At present,research of genes and signal transduction pathway for etiology and pathogenesy of diseases is a hot topic.STAT3 signal transduction plays an important role in regulating cell proliferation,differentiation,survival and apoptosis.As a point of convergence for numerous oneogenie signaling pathways,STAT3 is constitutively activated in diverse human cancer cells.Current study suggest that activation of STAT3 signal transduction is closely related to the currence,development and malignant biological behaviors of tumor.STAT3 has been identified as a promising target for cancer treatment.

Objective To detect supernatant of SD rat bone marrow mesenchymal stem cells(BMSC)and liver cells,and explore the role of cytokines,and provide a theoretical basis for the biological artificial liver and clinical treatment of liver failure.Methods BMSCs and primary hepatocytes of SD rat were isolated.BMSCs with its third generation and liver cells by the ratio of 1∶10 were co-cultured.Hepatocytes and BMSC were treated as control group.Observation the cells′survival and morphology and analysis of cytokine after 48 h were made by RayBiotech.Results BMSC-hepatocyte in the co-culture group grow and proliferated rapidly,and hepatocyte could survive up to 14 days;while hepatocyte cultured alone,it grow slowly and survived only 9 days.Expression of BM-SC-liver cells supernatant changed obviously:interleukin 1,interleukin 6,interleukin 10 were higher than those in the control group,above 2 times,which showed significant difference (P<0.01).Conclusion Co-culture of BMSC-liver cell could induce BM-SC secrete paracrine and autocrine:IL-1 and IL-6 and IL-10,which could promote the growth of hepatocyte and extend the liver cell survival time.In-vitro BMSC-liver cells could provide biological artificial liver cell sources,as well as provide theory basis for using cytokine treatment for liver failure.

Purpose]The purpose of this thesis is to briefly study how to translate different types of anadiplosis in Yellow Emperor's Canon of Internal Medicine, so as to evoke other translators'attention in this field. [Methods] There are different types of anadiplosis in Yellow Emperor's Canon of Internal Medicine, thus this thesis first summarizes the categories of anadiplosis structure in Yellow Emperor's Canon of Internal Medicine, then studies the respective use and mixed use of domestication and foreignization strategy in translation of the three types of anadiplosis structures. Furthermore, it also analyzes the advantage and disadvantage of domestication and foreignization strategy and the scope of their application. [Results] Through research, the thesis discovered that both domestication and foreignization strategy have their own advantage and disadvantage in translating anadiplosis in Yellow Emperor's Canon of Internal Medicine. On one aspect, translators should spread as much traditional medical culture as possible; on the other hand, translators should also take readers' response into accounts. Although domestication is a major trend nowadays, with the deepening of culture exchange, foreignization will play a more important role in TCM classics translation. [Conclusion] Domestication and foreignization strategy complement each other in the translation of anadiplosis in the Yellow Emperor's Canon of Internal Medicine. However, because of the requirement to spread traditional Chinese medicine, foreignization strategy will be used more frequently than before.

Objective To research the effect of GANT61 on epithelial‐mesenchymal transition (EMT) in human lung cancer H1703 and A549 cells lines ,and to preliminarily investigate its action mechanism .Methods DMSO was used as the control(DMSO group) .After treating H1703 and A549 cells with GANT61 for 24 h ,the gene changes of Gli‐1 ,Gli‐2 ,E‐cadherin and Vimentin were detected by using the real time fluorescence quantitative PCR method .The influence of GANT61 on the expression of E‐cad‐herin and Vimentin protein after acting on H1703 and A549 cells was observed by using the Western blotting assay .The scratch healing test was performed to evaluate the effect of GANT 61 on the tumor cell invasion ability after acting on H1703 and A549 cells .Results The real time fluorescence quantitative PCR showed that ,compared with the DMSO group ,GANT61 down‐regulated the mRNA expression of Gli‐1 ,Gli‐2 and Vimentin mRNA of H1703 and A549 cell lines and elevated the expression of E‐cadherin protein(P<0 .01);the Western blotting showed that GANT61 down‐regulated the expression of Vimentin of H1703 and A549 cell lines ,and elevated the expression of E‐cadherin(P<0 .01);the scratch healing test revealed the invasion ability of H 1703 and A549 cells in the GANT61 treatment group was significantly decreased (P<0 .01) .Conclusion EMT in lung cancer is related with aber‐rant activations of Gli1 and Gli2 in Hedgehog signal transduction pathway ,GANT61 could influence the EMT ability in lung cancer cells by down‐regulating the expression of Gli‐1 and Gli‐2 .Gli could become a new molecular target for inhibiting the lung cancer cell metastasis.

ObjectiveTo explore the relationship between β2-adrenergic receptor (β2-AR) gene Arg16Gly polymorphism and essential hypertension (EH) in elder (≥60 years old).Methods150 old healthy controls and 115 old patients with EH (all of them without kin relation) were selected to test genotype of β2-AR by the technique of polymerase chain reaction-restriction fragment length polymorphism (PCR-PFLP).ResultsThe frequencies of three genotypes (Arg/Arg, Arg/Gly and Gly/Gly) were 22.81%, 53.51% and 23.68% in the EH group and 27.33%, 67.33% and 5.33% in the controls respectively. The frequencies of Arg and Gly allele were 49.56 % and 50.44% in the EH group, and 61.00% and 39.00% in the controls. There was a significant difference in distribution of alleles/genotypes between EH group and controls ( P<0.05).Conclusionβ2-AR Arg16Gly gene polymorphism is possibly associated with hypertension in this study population.

Objective:To study the HBV infection in peripheral blood mononuclear cells in mediating the role of mother -to-child transmission of hepatitis B virus.Methods: The peripheral blood mononuclear cells ( PBMCs ) in maternal and cord blood mononuclear cells ( CBMCs ) in newborns were conventionally isolated by Ficoll-Hypaque medium.The loads of HBV-DNA in peripheral blood of maternal and cord blood of newborns were both detected by PCR .Results:The clinical data showed that the positive detection rates of HBV-DNA in serum and PBMCs of pregnant women with HBeAg (+) were 100.00%( 25/25 ) and 72.00%( 18/25),and the positive detection rates of HBV-DNA in the neonatal umbilical cord blood serum and CBMCs were 60.00%(15/25) and 44.00%(11/25),respectively.There were significantly difference between HBeAg (+) and HBeAg(-) in the pregnant women (P<0.05 ).The positive detection rates of HBV-DNA in neonatal umbilical cord blood serum and CBMCs were higher in the group with high HBV loads (more than 106copies/ml) in PBMCs than those of low HBV loading group (102-103copies/ml).The significantly difference was explored between the two groups.Conclusion: Mononuclear cells can not only be infected by HBV , but also play a critical role in the intrauterine vertical transmission of HBV via the pathway transmitted from PBMCs in pregnant women to CBMCs in newborns.

Febrile seizure (FS) is the most common type of seizures in infants, toddler, and preschool children. Inlfamma-tory mediators as triggers of fever are considered to be involved in the occurrence of such seizures. There is evidence that FS is accompanied by inlfammation. The potential role of inlfammatory mediators in the development of epilepsy after long term FS has not been fully determined. In this article the inlfammatory reaction, febrile convulsion, and the occurrence of secondary epi-lepsy will be reviewed. The progress in research of the interaction among them at home and abroad will be explored.
