简介:客观:为了改进倔强的脸中部的外部T房间non-Hodgkin鈥檚的功效,有L天门冬氨酰胺酶(LASP)的淋巴瘤(MPTC-NHL)基于抢救化疗。方法:有倔强的MPTC-NHL的21个病人被分析,11patients(LASP组)收到了L天门冬氨酰胺酶基于的抢救化疗由L天门冬氨酰胺酶,长春新碱和dexame-thosone组成。没有L天门冬氨酰胺酶,10个病人(控制组)收到了抢救联合化疗。结果:完全的宽恕率为LASP组是45.6%,0.0%为控制组织(P<0.05)。全面反应率(CR+PR)为LASP组是63.6%,10.0%为控制组织,分别地(P<0.05)。2年的幸存率为LASP组是45.5%,0.0%为控制组织(P<0.05)。LASP的主要不利效果是白细胞减少,浆液bilirubin和多糖症的举起。结论:LASP基于的初步的临床的学习表演抢救化疗可以与倔强的MPTC-NHL改进反应率和病人的2年的幸存率。进一步继续学习是必要的。
简介:摘要目的比较S-ReSC和S.T.O.N.E.评分系统对经皮肾镜取石术后结石清除率的预测价值。方法收集2016年9月至2019年4月在本院接受F24标准通道经皮肾镜取石术治疗的113例结石患者的临床资料,根据术后结石是否清除分为结石清除组82例和结石残留组31例。根据S-ReSC和S.T.O.N.E.评分系统分别对患者进行S-ReSC和S.T.O.N.E.评分,采用受试者工作特征(ROC)曲线分析S-ReSC和S.T.O.N.E.评分系统对结石清除的预测价值,采用多因素logistic回归模型分析影响结石清除的因素。结果结石清除组手术时间、术中出血量和住院时间均低于结石残留组(t=2.325、2.726、2.301,P<0.05);结石清除组S-ReSC评分和S.T.O.N.E.总评分低于结石残留组(t=10.673、5.147,P<0.05),两组S.T.O.N.E.评分中结石最大截面积、皮肾通道距离、肾积水程度、累及肾盏个数四项评分分布比较,差异有统计学意义(χ2=9.296、4.543、4.292、8.533,P<0.05),两组结石密度评分比较,差异无统计学意义(χ2=2.105,P>0.05);S-ReSC评分、S.T.O.N.E.总评分、结石最大截面积、肾积水程度、累及肾盏个数与结石清除状态有相关性(P<0.05),而皮肾通道距离、结石密度与结石清除状态无相关性(P>0.05);S-ReSC评分、S.T.O.N.E.评分预测结石清除的ROC曲线下面积(AUC)分别为0.875(95%CI:0.796~0.953)、0.751(95%CI:0.655~0.847),S-ReSC评分预测结石清除的AUC大于S.T.O.N.E.评分(Z=2.117,P=0.034);多因素logistic回归分析显示,手术时间、S-ReSC评分和S.T.O.N.E.评分是结石清除的影响因素。结论S-ReSC和S.T.O.N.E.评分系统均是预测经皮肾镜取石术后结石清除率的有效方法,S-ReSC评分的预测准确性更好。
