Methods : Twentyfour SAP patients who admitted to hospital within 72h after onset were randomized into treatment group (n=12) and control group (n=12). The patients in the treatment group were treated by Yihuo Qingxia method, and the control group were administrated with placebo.The level of the serum mcp1 of the patients on the first,3rd,5th,7thday were measured, as well as the incidence and the duration of disfunction of the organs were compared.〖WTHZ〗Results :There were no statistical significance in admission Rason scores, CT scores, Acute physiology and chronic health evaltionⅡscores(APACHEⅡscores)(Pgt;005). The level of the serum Monocyte chemoattractant protein1 of the treatment group was lower than that of the placebo group generally(Plt;005).At the 3rd day after onset,the serum mcp1 level of the control group was significantly higher than that of the treament group(Plt;005).The incidence of the control group of the intestin disfunction and hepatic inadequacy was obviously higher than those of the treatment group,and the duration of the former was longer than that of the latter,but with no satistical significance. Conclusion :Yihuo Qingxia method can effectively cut down the level of the serum mcp1 of severe pancreatitis patients.
In February 2020, the American College of Gastroenterology (ACG) published the latest guideline on chronic pancreatitis, and put forward practical recommendations on the etiology, natural history, diagnosis, treatment, prognosis and follow-up of chronic pancreatitis. This paper aims to provide references for the diagnosis and treatment of chronic pancreatitis in China by interpreting the main content of the guideline and comparing it with related guidelines or consensuses domestically and abroad.
ObjectiveTo explore the protective effect of rapamycin on pancreatic damage in severe acute pancreatitis (SAP) and further to explain its protective mechanism.MethodsNinety selected SPF males SD rats were randomly divided into 3 groups: sham-operated group (SO group), SAP group, and rapamycin group (RAPA group), with 30 rats in each group. Then each group of rats were randomly divided into 3 subgroups of 24 h, 36 h, and 48 h, 10 rats in each subgroup. Rats in each group underwent laparotomy, the model was prepared by retrograde injection of solutions into biliopancreatic duct, rats of the SO group were injected with 0.9% normal saline, rats of the SAP group and RAPA group were injected with 5% sodium taurocholate solution, but rats of the RAPA group were injected with rapamycin at 30 min before the injection of 5% sodium taurocholate. All the survival rats in corresponding subgroup were killed at 24 h,36 h, and 48 h after operation respectively, then serum and pancreas tissues of rats were collected, serum inflammatory factors content of IL-1β, IL-6, and TNF-α were detected by ELISA method, expression levels of p-mTOR and p-S6K1 in pancreas were detected by Western blot, pancreas tissues were stained by Hematoxylin-Eosin Staining and pathological changes of pancreas were scored under light microscope.Results① At the timepoint of 24 h, 36 h, and 48 h, the order of the expression levels of p-mTOR and p-S6K1 in pancreatic tissues of 3 groups were all as follows: SO group<RAPA group<SAP group, there were significant difference among any 2 groups (P<0.05). ② IL-1β: at the timepoint of 48 h, the order of the content of IL-1β in 3 groups were as follows: SO group<RAPA group<SAP group, there were significant differences among any 2 groups (P<0.05); IL-6: at the timepoint of 36 h and 48 h, the order of the content of IL-6 in3 groups were as follows: SO group<RAPA group<SAP group, there were significant differences among any 2 groups (P<0.05); TNF-α: at the timepoint of 48 h, the order of the content of TNF-α in 3 groups was as follows: SO/RAPA group<SAP group (P<0.05), but there was no significant difference between the SO group and RAPA group (P>0.05). ③ Pancreatic histological score: at the timepoint of 24 h, 36 h, and 48 h, the order of the pancreatic histological score in3 groups was all as follows: SO group<RAPA group <SAP group, there were significant differences among any 2 groups (P<0.05). ④ The expression levels of p-mTOR and p-S6K1 in pancreatic tissue were positively correlated with the pathological scores of pancreatic tissue (r=0.97, P<0.01; r=0.89, P<0.01).ConclusionRapamycin can reduce the degree of pancreatic damage in SAP and has protective effect on pancreatic tissue.
Objective To evaluate the role of interleukin-10 (IL-10) in acute pancreatitis. Methods Thirty mongrel dogs were divided into three groups based on the severity: acute edematous pancreatitis (AEP) group (n＝11), acute hemorrhagic necrotizing pancreatitis (AHNP) group (n＝12), and control group (n＝7). Serum level of IL-10 was determined with enzyme-linked immuno-sorbent assay (ELISA). Results Within 24 hours, AEP group had serum level of IL-10 significantly higher than that of AHNP group. Control group had no detectable serum IL-10. No significant difference was observed between AEP group and AHNP group at 48 hours. Conclusion The finding of low values of serum IL-10 suggests that there may be more consumption in AHNP group than in AEP group and it may be beneficial to decrease the severity of experimental acute pancreatitis.
ObjectiveTo summarize the changes and interaction of the cytokine in severe acute pancreatitis associated lung injury. MethodsThe published literatures at domestic and aboard in recent years about severe acute pancreatitis associated lung injury were collected and reviewed. ResultsThe cytokines had a chain effect, and influenced each other when severe acute pancreatitis with lung injury attacked. ConclusionsRelated cytokines play important roles in severe acute pancreatitis associated lung injury. Researching the related cytokines will contribute to the diagnosis and treatment for severe acute pancreatitis with lung injury.
Fifty three patients with acute necrotizing pancreatitis were performed operation, treated surgically, including incision of the pancreatic capsule to release the pancreatic presure, removal of necrotic tissue, and placement of drainage tube around pancreas. Twenty two patients (41.5%) developed postoperative peripancreatic abscess. The average hospitalized days (83.3±25.1 days) of the patients with peripancreatic abscess was longer than those without (22.7±14.7 days) peripancreatic abscess (Ｐ＜0.01). Six cases of 28 (21.4%) patients who had localized or scattered pancreatic necrosis developed peripancreatic abscess, 16 cases of 25 (64.0%) patients who had subtotal or total pancreatic necrosis developed peripancreatic abscess which showed significant difference between two groups (Ｐ＜0.01). Among 21 patients in whom 2 to 4 doublelumened tubes for negative presure drainage were placed,5 cases (23.8%) had peripancreatic abscess but 32 patients with only one tube placed, 17 patients (53.1%) had peripancreatic abscess, the difference between two groups were significant (Ｐ＜0.05). At least 6 patients whose drainage tubes worked badly produced postoperative peripancreatic abscess. These results indicate that the peripancreatic abscess is closely related with the severity of the disease, surgical treatment, and proper postoperative care of the drainage tubes.
In order to observe activity of tumor necrosis factor (TNF) in the serum, pancreatic histopathological damage, as well as their relationships in acute necrotizing pancreatitis (ANP), thirty five SD rats were randomly divided into 7 groups according to their sampling time with 5 in each group. ANP was induced by retrograde infusion of 5% sodium taurocholate through biliopancreatic duct in 6 experimental groups (Group B1～B6).Blood and pancreatic tissue samples were obtained at hour 0,0.5,2,4,6 or 8 respectively when the animals were sacrificed.Results showed that serum level of TNF activity rose significantly in Group B2,and reached the maximal value in Group B4.The pancreatic histopathological damage in ANP rats was getting worse along with time. Serum TNF activity had close relation to pancreatic histopathological score (r=0.63, Ｐ＜0.01),suggesting that serum TNF may play an important role in the process of deterioration of pancreatic tissue damage during ANP.
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.
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 relationship between blood glucose variability index and persistent organ failure (POF) in acute pancreatitis (AP). MethodsWe prospectively included those patients who were diagnosed with AP with hyperglycemia and were hospitalized in the West China Center of Excellence for Pancreatitis of West China Hospital of Sichuan University from July 2019 to November 2021. The patients were given blood glucose monitoring at least 4 times a day for at least 3 consecutive days. The predictive value of blood glucose variability index for POF in patients with AP was analyzed. ResultsA total of 559 patients with AP were included, including 95 cases of POF. Comparing with those without POF, patients with AP complicated by POF had higher levels of admission glucose (11.0 mmol/L vs. 9.6 mmol/L), minimum blood glucose (6.8 mmol/L vs. 5.8 mmol/L), mean blood glucose (9.6 mmol/L vs. 8.7 mmol/L), and lower level of coefficient of variation of blood glucose (16.6 % vs. 19.0 %), P<0.05. Logistic regression analyses after adjustment for confounding factors showed that the risk of POF increased with the increase of admission glucose [OR=1.11, 95%CI (1.04, 1.19), P=0.002], minimum blood glucose [OR=1.28, 95%CI (1.10, 1.48), P=0.001] and mean blood glucose [OR=1.18, 95%CI (1.04, 1.33), P=0.010]; with the higher level of coefficient of variation of blood glucose [OR=0.95, 95%CI (0.92, 0.99), P=0.021], the risk of POF decreased. The results of area under the curve (AUC) of the receiver operator curves showed that AG [AUC=0.787, 95%CI (0.735, 0.840)] had the highest accuracy in predicting POF, with sensitivities of 60.0% and specificities of 84.7%. ConclusionHigh admission glucose, minimum blood glucose, mean blood glucose, and low coefficient of variation of blood glucose were risk factors for the development of POF in patients with hyperglycemic AP on admission.
