基于聚合酶链式反应-变性梯度凝胶电泳法的博物馆展厅空气细菌群落动态监测

目的了解博物馆展厅内空气中细菌数量和种类的动态变化。方法于2015年6月至2017年5月连续24个月在博物馆同一展厅同一位置进行空气微生物采样,采用培养法对空气微生物菌落总数进行检测,并进一步采用聚合酶链式反应-变性梯度凝胶电泳法(PCR-denaturing gradient gel electrophoresis,PCR-DGGE)对空气中细菌的组成种类进行分析。结果监测的两年间展厅空气中细菌数量有波动,菌落总数为78～616 CFU/m^3之间,主要种类有5～15种,种类变化存在季节性差异。马胃葡萄球菌(Staphylococcus equorum)、铜绿假单胞菌(Pseudomonas aeruginosa)、溶血性葡萄球菌(Staphylococcus hominis)、假单胞菌属(Pseudomonas sp.)在24个月内均有检出,且未随季节和人员的不同而变化。结论持续两年的监测显示博物馆展厅空气中细菌在种类和数量上呈现季节性变化,但已在一定程度上形成稳态。     

中国"人尸体标本展览"的伦理问题

自从德国解剖学家冯·哈根斯发明用于保存人尸体标本的生物塑化技术以来,一些西方国家相继举办了公开的"人尸体标本展览".这些带有明显的商业化和艺术色彩的"人尸体标本展览"在西方社会各界引起了广泛的伦理争论.近年来,在西方国家的影响下,中国以"科普展览"的名义也举办了"人尸体标本展览".这些展览与中国传统伦理观念发生了明显的道德冲突,在中国社会各界引起了一系列有关的伦理争论.本文从医学伦理学的角度出发,阐述了中国"人尸体标本展览"的有关伦理问题及其对策,并对生物塑化技术的应用的伦理问题进行了初步探索.     

替吉奥胶囊治疗进展期胃癌临床研究

[目的]以替加氟片为对照药,评价齐鲁制药有限公司生产的替吉奥胶囊联合奥沙利铂治疗进展期胃癌的安全性和有效性。[方法]实验组：替吉奥胶囊（80mg／m。）／d,分2次口服,d1-14。奥沙利铂,130mg／m^2,静脉滴注,d1。对照组：替加氟片（800mg/m^2）／d,分3次口服,d1-14。奥沙利铂130mg／m^2,静脉滴注,d1。3周为1个疗程。每例受试者至少进行2个周期的治疗方能进行疗效评价。[结果]替吉奥联合奥沙利铂治疗胃癌总有效率实验组33．3％、对照组25．0％,两组间比较差异无统计学意义（P〉0．05）。临床获益率实验组75％,对照组75％,两组间比较差异无统计学意义（P〉0．05）。试验组与对照组KPS评分改善差异无统计学意义（P〉0．05）。两组主要毒性反应为血液学毒性和消化道反应,两组间比较差异无统计学意义（P〉0．05）。[结论]替吉奥胶囊联合奥沙利铂是治疗进展期胃癌安全、有效的药物。     

Journey women: Art therapy in a decolonizing framework of practice

This paper presents the integration of art therapy in a decolonizing framework of practice used in a project called “Journey Women”. This framework of practice seeks to recognize and deconstruct the impacts of colonization and discrimination of First Nations, Inuit, and Métis peoples and to empower and inform people in their healing journey. “Journey Women” was an art exhibit of large-scale “body-map” images depicting the healing experiences of eight Aboriginal women, created in a three-day arts-based workshop. The collaborative research project between Minwaashin Lodge and Concordia University aimed to gain an understanding of the conditions that contribute or challenge Aboriginal women in their process of healing from violence and the impacts of violence. This paper describes the process of creating body-maps that integrated an art therapy framework with traditional Aboriginal ceremonies of prayer, smudging, drumming, and singing as well as movement and grounding activities, poetry, and art creation. In this article, we discuss how a public exhibit of body-maps acted as a powerful medium of empowerment, a forum for women to be witnessed by the community, and a means for Aboriginal women to act as their own agents of social change and social justice.     

上颌窦内侧壁缺损修补的临床观察

目的：探讨应用下鼻甲修补缺损的上颌窦内侧壁以观察临床效果。方法：采用下鼻甲骨折外展，分离下鼻甲粘膜作皮瓣。结果：15例中，修补成功13例，缺损消失；缺损范围缩小1例；缺损如前1例；总有效率为93．3％。结论：将下鼻甲骨折外展修补上颌窦缺损的内侧壁，安全系数大、创伤小，并使缺损的上颌窦回归原来的完整，避免了并发感染，减轻了患者因缺损丽导致的头部不适，提高了患者的生活质量。

Body Worlds exhibition—Visitor attitudes and emotions

BACKGROUND: Plastination is a new technique for odorless preservation of cadavers. Public exhibition of cadavers has raised controversy but attracted many people. METHOD: A total of 1078 visitors of the "Body Worlds" Exposition 2003 in Munich were surveyed about their emotional reactions, attitudes and health intentions to assess whether they learned more about human anatomy and aspects of health care. RESULTS: Most, 81.4% visited the exposition to learn more about anatomic structure and function of their own bodies, 86.4% considered this accomplished. Many, 49.8% visitors also felt disturbed. About 74.5% named curiosity as their motive. At least, 40.6% were led to reflect on their own mortality. In total, 42.6% resolved to pursue a healthier lifestyle. CONCLUSION: The "Body Worlds" Exposition teaches medical staff and lay people more about human anatomy, as well as the transience of life. About 94.3% visitors pleaded against prohibiting the exposition. The Body Worlds exhibition could improve its reputation if more information and incentives for health care were provided.
