Purpose To detect the expressions of stress induced phosphoprotein 1 (STIP1) and estrogen receptor-α(ER-α) in papil-lary thyroid carcinoma and to analyse the relationship between STIP1 and ER-α. Methods 54 cases of paraffin-embedded tissues of papillary thyroid carcinoma, 18 cases of papillary thyroid carcinoma with lymph node metastasis, 15 cases of Hashimoto’ s thyroiditis, 10 cases of adjacent normal thyroid tissue were collected. The expressions of STIP1 and ER-αwere detected by immunohistochemistry, and the relationship between the expressions and clinicopathological features of papillary thyroid carcinoma was analyzed. Results The expression of STIP1 and ER-α in papillary thyroid cancer group ( 55. 6% and 44. 4%) were higher than that of normal thyroid group (10% and 0) and Hashimoto’s thyroiditis group (8. 3% and 0, all P<0. 05). STIP1 expressions was related to lymph node metastasis ( P<0. 05 ) , while ER-α expression was related to gender, TG-Ab and the merger of nodular goiter, but not related to lymph node metastasis (P>0. 05). The expressions of STIP1 and ER-α in papillary thyroid carcinoma were not related to patients’ age , tumor location, number of tumors, tumer size, invasion of capsule, the concomitant Hashimoto’ s thyroiditis and TPO-Ab ( all P>0. 05). And the expressions of STIP1 was not related to gender, TG-Ab and the merger of nodular goiter (all P>0. 05). A positive correlation was found between the expressions of STIP1 and ER-αin thyroid papillary carcinoma (P<0. 05). Conclusion STIP1 and ER-α in papillary thyroid carcinoma may be related with lymph node metastasis.

Objective:To investigate the expression and clinical significance of wild-type p53-induced phosphatase 1 (Wip1) in thyroid carcinoma and biological effect of siRNA-targeting Wip1 on the thyroid carcinoma cell line. Methods:Immunohistochemistry and reverse transcription polymerase chain reaction (RT-PCR) were performed to detect the expression of Wip1 in 73 specimens of thy-roid carcinoma tissues and normal thyroid tissues (5 cm away from the margin of thyroid carcinoma), respectively. Wip1 siRNA was transiently transfected into the papillary thyroid carcinoma cell by using a liposome-mediated method and then detected by RT-PCR and Western blot. Methyl thiazolyl tetrazolium (MTT) assay and flow cytometry (FCM) were also conducted to observe cell proliferation, cell apoptosis, and cell cycle. Results:The positive rates of Wip1 protein were 80.8%in thyroid carcinoma tissues and 9.6%in the nor-mal tissues (χ2=47.036, P<0.05). The relative mRNA contents of Wip1 were 0.665 ± 0.046 and 0.225 ± 0.039 in carcinoma and normal tissues, respectively;these results significantly differed between the two types (t=12.637, P<0.05). Significant correlation was not ob-served between Wip1 expression and other factors, such as patient's gender, age, and tumor size (P>0.05). However, significant correla-tions among Wip1 expression, lymph node metastasis, clinical stages and tumor differentiation (P<0.05) were observed. RT-PCR and Western blot results showed that K1 cell-transfected Wip1 siRNA exhibited a relatively lower expression than normal cells (t=17.039, t=14.637, P<0.05). MTT assay results showed that the K1 cells transfected with Wip1 siRNA showed a lower survival fraction, higher cell apoptosis, higher percentage of G0/G1 phases, and lower cell concentration in G2/M and S phases (P<0.05). Conclusion:Wip1 pro-tein and mRNA were increased in thyroid carcinoma and are correlated with lymph node metastasis, clinical stages and tumor differenti-ation. Wip1 may be involved in proliferation, apoptosis, and cycle of thyroid cancer cells.

Objective To investigate podocyte number, the expression of nephrin and transforming growth factor-β1(TGF-β1) in adriamycin-induced-nephropathy rat model and its significance. Methods The rat adriamycin nephrosis model was constructed to detect blood and urine biochemical indicators and observe the pathological changes of renal tissues by light microscope and electron microscope. The expression levels of nephrin and TGF-β1 as well as the podocyte number were examined at different time points by immunohistochemistry. Results The pathological changes of the renal tissues were obvious. Nephrin presented a weak signal at the end of the first week (P<0.05). TGF-β1 started to increase (P<0.05) while the podocyte number started to decrease at the end of the eighth week (P<0.05). Expression of nephrin was negatively correlated with the P<0.05) and serum creatinine (r=-0.71, P<0.05). Expression of TGF-β1 was blood urea nitrogen (r=0.62, P<0.05) and serum creatinine (r=0.59, urinary protein (r=-0.63, P<0.05), blood urea nitrogen (r=-0.72, P<0.05) and serum creatinine (r=-0.76, P<0.05); it was positively correlated with nephrin (r=0.78, P<0.01) but negatively correlated with TGF-β1 (r=-0.64, P<0.05). Conclusion The acute and chronic adriamycin nephrosis models were twice every two weeks. The genesis and development of proteinuria are closely related to the abnormal expression of nephrin. Focal segmental glomerulosclerosis occurs when the podocyte number decreases and TGF-β1 accelerates it.

To study the complete genomic sequence, genomic characteristics, and genetic variation of the bovine papillomavirus 2 genotype (BPV-2) Aks-01 strain at the molecular level, genotyping of this strain from the skin samples of cows in southern Xinjiang (China) was first detected by the polymerase chain reaction with FAP59/FAP64 primers. Based on the complete genome of the BPV-2 reference strain, specific primers and sequencing primers were designed, and the complete genome of the Aks-01 strain amplified and sequenced. Sequence analyses showed that genotyping of the Aks-01 strain belonged to BPV-2. The Aks-01 strain had the structural characteristics of BPV-2. The 7944-bp full-length genomic sequence of the Aks-01 strain was compiled using DNAStar™. The sequence of the Aks-01 strain had 98% similarity to the reference strain from GenBank. The Aks-01 strain was most closely related to BPV-1 and BPV-13. BPV-2, BPV-1 and BPV-13 were grouped within the genus Deltapapillomavirus. The Aks-01 strain is the first BPV-2 strain reported in southern Xinjiang.
