简介：这研究是在RGD-FasL和内在的机制导致的垂体腺瘤房间线GH3/MMQ/AtT20上调查细胞毒素的效果。Fas/DcR3mRNAs被RT-PCR检测，他们的表面表情被流动cytometry测量。RGD-FasL在肿瘤房间上施加的Cytotoxicity与MTT试金被测量，导致的apoptosis被agarose胶化电气泳动决定。房间周期和apoptosis被流动cytometry估计，PI染色。caspase8/9/3，Bcl-2，RANKL和JNK2的表情被西方的弄污检测。约13.7%GH3房间，25.5%MMQ房间，，22.2%AtT20房间表示船边交货23.9%GH3房间，24.1%MMQ房间，4.6%AtT20房间表示DcR3。肿瘤房间上的FasL/RGD-FasL的细胞毒素的效果都以一种剂量依赖者方式被拿。房间线MMQ/AtT20至于FasL显示出一样的敏感到RGD-FasL，当房间线GH3对RGD-FasL不太敏感时。房间周期分析显示RGD-FasL能在G0/G1阶段和G2/M阶段禁止房间。在与RGD-FasL对待的MMQ和AtT20房间，AI不与，在与RGD-FasL对待的GH3房间与FasL对待那显著地不同，AI比与FasL对待的低。当Bcl-2的与RGD-FasL在处理以后被减少时，caspase-8/9/3，RANKL和JNK2的表情被增加，建议RGD-FasL导致通过caspase激活的apoptosis。我们断定RGD-FasL能可能被看作垂体腺瘤的处理的一个新奇therapeutical候选人。

简介：AbstractBackground:Although the incidence and clinical manifestations of pituitary apoplexy were reported by a few researches, the results are not consistent. This study aimed to explore the risk factors associated with an incidence of apoplexy in pituitary adenomas.Methods:The clinical information of 843 patients with pituitary adenoma from the Department of Neurological Surgery, 1st Affiliated Hospital of Kunming Medical University, was reviewed. The incidence, clinical manifestation, and potential risk factors for pituitary apoplexy were analyzed by a case-control study.Results:In total, 121 patients (14.4%) with macroadenoma were suffered from pituitary apoplexy. Headache, vomiting, and visual impairment are the top 3 symptoms for the pituitary apoplexy. Logistic regression results showed that the hypertension(hypertension vs non-hypertension OR = 2.765, 95%CI: 1.41~5.416), tumor type (negative staining vs. positive staining, OR = 1.501, 95%CI:1.248~5.235), and tumor size (diameter > 2 cm vs. diameter ≤ 2 cm, OR = 3.952, 95%CI:2.211~7.053) are independent factors associated with pituitary apoplexy.Conclusion:Our results indicate that the risk factors for the incidence of pituitary apoplexy depend mainly on properties of the tumor itself (tumor size and pathologic type) and the blood pressure of patients.
