目的探讨包膜外瘤体切除治疗肝血管瘤的手术指征和切除技巧。方法总结我院2003年7月至2009年10月采用包膜外瘤体切除治疗的26例肝血管瘤资料,术中均行血管瘤包膜外切除,切除瘤体37个,术中出血200~1200 ml,平均460 ml。同时行胆囊切除4例。结果术后发生右侧胸腔积液2例,右膈下包裹性积液2例,无手术死亡发生。术后随访6个月~5年,无血管瘤复发。结论严格掌握肝血管瘤的手术指征,包膜外瘤体切除是治疗肝血管瘤最有效、首选的治疗方法。     

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.     

胃多灶恶性淋巴瘤7例诊治体会

胃原发性恶性淋巴瘤(PGML)是指起源于原发性胃黏膜固有层淋巴组织的恶性肿瘤，约占所有胃肿瘤的1％～5％，多为单个病灶。胃多灶恶性淋巴瘤(MFGML)是指胃黏膜固有层淋巴组织多个部位发生恶变，临床上更为少见，国内尚未见类似报道。1980～2001年，我院共诊治MFGML7例，现将诊治体会报告如下。
