目的 :探索肺气虚证的本质。方法 :将 6 0只大鼠随机分为模型组与对照组 ,复制肺气肿肺气虚证模型 ,分别检测 pH、氧分压 (pO2 )、氧饱和度 (SaO2 % )、二氧化碳分压 (pCO2 )、白细胞介素 6 (IL 6 )、白细胞介素 8(IL 8)、肿瘤坏死因子 α(TNF α)及肺组织病理学的改变。结果 :模型组pH、pO2 、SaO2 %下降 ,pCO2 升高 ,与对照组比较 ,差异有显著性 (P <0 .0 1 ) ;模型组IL 6、IL 8、TNF α升高 ,与对照组比较 ,差异有显著性 (P <0 .0 1 ) ;病理组织学及超微结构检查显示肺组织有慢性支气管炎及肺气肿病变。结论 :肺气肿肺气虚证大鼠存在低氧血症和高碳酸血症 ,血中细胞因子IL 6、IL 8、TNF α升高 ,可能是肺气虚证从轻度向中、重度发展的重要原因之一。 相似文献

Sino-U. S. economic and trade relations as the most important and dynamic component of bilateral ties have evolved into the stabilizer, pillar and driving force for cementing the linkage between the two capitals. Their furtherance along the designated line of treating a "stake holder" and handling a "constructive partnership" will carry an ever-ballooning strategic significance even in diplomatic and security terms. Nevertheless the general trend looks set to be incessant progress amidst reciprocal accommodation in disregard of occasional twists and turns. 相似文献

Australian policy‐makers continue to rely on municipal amalgamation as the main engine of structural reform in local government, despite strong evidence that it diminishes participation and representation without improving service efficiency. Several promising, but neglected alternative models of structural reform have been developed, including ad hoc resource sharing models, Regional Organisations of Councils, virtual local government, and agency models. In an encouraging response to the recent policy of enforced council amalgamations in NSW, the Shires Association of NSW (2004) has recently proposed a ‘Joint Board model’ of local governance and invited comment on this model. This article takes up this challenge and seeks to place the Joint Board model in conceptual context and evaluate its characteristics and simulated cost savings. 相似文献

The present study investigated the extent to which psychosocial development through the first five stages of Erik Erikson's theory of personality development is associated with Diagnostic and Statistical Manual (third edition, revised; DSM-III-R) Axis II personality disorder symptomatology in a late adolescent sample of undergraduate students. The Inventory of Psychosocial Development (IPD) and the Personality Diagnostic Questionnaire—Revised (PDQ-R) were administered to a mixed-sex sample of 106 undergraduate students. The results of this research were that IPD scores assessing negative resolutions of the first five Eriksonian developmental stages consistently predicted scores on the PDQ-R composite scale and the PDQ-R impairment/distress index—both measures of overall personality disorder symptomatology. The IPD subscales varied substantially in the extent to which they predicted scores on the 13 PDQ-R subscales that assess symptoms of specific DSM-III-R personality disorders—ranging from the trust vs. mistrust subscale, which predicted scores on 12 of the 13 PDQ-R subscales, to the initiative vs. guilt subscale, which predicted scores on only 6 of the 13 PDQ-R subscales. Implications of these findings for our understanding of the relationship between psychosocial development and psychopathology are discussed in the context of previous research in this area, and suggestions for future research are offered.Received Ph.D. from Temple University.

Legal context. A recent High Court judgment, Fraser-WoodwardLimited v BBC and Brighter Pictures Limited, is of key interestto those that use or advise upon the use of copyright materialfor the purposes of criticism or review. Key points. This case involved the use of newspaper photographsof David and Victoria Beckham in a television documentary aboutthe relationship between celebrities and the press. The programmeillustrated its theme using screenshots of tabloid newspaperpages, which inevitably included a number of photographs. Theclaimant was the copyright holder in respect of a number ofthe photographs, and alleged that their reproduction in theTV programme was an infringement of copyright. The defendantssuccessfully relied upon the fair dealing and incidental inclusiondefences to copyright infringement. Practical significance. Although each fair dealing case willultimately turn on its own facts, Mann J gave a very usefulreview of the state of copyright law in this difficult area. 相似文献
