被动吸烟对小鼠免疫功能的影晌

本文对被动吸烟的小鼠体内腹腔MΦ的吞噬功能和SRBC的体液免疫应答功能的变化情况进行了研究。用万能显微镜观测了腹腔MΦ,计算其吞噬率、吞噬指数和消化能力;用分光光度计检测了溶血素水平。结果证明,实验组小鼠噬腔MΦ的吞噬率。吞噬指数与消化能力均较不吸烟鼠显著降低(P<0.01),吸烟与不吸烟鼠间的血清半数溶血值也有非常显著差异(P<0.01)。实验说明,侧流烟雾对小鼠腹腔MΦ及抗体形成功能均有抑制作用。     

似然比和受试者工作特征曲线在评价铁参数对铁缺乏症诊断中的应用

目的评价几种铁参数在铁缺乏症诊断中的价值。方法连续性收集９０例贫血病人（缺铁性贫血３６例,慢性病贫血２３例,慢性病伴缺铁性贫血３１例）,做骨髓铁染色、血清转铁蛋白受体（ｓＴｆＲ）、血清铁蛋白（Ｓｅｒｕｍｆｅｒｉｔｉｎ,ＳＦ）、血清铁（Ｓｅｒｕｍｉｒｏｎ,ＳＩ）、总铁结合力（Ｔｏｔａｌｉｒｏｎｂｉｎｄｉｎｇｃａｐａｃｉｔｙ,ＴＩＢＣ）、转铁蛋白饱和度（Ｔｒａｎｓｆｅｒｉｎｓａｔｕｒａｔｉｏｎ,ＴＳ）等检查,应用似然比（ＬＲ）和受试者工作特征（ＲＯＣ）曲线分析方法,以骨髓铁染色作为金标准对以上的铁参数诊断慢性病合并缺铁性贫血的价值进行分析。结果在判断慢性病是否合并缺铁性贫血时ＳＦ在２５～４４μｇ／Ｌ时的ＬＲ最大（５８）,ｓＴｆＲ＞５０ｎｍｏｌ／Ｌ时的ＬＲ最大（６０）;ＲＯＣ曲线下面积以ｓＴｆＲ最大（０８４）,其他依次是ｓＴｆＲ／ｌｏｇＳＦ（０．８３）、ＳＦ（０７７）、ｓＴｆＲ／ＳＦ（０．７４）、ＳＩ（０７２）、ＴＩＢＣ（０６８）。结论认为ＲＯＣ曲线与ＬＲ对科学评价铁参数诊断价值有重要的意义,研究结果对于临床诊断具有重要的参考价值     

Changes of neurobehavioral and sensory functions due to toluene exposure below 50ppm?

Data of a follow up study with four examinations were summarized by odds ratio statistics in order to scrutinize the results of the earlier studies with cross sectional approaches.

For a “high”- (n = 106) and a “low”-exposed group (references, n = 86) current toluene exposures of 26 ppm versus 3 ppm and lifetime weighted average exposures of 45 ppm versus 9 ppm were ascertained. As measures of sensory functions vibration thresholds, colour discrimination, and auditory thresholds were used. Measures of psychological performances were attention (symbol–digit substitution, switching attention, simple reaction), memory (digit span forward, delayed reproduction of pictures), and psychomotor functions (steadiness, line tracing, aiming, tapping, peg board). Additionally, the frequency of diseases and symptoms were ascertained.

By odds ratio statistics including relevant cofactors no significant increase of “cases with impaired functions” among the high-exposed workers was found. Evidence for neurobehavioral effects due to long-term toluene exposure below 50 ppm was not established.     

The Impact of Patient Access to Their Electronic Health Record on Medication Management Safety: A Narrative Review

IntroductionAs the American’s Federal Health Insurance Portability and Accountability Act (HIPAA) stated that patients should be allowed to review their medical records, and as information technology is ever more widely used by healthcare professionals and patients, providing patients with online access to their own medical records through a patient portal is becoming increasingly popular. Previous research has been done regarding the impact on the quality and safety of patients’ care, rather than explicitly on medication safety, when providing those patients with access to their electronic health records (EHRs).AimThis narrative review aims to summarise the results from previous studies on the impact on medication management safety concepts of adult patients accessing information contained in their own EHRs.ResultA total of 24 studies were included in this review. The most two commonly studied measures of safety in medication management were: (a) medication adherence and (b) patient-reported experience. Other measures, such as: discrepancies, medication errors, appropriateness and Adverse Drug Events (ADEs) were the least studied.ConclusionThe results suggest that providing patients with access to their EHRs can improve medication management safety. Patients pointed out improvements to the safety of their medications and perceived stronger medication control. The data from these studies lay the foundation for future research.
