Objective:To observe the general status, the effect of resisting to the aggression of FBL-3 cells and protective immunity of the mice by using leukemia vaccine during the immune reconstitution.Methods:The immune deficiency C57BL/6 mice induced by total body irradiation were reconstituted immunity with homologous splenic lympocytes.The mice were immunized by injecting FBL-3 cells subcutaneously,and then attacked by using FBL-3 cells 7days thereafter.The activities of mice,the percentage of carcinoma formation and the growth status of tumor were observed.The amount of IFN-? in peripheral blood was determined by ELISA to evaluate the magnitude of cell immunity.The condition of cell infiltration in tumor central region and its periphery region was explored by patologic-section.Results:Immune reconstitution could obviously elevate protective immunity on the basis of using vaccine,and the amount of IFN-? was obviously higher.The FBL-3 tumors inoculated thereafter grwe slowly,and significant infiltration of mononuclear cells peri-tumor as well as necrosis of tumor cells were observed.Also,the life time of the mice was prolonged.Conclusion:Immune reconstitution and vaccine can significantly elevate protective immunity

Objective To observe the efficacy of HAG regimen in remission inductive treatment for elderly patients with acute myeloid leukemia (AML) and myelodysplastic syndrome-refractory anemia with excess blasts (MDS-RAEB). Methods The clinical features of 21 cases with AML and 9 cases with MDSRAEB (≥60 year old) treated with HA-G regimen in remission induction were retrospectively analyzed,including the complete remission (CR) rate, efficiency rate as well as their toxicities. Results In 21 elderly patients with AML treated with HAG regimen, the efficiency rate was 66.7 % (14/21), CR rate 47.6 % (10/21).In 9 elderly patients with MDS-RAEB, the CR rate was 55.6 % (5/9). The main toxicity of HA-G regimen was infections secondary to hematopoiesis suppression after chemotherapy. All patients were well tolerated to adjusted regimen. Conclusion The HA-G regimen is much effective in remission induction for elderly patients with AML and MDS-RAEB.

Objective To assess the value of real-time myocardial contrast echocardiography (RTMCE) and intermittent triggered myocardial contrast echocardiography (ITMCE) in the detection of myocardial no-reflow phenomenon after reperfusion in acute myocardial infarction on mini-swine models. Methods Thirty close-chest mini-swines were used to create acute myocardial infarction and reperfusion model through interventional method. RTMCE and ITMCE were performed at baseline, 2 h after occlusion of left anterior descending coronary artery and 3 h after reperfusion. The myocardial perfusion defects after occlusion was measured as risk area (RA) and that after reperfusion was measured as no-reflow area (NRA). NRA/RA was calculated and compared with pathological findings. Results The whole study protocol was successfully performed in 27 mini-swines. NRA/RA obtained from RTMCE, ITMCE and pathological staining was (47.94±21.29)%, (38.20±21.04)% and (30.07±14.62)% , respectively. NRA/RA had no significant difference by ITMCE and pathological staining (P=0.124), RTMCE and ITMCE (P=0.071). The correlation coefficient of RTMCE and staining was 0.700 (P<0.001), ITMCE and staining was 0.765 (P<0.001), RTMCE and ITMCE was 0.897 (P<0.001). The sensitivity, specificity and accuracy in the detection of myocardial no-reflow was 100%, 58.33% and 79.17% for RTMCE, 91.67%, 73.33% and 81.48% for ITMCE. Conclusion Both RTMCE and ITMCE could be used as noninvasive methods to reveal the myocardial perfusion and quantitatively detect myocardial no-reflow after reperfusion therapy.
