简介：采取硬度检测、拉伸试验、金相检验和化学成分分析等方法,对不同铸造工艺HT250铸件的表面孔洞缺陷进行调查与分析。结果表明：HT250铸件硬度明显低于国家标准要求,部分铸件的抗拉强度不满足国家标准要求,金相组织中铁素体含量较高（珠光体含量低于85%）,石墨粗大、不均匀,化学成分不满足企业标准要求。孔洞缺陷是其加工表面在高速切削力作用下,石墨块脱落并同时牵扯着周边的铁素体一起塌陷下来,从而形成大小不等的凹坑。

简介：摘要了解HT相关危险因素，在溶栓及抗栓治疗前发现出血转化高危人群，对于减少HT的发生及改善急性缺血性卒中预后至关重要。本文的目的就是研究非症状性出血性转化对急性脑梗死后3个月的功能是否有影响及与其相关独立危险因素。脑梗死后非症状性出血转化影响患者的远期预后（OR=5.86,p<0.001）。asHT相关独立危险因素有房颤、大面积脑梗死、初始高NIHSS评分。后循环脑梗死为非症状性出血转化发生率低的预测因素。

简介：摘要目的5-羟色胺受体(5-HT1A和5-HT3受体)在七氟烷诱发老龄大鼠脑神经毒性中的作用。方法清洁级健康雄性SD大鼠24只，18～20月龄，体重600～750 g，采用随机数字表法分为3组(n＝8)：分别吸入50%O2(C组)、1.5%七氟烷+50%O2(LS组)及3%七氟烷+50%O2(HS组)，持续2 h。于吸入七氟烷前1 d及结束后1 d时行旷场实验，记录中央格停留时间、跨格次数和站立次数；于吸入七氟烷前6 d时及结束后第1天行水迷宫实验，记录逃避潜伏期、游泳总距离和穿越平台次数。行为学实验结束即刻取海马组织，采用RT-PCR法和免疫组化法检测5-HT1A和5-HT3受体的mRNA表达水平及阳性细胞数。结果与C组比较，HS组中央格停留时间延长，跨格次数及站立次数减少，逃避潜伏期延长，游泳总距离增加，穿越平台次数减少，5-HT1A和5-HT3受体的mRNA表达下调，阳性细胞数减少(P<0.05)。结论七氟烷诱发老龄大鼠脑神经毒性的机制可能与下调5-HT1A和5-HT3受体活性有关。
