细胞死亡方式的新理念

起初人们认为不同细胞死亡方式之间潜在的细胞调节是不同的,然而,近来的研究显示细胞死亡的潜在机制较复杂,在一定情况下,不同细胞死亡方式之间相互联系甚至相互转化。对几种细胞死亡方式之间的区别和联系进行了回顾,有助于评价关键的细胞死亡途径,发现新的治疗干预措施。     

电视胸腔镜下肺癌切除术应用体会

电视胸腔镜手术被视为20世纪末期胸外科界革命性的一大突破,是微创胸腔外科应用范围最为广阔的胸腔镜手术。其中,腔镜下治疗非小细胞肺癌的肺叶切除术是胸外科微创的代表性手术,其创伤小、恢复快、并发症发生率低等优点日益明显。尽管胸腔镜肺癌切除的安全性及有效性得到普遍认可,而且胸腔镜手术治疗早期肺癌患者也取得了良好的效果,但目前...     

‘What made me unhappy’. Experiences of,and responses to,lifestyle changes in breast cancer patients

Sixteen breast cancer patients were interviewed about any lifestyle changes they had experienced and their reactions to those changes. Data were collected and analysed via content analysis and then summary tabulations of patient responses until replication of responses was verified across patients. Results indicated that most patients suffered a reduction in recreation activities, unpleasant physical side effects from treatment and loss of feminine appearance characteristics, all of which were seen as decreases in previously available and valuable sources of social support and self-esteem. In response to these losses, patients reported a common coping strategy of avoidance or escape similar to some depressive symptomatology. Implications for counsellors are discussed.     

癌症化疗患者护患沟通环节流程化模式初探

在癌症化疗患者的整体护理中,护患沟通较之躯体护理更具挑战性,表现为沟通难做、效果难评、学生难带、绩效难考。作者尝试一种模式,把护患沟通的各环节工作流程化、任务表格化,即首先按精心设计的流程及内容完成针对性调查,找出影响与患者沟通的有关因素及患者最为关注的问题,针对性地运用各种沟通技巧逐一沟通,实现护患沟通的个体化和差异化,同时使护患沟通环节工作有模式、效果有评价、教学有路径、考核有标准。     

干细胞移植治疗缺血性心脏病研究的新途径:miRNAs

miRNAs在干细胞的自我更新、多向分化及分泌血管活性物质等过程中扮演作非常重要作用。近年来人们对于干细胞移植术治疗缺血性心脏病,取得了一定的成果,但仍然存在着大量有待解决的问题。例如如何增加移植后的干细胞存活率;改善梗死区的微环境,增加迁移或归巢到梗死区干细胞的数量等,而miRNAs在干细胞中的调节机制且表明miRNAs有可能成为干细胞移植研究的一个新的切入点。     

结直肠癌相关肿瘤标志物的最新研究进展

结直肠癌是最常见的恶性肿瘤之一。其起病隐匿、病死率较高,治疗成功的关键在于早期发现、早期诊断,结直肠癌相关肿瘤标志物曾为此做出了贡献。近年又发现了许多新的结直肠癌相关肿瘤标志物,其中有的已进入临床应用,还将有更多标志物为结直肠癌的早期诊断、疗效观察、预后判断和复发监测提供新思路和新方法。     

大肠癌靶向药物治疗进展评述

21世纪以来,靶向药物如抗VEGF的人源化单克隆抗体(Bevacizumab,贝伐单抗)和抗EGFR单克隆抗体(人鼠嵌合性单抗Cetuximab,C225,西妥昔单抗和全人源化单抗EGFR抗体,Panitumumab,帕尼单抗)的临床应用,已使复发转移性结直肠癌患者的总生存取得了长足的进步,但临床上应如何更加合理有效地使用这些药物,仍有许多亟待解决的问题。     

重视直肠癌术后局部复发的防治

直肠癌术后局部复发是临床关注的重点与难点问题。术前准确分期、评估,选择合理治疗方案和术式,是防治局部复发的先决条件。手术遵循全直肠系膜切除(TME)原则,保证断端切缘和环周切缘完整、无癌细胞残留是防治局部复发的关键。新辅助治疗可降低T3、T4期直肠癌局部复发率。发挥直肠癌多学科综合治疗模式优势对防治直肠癌局部复发有重要作用。     

晚期癌症患者治疗决策的思考

现代医疗尚无法治愈所有晚期癌症。现实与期望之间的较大差距,挑战晚期癌症治疗的临床决策。WHO强调为防止资源滥用,应确保抗癌治疗只用于可获益阶段。对于晚期癌症患者的治疗决策,除遵循规矩原则和循证医学证据原则外,还应该遵循尊重患者意愿、社会公平的美德原则。大多数癌症患者需要接受姑息治疗。姑息治疗为患者及家属提供既简便又经济的医疗服务。     

MUSLIM PERSPECTIVES ON STEM CELL RESEARCH AND CLONING

In Islam, the acquisition of knowledge is a form of worship. But human achievement must be exercised in conformity with God's will. Warnings against feelings of superiority often are coupled with the command to remain within the confines of God's laws and limits. Because of the fear of arrogance and disregard of the balance created by God, any new knowledge or discovery must be applied with careful consideration to maintaining balance in the creation. Knowledge must be applied to ascertain equity and justice for all of humanity. Research in Islam must be linked to the broad ethical base set forth in the Qur'an and the Sunnah. Whether embryonic stem cell research or cloning is ethically acceptable in Islam depends on the benefits derived from such applications. What is most important for the scholars is to adhere to the concepts of compassion, mercy, and benefit to everyone.
