Objective To evaluate the variability of calculating thyroid volume by SPECT imaging at different time postinjection. Methods A total of 40 patients with Graves disease were enrolled in this prospective study using simple random sampling method. After intravenous injection of Na99TcmO4, all patients underwent planar and tomographic scintigraphy at different time points (5, 10, 15, 20, 25, 30, 45 and 60 min), and the planar or tomographic integral method were used to estimate thyroid volume. Data were analyzed by one?way analysis of variance, paired t test or linear correlation analysis. Results For thyroid volume esti?mated by planar imaging, the correlation coefficients between the different time points and 20 min were 0?717-0?819 (all P<0.05), and the CV was (18.38±5.31)%. For thyroid volume estimated by tomographic integral method, the correlation coefficients were 0.913-0.961 (all P<0.05), and the CV was (8.05± 3?19)%. Both the correlation coefficient and CV were statistically significant between the two methods ( t=-13.59, -11.29, both P<0.05) . Conclusions Tomographic integral method has better correlation and re?producibility in calculating thyroid volume compared with planar method.

Objective To synthesize 4 kinds of 111 In?TPP cations and evaluate their properties as tumor cationic radiotracers in vivo and in vitro. Methods DO3A?xy?TPP, DO3A?xy?mTPP, DO3A?xy?dmTPP and DO3A?xy?tmTPP were radiolabeled with 111 In;their lipid?water partition coefficients and in vivo and in vitro stability were evaluated. The binding affinities of 4 kinds of 111 In?radiotracers were determined in cell uptake and cell efflux assay using U87MG tumor cells. Biodistribution studies and γ imaging studies were performed using the athymic nude mice bearing U87MG human glioma xenografts to explore the biologi?cal properties of 4 kinds of 111 In?radiotracers. One?way analysis of variance was used. Results The labeling yields of 4 kinds of 111 In?radiotracers were all above 85%, and the radiochemical purity were all greater than 99% after purification. Binding assay in U87MG cells showed that 4 kinds of radiotracers had great binding affinity and cell retention ability, and 111In?DO3A?xy?mTPP had the best binding ratio (1?49%;F=177.8, P<0.05) . Gamma imaging and biodistribution results showed that the U87MG tumors could be clearly visualized by 111In?DO3A?xy?mTPP, 111In?DO3A?xy?dmTPP and 111In?DO3A?xy?tmTPP, and the liver uptake of the 3 tracers was lower than that of 111In?DO3A?xy?TPP. In particular, 111In?DO3A?xy?mTPP had the best tumor/liver ratio (0.13±0.05, 2 h postinjection;F=9.4, P<0?05). Conclusions The tumor?targeted ability of 111In?DO3A?xy?mTPP is better than those of 111In?DO3A?xy?dmTPP, 111In?DO3A?xy?tmTPP and 111In?DO3A?xy?TPP, suggesting that it has the potential to be a promising tumor cationic radiotracer.

Objective To improve the understand of the clinical characteristics of mycosis fungoides and provide guidance for the clinical work. Methods The clinical data of 21 patients with mycosis fungoides in our hospital were retrospectively analyzed including the ages at diagnosis, clinicopatholagic characteristics of skin lesions, systemic manifestation, misdiagnosis and treatment of these patients. Results The mean age was (57.3±2.31) years at the diagnosis. Most patients were at the stage of plaques. Clinical manifestations included generalized lesions (52.4 %) and itchy (66.7 %). Epidermotropism (66.7 %) and pautriers microabscesses(57.1%) were common histopathologic features. Previous misdiaguosis rate was 66.7 %. Skin targeted therapies and biologic therapies were effective approaches to relieve the skin rash at early stage, and combined chemotherapy was typically applied in more advanced cases. Conclusion Mycosis fungoides has various clinical characteristics and careful differential diagnosis should be made in clinical practice.

Objective To investigate the expression of syndecan-1 (SDC1) in glioma cells and the effects of synde?can-1 knockdown on the proliferation and invasion of A172 cells. Methods The expression of syndecan-1 in glioma cells was analyzed using quantitative Real-time PCR and Western blotting. A172 cells were transfected with lentiviral vector carrying SDC1 shRNA to establish a stable SDC1-silencing cell line. The cell proliferation was analyzed by MTT assay. Trypan blue exclusion assay and flow cytometry, and Transwell assays were performed to measure the migration and invasion abilities, respectively. The mRNA and protein and expression levels of SDC1, Proliferation Cell Nuclear An?tigen (PCNA) and Matrix Metalloproteinase 9 (MMP-9) were detected by using qRT-PCR and Western blotting. Results The expression levels of SDC1 were significantly different in different glioma cell lines. The stable SDC1-silencing cell line was successfully established, in which the mRNA and protein expression levels of SDC1 were significantly decreased (P<0.05). SDC1 knockdown significantly reduced the cell proliferation, migration(58.40±5.24 vs. 255.8±16.09、226.5± 22.84,F=126.4,P<0.05)and invasion(61.67 ± 16.26 vs. 233.70 ± 17.24、244.30 ± 28.15,F=69.87,P<0.05)compared with either control group or blank group. SDC1 knockdown also significantly decreased the mRNA and protein expression levels of PCNA and MMP-9 (P<0.05). Conclusion:SDC1 knockdown suppresses the capacities of proliferation, invasion and migration of glioma A172 cell, implying that SDC1 may serve as a novel target in the biotherapy of glioma.
