Objective To evaluate the clinical value of lymph node micrometastases in central group(Ⅵ) lymph node in follicular carcinoma of thyroid.Methods Three hundred and twenty-six negative neck lymph nodes in 68 cases on routine pathological examination(pN0) were examined by keratin-19 monoclonal antibody and S-P immunohistochemistry to detect expression of keratin-19 to confirm lymph node micrometastasis in each neck lymph node,and compare the pathological type and follow-up data of all cases.ResultsThere were 46 neck lymph nodes showed positive lymph node micrometastasis among 326 negative neck lymph nodes that included 4 lymph nodes in group Ⅱ(4/42),5 lymph nodes in group Ⅲ(5/34),5 lymph nodes in group Ⅳ(5/49),1 lymph node in groupⅤ(1/17) and 31 lymph nodes in group Ⅵ(31/184).6 in 14 cases with positive lymph node micrometastases showed distant metastasis or local recurrence,but only 3 in 54 cases with negative lymph node that micrometastases distant metastasis or local recurrence(P

Objective To investigate the effect of radiofrequency on sodium/iodide symporter expression in thyroid cancer cell. Methods 29 thyroid cancer patients with low or no expression of sodium/iodide symporter underwent radiofrequency ablation combining 131I radiotherapy. Whole-body nuclide imaging and serum Ig were examined before and after radiofrequency ablation. Results Whole-body nuclide imaging showed that there were 4 cases (4/29) positive before radiofrequency ablation, 19 cases (19/29) positive two weeks after radiofrequency ablation and 12 cases (12/29) positive four weeks after radiofrequency ablation. Four weeks after radiofrequency ablation, 4 cases showed an increased serum Ig level, 17 cases with a decreased serum Ig level and 17 cases without any change in serum Ig level. The total effective cases were 25 (25/29) and 15 cases (15/29) were completely cured. Conclusion Radiofrequency ablation induces thyroid cancer cells without sodium/iodide symporter expression to resume iodine intake and thus increased clinical effect of 131I on undifferentiated thyroid cancer.

Objective To suvey the clinical application of antibacterials and drug resistance of antibacterials in the hospital in 2013.Methods To make statistical analysis on the frequency of drug use and drug resistance rate in 2013.Results Piperacillin wasn′t used in 2013 in the hospital.No hemolytic streptococcus was detected with drug resistance.Drug resistance rate of Esche-richia coli to piperacillin was 33.22%.Conclusion Bacterial resistance might be related to the using frequency of drugs and the types of antibacterials used in a region.

Differentiated thyroid cancer (DTC) is the most common type of thyroid cancer. Most of patients with DTC are characterized by low invasiveness and good prognosis. With the development of medical imaging, fine needle biopsy and molecular biology technology, especially the progress of surgical technology, the early diagnosis rate of DTC and the survival rate after operation are significantly increased. However, the cognition understanding of DTC and some views of surgical treatment are still controversial. A systematic review and summary of the diagnosis and surgical treatment of DTC are made based on the changes in the past 40 years, especially the treatment strategy, surgical resection scope and indications of DTC primary focus and cervical lymph node metastasis, in order to propose a more reasonable and accurate individual diagnosis and treatment plan for patients with DTC.

Objective:To evaluate the clinical significance of emergency surgical application shock index in patients with severe trauma complicated with hemorrhagic shock and its guiding first aid nursing.Methods:A total of 52 patients from the First Affiliated Hospital, Sun Yat-sen University with severe trauma complicated and hemorrhagic shock were divided into observation group and control group (each group with 26 cases) according to stratified random sampling method. The patients in the control group received the corresponding routine nursing measures, and the observation group carried out evaluating the severity of the condition by shock index based on the corresponding emergency nursing measures. The emergency time, consultation time, prognosis and the nursing satisfaction of the two groups were compared.Results:The emergency time, consultation time were (30.1 ± 3.7), (2.7 ± 0.7) min in the observation group and (39.6 ± 4.2), (3.8 ± 0.9) min in the control group, the differences were statistically significant ( t values were 8.097, 5.149, P<0.01). The cure rate was 73.1%(19/26) and effective rate was 15.4% (4/26) in the observation group, those index was 57.7% (15/26) and 23.1% (6/26) in the control group, the difference was statistically significant ( Z value was 2.969, P<0.01). The high nursing satisfaction was 65.4% (17/26) and nursing satisfaction was 26.9% (7/26) in the observation group, while 30.8% (8/26) and 53.8% (14/26) in the control group, the difference was statistically significant ( Z value was 2.493, P<0.05). Conclusions:Applying shock index to evaluate the corresponding nursing measures can shorten the time of emergency and separate diagnosis, and improve the overall nursing effect of emergency surgery.

External beam radiotherapy (EBRT) is one of the important treatment of thyroid cancer. EBRT is still controversial in some aspects of differentiated thyroid cancer. With the development of radiotherapy technology, improvement of equipment and accuracy, treatment complications caused by EBRT are significantly reduced. As a result, EBRT is valued again in the treatment of thyroid cancer, and its indications have been broadened. How to improve the curative effect and guarantee the quality of life becomes the focus of attention. EBRT may be an effective treatment for specific stage and pathological type of thyroid cancer. The multidisciplinary approach is expected to benefit more patients in the future.
