小儿腹腔镜阑尾切除的临床疗效进展

急性阑尾炎是一种常见的、多发的外科疾病,在临床上认为早期手术能够有效治疗阑尾炎.在 19 世纪,开腹 式阑尾炎切除术被普遍认为是治疗阑尾炎的标准术式[1].但是,随着医学科技的发展,一位德国医生在 1983 使用腹腔 镜阑尾切除术取得一定成果以后,腹腔镜阑尾切除术便得到了关注与认可.腹腔镜阑尾切除术的优点有对患者伤害小、手术切口小且美观、术后恢复快、无不良反应等.本文主要针对小儿腹腔镜阑尾切除术的优点、临床疗效及其现状进行 总结.

目的探讨小儿阑尾炎行阑尾切除术后发生感染的原因及护理体会。方法 2009年1月～2011年12月本院对小儿阑尾切除术114例,有41例是患儿就诊时已经发生感染,其中21例合并腹膜炎,12例坏疽性阑尾炎,8例合并全身感染、发热、呕吐、嗜睡。结果经抗感染治疗和综合护理疗效满意。结论小儿阑尾炎较成人易发生穿孔合并腹膜炎,早期明确诊断,术中术后的正确治疗和护理可以提高小儿阑尾的治愈率。     

回盲部肿瘤并发生急性阑尾炎20例

目的就回盲部肿瘤并发生急性阑尾炎20例进行分析。方法选取2009年11月至2013年11月收治的20例回盲部肿瘤并存急性阑尾炎患者,手术过程中发现有16例患者由于并存阑尾炎故行右半结肠一期切除术,另外4例患者均为首次行手术切除阑尾,在手术后出现不同程度的黑便、血便、消瘦、腹痛等症状,在行电子结肠镜、钡灌肠或B超检查后再次手术。结果本组20例患者全部为回盲部结肠腺癌,有15例患者被诊断为阑尾炎,有1例患者术后出现阑尾残端炎:1例自动出院,3例好转,16例治愈。结论为了避免由于回盲部肿瘤并存急性阑尾炎而出现漏诊、误诊情况,应在术前对中老年阑尾炎患者进行详细、细致的全面检查,术中对患者的病情进行仔细探查,术后对患者后期状态进行随访。     

41例剖宫产合并子宫肌瘤切除术的临床分析

目的旨在对剖宫产合并子宫肌瘤病患进行临床切除术的可行性、安全性的探讨分析。方法将我院收治的82例剖宫产并子宫肌瘤病患分成合并手术组（41例）和剖宫产组（41例）;对两组病患相关数据进行分析。结果两组病患均顺利、成功完成手术,无一例并发症出现,同时,新生儿健康状况良好;两组间在平均手术用时、术后平均住院时间的差异无显著性;合并手术组术中平均出血量略高于剖宫产组,有差异。术后6个月后的随访中,两组均未发现子宫肌瘤复发。结论产妇于剖宫产的同时,应视病患具体实际情况可予以子宫肌瘤的切除,可有效避免二次手术所带来的痛苦及经济负担,具有较高的临床可行性及安全性。

John Stuart Mill's Theory Of Justice

John Stuart Mill has traditionally been portrayed as self-contradictory and failing to construct a unified social theory. Recent scholarship, however, has challenged this view, finding Mill's work to be creatively synthetic in bridging the antinomies inherent in liberal democratic thought. This revisionist interpretation of Mill is advanced by an understanding of his theory of justice and its role in shaping his policy positions on issues such as welfare, education, voting rights, property rights, taxation, government intervention, and the future of capitalism.

John Stuart Mill's Theories of Wealth and Income Distribution

Although he was much influenced by David Ricardo when he wrote the classical part of his Principles , John Stuart Mill was not a Ricardian when he penned his theories of wealth and distribution. They are based on a triple foundation. First, a belief that economics is a moral discipline. Second a theory of custom-driven human behavior. Third, an empirically formed conviction that the institutions of state, education and business cooperate to structure the distribution of income. On the basis of these presuppositions, Mill formulated 1) an institutional theory of the formation of human and non-human wealth and 2) an even more institutional theory of distribution demonstrating how the aforementioned institutions malignantly skew the distribution of income to the advantage of the propertied classes and to the extreme disadvantage of the working class. As a social economist, Mill recommended institutional reforms designed to eradicate the poverty of the working class.     

Toward a Phylogenetic Reconstruction of Organizational Life

Synopsis Classification is an important activity that facilitates theory development in many academic disciplines. Scholars in fields such as organizational science, management science and economics and have long recognized that classification offers an approach for ordering and understanding the diversity of organizational taxa (groups of one or more similar organizational entities). However, even the most prominent organizational classifications have limited utility, as they tend to be shaped by a specific research bias, inadequate units of analysis and a standard neoclassical economic view that does not naturally accommodate the disequilibrium dynamics of modern competition. The result is a relatively large number of individual and unconnected organizational classifications, which tend to ignore the processes of change responsible for organizational diversity. Collectively they fail to provide any sort of universal system for ordering, compiling and presenting knowledge on organizational diversity. This paper has two purposes. First, it reviews the general status of the major theoretical approaches to biological and organizational classification and compares the methods and resulting classifications derived from each approach. Definitions of key terms and a discussion on the three principal schools of biological classification (evolutionary systematics, phenetics and cladistics) are included in this review. Second, this paper aims to encourage critical thinking and debate about the use of the cladistic classification approach for inferring and representing the historical relationships underpinning organizational diversity. This involves examining the feasibility of applying the logic of common ancestry to populations of organizations. Consequently, this paper is exploratory and preparatory in style, with illustrations and assertions concerning the study and classification of organizational diversity.

Information infrastructure: Who builds broadband networks?

This paper examines the essential difference between the U.S. and Japan, when one considers information infrastructure. There are seven perception gaps between the U.S. and Japan concerning Information Infrastructure policies. These gaps must be understood in order to compare the countries' governmental policies in this area. In looking at the present circumstances, the essential question to answer concerns who is to build, own and operate the network(s) of the infrastructure. Liberalization is certain to be a central factor in the ongoing telecommunications debates. Now that customers have had a taste of the liberalized market-place, the movement toward more open markets will be difficult to stop. When considering options, it is necessary to pay close attention to standardized network access and the increasingly important role software plays. These issues are causing us to take a new approach to the traditional role played by regulators. They also force a closer look at the appropriate structure of utility companies. This paper addresses the above issues in hopes of stimulating dialog on the new telecommunications infrastructure paradigm.     

海岛地区产业演替及资源基础分析--以舟山群岛为例

改革开放以来,舟山市产业构成发生了显著变化,其经济发展过程可以划分为三个阶段。1992年前,是以产业结构渔业占绝对地位的单一结构阶段;1993—1998年,以旅游业为主的第三产业快速发展阶段;上世纪末以来,又进入了新一轮的经济发展时期,即工业产值比重快速增加阶段。根据海岛的自然资源基础和特点,在新世纪的经济发展过程中,舟山市应定位为生态型的港口旅游城市。以港口及临港工业为主导,以海岛旅游和海洋经济为特色,大力发展第二产业和第三产业。海岛地区的主导产业应体现海岛资源优势及区位优势,以集群性环保型产业为主。同时由于海岛地区淡水资源缺乏,主导产业也应着重选择低耗水型产业。
