Journal of Modern Laboratory Medicine 2015;(2):114-116
Objective To investigate the clinical distribution and antibacterial drug susceptibility of mucoid Pseudomonas aeruginosa (mPa).Methods By looking at the patients’general information,disease information and the information of anti-microbial usage,cases of 53 strains of non-repetitive mucoid Pseudomonas aeruginosa were collected from hospitalized pa-tients from Jan 2013 to Dec 2013,and drug susceptibility were analyzed.Results A total of 53 strains of mucoid Pseudo-monas aeruginosa were isolated from sputum specimen,mainly elderly patients with a mean age of 66.7±9.1 years old;50 patients had chronic history of respiratory infections,all patients were used during the hospital stay of two or more kinds of antibiotics,used jointly only 11 cases of macrolides.All strains to commonly used antimicrobial agents showed a higher sen-sitivity in vitro,in addition to ticarcillin/clavulanate (64.2%),cefepime (60.4%),other drug sensitivity was higher than 70%.Conclusion Mucoid Pseudomonas aeruginosa was susceptible to chronic respiratory infection history of the elderly,its antimicrobial susceptibility was high in vitro,the use of antimicrobial agents in clinical was combined therapy compared,but utilization rate of macrolides drugs was low.

AIM: To explore the characteristics of motor evoked potential(MEP) and cortical excitability in Parkinson's disease by transcranial magnetic stimulation(TMS).METHODS: 20 normal volunteers were enrolled as control(group A),with the average age of(62.3?16.7) year old ranged from 52 to 79 years including 12 males and 8 females.MEP were assessed and compared separately between left and right hemispheres.21 patients with Parkinson's disease(PD) in asymmetry symptoms were performed in this study(group B),with the average age of(63.3?16.7) year old ranged from 46 to 80 years including 12 males and 9 females.UPDRS motor scores(UPDRSⅢ) were assessed before the check of cortical excitability(MEP).Motor evoked potentials(MEP) was assessed and compared separately on the minor and the serious bodyside,compared to control group.RESULTS: The indexes of MEP from both sides of normal control had no significant diversity.Amp was increased and both rest motor threshold(RMT) and cortical latency(CL) were also decreased significantly in PD patient compared to the normal control.On the serious side of PD,RMT decreased significantly compared to the minor side.Amp,CL and central motor conduct time(CMCT) changed without significant diversity between minor and serious bodyside.CONCLUSION: The motor cortical excitability is increased in PD patients.The excitability is higher with the more serious symptom side.The character of MEP in PD patients may be helpful to make a diagnosis and evaluate the severity of symptoms.

Objective To analyze the resenilin-1 (PS-1) gene mutations in Alzheimer' s disease (AD) patients and investigate the influence of the initiation codon mutation on the mRNA expression of PS-1 and amyloid precursor protein (APP) genes and the expression of PS-1 proteins.Methods (1) All 111 AD patients were enrolled by the Department of Neurology,Second Affiliated Hospital,College of Medicine,Zhejiang University from July 2004 to June 2010.Mutations in the 13 exons and flanking regions of PS-1 gene were examined by direct sequencing.(2) cDNAs encoding full-length wild-type and mutant (c.1A >G) PS-1 were subcloned into enhanced green fluorescent protein.Levels of the mRNA expression of PS-1 and APP genes and PS-1 proteins expression in the transfected cells were detected by quantitative real-time PCR and Western blot,respectively.Results A new heterozygous initiation codon mutation changing from ATG to GTG in one individual was identified.Compared to the control groups,the mRNA expression of the mutant PS-1 gene in HEK293 and N2a was significantly lower than the normal PS-1 gene(116.8 ± 3.9 vs 49.5 ±3.3,t =13.27,P <0.01 ;69.0 ± 1.9 vs 29.5 ± 1.3,t =17.20,P <0.01) and the APP gene was not obviously altered.The proteins were detected by Western blot analysis in HEK293 cells but not in N2a cells.Conclusions Since we only identified one novel heterozygous initiation codon mutation (from ATG to GTG),mutations in PS-1 are likely to be rare in AD patients.Initiation codon mutation would reduce the expression of PS-1 proteins.Inactivation of some of the PS-1 proteins could be insufficient to lead to AD and could be more likelv to act as a risk factor.
