This study aimed to assess the therapeutic effect of mannital administration on acute hemorrhagic necrotizing pancreatitis (AHNP), 28 Wistar rats were randomily divided into therapeutic group and control group after induction of AHNP by retrograde intraductal injection of 5 percent sodium taurocholate. The rats of therapeutic group received intravenous 20% mannital (1g/kg) through tail vein, once in 12 hours, until the end of experiment; control group received saline (5.0 ml/kg) with the same way. Blood of all the rats were collected from heart and the rats were killed after 96 hours. Results: lipid peroxide (LPO) in pancreatic tissue, LPO in serum, lactate dehydrogenase (LDH), alpha-1-antitrypsin (α1-AT), glutamicoxalacetic transaminase (GOT), necrotizing square of pancreatic tissue in the therapeutic group were significantly less than those in control group (Ｐ＜0.05 or Ｐ＜0.01). The damage to pancrease, heart, liver, kidney in the therapeutic group were lighter than those of the control group and the mortality was lower (Ｐ＜0.05).Conclusions: Mannital can scavenge the oxygenderived free radicals and play a therapeutic role in AHNP.
Objective To study the effects of endothelin (ET) on acute pancreatitis in rats. Methods The acute edematous pancreatitis (AEP) and hemorrhagic necrotizing pancreatitis (AHNP) model of rats were induced by cerulein and dextran-110 and endothelin-1 was administered on AEP rats via intravenous injection. Serum amylase, plasma ET and 6-Keto-PGF1α, pancreas hostologic observation were determined. Results The serum concentration of amylase increased markedly in AHNP rats, and there was a significant difference between AHNP and AEP (Ｐ＜0.01). A dose of extrinsic ET-1 may induce the conversion of AEP to AHNP in rats. The degree of pancreatic damage correlates positively with the level of the plasma ET. Conclusion Endothelin might take part in the development of acute pancreatitis, and play a key role in the conversion of AEP to AHNP.
The aim of this study was to investigate the role of tumor necrosis factor (TNF), interleukin-6(IL-6), C-reactive protein (CRP) in pancreatitis and its systemic complications. Thirty six patients with acute pancreatitis were studied, 12 with mild disease, and 24 severe disease, of whom 9 developed systemic complications. TNF, IL-6, CRP in these patients with pancreatitis was assessed during the first, 4th, 8th days of admission. The serum concentration of TNF, IL-6, CRP were significantly increased, and significantly higher in complicated group than in mild group and severe group. These findings suggest that proinflammatory cytokines play a central role in the pathophysiology of the disease, the host systemic response to pancreatic inflammation and the level of the response did relate to the development of organ dysfunction.
Objective To investigate a new way for the treatment of severe acute pancreatitis (SAP). Methods The clinical data of 59 cases of SAP were analyzed, and they were divided into two groups: LAI group and control group. In LAI group, 30 cases were treated mainly by local arterial infusion (LAI). In control group, 29 cases were treated by intravenous infusion. Results Compared with control group, the results of LAI group were much better in abdominal pain relief, recovery of intestinal function, reducing the complications, shorter antibiotictime, decreasing the incidence of secondary systemic infection. The mortality of SAP class Ⅱ in LAI group and control group were 35.71% and 66.67% respectively. Conclusion LAI is a new way for the treatment of SAP.
Integrated traditional Chinese and Western medicine has been used to treat acute pancreatitis (AP) for more than 50 years. It has become a dominant and specialized disease treated by integrated traditional Chinese and Western medicine. After many years of clinical practice, a relatively mature and complete treatment system has been formed. Therefore, it was proposed by the Chinese Society of Integrated Traditional Chinese and Western Medicine, the Chinese Medical Association, and the Chinese Association of Traditional Chinese Medicine to update and formulate the “Guidelines for the Diagnosis and Treatment of Acute Pancreatitis with Integrated Traditional Chinese and Western Medicine” (2021) group standards in 2022, and “Integrated Traditional Chinese and Western Medicine Practice Guidelines for Diagnosis and Treatment of Acute Pancreatitis” finally published. The guideline condenses 25 kinds of important clinical issues, which guide to explain the diagnosis and treatment of AP in detail, focusing on the integration of traditional Chinese medicine and Western medicine in the management of AP, such as staging and syndrome differentiation, early fluid therapy, pain management, and organ function support in early stage. The advantages and the timing of early intervention of traditional Chinese medicine in AP are emphasized. This guideline also proposes suggestions on nutritional support, management of causes, treatment of late local complications and infections, as well as prevention of recurrence and follow-up strategies for long-term complications. This paper provides an interpretation of this guideline.
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.
Objective To evaluate the predicted value of APACHEⅡ score at admission for deep fungal infection（DFI） in patients with severe acute pancreatitis （SAP）.Methods The clinical data of 132 patients with SAP from January 2006 to June 2011 in our hospital were analyzed retrospectively. The receiver operating characteristic curve （ROC） was used for evaluating the predicted value.Results Thirty-nine patients with SAP infected DFI （29.5%）,of which 36 patients （92.3%） infected with Candida albicans,2 patients （5.1%） with Candida tropicalis,1 patient （2.6%） with pearl bacteria.And,among these 39 patients,27 patients （69.2%） infected at single site,12 patients （30.8%） infected at multi-site. The APACHEⅡ score in 39 patients with DFI was higher than that of 93 patients without DFI （17.1±3.8 versus 9.7±2.1, t=14.316,P=0.000）.The ROC for APACHEⅡ score predicting DFI was 0.745（P=0.000）, 95%CI was 0.641－0.849.When the cut off point was 15,it showed the best forecast performance,with specificity 0.81, sensitivity 0.72,Youden index 0.53. Conclusions The APACHEⅡ score at admission can preferably predict DFI in patients with SAP； when the APACHEⅡ score is greater than 15,it prompts highly possible of DFI,so preventive anti-fungal treatment may be necessary.
Eighty two cases of acute gallstone pancreatitis on early operation are reported and the significance of the clinical picture and pathology are analysed. The data showed that gallstone was found in 85.5%, among the cases of them mulliple gallstone was 71.1%, dilated cystic duct was 26.4%, common bile duct stone 36.8%, distal bile ductal stricture was found in 9.3%, and anomalous conjunction of biliary and pancreatic duct was 20.1%. Sixteen cases with serious pancreatitis were determined on operation, but death rate was 3.7% only. The authors claim that early operation may be of value in patients of acute gallstone pancreatitis with or without jaundice espesially in bile duct obstruction.
Objective To investigate the effect of nitroglycerin on preventing post-endoscopic retrograde cholangiopancreatograph (ERCP) pancreatitis (PEP) and hyperamylasemia. Methods One hundred patients diagnosed as common bile duct stones by CT or MRI and planned to undergo ERCP, EST and stones removal under endoscopy were selected from January to December 2008 in Shandong Jiaotong Hospital. These patients were randomly divided into 2 groups: nitroglycerin group (n=50), in which 0.5 mg nitroglycerin was given sublingually in 5-10 min before ERCP; control group (n=50), in which no nitroglycerin was given. The levels of serum amylase of all the patients before ERCP and at 3 h, 24 h after ERCP were detected and the incidence of hyperamylasemia and PEP were also observed. Results The level of serum amylase between 2 groups before ERCP was not significantly different (P＞0.05). The levels of serum amylase at 3 h and 24 h after ERCP were significantly higher than that before ERCP in 2 groups. The level of serum amylase in nitroglycerin group were respectively lower than that in control group at 3 h and 24 h after ERCP 〔3 h: (108.88±152.07) U/L vs. (196.30±244.41) U/L; 24 h: (97.02±113.38) U/L vs. (234.22±406.05) U/L〕， P＜0.05. The incidence of hyperamylasemia (12.00%, 6/50) and PEP (2.00%, 1/50) in nitroglycerin group was respectively significantly lower than that in control group (hyperamylasemia: 30.00%, 15/50; PEP: 14.00%, 7/50）， P＜0.05. Conclusion Sublingual nitroglycerin can decrease the level of serum amylase and prevent PEP and hyperamylasemia.
Objective To study the clinical protective effect of hemoperfusion combined with hemofiltration on inflammatory reaction of hyperlipidemia severe acute pancreatitis (HLSAP). Methods Thirty-seven patients with HLSAP treated between January 2012 and December 2014 were selected and divided into three groups based on different treatments. Thirteen patients were allocated into hemoperfusion combined with continuous veno-venous hemofiltration group (HP+CVVH group) and treated with hemoperfusion combined with hemofiltration; 11 patients were allocated into continuous veno-venous hemofiltration group (CVVH group) and treated with hemofiltration; and all the other patients were allocated into control group and treated with conventional treatment. The levels of blood triglyceride, C-reactive protein, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-8 (IL-8) and acute physiology and chronic health evaluation (APACHE)Ⅱ score of the patients after treatment were observed. The hospital stay, organ dysfunction rate and mortality of the patients were measured. Results Compared with the control group, the levels of blood triglyceride, C-reactive protein, TNF-α, IL-6, IL-8 and APACHE Ⅱ score of the patients in the HP+CVVH group and CVVH group were both significantly reduced 72 hours after therapy (P<0.05). However, the levels of blood triglyceride, C-reactive protein, TNF-α, IL-6, IL-8 and APACHE Ⅱ score of the patients in the HP+CVVH group were significantly lower than those in the CVVH group at the same time point (P<0.05). The hospital stay of the patients in the HP+CVVH group and CVVH group was significantly shorter than that in the control group (P<0.05). Compared with the CVVH group, the hospital stay of patients in the HP+CVVH group was significantly shorter (P<0.05). There was no statistical difference in organ dysfunction rate and mortality among the three groups (P>0.05). Conclusion Hemoperfusion combined with hemofiltration is an effective method for HLSAP by cleaning the inflammatory mediators availably and inhibiting the excessive inflammatory reaction.
