Objective To investigate the changes of iodide uptake and the expression of thyroidspecific genes in poorly differentiated follicular thyroid carcinoma (FTC) cells after transfection of human TSH receptor (hTSHR) gene in vitro. Methods The recombinant eukaryotic expression plasmid PcDNA3. 1/hTSHR-cDNA was transformed into DH5a bacterial for amplification and then the recombinant plasmid was extracted. The recombinant was identified with PCR amplifying, restriction enzyme digestion analysis and DNA sequencing. The recombinant plasmid pcDNA3.1/hTSHR was transfected into FTC-133 cell line by lipofectin methodin vitro. Immunofluorescence, iodide uptake studies and real time-PCR were applied to detect target protein expression. Statistical analysis was performed with t-test using SPSS 13. 0 software. Results Kpn Ⅰ and Xba Ⅰ restriction enzyme digestion, PCR amplifying and DNA sequencing confirmed that pcDNA3. 1/hTSHR was successfully constructed. After transfection of the recombinant plasmid pcDNA3. 1/hTSHR-cDNA and the stimulation of hTSH, the tumor cells displayed the expression of hTSHR protein at cell surface and cytoplasm. The iodine uptake in pcDNA3. 1/hTSHR transfected cells was 2. 9 times higher than that of control(pcDNA3.1(+) transfected cells) group(t = 28.63, P <0. 01). The expression of TSHR,NIS, TPO and Tg (mRNA levels) in pcDNA3. 1/hTSHR transfected cells were also significantly elevated by 1.74 (t =5.959, P<0.01), 7.2 (t =3.807,P<0.05), 2.88 (t=4.769,P<0. 01) and 2.67 times (t=6.388,P <0.01) respectively compared to those of the control group. Conclusion The study demonstrates that iodide uptake may be reactivated by hTSHR receptor gene transfection in poorly differentiated FTC cell.

Objective To evaluate the effect of transcatheter arterial chemoembolization (TACE) and delayed surgery for infant hepatoblastoma.Methods TACE was performed with the initial digital subtractive angiography (DSA) under general anesthesia 1-3 times in 8 infants with huge hepatoblastoma, whose age was 2 to 12 months. DSA was done via arterials in hepatoblastoma each time before chemoembolization. The arterials were perfused with chemodrugs and suspensions in ultrasome iodized oil , and were blocked with spring rings. DSA findings indicated that the tumor shrank without new tumorous arterials after 1 month in 6 cases, and 4 of them showed no tumorous staining, and the delayed surgery was performed successfully 1 week later in 6 infants. One boy underwent systemic chemotherapy alone during 6 months after 3 times of TACE. Results TACE therapy did not encounter any major technical problem or toxic reaction caused by chemotherapy. The following DSA test 4 weeks later did not detect any new tumorous vessels in 6 cases. Six children received TACE and surgery had been followed-up with no tumor recurrence for months averagely. The boy underwent TACE and venous chemotherapy for 6 months , without surgery , had been followed-up for 48 months until the present report. CT, AFP and DSA did not show any hints of tumor recurrence. Six cases receiving 3 times TACE combined with surgery survived without tumor recurrence. Conclusions TACE is a very effective, safe and helpful therapy for hepatoblastoma, which stressed the repeated use of spring ring to block tumor vessels lastingly if necessary. If surgery is required, DSA test is needed beforehand to detect new tumorous vessels or neoplasm. If there is any , TACE is repeated. TACE combined with surgery may provide an additional promising choice in the treatment of hepatoblastoma, and repeated TACE alone may cure hepatoblastoma in infants.
