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.

Objective To compare the disadvantages and advantages of open thyroid surgery when using the harmonic scalpel (HS) vs conventional hemostasis (CH). MethodsOne hundred and fifty-one patients and 70 patients underwent thyroid surgery with HS or CH respectively. The tumor diameter, incisional length, the total operative time, thyroidectomy time, intraoperative bleeding volume, postoperative drainage volume and surgical complications were compared. The incisional length and the surgical complications in and after learning curve with harmonic scalpel were compared. ResultsThere was no significant difference between the HS and CH group at baseline. Incisional length, total operative time, thyroidectomy time, intraoperative bleeding volume and postoperative drainage volume in HS group were significantly lower than those of CH group (P0.05); the incisional length after learning curve was shorter than that in learning curve in HS group (P

Objective To assess the value and usage of real-time monitoring of the recurrent laryngeal nerve (RLN) during thyroid reoperation by RLN monitor. Methods One hundred and one patients were under general anesthesia and thyroidectomy. NIM-Response electromyographic (EMG) monitor system was used for assistant of dissection,exposure and protection of the RLN during the surgical procedures. Results There were 192 RLN were exposed during the surgeries in all 101 patients. The unilateral RLN injured in 10 patients was not specially explored the same side nerve. Among them 190 nerves were confirmed intact,the rest 2 nerves were resected because of tumor involving. Conclusion s NIM-Response electromyographic monitor system is sensitive and accurate for preserving the integrity of RLN during the thyroid reoperations. It is valuable for protecting RLN against iatrogenic injury. This system deserves general utilization for thyroid surgery,especially reoperation.

Objective To investigate the risk factors of hypoparathyroidism after total thyroidectomy and bilateral central lymph node dissection in patients with papillary thyroid carcinoma.Methods Data of patients with PTC who accepted total thyroidectomy and bilateral central lymph node dissection in the Department of Thyroid Surgery from Jan.2013 to Jun.2016 were collected and analyzed retrospectively.The patients were divided into normal group,transient hypoparathyroidism group and permanent hypoparathyroidism group according to the level of serum parathyroid hormone within 6 months after surgery.Clinical data were collected for comparison between the three groups.The risk factors of hypoparathyroidism were indentified with univariate analysis and multivariate analysis.Results A total of 468 patients,241 in the normal group and 227 in the hypoparathyroidism group (220 in the transient hypoparathyroidism group and 7 in the permanent hypoparathyroidism group),were included in the study.Univariate analysis showed that without application of carbon nanoparticles (P=0.04) and autotransplantation of more than one parathyroid gland (P＜0.001) were risk factors of hypoparathyroidism,and without application of carbon nanoparticles (P=0.047),incidental parathyroidectomy of one parathyroid gland (P=0.04),gross extrathyroidal extension (P=0.006) and c N1a were risk factors of permanent hypoparathyroidism.Multivariate analysis showed that without application of carbon nanoparticles (OR,0.437;95％ CI,0.243-0.789;P=0.006) and autotransplantation of more than one parathyroid gland (OR,3.025;95％ CI,1999-4579;,P=0.000) were independent risk fact ors of hypoparathyroidism,and without application of carbon nanoparticles (OR,0.197;95％ CI,0.039-0.982;P=0.048) and gross extrathyroidal extension (OR,12.381;95％ CI,1.432-107.036;P=0.022) were independent risk factors of permanent hypoparathyroidism.Conclusion When total thyroidectomy and bilateral central lymph nodes dissection were performed,carbon nanoparticles were routinely applied.Although autotransplantation of more than one parathyroid gland can increase the incidence of transient hypoparathyroidism,it can reduce the incidence of permanent hypoparathyroidism.If extrathyroidal extension is suspected,hypoparathyroidism should be emphasized to patient,and accurate operation should be done to reduce the incidence of hypoparathyroidism.

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.

Objective To explore the diagnostic value of needle stereotaction marking by steel wire(NSMSW) under mammography for nonpalpable early stage breast carcinoma (BC). Methods 29 patients with nonpalpable breast lesions were performed NSMSW under mammography,and the lesions were removed for biopsy to make the diagnosis. Results Nine patients(31.0%) were definited as early stage BC and twenty(69.0%) benign disease.The pathologic results in freezing sections and in parafin sections were the same. Conclusions NSMSW under mammography can resolve the problem of accurate location of nonpalpable breast lesions during operation .It is a credible, useful and practical method for diagnosis of nonpalpable early stage BC.

Hypoparathyroidism is one of the most common complications of thyroid surgery. Permanent hypoparathyroidism would bring great pain to patients, seriously affect the postoperative quality of life, is becoming the source of medical disputes. Parathyroid autotransplantation can effectively reduce the incidence of postoperative permanent hypoparathyroidism. However, there are still some dispute about the choice, including the time, the number, the method and the location of parathyroid autotransplantation, which need to be further researched. As a result, the program and survival rate of parathyroid autotransplantation will be optimized and improved, respectively.

OBJECTIVE: To examine the psychometric features of the body image after breast cancer questionnaire-Chinese version (BIBCQ-C) in Chinese women with breast cancer. METHODS: A total of 545 women with breast cancer received a demographics investigation: BIBCQ-C and hospital anxiety and depression scale (HAD). Four weeks later, 31 patients were selected randomly to finish BIBCQ-C again. RESULTS: The Cronbach's alpha coefficient for the total scale was 0.90, and that for the 6 factors ranged from 0.62 to 0.87. The mean inter-item correlation coefficient of the total scale was 0.16, and the mean inter-item correlation coefficient of the subscales ranged from 0.21 to 0.57, and the test-retest reliability of the total scale and 6 factors was over 0.60. The confirmatory factor analyses supported the 6-factor model, and BIBCQ-C were significantly correlated with the symptom scales of anxiety and depression (r=0.20, 0.21, P<0.01). CONCLUSION BIBCQ-C is reliable and valid, which can effectively assess body image of Chinese women with breast cancer.
