目的:观察清胰通腑泻热饮对重症急性胰腺炎(SAP)患者外周血单核细胞 p38MAPK/核因子-κB(NF-κB)信号通路及下游炎症因子的影响并探讨其作用机制。方法:将 60 例患者随机分为对照组与观察组各 30 例。对照组给予西医常规治疗,观察组在对照组的基础上加用清胰通腑泻热饮,疗程均为 10 d。2 组分别在治疗第 1 天、第 11 天早晨 7 点抽血,采用 Westernblot 法测定外周血单核细胞 p38MAPK 和磷酸化 p38MAPK(p-p38MAPK)蛋白表达水平;酶联免疫吸附法(ELISA)测定肿瘤坏死因子-α(TNF-α)、白细胞介素-6(IL-6)、白细胞介素-8(IL-8)、NF-κB 水平。结果:观察组总有效率为 93.33%,高于对照组的 70.00% (P<0.05)。与同组治疗前比较,治疗后 2 组 p38MAPK、p-p38MAPK 蛋白表达及 TNF-α、IL-6、IL-8、NF-κB 水平均下降(P<0.05),且观察组低于对照组(P<0.05)。结论:SAP 患者外周血单核细胞 p38MAPK、p-p38MAPK 蛋白表达水平及 TNF-α、IL-6、IL-8、NF-κB 水平均升高;清胰通腑泻热饮可能通过下调 p38MAPK/NF-κB 水平抑制下游炎症因子的释放。
