Objective To investigate the effects of different tidal volume mechanical ventilation on pulmonary function and inflammatory factors in gynecologic laparoscopic surgery.Methods 45 patients undergoing gynecological laparoscopic surgery without lung disease,ASA Ⅰ-Ⅱ,aged 20-45 years old,weight 45-65 kg,operation time 2-3 hours,were randomly divided into A,B,C three groups,15 cases in each group.Mechanical ventilation with different tidal volume of the three groups,A group,B group and C group were 8mL/kg,9mL/kg,10mL/kg.Blood gas analysis was performed before anesthesia (T0),30 minutes (T1),(T2),PA-aDO2 (60 minutes) (T3),and 120 min (T4),respectively,and the peak airway pressure and mean pressure were recorded.IL-6,TNF-α and IL-10 levels in plasma by radial artery blood sampling were simnultaneously determined.Results Comnpared with A group,the concentrations of Ppeak and Pmean were increased in B group at T1-T4 (t =5.13,4.78,6.54,5.32 and t =7.54,4.88,5.37,4.95;all P < 0.05),the concentration of Ppeak and Pmean in C group at T1-T4 increased (t =7.76,8.87,7.23,8.99 and t =6.42,7.38,7.62,9.86;all P < 0.05).Compared with B group,the concentrations of Ppeak and Pmean were increased in C group at T1-T4 (t =4.76,5.87,4.23,3.99 and t =4.76,3.99,6.06,4.52;all P < 0.05).Compared with A group,the A-aDO2 values of B group and C group were increased at T1,T2,T3 and T4 (t =5.32,5.48,4.88,5.69 and t =7.85,7.32,8.45,6.67;all P < 0.05).Compared with B group at the same time point,the A-aDO2 value of C group increased at four times of T1-T4 (t =5.62,4.38,6.94,4.22,P <0.05).Compared with group A,the concentration of A-aDO2 in C group was higher than that in B group at the same time point (t =4.45,4.87,5.32,4.79 and t =7.68,7.59,7.44,8.38;all P < 0.05).The levels of IL-6 and TNF-α in C group were significantly higher than those in the control group (t =4.78,5.56,7.62,8.03 and t =3.98,4.52,5.46,6.23;all P < 0.05).Compared with T0,IL-6 and TNF-α concentrations AT T2-T4 in A group had no statistically significant differences (all P > 0.05).Compared with B group,the levels of IL-6 and TNF-α in C group were significantly higher (t =4.58,4.99,6.53,4.77 and t =5.62,7.89,6.43,4.52;all P < 0.05).Compared with T0,IL-6 and TNF-α concentrations at T2-T4 in A group had no statistically significant differences (all P >0.05).There was no significant difference in IL-10 concentration among the thrce groups.Conclusion Laparoscopic surgery according to the end tidal carbon dioxide partial pressure (PetCO2) ventilation frequency,8 mL/kg tidal volume mechanical ventilation has no effect on the IL-6,TNF-alpha,IL-10 and other inflammatory factors,mechanical ventilation tidal volume is more appropriate.

Objective To explore the application of case-based discussion combined with translational medicine teaching method in clinical teaching of gastrointestinal surgery.Methods Totally 100 undergraduates of clinical medicine in grade 2007 and 100 undergraduates in grade 2008 from the second military medical university were divided into experimental class (50 students,25 in discussion class and 25 in comprehensive class) and control class (50 students).Method of case-based discussion was applied in discussion class; method of case-based discussion combined with translational medicine was employed in comprehensive class and traditional method was used in control class.Results Scores in experimental class were superior to those in control class ; questionnaire survey showed that 90% students thought the new model was better than the traditional model; the interests of students in exploring clinical problem in experimental class were increased (90% vs.50% ) ;the sense of mission and responsibility was Strengthened (86% vs.64% ) ;the scientific research thinking was more active (80% vs.48% ) ; the individual ability and quality were enhanced (76% vs.50% ),the depth and width of study were markedly increased (80% vs.52% ),the consciousness of independent study and thinking was strengthened (88% vs.54% ).Comprehensive class had more obvious improvements in scientific research thinking,individual ability and quality,depth and width of study,independent study and thinking.Conclusions The new teaching model which combined translational medicine with case discussion breaks through the traditional model and adapts to the requirements of modem medicine,it can enhance the teaching effect and worth promoting in educational reform.

Objective To discuss the influence of Open resetlogs on Oracle database recovery. Methods Database backup was used to recover database before resetlogs. Before Oracle 9i, Oracle database was recovered through two steps; after Oracle10g, Oracle archived redo log by new format. Results Both methods could recover Oracle database by using backups before resetlogs. Conclusion Before Oracle9i, the recovery steps are complex, so it is suggested a consistent database backup should be made after resetlogs. By using the new archived redo log format after Oracle10g, it is easy to recover database through resetlogs.

AIM: To optimize the best prescription of micro-emulsions of volatile oil in rhubarb of compound liquid spray by triangular phase diagram METHODS : Poloxamer-108 was used as emulsifiers,absolute alcohol as assistant emulsifiers,volatile oil from Lonicera dasystyla and Curcuma longa as the oil phase,the proportion between the emulsifier and append-emulsifier was established RESULTS : Optimized ratio of Poloxamer-108 and alcohol was 1∶10,the volatile oil in prescription formed micro-emulsions,distributing stably in the spray CONCLUSION : The study of micro-emulsions of volatile oil in compound liquid preparation of traditional Chinese medicine by triangular phase diagram offered a short-cut for resolving its stability. The experiment also suggested that the micro-emulsions could increase solubility of insoluble volatile oil from TCM.

qualitative and quantitative analysis of solid depolymerization products for supercritical methanolysis of ploy(ethylene terephthalate) polyester (PET) were studied by means of reversedphase high performance liquid chromatogr aphy on ZorbaxC8(4.6mm×250mm) with 70%(V/V) methanol as mobile phase. The results showed that the solid depolymerization products were mainly composed of dimethyl terephthalate (DMT), methyl(2hydroxyethyl)terephthalate (MHET), bis(hydroxyethyl)tere phthalate (BHET), dimers and oligomers, which could be separated effectively under the above chromatographic conditions. The calibration curves of DMT and BHET were linear in the range of 1.0~45 mg/L (n=8),r=0.9998~1.0000 and RSD<2.8%. The determination limits of DMT and BHET were 4.0×10-4μg and 6.0×10-4μg respectively.
