针刺对照激素治疗贝尔麻痹急性期疗效比较系统评价

目的：比较针刺与激素治疗贝尔麻痹急性期临床疗效及安全性。方法：检索PubMed、Cochrane图书馆、CBM数据库、CNKI数据库等收集针灸治疗贝尔麻痹急性期的临床随机对照试验,以Cochrane系统评价手册4.26结合Jadad进行质量评价,统计学分析采用RevMan 4.2.6。结果：4篇文献符合纳入标准,共316例患者。Meta分析显示针刺治疗贝尔麻痹急性期对照激素为主治疗,组间比较差异无统计学意义。合并RR[随机效应模型]=1.11,95%CI（0.99,1.25）,Z=1.80,P=0.07。结论：针刺较激素予贝尔麻痹急性期治疗治愈率尚无差异,但可能有缩短疗程的趋势,需要高质量的证据进一步证明。     

Influence of Varying Tensile Stress on Domain Motion

Magnetic domain motion has been widely studied in the fields of spintronics, nanowires, and thin films. However, there is a lack of such studies on industrial steels, especially for domain motion under the action of varying stress. Understanding domain motion under stress is helpful for the improvement of evaluation accuracy and the establishment of theoretical models of passive, nondestructive testing technology. This paper presents the influence of varying tensile stresses on the magnetic domain motion of silicon steel sheets. Magnetic domain rotation and domain wall displacement were characterized using magnetic domain images, and their motion mechanisms under elastic and plastic stresses are presented. The results show that the domain rotation under stress involves reversible and irreversible changes. The effect of material rearrangement on domain rotation and domain wall displacement after plastic deformation is discussed. Based on the motion mechanism, a threshold stress value (TSV) required for the complete disappearance of the supplementary domains in the elastic range is proposed, enabling the classification of the elastic stress ranges in which the reversible and irreversible domain rotations occur. In addition, the effect of microstructure on TSV is also discussed, and the results show that the regions far away from the grain boundary need larger stresses to complete an irreversible domain rotation. Additionally, the domain width and orientation also affect the TSV. These findings regarding the domain motion mechanism and TSV can help to explain the sequence of domain rotation under stress and modify the stress assessment under dynamic loads in electromagnetic nondestructive evaluation, especially in the magnetic memory method.

创建中国特色的器官获取组织质量管理体系

质量保证是器官获取组织(OPO)的责任,创建OPO质量管理体系是高质量开展人体器官捐献工作面临的新任务。当前我国OPO质量管理中存在着缺乏完善的管理机构、规范的管理流程、科学的评价指标、高素质的专业人才和浓厚的安全文化氛围等问题,有必要从思想观念转变、质量管理体系建设和过程实施管理等3个方面,紧密结合OPO的实际状况,参照国际通用质量管理体系标准进行顶层设计,更需要OPO管理者充分发挥领导作用,确保OPO在质量管理体系的持续改进中高效运行。     

Detailed evaluation of a newly attained fungal pigment from Monascus purpureus in meat burgers

Beef burgers with red pigment extracted from Monascus purpureus, used as a natural colouring agent, were examined for chemical compositions, physical properties, microbiological aspects and organoleptic evaluation. Beef burgers with Monascus pigment showed higher nutritional values compared with control samples. Nutritional values were proportionally enhanced by increasing pigment concentration. Synthetic dye samples had the lowest values of nutrients. Cooking loss percentage and water holding capacity were lower in all treatments compared with control samples, and vice versa for plasticity. The initial total bacterial count, Staphylococcus aureus count and coliform count were determined. Extending storage period up to 90 days severely reduced all tested microorganisms. By increasing the M. pigment concentration, the colour was significantly increased. Insignificant differences in colours were noticed among various treatments. Flavour and body and texture scores were insignificantly different. Microbial inhibition percentage of beef burger samples was increased by increasing the Monascus pigment concentration up to 0.8 g/kg.
