Objective To evaluate the efficacy of jaw thrust device in the upper airway obstruction. Methods Thirty-five ASA Ⅰ or Ⅱ patients aged 18-64 yr with body mass index < 30 kg/m~2 undergoing elective surgery under general anesthesia were included in this study. The anesthesia face mask was placed and held tightly by 4 straps of JTD and connected to the anesthesia machine. Anesthesia was induced with midazolam, propefol, fentanyl and atracurium. When muscle relaxation was achieved, tracheal intubation was not performed. The airway obstruction was assessed by airway peak pressure and stridor score (breathing sounds detected by auscultation over the trachea). And then tracheal intubation was performed, and the patients were mechanically ventilated. Results There was no significant difference in airway pressure and stridor scores between JTD and jaw thrust maneuver. Conclusion JTD can effectively lift the jaw and improve the upper airway obstruction.

Objective To explore the adverse effects of formaldehyde(FA)on learning and memory ability of mice and the antagonistic effect of N-acetyl-cysteine(NAC),an antioxidant.Methods Thirty-four ICR mice were randomly divided into four groups,the control(NS,n=8),treated with FA(15 mg/kg,n=9),treated with NAC(100 mg/kg,n=8),treated with FA(15 mg/kg) plus NAC(100 mg/kg,n=9),the treatment was conducted by intraperitoneal injection once a day for seven consecutive days.On the eighth day,the learning and memory ability were tested by using water labyrinth task for seven consecutive days.Results The mice in FA group behaved excited,restless and then turned to repose,moveless and clustering,but this phenomena was not seen in the other groups.There was no significant difference in the body weight of mice among groups.As for learning,latent period in the FA group [(27.15?2.66)s] was significantly longer than that in the control group [(15.83?2.82)s] and the FA+ NAC group[(14.98?2.66)s],and revealed statistical significance(P

ObjectiveTo observe the pathogenic relationship and the mechanisms between the first molars and the temporomandibular disorders(TMD) by getting epidemiology data.MethodsThe oral examinational people during 2007 to 2011 as investigating objects were selected and epidemiological study was carried out with standard clinical diagnostic criteria for dental caries TMD.ResultsThe people with dysfunctional first molars showed that TMD positive rate was 51.48％,and normal molars was 23.47％.The results had significant difference( x2 =54.34,P ＜ 0.01 ).ConclusionThe people with dvsfunction of first molars mav be liable to TMD.

Objective: To establish a radioresistant model of non-small-cell cancer A549, and to provide the experimental basis for further researchonradioresistance. Methods: The cell number and the dose of radiation therapy were confirmed. The intermittent radiation were used to induce the radioresistant cell model. The morphology of cells were observed with an inverted phase contrast microscope. Colony formation was used to identify the radioresistance of the RA549 cell. Results: RA549 cells were longer and bigger than A549 cells; surviving fraction of RA549 was significantly increased than A549. Conclusion: Intermittent radiation can successfully induce the radioresistant cell model of lung cancer cells.
