Objective To investigate the clinical significance of the three iodide transporters in thyroid diseases. Methods Literatures about the Na+/I-symporter (NIS), pendrin and human apical iodide transporter (hAIT) in recent years were reviewed and their expressions in different thyroid diseases were also analyzed. Results NIS proteins express at the basolateral membrane of thyrocytes in normal thyroid tissue, while pendrin and hAIT proteins are limited to the apical membrane of thyrocytes lining in the follicular lumen. In the tissues of thyroid carcinomas, it was found that the NIS proteins expressed in the cytoplasm and their expressions decreased; The mutation of NIS gene may be one of the main causes of congenital hypothyroidism. The expression of prendrin protein may be related to the function of follicles: its expression level increased significantly both in Graves diseases and toxic adenomas, but significantly decreased in differentiated thyroid carcinoma. However, the correlation between the decrease and the degrees of differentiation of carcinoma cell line are still disputable. The expression of hAIT protein does not significantly altered in hyperfunctioning tissues. It only slightly decreased occasionally in hypofunctioning adenomas, but it decreased significantly in thyroid carcinomas. Conclusion The abnormal expressions of the three iodide transporters may be related closely with the type of thyroid diseases. However, their pathogenic mechanisms and the causes of their abnormal expression are still unknown, which need to be studied further.

Enthusiasm is an intrinsic motive that drives the ethical and moral aspects of nursing practice.Love is the source of enthusiasm.An enthusiastic nurse loves life,work and patients.Loving patients is essential to inflame passion for patient care.A desire for and pursuits of benevolence is the key to enthusiasm.Only the element of benevolence integrated into enthusiasm can nurses arouse a sense of compassion,responsibility and honour,which is then advanced to the realm of humanitarian-Heal the Wounded,Rescue the Dying.The essence of enthusiasm is sincerity,that is,providing patients wholehearted care rather than hypocritical act.Caring for patients is based on goodwill and altruism.Enthusiasm is also the driving force for nurses' creativity.It inspires a positive life,pushes to pursue self-actualization and propels continuous creation.

Objective To study the clinical value of Na+/I-symporter(NIS)expression on thyroid carcinoma diagnosis and 131I therapeutic effects prediction.Methods Thirty-one cases of thyroid carcinomas enrolled in this hospital from 1998 to 2006 were included.Using immunohistochemical method,NIS expression location,positive cell staining and expression intensity were observed,which was calculated by immunohistochemical scores(IHS)and NIS expression level was compared between primary and metastatic carcinoma.Results NIS was over-expressed on the basolateral membrane in positive control——Grave disease tissue,and showed no staining in negative control.NIS was expressed in cytoplasm in all 31 primary carcinomas,and IHS was over or equaled to 4 in 80.65% of them.Except for 2 no staining,NIS was expressed in cytoplasm in the rest 28 metastatic carcinomas.NIS expression was related to the pathological type of thyroid carcinoma,the strongest in PTC,then FTC,and the weakest in fvPTC.NIS expression in metastatic carcinoma was related to that in primary carcinoma.Conclusion NIS is over-expressed in cytoplasm in most thyroid carcinoma,and the iodide uptaking defect is mainly due to its wrong location.It has great potential to be applied in clinic by that it can help with the differential diagnosis of benign and malignant thyroid diseases,especially between FTA and FTC,and that it can help predict the therapeutic effects of 131I therapy following thyroid operation.
