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

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 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 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

Objective To determine the median effective target effect-site concentration (EC50) of sufentanil inhibiting responses to insertion of laryngeal mask airway (LMA) when combined with propofol in the elderly patients.Methods ASA physical status Ⅰ or Ⅱ patients,aged 66-75 yr,with body mass index of 19-30 kg/m2,scheduled for elective transurethral resection of prostate under general anesthesia,were included in this study.Anesthesia was induced with propofol given by target-controlled infusion.The initial target effect-site concentration (Ce) of propofol was 1 μg/ml,and the Ce was increased by 0.5 μg/ml every 1 min until it was increased to 2 μg/ml and maintained at this level for 5 min.Sufentanil was simultaneously administered by target-controlled infusion.The target Ce of sufentanil was 0.3 ng/ml in the first patient.The concentration of sufentanil was determined using the modified Dixon's up-and-down method.After the patients lost consciousness,LMA was inserted after the target effect-site and plasma concentrations were balanced.The insertion response was defined as positive when MAP and HR increased by 20％ of the baseline value within 5 min after insertion of LMA.The Ce of sufentanil was increased/decreased in the next patient if the insertion response was positive or negative.The ratio between the two successive concentrations was 1.2.The EC50 and 95 ％ confidence interval of sufentanil blunting responses to insertion of LMA was calculated using Probit analysis.Results When combined with propofol,the EC50 (95％ confidence interval) of sufentanil blunting responses to insertion of LMA was 0.160 (0.130-0.188) ng/ml.Conclusion The EC50 of sufentanil inhibiting responses to insertion of LMA is 0.160 ng/ml when combined with propofol in the elderly patients.

Objective To study the effects of high albumin, high glucose and low bovine serum on the phenotypic transformation of renal tubular epithelial cells. Methods The normal human kidney proximal tubular eel] line (HKC) was cultured for 30 days in the presence of high albumin (1.5 g/L), high glucose(25 mmol/L) and low bovine serum(2% ) . Morphological changes were observed by electronic microscopy. Immunohistochemistry stain was used to examine the expression of cytokeratin, vimentin, a-SMA, collagen Ⅰ and TGF-pl protein. Western blot was applied to further detect the process of collagen I protein expression, and in situ hybridization was used to examined the expression of collagen Ⅰ gene. Results Renal tubular epithelial cells cultured in high albumin, high glucose and low bovine serum showed obvious morphologic changes, including elongated shape, decrease of microvilli and mitochondria, and increase of rough endoplasmic reticulum under electronic microscopy. Immunohistochemistry stain revealed the reduction of cytokeratin, and enhancement of vimentin, ?-SMA, TGF-?1 and collagen Ⅰ. Western blot demonstrated that the expression of collagen Ⅰincreased in a time-dependent manner, and in situ hybridization showed that collagen type Ⅰ mRNA increased as well. Conclusion High albumin, high glucose and low bovine serum induce phenotypic transformation of renal tubular epithelial cells into mesanchymal cells.
