“五指神功”赶走春困

春日的困顿是OL永远的尴尬。总不能隔着会议桌在老板的眼皮底下与周公相会吧。这时，我们的“五指神功”就该发挥作用了![编者按]     

氯化钾溶液配制方法的改进

目的考察配制方法的改进对氯化钾溶液质量的影响。方法采用留样观察方法,定期观察氯化钾溶液的性状外观,测定溶液pH值,羟苯乙酯含量及检查微生物限度。结果配制方法改进后制备的氯化钾溶液,经留样观察1年,外观始终保持无色澄明,溶液pH值、羟苯乙酯含量、微生物限度符合规定。结论改进工艺比按原工艺配制的氯化钾溶液质量稳定,改进的生产工艺值得推广。     

部分背阔肌皮瓣游离移植修复前臂背侧组织缺损并重建伸指功能

Objective To report the operative methods and clinical effects of free transfer of part of the latissinus dorsi flap for coverage of dorsal forearm composite tissue defects and reconstruction of extensor function. Methods Eleven cases of large-scale composite tissue defects of the dorsal forearm as a result of trauma were treated with partial latissimus dorsi flap The medial portion of the myoeutaneou flap containing the medial thoracodorsal nerve branch Was transferred to the defect on dorsal forearm.The thoracodorsal nerve in the flap was sutured either to the radial nerve deep branch or to the extensor comnunis muscle branch.The distal aponeurosis of the latissimus dorsi woven to the tendons of the 2nd to 4th digit extertsors.The size of the harvested flaps ranged from 21 cm×9 cm to 27 cm×13 cm. Results Postoperatively all 11 myocutaneous flaps survived.Three cases underwent trimming of the cutaneous flap or myocutaneous flap due to bulkiness.Two cases had tendon tighteing procedures due to laxity of the extensor tendon.Nine eases were followed up for 6 months to 3 years,while 2 cases were lost to follow up.The extensor strength returned grade Ⅲ in 2 cases,grade Ⅳ in 6 cases grade Ⅴ in 1 case.The limb function was mostly restored and the appearance was satisfactory.According to the upper extremity functional evaluation criteria issued by the Hand Surgery Society of Chinese Medical Association the results were rated as excellent in 2 cases,good in 5 cases,and fair in 2 cases.The overall excellent and good rate was 77.8%. Conclusion Partial transfer of the latissimus dorsi myocutaneous flap for coverage of dorearm forearm composite tissue defects and reconstruction of extensor function can not only achieve good treatment outcomes,but retain some of the latissimus dorsi function as well.     

青海不同民族地区学生肠道寄生虫感染调查

<正> 为落实《全国中小学生肠道蠕虫防治方案》,近年来,对我省西宁市、贵德县、乐都县、海晏县1982名中小学生,及本省汉、土、撒拉、回族3800名中小学生,进行了人群寄生虫感染情况调查。现将调查结果报道如下:1 调查对象与方法 调查对象为1市、3县所在地的中小学生1982名,其中中学生983名,小学生999名。汉族学生2000名,土族学生600名,撒拉族学生600名,回族学生600名。     

从蛋白质自组装的角度探析甘草附子配伍减毒机制

甘草与附子配伍有减毒增效的作用。该研究从中药汤剂甘草和附子混煎过程中蛋白质自组装的现象入手,以甘草蛋白和附子主要毒性物质——乌头碱为研究对象,探析甘草附子配伍减毒机制。研究发现经分离纯化后的甘草蛋白在p H 5时可通过自组装形成粒径为(206.2±2.02)nm的稳定颗粒,且可与乌头碱形成平均粒径为(238.20±1.23)nm的甘草蛋白-乌头碱稳定颗粒。通过小鼠急性毒性实验发现注射乌头碱单体的小鼠全部死亡,而注射相同乌头碱含量的甘草蛋白-乌头碱颗粒的小鼠全部存活。对甘草蛋白-乌头碱胶体颗粒的稳定性的调查显示,该胶体颗粒在室温下较稳定,具有成为候选药物载体的可能性。综上所述,甘草蛋白可通过与乌头碱自组装而达到减毒效果。     

胰腺癌伴梗阻性黄疸患者胆道感染高危因素分析

目的 分析胰腺癌伴梗阻性黄疸患者胆道感染分离菌及其高危因素.方法 回顾性分析65例胰腺癌伴梗阻性黄疸患者术中胆汁细菌培养及药敏结果,同时对患者年龄、胆道手术史、黄疸时间、CA199、胰头肿瘤大小、胆道梗阻部位、APACHEⅡ评分等因素与胆道感染的相关性进行研究.结果 胰腺癌梗阻性黄疸患者胆汁细菌培养阳性率为38.5％,其中肠杆菌科等革兰阴性菌占72.4％,对多数抗菌药物敏感;年龄＞60岁、既往胆道手术史、胆道梗阻部位和APACHEⅡ评分为5～8分,是上述患者胆道感染独立危险因素.结论 胰腺癌伴梗阻性黄疸患者胆汁培养以革兰阴性菌为主;高龄、既往有胆道手术史、胆道下段梗阻以及APACHEⅡ评分≥4分是胆道感染的独立危险因素,围手术期护理需特别关注.
