We presumed that amentoflavone exerts a neuroprotective effect in epilepsy models. Prior to model establishment, mice were intragastrically administered 25 mg/kg amentoflavone for 3 consecutive days. Amentoflavone effectively prevented pilocarpine-induced epilepsy in a mouse kindling model, suppressed nuclear factor-κB activation and expression, inhibited excessive discharge of hippocampal neurons resulting in a reduction in epileptic seizures, shortened attack time, and diminished loss and apoptosis of hippocampal neurons. Results suggested that amentoflavone protected hippocampal neurons in epilepsy mice via anti-inflammation, antioxidation, and antiapoptosis, and then effectively prevented the occurrence of seizures.展开更多
目的评价人乳头状病毒(human papilloma virus,HPV)E6/E7 m RNA检测在宫颈癌筛查中的应用价值。方法采用支链DNA(b DNA)杂交核酸检测技术对1019例已行液基细胞学(thinp rep cytologic,TCT)检查的标本进行高危型HPV E6/E7 m RNA检测,对照...目的评价人乳头状病毒(human papilloma virus,HPV)E6/E7 m RNA检测在宫颈癌筛查中的应用价值。方法采用支链DNA(b DNA)杂交核酸检测技术对1019例已行液基细胞学(thinp rep cytologic,TCT)检查的标本进行高危型HPV E6/E7 m RNA检测,对照TCT结果判断检测敏感性及特异性。结果细胞学异常组的拷贝数显著高于细胞学阴性组(P<0.05),细胞学病变级别越高,对应的HPV E6/E7 m RNA表达率越高,具有相关性;HPV E6/E7 m RNA检测敏感度73.37%,特异度80.57%。结论宫颈病变与HPV E6/E7 m RNA转录有关,检测HPV E6/E7 m RNA对宫颈癌筛查具有临床应用价值。展开更多
