火药烟雾致支气管上皮细胞损伤及葛根素的干预研究

火药烟雾致支气管上皮细胞损伤及葛根素的干预研究摘要：

目的：本研究旨在探讨火药烟雾对支气管上皮细胞的影响及葛根素在其中的干预作用。

方法：采用原代培养的支气管上皮细胞，建立火药烟雾诱导的损伤模型，以CCK-8法检测细胞活力，使用RT-PCR和Westernblot检测各种蛋白的表达，观察葛根素在火药烟雾致损伤中的作用。

结果：火药烟雾诱导的损伤模型建立成功，并可重复多次。与对照组相比，火药烟雾组细胞活力显著降低，支气管上皮细胞中IL-6、TNF-α、ICAM-1、VCAM-1等炎性因子表达明显增强，同时JNK、p38、STAT3等信号通路活性显著升高。添加葛根素后，火药烟雾组细胞活力得到显著提升，炎性因子表达水平明显下降，信号通路活性也得到明显抑制。

结论：火药烟雾可引起支气管上皮细胞的损伤，激活炎性因子和信号通路，葛根素可通过调控炎性反应和信号通路，减轻火药烟雾对支气管上皮细胞的损伤。

Objective:Thisstudyaimstoinvestigatetheeffectofgunpowdersmokeonbronchialepithelialcellsandtheinterventionofpuerarininthisprocess.

Methods:Primaryculturedbronchialepithelialcellswereusedtoestablishagunpowdersmoke-inducedinjurymodel.ThecellviabilitywasdetectedbytheCCK-8method,andtheexpressionofvariousproteinswasdetectedbyRT-PCRandWesternblot.Puerarinwasusedtoobserveitsinterventioneffectingunpowdersmoke-inducedinjury.

Results:Thegunpowdersmoke-inducedinjurymodelwassuccessfullyestablishedandcouldberepeatedmultipletimes.Comparedwiththecontrolgroup,thecellviabilityinthegunpowdersmokegroupwassignificantlydecreased,andtheexpressionofinflammatoryfactorssuchasIL-6,TNF-α,ICAM-1,andVCAM-1inbronchialepithelialcellswassignificantlyincreased.Atthesametime,theactivityofJNK,p38,STAT3andothersignalingpathwayswassignificantlyincreased.Afteraddingpuerarin,thecellviabilityinthegunpowdersmokegroupwassignificantlyimproved,theexpressionofinflammatoryfactorswassignificantlyreduced,andtheactivityofsignalingpathwayswasalsosignificantlyinhibited.

Conclusion:Gunpowdersmokecancausedamagetobronchialepithelialcells,activateinflammatoryfactorsandsignalingpathways,andpuerarincanalleviatethedamagetobronchialepithelialcellsbyregulatinginflammatoryreactionsandsignalingpathways.
