弧菌,气单胞菌及邻单胞菌编码鉴定研究

采用编码技术对医学常见的弧菌属、气单胞菌属及邻单胞菌属的１２ 个菌种进行编码,建立了７ 位数编码鉴定法。并用此法鉴定了２０８ 株标准菌株,与常规鉴定法比较,两法无显著统计学意义（χ２ ＝０－４４ ,Ｐ＞０－０５）,符合率为９５－６７％ 。此鉴定法快捷、可靠、操作简便、判定结果简单、适合于临床、卫生及基层微生物实验室推广应用。     

LC/MS鉴定中药三七及其复方制剂

目的建立中药三七及其在复方丹参制剂中的特征图谱。方法用LC/MS分析方法,采集三七、人参和西洋参的LC/MS总离子流色谱,从总离子流色谱中提取三七主要化学组分的提取离子流色谱,选择相对稳定、3种药材间差异显著的提取离子流色谱作为三七药材的特征图谱。在相同条件下对比复方丹参的提取离子流色谱与三七的特征图谱;同时用LC/MS/MS对三七中的主要组分进行定性分析。结果与人参皂苷Rg1(m/z 800)和Re(m/z 946)具有相同m/z的提取离子流色谱在3种药材间差异显著,稳定可靠,在复方中有较好的重现性,复方丹参中其他共有成分对其无显著影响。结论三七的LC/MS特征图谱可作为鉴定复方丹参中三七的特征,也可作为鉴别三七和同属其他药材的特征。     

从"胎儿写真"谈对非医学需要的胎儿性别鉴定控制

通过“胎儿写真”的社会现象．首先介绍我国胎儿性别鉴定的法律制度，进而分析了严格禁止非医学需要胎儿性别鉴定的原因。最后，针对目前非医学需要胎儿性别鉴定得不到有效控制的现实，提出了采取控制措施的建议。     

藤茶叶的扫描电镜鉴别研究

目的为准确鉴别药用藤茶的来源提供依据.方法对藤茶主要药用部位叶及叶柄进行了扫描电镜研究.结果叶上表面角质层厚、多非腺毛,下表面角质层纹理沿细胞壁方向延伸,叶横切面可见大型分泌腔,叶柄表面有稀疏非腺毛及细纵纹.结论电镜方法快速准确,尤以角质层纹理、表面非腺毛的鉴别特征特异性强.     

品管圈活动降低儿科血液肿瘤病房响铃频次

目的 探讨品管圈活动在降低儿科血液肿瘤病房响铃频次的作用.方法 成立品管圈,确立＂降低病房响铃次数＂为活动主题,进行现状把握,目标设定,要因分析及对策制定和实施.结果 病房响铃频次由改善前的335次/周,降低至改善后的79次/周,护士人际沟通、团队精神、工作主动性等有明显提升.结论 品管圈活动对降低儿科血液肿瘤病房响铃频次效果显著.     

“胎数落”病因病机及针灸诊疗思路探析

现代中医学认为复发性流产相当于中医学中的"滑胎""胎数落"。但我们在探究复发性流产的中医学病名起源中发现,"滑胎"一词最早的含义与当今所指的复发性流产不同,"滑胎"在清乾隆四年以前实为临产催生的方法,而"数堕胎""胎数落"才更接近复发性流产的含义。历代中医对"胎数落"在发病原因及发病机制方面的认识上有寒热之分、虚实之别,各有千秋,自成体系,尤其对自然流产频率的连续性即"应期而落"这一特点的认识相当精确。针灸在治疗"胎数落"时须做到明辨虚实,虚则益气血、补脾肾、调冲任,实则活血化瘀兼以理气通经。     

Repair of a Cracked Historic Maryan Bell by Gas Welding

In this article, the range of works connected with the repair of a historical Maryan bell from 1639 are presented. The first attempts to repair damaged bells occurred in the 1930s in Poland. However, this process was stopped because of extensive technological difficulties. Welding and soldering-welding were the basic methods. There is one difference between these two methods—connecting surfaces are melted during the welding process but only heated until the melting temperature of the material added to the connection (that is the solder) during the soldering-welding process. It was important to heat the bell to the proper temperature during welding. Uneven heating causes the enlargement of existing cracks or the appearance of new ones, or even the complete destruction of the bell. Nowadays, a method of even heating using a special heating mat has been devised. Thanks to this method it is possible to control the heating and cooling process. The most important task during the whole operation of bell welding was obtaining the original sound. During this research, the chemical composition was examined to prepare a welding rod with a suitable chemical composition. After the repair process, an analysis of the sound of the bell was conducted. It was shown that the repair of bells is possible when correct thermal parameters are used. The most highly recommended technique for repairing bells is gas welding.
