The cloning of promoter is important for studying the genetic engineering and the regulation of gene expression in plants. Two promoters Os772 and Os359, which are predicted to be highly expressed in the endosperm of rice from the EST database were cloned. After construction of the Os772∶∶GUS and Os359∶∶GUS expression vectors, they were transformed into rice. X-Gluc staining of transgenic plants showed that Os772 and Os359 can promote GUS gene expression in matured endosperm but not in root, stem, leaf and flower. This result indicates Os772 and Os359 are two rice endosperm-specific promoters.

Objective To evaluate the effect of cytokine-induced killer cells (CIKs) as an adoptive immunotherapy option for treatment of leukemia relapse after allo-hematopoietic stem cell transplantation (allo-HSCT).Methods Two cases of infusion of donor CIKs in patients with leukemia relapse after allo-HSCT were retrospectively analyzed.Patient one relapsed 986 days (+986d) after HLA-matched unrelated donor allo-HSCT.Applications of chemotherapy only resulted in short term remission,but allo-CIKs were successfully expanded from the patient's peripheral blood mononuclear cells of donor origin.Totally five cycles of CIKs infusion were infused as an alternative of adoptive immunotherapy.Patient two had recurrent in the + 158d after HLA-matched sibling alloHSCT.At + 204d and + 294d,two cycles of CIKs which were expanded from donor peripheral blood mononuclear cells were infused.Results One cycle of CIKs was given to patient one after the application of chemotherapy to reduce the tumor burden,and the patient successively achieved complete remission.Again after additional four cycles of CIKs infusion,consistent remission was maintained during the following seven months.Patient two who had relapsed disease posttransplantation,achieved cytological complete remission after withdrawal of immunosuppressants and undergoing chemotherapy combined with G-CSF mobilized stem cell infusion.However,at + 187d,the patient suffered from side-effect of acute graft versus host disease and extramedullary infiltration.The symptoms were alleviated markedly after one cycle of CIKs infusion at + 204d.Moreover,the pain disappeared after an additional infusion at + 294d.And up to the present,the bone marrow aspiration showed complete remission while the extramedullary disease vanished.Conclusion The use of CIKs in the treatment of leukemia relapse after allogeneic bone marrow transplantation can be feasible and well tolerated.

Objective To explore the change of Doppler velocity waveforms in the fetal main pulmonary artery in patients with early onset severe preeclampsia and to assess its value in fetal lung maturity.Methods A prospective study was conducted to analyze fetal main pulmonary artery velocity waveforms parameters including acceleration time(AT),ejection time(ET),acceleration time/ejection time (AT/ET),peak systolic velocity (PSV) in 30 cases of pregnant women with early onset severe preeclampsia.According to neonatal outcome,these cases were divided into respiratory distress syndrome (RDS) group (18 cases) and non-RDS group (12 cases).Each group was compared with 54 cases and 36 cases that were normal and had corresponding gestational age separately.Doppler parameters were compared between these two groups and their corresponding normal control groups.Results Gestational age at sonographic examination,gestational age at delivery and birth weight of neonates in RDS group were significantly lower than those in non-RDS group(all P <0.001).The value of AT,ET,AT/ET,PSV were lower in RDS group than those in gestational age-matched control group(all P <0.05),while there were no significant difference between non-RDS group and gestational age-matched control group(all P > 0.05).Conclusions Doppler ultrasound monitoring fetal main pulmonary artery velocity waveforms to evaluate fetal lung maturity in patients with early onset severe preeclampsia has clinical application value.
