ABSTRACT
Acute-on-chronic liver failure (ACLF) is a common critical and severe syndrome in patients with chronic liver diseases in China and other countries in the Asia-Pacific region. In recent years, both the Eastern and Western experts have defined ACLF as a new type of liver disease manifesting as a high 28-day mortality rate (>30%) and extensive systematic inflammatory response. ACLF has become a hot topic in the field of liver diseases. This article reviews the research advances in the definition and etiological spectrum of ACLF and discusses the inspirations of such new knowledge for future research.
ABSTRACT
Objective:To observe the effects of Shexiang Baoxin Pill (SBP) on isoprenaline (Iso)-induced changes in myocardial cell volume,shape,and connexin 43 (Cx43) expression.Methods:HgC2 myocardial cells were randomly divided into a control group,a Iso group and a Iso+SBP group.After 72 h of culture,the average surface area of HgC2 cells was measured under phase contrast microscope.Bicinchoninic acid (BCA) protein assay was carried out to determine the concentration of proteins.The survival rate of myocardial cells was measured by methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay,and the Cx43 expression was detected by Western blot.Results:The mean surface area and Cx43 concentration in Iso-treated myocardial cells were increased under the phase contrast microscope (P<0.05).Compared with the Iso group,the mean surface area was decreased,and the Cx43 concentration was reduced in the Iso+SBP group (both P<0.05).Compared with the control group,the Cx43 expression was obviously down-regulated in the H9C2 cells of the Iso group (P<0.05);while compared with the Iso group,the Cx43 expression was obviously up-regulated in the Iso+SBP group (P<0.05).Conclusion:Shexiang Baoxin Pills can prevent Iso-induced myocardial hypertrophy and down-regulate Cx43 expression.
ABSTRACT
AIM To observe the therapeutic effects of Shengjiang Xiexin Decoction (Zingiberis recens Rhizoma,Zingiberis Rhizoma,Coptidis Rhizoma,etc.) on irinotecan (CPT-11)-induced delayed diarrhea in colorectal carcinoma mice and to discuss its possible action mechanism.METHODS The AOM/DSS-induced female colorectal carcinoma mice were randomly divided into normal group,model group and Shengjiang Xiexin Decoction group.The Shengjiang Xiexin Decoction group was intragastrically administered with Shengjiang Xiexin Decoction,the normal group and the model group were intragastrically administered with normal saline.The diarrhea index and rectum pathologic morphology were measured,and the β-glucuronide activity,IL-15 content and UGT1A1 expression were detected.RESULTS The diarrhea index of Shengjiang Xiexin Decoction group was significantly lower than that of the model group,which might be related to the significant inhibition of β-glucuronide activity,and sig-nificant improvement of IL-15 content and UGT1A1 expression.CONCLUSION Shengjiang Xiexin Decoction shows therapeutic effects on irinotecan-induced delayed diarrhea in AOM/DSS-induced colorectal carcinoma mice.
