Objective To evaluate the activity of the pancreatic tissue phospholipase A2 (PLA2) in acute pancreatitis (AP) and the therapeutic effects of verapamil in rats. MethodsThe model of rat AP induced by a closed duodenal loop technique was established to observe the changes of PLA2 activity in AP group and treated group. The pancreatic histology was examined by light and electron microscopy. Results At 16 and 24 hours after induction of AP in rats, significant inhibition of the pancreatic tissue PLA2 activity was shown in the treated group as compared with AP group, with 32.34±3.87u, 35.26±4.52u and 44.83±5.31u, 47.77±5.86u respectively. The treated animals also showed a decrease in the severity of pancreatic hemorrhage, necrosis and damage to the cellular ultrastructures. Conclusion There exists high activity of PLA2 in rats AP. Calcium channel blocker, verapamil might take therapeutic effects on AP by inhibiting activity of PLA2.
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.
ObjectiveTo explore the correlation of serum lipocalin-2 (LCN2) with inflammation and the predictive value of LCN2 for detecting acute kidney injury (AKI) in acute pancreatitis (AP).MethodsNighty-one patients with AP, who were admitted to Bazhong Municipal Hospital of Traditional Chinese Medicine between June 2016 and June 2018, were enrolled in the present study. Clinical paramaters were analyzed between patients with AKI (n=29) and patients without AKI (n=62). The correlation of serum LCN2 with inflammation was assessed with Pearson’s correlation analysis. The area under the receiver operating characteristic curve (ROC AUC) for serum LCN2 predicting AKI in AP patients was assessed.ResultsCompared with the patients without AKI, the patients with AKI showed increased serum levels of C-reactive protein [(64.8±10.5) vs. (148.3±21.6) mg/L], procalcitonin [(3.5±2.3) vs. (4.8±3.9) μg/L], urea nitrogen [(5.5±2.1) vs. (6.6±2.8) mmol/L], creatinine [(80.3±28.1) vs. (107.3±30.8) μmol/L], interleukin-6 [(10.1±3.7) vs. (16.2±4.6) pg/mL], and LCN2 [(155.0±37.6) vs. (394.8±53.1) mg/mL], as well as decreased level of calcium [(2.6±1.3) vs. (2.0±1.0) mmol/L], the differences were all statistically significant (P<0.05). The serum level of LCN2 was correlated with C-reactive protein (r=0.694, P<0.05), interleukin-6 (r=0.762, P<0.05), and procalcitonin (r=0.555, P<0.05) in patients with AP. The ROC AUC of LCN2 for predicting AKI was 0.844 (P<0.05) , with a sensitivity of 81.3% and a specificity of 81.4% when the cut-off value was 210.2 ng/mL.ConclusionsSerum LCN2 concentration is elevated in patients with AKI. In patients with AP, serum LCN2 level is positively correlated with C-reactive protein, interleukin-6, and procalcitonin. It can be regarded as a reliable indicator for predicting AKI.
Objective To evaluate the effect of early clinical interference strategies on preventing the conversion of acute pancreatitis to the severe form and aggravation of severe acute pancreatitis (SAP). Methods The patients with acute pancreatitis admitted to this hospital were divided into two therapeutic phases by different therapeutic methods from January 2001 to December 2008. Patients in the first phase (from January 2001 to December 2004) were treated by the routine management, and the second phase (from January 2005 to December 2008) by the routine management combined with early clinical interference strategies. Then, the ratio of conversion from acute pancreatitis to SAP and prognosis of SAP between two phases were compared. Results Compared with the first phase, the rate of aggravation of acute pancreatitis was significantly decreased in the second phase (4.48% vs. 21.18%), the average healing time of SAP, the incidences of systemic and local complications and the mortality of pancreatitis were reduced (P＜0.05). When early clinical interference strategies were performed, some adverse reaction and complications occurred in 35 cases, but without severe consequence. Conclusion Early clinical interference strategies may serve as a beneficial strategy on preventing the progression of mild acute pancreatitis to the severe form or halting the aggravation of acute pancreatitis.

【Abstract】Objective To study the change of pancreatic microcirculation in the early phase of acute pancreatitis. MethodsLiteratures on acute pancreatitis and microcirculation were collected and reviewed.ResultsPancreatic microcirculation has changed in the early phase of acute pancreatitis, including contraction of interlobular arteriole, slowing of blood fluid, increasing of pancreatic vascular permeability, leukocyte adherence in postcapillary venules, and decreasing of pancreatic perfusion.Conclusion Impairment of pancreatic microcirculation in the early phase of acute pancreatitis may play a key role in the progression of this disease.
ObjectiveTo systematically review the efficacy and safety of early abdominal paracentesis drainage (APD) in patients with severe acute pancreatitis (SAP). MethodsThe PubMed, Cochrane Library, Web of Science, CNKI, WanFang Data, and VIP databases were searched to collect randomized controlled trials and cohort studies on the management of SAP via early APD from inception to December 10, 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.4 software and Stata 17.0 software. ResultsEighteen studies were included, with a total sample size of 2 685 patients. The meta-analysis showed that early APD could decrease mortality (OR=0.49, 95%CI 0.35 to 0.69, P<0.01) and the incidences of multiple organ failure (OR=0.56, 95%CI 0.45 to 0.71, P<0.01), ARDS (OR=0.54, 95%CI 0.41 to 0.71, P<0.01), and infectious complications (OR=0.72, 95%CI 0.57 to 0.92, P<0.01) and also reduce the need for further interventions and the total cost incurred during hospitalization, reduce the length of hospital stay, and reduce the number of days spent in the intensive care unit. However, there were no significant differences in the incidence of pneumonia, bacteremia, and sepsis between the two groups. ConclusionThe treatment of SAP via early APD, which has high clinical value, could decrease the incidence of multiple organ failure, improve the prognosis of patients, and reduce the associated mortality rate. Moreover, APD does not increase the risk of infection-related complications. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Objective To summarize the role of inflammatory cytokines in the pathogenesis of acute pancreatitis (AP) and gut barrier dysfunction in recent years. Methods Literatures on cytokines and experimental pancreatitis as well as clinical pancreatitis were collected and reviewed. Results Tumor necrosis factor-α and other inflammatory cytokines were elevated significantly during pancreatitis in many tissues, especially in pancreas and alimentary tract, in a fashion independent of the animal model used. Anti-cytokine therapy could decrease the concentration of the cytokines in experimental animal. Conclusion Inflammatory cytokines are believed to be primarily responsible for the pathogenesis of acute pancreatitis and its associated distant organ dysfunction. Further study of the nature of these cytokines may provide a new approach to treating this disease.
