Methods: from March to August 2018, 80 healthy volunteers were admitted for physical examination. Two kinds of blood coagulation vacuum blood collection specimens were used for coagulation test. In group A, blood vessels were collected by BD coagulation vacuum, and in group B, anticoagulation tubes made in China were used. The influence of different time and temperature on coagulation test results was analyzed. Results: there was no significant difference in TT, FIB, APTT and Pt between the two groups (P > 0.05); after 8 hours of cryopreservation, TT, APTT and PT were higher than those of the immediate examination (P < 0.05); after 4 hours of room temperature preservation, TT, Pt and APTT were higher than those of the immediate examination (P < 0.05) There was no significant difference in FIB in room temperature, cryopreservation and instant examination (P > 0.05). Conclusion: different quality of vacuum collection vessels will affect the results of the examination, while the storage time and temperature will affect the results of the examination. In order to ensure the accuracy of the examination, we should select a suitable coagulation vacuum collection tube and complete the examination within 2 hours.

简介:摘要:某油田 S2层注水量噼分不合理,有效注水量难以确定,导致数值模拟结果误差较大。根据单井生产动态曲线,注水量,产液量,吸水剖面和液体产量剖面,采用动态循环分析法结合 Petrel- RE数值模拟技术确保了全区的拟合精度。该区拟合准确率为 98.59%,单井历史准确率为 90 .02%, S2层有效累计注水量为 2727 ×104m3,累计注采比为 1.2。应用此方法得出的剩余油储量分布与实际地层情况更接近,保证了后期方案预测和增产措施的准确性。
简介:摘要脓毒症是以宿主对感染反应失调为特征的可危及生命的临床综合征,为PICU收治患儿主要死亡原因之一。脓毒症时炎症、凝血反应相互促进,从而导致凝血功能障碍。脓毒症凝血功能障碍普遍存在,在多系统器官功能障碍(multiple organ dysfunction syndrome,MODS)的发生发展中起重要作用,对脓毒症的最终转归至关重要。脓毒症凝血功能障碍非单一途径驱动,内皮细胞、血小板、凝血因子等均起重要作用,故针对单一途径进行治疗难有良好效果。故该文对相关文献进行整理分析,对脓毒症凝血功能障碍发病机制、临床检测方法的研究进展进行综述,希望对临床寻找有效治疗方法及最佳干预时机提供参考。
