Thyroid tissue and metastatic lymph nodes of tissue results difference (P > 0.05), and other organizations results than there were significant differences (P < 0.05);Had metastatic lymph nodes and other non-thyroid tissue results have significant differences (P < 0.05), results are obvious different positive group and negative control group (P < 0.05).( Table5.The coincidence rate with pathological results)
