Objective To investigate mRNA and protein expression of aproliferation-inducing ligand (APRIL) in peripheral blood mononuclear cell and plasma of patients with B cells non-Hodgkin lymphoma (B-NHL) pre- or post- chemotherapy and to explore the role of APRIL in the B-NHL. Methods The mRNA and protein expression of APRIL were detected by real-time fluorescence quantitative polymerase chain reaction (RFQ-PCR) and enzyme-linked immunosorbent assay(ELISA), respectively. According to the standard curves,the quantitative levels of target mRNA and protein were determined. Results The detection linear range of targeted mRNA by RFQ-PCR was 101-109 pg/ml, and the coefficient of variation values for both intra- and inter-experimental reproducibility ranged 1.69 %-5.99 % and 6.35 %-10.12 %, respectively. To detect expression of APRIL protein by ELISA, the correlation coefficient of standard curves reached 0.9922. Before or after chemical treatment, the expression levels of APRIL mRNA and protein in patients with B-NHL were significantly higher than those in normal control (P ＜0.01), while the expression levels in post-treatment patients with Ⅲ and Ⅳ stage were lower than those of pre-treatment patients with corresponding stage (P ＜0.05, respectively), but those of pre- and post-treatment patients with Ⅰ / Ⅱ stage were not different (P ＞0.05).Conclusion The expression level of APRIL mRNA is similar to that of APRIL protein. APRIL may be involved in pathogenesis and development of B-NHL. Moreover, APRIL may be related to the burden of B-NHL and it may be considered as a targeted molecule for B-NHL.

OBJECTIVE To investigate the protective effect of collagen peptides from walleye pollock skin(CPWPS)in the hydrogen peroxide(H2O2)-induced oxidative stress damage model of the human keratinocyte cell line (HaCaT). METHODS HaCaT cells were pretreated with CPWPS 50,100 and 200 mg · L-1 for 12 h. Then H2O2 was added to the final concentration of 300μmol · L-1. After 12 h,the activity of catalase(CAT),glutathion peroxidase(GSH-Px),total superoxide dismutase(T-SOD)and total antioxidant capacity (T- AOC) were detected by enzymes and biochemical method. The expression of aquaporin3 (AQP3) in HaCaT cells was measured by Western blotting. RESULTS Compared with control group,CPWPS group did not exhibit significant cytotoxicity at a concentration up to 300 mg·L-1. The viability of cells treated with H2O2 300μmol·L-1 for 12 h decreased to 54.0%(P<0.01). The viability of cells pretreated with CPWPS 50,100 and 200 mg · L-1 for 12 h increased to 69.4%,79.4%and 89.1%(P<0.05,P<0.01),respectively. Compared with the model group,the activity of CAT,GSH-Px,T-SOD and T-AOC in HaCaT cells pretreated with CPWPS 50,100 and 200 mg·L-1 for 12 h increased. Compared with model group,the activity of CAT,GSH-Px,T-SOD and T-AOC of CPWPS 200 mg · L-1 pretreatment group increased by 56.90%,48.68%,48.24% and 71.43%(P<0.01),respectively. Western blotting revealed that the expression of AQP3 in H2O2 model group was in?creased relative to that in control group,while the expression of AQP3 in CPWPS pretreatment groups was decreased. The expression of AQP3 in CPWPS 200 mg · L-1 pretreatment group decreased to 67.1%(P<0.01) compared to the H2O2 model group. CONCLUSION CPWPS can protect HaCaT cells against H2O2- induced oxidative stress damage. The cytoprotective effects are associated with enhanced antioxidant capacity and decreased expression of AQP3.

A cold-adapted (ca), temperature sensitive (ts), live attenuated influenza B virus strain B/Ann Arbor/1/66 was chosen for influenza virus rescue research, in which six internal gene segments, PB1, PB2, PA, NP, M, NS, were fully synthesized and nine amino acid substitutions were artificially alter by human intervention. The resultant B/Ann Arbor/1/66 plasmids were named as pAB121-PB1, pAB122-PB2, pAB123-PA, pAB124-HA, pAB125-NP, pAB126-NA, pAB127-M and pAB128-NS, respectively. A recombinant influenza A virus was previously generated entirely from cloned cDNA. An infectious recombinant influenza B virus was generated here, and designated as rMDV-B, by plasmid-based reverse genetics. The rMDV-B virus contained HA and NA genes from an epidemic influenza B vires strain B/Malaysia/2506/2004 in the background of internal genes derived from influenza B virus strain B/Ann Arbor/1/66. HA titer of rMDV-B in MDCK cells and embryonated chicken eggs ranged from 1 : 64 to 1 : 512. The results may allow an effective live influenza B vaccine to be produced from a single master strain, providing a model for the design of future live human influenza vaccines.

Six gene segments, PB1, PB2,PA, NP, M and NS, were fully synthesized which derived from the master donor virus(MDV), cold-adapted(ca),temperature sensitive(ts), live attenuated influenza virus strain A/Ann Arbor/6/60(MDV-A). Meanwhile, five amino acid substitutions (PB1-391E, 581G, 661T, PB2-265S, NP-34G) were artificially altered by human intervention. HA and NA fragments derived from the 2006～2007 circulating strain A/New Caledonia/20/99 (H1N1). Eight fragments were ligated with modified pAD3000 for rescue plasmid construction. Eight transcription/expression plasmids were named as pMDV-A-PB2, pMDV-A-PB1, pMDV-A-PA, pMDV-A-NP, pMDV-A-M, pMDV-A-NS, pMDV-A-HA, pMDV-A-NA, respectively. The COS-1 cells were co-transfected with eight plasmids representing 6 internal viral backbone of the strain A/AA/6/60 and two plasmids containing the cDNA of the HA and NA segments of the strain A/New Caledonia/20/99 (H1N1), the results showed that cold-adapted, attenuated reassortant influenza A virus was rescued successfully. Titers of a reassorted influenza A virus in embryonated chicken eggs ranged from 1∶29 to 1∶210. The rescue system of six internal genes used as backbone opens the way for further research on gene function and neotype vaccine candidate of cold-adapted, live attenuated human influenza virus.

Objective: To analyze the clinical characteristics and prognosis of 34 cases of acute myeloid leukemia (AML) with FLT3 internal tandem duplication (FLT3-ITD) and MLL gene rearrangement. Methods: The clinical data of 34 AML patients with FLT3-ITD and MLL gene rearrangement was compared and analyzed for the therapeutic efficacy, prognostic factors when treated with chemotherapy, chemotherapy combined with targeted therapy or allogenic hematopoietic stem cell transplantation (allo-HSCT). Results: Of the thirty-four cases with median age 41 (4-71) years old, 63.6% presented with white blood cells (WBC) greater than 30×10⁹/L, 39.4% greater than 50 × 10⁹/L respectively on admission. M₅ (35.3%) made up the highest proportion. The cytogenetic abnormality reached 61.8%, of which the complex cytogenetic abnormality accounted for 11.8%. Eleven patients (32.35%) had both FLT3-ITD and MLL gene abnormalities. In addition to FLT3 and MLL abnormalities, 23 patients (67.6%) had one or more other gene abnormalities (multiple gene abnormalities). Of the 34 cases, 29.4% patients went into complete remission (CR) after two courses of chemotherapy. 20.6% (7 patients) went into CR after 3 or more courses of chemotherapy. The rate of early relapse in the CR group was 52.9%. Patients with WBC>50×10⁹/L or multiple gene abnormalities had a lower remission rate (7.7%, 5.4%) after two courses of chemotherapy. CR rate for the patients with more than three gene abnormalities was 0. The total 2-year overall survival (OS) in the 34 patients was 28.8% (95% CI 13.5%-46.0%) and the disease-free survival (DFS) was 27.1% (95% CI 12.5%-44.0%). Of the 18 patients treated with chemotherapy alone or chemotherapy combined with targeted therapy, 17 cases died within 2 years and 1 lost follow-up after giving up treatment. For the 16 patients received allo-HSCT, the 3-year OS was 43.4% (95% CI 13.7%-70.4%) and DFS 42.7% (95% CI 13.4%-69.7%). Conclusion AML patients with FLT3-ITD and MLL gene rearrangement often presented with M₅, accompanied by hyperleukocytosis, cytogenetic or multiple gene abnormalities. Those patients were observed to have low response rate and high early relapse when treated with chemotherapy without allo-HSCT. Patients had multiple gene abnormalities may be an important poor prognostic factor. Allo-HSCT is an effective treatment which could significantly improve the prognosis and survival of AML patients with FLT3-ITD and MLL gene abnormalities.

OBJECTIVETo evaluate the efficacy of HLA- haploidentical donor hematopoietic transplantation (Haplo- HSCT)for severe aplastic anemia (SAA)by compared with the same period of unrelated donor transplantation (UD- HSCT).

METHODSOf a cohort of 50 SAA patients between September 2012 and July 2014, 26 patients underwent UD- HSCT and 24 patients Haplo- HSCT.

RESULTSOS rate was 91.3% with a median follow-up of 9 (2-26)months. According to transplant type, there was no significant difference between UD- and Haplo-HSCT (96.1%vs 86.0%,P=0.30). 3 of 50 (6%)patients had primary engraft failure. Haplo- HSCT developed higher significantly incidence of Ⅱ- Ⅳ aGVHD (37.5%vs 3.83%,P=0.003)and cGVHD (37.5%vs 15.3%,P=0.030)than UD-HSCT. Haplo-HSCT also had significantly higher incidences of CMV viremia (78.2%vs 46.1%,P=0.005)and EBV viremia (43.1%vs 16.0%,P=0.040), respectively than UD-HSCT. But the incidences of hemorrhagic cystitis were similar between two transplant types (39.1%vs 23.0%,P=0.120).

CONCLUSIONThis study showed favorable outcome of Haplo-HSCT for SAA, which was comparable with UD-HSCT.
