Objective:To analyze the application of PDCA mode in the management of blood transfusion waiting time.Methods:Using random block design, 98 patients received blood transfusion during January to December 2018 were included into the before improvement; 32 patients received blood transfusion during January to June 2019 were included into the after improvement. Standard process of blood taking and transfusion was applied to the before improvement, while based on standard process, found out the deficiencies in the previous clinical practice, continuously improved the details of the process for the after improvement. Then blood transfusion waiting times were compared between the two groups.Results:The blood transfusion waiting time was (26.95±9.20) min before improvement and (25.59±4.16) min after improvement, with a significantly lower disqualification rate 6.25% (2/32) comparing with 26.53% (26/98) before improvement. The differences were statistically significant ( t value was 3.75, P<0.01; χ2 value was 5.87, P<0.05). Conclusions:The application of PDCA circulation management mode can shorten the blood transfusion waiting time and transfusion can be made within 30 minutes after blood taking so that nursing quality of transfusion in the ward can be improved.

目的探索托珠单抗治疗类风湿关节炎，预防其不良反应的有效护理干预手段。方法将我院在2013年5月~2015年6月收治的188例类风湿关节炎患者作为研究对象，为所有患者采用托珠单抗进行治疗。将其随机分为观察组和对照组，每组94例。对照组配合常规的护理干预进行干预指导，观察组患者配合预见性护理干预模式进行干预指导，比较两组患者的护理效果。结果观察组患者的护理有效率为92.55%，对照组患者的护理有效率为73.40%，<0.05；观察组患者不良反应发生率为5.32%，对照组为28.72%，<0.05；观察组患者的满意度更高，<0.05，具有统计学意义。结论临床上采用托珠单抗治疗类风湿关节炎配合预见性护理对患者进行干预指导，效果更为显著，能够提高护理有效率，降低患者不良反应的发生率，值得推广使用。

Purpose To investigate the imaging features of breast phyllodes tumor on mammography(MG),ultrasound(US)and pathology,correlated with its clinical manifestation.Materials and Methods Twelve cases of pathologically confirmed breast phyllodes tumors were examined by US and MG.The imaging findings were retrospectively analyzed.Results Of the 12 cases of breast phyllodes tumors,6 were benign,3 were malignant and 3 were borderline.MG predicted 3 breast phyllodes tumors,3 breast carcinomas and 6 adenomas.US predicted 2 phyllodes tumors,8 breast masses and 2 adenomas.Conclusion The imaging findings of phyllodes tumors on MG and US are characteristic but not specific.Combined application of both US and MG are helpful for early detection but can not differentiate its malignancy which is determined by pathology.

为观察日本富士计算机X线摄影系统（FCR）在鼻外伤患者鼻骨骨折诊断中的作用，我们对比 分析了1999年9月至12月85例鼻外伤患者的鼻骨侧位CR片及相同部位的普通X线平片，现报告 如下。

目的评价计算机X线成像技术(CR)系统在乳腺成像中的应用价值。方法我们对42位女性患者双侧84例乳腺进行CR检查，并与传统X线检查结果对照。结果 CR检查检出乳腺正常者30例，乳腺增生者48例，良性占位者1例，检出率与传统X线平片无差异；但在5例乳腺癌中有3例在传统X线片未能确诊；CR在显示乳腺层次及微小病变及降低X线照射剂量方面优于传统X线片。结论乳腺CR成像技术是一种值得进一步推广使用的X线检查新技术。
