采用腱鞘封闭治疗的方法治疗腱鞘炎及腱鞘囊肿存在引发肌腱无菌性坏死断裂的风险。通常由此引发的肌腱断裂能在早期被发现,但在一些特殊情况下肌腱断裂可能被漏诊,导致救治延迟。中国人民解放军32280部队医院于2022年2月收治一例患者,因多个原因共同导致环指伸肌腱尺侧支陈旧性断裂这一诊断漏诊。现本文回顾性分析该患者就医过程,并对相关文献进行复习总结,以期对类似疾病的诊疗提供参考和借鉴。

针对目前电梯设备维修方式盲目、维修成本高、效率低的问题,采用RCM理论对电梯设备维修决策进行研究。首先,从安全性、经济性、维修难易程度、检测难易程度四方面出发,综合考虑电梯设备维修方式影响因素,维修方式包括事后维修、视情维修和定期维修三种,利用层次分析法确定主观权重并结合模糊综合判断法建立设备维修方式决策模型。其次,基于设备寿命的威布尔分布,分别以维修费用最小和可用度最大为原则,建立了设备预防维修周期决策模型,并结合两个原则进一步优化最佳预防维修周期。最后,通过实例分析表明,上述方法能够对电梯设备维修方式和维修周期进行有效决策,进而为制定电梯RCM维修大纲提供理论依据。

Journal of Materials Science & Technology 2006年第6期22卷 855-859页

作者： Xinyu LU shihong ZHANG Hongliang HOU Jizhen LI Lixin zhou Zhiqiang LI Institute of Metal Research Chinese Academy of Sciences Shenyang 110016 China Beijing Aeronautical Manufacturing Technology Research Institute Beijing 100024 China

In this paper, the 3D elastic-plastic simulation was carried out by using finite element （FE） code according to the phenomena of flange keeping straight, bending towards headstock and bending towards tailstock in the shear spinning experiments for TC4 alloy. The simulation results for the three kinds of deformations of the flange agree well with the experimental results. So it is possible to explain the reason of flange bending by analyzing the strain vectors in the flange for the three kinds of deformation, which shows that it is important to apply the FE simulation technology for predicting the defects and optimizing the spinning process of TC4 alloys.

In this study, rat models of Parkinson＇s disease induced by substantia nigra injection of 6-hydroxy-dopamine were intragastrically administered Zhichan powder daily for 50 days. Reverse transcription PCR results showed that tyrosine hydroxylase mRNA expression in the rat substantia nigra was significantly increased, while monoamine oxidase B mRNA expression was significantly decreased in the Zhichan powder group, compared with the model group. In addition, the levels of striatal dopamine and homovanillic acid, the ratio of dopamine to homovanillic acid, and the activity of blood superoxide dismutase were all higher in the Zhichan powder group than in the model group but the content of malondialdehyde in blood was lower. Our experimental findings indicate that Zhichan powder has an antioxidant effect, it can regulate the expression of monoamine oxidase B and tyrosine hydroxylase in the substantia nigra of Parkinson＇s disease rats, and it can facilitate the secretion of striatal dopamine and its metabolite homovanillic acid.
