Objective: To study the diagnostic value of color doppler ultrasound in children with thyroid nodules and thyroid cancer. Methods: A total of sixty children with thyroid nodules treated in our hospital from March 2017 to March 2018 were selected for study. All patients underwent color Doppler ultrasound diagnosis. According to the diagnostic data, benign thyroid nodules and thyroid cancer were analyzed. The nodule nature was grouped into benign nodules group and malignant nodules group. The aspect ratio and boundary of the two groups were compared in blurring, calcification, blood flow signal classification, etc. Results: A total of 95 nodules were diagnosed by color doppler ultrasonography in 60 cases of thyroid nodules. 49 cases were benign nodules. There were 80 nodules, accounting for 82.11%, 11 cases of thyroid cancer, and 15 nodules. Accounted for 15.79%. Biopsy puncture pathology confirmed 77 benign nodules and 18 malignant nodules. The pathological results were gold standard. The specificity of color Doppler ultrasound was 90%, the sensitivity was 66.67%, and the accuracy of ultrasound diagnosis was 86.32%.The two nodules were statistically significant in terms of boundary, aspect ratio, calcification, echo, and resistance index (P<0.05), but the end-diastolic blood flow velocity (EDV) and peak systolic blood flow velocity ( There was no statistical difference between the PSV levels (P>0.05).Conclusion: Color Doppler ultrasound has the advantages of simple operation, high accuracy, non-invasive and painless, and reproducible detection. The high-frequency probe can clearly display changes such as minute lesions, blood flow signals, echoes, calcifications, etc., and can diagnose thyroid cancer in time. It provides a favorable basis for clinical treatment and has important clinical warning value, especially for children with thyroid examination. 展开更多

The prognosis of small cell thyroid carcinoma(SCTC)in a large cohort has not been well reported in the literature.In this study,we analyzed the mortality of SCTC,in comparison to medullary thyroid cancer(MTC)and anaplastic thyroid cancer(ATC),based on the Surveillance,Epidemiology,and End Results(SEER)Program of the National Cancer Institute,to determine the prognosis of SCTC.Information regarding patients with a diagnosis of MTC,ATC,or SCTC,between 2004 and 2013,was acquired from the SEER database.Patient survival curves were assessed by Cox proportional hazards regression analyses,Kaplan-Meier analyses,and log-rank tests.In a Kaplan-Meier analysis of the entire cohort of thyroid cancer patients,cancer-specific survival declined sharply for patients with SCTC,but it declined more modestly for patients with MTC.The cancer-specific survival was not significantly different between SCTC and ATC.Unadjusted Cox regression analysis showed that SCTC had a higher cancer-specific mortality than MTC but a similar prognosis as ATC.SCTC showed a higher cancer-specific mortality than MTC and ATC after adjustments for various confounding factors.SCTC was found to have a more highly lethal clinical course than MTC and had a similar death rate to ATC.Therefore,we recommend that aggressive,radical treatment like surgery or radiation should be performed tor these patients. 展开更多

Objective:To explore the effect of selenium supplementation on thyroid function, immune response and oxidative stress in HT patients with normal thyroid function.Methods: A total of 120 Hashimoto's thyroiditis patients with normal thyroid function admitted to our hospital from June 2016 to March 2018 were randomly divided into treatment group and control group with 60 cases in each group. The control group was given oral placebo, while the treatment group was given selenium yeast. The expression levels of thyroid function [including thyroid stimulating hormone (TSH), free triiodothyronine (FT3) and free thyroxine (FT4)], immune response [including thyroid peroxidase antibody (TPOAb), thyroglobulin antibody (TGAb), interferon-γ (IFN-γ), interleukin-4 (IL-4)] and oxidative stress [including malondialdehyde (MDA), glutathione peroxidase (GPx) and superoxide dismutase (SOD)] were observed and compared between the two groups.Results: The two groups showed significant changes in auxiliary diagnosis, immune response and oxidative stress. Before treatment, there was no significant difference in the levels between the two groups. After treatment, there was no significant difference in the above indexes between the control group and that before treatment. There was no significant difference in thyroid function related indexes between the treatment group and the control group. The levels of TPOAb, TGAb, IFN-γ and MDA in the treatment group were significantly lower than those before treatment and in the control group, while the levels of IL-4, GPx and SOD were significantly higher than those before treatment and in the control group.Conclusions: Selenium supplementation can stabilize thyroid function, reduce the level of thyroid antibody production, and improve immune response and oxidative stress response in HT patients. 展开更多

Objective: Bethesda System for Reporting Thyroid Cytopathology(BSRTC) categories Ⅰ,Ⅲ, and Ⅴaccount for a significant proportion of fine needle aspiration cytology(FNAC) diagnoses. This study aimed to compare the diagnostic efficacy of BRAFV600E mutation and the Thyroid Imaging Reporting and Data System(TIRADS) classification in differentiating papillary thyroid cancers(PTCs) from benign lesions among BSRTC I, III, and V nodules.Methods: A total of 472 patients with 479 nodules were enrolled in this prospective study. Ultrasound, BRAFV600E mutation testing, and FNAC were performed in each nodule, followed by surgery or regular ultrasound examination.Results: In the BSRTC I category, BRAFV600E showed similar sensitivity, higher specificity, and lower accuracy when compared with TIRADS. In the BSRTC III/V category, the sensitivity, specificity, and accuracy of BRAFV600E were similar to those of TIRADS. In comparison to BRAFV600E alone, the combination of the two methods significantly improved sensitivity(BSRTC Ⅰ:93.6% vs. 67.7%, P < 0.01;BSRTC Ⅲ: 93.8% vs. 75.0%, P < 0.01;BSRTC V: 96.0% vs. 85.3%, P < 0.001). When compared with TIRADS alone, the combination improved sensitivity in BSRTC Ⅰ nodules(93.6% vs. 74.2%, P < 0.05), increased sensitivity and decreased accuracy in BSRTC III nodules(93.8% vs. 75.0%, P < 0.01, 91.0% vs. 93.6%, P < 0.01), and improved both sensitivity and accuracy in BSRTC V nodules(96.0% vs. 82.0%, P < 0.001;94.2% vs. 81.3%, P < 0.001).Conclusions: BRAFV600E exhibited higher specificity and lower accuracy compared with TIRADS in BSRTC Ⅰ nodules, while the two methods showed similar diagnostic value in BSRTC Ⅲ/Ⅴ nodules. The combination of the two methods distinctly improved sensitivity in the diagnosis of PTCs in BSRTC Ⅰ,Ⅲ, and Ⅴ nodules. 展开更多

Its role is well described in amphibian metamorphosis. Thyroid hormones (T3 and T4) have also been demonstrated to play a role in metamorphosis of marine invertebrates. However, the mechanism of thyroid hormone in metamorphosis of marine invertebrates remains unknown. A homolog of vertebrate thyroid hormone receptor (TR) was cloned and identified in abalone Haliotis diversicolor and was named HdTR . The mRNA expressions of HdTR , thyroid peroxidase ( TPO ), thyroid peroxidase 1 ( TPO1 ), idothyronine deiodinase Ⅲ( IDⅢ) and integrin alpha-V ( ITGAV ) had significant diff erence in metamorphosis of H . diversicolor . Metamorphosis rate and mortality rate were significantly diff erent in HdTR RNAi experiment and T3 inducing experiment. In RNAi experiment, ITGAV and CCND1 (cyclin D1) expression of dsRNA HdTR exposing group were significantly lower than those of blank control and negative control. But CTNNB (catenin beta) expression of dsRNA HdTR exposing group was higher than that those of blank control and negative control. ERK (extracellular signal regulated kinases) and PI3K (phosphoinositide-3-kinase) had no significant diff erence in RNAi experiment. Moreover, ITGAV of 1 μmol/L T3 group was significantly lower than that of 0 μmol/L T3 group, PI3K expression of 10 μmol/L T3 group was higher than that of 0 μmol/L T3 group, and the other genes expression had no significant diff erence in T3 inducing experiment. The data of genes expression suggested that CCND1 might be an eff ector gene of TR genomic action, while CTNNB might be regulated by unliganded TR. CCND1 and CTNNB may be involved in cell proliferation of metamorphosis. T3 might regulate the expression level of PI3K via nongenomic way. These results shed light on the mechanism of thyroid hormone in abalone metamorphosis. 展开更多

Ultrasound is a common imaging method for detecting cervical lymph nodes in PTC patients;however, it is not accurate in determining lymph node metastasis.AIM To evaluate the value of contrast-enhanced ultrasound combined with elastography in evaluating cervical lymph node metastasis in PTC.METHODS A total of 94 patients with PTC were recruited. According to pathological results,lymph nodes were divided into two groups: metastatic group(n = 50) and reactive group(n = 63). The routine ultrasound findings, contrast-enhanced ultrasound and elastography data were recorded and compared. Logistic regression was used to generate predictive probability distributions for the diagnosis of lymph node metastasis with different indicators. Receiver operating characteristic curve analysis was used to test the efficacy of contrast-enhanced ultrasound combined with elastography based on routine ultrasound in evaluating PTC cervical lymph node metastasis.RESULTS The ratio of long diameter/short diameter(L/S) ≤ 2, irregular marginal morphology, missing lymphatic portal, peripheral or mixed blood flow distribution, peak intensity(PI), non-uniform contrast distribution and elasticity score in the metastatic group were significantly higher than those in the reactive group(P < 0.05). L/S ratio, missing lymphatic portal, PI and elasticity score had a significant influence on the occurrence of PTC cervical lymph node metastasis(P< 0.05). Furthermore, the area under the curve(AUC) for lymph node metastasis diagnosed using the combination of PI ratio, elasticity score, missing lymphatic portal and LS was 0.936, which was significantly higher than the AUC for PI ratio alone. The difference was statistically significant(P < 0.05). The fitting equation for the combined diagnosis was logit(P) =-12.341 + 1.482 × L/S ratio + 3.529 ×missing lymphatic portal + 0.392 × PI + 3.288 × elasticity score.CONCLUSION Based on 展开更多

In the field of medical imaging,the traditional local binary pattern (LBP)and its improved algorithms are often sensitive to noise.Traditional LBPs are solely based on the signal information from local differences,and the binary quantization method oversimplifies the local texture features while disregarding the imaging information from the concaveconvex regions between the high-order pixels and the neighboring sampling points.Therefore,we propose an improved Derived Mean Complete Local Binary Pattern (DM_CLBP) algorithm based on high-order derivatives.In the DM_CLBP method,the grey value of a single pixel is replaced by the mean grey value of the rectangular area block,and the difference between pixel values in the area is obtained using the second-order differentiation method.Based on the calculation concept of the complete local binary pattern (CLBP)algorithm,the cascade signs and magnitudes of the two components are encoded and recombined in DM_CLBP using a uniform pattern.The results from the experiments showed that the proposed DM_CLBP descriptors achieved a classification accuracy of 94.4%.Compared with LBP and other improved algorithms,the DM_CLBP algorithm presented in this study can effectively differentiate between lesion areas and normal areas in thyroid MR,(magnetic resonance)images and shows the improved accuracy of area classification. 展开更多
