组织工程骨在口腔颌面部骨缺损中的应用与思考

组织工程已经开始应用于口腔医学领域,组织工程骨在治疗牙槽骨缺损,上颌骨及下颌骨缺损方面也取得了很大的进展,为颌面骨缺损的修复开辟了一条新途径,但同时也存在技术方面的不足和伦理学问题.     

骨髓间充质干细胞移植治疗对心肌梗死后心功能的影响

目前心肌梗死常规治疗不能修复已死亡或者濒死的心肌,应用干细胞替代受损或死亡的心肌细胞来改善心功能,已成为近年来国内外研究的热点。骨髓间充质干细胞通过修复坏死心肌、促进血管新生等改善心梗后心功能,其移植治疗有望成为治疗心肌梗死的一个全新方法。     

骨巨细胞瘤外科治疗几个问题的思考

骨巨细胞瘤是临床上常见的骨肿瘤,其治疗方式由以前的截肢术发展到保肢术,一直到现在的多种局部切除与功能重建方式,透过其治疗理念的更新,以及手术技术的转变,不难看出临床医生应重视循证医学实践,不断更新观念,坚持个体化治疗,明确切除范围、切除方式与重建方法及肢体功能之间的关系,不断改善患者的生活质量。     

关于牙齿再生研究的述评

牙齿再生医学是目前口腔医学中面临的最为重要的科学问题,成为口腔医学研究领域的热点。无论从牙发育生物学到牙生物信息学到牙组织工程技术,由此而得到了很大程度的发展。但是,这个领域目前面临许多问题。就有关研究的现状、困惑、面临的问题进行探讨,对于牙再生医学研究的模式,从方法论的角度提出探讨。引发相关研究领域研究人员思考,以早日实现牙齿组织再生,满足人们需要。     

生物自组织临界性与肿瘤

分析了局部组织由再生、化生和癌变呈现的各种宏观行为和性质,从生物自组织临界性的角度讨论了这类行为和性质的演化模式及机制,指出肿瘤实质是局部组织经历一系列临界状态下相变造成的。     

急性有机磷农药中毒救治中的几个问题

解决急性有机磷农药中毒病死率居高不下的问题,必须提高救治中的辩证思维.正确理解标本兼治的含义,外周性、中枢性抗胆碱药物和复能剂联合应用,合理维持阿托品化,积极应用机械通气进行必要的呼吸支持治疗和适时行血液灌流治疗是救治有机磷农药中毒的有效保证.     

人类胚胎干细胞的来源与伦理思考

人类胚胎干细胞研究的伦理问题较多,因此要思考胚胎干细胞的伦理问题。胚胎干细胞来源有四种：选择性流产的人类胚胎组织;治疗不孕症夫妇不需要的由体外受精产生的人类胚胎;由捐献者专门为研究所捐献的配子由体外受精产生的人类胚胎;由体细胞核移植技术将人体细胞核移植入人或动物的卵泡内产生人类胚胎或嵌合体胚胎。用不同胚胎来源研究干细胞产生的伦理问题不同,伦理的思考和结论也不同。     

Modern medicine and biotechnology: an ethical conflict of interest?

When confronting the issues related to developments in modern medicine and biotechnology, we must repeatedly ask ourselves anew what can and cannot be justified in an ethical sense. For radically new ethical questions seem to arise through innovative techniques such as stem cell research or preimplantation diagnosis — and with them new areas of conflicting interests. If one scrutinizes the previous positions related to this subject, it becomes conspicuous that a multitude of questions has quickly piled up — however, (as in the case of Germany) comprehensive and differentiated views have mostly been lacking. An earlier version of this paper was presented at an International Conference on “Conflict of Interest and its Significance in Science and Medicine” held in Warsaw, Poland on 5–6 April, 2002.     

Abortion and the human animal.

I discuss three topics. First, there is a philosophical connecting thread between several recent trends in the abortion discussion, namely, the issue of our animal nature, and physical embodiment. The philosophical name given to the position that you and I are essentially human animals is "animalism." In Section II of this paper, I argue that animalism provides a unifying theme to recent discussions of abortion. In Section III, I discuss what we do not find among recent trends in the abortion discussion, namely "the right to privacy." I suggest some reasons why the right to privacy is conspicuous by its absence. Finally, I address Patrick Lee's claim that the evil of abortion involves "the moral deterioration that the act brings to those who are complicit in it, and to the culture that fosters it."
