Objective To characterize 16S rRNA methylase encoding genes associated with aminoglycoaides resistance, gene cassettes of class Ⅰ integrons of the multidrug-resistant Acinetobctcter spp. The sixty one Acinetobacter isolates were collected at the Second Hospital of Shanxi Medical Uni versity from July, 2007 to May, 2008. Methods Species identification was confirmed by sequence analysis of the blaOXA-51-like gene and 16S-23S rRNA gene space-region. Antimierobial susceptibility tests were performed by agar dilution method. 16S rRNA methylaae encoding genes and gene cassettes associated with integrons were amplified by PCR method. Results Among the sixty one strains, there were fifty five of Acinetobacter baumannii, three genospecies 3TU, one 13TU, one Aeinetobaeter ealcoacetieus, and one Aeinetobaeter haemolytieus. Forty eight isolates showed high-level resistance to three aminoglyeosides, including amikaein, tobramyein and gentamicin. The armA gene was found in 47 isolates and all isolates were negative for rmtA, rmtB, rmtC and rmtD genes. The Intl gene was found in 27 isolates. The gene cassettes contained arr-3, accA4,ctacCI ,catB8, aadA1 or dfrA12 genes. According to the PFGE DNA patterns, 5 distinct clones of armA-pasitive strains were identified. Clone A and Clone B were the dominant clones, widely distributed among different divisions. Condnsions 16S rRNA methylase encoding gene (armA) distributed widely in muhidrug-resistant Acinetobacter spp. The armA gene is not located in class Ⅰintegron. The class Ⅰ integron carries multiple resistant genes associated with aminoglycosides and chloramphenieol resistance.PFGE analysis suggests that armA-pesitive strains are widely spread in our hospitaL Effective infection control measure should be conducted in order to control the outbreak of resistant bacteria.

OBJECTIVETo study the effects of continuous cropping obstacles on growth of Rehmannia glutinosa.

METHODThe growth indexes, activity of root ATPase, root activity and mineral nutritional absorption were determined.

RESULTContinuous copping decreased growth rate and declined the size of leaves. Activity of root ATPase and root activity were also inhibited.

CONCLUSIONThe deficiency of source capacity is an important factor to restrain the root development of R. glutinosa with continuous cropping, the decrease of root activity and ATPase activity as well as nutritional stress of potassium and nitrogen are the reasons for the effects of continuous cropping on the growth and development of R. glutinosa.

OBJECTIVETo determine 5 phenolic acids in the soils around rhizosphere of Rehmannia glutinosa in the field under normal rotation and successive cropping.

METHODPhenolic acids related to allelopathy effect in the soils around rhizosphere of R. glutinosa were determined by HPLC.

RESULTThe growth of R. glutinosa under normal rotation was strong. During harvest, the dry weight of the root tube and the volume of the R. glutinosa under normal rotation were 6.02 and 7.71 times of the ones under successive cropping.

CONCLUSIONThe seeding stage and elongating stage are the crucial periods for the autotoxic effect of the R. glutinosa under continuous cropping. During these periods, the content of coumaric acid, 4-hydroxybenzoic acid, syringic acid, and ferulic acid of R. glutinosa under successive cropping are notably negative correlation with the growth of the leaf and root tuber of R. glutinosa under successive cropping. Among them, ferulic acid plays a major role in the restriction effect on R. glutinosa under successive cropping.

OBJECTIVETo determine whether the sonic hedgehog (Shh) signaling could regulate the expression of histone demethylases in the head and neck squamous cell carcinoma(SCC).

METHODSHuman recombinant SHH-N protein or over-expression of the mutant 2 smoothened (M2-SMO) was applied to activate the Shh signaling in tongue squamous cell carcinoma cell line-SCC-6 in this study. Cyclopamine was used to block the Shh signaling in SCC-6. The real-time reverse transcription (RT)-PCR was used to detect the expression of histone demethylases at the mRNA level.

RESULTSThe data showed that activation of the Shh signaling up-regulated the expression of histone demethylase, lysine-specific demethylase 8 (KDM-8) at the mRNA level by human recombinant SHH-N protein (1.841 ∼ 3.591 fold compare with untreated group; P < 0.01), over-expression of the M2-SMO also increased the expression of KDM-8 (1.358 ∼ 3.013 fold compared with empty vector group; P < 0.05), and after the Shh signaling was blocked by Cyclopamine, the expression of KDM-8 was down regulated (decreased 25.6% ∼ 66.6% compared with control cells, P < 0.05).

CONCLUSIONSHistone demethylase KDM-8 was downstream target gene of Shh signaling in head and neck squamous cell carcinoma cell line SCC-6, and its expression was positively regulated by the Shh signaling.

Objective To investigate the clinical, electromyographic and cervical magnetic resonance imaging (MRI) characteristics of Hirayama disease. Methods Fifteen patients with Hirayama disease were observed for special clinical manifestations and underwent electromyographic examination of the bilateral distal upper limb muscles and peripheral nerve conduction velocity. MRI of the neck in neutral and fully flexed positions was performed to identify potential lower cervical cord atrophy and cervical curvature anomalies. Results All the 15 male patients had disease onset during puberty with asymmetric muscular atrophy and weakness of the hands and forearms. Concentric needle electromyography revealed prolonged duration and large amplitude of the motor unit potentials in the compromised distal limb muscles with also increased polyphasic potentials and poor recruitment, involving mainly the C7, C8 and T1 myotomes. In neutral neck position, MRI identified lower cervical cord atrophy in 9 patients, occurring mainly at C5, C6 levels;in fully flexed position, all patients showed forward displacement and flattening of the lower cervical cord, occurring mostly at C6 level. Conclusion Hirayama disease occurs mainly in puberty in young male patients, whose clinical features and electromyographic examination often indicate localized anterior horn anomalies in the lower cervical cord. MRI of the neck in neutral and fully flexed position can provide valuable assistance in the diagnosis of this disease.

OBJECTIVETo observe different effects of moxibustion on extracellular potassium ion in acupoint under physiological and pathological status and provide experimental evidence for exploring action mechanism of moxibustion on acupoint local.

METHODSForty female SD rats were randomly divided into a blank group, a blank-moxibustion group, a model group and a model-moxibustion group, 10 cases in each one. The complete Freund's adjuvant(CFA) was adopted to establish model of adjuvant arthritis (AA) in the model group and model-moxibustion group. No treatment was given in the blank group and model group while moxibustion was applied at "Zusan-li" (ST 36) for 30 min in the blank-moxibustion group and model-moxibustion group. The tissue fluid in "Zusanli" (ST 36) was collected with microdialysis and real-time analyzed by electrolytic analyzer. The change of concentration of potassium ion in "Zusanli" (ST 36) was observed.

RESULTS(1) Under physiological status, the concentration of extracellular potassium ion in the blank group was not changed within 150 min (P > 0.05); before the moxibustion, the concentration of extracellular potassium ion in the blank-moxibustion group was (1.21 +/- 0.31) mmol/L, and after treatment it was gradually increased and reached its peak at (2.38 +/- 0.42) mmol/L after 60 min (P < 0.05), then it was reduced. 150 min after the treatment, concentration of potassium ion was slightly higher than that before moxibustion as well as that in the blank group. The concentration in the blank-moxibustion group at 60 min was statistically significant compared with that in the blank group (P < 0.05). (2) Under pathological status, the concentration of extracellular potassium ion in the model group was not changed within 150 min, differences of which at each time point was not statistically significant (all P > 0.05). Before the moxibustion, the concentration of extracellular potassium ion was (1.09 +/- 0.12) mmol/L in the model-moxibustion group, and it was immediately increased to (1.96 +/- 0.18) mmol/L after moxibustion. 60 min and 90 min after the moxibustion, it still maintained a higher level, which was (1.87 +/- 0.29) mmol/L and (1.59 +/- 0.16) mmol/L respectively (both P < 0.05). The differences of each time point after moxibustion in the model-moxibustion group were statistically significant compared with those in the model group (all P < 0.05).

CONCLUSIONThe moxibustion could increase the concentration of potassium ion in rat's acupoint local under physiological status but time of effect is short; with moxibustion at "Zusanli" (ST 36) under pathological status, the concentration of local potassium ion is obviously increased and maintains for a long time.

OBJECTIVETo investigate the mixed infection and analyze risk factors in children with severe adenovirus pneumonia.

METHODSA retrospective analysis was performed on the clinical data of 756 children with adenovirus pneumonia between June 2009 and June 2011. Pathogens and risk factors were studied in 216 severe cases.

RESULTSOf the 216 severe cases, 138 (63.9%) were aged from 6 months to 2 years, and 161 (74.5%) developed the disease in the winter and spring; 177 (81.9%) were affected by 1-4 pathogens besides adenovirus, including 74 cases (34.3%) infected with one pathogen as an addition. A total of 334 pathogen strains were identified from the respiratory secretions and sera of the 216 cases. Of them, 163 (48.8%) were bacterial strains, dominated by Gram-negative bacteria (124 strains), 108 (32.3%) were viral strains, and 40 (12.0%) were fungal strains. Multivariate logistic regression analysis indicated that congenital heart disease, congenital airway abnormalities, nutritional anemia, recurrent pulmonary infection, and surgical history were the independent risk factors for severe adenovirus pneumonia in children, with odds ratios of 3.3, 11.1, 7.2, 14.3 and 12.9 respectively (P<0.05).

CONCLUSIONSSevere adenovirus pneumonia is mostly seen in children aged from 6 months to 2 years and occurs frequently in the winter and spring. Many cases are also infected with other pathogens, most commonly Gram-negative bacteria. Congenital heart disease, congenital airway abnormalities, nutritional anemia, recurrent pulmonary infection and surgical history are the independent risk factors for severe adenovirus pneumonia in children.

The effect of growth and fermentation conditions on the production of catalase by T. aurantiacus WSH 03-01 was investigated in shaking flasks. Catalase activity reached 1594 u/mL when the culture was grown on a complex carbon source containing 20 g/L dextrin and 1% (V/V) ethanol, which was 23% higher than the sum produced on 20 g/L dextrin and 1% (V/V) ethanol, respectively. It was concluded that dextrin might act as a major carbon source in the complex, while ethanol was rather a stimulator than a carbon source. The stimulation effect of ethanol on catalase production was postulated to be two aspects; catalase-dependent alcohol metabolism is activated by acute alcohol, thus more catalase need to be synthesized for that use, named direct induction. As for indirect induction, which may result from little amount of H2O2 generation in process of NADH regeneration in respiratory chain. Peptone was shown to be a favorable nitrogen source for catalase production and its optimum concentration was found to be 10 g/L. Catalase production by T. aurantiacus WSH 03-01 was further improved by optimizing the initial pH, volume of medium in flasks as well as the concentration of external H2O2. Under the optimum culture conditions, the activity of catalase reached 2762 u/mL, which was nearly 6.8 times higher than that of the initiate conditions. Furthermore, the potential application of this novel catalase in the treatment of textile bleaching effluents was evaluated. Thermo-and alkaline stability of this catalase was compared with the commercial available catalases produced from bovine and Aspergillus niger. The crude enzyme from T. aurantiacus WSH 03-01 showed stronger stabilities at (70 degrees C, 80 degrees C, 90 degrees C) and (pH 9.0, pH 10.0, pH 11.0) than the other two types of catalases, indicating a great application potential in the clean production process of textile industry.
