RESUMO

Objective@#Ultrasound imaging is well known to play an important role in the detection of thyroid disease, but the management of thyroid ultrasound remains inconsistent. Both standardized diagnostic criteria and new ultrasound technologies are essential for improving the accuracy of thyroid ultrasound. This study reviewed the global guidelines of thyroid ultrasound and analyzed their common characteristics for basic clinical screening. Advances in the application of a combination of thyroid ultrasound and artificial intelligence (AI) were also presented.@*Data sources@#An extensive search of the PubMed database was undertaken, focusing on research published after 2001 with keywords including thyroid ultrasound, guideline, AI, segmentation, image classification, and deep learning.@*Study selection@#Several types of articles, including original studies and literature reviews, were identified and reviewed to summarize the importance of standardization and new technology in thyroid ultrasound diagnosis.@*Results@#Ultrasound has become an important diagnostic technique in thyroid nodules. Both standardized diagnostic criteria and new ultrasound technologies are essential for improving the accuracy of thyroid ultrasound. In the standardization, since there are no global consensus exists, common characteristics such as a multi-feature diagnosis, the performance of lymph nodes, explicit indications of fine needle aspiration, and the diagnosis of special populations should be focused on. Besides, evidence suggests that AI technique has a good effect on the unavoidable limitations of traditional ultrasound, and the combination of diagnostic criteria and AI may lead to a great promotion in thyroid diagnosis.@*Conclusion@#Standardization and development of novel techniques are key factors to improving thyroid ultrasound, and both should be considered in normal clinical use.

RESUMO

Objective To investigate the phenotypes and expression of activated T-cell membrane molecules on lymphocytes in the peripheral blood(PB) of children with aplastic anemia (AA) and find out its clinical significance.Methods The lymphocytes from PB of the 115 AA patients were analyzed by flow cytometry and compared with normal group.Results The expression of CD8+ increased and the expression of CD4+ decreased. The ratio of CD4/CD8 cells decreased ,and was more significant in the patients with serious AA(SAA). The expression of HLA-DR and ??T-cell also increased, and was more significant in SAA patients. The expression of CD3+ was not significantly changed.Conclusions There is significant immune abnormal in AA patients and more important in SAA patients. The immunosuppressant is useful in clinical treatment.
