About 5rag powder lunar rock sample, without any eanduetive material mixed in it, was pressed on the surface of T type electrode. A single exposure was made under the optimum condition After development,the relative sensitivity, coefficients are calculated on the basis of the single exposure by U.S. Geological Survey Standard Rock AGV-1. More than 20 elements be be determined by this technique with a typical precision of ± 20%.展开更多
目的评价阿替普酶静脉溶栓的疗效及安全性,并分析影响患者预后的因素。方法回顾性分析进行重组组织型纤溶酶原激活剂静脉溶栓的89例急性脑梗死患者的临床资料,分析影响阿替普酶静脉溶栓疗效及安全性的因素。结果溶栓后当时神经功能良好...目的评价阿替普酶静脉溶栓的疗效及安全性,并分析影响患者预后的因素。方法回顾性分析进行重组组织型纤溶酶原激活剂静脉溶栓的89例急性脑梗死患者的临床资料,分析影响阿替普酶静脉溶栓疗效及安全性的因素。结果溶栓后当时神经功能良好者47例(52.81%),7d时神经功能恢复良好者56例(62.92%)。预后良好组年龄低于预后不良组,溶栓前美国国立卫生研究院卒中量表(National Institute of Health Stroke Scale,NIHSS)评分显著低于预后不良组,溶栓距发病时间短于预后不良组(P<0.05)。出血组溶栓前NIHSS评分高于未出血组,溶栓距发病时间长于未出血组,心房颤动发生率高于未出血组。结论应用阿替普酶静脉溶栓治疗急性脑梗死患者是安全有效的,且年龄越低、溶栓前NIHSS评分越低、溶栓距发病时间越短,3个月预后越好;另外,溶栓前NIHSS评分、溶栓距发病时间和心房颤动病史是影响溶栓后出血的几大危险因素,但颅内出血并不影响3个月预后。展开更多
目的探讨机械碎栓联合动静脉多途径溶栓术治疗超早期后循环脑梗死的安全性和有效性。方法回顾性分析发病6h内的后循环脑梗死患者22例,行机械碎栓联合动静脉多途径溶栓术,即静脉尿激酶溶栓后行微导管、微导丝机械碎栓联合动脉内注射尿激...目的探讨机械碎栓联合动静脉多途径溶栓术治疗超早期后循环脑梗死的安全性和有效性。方法回顾性分析发病6h内的后循环脑梗死患者22例,行机械碎栓联合动静脉多途径溶栓术,即静脉尿激酶溶栓后行微导管、微导丝机械碎栓联合动脉内注射尿激酶溶栓治疗。结果 22例患者完全再通13例(59.1%),部分再通5例(22.7%),未开通4例(18.2%),总开通率为81.8%;继发出血2例(9.1%),死亡2例(9.1%)。术后脑梗死溶栓分级(modified thrombolysis in cerebral infarction,mTICI)靶血流可达2b^3级,术后美国国立卫生研究院卒中量表(National Institute of Health Stroke Scale,NIHSS)评分逐渐降低,日常生活能力量表(Activity of Daily Living Scale,ADL)评分逐渐升高(P<0.01)。出院6个月时残障程度与出院时比较差异无统计学意义(P>0.05)。结论对超早期治疗时间窗的后循环脑梗死患者行机械碎栓联合动静脉多途径溶栓术是安全有效的。展开更多
