降钙素原及T细胞亚群对急性脑梗死后感染的诊断价值研究

目的 研究降钙素原及T细胞亚群对急性脑梗死后感染的诊断价值.方法 选取2015年2月至2016年1月在该院进行诊治的急性脑梗死患者122例,根据患者脑梗死后是否发生感染分为感染组(60例)和未感染组(62例).分别对比两组入院时收缩压、舒张压、体温、美国国立卫生研究所卒中量表(NIHSS)评分,以及脑梗死发生部位,降钙素原、CD4、CD8水平,并进行Logistic回归分析.结果 感染组NIHSS评分为(14.9±5.7)分,明显高于未感染组的(10.6±3.8)分(P＜0.01).感染组脑桥梗死人数占比为35.48％,明显高于未感染组的17.74％ (P＜0.05).感染组降钙素原明显高于未感染组,而CD4、CD8水平则明显低于未感染组(P＜0.05).经多因素Logistic回归分析,影响急性脑梗死后感染的危险因素包括脑桥梗死、NIHSS评分、降钙素原、CD4及CD8水平.结论 临床工作中通过对急性脑梗死患者的降钙素原与T细胞压群进行检查,有利于预测感染的发生.

Study on diagnostic value of procalcitonin and T cell subsets in infection after acute cerebral infarction

Objective To study the diagnostic value of procalcitonin and T cell subsets in infection after acute cerebral infarction(ACI).Methods One hundred and twenty-two patients with ACI in our hospital from February 2015 to January 2016 were selected and divided into the infection group(60 cases) and non-infection group(62 cases) according to whether infection occurring.The systolic blood pressure,diastolic blood pressure,body temperature,NI H SS score,cerebral infarction location,procalcitonin,CD4 level,CD8 level were compared between the two groups.The Logistic regression analysis was performed.Results The NIHSS score in the infection group was (14.9 ± 5.7) points,which was significantly higher than (10.6-4-3.8) points in the non-infection group,the differences were statistically significant (P＜0.05).The number of pons infarction in the infection group accounted for 35.48 ％ (22/60),which was significantly higher than 17.74 ％ (11/62) in the non-infection group,the differences were statistically significant(P＜0.05).The procalcitoninl level in the infection group was significantly higher than that in the non-infection group,while the levels of CD4 and CD8 were significantly lower than those in the non-infection group,the differences were statistically significant (P＜0.05).The multivariate Logistic regression analysis showed that the risk factors affecting infection after cerebral infarction included pons infarction,NIHSS score,procalcitonin,CD4 and CD8 levels.Conclusion Detecting procalcitonin and T cell subsets in the patients with ACI in clinical work is conducive to predict the infection occurrence.
