【Abstract】Objective To summarize the effects of vasoactive mediators on local microvasculature in acute pancreatitis（AP）. Methods Literatures concerning metabolism, receptors, action mechanisms of vasoactive mediators and their effects in AP were reviewed. Results Bradykinin, endothelin, platelet activating factor and nitric oxide were important mediators in the development of microcirculatory disturbance in AP, however the results of experiments were inconsistent. Conclusion The roles which vasoactive mediators play in microcirculatory disturbance of AP are affected by many factors, and await further study.
目的:探讨合理的营养支持方式对重症急性胰腺炎(SAP)患者营养状况及预后的影响。方法:将60例SAP患者随机分为全胃肠外营养支持(对照组)和肠内与肠外相结合营养支持(实验组)两组,对比营养支持前后两组患者的血红蛋白、总蛋白、血清白蛋白、氮平衡、血脂等生化指标,每天观察相关并发症情况。结果:实验组血清白蛋白、总蛋白、血红蛋白、氮平衡方面明显优于对照组(Plt;0.05),且并发症少。结论:肠内与肠外结合的营养支持方式可以改善SAP患者的营养状况,对SAP患者治疗有积极的作用。
【Abstract】Objective To investigate the protective effect of improving the pancreatic ischemia and calcium channel blockers on preventing the progression of acute pancreatitis. Methods Twenty-four patients with mild acute pancreatitis were randomly divided into two groups： control group and treated group. Within the first 72 hours from the onset of AP, routine conservative managements were performed in control group, improving the pancreatic ischemia and preventing Ca2+ overload were performed in treated group for two weeks. The hemorrheological parameters were measured at 1,4,7,14 days after adimission, simultanously, serum TNFα, IL-1β, C-reactive protein and plasma TXB2, 6-keto-PGF1α levels were determined with ELISA methods. Results The hemorrheological changes were improved in treated group, serum TNFα, IL-1β, C-reactive protein and plasma TXB2, 6-keto-PGF1α levels were significantly decreased each time point in treated group as compared with control group. Conclusion Improving the pancreatic ischemia and calcium channel blockers have protective effect through reducing the generation of cytokines and inflammatory mediators on preventing the progression of acute pancreatitis.
Objective To investigate the relationship between early fluid management and the conversion rate to surgery in patients with sever acute pancreatitis( SAP) .Methods The patients with SAP admitted in ICU in West China Hospital from July 2005 to June 2010 were retrospectively analyzed. They were divided into four groups according to the quartile of the accumulated fluid balance in the first three days after admission in ICU( lt; 25% , 25% ～50% , 50% ～75% , and gt; 75% , respectively) . The major demographic data, clinical characteristics, mortality, and conversion rate to surgery were evaluated respectively. Results 208 patients were enrolled. For each quartile, the conversion rate to surgery decreased at first, and then increased along with the increase of the accumulated fluid balance. Significant difference existed between the second quartile with the lowest conversion rate to surgery and other three quartiles ( P lt; 0. 05) . Differences were also found in mortality and the score of acute physiology and chronic health evaluation Ⅱ( APACHEⅡ) on 24th and 48th hour between the first three quartiles and the last quartile with the highest mortality and APACHⅡ score( P lt;0. 05) . However, sex ratio, age, Ranson criteria, and the score of sequential organ failure assessment( SOFA) did not have significant differences among each quartile( P gt; 0. 05) . Conclusion Fluid management in early stage can influence conversion rate to surgery and mortality in patients with SAP.
摘要:目的:探讨重症急性胰腺炎(SAP)继发感染的临床特点。方法:将我院20039~20053收治的SAP140例,按是否感染,分成感染组和对照组,对比分析其临床资料。结果:感染组病死率高于对照组(P=0023);感染组入院初期,Ranson评分、CT评分、APACHE Ⅱ评分、血糖、ARDS和肠麻痹发生率、感染前手术率及呼吸机辅助呼吸率高于对照组(Plt;005);以G感染胰腺、胰周围及肺部为主;肺部感染时间为107±25d,胰腺或胰周为176±29d。结论:急性期全身反应轻重及胰腺坏死程度是SAP继发感染的基础;临床有创治疗措施是促进因素。
Objective To investigate the mechanism of radix salviae miltiorrhizae (RSM) injection in treatment of pancreatitis through observing the changes of activity of nuclear factor-kappa B (NF-κB) in pancreas of rats with severe acute pancreatitis (SAP) and the influence of RSM injection upon NF-κB in pancreas tissue. Methods Seventy-five rats were randomly divided into 3 groups: normal control group, SAP group and RSM treatment group, which were injected with normal saline, normal saline or RSM in the peritoneal cavity, respectively. The model of SAP rats was made by injecting L-arginine into peritoneal cavity and by subcutaneous injection at the same time. The concentrations of amylase in plasma and in ascites were measured respectively, and the expression of NF-κB in pancreas tissues was determined by immunohistochemistry. Results The levels of amylase in plasm and ascites in SAP group and RSM treatment group increased significantly with the increased expression of NF-κB in pancreas tissue, but it was also found that both the level of amylase and the expression of NF-κB in RSM treatment group were significantly lower compared with those in SAP group, and the survival time of RSM treatment group was longer than SAP group with less pathological injury in the pancreas tissues. Conclusion RSM may be effective for the treatment of pancreatitis by degrading the expression of NF-κB.
Objective To investigate the efficiency of combining traditional Chinese medicine with western medicine in the treatment of severe acute pancreatitis (SAP). Methods The clinical results of sixty three cases of SAP of non-operative treatment with injection of Salia miltorrhizae composita, and oral or gastric tube feeding of decoction Qing-Yi-Tang were retrospectively studied. Results Thirty four cases were categorised as SAP Ⅰ grade, and 29 cases as SAP Ⅱ grade. A variety of complications occurred in 19 cases (30.16%), 3 patients died (4.76%), and 4 patients developing abscess of pancreas (6.35%) which had to be operated on.Conclusion The individualization principle on the basis of cause and clinical stage of the disease should be stressed in treating SAP. The patients who had complication needing to be operated on should be timely performed. There is a good efficiency in the treatment of SAP with the traditional Chinese medicine combining with western medicine.
