Methods: Forty patients who received selective abdominal surgery with general anesthesia for 3-4 hrs and ASA grade Ⅰ-Ⅱ were divided into two groups, the trial group and the control group, 20 patients in each group. After being sent into the postanesthesia care unit (PACU), the trial group was treated with intravenous dripping of SFI 1.0 ml/kg and the control group was treated with intravenous dripping of equal volume of normal saline. All patients were observed in double blindly manner, the self ventilation recovery time, extubation time, the time of leaving PACU and their Glasgow coma scale (GCS) were recorded and compared. 2 ml of peripheral venous blood were taken to determine the plasma β-endorphin (β-EP) content at the time points of before (T1), 5min (T2), 15min (T3) and 30 min (T4) after dripping. Results: The self ventilation recovery time, extubation time and time of leaving PACU in the trial group were all shorter than those in the control group (P<0 01), the GCS in the trial group was better than that in the control group (P<0 01). The plasma content of β-EP raised gradually along the recovering of patients consciousness, as compared with the content before dripping (T1), it showed insignificant difference at time point T2 but significant difference at T3 and T4, comparison at the corres ponding time point showed that the content at T1 and T2 were similar in the two groups (P>0 05), but at T3 and T4, the content was higher in the trial group than that in the control group respectively (P<0 01). There was insignificant difference between T1 and before treatment ( P>0 05), but significant difference was found when compared T3, T4 and before treatment (P<0 01).Conclusion: SFI could accelerate the resuscitation after general anesthesia, the mechanism may be related with its action in raising plasma β-EP level.展开更多

Three zones are generated： the ablation zone that presented molten morphology and was composed by the Si and C phase; the condensation zone formed by vaporized SiC; and the oxidation zone that showed the characteristics of thermal oxidation. The ablation depth and oxidation range increase linearly with fluence and pulses within 0.5-4 J/cm2, but the normalized ablation efficiency is constant （3.60± 0.60 μm · mm2/J）. The theoretical photochemical ablation depth supplies 25% of the total depth at 1 J/cm2 but decreases to 16% at 4 J/cm2. The ablation is dominated by the photothermal effect and conforms to the thermal evaporation mechanism.展开更多
