摘要

目的 探究血必净对重症肺炎(SP)大鼠的影响及可能机制。 方法 40只SP大鼠随机分为模型组、微小RNA(miR)-155激动剂组(miR-155激动剂80 mg/kg)、血必净低剂量组(血必净注射液4 mg/kg)、血必净高剂量组(血必净注射液8 mg/kg)、miR-155激动剂+血必净组(miR-155激动剂80 mg/kg,血必净注射液8 mg/kg),各8只。8只健康大鼠分为对照组。对照组与模型组尾静脉注射等量生理盐水。连续给药7 d后,检测各组肺系数(LI),白细胞介素-1β(IL-1β)水平,受体酪氨酸激酶2(JAK2)、信号转导和转录激活因子1(STAT1)蛋白表达情况。 结果 与模型组比较,miR-155激动剂组LI、IL-1β水平及肺组织p-JAK2/JAK2、p-STAT1/STAT1升高,血必净低、高剂量组及miR-155激动剂+血必净组LI、IL-1β水平及肺组织p-JAK2/JAK2、p-STAT1/STAT1均降低(P < 0.05);与miR-155激动剂组比较,血必净低、高剂量组及miR-155激动剂+血必净组LI、IL-1β水平及肺组织p-JAK2/JAK2、p-STAT1/STAT1均降低(P < 0.05);与血必净低剂量组比较,血必净高剂量组LI、IL-1β水平及肺组织p-JAK2/JAK2、p-STAT1/STAT1升高(P < 0.05);与血必净高剂量组比较,miR-155激动剂+血必净组LI、IL-1β水平及肺组织p-JAK2/JAK2、p-STAT1/STAT1升高(P < 0.05)。 结论 血必净可减轻SP大鼠肺损伤,可能通过抑制miR-155表达进而降低JAK2/STAT1信号通路发挥作用。

Abstract

Objective To investigate the effect of Xuebijing on rats with severe pneumonia (SP) and its possible mechanism. Methods Forty SP rats were randomly divided into model group, miRNA-155 agonist group (miRNA-155 agonist, 80 mg/kg), Xuebijing low-dose group (Xuebijing injection, 4 mg/kg), Xuebijing high-dose group (Xuebijing injection, 8 mg/kg), miR-155 agonist + Xuebijing group (miR-155 agonist 80 mg/kg, Xuebijing injection 8 mg/kg), with 8 rats in each. Eight healthy rats were included into control group. Control group and model group were injected with the same amount of normal saline through caudal vein. After 7 days of continuous administration, lung coefficient (LI), interleukin-1β (IL-1β) level, receptor tyrosine kinase 2 (JAK2), signal transduction and transcriptional activator 1 (STAT1) protein expression were detected in each group. Results Compared with those in the model group, the level of LI and IL-1β, p-JAK2/JAK2 and p-STAT1/STAT1 in lung tissue were increased in miR-155 agonist group (P < 0.05). The level of LI and IL-1β, P-JAK2 /JAK2 and P-Stat1/STAT1 in lung tissue were decreased in low and high dose Xuebijing group and miR-155 agonist + Xuebijing group (P < 0.05). Compared with those in miR-155 agonist group, the level of LI and IL-1β, P-JAK2 /JAK2 and P-Stat1/STAT1 in lung tissue were decreased in Xuebijing low and high dose group, and miR-155 agonist + Xuebijing group (P < 0.05). Compared with those in Xuebijing low dose group, the level of LI, IL-1β, p-JAK2/JAK2 and p-STAT1/STAT1 in lung tissue were increased in Xuebijing high dose group (P < 0.05). Compared with those in Xuebijing group, LI and IL-1β level, P-JAK2 /JAK2 and P-Stat1 /STAT1 in lung tissue were increased in miR-155 agonist + Xuebijing group (P < 0.05). Conclusion Xuebijing can reduce lung injury in SP rats, possibly by inhibiting the expression of miR-155 and thereby reducing the JAK2/STAT1 signaling pathway.
