Abstract:
Objective To explore the changes in inositol requiring enzyme 1 (IRE1),apoptosis signal regulating kinase 1 (ASK1) and c-Jun N-terminal kinase (JNK) mRNA levels in peripheral blood CD4+ T cells of children with acute paraquat (PQ) poisoning.Methods Blood samples of 30 cases of acute PQ poisoning (PQ group),who visited Tianjin Children's Hospital from June 2014 to June 2016,with 18 male and 12 female,aged from 2 to 14 years old,were collected,and the clinical and laboratory data were documented.Peripheral venous blood samples were collected after paraquat was taken.Thirty healthy children at the same age and of the same sex were selected as a healthy control group,18 male and 12 female,aged from 2 to 14 years old.CD4+ T cells in the peripheral blood were separated,and IRE1,ASK1 and JNK mRNA levels in peripheral blood CD4+ T cells were measured by real time polymerase chain reaction (Real-time PCR) method.Specificity of PCR products was validated through agarose gel electrophoresis.The data were statistically analyzed by SPSS 13.0 software.Results All of the 30 children had mucosal lesions,nausea,vomiting and abdomen pain,19 cases with oliguria and anuria,16 cases with alimentary tract bleeding,12 cases with headache and dizziness,11 cases with short of breath,dyspnea and difficult breathing,8 cases with convulsion,5 cases with jaundice.The IRE1,ASK1 and JNK mRNA levels in PQ group were significantly higher than those in healthy control group (1.70 ± 0.16 vs.1.02 ± 0.18,3.56 ± 0.85 vs.1.05 ± 0.31,5.22 ± 0.87 vs.1.01 ± 0.33,t =15.26,15.21,24.78,all P ＜ 0.01).Conclusions PQ increased the expressions of IRE1,ASK1 and JNK in peripheral blood CD4+ T cells,which may be related to PQ-induced oxidative stress and immune activation and lead to a complex cytokine network via endoplasmic reticulum stress and CD4+ T cell apoptosis and then results in the occurrence and development of multiple organ failure.
