ObjectiveTo summary the effect of parenteral nutrition combined with enteral nutrition on patients with severe acute pancreatitis. MethodsThe clinical data of 200 patients with severe acute pancreatitis admitted in our hospital in recent 10 years were retrospectively analyzed. Of which 88 cases were treated by traditional nutritional support therapy (traditional nutrition group), the rest of 112 cases of patients with early parenteral nutrition to later period gradually combined with enteral nutrition comprehensive nutritional support strategy (comprehensive nutrition group). ResultsThe APACHEⅡscores and serum level of C-reactive protein (CRP) of patients in comprehensive nutrition group were significantly lower than patients in traditional nutrition group (P < 0.05), while the serum albumin level was significantly higher than that of traditional nutrition group (P < 0.05). In the incidence of complications and mortality, the average length of stay and total cost of comprehensive nutrition group were significantly lower than patients with traditional nutrition group (P < 0.05), the cure rate was significantly higher than that of traditional nutrition group (P < 0.05). ConclusionThe combination of parenteral nutrition and enteral nutrition of nutrition support model not only can shorten the duration of symptoms but also alleviate the burden of patients and reduce complications and mortality.
Background Acute pancreatitis is one of the most severe acute abdominal conditions. Recently with the understanding of pathophysiology and pathogenesis of acute pancreatitis, cytokines, especially platelet-activating factor (PAF), have been shown to play an important role. Lexipafant is a potent inhibitor of PAF. It has shown exiting results in the animal experiments, so randomized controlled studies are needed to assess the impact of lexipafant for acute pancreatitis. Objectives To determine whether lexipafant can alter the course, prevent or treat organ failure and reduce mortality in acute pancreatitis. Search strategy Electronic databases were searched and reference lists from included studies were also handsearched. Published abstracts from conference proceedings and ten kinds of Chinese medical journals were handsearched for additional citations. Personal contaction with colleagues and experts in the field of pancreatitis was performed to identify potentially relevant trials. Selection criteria Randomized, controlled trials, In which participants went in hospital within 72 hours of belliache episode, comparing lexipafant to placebo or other interventions on organ failure rate or mortality of acute pancreatitis. Data collection and analysis Data related to the clinical outcomes were extracted by two reviewers independently, if there was any divarication, they would have a discussion. Main Results Three studies meet the inclusion criteria up to 2001. Compared with control group, lexipafant had the tendency of reducing the early deaths (odds ratio [OR] 0.56, 95% confidence interval [CI] 0.23 to1.38, P=0.2), accelerating the recovery of organ failure (OR 0.40, 95%CI 0.12 to 1.32, P=0.13) and reducing the occurrence of new organ failure OR 0.34, but these results had no statistical significance. A large-scale multicentre randomized controlled trial including 1 500 patients has been completed in America, but the result has not been published. Reviewers’ Conclusions Current evidence couldn’t draw the final conclusion. So the large-scale of randomized controlled trials is required.
ObjectiveTo investigate clinical efficacy of percutaneous nephroscope in treatment of patients with severe acute pancreatitis (SAP). MethodsEighty-six patients with SAP in this hospital from August 2012 to November 2015 were selected, which were divided into percutaneous nephroscope treatment group (43 cases) and laparotomy treat-ment group (43 cases) according to the difference of therapy modality. The conventional drug therapy was performed for all of them. The postoperative recovery, content of serum C reactive protein (CRP) on day 14 after operation, and post-operative complications were observed in these two groups. Results① The abdominal pain relief time, postoperative bowel sounds recovery time, normal body temperature recovery time, and postoperative hospitalization time in the percu-taneous nephroscope treatment group were significantly shorter than those in the laparotomy treatment group (P<0.05). ② The contents of serum CRP in the percutaneous nephroscope treatment group and in the laparotomy treatment group on day 14 after operation were significantly lower than those on day 1 before operation[(8.35±2.13) mg/L versus (31.44±3.45) mg/L, P<0.05; (16.42±2.44) mg/L versus (32.09±2.98) mg/L, P<0.05]. On day 14 after operation, the content of serum CRP in the percutaneous nephroscope treatment group was significantly lower than that in the laparotomy treat-ment group[(8.35±2.13) mg/L versus (16.42±2.44) mg/L, P<0.05]. ③ The incidence rate of postoperative complications in the percutaneous nephroscope treatment group was significantly lower than that in the laparotomy treatment group[14.0% (6/43) versus 32.6% (14/43), P<0.05]. ConclusionPercutaneous nephroscope in treatment of patients with SAP is effect, it has advantages of shorter hospital stay and early recovery, which could reduce incidence of postoperative complications, and it's mechanism might be related to systemic inflammatory response.

Researching the related cytokines will contribute to the diagnosis and treatment for severe acute pancreatitis with lung injury.
Objective To examine the effects of carbon dioxide (CO2) pneumoperitoneum on local pancreas pathological changes, serum levels of amylase, IL-1, IL-6, and the positive rate of dissolubility adhesion molecule (CD11a/CD18 and CD11b/CD18) expression in rats with severe acute pancreatitis (SAP). Methods Fifty healthy male SpragueDawley (SD) rats were randomly divided into 3 groups: CO2 pneumoperitoneum group (n=20): SAP was induced by injecting 5% sodium taurocholate through retrogradely common biliopancreatic ducts via duodenal papilla， and then CO2 pneumoperitoneum was established at a pressure of 12 mm Hg (1 mm Hg=0.133 kPa) for 30 min; SAP group (n=20): The rats were treated as same as CO2 pneumoperitoneum group, except CO2 pneumoperitoneum； Simple operation group (n=10): Laparotomy was performed and nothing was done to duodenum and pancreas except for moving them softly. The blood samples were collected for examining serum levels of amylase, IL-1, IL-6, and the positive rates of CD11a/CD18 and CD11b/CD18 expression, and histopathologic examination of pancreas was performed. Results Compared with simple operation group, the pancreatic pathologic histology score, serum levels of amylase, IL-1, IL-6, and the positive rates of CD11a/CD18 and CD11b/CD18 expression were significantly higher in CO2 pneumoperitoneum group and SAP group (P=0.000). The levels of IL-1 and IL-6 were significantly lower in CO2 pneumoperitoneum group as compared to SAP group (P=0.000). There was no significant difference between CO2 pneumoperitoneum group and SAP group in pancreatic pathologic histology score (P=0.294), the level of serum amylase (P=0.073), the positive rates of CD11a/CD18 (P=0.155) and CD11b/CD18 expression (P=0.201). Conclusion CO2 pneumoperitoneum has inhibitory effect on the levels of IL-1 and IL-6, rather than the positive rates of CD11a/CD18 and CD11b/CD18 expression in SD rats with SAP.
Objective To investigate the changes of expression of zonula occludens-1(ZO-1) in rats with severe acute pancreatitis (SAP), and to study the relationship between the ZO-1 protein and microvascular injury in rats with SAP. Methods Forty-eight Wistar rats were randomly divided into sham-operation (SO) group and SAP group, each group enrolled 24 rats. Pancreas of rats in SO group were flipped only after laparotomies, but rats of SAP group were injected with 5% sodium taurocholate by retrograding cholangiopancreatography micro pump to produce the SAP model. At 6, 12, and 24 hours after operation, 8 rats were sacrificed to get abdominal aortic blood for testing the levels of peripheral blood amylase, trypsin, interleukin-8(IL-8), tumor necrosis factor-α(TNF-α), and ZO-1 protein. At the same time, pancreatic tissues were got to perform HE staining and immunohistochemical staining for observation of the pathological changes and the expression of ZO-1 protein respectively. Results Compared with SO group at the same time, the levels of peripheral blood amylase, trypsin, IL-8, TNF-α, and ZO-1 protein were all higher in SAP group (P < 0.05). The level of amylase in SAP-24 hours group was higher than those of 6 hours group and 12 hours group(P < 0.05), the levels of trypsin, IL-8, and ZO-1 protein in SAP group increased over time (P < 0.05), but levels of TNF-αin 3 time points of SAP group did not differ with each other significantly(P > 0.05). Results of regression showed that in the SAP group, the level of ZO-1 protein in serum was significantly positive correlated with pathological score of pancreatic tissue(b=0.96, P < 0.05), levels of serum amylase(b=0.87, P < 0.05), trypsin(b=0.72, P < 0.05), and serum IL-8 (b=0.69, P < 0.05), but was not significantly correlated with level of TNF-α(P > 0.05). HE staining results showed that damage of pancreatic tissues became worse over time in SAP group, and the pathological score of SAP-6 hours group was lower than those of 12 hours group and 24 hours group (P < 0.05). Immunohistochemical staining results showed that, in SAP group, with the extension of time, the number of ZO-1 protein granules in pancreatic acinar cells and capillary wall reduced, and expressed in capillaries discontinuously. Conclusion During the course of SAP, the concentration of serum ZO-1 protein increase, but its expression in the pancreatic tissue degrade, which is closely associated with microvascular injury and progression of pancreatic tissues.
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.
ObjectiveTo understand the incidence and mechanism of posthepatectomy acute pancreatitis (PHAP) after liver resection, and to explore diagnosis, treatment, and preventive strategies to enhance prognosis for the patients with PHAP. MethodThe literature on studies relevant PHAP both domestically and internationally was retrieved and reviewed. ResultsThe incidence rate of PHAP was approximately 0.7% by the literature. The exact etiology was still unclear. According to the existing research results, it was speculated that the pathogenesis might be related to the portal vein congestion, reactive oxygen species, surgical trauma, and other factors. At present, there were no comprehensive guidelines for the diagnosis and treatment of PHAP after liver resection both domestically and internationally. The diagnosis was mainly based on the clinical manifestations, early signs and symptoms, biochemical examination and imaging evaluation. The treatment principle of the PHAP was similar to that of common acute pancreatitis. The symptomatic supportive treatment was performed for the patients with mild to moderate PHAP, while the surgical treatment and minimally invasive surgery were chosen for the severe PHAP. The best way prevented for PHAP was the preoperative comprehensive evaluation of patients, and quit smoking and drinking, and so on. The careful operation should be performed during the surgical process to minimize portal vein congestion and reduce reactive oxygen species in blood vessels.The blood biochemistry, hematuric amylase, pancreatic function, and relevant infection indicators should be closely monitored after surgery, and abdominal ultrasound should be repeated several times to achieve early identification and timely treatment. ConclusionsAlthough the incidence rate of PHAP is not high, it is a serious surgical complication. The prevention, early detection, and early treatment should be strengthened for PHAP, and we should focuse on earlier and more accurate prediction model in future.

Ranson score, CT score, Acute Physiology and Chronic Heath EvaluationⅡscore (APACHEⅡ score) and the incidences of complications were no statistical differencein the two groups(P ＞005)in the early stage of hospitalization. But the APACHEⅡ score (497±239)in earlytreated group was lower than those in latetreated group(863±357)after 15 days(P ＜001 The duration of acute respiratory distress syndrome(ARDS ),renal failure, shock, hepatic failure, encephalopathy and enteroplegia were shorter in earlytreated group than those in latetreated group(P＜005 . The incidence of infection, operation and mortality were lower in earlytreated group than those in latetreated group(P＜005 . The course of diseases of earlytreated group was shorter than that of latetreated group (P＜005 . Conclusion : SAP treated by (CQCQD) and AlaGln in early stage can shorten the duration of complications and the hospitalization period, and reduce the incidences of infection, operation rates and mortality rate.
Objective To investigate the mechanism of gastrointestinal motility disorder of severe acute pancreatitis （SAP） in rats. Methods SD rats were randomly divided into 2 groups：sham operation （SO） group （n=16） and SAP group （n=16）. The gastric antrum interdigestive myoelectric complex （IMC） of rat was recorded by using bipolar silver electrode recording， the concentration of serum motilin （MTL） and vasoactive intestinal peptide （VIP） were detected by enzyme-linked immunosorbent assay （ELISA） method， and determined the pancreatic pathology score. Results Compared with SO group， the concentration of serum MTL obvious decreased and the concentration of VIP obvious rised in SAP group （P＜0.01）. Compared with SO group， the time of IMC cycle， andⅠand Ⅱ phase were extended， and time of Ⅲ phase was shortened， also the amplitude and frequency of peak electric of Ⅲ phase were declined in SAP group （P＜0.01）. And the concentration of MTL in SAP group showed positive correlation with the time of Ⅲ phase of IMC （r=0.967， P＜0.01）， the concentration of VIP in SAP group showed negative correlation with the time of Ⅲ phase of IMC （r=-0.592， P＜0.05）. The pancreatic organization pathological score in SAP group was higher than that in SO group （P＜0.01）. Conclusion There is gastrointestinal motility disorder in SAP rats， furthermore， it may induce gastrointestinal motility disorder through effecting the gastrointestinal smooth muscle electrical activity.
