目的:观察百合知母汤对肾阴虚型围绝经期综合征大鼠子宫系数、血清性激素水平及下丘脑ER m RNA的表达情况的影响。方法:选用双侧卵巢切除的雌性3月龄SD大鼠,随机分为12组:模型组,雌激素组,百合知母汤水煎液组,黄酮高、低剂量组,皂苷高...目的:观察百合知母汤对肾阴虚型围绝经期综合征大鼠子宫系数、血清性激素水平及下丘脑ER m RNA的表达情况的影响。方法:选用双侧卵巢切除的雌性3月龄SD大鼠,随机分为12组:模型组,雌激素组,百合知母汤水煎液组,黄酮高、低剂量组,皂苷高、低剂量组,黄酮皂苷配比Ⅰ、Ⅱ、Ⅲ、Ⅳ组及空白对照组。采用甲状腺素复制肾阴虚模型,同时各组给予相应药液。4周后测定大鼠子宫系数,血清中雌二醇(E2)、孕酮(P)、促卵泡生成激素(FSH)及促黄体生成激素(LH)的含量,下丘脑ER m RNA的表达情况。结果:与空白对照组比较:模型组大鼠的子宫系数明显降低,E2、P水平明显降低,FSH、LH升高,下丘脑内ER m RNA表达减少(P<0.01)。与模型组比较,各给药组大鼠的子宫系数明显升高,E2、P水平升高、FSH、LH水平则有所下降,下丘脑ER m RNA表达升高,且水煎液组、黄酮皂苷配比Ⅲ和Ⅳ组作用更为显著(P<0.05,P<0.01)。结论:百合知母汤能明显改善围绝经期综合征大鼠的肾阴虚症状,且黄酮和皂苷有效部位合用效果好。展开更多
目的通过检测同一宫颈上皮内癌变或宫颈癌疑似病例宫颈石蜡包埋样本及脱落细胞中HPV E6/E7 m RNA的水平,分析两种检测结果的差异,探讨二者在宫颈癌筛查的应用价值。方法对302例宫颈上皮内癌变或宫颈癌疑似病例分别取宫颈活检组织及脱落...目的通过检测同一宫颈上皮内癌变或宫颈癌疑似病例宫颈石蜡包埋样本及脱落细胞中HPV E6/E7 m RNA的水平,分析两种检测结果的差异,探讨二者在宫颈癌筛查的应用价值。方法对302例宫颈上皮内癌变或宫颈癌疑似病例分别取宫颈活检组织及脱落细胞,两类标本均采用b DNA技术进行HPV E6/E7 m RNA检测,同时行病理学检查,并对检测的阳性率及灵敏度、特异度做出统计学分析。结果石蜡包埋组织检测HPV E6/E7 m RNA的阳性率为48.7%,高于脱落细胞的阳性率40.1%(χ2=4.192,P<0.05)。石蜡包埋组织检测HPV E6/E7m RNA对诊断的灵敏度为75.0%,高于脱落细胞的61.4%(χ2=5.046,P<0.05);石蜡包埋组织检测HPV E6/E7 m RNA对诊断的特异度为81.2%,脱落细胞为77.1%,二者差异无统计学意义(χ2=0.641,P>0.05)。结论检测石蜡包埋样本中的HPV E6/E7 m RNA,可更加精确预测宫颈病变进展风险,对宫颈癌筛查工作具有更好的临床意义。展开更多

The ER gone expression was up - regulated by estrogen and the levels of ER mRNA synchronized with the changes of ER protein, suggesting that estrogen influenced the trsnscriPtional step of the ER gene. Post-coitum ER expression increased with the serum estrsdiol progressively, reached a peak on d4-ds (Just before implantation), but drastically dropped to the nadir on d6-d7 (during implantation) and then recovered. It was of interest to discover that ER mRNA level in the nonimplantstion sites (NIS) of uterus was much higher than that in the implantstion sites (IS).展开更多
