目的 基于DNA条形码技术建立人参与西洋参种子的分子鉴别方法。方法 采用生药鉴定方法研究其性状、显微特征，并结合DNA条形码技术，基于中药材DNA条形码数据库，通过ITS2序列比对、遗传距离比较和构建临接（NJ）系统发育树，对人参与西洋参的种子进行鉴别研究。结果 人参与西洋参种子的种内遗传距离分别小于种间遗传距离，系统发育树图中各物种均聚为一支，来自9个产地的42份人参及西洋参的种子均为正品，且容...
分析来士普联合认知行为治疗对脑卒中后抑郁(PSD)的疗效。收集200例PSD患者并随机分为空白对照组,对照组1,对照组2及观察组。空白对照组不进行任何治疗,对照组1实施认知行为治疗,对照组2实施来士普治疗,观察组在对照组2用药基础上进行认知行为治疗。四组患者分别与治疗前24 h及治疗12周后进行汉密顿抑郁量表(HAMD)、神经功能缺损程度量表(NIHSS)和改良Banhel指数(MBI)评分。治疗...
分别采用浸渍法和药膜法测定了辛硫磷对枸杞木虱不同发育期若虫和成虫的毒力，同时测定了辛硫磷对不同龄期枸杞木虱羧酸酯酶（CarE）活性的抑制作用及酶的动力学常数。结果表明：辛硫磷对枸杞木虱的LC50值随若虫龄期的增大而升高，至成虫期再相对降低，其对5龄若虫的LC50值为0.995 mg/L，是对1龄若虫LC50值（0.047 mg/L）的21.2倍。辛硫磷对不同龄期枸杞木虱羧酸酯酶活性的抑制作用I50...
为明确氟唑菌酰胺和吡唑醚菌酯在芒果上的残留行为，于2012和2013年在中国广东省和广西自治区进行了氟唑菌酰胺和吡唑醚菌酯在芒果上的田间残留及消解动态试验，建立了芒果中氟唑菌酰胺及吡唑醚菌酯残留量的高效液相色谱检测方法。样品用丙酮提取，乙酸乙酯液-液分配萃取，弗罗里硅土柱层析净化，高效液相色谱-二级管阵列紫外检测器检测，外标法定量。结果表明：氟唑菌酰胺和吡唑醚菌酯在芒果上的消解半衰期分别为7.2～...
