3.Advances in Diagnosis and Treatment of Differentiated Thyroid Cancer in Patients Showing Thyroglobulin Elevative and Iodine Scintigraphy Negative.
Journal of Biomedical Engineering 2015;32(3):707-711
Thyroglobulin (Tg) and radioiodine whole body scan (WBS) have been commonly used in follow-up of patients with differentiated thyroid carcinoma (DTC). Tg is associated with radioiodine uptake in local or distant metastases. In minority of patients, the follow-up scan shows no functioning thyroid tissue, but the serum thyroglobulin is still elevated. Therefore, we review recent developments of diagnosis and treatment of those patients with differentiated thyroid cancer and with thyroglobulin elevation but negative iodine scintigraphy.

Chinese Journal of Nuclear Medicine and Molecular Imaging 2015;(6):428-433
Objective To evaluate the value of speckle tracking imaging( STI) by investigating the correlation and consistency between two?dimensional STI and 99 Tcm?MIBI G?MPI in the assessment of myo?cardial injury and myocardial infarction ( MI) of swine model. Methods Eight healthy and same?age adult female Tibetan swine were used to establish animal models of MI induced by open?chest ligation of the first diagonal branch of the left anterior descending coronary artery. The swine underwent ultrasonic cardiogram and G?MPI before and at 6, 24, 48, 72 and 96 h after the operation. The myocardial perfusion was evalua?ted. Ultrasonic sectional graphs were collected to analyze ultrasonic short?axis horizontal peak values of sys?tolic radial strain ( SR) and systolic circumferential strain ( SC) and local myocardial rotation angle ( Rot) of different segments of the left ventricle with off?line STI. Left ventricular ( LV) EDV, LVESV, LVEF by G?MPI and ultrasonography were compared. Pearson correlation analysis and repeated measures analysis of variance were used. Results Six models were successfully constructed. Six hours after the coronary artery ligation, the G?MPI showed no significant or very few perfusion defects;24, 48, 72 and 96 h after the liga?tion, G?MPI showed sparseness and defects at the anterior septum, anterior and lateral wall of apical seg?ment of apical segment. The peak strain values of SR, SC and Rot at the anterior septal apical segment, the anterior and lateral wall of apical segment decreased at different time points after the ligation. Six hours after the coronary artery ligation, the STI was positive. For healthy swine, the LVEF measured with G?MPI and ultrasonic STI showed good correlation ((68±3)% vs (70±4)%, r=0.84, P<0.05). The LVEF values of G?MPI and ultrasonic STI at 6, 24, 48, 72, 96 h after the ligation were (79±1)%, (80±4)%, (58±2)%, (54±4)%, (57±4)%, and(76±2)%,(76±3)%,(57±3)%,(55±3)%,(68±6)% (r:0.40-0?76, all P<0.05). LVEDV and LVESV measured by the two methods showed variation trends at different time points ( F=64.104, 30?069, 35.186, 54.903, all P<0.01) with good consistency after the ligation. Conclusions Ultrasonic STI could estimate the myocardial injury at an earlier stage and measure the severity of damaged myocardium quantitatively, and the resluts are in good agreement with myocardial perfusion and function by G?MPI.

Lung metastases are more common in metastatic disease in differentiated thyroid carcinoma (DTC). Because of its insidious onset and slow development, clinical diagnosis is relatively difficult. Some possible diagnostic methods for detecting the lung metastasis of DTC including serological examination, radionuclide imaging and other medical imaging patterns are discussed in this paper. The progress and the current situation about investigation of those modalities which are in the early diagnosis, recurrent and clinical evaluation for the lung metastasis of DTC are briefly reviewed. Therefore, it is expected to promote DTC with lung metastasis to a higher diagnostic level.

Objective To study the effect of different prostaglandin E2 (PGE2) combined with tumor necrosis factor-?(TNF-?) to the IP3-Ca2+ pathway mediated by membrane TNF-?R of fibroblasts. Methods The lung fibroblasts of breed mouse were primarily cultured. 10 ?g/L TNF-? and 10 ?g/L TNF-? combined with PGE2 of different doses were added to culture medium of fibroblasts. At some observation time,the expression of TNF-?R on the cellular membrane of fibroblasts was detected by the method of immunohistochemistry,the level of IP3 in cells was detected by the method of radioimmunoassay and the contents of Ca2+ in fibroblasts by the method of flow cytometry. Results With doses of PGE2 increasing at 30 s time point and 60 s time point,the cpm value of IP3 of fibroblast decreased gradually. The cpm value of IP3 significantly increased when the dose of PGE2 was 1.0 ?g/L,but obviously lower when the dose of PGE2 was 2.0 ?g/L at 120 s time point. The expression of TNF-?R and the contents of Ca2+ decreased in a dose-dependent way with the dose of PGE2 increasing. Conclusion Certain dose of PGE2 could suppress the effect that TNF-? enhance the cell proliferation of fibroblast by the IP3-Ca2+ pathway mediated by membrane TNF-?R of fibroblasts.

BACKGROUND:There are many reports on the effects of low-to-moderate intensity endurance exercise on mitochondrial biogenesis in the skeletal muscle, but there is no understanding about the high-intensity endurance exercise. It has not been reported whether the high-intensity endurance exercise influence the mitochondrial biogenesis in the skeletal muscle through 5′-adenosine monophosphate-activated protein kinase (AMPK)/silent information regulator factor 2 related enzyme 1 (SIRT1) signal molecules. OBJECTIVE: To investigate the effect of AMPK/SIRT1 signaling cascade on the mitochondrial biogenesis in the skeletal muscle during different intensities of endurance exercises. METHODS:Forty-two male Sprague-Dawley rats were randomly divided into sedentary group, moderate-intensity exercise group and high-intensity exercise group. Moderate-intensity exercise load was 28 m/min, 60 min/d;high-intensity exercise load was 38 m/min, 60 min/d. In both exercise groups, the rats had 5 days of exercise and 2 days of rest within 1 week, and the exercise lasted for totaly 7 weeks. The animals of exercise groups were kiled immediately, 6 hours and 24 hours after exercise. Quantitative PCR was used to detect peroxisome proliferators γ activated receptor coativator-1α (PGC-1α) and SIRT1 gene expression, and western blot to detect phosphorylated-AMPK (P-AMPK) and SIRT1 protein expression. RESULTS AND CONCLUSION:(1) Immediately, 6 hours, 24 hours after moderate-intensity exercise, PGC-1α mRNA expression in the skeletal muscle was 362% (P < 0.01), 675% (P < 0.01) and 116% of that in the sedentary group, P-AMPK protein expression was 112%, 165% (P < 0.05), 129% (P < 0.05) of that in the sedentary group, the expressions of SIRT1 protein and mRNA were 55% (P < 0.05), 86%, 103% and 109% (P < 0.05), 155%, 132% (P < 0.05) of those in the the sedentary group, respectively. (2) Immediately, 6 hours, 24 hours after high-intensity exercise, PGC-1α mRNA expression in the skeletal muscle was 274% (P < 0.01), 130% (P < 0.05), 68% (P < 0.05) of that in the sedentary group, the expression of P-AMPK protein was 235% (P < 0.01), 166% (P < 0.05), 160% (P < 0.05) of that in the sedentary group, the expressions of SIRT1 protein and mRNA were 199% (P < 0.01), 166% (P < 0.05), 164% (P < 0.05) and 255% (P < 0.01), 292% (P < 0.01), 122% of those in the sedentary group, respectively. These findings indicate that (1) 7 weeks of moderate-intensity endurance exercise significantly increased PGC-1α gene expression in the skeletal muscle, and its mechanism may involve AMPK/SIRT1 signaling cascade; (2) 7 weeks of high-intensity endurance exercise significantly inhibited PGC-1α gene expression at 24 hours after exercise,and this process was carried out in an AMPK/SIRT1 signal cascade independent manner.
