摘要:
目的:探讨清解化攻汤对急性胰腺炎(AP)大鼠肠黏膜屏障及血清炎症因子的干预作用。方法:24只SD大鼠随机分成假造模组、模型组、西药组及中药组,每组各6只,运用雨蛙素联合脂多糖腹腔注射建立大鼠AP模型,成模后按分组给予相应药物干预,观察回肠组织的病理改变情况; 检测血清淀粉酶、肿瘤坏死因子-α(TNF-α)、白细胞介素-1β(IL-1β)、白细胞介素-10(IL-10)、D-乳酸及内毒素水平; Western blot检测回肠组织紧密连接蛋白Occludin的表达情况。结果:与假造模组比较,模型组回肠组织病理损伤明显,回肠黏膜绒毛略不规整或破损,肠上皮下间隙稍见增宽,与固有层分离增大,局部炎性细胞浸润增多,内皮下及固有层充血及出血明显增多,模型组血清淀粉酶、TNF-α、IL-1β、IL-10、D-乳酸及内毒素水平明显升高(P<0.01),回肠组织Occludin蛋白相对表达量明显下降; 与模型组比较,西药组和中药组病理改变明显减轻,血清淀粉酶、TNF-α、IL-1β、D-乳酸及内毒素水平均明显下降(P<0.01),血清IL-10及回肠Occludin蛋白相对表达量均明显增高(P<0.01); 与西药组比较,中药组血清淀粉酶、D-乳酸及内毒素水平降幅更明显(P<0.05)。结论:清解化攻汤对AP大鼠的肠黏膜屏障有一定的保护作用,而且该方可降低血清促炎细胞因子水平,提高抑炎细胞因子水平,对AP大鼠血清炎症因子有明显的调控作用。
Abstract:
Objective:To study the intervention effect of Qingjie Huagong decoction on intestinal mucosal barrier and serum inflammatory factors in acute pancreatitis(AP)rats.Methods:A total of 24 SD rats were divided into 4 groups in random including a fake model group,a model group,a western medicine group and a Chinese medicine group,with 6 rats in each group.The rat AP model was established by intraperitoneal injection of cerulein combined with lipopolysaccharide and immediately after the mold was formed,corresponding drug interventions were given in groups.The pathological changes of ileum tissue were observed.Serum amylase,TNF-α,IL-1β,IL-10,D-lactic acid and endotoxin levels were detected.Western blot was used to detect the expression of tight junction protein Occludin in ileum tissue.Results:In contrast with the fake model group,the model group showed more obvious pathological damage to the ileum tissue,slightly irregular or damaged ileal mucosal villi,slightly widened intestinal subepithelial space,increased separation from the lamina propria,increased local inflammatory cell infiltration and the subendothelial and lamina propria congestion and bleeding increased significantly.The serum levels of amylase,TNF-α,IL-1β,IL-10,D-lactic acid and endotoxin in the model group were significantly increased(P<0.01)and the relative expression of Occludin protein in the ileum tissue was significantly declined compared to the fake model group.Compared with the model group,the pathological changes in the western medicine group and the Chinese medicine group were significantly reduced,and the levels of serum amylase,TNF-α,IL-1β,D-lactic acid and endotoxin were significantly decreased(P<0.01).The level of serum IL-10 and the relative expression level of ileal Occludin were significantly rose compared to the model group(P<0.01).Compared with the western medicine group,the serum amylase,D-lactic acid and endotoxin levels in the Chinese medicine group decreased more significantly(P<0.05).Conclusion:Qingjie Huagong decoction has a certain protective effect on the intestinal mucosal barrier of AP rats,and the formula can reduce the level of serum pro-inflammatory cytokines,increase the level of anti-inflammatory cytokines,and has a significant regulatory effect on serum inflammatory factors in AP rats.
