目的 研究进展性脑梗塞与超敏 C-反应蛋白(hs-CRP)、纤维蛋白原(FIB)、血清胱抑素C(CysC)的相关性。方法 选择82例脑梗塞患者作为观察组,根据患者临床表现分为进展性脑梗塞组和非进展性脑梗塞组,另选择70例非脑血管病患者作为对照组;分别检测血清hs-CRP和FIB、CysC水平。结果 观察组患者血清hs-CRP和FIB、CysC含量较对照组升高(P<0.01);进展性脑梗塞组血清hs-CRP和FIB、CysC含量高于非进展性脑梗塞组(P<0.05)。经Spearman 相关分析发现,进展性脑梗塞组的血清hs-CRP、FIB、CysC水平与美国国立卫生研究院卒中量表(NIHSS)评定的神经功能缺损评分呈正相关。结论 血清hs-CRP、FIB、CysC水平检测有助于进展性脑梗塞患者的早期诊断,对预后有评估作用。

目的 探讨血浆D-二聚体及纤维蛋白原在社区获得性肺炎患者严重程度评估的应用价值。方法 收集110例社区获得性肺炎患者的临床资料,根据CURB-65评分标准对患者进行分组,分别测定患者血浆D-二聚体及纤维蛋白原水平,比较其在不同分组间的差异及通过ROC曲线了解其在重症社区获得性肺炎诊断中的价值。结果 不同CURB-65分组间D-二聚体、纤维蛋白原水平比较差异有统计学意义(P<0.05),重症肺炎组D-二聚体、纤维蛋白原水平明显高于非重症肺炎组(P<0.05)。ROC曲线显示入院D-二聚体、纤维蛋白原水平诊断重症肺炎曲线下面积(AUC)分别为0.815、0.777。结论 血浆D-二聚体及纤维蛋白原可以有效评估社区获得性肺炎患者病情的严重程度,其是诊断重症肺炎的一个良好指标。

Objective To evaluate the prediction and evaluation of plasma D-dimer and fibrinogen levels upon the severity of community acquired pneumonia(CAP). Methods Clinical variables of 180 patients with CAP were evaluated and divided into different groups by CURB65.Plasma D-dimer and fibrinogen were measured to compare their levels among different groups and evaluate the prediction in the diagnosis of the severe CAP by ROC curve. Results The mean D-dimer and fibrinogen level were different significantly among different CURB65 groups. D-dimer and fibrinogen level of severe CAP were significantly higher than non-serious pnrumonia group. The area under the curve of the D-dimer, fibrinogen in the diagnosis of severe pneumonia were 0.815, 0.777. Conclusion Plasma D-dimer and fibrinogen can effectively evaluate the severity of illness in patients with community acquired pneumonia and they could be useful for assessment of the severity of CAP.
