卵巢良性肿瘤诊断与治疗的思考

卵巢肿瘤位于盆腔深处早期没有症状,为临床诊治造成一定困难。如何在早期鉴别诊断卵巢肿瘤的良恶性?对卵巢肿瘤的处理原则有无规律可循?对治疗卵巢肿瘤引起的急腹症有无新的进展?在微创手术中如何保护正常卵巢组织?如何监测评价卵巢功能?本文将重点进行探讨。     

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。     

On the Constitution and the True Aim of The Joy of Heaven and Non-Speech： A Reinterpretation of the Debate at the Dam over the Hao River

The essay starts by questioning how the debate at the dam over the Hao River between Zhuang Zi and Hui Zi arose. It describes the source of ideas that led Zhuang Zi to speak on the enjoyment of the fish (yuzhile 鱼之乐) and points out that the meaning of the debate rests in bringing about the emergence of the true subject of “enjoyment.” It highlights this meaning by analyzing the essential content and value orientation of Zhuang Zi’s ideas on the joy of heaven (tian le 天乐) and perfect enjoyment (zhile 至乐). Following up on this thread, the essay goes further to analyze the true meaning of Zhuang Zi’s theory concerning the “great speech” of “non-speaking.” This essay holds that the debate is a parable, an external representation that unfolds an internal tension between two different levels contained within Zhuang Zi’s thought, rather than simply a debate between these two thinkers.     

‘But everyone else is doing it’: a closer look at the occupational taxpaying culture of one business sector

When individuals embark on their careers they not only become acculturated into their occupational sectors' day‐to‐day norms and practices, but also their taxpaying ones. Although the research on taxpaying cultures is still in its infancy, understanding more about taxpaying cultures could improve our understanding of the processes underlying tax compliance. To this end, this study aimed to build a detailed picture of the taxpaying culture (i.e. the norms and values) of one business sector—the hairdressing/beauty industry. Nineteen small business and self‐employed hairdressers/beauticians were interviewed and a variant of Grounded theory was used to uncover the main themes that ran through the interviews as a whole. The main themes that emerged—which appear to characterize this sector's culture—include a reliance on accountants/tax advisors, the notion of an acceptable level of cash‐in‐hand payments, and the use of different mental accounts for different types of income. Although some of these themes have already arisen in the small business literature they have often been couched in individualistic terms. We build a case that these issues are more cultural than individual—they are tied to occupational group membership as they are socially constructed within occupational groups and are a key component of the group's taxpaying culture. Implications and directions for future research are discussed. Copyright © 2007 John Wiley & Sons, Ltd.     

辩证思维在头颈肿瘤诊治过程中的应用

辩证思维贯穿于整个临床诊疗过程中,每位医师在做出临床决策时,均自觉或不自觉地遵循着该原理。在头颈肿瘤的临床实践中,也应始终遵循辩证思维,使哲学思维和科学思维密切结合。合理、正确地运用辩证思维方法有助于深入认识头颈肿瘤疾病的发生、发展及演变过程,从而采取合理、有效的治疗措施。     

厌而避额外之“利”；喜而趋额外之“害”

趋利避害是生物的本能。《管子·禁藏》云：夫凡人之情, 见利莫能勿就, 见害莫能勿避。“两利相权取其重, 两害相权取其轻”是规范性决策理论的一基本原则。本研究以金钱作为奖赏或惩罚刺激, 检验人们能否理性地遵循“价值最大化”原则。在实验中, 主试以检查硬币生产年代的数目为由, 让被试逐枚地感受两个金钱序列：10元硬币序列(由20枚五角硬币组成)和10.3元硬币序列(由20枚五角硬币和3枚一角硬币组成),随后评定获得(或损失)各金钱序列的高兴(或不高兴)程度, 并从中选择一金钱序列(与硬币等值的金钱)作为其奖赏(或惩罚)。实验为2 (3枚一角硬币在序列首vs. 3枚一角硬币在序列尾)´2(先检查10元硬币序列vs. 先检查10.3元硬币序列)´2(损失vs. 获得)三因素设计, 每种条件随机分配15名商学院学生被试。结果表明, 被试倾向选择获益少(10元)和损失多(-10.3元)的金钱序列; 且获益大(10.3元)时高兴程度小, 损失小(-10元)时不高兴程度大。这一结果意味着：“聊”并不胜于“无”,反而是“无”胜于“聊”。其中, 伴随着违背价值最大化原则所产生的情感亦有悖逻辑。负性情感的引发一般有其“逻辑正确”的原因(如, 无惠而不乐); 而引发本研究负性情感的原因实属“逻辑错误”(如, 惠多而不乐)。这种不曾被定义而类似于“冤”的情感不仅见于个人,也见于民族、国家间的持续交往, 值得进一步研究。     

Group Cancellation and Resolution

We establish a connection between the geometric methods developed in the combinatorial theory of small cancellation and the propositional resolution calculus. We define a precise correspondence between resolution proofs in logic and diagrams in small cancellation theory, and as a consequence, we derive that a resolution proof is a 2-dimensional process. The isoperimetric function defined on diagrams corresponds to the length of resolution proofs.     

恶性肿瘤综合治疗的策略

肿瘤综合治疗是根据病人的机体情况以及肿瘤的病理类型、侵犯范围(病期)和发展趋向,将现有的手术治疗、放射治疗、化学治疗、生物治疗和中医中药治疗等各种手段有目的地、科学地、有计划地作一个序贯性的安排和实施,力争取得最佳的治疗效果。肿瘤的综合治疗是一个多学科协作的合理的新型模式。     

关于恶性肿瘤发病年轻化的思考

恶性肿瘤的发病多在50岁以后,以中老年人常见。近年发现青年(≤40岁)患癌有增高趋势。从恶性肿瘤的高危因素及分子机制方面,探讨恶性肿瘤发病年轻化的可能原因。辩证地剖析机体内部和外界环境之间的关系,是研究恶性肿瘤发病年轻化的重要环节。     

《史记·扁鹊仓公列传》的治疗学思想

《史记·扁鹊仓公列传》是记述扁鹊和仓公医事活动的专篇.目前,中医界大多集中在对其原文的医古文语言学分析、扁鹊和仓公医事活动年代的考证、所载病案的病因病机与诊法的探讨等方面,而专篇探讨扁鹊和仓公治疗学思想的研究尚缺,本文就此加以论述,并与《内经》简单地对照.
