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.
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.
