Background and purpose: The incidence of Hashimoto's disease (HD) coexistent with thyroid carcinoma is 0.5%-38%, and it is increased significantly in recent years. Therefore, we investigated the clinical characteristics and surgical experiences in patients with HD coexistent with thyroid neoplasm. Methods: The clinical data in 417 cases of HD coexistent with thyroid nodules including 93 cases of HD coexistent with thyroid carcinoma treated surgically and confirmed pathologically from Jun. 1985 to Dec. 2007 were analyzed. Results: The coexistent rate of HD with thyroid carcinoma (TC) was 22.3% respectively. The coexistent rate of HD with TC was 9.2% before 1995, and it went up to 24.7% after that year (P<0.05). Among those HD coexistent with TC patients, 66 cases were papillary carcinoma, 15 cases were follicular carcinoma, 9 cases were mixture and 3 cases were lymphoma. There were 43 cases of micro-foci thyroid carcinoma, which accounted for 46.2% of the malignancy. Unilateral or bilateral, total, subtotal or partial thyroidectomy and biopsy were the main operative procedures for the disease. Conclusion: There is a high incidence of thyroid carcinoma in patients with HD coexistent with thyroid nodules, and it is rising up recently. In the clinical treatment of HD, we should be aware of the coexistent thyroid tumors and micro-foci thyroid carcinoma.

Objective To observe the effect of X-ray radiation on NF-κB-HIF-1α pathway activation in three malignant lymphoma and to explore the mechanism of radioresistance mediated by this pathway.Methods Expression levels of p-P65,IKK and HIF-1α in Namalwa,Ramos and Raji cells were determined by Western blot 1,4,10 and 20 h after 5 Gy X-ray irradiation.The effect of QNZ on HIF-1α expression was also observed.Results Expression level of IKK protein was up-regulated 4 h after irradiation in the 3 lymphoma cell strains( t = 8.01,5.14,5.42,P ＜ 0.01 ),followed by up-regulation of p-P65 protein expression level at 10 h and HIF-1α at 10-20 h after X-ray irradiation (t = 11.25,17.43,22.09,P ＜ 0.01 ).Pretreatment of QNZ 24 h before X-ray irradiation significantly reduced the upregulation of HIF-1α protein expression induced by simple ion radiation ( t = 18.69,19.35,12.26,P ＜0.01 ).Conclusion NF-κB - HIF-1α pathway was activated in human lymphoma cells after ion radiation and may be involved in the mechanism of radioresistance.

Objective To explore if keratinocytes that stably maintain HPV11 genome can be obtained by transfection and selection methods. Methods Escherichia coil containing pBR322.HPV11 plasmid was cultured and amplified. Then the plasmid was extracted, purified and digested with BamH Ⅰ enzyme to release viral genome from the bacterial vector. After recovering from the low-melting point agarose gel by electrophoresis, the genome was self-circulated with T4 DNA ligase. The religated DNA was cotransfected with pTK-neo DNA into HaCaT keratinocytes using Lipofectamine reagent. After selection with G418 for 2 to 3 weeks, clonal and pooled cultures were expanded and analyzed. Fluorescent quantitative PCR (FQ-PCR) and nested reverse transcriptase PCR (nRT-PCR) were applied to detect HPV11 DNA and spliced HPV11 E1^E4 mRNA expression in the transfected cells. Results After the cotransfection of HPV11 genome into HaCaT keratinocytes and two-week selection,G418-resistant cell colonies were obtained with morphological features indistinguishable from normal HaCaT keratinocytes. As shown by FQ-PCR, HPV11 DNA was present in G418-selected HaCaT keratinocytes. The average viral DNA load capacity was 15.9±16.8 copies/cell in the primary culture of G418-selected HaCaT cells and 23.9±1.1 copies/cell in the third passage of the cells; there was no statistical difference between the two passages of cells (t=-0.822, P>0.05). nRT-PCR targeting HPV11 E1^E4 mRNA transcript produced a specific 628-bp fragment, which was shown by agarose gel electrophoresis. Conclusions Our data indicate that HPV11 genome can be successfully introduced into HaCaT keratinocytes by transfection and HPV11 DNA-positive cells can be obtained by G418 selection. Moreover, HPV11 DNA is still present in the third passage of transfected cells.
