG (P=0.002).However,there was no significant difference of the strong positive expression of TSHR, TTF-1 in other groups respectively (P>0.008). 3)The positive expression of TSHR,TTF-1 were not related to age, tumor diameter and lymph node metastasis. However, the positive expression of Pax-8 inpatients with lymph node metastasis was lower than that without lymph node metastasis (P=0.030), and the expression of Pax-8 was not related to gender, age, and tumor diameter. Conclusion The strong positive expression of TSHR and TTF-1 in PTC group was lower than that in NG and paracancerous normal thyroid tissues. There was no difference in the expression of Pax8 in different types of thyroid tissues. The lower expression of Pax-8 in PTC tissues might result in lymph node metastasis.
