Zhongguo shiyan zhenduanxue, 2018 目的探究MRI对直肠癌放化疗前后对比预后的预测价值。方法选取2015年-2016年在我院接受住院治疗的直肠癌患者100例作为研究对象,采用超导磁共振扫描仪对患者进行MRI扫描,根据胃癌TNM分期标准,将MRI检查结果与术后病理检查结果相比对,判定MRI扫描检查结果的准确度和一致性。待患者接受放化疗治疗前、接受放化疗治疗后和放化疗结束一个月后,由两名以上专业医师对患者的MRI扫描结果进行采集分析,判定直肠癌肿瘤长度和肿瘤肠壁厚度的变化情况。待患者放化疗结束后,根据实体瘤疗效评价标准对患者进行分组。结果 ...

FoxO3 Inactivation Promotes Human Cholangiocarcinoma Tumorigenesis and Chemoresistance through Keap1-Nrf2 Signaling [PDF]
, 2016 许多人类肿瘤中存在PI3K/AKT过度激活，然而该通路的异常导致肿瘤形成的分子机理仍未充分阐明。FoxOs是受PI3K/AKT负向调控的转录因子，与肿瘤形成密切相关，但对于FoxOs调控肿瘤生长的机制尚不十分清楚。胆管癌是一类起源于胆道上皮细胞的恶性肿瘤，胆管癌患者对化疗敏感性差，但耐药机理尚未充分阐明。Nrf2的激活与胆管癌耐药性及病人不良预后密切相关。高度激活的PI3K/AKT能够激活Nrf2信号通路，但其中具体的分子机制尚不清楚。Keap1是连接Nrf2与Cul3的衔接蛋白 ...

Huli yanjiu, 2016 摘要： 雾化吸入和氧气吸入在临床上广泛用于呼吸疾病的治疗。目前，在利用雾化给药器进行雾化治疗时，通常都是将药物的雾化治疗与对病人的吸氧辅助治疗完全分开进行，即通过雾化给药器进行雾化治疗时，需要同时给病人佩戴鼻部吸氧导管进行吸氧辅助治疗。但是，在雾化治疗过程中，病人吸入雾化后的药物时，经口吸入经鼻呼出，不能同时有效吸入氧气，经常出现血氧饱和度下降的情况，甚至因病人缺氧不得不终止雾化吸入治疗，从而降低药物雾化治疗的效果。为此，我们设计了一种新型的雾化吸氧给药器，有效地解决了此问题。
