Objective To explore the clinical value of dynamic electrocardiogram ( DCG) in the diagnosis of coronary artery damage (CAD) in children with Kawasaki disease (KD).Methods A total of 125 cases of children with KD admitted to hospital in recent years was analyzed , without CAD as the control group (83cases), and others as the experimental group (42cases).All cases were undertaken DCG and electrocardiogram (ECG).The results of heart rate, heart Rhythm, and voltage changes were compared be-tween two groups .Results The abnormal rate of total ECG and DCG in the control group was significantly lower than the experimental group ( P <0.01 ) , The total ECG and DCG abnormal rate was no difference in control group ( P >0.05 ) , but DCG abnormal rate of experimental group was significantly lower than ECG (χ2 =15.30, P <0.01).The sensitivity, specificity, Youden index, and diag-nostic accuracy of normal ECG , DCG and Joint were 59.5%, 86.7%, 0.463 , and 77.6%;95.2%, 94.0%, 0.892 , and 94.4 %;95.2%, 84.3%, 0.796 , and 88.0%.Common ECG results were lower than DCG and joint ( P <0.05 ) , But DCG results were sim-ilar with the joint ( P >0.05 ) .Conclusions DCG test provides scientific parameter in the diagnosis of CAD in children with KD , and is superior to normal ECG , but the value of Joint is the same .

Objective To explore a new training method of nursing skills under 24 hours shift system in the practical training base in the college. Methods The practical training base in the college was rebuilt into a simulated hospital. 120 three-year-course nursing students in grade 2007 were divided into the control class and the experimental class with 60 students in each class. The control class adopted routine teaching method, including teacher demonstration, single project training, concentrated training before clinical practice. The experimental class participated in the tutoring mode of nursing skills under 24 hours shift system in simulated hospital. The cases were pre-designed and students acted as patients by tums. One teacher led 4 students into nursing skill training by day shift, evening shift and mid-night shift. The teaching effect was compared between two classes. Results There was significant difference between the two groups in comprehensive technique test and graduation theoretical test score. Clinical nursing teachers thought the skill training in simulated hospital under 24 hours shift system can help students prepare for the nursing work in hospital ahead of time and improve their comprehensive capability. Conclusions Training mode of nursing skills in simulated hospital under 24 hours shift system is feasible for enhancing nursing skills.

In our previous work, we found that trivalent dimethylarsinous acid (DMA(III)) have high affinity binding to cysteine residue 13 of rat hemoglobin. However, it is still unknown why arsenic intermediate metabolite DMA(III) has high binding affinity for Cysl3 but not for other cysteine residues 93, 140, 111 and 125. In order to better understand the molecular mechanism of DMA(III) with rat hemoglobin, we have done current study. So, SD rats were divided into control and arsenic-treated groups randomly. Arsenic species in lysate of red blood cells were analyzed by HPLC-ICP-MS, and then determined by a hybrid quadrupole TOF MS. In addition, trivalent DMA(III) binds to different cysteine residues in rat hemoglobin alpha and beta chains were also simulated by Molecular Docking. Only Cys13 in alpha chain is able to bind to DMA(III) from the experiment results. Cys13 of alpha chain in rat hemoglobin is a specific binding site for DMA(III), and we found that amino acids compose pockets structure and surround Cys13 (but not other cysteine residues), make DMA(III) much easy to bind cysteine 13. Taken together, the DMA(III) specific binding to Cys13 is related to spatial structure of Cys13.

Objective To develop a real-time fluorescence quantitative PCR method for detection of Legionella pneumophila as a tool for environmental and clinical examination. Methods A pair of degen-erated primers and one TaqMan-MGB probe were designed to test the conserved region at the macrophage in-fective potentiation (mip) gene of Legionella pneumophila. TaqMan MGB real-time quantitative PCR assay was developed with pMD-19T plasmid including mip gene of Legionella pneumophila as standard sample. The sensitivity and specificity of the real-time quantitative PCR was evaluated using the standard sample and dif-ferent strains. Results The detection limit of 0.71 copy/μl was obtained for the standard sample in a reac-tion system of 0.6μl of sense and antisense primers (20μmol/L), respectively, 0.4μl of probe (20μmol/L) and 6.0μl of DNA temple. Conditions for the PCR reactions were as follows. After an initial de-naturation at 95℃ for 20s, 40 amplification cycles were performed. Each cycle consisted of denaturation at 95℃ for 10 s, primer annealing at 50℃ for45s. The PCR Ct value of a standard strain and 12 isolates was in a scale of 13.23 and 16.04. However, the Ct values of the strains of Staphylococcus aureus, Salmonella typhimurium, Vibrio parahaemolyticus, Escherichia coli, Pseudomonas aeruginosa and Shigella sonnei were greater than 30. Conclusion The real-time quantitative PCR method has good sensitivity and specificity and the result has potentiality of applying for detecting Legionella pneumophila.

To explore the impact of Salmonella on Enterococcusfaecalis isolate N41 under the coexisting,the growth traits and the transcription of 26 virulence genes of N41 at various growth phases were detected.Salmonella and/or N41 were inoculated and done plate counting,then growth curves were drawn and bacterial total RNA were extracted at given time points,quantitive realtime PCR was used to analyze the RNA transcription levels of 26 virulence genes of N41.The result showed that comparison with single incubation,the bacteria concentration of N41 dropped about 3.9 times,and Salmonella dropped about 110-times.Among 26 virulence genes of N41,the RNA transcription levels of 12 virulence genes such as ebpA,ebpC,rnjB,ace,ebpR,psr and so on were promoted at the four growth phases,but the RNA transcription levels of SlyA and sprE were dropped.Except that the RNA transcription levels of CylL-S,CylL-L,efaA and AS had no significant changes at the four growth phases,the mostly rest genes increased dramatically at post-log phase.This indicated that when incubated together,N41 inhibited the growth of Salmonella significantly,and Salmonella promoted the transcription levels of virulence genes of N41 as a whole.The results lay a foundation for further research on the interaction between bacteria species and the pathogenicity mechanism of Enterococci.
