下肢深静脉血栓患者血液流变学指标的变化

目的：研究下肢深静脉血栓患者血液流变学指标的变化。方法：对40例下肢深静脉血栓患者和50例正常对照者分别进行血液流变学指标的检测。结果：下肢深静脉血栓患者组的全血粘度、血浆粘度、血沉、全血低切还原粘度、血沉方程K值、红细胞聚集指数及全血低切相对粘度与正常组对照，均有显著性差异（P〈0．01）。结论：下肢深静脉血栓患者存在明显的血液流变学改变和微循环障碍。提示治疗过程中，可采用抗凝、活血化淤方法改善血液流变学、降低血液粘度；并将血液流变学指标作为监测病程、判断预后、指导用药的重要指标。

疏血通对髋部骨折患者凝血-纤溶功能影响的临床研究

目的:评估疏血通对髋关节手术患者术后凝血-纤溶系统的影响.方法:选择2002年7月～2003年4月髋部手术患者共57例,根据入院时间(单双日)分为治疗组(34例)和对照组(23例),手术前3d开始分别采用疏血通和低分子肝素治疗,共10d,于用药前、术前、术后第1天、术后第3天、术后第7天,测定白陶土部分凝血活酶时间(KPTT)、凝血酶原时间(PT)、组织型纤溶酶原激活剂(t-PA)、组织型纤溶酶原激活剂抑制剂(PAI)、D-dimer、血小板聚集率,怀疑有深静脉血栓(DVT)者行静脉造影检查.结果:两组治疗前后KPTT,PT明显延长;治疗组t-PA活性明显增强(P＜0.05),D-dimer升高,PAI无明显变化,并抑制血小板聚集.结论:疏血通在预防和治疗髋关节术后静脉血栓形成中,不仅有抗凝作用,而且能激活纤溶系统,抑制血小板聚集,是一种安全有效的药物.     

The heat shock response: Role in radiation biology and cancer therapy

Since prehistoric times, elevated temperatures have been used to treat cancer in a variety of forms. In modern times (the last 40 years) efforts have concentrated on combining heat with other anti-tumour modalities, principally ionizing radiation and some chemotherapeutic drugs. Despite the emphasis on combined therapy, rodent data relating to heat sensitivity and thermal tolerance development assumed principal importance. These considerations suggested treating at 43°C as a target temperature and fractionation schemes emphasizing thermal tolerance avoidance. Concomitantly crucial data on heat-induced tumour reoxygenation and its temperature dependence were largely ignored. In reality these were unrealistic and undesirable goals. The preponderance of evidence now suggests that lower temperatures (40–42°C) administered more frequently, optimally immediately before and during each administration of ionizing radiation, are likely to yield optimal results. Factoring in trimodality therapy and other combinations of chemotherapeutic drugs will require some modifications of such fractionation schemes.     

帕金森病脑深部刺激术后FDG—PET／CT变化及临床意义

目的研究帕金森病（PD）脑深部刺激术（DBS）后全脑葡萄糖代谢（FDG）正电子发射断层扫描（PET）／计算机断层扫描（CT）功能影像学变化，探讨其评估手术疗效的临床价值。方法2011年2月至2011年7月，18例接受丘脑底核（STN）DBS治疗的PD患者分别在术前1w和术后6个月进行脑部18-F—FDG—PET／CT。结果术前大部分PD患者FDG影像学表现符合PD相关模式（PDRP）。术后异常代谢区域代谢趋向正常改变：纹状体区、中脑、感觉运动区和运动前区皮层的异常高代谢有明显下降；双侧前额叶、扣带回和辅助运动区皮层的异常低代谢有轻度升高。结论FDG影像对PD的诊断、鉴别诊断、病情评估和手术疗效有指导意义，但目前尚不能指导临床手术。     

Artificial intelligence for the early detection of colorectal cancer: A comprehensive review of its advantages and misconceptions

Colorectal cancer (CRC) was the second-ranked worldwide type of cancer during 2020 due to the crude mortality rate of 12.0 per 100000 inhabitants. It can be prevented if glandular tissue (adenomatous polyps) is detected early. Colonoscopy has been strongly recommended as a screening test for both early cancer and adenomatous polyps. However, it has some limitations that include the high polyp miss rate for smaller (< 10 mm) or flat polyps, which are easily missed during visual inspection. Due to the rapid advancement of technology, artificial intelligence (AI) has been a thriving area in different fields, including medicine. Particularly, in gastroenterology AI software has been included in computer-aided systems for diagnosis and to improve the assertiveness of automatic polyp detection and its classification as a preventive method for CRC. This article provides an overview of recent research focusing on AI tools and their applications in the early detection of CRC and adenomatous polyps, as well as an insightful analysis of the main advantages and misconceptions in the field.
