Thyroid hormones play major roles in the regulation of a wide range of metabolie and physiologic processes.Serum thyroid-stimulating hormone( TSH ) concentration,a sensitive barometer of thyroid function,shows significant individual difference in which genetic variation is a major factor.After using traditional genetic linkage studies and candidate gene association studies to explore the suseeptibility genes of serum TSH,many progresses have been made and new susceptibility genes have been identified by genome-wide association study (GWAS).In this review,we focus on the susceptibility genes of serum TSH levels and also the future prospect that may be obtained from these studies.

Conclusion The method is applicable to determination of nitromethane,nitroethane,1-nitropropane,2-nitropropane in the air of workplace.

The supramolecular inclusion properties of beta-cyclodextrin (beta-CD) and resveratrol (Res) were investigated using drug-protein interaction spectroscopy method. The differences between the results of interaction spectroscopy method and the results of classical method were compared. The total energy of the stable inclusion of cyclodextrin-resveratrol was calculated by Gaussian theory calculation. The stable inclusions in the process of interaction between resveratrol/inclusion complex and bovine lactgoferrin (BLF) were studied by molecular modeling. The results showed that the interaction spectroscopy method could explain the property of the inclusion in a more sensitive manner, it also interpreted the conveying mechanism of BLF binding with inclusion complex. The molecular modeling result showed consistent results with Gaussian theory calculation; both of the two methods obtained the stable configuration of beta-CD-Res inclusion. The relevant result provided an experimental consequence for the pharmacology research of beta-cyclodextrin-resveratrol inclusion complex as well as offering a new reference to the future research of supramolecular inclusion compound.

[Summary] A total of 1 510 subjects undergoing physical examination in the Central Hospital of Xuzhou were included in this study. According to the level of TSH, the subjects were divided into low TSH group(0. 30-0. 99 mIU/L,n=351), moderate TSH group(1. 00-1. 89 mIU/L, n=703), and high TSH group(1. 90-4. 80 mIU/L, n=456). Analysis of variance and linear regression were used for data analysis. The results showed that systolic blood pressure ( SBP) , diastolic blood pressure ( DBP) , triglyceride ( TG) , and high-density lipoprotein cholesterol( HDL-C) revealed significant differences among 3 group(P<0. 05 or P<0. 01). In the univariate linear regression model, serumTSHwithinthereferencerangewasnegativelyassociatedwithSBPandDBP(P<0.05orP<0.01),and positively associated with TG and HDL-C (P<0. 05 or P<0. 01). However, the correlations disappeared after adjustment for gender, age, body mass index, fasting plasma glucose ( FPG ) , and TG. In the multiple linear regression model, a significant negative correlation of TSH with SBP and FPG was found in males(P<0. 05).

Objective To investigate the association of the expression level of anti-apoptosis protein p-AKT and gastric mucasal injury induced by indomethacin in mice.Methods The cytotoxicity induced by indomethacin was measured by LDH assay.The p-AKT expression levels were measured in the gastric mucosal tissues from C57BL/6 mice and rat gastric mucosal (RGM-1) cell lines treated with indomethacin lay western blotting.Results The cytotoxicity induced by indomethacin was in a dose dependent manner.Compared with the control,a typical histological appearance of gastric ulcer was observed in the gastric mucosa of in domethacin-administered mice;p-AKT protein expression in the gastric mucosa of mice and RGM-1 cell lines was decreased after treated with indomethacin.Conclusion The reduction of Anfi-apoptesis protein p-AKT expression may be a new mechanism for the gastric mucosal injury induced by indomethacin.

Objective To inactivate Death-associated protein kinase 1 gene (DAPK1) by transfecting complementary methylated oligonucleotides and studies its effect on the proliferation of myelogenous leukemia cell line K562. Methods Methylated oligonucleotides complementary to DAPK1 gene promoter were transfected into K562 cells by Iipo2000. Methylation specific PCR (MSP) and Reverse transcription PCR (RT-PCR) were applied to detect DAPK1 gene promoter methylation status and its mRNA expressions respectively. MTT was used to detect the proliferation of K562 cells pre- and post- oligonucleotides transfection. Results DAPK1 gene promoter in non-treated and control groups were unmethylated with detectable mRNA expressions, but it became methylated with inhibited mRNA expressions after methylated oligonucleotide transfection. Proliferation in methylated oligonucleotide treatment group was significantly higher than that in non-treated and control groups. Conclusion Complementary methylated oligonucleotides could inactivate DAPK1 gene and inhibit its expression in K562 cells, which could promote its proliferation.

Objective To explore the correlation of the gene polymorphism of the two single nucleotide polymorphisms(SNPs)rs1443434andrs925489onforkheadboxEl(FOXE1)withthehighnormalthyroidstimulating hormone ( TSH) level in Chinese Han population. Methods 1 400 subjects with normal serum TSH and thyroid peroxidase antibody(TPOAb) levels were included. According to TSH or TPOAb levels, the subjects were divided into high normal TSH group(H-TSH group,n=195) and normal TSH control group(TSH control group,n=1 205) or high normal TPOAb group ( H-TPOAb group, n=711 ) and low normal TPOAb group ( L-TPOAb group, n=689 ) , respectively. The genotypes on the two SNPs of all the subjects were performed by whole-genome genotyping chips. Results There were significant differences in rs925489 genotypic distributions and allele frequencies between H-TSH group and TSH control group(both P<0. 05). The genotype TT and allele T in H-TSH group were significantly higher than those in TSH control group(89. 75% vs 83. 15%, 94. 62% vs 91. 29%). The normal TSH levels were positively associated with rs925489 genotypic distributions after adjustment for sex, age, and high density lipoprotein cholesterol(P<0. 01). There were no significant differences in rs1443434 genotypic distributions and allele frequencies between two TSH groups or two TPOAb groups. Conclusion FOXE1 rs925489 gene polymorphism may be correlated with the high normal TSH level in Chinese Han population.
