RESUMO
Objective To observe the clinical effect of therapy of budesonide/formoterol powder for inhalation in treatment of adult with bronchial asthma.Methods 90 cases with bronchial asthma and were divided into observation group and control group randomly from February 2014 to February 2015.45 cases in each group.Control group was treated with budesonide inhalants +formoterol inhalants, observation group was given budesonide/formoterol powder inhalation.Changes of related indicators were followed up and recorded.Results After treatment, IL-5, IL-12 and IFN-γwere (60.2 ±9.7)pg/mL,(31.4 ±3.1)pg/mL,(1.6 ±0.2) ng/mL of observation group were better than control group (72.8 ±10.7)pg/mL,(38.5 ± 5.6)pg/mL,(2.3 ±0.3) ng/mL (P<0.05).After treatment,total effective rate in observation group was 68.9%, which was better than control group (48.9%)(P<0.05).Conclusion Clinical effect of budesonide/formoterol powder for inhalation in treatment of patients with bronchial asthma is accurate, and there is no obvious adverse reaction.
RESUMO
Bispecific antibodies have been exploited as both cancer immunodiagnostics and cancer therapeutics, which have shown promises in clinical trials in cancer imaging and therapy. To improve the anti-tumor effect, an scDb (bispecific single-chain diabody) was constructed from the variable domain genes of two scFvs (single-chain variable fragment antibodies) directed against human EGFR (epidermal growth factor receptor) and VEGFR2 (vascular endothelial growth factor receptor 2) extracellular domains. The anti-EGFR/ anti-KDR scDb was constructed into pHEN2 plasmid and expressed in Escherichia coli HB2151 host. After purification by one-step affinity chromatography of IMAC, scDb protein was characterized by Western blotting. The yield of scDb protein was 570 microg per liter medium. scDb bound to EGFR as efficiently as the parental antibody scFv-E10, while a little bit weaker than the parental antibody scFv-AK404R when bound to KDR. In conclusion, the scDb protein could bind both EGFR and KDR specifically and could be applied for further anti-tumor research.
