Objective; The aim of this study was to investigate the effects of radiofrequency treatment on sodium/iodide symporter expression of thyroid cancer ceils. Methods： In 29 thyroid cancer patients with low or no expression of soda ／ iodide symporter, the radio frequency combined 1311 therapy was used, the whole-body scintigraphy and serum Ig were detected before and after the radiofrequency treatment. Results： The whole-body scintigraphy showed that 4 cases （4/29） before radiofrequenc_y treatment had positive iodine uptake, 19 cases （19/29） two weeks after radiofrequency treatment had the positive iodine uptake, 12 cases （12/29） four weeks after radiofrequency treatment had the positive iodine uptake. Four weeks after radiofrequency treatment, 5 cases had increased serum Ig levels, 17 cases had decreased serum Ig levels, 7 cases showed no change. 25 cases （25/29） were effective, 15 cases （15/29） were cured. Conclusion： The radiofrequency induced the non-expressed the sodium/iodide symporter of thyroid cancer cells regain the iodine intake ability, it improved the clinical efficacy of 131I therapy in dedifferentiated thyroid cancer.

Objective To observe the clinical inhibition of circulating tumor cells(CTCs) in differentiated thyroid carcinoma(DTC) by the extract of scabrous patrinia root(Huikangling).Methods Eighty-seven DTC patients tested positive for CTCs were randomly divided into two groups; all patients were treated with oral levothyroxine sodium in accordance with the DTC endocrine inhibition treatment criteria. Patients(n = 45) in the treatment group were provided the standard endocrine therapy along with oral Huikangling(0.4 g/tablet, 0.4 g × 3/time, 3 times/day, 12 weeks). Patients(n = 42) in the control group were only provided the standard therapy. After 4 and 12 weeks, CTCs in the blood were detected by flow *** After 4 weeks of oral Huikangling treatment, CTCs were detected in 18(40%) and 29(69%) patients in the treatment and control groups, respectively; the difference was statistically significant(χ2 = 8.49, P nificant(χ2 = 5.68, P nisms.

We aimed to detect cytokeratin 19 （CK19） and polymorphic epithelial mucin 1 （MUC1） expression in peripheral blood of thyroid cancer patients, and investigate the clinical value of it as a diagnostic marker for circulating blood micrometastases. Methods： The flow cytometry （FCM） was used to detect and analyze CK19 and MUC1-expressing cells in peripheral blood of 491 thyroid cancer patients. Results： CK19 and MUC1 expression showed no statistically significant difference with gender and age in thyroid cancer patients （P 〉 0.05）, while had statistically significant difference with tumor size, lymph node stage and distant metastasis （P 〈 0.01）. The expression of CK19 and MUC1 were positively correlated （r = 0.628, P = 0.00）. Conclusion： CK19 is closely related to MUC1 expression, tumor size, extent of invasion and distant metastasis in peripheral blood of thyroid cancer patients. The circulating blood CK19 and MUC1 tests can help predict thyroid cancer micrometastases and prognosis.

Objective： The purpose of the study was to investigate the effects of parathyroid hormone and parathyroid hormone receptor monoclonal antibody on in vitro growth and proliferation of human medullary thyroid carcinoma cell lines. Methods： The medullary thyroid carcinoma cell line was cultured in vitro, with parathyroid hormone and parathyroid hormone receptor monoclonal antibody treatment intervention, the growth of the cells was observed under an inverted contrast micro scope, the MTT assay was used to detect the cell growth inhibition rate. Results： Under the inverted contrast microscope, the cells changed significantly, the parathyroid hormone and parathyroid hormone receptor monoclonal antibodies can effectively inhibit the proliferation of medullary thyroid cancer cells in a time and dose dependent. When parathyroid hormone concentra tion reached a concentration of 2.0 IJmol/L, the parathyroid hormone receptor monoclonal antibody reached a concentration of 1.0 μmol/L, the cell growth was most significantly inhibited （P 〈 0.05）. Conclusion： Parathyroid hormone and parathyroid hormone receptor monoclonal antibody were able to inhibit the proliferation of medullary thyroid carcinoma cells and signifi cantly reduce the proliferation index.

Objective The aim of this study was to investigate the effects of rearranged during transfection(RET)mutation on the expressions of calcitonin(CTn)and procalcitonin(PCT)in sporadic medullary thyroid carcinoma(SMTC).Methods RET mutation was detected by polymerase chain reaction direct sequencing in 64 cases of SMTC,and the expression levels of CTn and PCT in SMTC tissues were detected using the immunohistochemical streptavidin-perosidase(SP)*** effect of RET mutations on the expression of CTn and PCT along with its relationship with clinicopathological parameters were *** The expression rates of CTn and PCT in SMTC tissues were 90.6%(58/64)and 67.2%(43/64),*** and PCT expression were found to be associated with tumor size and lymph node metastasis(P0.05).There was a significant correlation between CTn and PCT expression(r=0.269,P=0.041),and the intensity of positive CTn expression was positively correlated with RET mutation(r=0.507,P=0.000).However,PCT expression was not associated with RET mutation(r=0.188,P=0.136).Conclusion High expression of CTn and PCT was associated with the progression of medullary carcinoma,and the intensity of CTn expression was associated with RET *** may provide valuable information for the diagnosis and prognosis of SMTC.
