摘要:

目的 观察超短波疗法对脂多糖诱导的大鼠急性肺损伤炎症反应的效果,以及对核苷酸结合寡聚化结构域样受体蛋白3 (NLRP3)信号通路的影响。
方法 3月龄Sprague-Dawley雄性大鼠24只随机分为对照组、急性肺损伤组和超短波组,每组8只。后两组气管内滴注脂多糖复制急性肺损伤模型,超短波组在造模后即刻、4 h、8 h予超短波干预15 min。造模后24 h处死动物,测量肺组织湿/干重比(W/D);HE染色评估损伤程度;ELISA检测白细胞介素(IL)-1β和IL-18水平;逆转录聚合酶链反应和Western blotting检测NLRP3、caspase-1和IL-1β mRNA和蛋白表达。
结果 急性肺损伤组肺组织W/D较对照组升高(P < 0.05),超短波组较急性肺损伤组有降低趋势,但无显著性差异( P > 0.05)。急性肺损伤组肺损伤评分较对照组增高( P < 0.05),超短波组较急性肺损伤组降低( P < 0.05)。急性肺损伤组血清IL-1β和IL-18水平均较对照组升高( P < 0.05),超短波组较急性肺损伤组降低( P < 0.05)。NLRP3、caspase-1和IL-1β mRNA和蛋白表达,急性肺损伤组均较对照组增高( P < 0.05),超短波组较急性肺损伤组降低( P < 0.05)。
结论 超短波疗法能抑制大鼠急性肺损伤的炎症反应,可能与抑制NLRP3/caspase-1/IL-1β信号通路有关。

Abstract:

Objective To observe the effects of ultrashort wave (USW) on lipopolysaccharide (LPS) induced acute lung injury (ALI) and nucleotide-binding oligomerization domain like receptor protein 3 (NLRP3) signaling pathway in rats.
Methods Twenty-four three-month-old male Sprague-Dawley rats were randomly divided into control group (n = 8), ALI group (n = 8) and USW group (n = 8). The ALI and USW groups were instilled with LPS to induce ALI, and the USW group was treated with ultrashort wave 0, four and eight hours after instillation, 15 minutes a time. Twenty-four hours after instillation, the lung tissue of the rats was measured the wet/dry mass ratio (W/D), and observed under HE staining. Serum levels of interleukin (IL)-1β and IL-18 were detected with ELISA. The mRNA and protein expression of NLRP3, caspase-1 and IL-1β in the lung tissue were detected with reverse transcription polymerase chain reaction and Western blotting, respectively.
Results W/D increased in ALI group compared with that of the control group (P < 0.05), and it decreased in USW group without significance compared with that of ALI group ( P > 0.05). Lung injury score increased in ALI group compared with that of the control group ( P < 0.05), and it decreased in USW group compared with that of ALI group ( P < 0.05); as well as the serum IL-1β and IL-18, and mRNA and protein expression of NLRP3, caspase-1 and IL-1β.
Conclusion USW can alleviate the inflammatory of acute lung injury, which may associate with inhibiting of NLRP3 signaling pathway.

Key words: acute lung injury, ultrashort wave, inflammatory, nucleotide-binding oligomerization domain like receptor protein 3, signaling pathway, rats
