OBJECTIVE To identify the antibiotic resistance,homology and the carbapenemases determinants of imipenem-resistant strains of Acinetobacter baumannii isolated from elderly in the Zhejiang Hospital.METHODS All 142 strains of A.baumannii were isolated from Zhejiang Hospital through Jan 2005 to Jan 2007.K-B method was used to screen imipenem-resistant strains.The MICs of imipenem-resistant strains to 14 antimicrobial agents were determined by agar dilution method.The homology of these isolates was analyzed by pulse-field gel electrophoresis(PFGE).The coding genes of carbapenamases and the gene environments were investigated by PCR,clone,and sequencing.RESULTS Ninety-seven strains of imipenem-resistant A.baumannii were isolated from 142 strains.All of the strains of carbapenem resistant A.baumannii belonged to 4 epidemic PFGE-clones.Ninety carbapenem resistant strains contained OXA-23-like carbapenemase gene and 91 isolates were positive for OXA-51-like gene. OXA-23-like gene of 86 strains was just on the down-stream of insert sequence ISAba1.OXA-51-like gene of 6 strains had an ISAba1 sequence just on the up-stream.CONCLUSIONS All imipenem-resistant strains of A.baumannii are pan-resistant isolates.Clone dissemination is the most important style of strains spread.No OXA-24-like,OXA-58like,IMP-like,and VIM-like gene are detected.OXA-23-like and OXA-51-like gene are the most popular carbapenemases coding genes of these strains in the Zhejiang Hospital.ISAba1 has close relationship with OXA type carbapenemases genes in Zhejiang Hospital.

ObjectiveTo explore the application value of two-dimensional ultrasonic measurement of fetal left and right lung area, left and right pulmonary longitudinal diameter, left and right lung volume and total lung volume in evaluation of fetal lung development.MethodsIn 489 cases of normal singleton pregnancy, two-dimensional ultrasound scanning were conducted at 12-40 weeks. The left and right lung area was traced in the four chamber view using Trace method. The distances of left diaphragmatic dome to left lung apex and the right diaphragmatic dome to right lung apex were measured respectively on the left and right fetal lung parasagittal planes. Then calculation of left and right lung volume and total lung volume was carried out.ResultsSpearman correlation coefficient of gestational age and left and right lung area, left and right pulmonary longitudinal diameter, left lung volume and total lung volume were 0.929, 0.923, 0.923, 0.917, 0.946, 0.943, 0.951, and a positive correlation, with statistical significance (P<0.05). At 12-40 weeks, fetal left and right lung area, left and right pulmonary longitudinal diameter, left and right lung volume and total lung volume increased with gestational age and fetal growth. Pulmonary area increased faster before 26 weeks than that after 26 weeks. Pulmonary longitudinal diameter and lung volume grew at a constant rate throughout pregnancy, but the growth rate of pulmonary longitudinal diameter was slightly faster than that of lung volume. The fifth, twenty-fifth, fiftieth, seventy-fifth, ninety-fifth percentile of fetal left and right lung volume and total lung volume at 12-40 weeks were obtained. ConclusionsFetal left and right lung area, left and right pulmonary longitudinal diameter, left and right lung volume and total lung volume were positively correlated with gestational age between 12 and 40 week. The normal values of lung volume and total lung volume provide a reference index for prenatal diagnosis of fetal pulmonary hypoplasia. The fetal four chamber view and fetal left parasagittal section was easy to obtain, and may serve as a new conventional method in evaluating fetal lung developments.

ObjectiveTo study possible differences in cognitive dysfunction between left hemisphere injury(LHI) patients and right hemisphere injury(RHI) ones.MethodsCognitive function of 55 LHI patients and 43 RHI patients were examined by aphasia screening test and the Loewenstein Occupational Therapy Cognitive Assessment Battery(LOTCA).ResultsThe scores of RHI group were significant higher than that of LHI group in orientation in place,overlapping figures,spacial perception,praxis(P<0.001-0.005),but significant lower than that of LHI group in visual identification of shapes and visuomotor organization(P<0.001-0.02).The possibilities of RHI group were significant more than that of LHI group in disorientation in time,shape agnosia,disorder in figure-ground identification,unilateral neglect,disordered attention(P<0.005-0.025),but significant fewer than that of LHI group in aphasia,ideomotor apraxia(P<0.005-0.01).The possibilities were no significant differences in disorientation in place,objects agnosia,colour agnosia,spacial agnosia,motor apraxia,constructional apraxia,thinking disorder between RHI group and LHI group(P>0.05).Conclusions There is characteristic cognitive dysfunction after right or left hemisphere injury.

Objective To investigate the histological and biochemical responses associated with periprosthetic osteolysis,including the changes of tumor necrosis factor-?(TNF-?),osteoprotegerin(OPG) and os- teoprotegeria ligand (OPEL) in the interface membrane in rat models so as to understand the mechanisms of these interactions.Methods Twenty-four male SD rats were used in this study.A titanium alloy plug was inserted into each distal femur through the knee joint.Polyethylene particles were injected into the left knee at 2,4,6,8 and 10 weeks after implantation of the plugs.Saline solution was injected into the right knee as the control.The animals were killed 12 weeks after implantation.The distal femur was taken from each knee to make histological sections. The samples were made decalcified and stained with hematoxylin and eosin.The histopathological changes were observed under a light microscope.The concentrations of TNF-?in the membrane were assayed by a ELISA kit and the mRNA expressions of OPG and OPEL extracted from the tissue around the plug were detected by RT-PCR. Results The interface membrane taken from the experimental side was found to contain extensive fibrous tissues which extended deeply into the surrounding hone.TNF-?concentrations in the membrane of the experimental side were higher than in the control membrane.There was a significant decrease of OPG mRNA and a significant increase of OPGL mRNA in the membrane around the plug at the experimental side compared with the control side.Con- clusions Polyethylene particles can induce inflammatory responses around the titanium alloy plug.The increase of OPGL expression and reduction of OPG expression in membrane at the experimental side may be induced by TNF-?. Such changes might contribute to the differentiation of osteoclasts and result in the periprosthetic osteolysis.

OBJECTIVEThe present study is concerning qualitative and quantitative detection of Poria cocos quality based on FT-near infrared (FT-NIR) spectroscopy combined with chemometrics.

METHODThe Poria cocos polysaccharides contents were determined by UV. Transmission mode was used in the collection of NIR spectral samples. The pretreatment method was first derivation and vector normalization. Then principal component analysis (PCA) was used to build classification model and partial least square (PLS) to build the calibration model.

RESULTThe results showed that conventional criteria such as the R, root mean square error of calibration (RMSEC), and the root mean square error of prediction (RMSEP) are 0.944 0, 0.072 1 and 0.076 2, respectively. The misclassified sample is 0 using the qualitative model built by PCA.

CONCLUSIONThe prediction models based on NIR have a better performance with high precision, good stability and adaptability and can be used to predict the polysaccharose content of Poria cocos rapidly, which can provide a fast approach to discriminate the different parts of Poria cocos.
