Objective To evaluate the effectiveness of enteral immunonutrition for patients with acute pancreatitis. Methods The randomized controlled trials (RCTs) about enteral immunonutrition for patients with acute pancreatitis were searched in following databases: PubMed (1966 to August 2012), MEDLINE (Ovid, 1946 to August 2012), CENTRAL (Issue 3, 2012), CBM (1978 to August 2012), CNKI (1979 August 2012), VIP (1989 to August 2012), and WanFang Data (1977 to August 2012). The relevant materials and each reference of literature were also searched manually. Two reviewers independently screened the literature according to the predefined inclusion and exclusion criteria, extracted the data and assessed the quality, and then the meta-analysis was conducted by using RevMan 5.0 software. Results A total of 6 RCTs involving 197 patients were included. The results of meta-analysis showed that there were no significant differences between the enteral immunonutrition group and the routine enteral nutrition group in following aspects: infectious complications and mortality rate, length of stay, level of C-reactive protein and numeration of leucocyte after treatment, and APACHE II score. Conclusion At present, no evidence shows enteral immunutrition is superior to routine enteral nutrition in acute pancreatitis. For the quantity and quality limitation of the included studies, more high-quality and large-sample RCTs are required to investigate the proper ingredients and dosage of enteral immunonutrition suitable for patients with acute pancreatitis.
Objective To systematically review the effectiveness and safety of alanyl-glutamine dipeptide for severe acute pancreatitis (SAP). Methods Such databases as MEDLINE, EMbase, CENTRAL, VIP, WanFang Data, CBM and CNKI were electronically searched from inception to October, 2012 for randomized controlled trials on alanyl-glutamine dipeptide for SAP. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed methodological quality. Then, meta-analysis was performed using RevMan 5.2. Results Five trials were included involving a total of 227 patients. The results of meta-analysis showed that: compared with the control group, the alanyl-glutamine dipeptide group had the lower incidence of SAP complications (RR=0.41, 95%CI 0.20 to 0.82), the lower incidence of infected pancreatic necrosis (RR=0.12, 95%CI 0.02 to 0.89), less time for alleviating bellyache (MD= –0.90, 95%CI –1.72 to –0.08). There was a tendency in decreasing SAP mortality (RR=0.15, 95%CI 0.02 to 1.19) and lessening the recovery time of blood amylase (SMD=0.37, 95%CI –0.04 to 0.79). Conclusion Current evidence shows that, alanyl-glutamine dipeptide can lower the incidence of complications and the incidence of infected pancreatic necrosis, and shorten the time for alleviating bellyache in SAP patients. Due to the limited quality of the included studies, the above conclusion needs to be verified by more high quality studies.

Objective To establish a stable and reliable lung injury model caused by severe acute pancreatitis（SAP）in rats， which is helpful to study the acute lung injury （ALI）and acute respiratory distress syndrome （ARDS） induced by SAP.Methods Sixty Sprague-Dawley rats were randomized into ligature group （n=20）， traditional group （n=20），and sham operation group （n=20）. SAP model was established through retrograde injection of 5% taurocholic acid. After injection， the pancreatic duct of rats was ligated in ligature group， but not in traditional group. The lung damage and edema at 24 h after operaton and natural course of rats were observed.Results The ALI model of rats induced by SAP was established successfully in ligature group. The rats died of acute respiratory failure within 48 h in ligature group， the mortality was significantly higher than that in traditional group （100% vs.20%），P＜0.05. Pleural effusion occurred in four rats in ligature group， while no pleural effusion was found in rats in other two groups. The volume of ascites of rats in ligature group was （21.15±5.33） ml， which was more than that in traditional group 〔（7.75±2.66） ml〕，P＜0.05， while no ascites was found in rats in sham operation group. The level of serum amylase of rats in ligature group was （2 470.70±399.73） U/L，which was significantly higher than that in traditional group 〔（1 528.40±289.54） U/L〕 and sham operation group 〔（831.10±93.26） U/L〕，P＜0.001. The level of serum albumin of rats in ligature group was （6.90±1.66）g/L， which was significantly lower than that in traditional group 〔（13.10±0.99） g/L〕 and sham operation group 〔（16.20±0.92） g/L〕，P＜0.001.The lung wet-to-dry weight ratio （W/D） of rats in ligature group was 6.50±0.23， which was greater than that in traditional group （4.92±0.18） and sham operation group （4.61±0.16）， P＜0.001. The score of lung histopathologic of rats in ligature group was 29.25±1.07， which was significantly higher than that in traditional group （12.65±1.98） and sham operation group （0），P＜0.001. The score of pancreas histopathologic of rats in ligature group was 15.95±0.15，which was significantly higher than that in traditional group （13.75±0.66） and sham operation group （0.13±0.29），P＜0.001. Under transmission electron microscope， basement membrane of pulmonary capillary of rats in ligation group was destructive， the nuclei was dissolved， endothelial pinocytotic vesicles was functional active， and tight junctions between capillary endothelial cells were blurred and even ruptured. Moreover， tight junctions between alveolar epithelial cells were destructive. Pathological changes of lung ultrastructure of rats in ligation group were more severe than that in traditional group， while no pathological change of lung ultrastructure was observed in rats in sham operation group. Conclusions Injury process and pathogenesis of ALI or ARDS clinically caused by acute gallstone pancreatitis can be reproduced in this animal model， which is suitable to explore the related mechanisms of ALI caused by SAP and provides good animal model for the study of ALI caused by SAP.
ObjectiveTo study the effects of continuous regional arterial infusion (CRAI) of dexamethasone on plasma inflammatory factors of severe acute pancreatitis (SAP) rabbits. MethodsTwentyfour rabbits were randomly divided into sham operation group, SAP group, intravenous infusion of dexamethasone group and CRAI of dexamethasone group (each group 6 rabbits) by random number table. The serum tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-10, and amylase (AMY) levels in rabbits were tested at hour 0.5, 3, 6, 9, and 12 after modeling succeed. The pathological changes of pancreas and the survival were observed on day 3 after modeling succeed. ResultsCompared with the sham operation group, the serum levels of IL-6 significantly increased at 3 h and reached the peak at 6 h, decreased at 9 h (all Plt;0.05); levels of IL-10 significantly increased at 6 h, continuously elevated at 9 h and 12 h (all Plt;0.001); levels of TNF-α significantly increased at 0.5 h (Plt;0.001), reached the peak at 6 h (Plt;0.001) and decreased at 9 h (Plt;0.05); levels of AMY significantly increased at 9 h, continuously elevated at 12 h (all Plt;0.05) in the SAP group. Compared with the SAP group, the serum levels of IL-6 and IL-10 in the CRAI of dexamethasone group all significantly decreased at 6 h, 9 h, and 12 h (Plt;0.001); levels of IL6 significantly decreased only at 6 h in the intravenous infusion of dexamethasone group; levels of TNF-α in the CRAI of dexamethasone group significantly decreased at 3 h, 6 h, 9 h, and 12 h (all Plt;0.001), which in the intravenous infusion of dexamethasone group significantly decreased only at 6 h (Plt;0.05); levels of AMY in the CRAI of dexamethasone group and intravenous infusion of dexamethasone group all significantly decreased at 12 h (Plt;0.05). Compared with the intravenous infusion of dexamethasone group, the serum levels of IL-6 and IL-10 in the CRAI of dexamethasone group all significantly decreased at 6 h (Plt;0.05) and 12 h (Plt;0.001); levels of TNF-α all significantly decreased at 3 h, 6 h, 9 h, and 12 h (all Plt;0.001); levels of AMY were not significantly different (Pgt;0.05). The pathological changes of pancreas in the CRAI of dexamethasone group were obvious, the death of rabbits reduced on day 3 after modeling succeed. ConclusionCRAI dexamethasone can effectively reduce the systemic inflammatory response and pancreatic inflammation, and reduce mortality.
Objective To investigate the value of CT grading diagnosis in clinical therapy of acute pancreatitis. Methods CT scanning was carried out in patients with acute pancreatitis between 2003 and 2009, and Enhancement CT scanning was carried out in patients without contraindications of contrast medium. Two radiologists analyzed the images and made CT grading diagnose. Contrast study was made between CT grading diagnose and clinical scale as well as prognosis. Results In 518 cases, the CT grading was as the following: grade A 9 cases, grade B 66 cases, grade C 105 cases, grade D 147 cases, and grade E 191 cases. Patients with grade A and B were fully recovered after conservation and supportive treatment. In cases of grade C, only 2 patients had recurred pancreatitis after conservation treatment, and others were fully healing. Ninety-four patients who needed operation and 23 patients who died were all occurred in grade D and E. Conclusion CT grading diagnosis of acute pancreatitis can reflect the range, extent, and course of disease, and it has good dependablity with clinical grading.
