ABSTRACT
Objective To investigate the relationship of serum resistin and pancreatic necrosis in the patients with severe acute pancreatitis. Methods Twenty-eight patients with SAP admitted to our hospital from March 2008 to November 2008 were divided into two groups according to the CT scan imaging: necrotic group and non-necrotic group. The enzyme-linked immunosorbent assay (ELISA) was used to test the serum resistin levels. An ROC curve was depicted to predict the pancreas necrosis. Results There were 21 patients in the non-necrotic group and 7 in the necrotic group, and there was no significant difference in terms of sex, age and baseline disease (P>0.05). The resitin levels ranged from 0.1730 ng/ml to 7.4923 ng/ml, with a mean (3.7102±1.6987) ng/ml. The area under the curve of resistin values was 0.884±0.108 (95%CI:0.672～1.097), asymptote signals 0.003, then it was calculated that P=0.003, which was>0.50. Conclusions The serum resistin may be of clinical value to predict the pancreatic necrosis.
ABSTRACT
Background: Resistin level is high in patients with severe acute pancreatitis (SAP), and resistin is expected to be a new marker for evaluating the severity of acute pancreatitis. Objective: To explore the influence of integrated traditional Chinese and Western medicine therapy on serum resistin levels in SAP patients. Design, setting, participants and interventions: Twenty-eight SAP patients meeting inclusion criteria from Department of Integrated Traditional Chinese and Western Medicine, West China Hospital, Sichuan University were included, and the patients were randomly divided into treatment group and placebo group. There were 13 patients in the treatment group and 15 patients in the placebo group. Patients in the treatment group were given traditional Chinese herbal medicine in addition to the conventional treatment. Patients in the placebo group were given placebo in addition to the conventional treatment. Main outcome measures: The serum resistin levels on admission, and days 1, 3, 5, and 7 after the admission were detected. Results: The serum resistin levels on admission in all the patients were higher than normal level, and there was no significant difference between the two groups (P>0.05). On days 1, 3, 5, and 7 after admission, the resistin levels in the treatment group were (3.29+/-1.66) mu g/L, (3.71+/-1.05) mu g/L, (3.08+/-1.47) mu g/L and (3.62+/-1.67) mu g/L, and in the control group (5.16+/-1.93) mu g/L, (5.07+/-1.53) mu g/L, (4.88+/-1.47) mu g/L and (5.12+/-1.48) mu g/L, respectively. The resistin levels were lower in the treatment group than in the control group (P<0.05). Conclusion: Serum resistin level in SAP patients can be decreased by integrated traditional Chinese medicine and Western medicine therapy.
ABSTRACT
OBJECTIVE: To explore the mechanism of Chaiqin Chengqi Decoction (CQCQD) in treatment of rats with acute necrotizing pancreatitis (ANP). METHODS: Thirty SD rats were randomly divided into 3 groups: sham-operated (SO) group, ANP group and CQCQD-treated group. ANP was induced by retro-pumping 3.5% sodium cholate to common bile duct. Blood sample was collected from abdominal vein for examination and the pancreatic tissue samples were taken for making pathology section 6 hours later. The pancreatic tissue (HE staining) was observed by light microscope. The content of tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6) was detected with the method of enzyme-linked immunosorbent assay, and the activation of nuclear factor-kappaB (NF-kappaB) in pancreas was detected by immunohistochemical method. RESULTS: Compared with the SO group, there was dramatic increase in the white blood cell (WBC) counts and AMY level in the ANP group (P<0.05, P<0.01). Compared with the ANP group, the WBC counts and AMY level in CQCQD-treated group were significantly reduced (P<0.05). The edema, inflammatory infiltration, haemorrhage and necrosis scores and total pathological score in the ANP group were obviously higher than those in the SO group (P<0.01). The edema, haemorrhage and inflammatory infiltration scores and the total pathological score in CQCQD-treated group were decreased (P<0.05). The integral optical density of NF-kappaB p65 positive cells of pancreas in CQCQD-treated group was lower than that in the ANP group (P<0.05). CONCLUSION: CQCQD can reduce the content of serum TNF-alpha and IL-6, depress the activation of NF-kappaB, and lessen the pancreatic lesions.
ABSTRACT
OBJECTIVE: To study the risk factors for severe acute pancreatitis (SAP) complicated by pancreatic encephalopathy (PE). METHODS: Clinical data from 255 patients with SAP from January 2005 to December 2006 were reviewed. Thirty-one SAP patients had PE, and 224 SAP patients did not. Clinical characteristics of SAP patients in both PE group and non-PE group were analyzed. RESULTS: Ranson scale and the incidence rates of acute respiratory distress syndrome (ARDS), renal failure, hypoproteinemia, hypocalcemia and hyperglycosemia in PE group were higher than those in non-PE group (P0.05). Multivariate logistic regression analysis showed that ARDS and hyperglycosemia were high risk factors. Cure rate in PE group was higher than that in non-PE group. CONCLUSION: Nosogenesis of PE is the result of multiple factors. ARDS and hyperglycosemia may be the high risk factors for PE.
