Bone Replacement Materials in Hand Surgery

Abstract Background: In recent years, biomaterials are being found and frequently utilized in bone defects. They have also gained significant precedence in hand surgery. Objectives: The respective requirements for such replacement material will be cited and acknowledged in this article. The individual material groups will also be referred to in this review. An introduction to some of the customary bone replacement materials will be cited and concluded with a corresponding recommendation. Conclusion: The implantation of autologous cancellous bone is still regarded today as the “gold standard”. Nevertheless, the usage of bone replacement material can be an enormous advantage in certain indications.

抗生素的合理使用

随着医药工业的发展,新药层出不穷。以抗生素为例,20世纪50年代临床用的抗生素只有青、链、红、氯四大素,现在常用临床的抗生素以有100多种,临床医生长期来忙与医疗任务,如何掌握新药信息,做到合理选药,合理用药,使药物的药理作用转化为治疗效应,已成为临床医生日益关心的问题。1抗生素在临床应用中存在问题1.1常规固定方案长期以来根据以往的经验或资料,正式或非正式采用抗生素治疗方案。如:氨苄西林+庆大霉素、青霉素+庆大霉素、红霉素+氯霉素。由于对致病菌针对性不强,以致延误治疗。1.2抗生素在选择中存在问题随着医药工业的发展,抗生素…     

法莫替丁治疗消化性溃疡60例

60例(男50,女10,年龄43±8a)经内窥镜证实的活动性消化性溃疡患者,口服法莫替丁40mg,qn,疗程2-4wk或延至6-9wk。溃疡愈合率DU2,4,6 wk分别为50％,84％,92％,SU2,4,6,8 wk分别为40％,68％,73％,82％。服药后3,7,14 d上腹痛缓解率DU为50％,80％,100％,SU为40％,75％,95％。未见严重不良反应。故法莫替丁对溃疡病,尤其是DU是一有效和安全药物。

MANAGEMENT TO PREVENT BLEEDING DURING ENDOSCOPIC SUBMUCOSAL DISSECTION USING THE FLUSH KNIFE FOR GASTRIC TUMORS

The gastric vasculature responsible for intraoperative bleeding in endosocpic submucosal dissection (ESD) is the ramified vascular network occupying the middle of the submucosal layer and large vessels penetrating the muscle layer. Appropriate management for these vessels must be addressed. The trimming of the ramified vascular network can be safely performed with coagulation mode following shallow mucosal cutting. A large penetrating vessel usually requires precoagulation prior to dissection. These procedures are effectively performed with the water jet short needle knife (Flush knife).     

子宫内膜体外构建及其应用研究进展

体外构建子宫内膜是利用组织工程学原理,在体外构建结构、形态与功能上与体内子宫内膜相似的三维模拟体。种子细胞分离培养、生物支架材料的合理选择及体外构建方法的优化是体外构建子宫内膜的重要因素。构建的子宫内膜在病理研究、三维培养体系、胚胎发育学及移植等方面具有重要的研究意义。只有更进一步模拟自然子宫的结构,优化构建技术路线和培养条件,才可以再造出真正意义上的组织工程化子宫。     

环孢霉素A滴眼治疗角膜移植排斥反应

应用0.5％环孢霉素A(cyclosporin A,CsA)滴眼治疗穿透性角膜移植术后发生免疫排斥患者16例(16只眼),治愈9只眼,好转6只眼,无效1只眼。随访5～24个月,其中2只眼因停药复发,1只眼于拆线后复发,继续用药或增加给药次数后治愈。研究表明0.5％CsA滴眼剂治疗术前移植床条件较好,角膜移植术后发生免疫排斥的病例可得到良好疗效;而对术前移植床条件较差,角膜移植术后发生免疫排斥的病例有一定的疗效。作者对眼局部应用CsA治疗角膜移植排斥的疗效和作用机理进行了讨论。
