危急病患者表现出单细胞HLA-DR表达的减少,与疾病严重程度和全身炎症有关. 较高的APACHE II和CRP得分与较低的HLA-DR水平相关,表明免疫抑制增加.
科学领域:
- 免疫学 免疫学 免疫学
- 关键护理医学 关键护理医学
背景情况:
- 在ICU中的重症患者经历过渡性免疫抑制.
- 在单细胞上减少HLA-DR的膜表达 (MHLA-DR) 是这种免疫抑制的标记.
研究的目的:
- 在重症患者中确定与低MHLA-DR表达相关的因素.
- 分析百分比HLA-DR和MFI HLA-DR与患者严重程度和炎症标志物的关系.
主要方法:
- 包括84名没有先前免疫抑制的危急病患者.
- 使用APACHE II评分评估疾病严重程度和炎症,在入院时具有CRP水平.
主要成果:
- 较高的APACHE II和CRP得分与较低的百分比HLA-DR和MFI HLA-DR有关.
- 强大的线性回归显示了APACHE II/CRP和HLA-DR表达之间的显著反向关系 (p<0.05).
结论:
- 危急病患者的免疫抑制程度与全身炎症直接相关.
- 疾病的严重程度是影响免疫抑制程度的关键因素.

Critical Region, Critical Values and Significance Level
In hypothesis testing, a sample statistic is converted to a test statistic using z, t, or chi-square distribution. A critical region is an area under the curve in probability distributions demarcated by the critical value. When the test statistic falls in this region, it suggests that the null hypothesis must be rejected. As this region contains all those values of the...
