Synthesis of MnO@Au nanocomposite and its applications in multifunctional imaging and photothermal treatment [PDF]
, 2016 肿瘤的诊断，特别是针对高致死性和侵袭性肿瘤的早期诊断，已经越来越得到人们的重视。但是，目前癌症的早期诊断也同癌症治疗一样，仍然是一项充满难度与挑战性的一项工作。现在的诊断方法包括了X射线计算机断层扫描技术(CT)，磁共振（MRI），超声成像（US），以及当下兴起的光声层析成像技术（PAI），由于每种成像方式都有其固有的缺点，所以任何单一成像方式都不能获得完全关于癌症的信息。本文设计了一种非常简便的方法，在室温条件下，第一次合成出以MnO和Au为基的草莓状MnO@Au复合纳米材料，实现了集MRI，CT ...

血清AFU、LAP和GGT联合检测在早期原发性肝癌诊断中的应用与评价
Zhongguo shiyan zhenduanxue, 2016 我国是肝炎发病大国,肝癌发病率也呈逐年上升的趋势,是临床常见的疾病。据统计,每年大约有11万人因肝癌死亡。肝癌一般起病比较隐蔽[1],早期无典型的临床症状,临床上一旦确诊一般属于中、晚期。因此,如何早期诊断肝癌具有重要的意义[2]。现阶段,临床上应用甲胎蛋白和影像学方法辅助诊断早期肝癌,但早期肝癌的诊断率仍然较低。a-L盐藻糖苷酶(a-L Salina glucosidase AFU ...

Design, synthesis and preliminary bio-evaluation of progestrone receptor targeting probes for breast cancer imaging with PET [PDF]
, 2016 乳腺癌是严重威胁女性健康的疾病，它的早期诊断能够有效的降低病人的死亡率。孕激素受体属于核受体超家族，有PRA和PRB两种亚型，在调节和控制卵巢，子宫和乳腺的功能方面有重要作用。研究表明，在雌激素受体阳性（ER+）的乳腺癌病人中，PR的表达与否不会对病人接受他莫西芬治疗的疗效产生影响。但是在雌激素受体表达阴性（ER-）的乳腺癌病人中，病人接受他莫西芬治疗的疗效依赖于PR的表达。因此，监测PR的表达对乳腺癌的早期诊断和ER-/PR+病人的治疗都是很重要的。PET的灵敏度高，空间分辨率好，安全性也较好 ...

Ovarian ectopic pregnancy: clinical characteristics, ultrasound diagnosis and management
Ultrasound in Obstetrics &Gynecology, Volume 63, Issue 6, Page 815-823, June 2024.ABSTRACT Objective To compare the clinical, ultrasound and biochemical characteristics of ovarian ectopic pregnancy (OEP) with those of tubal ectopic pregnancy (TEP). Methods This was a retrospective case–control study of women with OEP and those with TEP seen at a single center between December 2010 and February 2021.

PET Imaging and Targeted Radiotherapy of Integrin αvβ3 Positive Tumors [PDF]
, 2016 目的：含有三肽序列的精氨酸-甘氨酸-天冬氨酸（Arg-Gly-Asp，RGD）的配体和整合素αvβ3具有特异性和高亲和力，因此利用RGD与整合素αvβ3特异性结合而设计的放射性核素标记的RGD分子探针在肿瘤显像方面得到了广泛的研究和应用。然而，放射性核素标记的RGD分子探针在肿瘤治疗方面的研究却并不多。本研究中，我们创造性的将环状多肽RGDfK与白蛋白结合基团伊文思蓝（EvansBlue，EB）共价结合，以期构建一种可长时间存在于体内循环的长效分子探针EB-RGD ...

缺血修饰白蛋白与平板运动试验联合检查对早期冠状动脉综合征的临床诊断意义
Zhongguo shiyan zhenduanxue, 2010 目的探讨缺血修饰白蛋白（IMA）测定与平板运动试验联合诊断早期冠脉综合征的临床应用价值。方法以30例体检健康者做为对照,对80例心肌缺血、缺氧症状患者分别进行平板运动试验（TET）、冠状动脉造影（CAG）以及检测其运动前后的IMA值。比较运动试验前后患者与健康对照组IMA测定值的变化;以冠脉造影结果为标准,分别评价IMA、TET、IMA联合TET对于诊断早期冠状动脉综合征敏感性与特异性。结果运动试验前试验组IMA值与对照组差异显著 ...

Prenatal diagnosis and postnatal outcome of Type‐III vasa previa: systematic review of literature
Ultrasound in Obstetrics &Gynecology, Volume 63, Issue 1, Page 24-33, January 2024.ABSTRACT Objective Type‐III vasa previa (VP) is a rare form of VP, not necessarily associated with other placental or vascular anomalies, in which aberrant vessels run from the placenta to the amniotic membranes, near the internal cervical os, before returning to the placenta. Early diagnosis of Type‐III VP is important but technically challenging. The
