乳腺癌是女性发病率最高的恶性肿瘤[1]。在临床中,乳腺癌早诊断、早治疗可改善其预后,有效降低死亡率[2,3]。但乳腺癌早期大多没有明显的临床症状及体征,易被忽略,因此在乳腺癌筛查的过程中,我们需要借助于影像学方法。在众多影像学方法中,乳腺X线摄影技术占据了重要地位,但传统的数字化乳腺摄影(DM)及全数字化乳腺摄影(FFDM)对于微小病灶及致密型乳房内病灶的敏感度相对较低[4],而乳腺断层合成X线成像技术(DBT)的出现则在一定程度上改善了上述问题。

DHA藻油是补充ω-3多不饱和脂肪酸的重要非动物来源,但因其自身水溶性差、易氧化产生不良风味等特点,极大约束了其摄入途径。据此,采用高压微射流技术与逐层沉积技术(LBL)制备负载DHA的亚麻籽胶(FG,质量分数为0.4%)-紫苏分离蛋白(PPI,质量分数为0.225%)双层乳液,研究Ca2+添加量(0%~0.5%)对上述双层乳液体系稳定性的影响;同时,采用INFOGEST体外模拟消化模型,探究PPI-DHA藻油单层乳液、FG-PPI-DHA藻油双层乳液、Ca2+-FG-PPI ...

CT imaging anatomy of myocardial bridge-mural coronary artery and its relationship with atherosclerosis [PDF]
研究背景:心肌桥-壁冠状动脉(MB-MCA)是一种先天性冠状动脉解剖变异,一直被认为是种良性病变。一般情况下,不引起临床症状,但可能出现心肌缺血、心律失常、心肌梗死及猝死等临床表现。明确MB-MCA的形态学特征及其与冠状动脉粥样硬化之间的关系,为相关疾病的诊断及治疗提供解剖依据。 目的:(1)应用64排多层螺旋CTA观察并测量MB-MCA发生率及其形态学特征;(2)探讨左前降支心肌桥(LAD-MB)与冠状动脉粥样硬化的关系。 实验方法:(1)回顾性分析本院2013.05-2014 ...

人胚胎视网膜对~3H-甘氨酸、~3H-天门冬氨酸的摄取和释放的实验研究
本文应用同位素示踪和放射自显影技术,观察了新鲜人胚胎22例视网膜神经元体外摄取和释放3H-甘氨酸和3H-天门冬氨酸功能的出现。结果表明,14~15周人胚胎视网膜已具有摄取和K+刺激、Ca++依赖性释放外源性3H-甘氨酸和3H-天门冬氨酸的能力。摄取和3H-甘氨酸的细胞是视网膜内核层最深层的细胞,摄取和蓄积3H-天门冬氨酸的细胞是内核层中部和外核层的部份细胞,根据细胞形态和所在位置,我们认为这些细胞分别是发育中的无长突细胞,双极细胞和视锥细胞。此外,在3H-天门冬氨酸的放射自显影图像中,可见视网膜的外核层、
