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.     

高热惊厥214例临床分析

本文分析了214例高热惊厥,结果为:检出率4.35％;男女之比为1.61:1;好发年龄为6个月～6岁(93.5％);首发年龄为6个月～4岁(89.9％);惊厥发作时体温多在39℃以上(74.6％);惊厥发作多在发热后12h内(72.4％);每次热病中惊厥发作1～3次(99.5％);惊厥持续时间多在15min内(91.0％);致惊厥发作的热性疾病以上呼吸道感染为最多;214例中63例复发,其中2例转癫痫,61例尚未发现智力低下或其他异常。从2例转癫痫的临床及脑电图看,提示惊厥发作愈重,持续时间愈长,转癫痫的可能性愈大。

核磁共振法测定非离子表面活性剂 HLB 值的研究 2.几种混合体系 HLB 值的测定与计算

本文应用核磁共振法(NMR)测定了几种混合体系的 HLB 值与混合体系中各组分的 HLB 值。实验结果表明,混合体系中各组分在核磁共振图谱中的积分曲线高度也具有加和性。混合体系的 HLB 值是体系中各组分 HLB 值的加权平均值。因此,对混合体系的 HLB 值可以应用 NMR 法直接测定,也可应用 NMR 法测定各组分的 HLB值,通过计算求得,计算值与实测值完全一致。

LightCycler实时监测PCR定量分析血清HBV DNA

目的 检验LightCycler实时监测PCR（real-time detection PCR,RTD-PCR)对血清中HBV DNA定量检测的灵敏性和可重复性，探讨HBV血清标志物与HBV DNA定量的关系。方法 HBV定量按深圳匹基公司乙肝PCR荧光检测试剂盒使用说明，对乙肝标志物已明确的773例血清中HBV DNA定量结果进行统计分析。结果 实时监测PCR对血清中HBV DNA定量检测的灵敏性高，可检测低至1000拷贝／ml血清；可重复性好，批间误差＜20％；各种标志物类型的血清HBV DNA含量分布情况表明，HBV血清标志物中HBeAg与HBV DNA含量有明显的关系，一般HBeAg阳性血清HBV DNA含量较高，但也有相当一部分例外。结论 LightCycler实时监测PCR对血清中HBV DNA定量检测灵敏性高可重复性好；仅根据HBV血清标志物往往不能确定乙肝患者HBV DNA复制水平的高低，HBV DNA定量检测具有十分重要的临床意义。
