水通道蛋白1在急性坏死性胰腺炎大鼠胰腺组织的表达及其意义

Objective To study the expression of aquaporin 1 ( AQP1 ) in pancreas and its pathogenic role in rats with experimental acute necrotizing pancreatitis (ANP). Methods Forty-eight male Sprague-Dawley rats were randomly divided into two groups : control group ( n = 24 ) and ANP group ( n = 24). Six rats in each group were sacrificed at 3,6,12 and 18 h after induction of experimental models. Quantity of ascites and levels of serum amylases were measured at each time point. Serum AQPI was determined by ELISA. Pathological changes of pancreatic tissues were examined. Capillary permeability in pancreatic tissues was tested by Evans Blue (EB) extravasation method. AQPI expression in pancreatic tissues was detected by immunohistochemieal staining, Western blot and fluorescence quantitative polymerase chain reaction (FQ-PCR). Results (1) Serum amylase level at 3,6,12, and 18 h in control group was (1308±759) ,(1077±508), (1325±761),(1328±762) U/L,and that in ANP group was (9102± 2199), (8799±1634), (9398±1473), (9484±862) U/L respectively. The concentration of EB in pancreatic tissues at each time point in control group was (205.61±32.99), (141.46±27.18 ), (96.94± 26.79), (61.43±24.82) mg/L, and that in ANP group was ( 273.59±23.47 ), ( 253.51±31.68 ), (221.15±73.68 ), (185.28±42.35) ,respectively. There was significandy difference between two groups. Serum AQP1 level in control group at each point was ( 74.08±11.80), (78.49±9.06 ), (75.77± 7.37 ), ( 72.75±13.87 ) mg/L, and that in AN P group was (73.29±9.61 ), ( 62.85±7.28 ), (62.07± 4.39 ), (46.33±11.91 ) mg/L, respectively ( P < 0.01 ). ( 2 ) Protein expression of AQPI in pancreatic tissues detected by immunohistochemical staining in control group at each time point was 114.13±7.92, 122.39±7.99,145.98±6.48,113.98±6.48, and that in ANP group was 80.07±14.89,110.54± 4.45,103.77±10.48,99.18±6.95;Protein expression of AQP1 in pancreatic tissues detected by Western blot in control group at each time point was 1.19±0.33,1.02±0.25,0.90±0.33,1.06±0.20,and that in ANP group was 0.83±0.11,0.96±0.21,0. 58±0.28,0.72±0.14, respectively ( P < 0.05 ). ( 3 ) The mRNA level of AQP1 gene expressed in pancreas in control group at each time point was 0.91±0.22,1.01±0.83,0.48±0.23,0.61±0.51,and that in ANP group was 2.13±0.63,2.02±1.40, 2.07±0.86,2.49±2.47,respectively (P<0.01).Condusion The expression of AQP1 wasdown-reg-ulated in pancreas in rats with ANP,which might could play an important role in the pathogenesis of capil-lary leak syndrome.
