Objective To assess the relationship between single nucleotide polymorphisms of FcεRIαgene and atopic dermatitis. Methods Genomic DNA samples were extracted from peripheral blood of 97 patients with atopic dermatitis and 283 normal human controls. The polymorphism at the distal promoter region of FcεRIα gene was determined by PCR-ligase detection reaction assay followed by gene sequencing. Results A G/T polymorphism was observed at position rs61828219 in the promoter region of FcεRIα gene, while all the tested individuals were homozygous for T/T at position rs12135235 and A/A at position rs36233780 in the promoter region of FcεRIα gene. The mutation frequency at position rs61828219 was 1.04% and 2.17% in patients with AD and normal human controls, respectively (both P > 0.05). Conclusions In the Chinese Han population, there is a G/T polymorphism at position rs61828219 in FcεRIα gene promoter region, which is unlikely related to the development of AD; however, no polymorphism is detected at position rs12135235 or rs36233780.

Objective To Study the effect of thyroid peroxidase-Ab (TPO-Ab) on in vitro fertilization and embryo transfer (IVF-ET) ending. Methods From March 2011 to October 2013, a total of 378 assisted reproduction cycles in Reproductive Medical Center of Qinghai Provincial People ’s Hospital were retrospectively analyzed in. Experiment group included 69 cycles from patients with positive thyroid peroxidase antibody and normal thyroid function and control group 309 cycles from those with negative thyroid peroxidase antibody and normal thyroid function. Results IVF fertility rate (79.76%) and high quality embryo rate (46.59%) in experiment group were significantly lower than those in control group (84.08%, 54.49% respectively) and the difference was statistically significant (P < 0.05); abortion rate (33.33%) in experiment group was obviously higher than that in control group (16.11%), which was statistically significant (P < 0.05). Conclusion Positive thyroid peroxidase antibody exerts adverse effects on IVF-ET ending since TPO-Ab reduces IVF fertilization rate and high quality embryo rate and increases the rate of abortion.

OBJECTIVETo investigate the effect of different kinds of mechanical stress on the mRNA expression of integrin beta1 subunit in cultured human periodontal ligament fibroblasts (hPDLF).
METHODSTo scalp and remove the periodontal ligament attached to the mid-third part of the fresh root of young premolars extracted for the cause of orthodontics. Cultured hPDLF by the method of digesting by I-type collagenase combining with tissue adhering. Then hPDLF was isolated and purified by cells passage. The sixth passage's cells were selected to be loaded. A new cyclic strain loading apparatus. Forcel four point bending device was used for mechanically loading. Cells were loaded by three levels (1000, 2000, 4000 microstrain) of tensional and compressive forces and collected at different times (0, 0.5, 1, 4, 8, 12 h) course after strain loading. The quantity of integrin beta1 mRNA in every group was analyzed by means of quantitative real-time PCR with the special primers of up- and down-regulated genes.
RESULTSDynamic mechanical forces down-regulated the expression of integrin beta1 subunit mRNA in hPDLF and the difference in groups by different magnitude, different kinds, and different time of mechanical forces loading were statistically significant. The stronger stimulated forces, the more down-regulated expression. Compression down-regulated the expression of integrin beta1 subunit mRNA more than tension did.
CONCLUSIONDynamic mechanical forces could regulate the expression of integrin beta1 subunit mRNA. The difference among all the groups by different magnitudes, different kinds, and different time of mechanical forces loading were statistically significant.

OBJECTIVETo investigate the association between the polymorphism of potassium voltage-gated channel, Isk-related family, member 1 (KCNE1) gene and atrial fibrillation (AF) in Uigur patients of Xinjiang.
METHODSThree hundred and three patients with atrial fibrillation and 328 healthy controls were tested for the genotype for the KCNE1 gene SNP in the rs1805127 locus by polymerase chain reaction-restriction fragment length polymorphism. The risk factors were also included.
RESULTSThe genotype frequencies of AA, AG and GG were 0.092 (28/303), 0.386 (117/303) and 0.522 (158/303) in the AF patients while they were 0.122(40/328), 0.485 (159/328) and 0.393 (129/328) in controls. There was significant difference in frequencies of the three genotypes (chi-square was 10.465, P=0.005) and G allele (0.715 vs. 0.636, chi-square was 8.907, P=0.003) between the AF and control groups. Logistic regression analysis showed that the KCNE1 polymorphism was the main risk factor of AF in Uigur population. The OR value of genotype GG was 1.55, the 95% CI: 0.73-3.27.
CONCLUSIONFor Uigur population, genetic polymorphism of rs1805127 locus of the KCNE1 gene may increase the risk of atrial fibrillation.

Objective To investigate the effects of low contrast agent concentration and optimal monoenergetic image on myocardial image quality in dual source, dual energy coronary CT angiography (CCTA).Methods Sixty patients,who were clinically suspected of coronary heart disease and referred to perform dual energy CCTA examination,were prospectively collected between January and June 2016 in the first affiliated hospital of Xinjiang Medical University and then randomly divided into two groups with thirty cases in each group.Dual-energy CCTA was performed in both groups with the same parameters expect the iodine contrast agent concentration.The iopamidol concentrations were 370 and 320 mg/ml for groups A and B, respectively. The raw images of the two groups were reconstructed to get conventional mixed energy images and 60,65,70,75,80,85,90 keV single energy images,respectively labeled as group A1 to A8 and group B1 to B8.The CT attenuation,noise,signal-to-noise ratio(SNR)and contrast to noise ratio(CNR)were measured in images from groups A1 to A8 and B1 to B8. And the optimal monoenergetic image set was selected.Rank sum test was used to compare the CT value,noise,SNR and CNR between groups A1 to A8 and B1 to B8.The differences of above-mentioned parameters between A1 and B5 group,A5 group and B5 group were compared by independent sample t test.Results The differences of CT value,noise,SNR and CNR between groups A1 and A8, B1 and B8 were statistically significant (P<0.05). The CNR and SNR of group A5 were significantly higher than that of group A1,and the image noise of group A5 was lower than that of group A1(all P<0.05),and the images of A5 group(75 keV)were the optimal monoenergetic image. The SNR and CNR of the left ventricular lateral wall in group B5 were significantly higher than those in group B1,and the noise was lower than that in group B1(all P<0.05),and the image of B5 group(75 keV) was the optimal monoenergetic image. The difference of image noise between groups A1 and B5 was statistically significant(P<0.05),while the differences of SNR and CNR between these two groups were not significant(all P>0.05).The differences of image noise,SNR and CNR between groups A5 and B5 were not significant(all P>0.05).Conclusions The myocardial CCTA image quality by using iodine contrast agent (320 mg/ml) and optimal monoenergetic imaging (75 keV) is equivalent to that of conventional iodine contrast agent(370 mg/ml)mixed energy image.The strategy can effectively reduce the amount of contrast agent when meeting the needs of the clinical diagnosis.
