摘 要:目的:探讨金黄益胆颗粒(jinhuangyidan granules)对大鼠重症急性胰腺炎肝损伤的保护作用和可能机制.方法:54只♂SD大鼠随机分为假手术组(sham operation group,SO)、重症急性胰腺炎组(severe acute pancreatitis,SAP)和金黄益胆颗粒治疗组(jinhuangyidan granules treatment,JHT),每组分为2、6、12h三个时间点组,每个时间点组6只.5%的牛黄胆酸钠逆行胰胆管注射制备SAP模型.各组于造模后2、6、12h处死大鼠,检测血清淀粉酶(serumamylase,AMY)、谷丙转氨酶(ALT)、谷草转氨酶(AST),计算肝脏系数,HE染色观察胰腺、肝脏组织病理,酶联免疫吸附试验(ELISA)方法检测TNF-α、IL-6、ET-1水平.免疫组化检测肝脏组织中核转录因子-κB的活性.结果:各时间带点SAP组与SO组比较,AMY、ALT、AST、TNF-α、IL-6、ET-1均升高,肝脏系数在6h、12h差异有统计学意义(P<0.05);在6h、12hJHT组与SAP组比较,AMY、肝脏系数、ALT、AST、TNF-α、IL-6、ET-1指标均明显降低(P<0.05).6h时间点SO组、SAP组和JHT组NF-κB表达分别为(5.32±0.24vs49.89±3.53vs19.18±1.51),三组之间差异有统计学意义(P<0.05);12h时间点各组之间NF-κB表达分别为(6.38±0.24vs54.73±1.68vs31.15±2.25),三组之间差异有统计学意义(P<0.05).胰腺和肝脏的病理镜下观察水肿和炎性介质表达JHT组较SAP组明显改善.结论:金黄益胆颗粒可以一定程度的改善大鼠重症胰腺炎肝脏的损伤,改善微循环,其对大鼠重症急性胰腺炎肝损伤的保护作用机制可能与抑制NF-κB的活性进而下调TNF-α、IL-6的表达有关.AIM: To investigate the protective effect of Jinhuangyidan Granules on liver injury in rats with severe acute pancreatitis (SAP) and to explore the possible mechanisms involved.METHODS: Fifty-four male Sprague-Dawley (SD) rats were randomly divided into three groups: sham operation group, SAP group and Jinhuangyidan Granules group. Each group wasfurther divided into three subgroups for testing at different time points after treatment (2, 6 and 12 h). SAP was induced by retrograde injection of 5% sodium taurocholate into the biliary pan- creatic duct. Serum amylase (AMY), ALT, AST and the liver coefficient were measured. The levels of TNF-α, IL-6 and ET-1 were examined by ELISA, and the expression of NF-κB in the liver was evaluated by immunohistochemistry.RESULTS: Compared to the sham operation group, the levels of AMY, ALT, AST, TNF-α, IL-6, ET-1 and NF-KB increased significantly in the SAP group. The liver coefficient also differed significantly between the sham operation group and SAP group at 6 and 12 h (both P 〈 0.05). Compared to the SAP group at 6 and 12 h, the levels of AMY, ALT, AST, TNF-α, IL-6, ET-1 and NF-KB decreased significantly in the Jinhuangy- idan Granules group (all P 〈 0.05). At 6 h, the ex- pression of liver NF-κB was significantly higher in the SAP group than in the sham operation group at 6 and 12 h (6 h: 49.89 ± 3.53 vs 5.32 ± 0.24; 12 h: 54.73 ± 1.68 vs 6.38 ± 0.24, both P 〈 0.05), but was significantly lower in the Jinhuangyidan Granules group than in the SAP group (6 h: 19.18 ± 1.51 vs 49.89 ± 3.53; 31.15 ± 2.25 vs 54.73 _± 1.68, both P 〈 0.05). Compared to the SAP group, the levels of edema and inflammatory mediators ameliorated significantly in the Jinhuangyidan Granules group.CONCLUSION: Jinhuangyidan Granules amelio- rates liver injury and improve microcirculation in SAP rats possibly by inhibiting NF-κB activity and down-regulating inflammatory mediators.
