作者： minglu qi Jingping Yang Xue Yin Si Chen Xiyuan Xu The Third Affiliated Hospital of Inner Mongolia Medical University BaotouInner MongoliaChina

Objective:To explore the relationship between the expression of TLR4 and TIRAP and sepsis ***:The study selected 30 healthy examinees as the control group and 53 patients with sepsis as the observation *** patients in the observation group were assessed by Acute Physiology and Chronic Health Evaluation Ⅱ(APACHE Ⅱ).40 patients with APACHE Ⅱ score≤20,were classified into the low-score sepsis group;13 patients with APACHE Ⅱ score>20,were classified into the high-score sepsis *** levels of TLR4 and TIRAP in venous serum were detected in all subjects by enzyme-linked immunosorbent assay(ELISA).Results:The levels of TLR4 and TIRAP in serum were 0.886±0.058 ng/ml and 5.216±0.410 ng/ml in the control group;2.253±0.379 ng/ml and 9.540±2.294 ng/ml in the low-score sepsis group;4.494±0.709 ng/ml and 19.206±1.755 ng/ml in the high-score sepsis *** observation group(low-score and high-score sepsis groups)was significantly different from the control group(p=.000),and the low-score sepsis group was significantly different from the high-score sepsis group(p=.000).With APACHE II score of 20 as the cut-off point,the low-score sepsis group was consisted of low-risk patients and the high-score group was consisted of the high-risk,which can indicate the sepsis *** to Pearson’s correlation analysis,the level of TLR4 was positively correlated with sepsis severity(r=0.931,p<.05),the level of TIRAP was also positively correlated with the sepsis severity(r=0.972,p<.05);the level of TLR4 was positively correlated with the level of TIRAP(r=0.936,p<.05).Conclusions:The levels of TLR4 and TIRAP in septic patients can be used to predict and determine the severity of sepsis.
