摘要: 目的

研究柴芩双解汤对急性胰腺炎所致大鼠肺损伤的保护作用及对Rho/ROCK通路的调节作用。

方法

72只大鼠随机分为假手术组,胰腺炎肺损伤组,柴芩双解汤低、中、高剂量组及法舒地尔组,每组12只。柴芩双解汤低、中、高剂量组分别灌胃给予2、4、8 mL/kg的柴芩双解汤,每日2次;法舒地尔组腹腔注射法舒地尔10 mg/kg,每日1次,连续5 d。检测大鼠动脉血氧分压(PaO2)、二氧化碳分压(PaCO2)水平及肺组织髓过氧化物酶(MPO)、环氧化酶2(COX?2)、诱导型一氧化氮合酶(iNOS)水平、肺组织RhoA、ROCK2 mRNA及蛋白水平,苏木精?伊红(HE)染色法对大鼠肺组织进行病理学检查并评分。

结果

与胰腺炎肺损伤组大鼠比较,柴芩双解汤不同剂量组大鼠血PaO2水平显著升高(P< 0.05)、血PaCO2水平及肺组织MPO、COX-2、iNOS水平、RhoA、ROCK2 mRNA及蛋白水平降低,肺组织病理学评分降低,差异均有统计学意义(P< 0.05)。

结论

柴芩双解汤能够改善急性胰腺炎所致肺损伤大鼠肺功能并抑制肺组织病理性改变,降低炎症水平及氧化损伤,其机制可能与调节Rho/ROCK通路有关。

Abstract: Objective

To study the effect of Chaiqinshuangjie decoction on lung tissue and Rho/ROCK pathway in rats with lung injury induced by acute pancreatitis.

Methods

Seventy-two rats were randomly divided into sham operation group, lung injury induced by pancreatitis group, Chaiqinshuangjie decoction low, middle and high dose groups and fasudil group, with 12 rats in each group. Chaiqinshuangjie decoction low, middle and high dose groups were given 2, 4 and 8 mL/kg Chaiqinshuangjie decoction by gavage, twice a day, and fasudil group was intraperitoneally injected with fasudil (10 mg/kg), once a day, for 5 days. The levels of arterial partial pressure of oxygen (PaO2) and partial pressure of carbon dioxide (PaCO2), the levels of myeloperoxidase (MPO), cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase ((iNOS) in lung tissue, and the levels of RhoA, ROCK2 mRNA and protein in lung tissue were measured. Pulmonary histopathology was examined and scored by hematoxylin-eosin (HE) staining.

Results

Compared with the rats in the lung injury induced by pancreatitis group, the blood PaO2level increased significantly (P< 0.05), the blood PaCO2level and the lung tissue MPO, COX-2, iNOS, RhoA, ROCK2 mRNA and protein levels decreased significantly in the Chaiqinshuangjie decoction group (P< 0.05), and the lung histopathological score decreased significantly (P< 0.05).

Conclusion

Chaiqinshuangjie decoction can improve arterial blood gas index and pathological changes of lung tissue in rats with lung injury induced by acute pancreatitis, reduce the level of inflammation and oxidative injury of lung tissue, and its mechanism may be related to the regulation of Rho/ROCK pathway.
