ABSTRACT
<p><b>OBJECTIVE</b>To construct and analyze the differential expression profiles of microRNAs (miRNA) and mRNA in oral squamous cell carcinoma (OSCC). To explore the miRNA and mRNA of OSCC development and progression.</p><p><b>METHODS</b>The differential expression profiles of miRNA and mRNA were built by high-throughput deep sequencing technology. Using Gene Ontology (GO) enrichment analysis, the roles of differentially expressed miRNA and mRNA in cell cycle, cell proliferation, cell differentiation and cell apoptosis were analyzed.</p><p><b>RESULTS</b>Seventy-seven differentially expressed miRNA and 1 298 differentially expressed mRNAs were identified in OSCC. GO analysis showed that 73 miRNA had found target mRNA in cell cycle, cell proliferation, cell differentiation and cell apoptosis of OSCC. Moreover, a miRNA could regulate multiple mRNA.</p><p><b>CONCLUSION</b>The differential expression profiles of miRNA and mRNA have close relationship with the development and progression of OSCC.</p>

Objective To explore the efficacy and side effect of inductive chemotherapy with lowdose,cytarabine,homoharringtonine and granulocyte colony-stimulating factor(CHG) in elderly acute myeloid leukemia(AML). Methods Thirty-five elderly patients (age＞60 years) with AML were enrolled for the initial treatment with CHG regimen,The CHG regimen consisted of cytarabine 10 mg/m2 per 12 h by subcutaneous injection,days 1-14,homoharringtonine 1 mg/m2 per day by intravenous continuous infusion,days 1-14,and G-CSF 200 μg/m2 per day by subcutaneous injection 12 h before chemotherapy,days 0-14. G-CSF only was used when white blood cell count(WBC) was less than 20×109/L during the whole course. Results After the first course,12 patients achieved complete response (CR),15 patients achieved partial response(PR),and 8 patients had no response(NR). After the second course,5 of 15 PR patients achieved CR,2 of 8 NR patients achieved PR. The total effective rate was 82 % (29/35). Of those 17 CR patients,eleven patients continued maintenance therapy and remained in remission for 12-34 months with a median CR duration of 18 months,the other 6 patients relapsed and were treated with original regimen,including one achieved CR again,4 achieved PR,and 1 achieved NR. The CHG regimen had mild hematologic toxicities and no severe nonhematologic toxicities. Conclusion CHG regimen is effective and well tolerated in remission for elderly AML.
ABSTRACT
In the current work, the fusion gene including somatostatin (SS) and the hepatitis B surface antigen gene was cloned into a balanced lethal system plasmid (pYA3493), and then transformed into asd- attenuated Salmonella choleraesuis C500 strain, the positive transformant without antibiotic resistance gene was confirmed by restriction analysis and DNA sequencing, designated as pYA-SS. The expression and immunogenicity of fusion protein were detected by SDS-PAGE and Western blot analysis. These results show that the recombinant prokaryotic expression plasmid pYA-SS could express the SS fusion protein with good immunogenicity in C500 strain. In above all, this study could provide reliable materials to develop novel, good and safe vaccine in enhancing the growth of animals.
