131 I-metabolizing genes are markers for differentiation of thyroid carcinoma.The loss or down-regulation of these genes represents progression of dedifferentiation,which results in low 131 I uptake and suggests a poor prognosis.The mechanism of dedifferentiation of DTC is important for treatment.This article reviews the mechanism of dedifferentiation from 131I radiation damage,gene mutation,tumor markers and protein.

Objective To detect the expression of selenium binding protein 1 ( SBP1 ) in gastric cancer cell line SGC7901, BGC823, normal gastric epithelial cell line GES-1, gastric cancer tissues and normal gastric tissues, explore the relationship between SBP1 and pathologic features, and discuss the feasibility of SBP1 as an diagnostic marker of gastric cancer. Methods The clinical data of 135 patients with gastric cancer who were admitted to Zhongnan Hospital of Wuhan University from 2006 to 2007 were retrospectively analyzed. The expression of SBP1 in the gastric cancer tissues and 16 cases of normal gastric tissues were detected by immunohistochemistry. The mRNA and protein expressions of SBP1 of SGC7901, BGC823 and GES-1 were determined by Western blot and RT-PCR. All data were analyzed by using chi-square test and one-way analysis of variance.Results The mRNA expressions of SBP1 in BGC823 and SGC7091 were 0. 120 ± 0. 020 and 0. 133 ± 0. 015,respectively, which were significantly lower than 0. 907 ± 0. 015 in GES-1 ( F = 2106. 462, P ＜ 0.05 ). The protein expression of SBP1 in BGC823 and SGC7901 were 0.253 ±0.015 and 0.273 ±0.015 ,respectively, which were significantly lower than 0.877 ±0.025 in GES-1 ( F = 1026. 758, P ＜0.05 ). A strong positive reaction of SBP1 was observed in 3 cases of gastric cancer tissues and 16 cases of normal gastric tissues. The decrease of the protein expression of SBP1 was correlated with clinical stages of the patients ( x2 = 12. 629, P ＜ 0.05 ), rather than the sexes, ages, tumor histological types, tumor differentiation, infiltration depths and lymph node metastasis (x2 =2. 142, 0.860, 1.838, 5.001,4.858, 1.994, P＞0. 05). Conclusions The decrease of SBP1 expression could be used as a marker in diagnosing gastric cancer. Down-regulation of SBP1 expression may play an important role in the genesis and prognosis of gastric cancer.

Protein-protein binding is the basis of virus and host cell interactions. With the application of technology of studying protein interactions, more knowledge of replication and pathogenesis of hepatitis C virus (HCV) was acquired. Non-structure protein 5B(NS5B) of HCV is a kind of viral protein, which plays an important role in replication of HCV. However, the effect of NS5B is not clear. To investigate the biological function of NS5B, we performed yeast two hybrid to look for proteins in hepatocytes interacting with NS5B. We constructed NS5B bait plasmid by cloning the gene of NS5B into pGBKT7, then transformed it into yeast AH109(a type). The transformed yeast was mated with yeast Y187(? type)containing liver cDNA library plasmid in 2?YPDA medium. Diploid yeast was plated on synthetic dropout nutrient medium (SD/-Trp-Leu-His-Ade) containing x-?-gal for screening. Thirty-three colonies were selected and sequenced. Among them, two colonies were new genes with unknown function. The preliminary successful cloning of gene of protein interacting with NS5B paved the way for the study of the physiological function of NS5B and its associated protein.

Objective To investigate the related risk factors and neonatal outcomes in early preterm birth by analysis of 198 cases of early-to-moderate preterm birth. Methods Retrospective analysis was conducted on 198 pregnant women hospitalized during January 2004 to September 2006 with early-to-moderate preterm birth who delivered at 28 to 33+6 weeks of gestational age and their preterm infants.All of them were divided into two groups: early preterm birth group,28 to 3l+6 weeks of gestational age,n=90 for the pregnant women and n= 99 for the preterm infants;moderate preterm birth group,32 to 33+6 weeks of gestational age,n=108 for the pregnant women and n=122 for the preterm infants(fatal birth defects were excepted).The risk factors for preterm birth and neonatal outcomes were compared between the two groups. Results Various factors contributed to the occurrence of preterm birth.Systemic antenatal care and weight gain during pregnancy were significantly less found in the early preterm birth group than the moderate preterm birth group(P

Background and purpose:Thyroglobulin antibody (TgAb) is often positive in papillary thyroid carcinoma (PTC) patients. This study aimed to investigate the effect of TgAb on radioiodine ablation efficacy in PTC patients.Methods:A total number of 329 PTC patients with no distant metastasis were included and classified into 2 groups[G1 group (>115 U/mL,n=84) and G2 group (<115 U/mL,n=245)], G2 group was further divided into 2 subgroups[S1 (>40 U/mL,n=31) and S2 (<40 U/mL,n=214)], before131I ablation. The median follow-up time was 24 months after a total or subtotal thyroidectomy and subsequent131I ablation. The efficacy in terms of131I ablation success rates (IBR) between two groups were compared and the influencing factors were analyzed according to criteria posed by 2015 American Thyroid Association Guidelines, then the effect of131I dose on IBR was also explored.Results:Female and younger age were more prevalent in patients with high TgAb (P<0.05). The G1 group presented lower IBR over the G2 group (35.7%vs 72.7%,P=0.000). Moreover, S1 group also presented lower IBR over S2 group (54.8%vs 75.2%,P=0.017), indicating the adverse effect from high titer TgAb on IBR. No matter high or low dose, the G1 group presented lower IBR (34.1%vs 71.9%, 37.2%vs 73.2%;P=0.000). However, IBR did not differ in G1 or G2 group either with high or low dose131I (P>0.05). TgAb was the only adverse indicator correlating with IBR in multi-logistic regression analysis (P=0.018).Conclusion:TgAb could negatively affect131I ablation efficacy, while increasing the dose of131I failed to improve the success rate in such cases.
