Objective Comparing the effect of different anesthetic inductions in pediatric pa-tients undergoing bronchial foreign body removal.Methods Thirty pediatric patients,aged 9-58 months,undergoing emergency bronchial foreign body removal,were randomly into 3 groups (n=10 each):group sevoflurane (group S),group propofol (group P),and group ketamine (group K).Pa-tients in group S were inducted with sevoflurane 8% inhalation,group P with propofol 2.5 mg/kg in-travenous injection,group K with ketamine 5 mg/kg intramuscular injection.Three groups of pa-tients breathed spontaneously during operative period and received topical anesthesia of lidocaine be-fore the placement of rigid bronchoscopy.Combination of intravenous target-controlled infusion of propofol (target plasma concentration of 3-3.5 μg/ml)and remifentanil (target plasma concentration of 2-3 ng/ml)was used for maintenance of anesthesia.The rigid bronchoscopy was inserted after pre-oxygenation for 3 min.Rigid bronchoscopy was performed and the placement time,the first place-ment successfully rate,hypoxemia and side effects as well as postoperative awaking time were recor-ded.Results The first placement successfully rate,group S 90%,group P 70%,group K 40%,with significant difference among three groups (P<0.05).The incidence of side effects were not signifi-cant difference in three groups;In group S and group P,the placement time and the anesthesia awa-king time was significant shorter than that in group K (P<0.05).Conclusion Compared with propo-fol intravenous induction and ketamine intramuscular induction,the high concentration sevoflurane in-duction can provide faster induction,shorter waking time,and reduceside effects in childen undergo-ing bronchial foreign body removal.

OBJECTIVE: To analyze postmortem chemical changes in Landrace costal cartilages and ribs using attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy, and to provide a novel technique for estimation of postmortem interval (PMI). METHODS: The swines were sacrificed by hemorrhage and their costal cartilages and ribs were kept in 20 degrees C. The chemical analysis of the costal cartilages and ribs were performed using ATR-FTIR every 72 h. The correlation between the certain spectral parameters and PMI was also analyzed. The time-dependent changes of costal cartilages were more significant than ribs. RESULTS: There were no obvious changes for the main absorbance bands position, and some absorbance band ratios showed time-dependent changes and significant correlations with the PMI. CONCLUSION ATR-FTIR has the ability to analyze postmortem chemical changes of the swine costal cartilages and ribs, and it can be a new method to estimate PMI based on spectroscopy.

The aim of this study was to explore the mechanism underlying the blast crisis of chronic myeloid leukemia. Analysis of gene expression profiles of chronic myeloid leukemia patients in chronic phase and blast crisis were analyzed by using cDNA microarray representing 4096 genes for finding the differential expression genes. The results indicated that 74 differential expression genes were identified in at least 3 gene chips in blast crisis compared with chronic phase, among them 52 genes were down-regulated and 22 genes were up-regulated in blast crisis. The differential expression genes were involved in these genes including genes related to cell structure/mobility, signal transduction, transcription factor, related immunity, metabolism, cell cycle, oncogene/anti-oncogene, cell receptor, protein translation/synthesis and some unknown functions. It is concluded that the blast crisis of CML is resulted from abnormality and interaction of multigene, among them functional abnormal genes related to signal transduction, cell cycle, cell differentiation and immunity may be the critical genes for chronic myeloid leukemia blast crisis.
