Objective To investigate the infectious complications after nonmyeloablative allogeneic peripheral blood stem cell transplantation (NASCT). Methods Ten patients with leukemia received NASCT from HLA-identical or 1-3 antigen mismatched sibling donors with conditioning regimens of Flu/Cy+BU+ALG. Five patients were acute leukemia (AL) and all of them is in complete remission (CR1). Cyclosporine in combination with methotrexate was administered for GVHD prophylaxis. Results WBC recovered to more than 0.5 ?10 9/L during postoperative 10 day to 38 day and platelet recovered to more than 20?10 9/L during postoperative 8 day to 16 day. Bacterial infections occurred in 3 patients (30 %) and cytomegalovirus (CMV) infections in 2 patients (20 %). Varicella zoster virus (VZV) infections occurred in one patient (10 %). No fungal infections were documented. No patients died as a result of infection . Conclusion NASCT is a safe and effective therapeutic method for leukemia. It reduces acute GVHD,regimen-related toxicity and early neutropenia associated with traditional allo-HSCT.

The experiment included three potassium levels (K0 0 g x kg(-1), K1 0.33 g x kg(-1), K2 0.67 g x kg(-1)) and two water gradients (well watered and drought stress), then measured growth indicators, SOD, POD, CAT activities and concents of osmotic regulation substances. To explore the effects of K fertilizer and water on growth and physiological characteristics of Isatis indigotica, providing reference for improving drought resistance of I. indigotica. The result showed drought stress inhibited the growth and decreased the biomass of I. indigotica but K fertilizer can alleviate the drought stress. Compared with K0 treatment, K1, K2 treatment increased the biomass of overground part of by 89. 13% ,60. 87% under drought stress. The corresponding increase in soluble sugar content was 16.67%, 5.00%, and in proline content was 42.41%, 65.62%, respectively. SOD,POD and CAT activities was significantly improved in K1, K2 treatment in comparison with K0 treatment under drought stress, but soluble protein content significantly reduced. The conclusion is that appropriate amount of K fertilizer can increase the activities of antioxidase and the content of osmoregulation substance under drought stress, and improve drought resistance of I. indigotica.

Integrating visualization toolkit and the capability of interaction, bidirectional communication and graphics rendering which provided by HTML5, we explored and experimented on the feasibility of remote medical image reconstruction and interaction in pure Web. We prompted server-centric method which did not need to download the big medical data to local connections and avoided considering network transmission pressure and the three-dimensional (3D) rendering capability of client hardware. The method integrated remote medical image reconstruction and interaction into Web seamlessly, which was applicable to lower-end computers and mobile devices. Finally, we tested this method in the Internet and achieved real-time effects. This Web-based 3D reconstruction and interaction method, which crosses over internet terminals and performance limited devices, may be useful for remote medical assistant.

Phosphoethanolamine N-methyltransferase (PEAMT) is a key enzyme that catalyzes the synthesis of phosphocholine, which is an important precursor of phosphatidylcholine and glycine betaine. A 1249bp 5'-flanking region of phosphoethanolamine N-methyltransferase gene was isolated by anchored PCR, based on the cDNA sequence of PEAMT from halophyte Salicornia europaea. The transcription start site was identified as A and localized at 301bp upstream of the ATG according to the results of RLM-RACE. In SePEAMT promoter region, many potential cis-acting elements were predicted by PlantCARE and PLACE programs. Aside from the basal transcriptional elements TATA-box and CAAT-box, some stress-responsive motifs such as ABRE, HSE and LTR were found. In addition, some pollen-specific activation-related elements were also present in this region. Binary expression vector was constructed by fusing SePEAMT promoter with GUS gene and designated as pPro. The pPro was transferred into tobacco by Agrobacterium-medicated transformation and transient GUS expression analysis indicated that SePEAMT promoter could drive strong GUS expression.

Aim To evaluate the effect of intermedin (IMD)on cell proliferation and regeneration in rat tu-bular epithelial cell line (NRK-52E)that was subjec-ted to hypoxia-reoxygenation (H/R)injury.Methods The NRK-52E cells were divided into control group and three model groups (H/R,H/R +primitive vec-tor,H/R +IMD vector).The content of LDH was de-tected to observe the influence of IMD on H/R injury. The cell proliferation was detected by MTT.The cell cycle was detected by flow cytometry.Real-time PCR and western blotting were used to determine mRNA and protein levels.Results ① In comparison to the con-trol,H/R treatment decreased the cell viability and in-creased LDH activity (P <0.01 );in contrast,com-pared to H/R,IMD treatment ameliorated cell viability (79.1 5 ±1 .421 % vs 61 .22 ±1 .63%,P <0.05)and decreased LDH activities by 33.85% (P <0.01 ).②The proliferation of NRK-52E cells was significantly in-hibited by H/R treatment.In comparison to the con-trol,H/R treatment of NRK-52E cells increased the proportion of cells in the G0 /G1 phase but decreased the proportion of cells in the S and G2 /M phases. Moreover,the over-expression of IMD resulted in S and G2 /Mphase redistribution and the accumulation of G2 /M-phase cells.The real-time PCR and western blotting results indicated that the mRNA and protein expression levels of cyclin D1 ,CDK4 and p57 were increased in H/R-treated cells.IMD further stimulated this up-reg-ulated expression of cyclin D1 ,CDK4 and decreased the expression of p57 in NRK-52E cells.④Cyclin D1 had a predominantly nuclear localization in NRK-52Ecells,although cytoplasmic localization was also ob-served.Conclusion The study shows that the over-expression of IMD may promote renal cell proliferation and regeneration after renal tubular cell H/R injury via the up-regulation of cyclin D1 ,CDK and the down-reg-ulation of p57.
