ObjectiveTo study the correlation with Genes Coding forESBLs and ClassⅠIntegron in ESBLs-producing Escherichia coli from children.MethodsPCR was used for gene typing detection of 100 strains of ESBLs-producingEsche-richia colistrains. While detection of class I integrase gene in the 100 strains ESBLs-producingEscherichia coli and 100 strains of non-ESBLs producingEscherichia coli were separately performed by PCR. It provides the solid base not only to reveal the relationship between class I integron and drug resistance, but also the relationship between class I integron and ESBLs-producing. ResultsThe most frequently genotyping from ESBLs-producingEscherichia coli in children isCTX-M (84%), followed by TEM-1(63%). The predominant distribution of genotype in ESBL- producing strains isTEM-1 +CTX-M (45%), followed by CTX-M (34%). Class I integrase gene detected in ESBLs- producing and non- ESBLs producing strain were 100 cases (100%) and 25 cases (25%) separately, the difference was statistically signiifcant (P<0.05); drug resistance in class I integron positive strains were signiifcantly higher than in class I integron negative strains, especially in Ciprolfoxacin, Levolfoxacin, and Amino-glycoside (86.4%, 88%, and 80%).ConclusionsThe distribution of Class I integron in ESBLs-producingEscherichia coli is signiifcantly higher than that in non-ESBLs-producing strains, It is rational that Class I integron highly correlate with strong drug resistance in ESBLs-producing strains.

Objective To investigate the effect of gefitinib on mucus hypersecretion by inhibiting epidermal growth factor receptor (EGFR) activity in chronic obstructive pulmonary disease (COPD).Methods Human airway epithelail cell lines 16HBE cells were exposed to cigarette smoke extraction (CSE) to establish the COPD model.EGFR activity was inhibited by tyrosine kinase inhibitor gefitinib.The mRNA expressions of EGFR and MUC5AC were detected by real-time PCR.EGFR,p-EGFR and MUC5AC protein levels were determined by Western blot and ELISA.Results EGFR mRNA level was increased by 12.7％ in CSE and 8.6％ in gefitinib group,but had no significant differences among CSE,gefitinib group and control group (all P＞ 0.05).MUC5AC mRNA levels were enhanced by 141.7％,26.4％ in CSE group and gefitinib group respectively,and there were significant differences among CSE,gefitinib group and control group (all P＜0.05).EGFR protein levels were (600.34±64.58) μg/mg,(632.58±72.94) μg/mg,(584.57±67.39) μg/mg,in control,CSE and gefitinib groups,respectively,and there were no significant differences between groups (all P＞0.05).p-EGFR protein levels were (338.62±45.28) μg/mg,(679.43±78.23) μg/mg,(292.74±59.17) μg/mg in control,CSE and gefitinib groups,respectively.MUC5AC protein levels were(72.80±6.25)μg/mg,(187.00±±10.26)μg/mg,(92.57±8.32)μg/mg in control,CSE and gefitinib groups respectively.Compared with control group,p-EGFR and MUC5AC protein levels were increased significantly in CSE group (both P＜0.05),and had no significant differences in p EGFR and MUC5AC protein levels between control group and gefitinib group.Conclusions CSE may lead to mucus hypersecretion through activating the EGFR-mediated signaling pathways.Gefitinib may inhibit mucus hypersecretion by inhibiting EGFR tyrosine kinanse activity.EGFR may serve as a potential target for COPD.

Objective To evaluate the feasibilities and advantages of different concentrations of sodium alginate (SA) solutions as a submucosal injection solution for endoscopic submucosal dissection (ESD). Methods In vitro study, different concentrations of sodium alginate solutions and normal saline were injected into submucosal of resected porcine esophagus and stomach respectively, then observe and measure the heights of each injection induced mucosal elevations, and their changes over time. In vivo study, the mimic ESD were conducted in healthy pigs to evaluate the mucosal elevation effect and other assistant effects of sodium alginate as a submucosal injection solution. Results The elevation heights of the experiment groups injected with SA solutions were much higher than the control group injected with normal saline. Specially, the elevation created by 1 % SA in porcine esophagus was significantly higher than that of normal saline (P < 0.01) and the elevation created by 3 % SA was significantly higher than that of normal saline in porcine stomach (P < 0.001). In the mimic ESD experiment, mucosal elevation with clear margin occurred immediately after injection with SA solution. And the durable submucosal fluid cushion created by SA protected deeper tissues while facilitating ESD procedure. Conclusion The elevation heights created by SA solutions were greater and more durable than that created by normal saline, which were crucial for ESD. The viscosity property enabled SA to form a stable protective cushion and prevent bleeding by squeezing tissue around the wound, which may decrease perforation and bleeding rate during ESD procedure. Therefore, sodium alginate can be an ideal clinical submucosal injection solution.

Objective To summarize the clinical characteristics and make genetic diagnosis in the patients with hereditary spinocerebellar ataxia type 7 (SCA7).Methods Pedigree analysis and clinical examination were performed in one family with SCA7 by clinical findings,of which retinal morphology and visual electrophysiology were available on part numbers.The polymorphic cytosine adenine guanine (CAG) repeats in the encode region of SCA7 gene were detected by combining polymerase chain reaction with deoxyribonucleic acide (DNA) sequencing on 19 familial numbers and 12 controls.Results 6 patients were identified,who manifesting cerebellar ataxia,decreased visual acuity and colour vision defect,as was pigmentary retinopathy on fundoscopy;The 6 patients had not only extinction of the electroretinogram (ERG) but also remarkably reduced amplitudes of oscillatory potentials and flash-visual evoked potentials. On normal alleles CAG repeat size ranges from 8 to 25 repeats,wherease on mutated alleles of the 6 numbers it ranges from 50 to 97 repeats.The 6 numbers were diagnosised as SCA7 patients.One asymptomatic individual of this family,who displayed a normal allele with 18 CAG repeats and another containing abnormal expantion of 56 repeats,was diagnosised as a asymptomatic carrier whose age maybe still below the age of onset.Conclusion The clinical manifestations of SCA7 are heterogeneous,and the detection of CAG repeats can provide an effective way for the gene diagnosis and the prediction of asymptomatic patients.
