ABSTRACT
Objective To analyze the expression of C-reactive protein(CRP)in 2-12-year-old children with acute otitis media(AOM),we can use CRP as a strong evidence for the usage of antibiotics in the diagnosis and treatment of otitis media.Methods 250 children with AOM were selected as the research subjects.52 cases refused to test,CRP was detected in 198 children(231 ears).CRP was examined in all patients before treatment,they were followed up for 1 month.After treatment,CRP was reviewed in three days,one week and one month,respectively.Results In 198 children(231 ears),71 ears were recovered,33 ears improved,and 127 ears were ineffective in three days,the effective rate was 45.0%(104/231).100 ears were recovered,45 ears improved,and 86 ears were ineffective in one week,the effective rate was 62.8%(145/231).121 ears were recovered,56 ears improved,and 54 ears were ineffective in one month,the effective rate was 76.6%(177/231).The effective rate were significantly different among the three groops(x2=14.643、48.406,10.494,all P<0.05).Among 198 children,188 ears were in the low expression group,43 ears were in the high expression group.After three days of treatment,the composition ratio of group B and group C was changed(x2 =5.979,P=0.014),while group A had a significant change(x2 =13.948,P=0.000).Therefore,early use of antibiotics was effective in reducing CRP,so as to reduce the clinical symptoms in children.Conclusion CRP can be used to guide antibiotic monitoring.
ABSTRACT
Autoimmune hepatitis (AIH) is liver parenchymal inflammation mediated by the autoimmune response of hepatocytes. Its clinical features include elevation of aminotransferases in serum, presence of various autoantibodies in circulation, hypergammaglobulinemia, and interface hepatitis in liver tissue. Although the etiology and pathogenesis of AIH have not been fully elucidated, a consensus has been reached on the theories of "genetic susceptibility" and "molecular simulation" , and "immunoregulatory disorder" remains a hot research topic for many scholars. This article reviews the research advances in the theories of "genetic susceptibility" , "molecular simulation" , and "immunoregulatory disorder" .
ABSTRACT
Objective@#To explore effects of allogeneic hematopoietic stem cell transplantation (HSCT) in combination with infusion of endothelial progenitor cells (EPC) on bone marrow inflammatory injury.@*Methods@#6-8 weeks BALB/c (H-2Kd) mice after lethal dose of irradiation (TBI) were subjected to allogeneic bone marrow transplantation (BMT group) or co-transplantation of EPC (EPC group) . Samples of bone marrow cells of mice in each group on days 7,14,21,28 after transplantation were obtained to detect EPC cultural and cell chimeric rates by flow cytometer. Mice were sacrificed on days 7, 14, 21 and 28 post HSCT to analyze bone marrow pathology by H&E staining, the infiltration of macrophages and neutrophils by Western blot, validation expression levels of inflammatory complexes nlrp1、nlrp6 and its downstream molecules casepase-1 by Q-PCR and Western blot.@*Results@#Cell chimeric rate on day 7 after transplantation in EPC group[ (91.65±2.77) %] was significantly higher than in BMT group[ (83.69±1.26) %]. Alleviated osteomyelitis injury and inflammatory cell infiltration in EPC group were observed when compared with BMT mice. Also significant reductions of the levels of nlrp1、nlrp6、casepase-1 transcription complexes in EPC mice were noted when compared with BMT ones.@*Conclusion@#Co-transplantation of HSC and EPC could alleviate inflammatory cell infiltration and activation of the complex to promote the repair of bone marrow.
ABSTRACT

ABSTRACT
Objective To investigate the effect of Galangin of different purity on melanocyte proliferation and melanin synthesis of A375-HaCaT co-culture system. Methods The A375-HaCaT co-culture system was established with Transwell technology, and 0.1, 0.5, 1.0, 5.0, 10 μg/mL Galangin of the purity of 70%and 90%was used to act on the co-culture system. Cell proliferation, melanin content and tyrosinase of A375 were measured by MTT assay, NaOH lysis assay and L-DOPA oxidation assay respectively. The cytokines such as ET-1 and SCF in HaCaT were detected by ELISA. Results A375 cells in co-culture system grew well, and 0.1, 0.5, 1.0, 5.0, 10 μg/mL Galangin of the purity of 70% and 90% had up-regulation effect on cell proliferation, melanin content and tyrosinase of A375. Moreover, Galangin could increase the expression level of ET-1 and SCF of HaCaT at more than 0.5 μg/mL, and the effect of Galangin of 70% purity was better than 90% purity. Conclusion Galangin could promote the cell proliferation, melanin content and tyrosinase of A375, and mechanism of the pathways is probably related to the up-regulation on the expression of ET-1 and SCF of HaCaT.
