OBJECTIVE To study the optimal reagent for regeneration of aptamer-coated piezoelectric quartz crystal chips and detect storage ability of aptamer-coated chips. METHODS Anti-IgE aptamers were immobilized on the gold surface of piezoelectric quartz crystal biosensor with biotin-avidin method. The reaction between anti-IgE aptamers and IgE was monitored in time on piezoelectric sensor. We tried to regenerate the sensor surface after binding IgE by rinsing the aptamer-coated chips with HCl, NaOH, EDTA, urea and formamide individually. Aptamer-coated chips were stored in PBS with 0.1% sodium azide and the stored chips were used to detect IgE in 35 days. RESULTS Of the five reagents, EDTA was the best one for regeneration of aptamer-coated chips and the sensor could retain 91.5% of the original detecting signals after five regeneration cycles. Moreover, the aptamer-coated chips could be stored in the binding buffer for 21 days without obvious loss of activity. CONCLUSIONS Compared with antibody-based piezoelectric sensor, aptamer-based sensor has lower cost, more regeneration cycles and longer time for the storage of chips. This series of experiments shows the superiority of aptamer detection.

OBJECTIVE To investigate the change in antimicrobial resistance to Pseudomonas aeruginosa in our hospital from Jan 2005 to Dec 2006 and direct the using of drugs reasonably. METHODS P. aeruginosa was identified by API and VITEK2 system, and its antimicrobial resistance was determined by Kirby-Bauer method and VITEK2 system. The antimicrobial resistance rates were analyzed by WHONET5.4 software. RESULTS The resistant rates of P. aeruginosa to SAM, CTX, and CRO were higher than 70%. The resistant rate to CIP was the lowest (about 30% or so). CONCLUSIONS P. aeruginosa is still a major pathogenic bacterium in our hospital. It is very important to select antibiotics correctly according to the results of susceptibility tests.

OBJECTIVE To establish an aptamer-based piezoelectric sensor assay to detect human immunoglobulin E (IgE) and acquire the parameters about this kind of biosensor. METHODS Anti-IgE aptamers were immobilized on the gold surface of piezoelectric quartz crystal sensor with biotin-avidin method. The reaction between anti-IgE aptamers and IgE was monitored in time on piezoelectric sensor. Different concentrations of IgE were detected and the calibration curve of IgE was drawn. Non-specific response signals of BSA, IgG and IgE were monitored to show the detecting specificity of aptamer-based sensor. RESULTS For the aptamer-based sensor, the lowest limit of detection was 0.055mg/L and the linear range was 0.1-2.5mg/L. Non-specific signals of this sensor were less than 5% of specific signals of IgE at the same concentration. CONCLUSIONS The aptamer-based piezoelectric sensor can detect 5.5 ng IgE while the non-specific signals are very low. So this aptamer-based sensor is hopeful to be applied to clinical laboratory diagnosis.

OBJECTIVE To analyze the major reasons of wound infection after external fixator application and then introduce management measures to prevent following wound infections. METHODS Totally 542 patients adopting external fixators between May 2005 and May 2007 were retrospectively reviewed. All the external fixator-related infections were inspected and the excretions from these infected wounds were collected to perform bacterial culturing. RESULTS The total infection rate of these 542 patients after external fixator application was 2.77%. Among them, six were infected with the bacteria in distraction osteogenesis group and the infection rate was 8.82%; three were infected in bone un-union and bone defect group and the infection rate was 5.36%; whilest the common fracture-fixing group got the lowest infection rate of 0.39%. CONCLUSIONS Wire-crossing positions are the most frequently infected sites after external fixation and the drug-resisted bacteria are the most commonly detected pathogens. Thus, increasing the stability of fixators, enhancing the infection supervision of operation environment, draining the wound thoroughly and using antibiotics rationally are the most effective managing measures to prevent external fixator-related infections in orthopedics.
