Outcome:

Related gene expression: TLR-2, MyD88, and NF-κB

Type:

Primary indicator

测量时间点:

入院48小时内

测量方法:

采集两组患儿外周静脉血,Ficoll 分层液法分离外周血单个核细胞,采用 RT-PCR 法检测 TLR-2、MyD88、NF-κBmRNA 基因表达水平;取两组患儿外周静脉血 4ml,离心分离血清,采用 ELISA法检测血清肿瘤坏死因子-α(Tumornecrosis factor,TNF-α)、白细胞介素-6(Interleukin-6,IL-6)、IL-8 水平。

Measure time point of outcome:

Within 48 hours of admission

Measure method:

Peripheral venous blood was collected from the two groups, and the peripheral blood mononuclear cells were isolated by Ficoll stratified solution, and the expression levels of TLR-2, MyD88 and NF-κBmRNA genes were detected by RT-PCR. Peripheral venous blood was collected from the two groups, and serum levels were separated by centrifugation, and serum levels of tumornecrosis factor (TNF-α α), interleukin-6 (IL-6) and IL-8 were detected by ELISA.
