In recent years,a large number of researches show that the tumor related gene promoter hypermethylation is an important reason of esophageal adenocarcinoma and closely associated with the differentiation,invasion,metastasis,staging and prognosis of tumors.It might be used as a neww target for the clinical detection and therapy of esophageal adenocarcinoma.

Objective To investigate the changes of expressions of axon guidance molecule Sema3F and its receptor Np2 in hippocampus of temporal lobe epilepsy(TLE)rat.Methods Rats were injected with Lithium-chloride,Pilocarpine intraperitoneally to establish TLE model.The Sema3F mRNA,Np2 mRNA and protein in areas CA1,CA3 and dentate gyrus(DG)of hippocampus at different time were detected by immunohistochemistry and in situ hybridization for TLE models.Further,they were compared with normal control group.Results Compared with normal control group,the expressions of Sema3F mRNA,Np2 mRNA and protein in areas CA1,CA3 significantly decreased(P

Objective To analyze the allergens detection in asthmatic infants and young children. Methods The specific IgE test and allergens screening test were conducted in 243 infants and young children with whooping diseases including asthmatic bronchitis, asthmatic pneumonia and asthma by skin prick test and Pharmacia UniCAP test. Results 1. Food allergen was the allergen detection most frequently in infants(P = 0.03). The proportion of aeroallergens increased significantly with age (positive rate:67. 2%). Milk and egg white was the main food allergen detection in infants and young children,and the main aeroallergen detection was house dust mite. 2. The allergen - specific IgE test using UniCAP test system was more accurate than skin prick test. Conclusions The infants are more susceptible to food hypersensitivity; the increasing opportunity of aeroallergen exposure may lead to a higher prevalence of aeroallergens in young children. UniCAP system is more accurate than other methods.

Objective To survey the current status of job stressor and exhaustion among nursing staff in the catheter room of grade Ⅲ-A general hospitals and to look for regularities.Methods 178 nursing staff coming from catheter room,operating room,and outpatient department of Shenzhou Hospital and Fengtian Hospital accepted questionnaires of Chinese Nursing Stressor Scale and Exhaustion Scale in Spring 2010.Results Chinese Nursing Stressor Scale indicated that scores of subitem and total score of job stressor in the catheter room were significantly higher than those in the outpatient department; however,there were no significant differences in scores of subitem and total score of job stressor between catheter room and operating room.On the other hand,Exhaustion Scale showed that scores of emotional exhaustion and job unconcerned feeling in the catheter room were significantly higher than those in the outpatient department,but scores of job achieved feeling in the catheter room were significantly lower than those in the outpatient department.There were no significant differences in Exhaustion Scale between catheter room and operating room nurses.Conclusions Job stressor and exhaustion were serious among nursing staff in the catheter room of grade Ⅲ-A general hospitals,which should cause the attention of management department.

Objective To assess the subgenotypes of pathogenic Cryptococcus gattii isolates from China and to elucidate the epidemiological links between these domestic isolates and those from other parts of the world. Methods DNA was extracted from 9 clinical isolates of Ctyptococcus gattii from China. The partially variable regions of the three unlinked loci, namely IGS1, PLB1 and GEF1, were amplified and sequenced, and the bioinformation at these loci was obtained from GenBank for multi-locus sequences alignment and phylogenetic analysis. Results Of these 9 clinical isolates, 8 were genotype VG Ⅰ and mating type α with the same sequences at the tested regions as the reference strain WM276, which was a representative isolate of an independent subgenotype; 1 was of genotype VG Ⅱ and mating type α, which was the first report in China, with the tested sequences consistent with those of the referrence strain R272. Sequencing and phylogenetic analysis of GEF1 gene, which was located at mating type locus, successfully identified the genotypes and mating types of all the Cryptococcus gattii isolates involved here. Conclusions Multi-locus sequence analysis shows that causative Cryptococcus gattii isolates of genotype VG Ⅰ in China carry similar sequences at the tested loci in IGS1, PLB1 and GEF1 genes, to a widely distributed subgenotype in the world, and the sequences of the first VG Ⅱ genotype isolate from China resemble the less virulent subgenotype VG Ⅱ b found in Vancouver islands.

[Objective] To explore the feasibility and advantages of blood microdialysis technique for the pharmacokinetic study of sinomenine. [Methods] In this study, rats served as the experimental subjects and sinomenine was administered to the rats by intravenous injection. With microdialysis technique for blood sampling, the blood concentration of sinomenine was determined by high performance liquid chromatography (HPLC) and the associated pharmacokinetic parameters were analyzed by 3p97 program. [Results] The pharmacokinetics process of sinomenine in rats presented as the two-compartment model. The half-life of distribution phase was 10.98min and that of elimination phase was 44.71 min. [Conclusion] It is feasible to study pharmacokinetic parameters of sinomenine by using blood microdialysis technique. In comparison with the traditional technique, blood microdialysis technique is superior to the examination of drug blood concentration .

OBJECTIVE To retrospectively investigate the ciprofloxacin-resistance rate of Escherichia coli(ECO) and its main impact factors,and then guide empiric therapy for its infection. METHODS We looked up relative data in Hubei Network for Surveillance of Bacterial Antimicrobial Resistance.WHONET 5.2 Software was used to analyze resistance rates,and SAS software to perform univariate and multivariate Logistic regression assay. RESULTS Ciprofloxacin-resistance rate of ECO was and is on the rising,meanwhile,its resistance rates were different for laboratory,patient origin,age group,gender and so on,and the differences were all very significant(P
