简介：目的探讨白黎芦醇（RE）对垂体腺瘤GH3细胞增殖和泌乳素（PRL）合成分泌的影响，及其与雌激素受体（ERs）的关系。方法RE作用于GH3细胞．用免疫荧光法和Western印迹法测定ERs的表达情况．分别用ELISA法和Western印迹法测定培养基内和细胞内PRL水平，用MTT法测定细胞增殖，同时观察了雌二醇（E2）和特异性雌激素受体激动剂对RE的拮抗作用。结果RE改变ERs表达水平，减少PRL合成分泌，抑制GH3细胞增殖，E2和特异性雌激素受体激动剂对RE有拮抗作用。结论RE通过ERs抑制PRL合成、分泌及细胞增殖，从而发挥抗肿瘤作用，两种效应的信号转导途径不尽相同。

简介：目的：探究温阳解郁汤联合针灸对阳虚肝郁型失眠老年患者睡眠及不良情绪的影响。方法：选取阳虚肝郁型失眠老年患者120例,按随机数表法分为对照组和观察组,各60例。对照组给予针灸治疗,观察组在对照组基础上给予温阳解郁汤治疗,10d为1个疗程,2组均连续治疗4个疗程。采用PSQI评分评估2组患者治疗前后睡眠质量,另采用HAMA及其HAMD评分评估2组治疗前后不良情绪改善情况。结果：与治疗前比较,治疗后2组PSQI评分均显著降低（P〈0.01）,且观察组均显著低于对照组（P〈0.01）;与治疗前比较,治疗后观察组患者HAMA、HAMD评分显著降低,且观察组显著低于对照组（P〈0.01）。结论：温阳解郁汤联合针灸治疗阳虚肝郁型老年患者可有效提高其睡眠质量,改善患者不良情绪。
