隔药灸和电针对大鼠克罗恩病肠纤维化血清学指标的影响

目的:观察隔药灸和电针对克罗恩病(Crohn's Disease,CD)肠纤维化大鼠血清透明质酸(Hyaluronic Acid,HA)、Ⅲ型前胶原(Procollagen Ⅲ,PC Ⅲ)、Ⅳ型胶原(Collagen Ⅳ,C Ⅳ)的影响,探讨针灸抗CD大鼠肠纤维化的作用与机制.方法:SD大鼠随机分为正常组、模型组、隔药灸组、电针组和药物组.采用三硝基苯磺酸制备大鼠CD模型,应用Masson染色光镜下观察结肠胶原纤维增生情况,采用放射免疫分析技术检测大鼠血清HA、PC Ⅲ、CⅣ含量.结果:与正常组比较,模型组大鼠结肠组织胶原纤维增生,血清HA、PCⅢ、CⅣ含量增加;与模型组比较,隔药灸组、电针组及西药组胶原纤维表达减少,血清中HA、PCⅢ、CⅣ含量降低,与电针组、西药组比较,隔药灸组胶原纤维表达减少,血清CⅣ含量降低.结论:隔药灸和电针均可改善CD大鼠肠纤维化病理状态,降低血清HA、PCⅢ、CⅣ含量.

Abstract：

Objective:To observe the impact of herb-partitioned moxibustion and electroacupuncture on hyaluronic acid(HA),procollagen Ⅲ(PC Ⅲ)and collagen Ⅳ(CⅣ)of intestinal fibrosis in rats with Crohn's disease(CD),and discuss the effect and the mechanism of acupuncture on treating intestinal fibrosis of rats.Methods:SD rats were randomly divided into control group,model group,herb-partitioned moxibustion group,electroacupuncture group and medicine group.The model of CD was developed by trinitrobenzene sulfonic acid.Masson stain was used to observe the collagen fibers hyperplasia in colon and radioimmunoassay was adopted to detect the content of HA,PC Ⅲ and C Ⅳ in serum.Results:Compared with the control group,the proliferation of colonic collagen fibers,as well as the HA,PC Ⅲ and CⅣ in serum increased in the model group.Compared with the model group,the expression of collagen fibers,serum HA,PC Ⅲ and C Ⅳ decreased in the herb-partitioned moxibustion group,electroacupuncture group and medicine group.The expression of collagen fibers serum HA,PC Ⅲ and C Ⅳ in the herb-partitioned moxibustion group were lower than in the electroacupuncture group and medicine group.Conclusion:Herb-partitioned moxibustion and electroacupuncture effectively improved the pathological state of intestinal fibrosis in rats with CD and reduced the content of HA,PC Ⅲ and C Ⅳ in serum.     

不同灸量隔药灸对溃疡性结肠炎大鼠结肠组织病理学的影响

目的:观察隔药灸不同灸量对溃疡性结肠炎(UC)大鼠结肠损伤的作用差异,从组织病理学角度筛选隔药灸干预UC大鼠的最佳灸量组合。方法:SD大鼠随机分为正常组、模型组、西药组、隔药灸1组、隔药灸2组、隔药灸3组、隔药灸4组,每组9只。采用抗原免疫加局部化学刺激法制备UC模型。隔药灸各组选取双侧"天枢"穴给予不同灸量组合(每日1壮、每日2壮、隔日1壮、隔日2壮)隔药灸治疗。观察大鼠一般情况,苏木素-伊红(HE)染色观察结肠组织形态变化,过碘酸雪夫(PAS)染色观察结肠黏蛋白分泌情况,高铁二胺-阿辛蓝(HID-AB)染色观察结肠黏蛋白硫酸化程度。结果:与正常组比较,模型组大鼠便稀,肛周脓血分泌,体质量增加缓慢(P0.01);巨检显示模型大鼠结肠充血明显,严重者局部存在数个浅小溃疡;HE染色镜检显示结肠浅表性溃疡连续分布,腺腔不规则,黏膜固有层、黏膜下层水肿伴大量炎性细胞浸润,组织损伤评分显著升高(P0.01);PAS染色、HID-AB染色显示结肠肠腺黏蛋白明显减少(P0.01)。与模型组比较,西药组及隔药灸各组大鼠均体质量增加(P0.01,P0.05),大便成形,结肠组织损伤改善,表现为黏膜愈合和炎性反应减轻,损伤评分明显降低(P0.01);PAS染色、HID-AB染色显示隔药灸各组大鼠结肠腺体分泌黏蛋白增加(P0.01)。两因素两水平析因分析结果显示,隔日灸对组织学评分的改善作用优于每日灸(P0.05),隔日灸2壮对黏蛋白硫酸化程度的调节效应优于1壮(P0.01)。隔药灸壮数与频次对结肠组织评分、黏蛋白分泌均有交互作用,共同影响灸效。结论:隔药灸"天枢"穴具有促进UC大鼠结肠损伤修复及黏液分泌作用,隔日2壮灸为最佳灸量组合。
