Comparison between a new platelet count drop method PL-11, light transmission aggregometry,VerifyNow aspirin system and thromboelastography for monitoring short-term aspirin effects in healthy individuals

Platelet function has been described by many laboratory assays, and PL-11 is a new point-of-care platelet function analyzer based on platelet count drop method, which counts platelet before and after the addition of agonists in the citrated whole blood samples. The present study sought to compare PL-11 with other three major more established assays, light transmission aggregometry (LTA), VerifyNow? aspirin system and thromboelastography (TEG), for monitoring the short-term aspirin responses in healthy individuals. Ten healthy young men took 100?mg/d aspirin for 3-day treatment. Platelet function was measured via PL-11, LTA, VerifyNow and TEG, respectively. The blood samples were collected at baseline, 2 hour, 1 day during the aspirin treatment and 1 day, 5?±?1 days, 8?±?1 days after the aspirin withdrawal. Moreover, 90 additional healthy subjects were recruited to establish a reference range for PL-11. Platelet function of healthy subjects decreased significantly 2 hours after 100?mg/d aspirin intake and began to recover during 4–6 days after the aspirin withdrawal. Correlations between methods were PL-11 vs. LTA (r?=?0.614, p?<?0.01); PL-11 vs. VerifyNow (r?=?0.829, p?<?0.01); PL-11 vs. TEG (r?=?0.697, p?<?0.001). There was no significant bias between PL-11 and LTA at baseline (bias?=?1.94%, p?=?0.804) using Bland-Altman analysis, while the data of PL-11 were significantly higher than LTA (bias?=?24.02%, p?<?0.001) during the aspirin therapy. The reference range for PL-11 in healthy young individuals was from 66.8 to 90.5% (95%CI). When aspirin low-responsiveness was defined as LTA?>?20%, the cut-off values for each method were, respectively: PL-11?>?50%, VerifyNow?>?533 ARU, TEG?>?60.2%. The results of different platelet function assays were uninterchangeable for monitoring aspirin response and correlations among them were also varied. Correlations among PL-11 and other three major assays suggested the ability of PL-11 to assess the treatment effects of aspirin. But a large cohort study is needed to confirm the cut-off value of aspirin response detected by PL-11.     

唐以前医籍中有关消渴病饮食服药宜忌探析

消渴病与饮食关系密切,关于消渴病发病及治疗过程中的饮食、服药宜忌古已有之。其思想发源于《内经》,具体论述始于《伤寒杂病论》,在魏晋南北朝时期的诸多医籍中不断积累完善,到了唐代《外台秘要》和《医心方》时已经比较成熟,能够自成体系。通过系统总结唐以前医籍所载关于消渴病饮食及服药宜忌内容,分析其内在规律,有助于扩展和加深对糖尿病饮食宜忌相关的学术研究。     

医学生人格特质与共情能力的相关性研究

目的  测评医学生的共情能力现状，探讨人格特质对其共情能力的影响,为培养医学生的共情能力提供对策。方法  以上海市3所高校临床医学专业学生为研究对象，采用班级整群抽样的方式进行问卷调研。采用杰斐逊共情量表-医学生版（JSPE-S）和大五人格量表（NEO-FFI）分别评估医学生的共情和人格特质。结果  共发放问卷2 020份，回收有效问卷1 958份，有效率为96.93%。医学生的共情能力总分均值为（103.24±14.35）。共情能力总分与大五人格中的“外向性”“开放性”“宜人性”“严谨性”维度呈显著正相关（r=0.154~0.406, P<0.01），与大五人格中的“神经质”维度呈显著负相关（r=-0.175, P<0.01）。分层回归结果表明：“共情重要性”和“大五人格”量表的5个维度进入回归方程。其中，人格因素占可解释方差变异量的16.2%（P<0.01）。结论  我国医学生的共情能力低于国外医学生，重视人格特质的塑造有助于提高其共情能力。     

2005 - 2014年中国老年人肺癌发病的时间趋势分析

目的 分析2005 - 2014年我国老年人肺癌发病的时间趋势，为我国肺癌的防控工作提供依据。方法 根据2008 - 2017年《中国肿瘤登记年报》中肺癌的相关数据，分析2005 - 2014年我国老年人肺癌的发病情况，并通过年度变化百分比（annual percentage change，APC）分析其时间变化趋势。结果 2005 - 2014年我国老年人肺癌的发病率呈上升趋势（APC = 0.71%，P＜0.05），其中农村老年人肺癌的发病率从198.9/105上升至250.7/105，上升趋势更明显（APC = 2.81%，P＜0.05），尤以农村老年女性肺癌发病率的上升趋势最为明显（APC = 5.26%，P＜0.05）。2005 - 2014年中国老年人肺癌的发病在60～64岁和65～69岁组呈上升趋势（APC分别为2.83%和2.04%，均P＜0.05），而在农村地区，老年人所有年龄组的肺癌发病率都呈明显上升趋势（APC分别为3.49%，3.86%，1.66%，2.31%，3.49%及6.37%，均P＜0.05）。结论 2005 - 2014年我国老年人肺癌发病上升趋势明显，以农村老年女性最为突出，国家应针对高危人群及早开展筛查等工作，降低我国老年人肺癌的流行水平。
