Accumulating studies have proved that systemic inflammation is one of the important pathophysiologic mechanisms of heart failure. This article focuses on the sources of inflammation mediators and the causes of inflammation activation in heart failure including hemodynamic changes and oxidative stress, Toll-like receptors, microbial antigens and microorganisms, endotoxin hypothesis and neurohormonal activation. Furthermore, the effects of inflammation mediators such as cytokines and chemokines on heart failure are introduced. All lead to the conclusion that heart failure is a process with complex inflammation.

Objective To evaluate the inhibition effects of shuanghuanglian injection powder and its active components on the activities of CYP1A,CYP 2D and CYP 3A in rats liver microsomes. Methods Three probe substrates including phenacetin for CYP1A,dextromethorphan for CYP2D and midazolam for CYP3A were incubated with shuanghuanglian injection powder and the active components (baicalin,phillyrin,forsythiaside A,lutin,chlorogenic acid,coffeic acid and lutiolin) in rat liver microsomes. Contents of three probe substrates were simultaneously determined by HPLC to evaluate the metabolic rates. Results Shuanghuanglian injection powder and baicalin inhibited the activities of CYP2D and CYP 3A, but didn 't affect CYP1A. The other active components showed no effect on CYP1A,CYP2D and CYP3A. Conclusion Drug-drug interactions may occur when combining shuanghuanglian powder injection with CYP2D and CYP 3A substrates and baicalin may be the effector substance responsible for the interactions.

[Objective]To study the clinical features and expressions of IL-17A,IFN-γ,and IL-10 in serum and intestinal mucosa of patients with post-infectious irritable bowel syndrome and non post-infectious irritable bowel syndrome.[Methods]44 diar?rhea-predominate IBS patients(21 with PI-IBS,23 with NPI-IBS)and 10 healthy controls were recruited in this study. Investigation questionnaires of GSRS,SAS,SDS were carried out to evaluate the gastrointestinal function,anxiety status and depression status of IBS patients. The expressions of IL-17A,IFN-γ,and IL-10 in intestinal mucosa and serum were measured by immunohistochemis?try(IHC)and enzyme-linked immunosorbent assay(ELISA).[Results]The SDS scores of NPI-IBS patients were higher than those of controls(P<0.05),and the SAS and SDS scores of PI-IBS patients were higher than those of controls(P<0.05). The GSRS, SAS and SDS scores of PI-IBS group were higher than those of NPI-IBS group(P<0.05). Compared with healthy controls,PI-IBS and NPI-IBS group showed significant rise of IL-17A,IFN-γlevels and decrease of IL-10 level in intestinal mucosa(P<0.05);In serum,the IL-17A levels were up-regulated and the IL-10 levels were decreased in PI-IBS group but not in NPI-IBS group when compared with controls(P<0.05). In intestinal mucosa and serum,IL-17A and IFN-γlevels in PI-IBS group were slightly higher than those in NPI-IBS group(P > 0.05).[Conclusion]PI-IBS and NPI-IBS patients existed various anxiety and depression. The levels of IL-17A and IFN-γ increased and level of IL-10 decreased in PI-IBS and NPI-IBS group. But the clinical symptoms and changes of cytokines of PI-IBS patients were more significant. There may exist other pathogenesis in PI-IBS but not in NPI-IBS.

BACKGROUND:Bone marrow mesenchymal stem cel s are likely to repair renal injury by differentiating into renal parenchymal cel s. OBJECTIVE:To explore the effect and mechanism of bone marrow mesenchymal stem cel s in the renal repair after mesangial proliferative glomerulonephritis. METHODS:Thirty Sprague-Dawley rats were randomized into normal group, model group and treatment group (n=10 per group). Model group and treatment group were treated with tail vein injection of mouse anti-rat monoclonal antibody Thy1.1 to prepare mesangial proliferative glomerulonephritis models. One week after modeling, rats in the treatment group were given 2×106 bone marrow mesenchymal stem cel s via the tail vein, and rats in the other two groups were given the same volume of normal saline. Two weeks after transplantation, urinary protein, urea nitrogen, creatinine levels were detected;hematoxylin-eosin staining was used for observing pathological changes of the renal tissue under microscope;and the expression of transforming growth factor beta 1 was detected by immunohistochemistry method. RESULTS AND CONCLUSION:The levels of urinary protein, urea nitrogen and creatinine as wel as the expression of transforming growth factor beta 1 in the renal tissue arranged in descending order were listed as fol ows:model group>treatment group>control group, and there were significant differences among three groups (P<0.05). In the model group, diffuse glomerular hyperplasia was observed with the presence of increased extracel ular matrix, partial glomerular sclerosis, and interstitial infiltration of inflammatory cel s;in the treatment group, glomerular hyperplasia, mesangial proliferation and inflammatory cel infiltration were al mitigated compared with the model group. Therefore, bone marrow mesenchymal stem cel transplantation may contribute to renal repair after mesangial proliferative glomerulonephritis, by inhibiting overexpression of transforming growth factor beta 1 in the kidney.
