Effect of Guo Qing Yi Tang combined with Western medicine cluster therapy on acute pancreatitis.

BACKGROUND: This study evaluated the effect of Guo Qing Yi Tang (GQYT) combined with Western medicine cluster therapy on acute pancreatitis (AP). METHODS: A total of 138 AP patients were recruited and divided into the observation group (68 patients) and control group (70 patients). The control group was treated with cluster therapy alone, while the observation group was treated with trans-jejunum feeding of GQYT combined with cluster therapy. Blood samples were taken before the treatment and 24 h, 72 h, and 1 week after the treatment. The serum concentrations of Di amine oxidase(DAO), Endotoxin(ET), D-lactic acid, Intestinal trefoil factor(ITF), MFG-E8, TNF-α, IL-1ß, IL-6, and IL-8 were determined by using spectrophotometry and enzyme-linked immunosorbent assay. The concentrations of urinary lactulose and mannitol (L/M) were determined by high-performance liquid chromatography, and the urinary L/M value was calculated. RESULTS: Compared with the control group, the observation group had shorter hospital stay, faster recovery, significantly lower APACHE II score, and higher complete response rate (94.12%) after 1 week of treatment (P < 0.05). Moreover, the indicators related to intestinal mucosal barrier function (DAO, MFG-8, L/M) and inflammatory cytokines (TNF-α, IL-6, IL-8) were significantly reduced in the observation group after 1 week of treatment (P < 0.05). CONCLUSION: GQYT combined with cluster therapy for the treatment of AP has definite curative effect and rapid onset, reduces the level of inflammatory factors, and improves intestinal mucosal barrier function and APACHE II score. Thus, it has obvious clinical therapeutic advantages and can be used as a new therapeutic regimen for AP.

Chinese herbal preparation Qing Yi TangⅡgranule protects against ex-perimental acute pancreatitis in mice / 中国病理生理杂志

[ ABSTRACT ] AIM: To investigate the protect effect of Chinese herbal preparation, Qing Yi TangⅡgranule (QYT), on acute pancreatitis (AP) mice and its mechanism.METHODS:Adult male and female C57BL/6 mice (n=24) were randomly divided into control group, AP group and AP+QYT group.Severe AP was induced by combined intra-peritoneal injection of caerulein (50μg/kg) and lipopolysaccharide (LPS;10 mg/kg).Drinking water or 24%QYT solu-tion was given to the mice in AP group or AP+QYT group by oral gavage.The mice in control group were intraperitoneally injected with equivalent volume of normal saline and gavaged with water.The mice were sacrificed 3 h after the last injec-tion.Severity of AP was assessed by biochemical markers and histology.The plasma level of IL-6 and MCP-1, and lung myeloperoxidase ( MPO) levels were determined for assessing the extent of systemic inflammatory response.The intestinal microflora, T lymphocytes and T-lymphocyte subgroups were examined for assessing the function of the intestinal barrier. RESULTS:Compared with control group, the mice in AP group presented significant increases in pathological histological scores, plasma amylase activity and IL-6 and MCP-1 levels, as well as the MPO activity in the lung and pancreatic tissues. QYT attenuated these changes to some extent.Furthermore, the increased intestinal microflora was significantly reversed by QYT.No difference of the numbers of Peyer’ s patches in small intestine in the 3 groups was observed, but the percentage of CD3 +T lymphocytes decreased significantly in AP group, and increased percentage of CD4 +and CD4 +/CD8 +ratio were found in AP group and AP+QYT group.CONCLUSION: QYT protects against cearulein and LPS-induced acute pancreatitis in mice.The mechanisms may be related to the suppression of the inflammatory response, promoting intestinal bacteria removal, and regulating the functions of T lymphocytes in the intestinal barrier.

The effect of Qing Yi Tang on bacterial and endotoxin translocation from intestine in acute hemorrhagic necrotizing pancreatitis in rats / 中国普通外科杂志

Objective To study the effect of Qing Yi Tang(QYT) on bacterial and endotoxin translocation from intestine in acute hemorrhagic necrotizing pancreatitis(AHNP) in rats.Methods SD rats were randomly divided into 3 groups: AHNP group,AHNP +QYT treatment group and sham operation(SO) group.AHNP models were set up in the former two group,while the pancreas was only mobilized in SO group.After setting up the model,QYT was gavaged in the QYT group,while normal saline was gavaged in the SO group and AHNP group.The concentration of endotoxin(ET) and the DNA of E.coli expressoin in portal vein blood in three groups of rats were measured 24h later.Results The concentration of ET and amount of E.coli DNA in portal vein of QYT group were lower than those of AHNP group.Conclusions QYT can reduce significantly the concentration of ET and E.coli DNA in portal vein blood and decrease bacterial and endotoxin translocation from intestine in the AHNP rats.
