• Status: Unknown status

• Target enrollment: 0
• Participant gender: All

Summary

Thyroid carcinoma is the common endocrine system malignant neoplasm. At present it has become the malignant neoplasm of fastest growing incidence rate. More than 90% thyroid carcinoma is thyroid differentiated carcinoma（DTC）. Postoperative oral L-thyroxine suppressing thyroid stimulating hormone (TSH) treatment is the standard therapy in DTC patients. While TSH-suppressive therapy with L-thyroxine can cause subclinical hyperthyroidism in treatment of patients with thyroid differentiated carcinoma. The impact of this therapy on cognitive functions and mood have not been systematically studied. The investigators infer the subclinical hyperthyroidism caused by TSH-suppressive therapy may impact cognitive function and mood disorders in DTC patients. The aim of this study is to explore the possible mechanism of cognitive function impairment in the course of TSH-suppressive therapy by rat model of total thyroidectomy + TSH-suppressive therapy and clinical trials. The result of this study may provide clinical and experimental basis for the side effects risk result form TSH-suppressive therapy in DTC patients.
