多层螺旋CT分析周围型肺癌形态学特征—MPR正交重组切面结合MIP
Zhongshan Daxue xuebao. Yixue kexue ban, 2016 【目的】分析多层螺旋CT后处理图像（MPR正交重组切面结合MIP）对周围型肺癌形态学特征的显示价值。【方法】回顾性纳入75例（男：女= 36:39；平均年龄：60.0岁）术前行64排CT检查并经手术病理证实为周围型肺癌的孤立性肺结节。记录结节形态学特征（边缘，分叶征、血管集束征、胸膜凹陷征、毛刺征）分别在横断位，冠、矢状切面及MPR正交重组切面结合MIP（5 mm）图像上的显示率、诊断结果，进行对比分析。【结果】MPR平行肺门支气管血管束方向5 mm MIP 明显提高肺结节血管集束征的检出率 ...

Zhongguo shiyan zhenduanxue, 2018 急性冠脉综合征是引起胸痛的主要病因,除常规监测心电图和心脏生化的动态改变,进一步的冠脉评估非常重要。多层螺旋CT技术侧重于对冠脉进行解剖学的评价,而运动心电图、负荷超声心动图和负荷核素心肌灌注显像等检查,侧重于从功能学角度对缺血进行评估 ...

miR-574-5p negatively regulates tumor suppressors Qki6/7 to impact the signal transduction of beta-catenin and p27Kip1 in colon cancer cells [PDF]
, 2011 QKI是STAR家族信号转导和RNA结合蛋白的一个重要成员。它在正常的结肠上皮细胞中广泛表达，而在结肠癌细胞中却存在不同程度的表达下调甚至缺失。虽然已有的研究表明QKI的表达下调可以通过影响p27Kip1及β-catenin等蛋白分子促进结肠癌细胞的增殖与分化异常，从而参与到结肠癌的发生发展过程中，但是其在结肠癌细胞中被下调的机制尚待进一步的详细阐明。由于许多miRNAs在结肠癌中普遍存在表达失调，且多个研究已表明miRNA参与了结肠癌信号通路中关键分子的调控。因此 ...

Zhongshan Daxue xuebao. Yixue kexue ban, 2017 【目的】总结肠结核（ITB）在多层螺旋CT小肠造影（MSCTE）的表现，探讨MSCTE在ITB的诊断价值。【方法】收集15例经内镜检查或手术后病理确诊为ITB的临床与影像学资料，所有的患者均行MSCTE检查，回顾性分析其MSCTE表现，包括病灶的位置、数目、形状、边界和邻近组织的改变，以及腹部其它脏器、腹膜、大网膜和肠系膜的变化，并与内镜及手术结果相对照。【结果】15例ITB中，13例（86%）主要累及回盲部。4例（27%）表现为多节段肠壁均匀增厚，9例（60%）表现为局部肠壁实质性肿块形成，1例（6%）

Zhongguo shiyan zhenduanxue, 2018 胰腺癌是消化系统高发的恶性肿瘤[1],侵袭性强,预后不良。目前根治性手术切除仍然是胰腺癌主要治疗方式,该病没有特异性的临床表现,85%的患者发现时已属疾病晚期,失去了手术切除的机会[2]。因此,早期发现胰腺癌并准确判断其分期,是获得最佳治疗效果的关键。目前多层螺旋CT是胰腺癌主要的影像学检查[3],而能谱CT成像(gemstone spectral imaging,GSI)是一种新兴的检查手段,优化观察目标与背景的对比度和改善图像质量,

Linchuang shenzangbing zazhi, 2014 肾移植一直以来是治疗终未期。肾脏疾病较好的方法。随着尸体肾源的短缺,亲属活体供肾移植是突破器官短缺困境的现实途经[1]。为保障活体供体者的安全,移植肾的质量,术前了解供肾血管、肾实质及输尿管情况,有助于术前制定手术方案的。对已成功捐献肾脏的70例供体,在术前进行多层螺旋CT（multi-slice computed tomography,MSCT）平扫、三期增强扫描的资料进行回顾性分析,并与术中所见副肾动脉的数目相对比,评估临床应用价值。
