    • 摘要: 胰腺脂肪增多症,是一种罕见疾病,是指胰腺脏器内脂肪沉积增多,包括实质细胞内脂肪沉积及实质组织被脂肪组织替代,又称胰腺脂肪替代、多脂肪性胰腺萎缩、胰腺脂肪浸润等。自1993年首次提出胰腺脂肪增多症概念以来,相关报道有所增多,发现与其相关的疾病越来越多,包括肥胖、糖尿病、非酒精性脂肪性肝病等多种代谢性疾病,但对其发病机制仍不清楚,诊断仍未形成统一的共识。目前主要依据影像学检查辅助诊断。目前国内外对胰腺脂肪增多症研究较少,临床医师对其认识不足。本文对临床工作中发现的胰腺脂肪增多症个案进行记录报告。

    • 摘要: 目的 观察柴胡皂苷(SS)对慢性胆源性胰腺炎(CGP)大鼠胰腺外分泌功能的影响,并探讨其机制.方法 选取40只Wistar大鼠建立CGP模型,将建模成功大鼠随机分为模型组、高剂量组和低剂量组,剩余10只健康Wistar大鼠作为对照组(仅游离胆总管末端),高剂量组和低剂量组分别灌胃160 mg/kg、80 mg/kg SS溶液,对照组和模型组灌胃生理盐水溶液,每天1次,连续5 d.对比各组灌胃后第1、3、5天血清淀粉酶、胆红素水平,对比灌胃前和灌胃第1、3、5天粪弹性蛋白酶-1(FE-1)水平;末次灌胃6 h后进行胰泌素(CCK)试验并进行组织形态学观察,对比3组大鼠胰液分泌量、胰液蛋白及HCO 3-水平;并对比大鼠胰腺组织中即刻早期基因(c-fos、c-jun)mRNA及蛋白相对表达量.结果 经血清生化检验及HE染色检验,确认30只大鼠建模成功,灌胃后模型组胰腺纤维组织增生加重,低剂量组纤维组织减少;高剂量组纤维组织明显较少.灌胃后大鼠血清淀粉酶、胆红素组间比较,对照组最低、高剂量组其次、低剂量组稍高、模型组最高,且每两组间比较差异均显著(P0.05);注射后CCK后大鼠胰液分泌量、胰液蛋白及HCO3-水平均显著高于基础值(P<0.05),注射前、后上述指标比较,对照组最高、高剂量组其次、低剂量稍低、模型组最低,每两组间比较差异均显著(P<0.05);胰腺组织中c-fos、c-jun mRNA及蛋白相对表达量组间比较,对照组最低、高剂量组其次、低剂量组稍高、模型组最高,且每两组间比较差异均显著(P<0.05).结论 SS可显著改善CGP大鼠的胰腺外分泌功能,可能与c-fos、c-jun mRNA及蛋白表达抑制有关.

    • 摘要: Objective To investigate the effect of ulinastatin on pancreatic exocrine function in rats with sepsis and related mechanisms. Methods Thirty male SPF rats were randomly divided into control group,LPS group and UTI group with 10 animals in each group. The sepsis model was induced by intraperitoneal injection of LPS(15 mg/kg). Intraperitoneal injection of ulinastatin(50 000 U/kg)was given to rats in UTI group when sepsis model was established, while same volume of normal saline was given to rats in LPS group and control group. Blood samples were collected 12 h after sepsis model was made,and the level of amylase and lipase were determined by automatic biochemical analyzer,TNF-α was determined by enzyme-linked immunosorbent assay(ELISA).The morphological changes of pancreas tissue were observed by H-E staining. The apoptosis of acinar cells was determined by terminal deoxynucleotidyl transferase-mediated nick end labeling(TUNEL)assay. The expression of apoptosis factors(CytC, Caspase3,Bcl-2 and Bax)were determined by Western blotting.Results Serum amylase,lipase and TNF-α levels in LPS group and UTI group were significantly higher than those in control group(P<0.01),while the levels in UTI group was significantly lower than those in LPS group(P<0.01). The H-E staining of pancreatic tissue showed that the modified Schmidt scores of control group,LPS group and UTI group were 0,5.13 and 3.70 respectively(P<0.01). The apoptosis index in LPS group was significantly higher than that in control group(P<0.01),the index in UTI group was significantly lower than that in LPS group(P<0.01).The expressions of CytC, Caspase3 and BAX in LPS group were significantly higher than that in control group,the expressions in UTI group were significantly lower than that in LPS group;while the expression of Bcl-2 in LPS group was significantly lower than that in control group,the expression in UTI group was significantly higher than that in LPS group. Conclusion Pancreatic exocrine function is damaged in septic rats induced by LPS. Ulinastatin can protect the pancreatic exocrine function in rats with sepsis,which is associated with the inhibition of apoptosis.%目的 研究脓毒症时大鼠胰腺外分泌功能的损伤机制,并探讨乌司他丁对脓毒症所致胰腺外分泌功能损伤的保护效应.方法 SPF级雄性大鼠30只,按随机数字表法分为对照组、LPS组和UTI组,每组各10只.LPS组腹腔内注射LPS 15 mg/kg建立脓毒症模型,UTI组在腹腔内注射LPS后立即按照50000 U/kg注射UTI,LPS组、对照组均注射等量的生理盐水.12 h后留取大鼠血标本,用自动生化仪检测血清淀粉酶、脂肪酶,用酶联免疫吸附试验(ELISA)检测TNF-α;取胰腺组织,H-E染色观察胰腺形态学变化,TUNEL法计数凋亡细胞,Western印迹法检测凋亡因子CytC、Caspase3、Bcl-2、Bax基因表达水平.结果 LPS组、UTI组血清淀粉酶、脂肪酶、TNF-α均显著高于对照组(P<0.01),UTI组显著低于LPS组(P<0.01).对照组、LPS组、UTI组胰腺组织H-E染色改良Schmidt评分分别为0、5.13和3.70分,UTI组显著低于LPS组(P<0.01).凋亡细胞指数LPS组显著高于对照组(P<0.01),UTI组显著低于LPS组(P<0.01).Bax、CytC、Caspase3表达,LPS组显著高于对照组,UTI组显著低于LPS组.Bcl-2表达,LPS组显著低于对照组,UTI组显著高于LPS组.结论 LPS诱导的脓毒症大鼠存在胰腺外分泌功能损伤;乌司他丁可以保护脓毒症大鼠胰腺外分泌功能,抑制脓毒症时的细胞凋亡可能为其保护机制之一.

    • 摘要: 胰源性糖尿病是一种继发性糖尿病,美国糖尿病协会(ADA)和世界卫生组织归类为3型糖尿病.该病与胰腺的损害相关,可能是由于炎症、肿瘤或外科手术引起.胰腺的内分泌功能是由散布在胰岛中的胰腺B细胞完成的,当胰腺疾病损伤胰腺外分泌时,会破坏胰岛中的B细胞.

    • 摘要: ObjectiveTo investigate the effects of autophagy on exocrine function of pancreas in rats with acute sepsis, and to determine whether the mitochondrial coenzyme Q (Mito Q) can prevent exocrine dysfunction of pancreas mediated by autophagy.Methods ExperimentⅠ: 30 Sprague-Dawley (SD) rats were randomly divided into three groups, with 10 rats in each group. All the rats were given lipopolysaccharide (LPS, 10 mg/kg) intraperitoneally, and Wortmannin (2 mg/kg), the specific inhibitor of autophagy (LPS+ Wortmannin group), Mito Q (6.5μmol/kg, LPS+Mito Q group), or the same volume of normal saline (LPS group) was respectively injected via the tail vein 1 hour later. Survival rate was assessed within 12 hours after LPS injection. ExperimentⅡ: another 100 male SD rats were randomly divided into ten groups with 10 rats in each group: namely control 4, 6 and 12 hours groups, LPS 4, 6 and 12 hours groups, and LPS+ Wortmannin 4 hours group, Wortmannin 4 hours group, LPS+ Mito Q 6 hours group, and Mito Q 6 hours group. The protocols of model reproduction and drug administration were the same as in the experimentⅠ. Blood samples were collected at each time point, and the amylase content was determined with the velocity method. The levels of reactive oxygen species (ROS) in the pancreases were measured with enzyme-linked immunosorbent assay (ELISA). The expression of the autophagy-related protein LC3 was determined with Western Blot. The pathological changes in the pancreas were observed with microscopy.Results① The survival time in the LPS+ Wortmannin group was significantly shorter than that in the LPS group (hours: 7.50±0.64 vs. 11.90±0.13,χ2= 19.847,P= 0.001). There was no significant difference in the survival time between LPS+ Mito Q and LPS groups (hours: 11.60±0.24 vs. 11.90±0.13,χ2= 1.055,P= 0.137).② The serum amylase in the LPS 6 hours, LPS+ Wortmannin 4 hours, and LPS+ Mito Q 6 hours groups were significantly higher than those in the control group at the same time points (U/L:2 881.00±550.12 vs. 2 099.20±249.57, 3 672.00±779.24 vs. 2 081.36±245.18, 2 975.20±687.03 vs. 2 099.20± 249.57, allP 0.05). Light microscopy showed that obvious pathological changes were found in the pancreas in the LPS 6 hours and 12 hours groups, LPS+Wortmannin 4 hours group, and LPS+ Mito Q 6 hours group. Electron microscopy showed that the number of autophagic vacuoles increased 6 hours after LPS administration. There was no difference at any time point in the number of autophagic vacuoles between LPS+ Mito Q 6 hours group and LPS 6 hours group, and the autophagic vacuoles were not found after Wortmannin intervention. It was demonstrated by Western Blot that the levels of LC3 protein in the LPS 6 hours and 12 hours groups, and LPS+ Mito Q 6 hours group were significantly higher than those of the control group at the same time points (A value: 0.34±0.02 vs. 0.17±0.02, 0.37±0.03 vs. 0.18±0.04, 0.36±0.02 vs. 0.17±0.02, allP 0.05).Conclusions Autophagy prevents exocrine dysfunction of pancreas in septic rats, and the autophagic capacity or autophagosome-formation rate may determine the development of exocrine pancreatic dysfunction. The mitochondria-targeted antioxidant Mito Q does not prevent exocrine dysfunction of pancreas.%目的:探讨自噬对急性脓毒症大鼠胰腺外分泌功能的影响,以及线粒体辅酶Q(Mito Q)是否通过自噬对急性脓毒症大鼠胰腺外分泌功能障碍起保护作用。方法实验1:将30只雄性SD大鼠按随机数字表法分为3组,每组10只。所有大鼠腹腔注射脂多糖(LPS)10 mg/kg,1 h后分别经尾静脉注射自噬特异性抑制剂渥曼青霉素(Wortmannin)2 mg/kg(LPS+ Wortmannin组)、 Mito Q 6.5μmol/kg(LPS+ Mito Q组)或等量生理盐水(LPS组)。观察LPS后12 h内动物存活情况。实验2:将100只雄性SD大鼠按随机数字表法分为10组:对照4 h、6 h、12 h组,LPS 4 h、6 h、12 h组,LPS+ Wortmannin 4 h组,Wortmannin 4 h组,LPS+ Mito Q 6 h组, Mito Q 6 h组,每组10只,制模及给药方法同实验1。在相应时间点留取大鼠血标本,用速率法测定血清淀粉酶含量;取胰腺组织,用酶联免疫吸附试验(ELISA)检测活性氧(ROS)含量,蛋白质免疫印迹试验(Western Blot)检测自噬相关基因LC3蛋白表达,镜下观察胰腺组织病理学改变。结果① LPS+ Wortmannin组大鼠存活时间明显短于LPS组(h:7.50±0.64比11.90±0.13,χ2=19.847,P=0.001);LPS+ Mito Q组大鼠存活时间与LPS组无差异(h:11.60±0.24比11.90±0.13,χ2=1.055,P=0.137)。② LPS 6 h组、LPS+ Wortmannin 4 h组、LPS+ Mito Q 6 h组血淀粉酶含量明显高于同时间点对照组(U/L:2881.00±550.12比2099.20±249.57,3672.00±779.24比2081.36±245.18,2975.20±687.03比2099.20±249.57,均P<0.05),LPS 12 h组血淀粉酶含量明显低于同时间点对照组(U/L:794.00±218.71比2086.80±261.75,P<0.01);LPS 6 h和12 h组、LPS+Wortmannin 4 h组、 LPS+ Mito Q 6 h组胰腺组织ROS含量均明显高于同时间点对照组(kU/L:3.18±1.06比1.78±0.37,3.63±1.08比1.85±0.41,3.14±0.98比1.65±0.34,3.17±1.03比1.78±0.37,均P<0.05)。LPS+Wortmannin 4 h组血淀粉酶和胰腺组织ROS含量均明显高于同时间点LPS组(U/L:3672.00±779.24比2432.20±442.85, kU/L:3.14±0.98比1.87±0.42,均P<0.05),而LPS+ Mito Q 6 h组血淀粉酶和胰腺组织ROS含量与同时间点LPS组无差异(U/L:2975.20±687.03比2881.00±550.12,kU/L:3.17±1.03比3.18±1.06,均P>0.05)。光镜下观察,LPS 6 h和12 h组、 LPS+ Wortmannin 4 h组、LPS+ Mito Q 6 h组均可见明显胰腺病理改变;电镜下观察,LPS 6 h后自噬体增多,Mito Q干预后自噬体数量与相应时间点LPS组无差异,而给予Wortmannin后未见自噬体。Western Blot检测显示,LPS 6 h和12 h组、 LPS+ Mito Q 6 h组LC3蛋白表达均明显高于同时间点对照组(A值:0.34±0.02比0.17±0.02,0.37±0.03比0.18±0.04,0.36±0.02比0.17±0.02,均P<0.05),但LPS 12 h组和LPS+ Mito Q 6 h组LC3蛋白表达与LPS 6 h组比较均无差异(均P>0.05)。结论自噬对脓毒症大鼠胰腺外分泌功能障碍起保护作用,且自噬能力或自噬体形成速率可能是胰腺是否出现外分泌功能障碍的机制之一;而线粒体靶向抗氧化剂Mito Q对脓毒症大鼠胰腺外分泌功能障碍无保护作用。
