新法有望取代骨移植治疗受损骨骼
骨移植治疗 骨骼
2017/6/21
面对严重骨折或骨缺损，难道只能接受骨移植手术吗？美国研究人员结合基因疗法与干细胞技术，开发出一种新方法，可使严重受损的骨骼自行生长愈合。
美国锡达斯—赛奈医疗中心日前发布新闻公报说，该院领衔的研究团队已在动物实验中成功应用这一方法，相关论文发表在美国《科学—转化医学》杂志上。
动物实验中，研究人员先用胶原蛋白制成支架，填充在受损腿骨的缺口处。大约两周后，支架便已将腿部自身的干细胞引至缺口区域。...

研究揭示抗凝栓药或增加脑出血几率
抗凝栓药 硬脑膜下血肿 发生率
2017/3/2
近日，一项新研究发现，抗凝栓药的使用或能改变硬脑膜下血肿的发生率。这些抗凝栓药物包括低剂量阿司匹林、维生素K拮抗剂（如华法林）、氯吡格雷及口服抗凝药等。相关论文刊登于《美国医学会杂志》。丹麦大学的David Gaist及同事分析了10010位硬脑膜下血肿患者以及40多万名对照组人员的数据。实验组参与者的年龄为20至89岁，他们在2000年至2015年第一次出现硬膜下血肿，其中有47%的人在服用抗凝...
