芬太尼抑制七氟醚复合瑞芬太尼麻醉恢复期间患儿躁动的药效学

Oblective To define the median effective dose (ED50) and 95%effective dose of fentanyl for inhibition of emergence agitation after sevoflurane-remifentanil anesthesia in children.Methods Twenty six ASA ⅠorⅡchildren aged 5-8 yr weighing 15-30 kg undergoing adenoidectomy under general anesthesia were studied.The patients were unpremedicated.Anesthesia was induced with inhalation of 8%sevoflurane (fresh gas flow=6 L/min)and iv remifentanil 1μg/kg.The patients were mechanically ventilated after tracheal intubation.Fentanyl was injected iv to inhibit emergence agitation.The dose of fentanyl was determined by using modified Dixon's upand-down method (increment or decrement of 0.5μg/kg).The initial dose of fentanyl was 4 μg/kg.Anesthesia Sevoflurane inhalation and remifentanil infusion were terminated at the end of operation.The patients were transferred to the PACU.No alteration in the ventilatory settings was made.Stimulation of the patients was avoided during emergence.The emergence time and the occurrence of agitation,nausea and vomiting and respiratory depression within 4h after operation were recorded.ED50,ED95 and 95%confidence interval (CI) of fentanyl for inhibition of emergence agitation were calculated.Results ED50 was 3.01μg/kg (95%CI 2.52-3.40μg/kg) and ED95 3.81μg/kg(95%CI 3.41-6.22μg/kg).No nsusea and vomiting and respiratory depression occurred within 4h after operation.The emergence time was (11.3±2.6) min.Conclusion The ED50 and ED95 of fentanyl for inhibition of emergence agitation after sevoflurane-remifentanyl anesthesia were 3.01 and 3.81μg/kg respectively in children.     

神经梅毒四例临床分析

近年来,梅毒发病率在我国呈上升趋势,1991—2006年全国共报道梅毒病例75万余例,年平均发病率约3．72／10万,总体呈现上升趋势。神经梅毒为苍白密螺旋体感染人体后出现大脑、脑膜或脊髓损害的一组临床综合征,是Ⅲ期梅毒全身性损害的重要表现。本文回顾分析2009—2010年徐州医学院附属医院神经内科住院治疗的4例神经梅毒患者的临床诊断与治疗过程,旨在提高临床医师对该病的诊断和治疗水平。     

RhoA蛋白参与凝血酶对胎鼠大脑皮层神经元的损伤

目的 探讨凝血酶诱导的胎鼠大脑皮层神经元损伤与RhoA蛋白活化表达的关系.方法 体外培养胎鼠大脑皮层神经元8d后,采用Western blotting检测不同浓度凝血酶(0、1、10、30和100 U/mL)作用3h后及30 U/mL凝血酶作用不同时间(0、0.5、1、3和6h)对皮层神经元RhoA蛋白活化表达的影响;RhoA蛋白活化抑制剂Exoenzyme C3预处理0.5 h及30 U/mL凝血酶作用皮层神经元3h后,行Western blotting检测RhoA蛋白活化表达的情况,并采用Hoechst33258核染色及CCK-8法观察Exoenzyme C3预处理和未处理时凝血酶对皮层神经元的损伤情况. 结果 在浓度实验中,30 U/mL凝血酶作用皮层神经元3h后能明显增加RhoA膜蛋白表达,与0U/mL组相比差异有统计学意义(P＜0.05);而各浓度凝血酶对RhoA总蛋白表达无明显影响.在时程实验中,与其他时间点相比,30 U/mL凝血酶在3h时能明显增加RhoA膜蛋白表达,差异有统计学意义(P＜0.05),但对RhoA总蛋白表达也无明显影响.在Exoenzyme C3干预实验中,Exoenzyme C3预处理组与凝血酶组相比,RhoA膜蛋白表达明显降低,差异有统计学意义(P＜0.05);Hoechst3258核染色显示,与凝血酶组相比,Exoenzyme C3预处理组中核浓染细胞数量明显降低,差异有统计学意义(P＜0.05);CCK-8法检测细胞活性显示,凝血酶组细胞存活率明显低于Exoenzyme C3预处理组,差异有统计学意义(P＜0.05). 结论 凝血酶诱导的胎鼠大脑皮层神经元损伤与RhoA膜蛋白的高表达即RhoA蛋白活化表达有关.
