Objective To explore the effect iveness and safety of ProSeal laryngeal mask(PLMA)used in posterior spinal surgery. Methods Forty ASA Ⅰ - Ⅱ patients of thoracic-lumbar fracture were randomly divided into PLMA group and tracheal intubation (TI) group by systematic sampling with 20 cases each. PLMA or TI was inserted after intravenous anesthesia induction. The number of intubation, intubation time and time to surgery were recorded, systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were recorded induction (To), during intubation (T1), at 1 min (T2),3 min(T3), 5 min (T4), 10 min after intubation (T5), during extubation (T6). The intubation, extubation, and the maintain ventilation process of the respiratory and respiratory damage were recorded. Results All patients in PLMA group and TI group achieved satisfactory lung ventilation at the first attempt. There were no significant difference in the number of intubation, intubation time and time to surgery between two groups (P ＞ 0.05 ).SBP,DBP,HR at T1,T2,T3,T6 in TI group were significandy higher than To and those in PLMA group (P＜0.05). The intubation, extubation, and the maintain ventilation process of the respiratory and respiratory damage in TI group (5,25,36 cases) were more than those in PLMA group (0,1,6 cases)(P ＜0.05).Conclusion PLMA for posterior spinal surgery is safe and effective.

Abstract Benzo [a] pyrene ( B [a] P ) is a well-recognized environmental pollutant. Exposure to B[a]P elicits many adverse biological effects, including tumorigenesis, immunosuppression, teratogenicity, and hormonal effects. In addition to B [a] P exposure-induced genetic damages, a growing number of studies demonstrate that epigenetic changes play an important role in chemically induced carcinogenesis. In order to provide better understanding of epigenetic changes of B [a] P and their potential association with genotoxic endpoints, this review summarizes the advances in the applications of functional genomics in the research of B [a] P toxicity, including functional genomics techniques, regulation of human genome expression, DNA sequence variability, model organisms research, and bioinformatics studies, so as to provide insights into the management of B [a] P exposure-induced health injuries and use of genomics techniques to unravel the mechanisms underlying the toxicity of other environmental pollutants.

Objective To measure the magnitude of galvanic currents produced by different occluding metallic contact.Methods The circuits of instantly different metallic contact were simulated in artificial saliva,and electrical potential of every couple and 15 currents of instant contact were measured.To simulate night sleep,after 8 h soaking,15 currents were obtained in addition.Results During early soaking,gold/Co-Cr alloy produced the highest current(6.17 ?A),while there were significant differences in currents between gold/zinc-free amalgam,gold /zinc-containing amalgam and other couples(P0.05),and the current value was low all the time.Potential of zinc-containing amalgam was more negative than other alloys,and it was always under anodic behavior during the experiment and was corrupted acceleratedly.Conclusion Couples of gold/titatium,gold/zinc-containing amalgam,zinc-free/zinc-containing amalgam appearing in oral will do harm to the patients′health,while Co-Cr/zinc-free amalgam can coexist in oral.Corrosion behavior of amalgam is affected by different contents of zinc.

OBJECTIVE To investigate the distribution and antibacterial resistance of nosocomial infection from a new hospital pathogens,and provide reference for clinical rational use of drugs.METHODS Statistical methods were used to analyze the data of pathogen′s formation,distribution and antibacterial resistance of a new hospital.RESULTS A total of 1852 clinical isolates were collected from Mar 2005 through Mar 2007,of which Gram-negative microorganisms and Gram-positive cocci accounted for 71.0 % and 29.0%,respectively.The most commonly encountered pathogens were Pseudomonas aeruginosa,Escherichia coli,Klebsiella spp,Acinetobacter,Staphylococcus aureus and coagulase-negative Staphylococcus.Except Acinetobacter,up to 6% strains of Gram-negative microorganisms were resistant to the imipenem,meropenem and piperacillin/tazobactam;Gram-positive cocci were still highly sensitive to vancomycin and teicoplanin.CONCLUSIONS A new hospital is similar with other hospitals in the data of formation,distribution and antibacterial resistance of nosocomial infection pathogens.

Hypoxia-inducibIe factor-1(HIF-1)is a main nucIear transcription factor for response to intratumor hypoxia. RecentIy,it has become a hot spot to attempt to improve hypoxia by inhibiting HIF-1. HIF-1 inhibitors' mechanisms of action are wide,which infIuences the two signaI transduction pathways that are phosphatidyIinositoI-3-kinase/ protein kinase B/ mammaIian target of rapamycin and Ras/ Raf/ mitogen-activated protein kinase kinase1-2/ extraceIIuIar signaI-reguIated kinase1-2,inhibits the function of heat shock protein 90,and reduces transcriptionaI activity of HIF-1. In combination with radiation,HIF-1 inhibi-tors significantIy enhance radiosensitivity and weaken radioresistance of hypoxia ceIIs,which contributes to the therapeutic effect of tumor irradiation.
