The link between nonresolving inflammation and cancer is well documented. On the one hand, epidemiologic evidence supports that approximately 25% of all human cancer worldwide is caused by nonresolving inflammation. On the other hand, inflammatory cells are found in the microenvironment of most, if not all, tumors. In the tumor micro-environment, inflammatory cells and molecules influence almost every aspect of cancer. MicroRNAs (miRNAs) participate in the initiation and progression of nonresolving inflammation-related cancer by regulating the key genes and related signaling pathways. Further investigation into the molecular mechanisms by which miRNAs carry out their functions will be of great value in the prevention, early diagnosis, and treatment of tumors.

OBJECTIVETo investigate the relation of hepatitis B surface antigen (HBsAg) level with chronic hepatitis B (CHB) and liver inflammation and fibrosis.

METHODSA total of 301 patients who diagnosed CHB and underwent liver biopsy were enrolled into the study. Meantimes, the biochemical markers, ferritin (FERR), serum HBsAg and HBV DNA quantitation were detected. The relation between HBsAg level and liver pathology were determined by spearman rank correlation analysis. The receiver operating characteristic curve was used to evaluate the accuracy of HBsAg level for liver inflammation and fibrosis.

RESULTSThe body mass index (BMI), age, gender, genotype and family history had no effective on liver inflammation and fibrosis (P < 0.05). With the progressing of inflammation and fibrosis, the serum AST and ALT raise obviously (chi2 = 71.193, 96.344, 47.847, 63.981; P = 0.000, 0.000, 0.000, 0.000). When fibrosis reached to S4, the level of HBV DNA decreased obviously (chi2 = 33. 322; P = 0.000). With the aggravation of inflammation and fibrosis, the serum HBsAg gradually descended (chi2 = 68.173,15.719; P = 0.000, 0.000). The areas under operating characteristics curves of HBsAg predicted < or = G3 and < or = S3 were 0.732 and 0.793, and the specificity were 0.778, 0.891, and sensitivity were 0.685, and 0.633, respectively.

CONCLUSIONThe level of HBsAg of Chinese CHB patients descended gradually with the aggravation of liver inflammation and fibrosis. The serum HBsAg had a higher specificity to predict < or = G3 and < or = S3 of CHB patients. But there had superiority of predicting fibrosis than inflammation.

OBJECTIVETo study single wall carbon nanotubes (SWCNT) and its role in inducing inflammatory cytokines in the cruor-fibrinolysis system of rat.

METHODSTwenty one Wistar rats were divided into four groups: 1) control; 2) low-dose SWCNT (0.15 mg/kg BW); 3) medium-dose SWCNT (0.75 mg/kg BW); 4) high-dose SWCNT (1.5 mg/kg BW). Intratracheal instillation of SWCNT suspensions was administered to rats once per day for 21 days. In order to assess the exposure effect of SWCNT to the rats, activity of Inflammatory cytokine was measured and markers of cruor-fibrinolysis system were studied via ELSIA. Also, change in clotting time was recorded and histopathology was studied.

RESULTSIL-6 and IL-8 concentrations of rats exposed to SWCNT were significantly higher than those in controls (P<0.05). The activity of inflammatory cytokines and histopathological change indicated that oxidative damage occurred. Change in clotting time in rats exposed to SWCNT decreased compared with controls. Meanwhile, t-PA (tissue-tupe plassminogen activator) and AT-III (antithrombin-III) levels in rats exposed to particulates increased or decreased significantly compared with controls (P<0.05). A similar trend was observed for D-dimer (D2D) levels, indicating that SWCNT can impact the cruor-fibrinolysis system of rat.

CONCLUSIONThe results from our study suggest that an increased procoagulant activity and reduced fibrinolytic activity in rats exposed to SWCNT can cause pulmonary oxidative stress and inflammation, due to the release of pro-thrombotic and inflammatory cytokines into the blood circulation of rat.

In trauma, infection and hemorrhagic shock derived stress, primary and secondary injury may result in severe derangement in the internal environment. The abnormal changes of immune-mediated inflammation interfere its pathogenesis and development directly. In recent years, various aspects of neuroendocrine responses, especially the regulatory effects of hypothalamic-pituitary-adrenal and sympathetico-adrenomedullary axes in inflammatory diseases have been the focus of research. Most importantly, corticotropin-releasing hormone (CRH) acts as a key player in the regulation of interactions between neuroendocrine and immunity both directly and indirectly. The paper summarized the recent development of CRH in the immune-mediated inflammation.
