RESUMO
Objective To evaluate the efficacy and safety of transcatheter arterial chemoembolization(TACE)combined with per-cutaneous microwave ablation(MWA)in treatment of large-sized hepatic carcinoma.Methods A total of 84 patients with large-sized hepatic carcinoma were randomly and equally divided into the study group(n=42)and control group(n=42).TACE combined with MWA was carried out in the patients of the study group,while only TACE was performed in the patients of the control group.Results The effective rate of the study group and the control group was 71.4% and 42.8% respectively,and the difference between the two groups was statistically significant(P <0.05).In the study group,the survival rates at 6,12,18,24 months after the treatment were 88.1%,73.8%,52.3% and 33.3% respectively,while in the control group the survival rates were 76.2%,57.1%,30.9% and 9.5%respectively.There was no statistically significant differences in the postoperative complications between the two groups.Conclusion TACE combined with MWA appears to be an effective approach for the treatment of large-sized hepatic carcinoma.The effect of combined therapy is obviously superior to the only TACE.
RESUMO
OBJECTIVE@#To compare the ELISA and Pharmica unicap reagents of Dermatophagoides pteronyssinus specific IgG4 in clinic.@*METHOD@#The stability of ELISA reagent was studied first with parameters of intra and inter assay variations (%CV). Calibration curve of the two reagents was compared. Sixty-five serum samples before or after standardized specific immunotherapy were examined with the two methods, correlation coefficient was calculated.@*RESULT@#The stability of ELISA reagent was good with low intra and inter assay variations (3.48% and 5.78%). Calibration curve of the two reagents was similar. The correlation coefficient was 0.93 between the two test methods.@*CONCLUSION@#The results of ELISA and Pharmica unicap reagents of Dermatophagoides pteronyssinus specific IgG4 were highly consistent. The ELISA reagents could be applied in clinic.
