Full-length NS5A gene of the hepatitis C virus was amplified by PCR using plasmid pBAC25 containing HCV nonstructural gene as template. The amplified fragment (about 1.34 kb) was cloned into plasmid pQE32, and the recombinant plasmid pQENS5A was expressed in JM109 strain. The NS5A protein was purified by NiSO4 metal chelating resin, and characterized by Western-blot. Its antigenecity was determined by ELISA. The positive detection rate of anti-NS5A was 75% (69/92) in ninety-two clinic sera. The positive rate of anti-NS5A was 82.5% (33/40) in fourty positive standand sera, and the negative rate of anti-NS5A was 100% (40/40) in fourty negative standand sera. The results showed that the Full-length NS5A proteinn had the higher sensitivity and specificity in the detection of HCV antibody in sera, we suggested that NS5A protein was a useful antigen for blood screening.

OBJECTIVETo explore the inhibition effect of N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP) on myofibroblast differentiation of MRC-5 human fetal lung fibroblasts induced by angiotensin (Ang) II.
METHODSThe study was divided into 2 step: (1) MRC-5 human fetal lung fibroblasts was induced for 48 h at different dose of Ang II and at different time point by 100 nmol/L Ang II. Then the expression of collagen type I and α-smooth muscle actin (α-SMA) were mesaured by western blot. (2) MRC-5 human fetal lung fibroblasts were divided into 4 group: (1) control, (2) Ang II, (3) Ang II+Ac-SDKP, (4) Ang II+8-Me-cAMP (a specific activator of Epac). The α-SMA expression was observed by immnocytochemical stain. The protein expression of collagen type I, α-SMA, serum response factor (SRF), myocardin-related transcription factor (MRTF)-A, exchange protein directly activated by cAMP (Epac) 1, 2 were measured by Westen blot.
RESULTSMyofibroblast differentiation could be induced by Ang II from MRC-5 cells with a dose- and time-dependent manner. The up-regulation of SRF and MRTF-A were observed in MRC-5 cells induced by Ang II and accompanied with collagen I and α-SMA increased. Pre-treatment with 8-Me-cAMP or Ac-SDKP could attenuated all this changes induced by Ang II, and promoted the expression of Epac1.
CONCLUSIONAc-SDKP can inhibit the myofibroblast differentiation of MRC-5 cells induced by Ang II via Epac1 activating.

The purpose of this study was to investigate the efficacy of non-myeloablative allogeneic stem cell transplantation (allo-NST) and its related technologies in hematological malignancies. 26 patients with hematological malignancies (acute leukemia 10, chronic myeloid leukemia 14, multiple myeloma 2) received allo-NST following conditioning regimens with fludarabine/cyclophosphamide/ATG in 14 cases or busulfan or melphalan/cyclophosphamide/ATG in 12 cases prior to infusion of 2 or 3 collections of G-CSF (600 microg/d) or G-CSF (300 microg/d) plus GM-CSF (300 microg/d) mobilized blood stem cell on the fifth day. A combination of cyclosporine A (CsA) and methotrexate (MTX) was administered for GVHD prophylaxis. Patients were eligible for donor lymphocyte infusion (DLI) (or donor stem cell infusion (DSI)) given in graded increments according to the chimeric formation and clinical feature. Generally, the dose of the first infusion was 1 x 10(7)/kg in 4th week post-transplantation. The engraftment analyses included the detection of microsatellite short tandem repeats (STRs), bcr/abl fusion gene, Philadelphia chromosome, HLA-locus analysis, sex chromosome and ABO blood type or blood subtype. The results showed that out of 26 patients, 22 (84.62%) were engrafted, 18/22 were full donor chimerism (FDC) up to now. Acute GVHD occurred in 3/26 (11.54%), while chronic GVHD was diagnosed in 6 out of 26 (23.07%) patients. The incidence and degree of infection and hemorrhage were low and slight. It is concluded that NST is a safe and effective therapy for hematological malignancies, whereas related technologies such as adaptation selected, conditioning regimen and transplantation immunotherapy should be studied further.

OBJECTIVETo explore the clinical characteristics of nosocomial septicemia in the early stage after hematopoietic stem cell transplantation (HSCT) in children with major β-thalassemia.
METHODSThe clinical data were retrospectively analyzed of 55 consecutive children with major β-thalassemia who developed septicemia early after HSCT between January, 2011 and June, 2016.
RESULTSAmong the total of 416 consecutive children with major β-thalassemia undergoing allogeneic HSCT, the incidence of nosocomial infection early after transplantation was 77.16% (321/416), and 55 (17.13%) children showed positive findings in blood culture test. The infections occurred most commonly in the oral cavity (65.5%), followed by the respiratory tract, intestinal tract and skin. Gram-negative bacteria, including Escherichia coli (27.3%), Klebsiella pneumoniae (21.8%) and Pseudomonas aeruginosa (9.1%), were the most common causes of infections. Fungal (Candida tropicalis) infection caused septicemia in 1 case. Of all the pathogens, extended-spectrum β-lactamase (ESBL)-producing bacteria were found in 6 cases, methicillin-resistant Staphylococcus aureus (MRSA) in 2 cases, and multidrug-resistant (MDR) bacteria in 2 cases.
CONCLUSIONGram-negative bacteria are the major pathogens causing septicemia in children early after HSCT for major β-thalassemia, and the bacteria show a high level of drug resistance. Adequate preventive use of antibiotics and care of the oral cavity, the respiratory tract, and the perianal region following the transplantation are important measures to control nosoconial infection in these children.
7.Research Advances on Pathogenesis of Myelodysplastic Syndrome.
Journal of Experimental Hematology 2015;23(6):1800-1807
Myelodysplastic syndrome (MDS) is a clonal marrow stem cell disorder, characterized by ineffective haemopoiesis leading to blood cytopenias. As a disease of grey zone, along with the development of research, the exploration on its pathogenesis have been shifted from molecular genetics and the feature of immunophenotype to the epigenetic and micro environment. But at present, the pathogenesis of MDS is still not clear, the research of the molecular genetics and immunophenotype can not meet the needs of experimental and clinical application any longer. The hematopoietic stem cells, cytokines, epigenetic studies, however, have made a lot of achievements. Targeted medicine such as azacitidine and decitabine had promising response in treating MDS patients. In this article the abnormality of stromal cells, cytokines and epigenetic changes in hematopoietic microenvironment of MDS are reviewed in order to optimize the monitoring MDS progress and guide its clinical medication strategy.

OBJECTIVETo determine whether U50488H, a selective agonist of kappa-opioid receptor, could induce biphasic (early and late) cardioprotection against myocardial ischemia/reperfusion injury and to explore the underlying mechanisms.
METHODSIsolated perfused rat hearts were subjected to 30 min of ischemia followed by 120 min reperfusion and the cardiac function was evaluated.
RESULTLeft ventricular end-diastolic pressure (LVEDP), left ventricular developed pressure (LVDP) and maximal velocity of contraction and relaxation (+/-dP/dtmax) were improved when U50488H was administered 1 or 24 h before ischemia (P<0.05). Myocardial infarct size, activities of creatine kinase (CK) and lactate dehydrogenase (LDH) in the coronary effluent were lower in the U50488H pretreatment group than those in the control group. Administration of a selective cyclooxygenase-2 (COX-2) inhibitor, celecoxib abolished the late phase of cardioprotection produced by administration of U50488H 24 h before ischemia. Activities of CK and LDH in the coronary effluent were higher in U50488H and celecoxib co-pretreatment group than those in U50488H group. However, administration of celecoxib did not block the early phase of cardioprotection by 1 h treatment of U50488H before ischemia.
CONCLUSIONThe late (but not the early) phase of cardioprotection induced by kappa-opioid receptor agonist might be mediated by COX-2.

OBJECTIVETo investigate the role of Snitrosylation of protein disulphide isomerasec in methamphetamine (METH)-induced expression of alpha synuclein (αSN) in mouse hippocampus and striatum neurons.
METHODSForty C57BL/6 mice were randomized equally into saline control group, METH group, L-NNA (a NOS inhibitor) group and L-NNA plus METH group. All the agents were injected intraperitoneally at an interval of 12 h, and a total of 8 injections were administered; in L-NNA plus METH group, METH was injected 30 min after LNNA in each treatment. Western Blotting was used to detect the expression of nitric oxide synthase (NOS), αSN, PDI and Snitrosylation of protein disulphide isomerase (PDI-SNO) in the hippocampus and striatum of the mice, and nitric oxide (NO) levels were determined using a NO assay kit.
RESULTSIn METH group, the levels of NOS, PDISNO, αSN and NO all increased significantly compared with those in the control group (P<0.05). Combined treatment with L-NNA and METH, compared with METH alone, resulted in significantly lowered expression of NOS, NO, PDI-SNO and αSN in the hippocampus and striatum of the mice (all P<0.05). No significant differences were found in NOS, NO, PDI-SNO or αSN expressions among METH+L-NNA, L-NNA and control groups (P>0.05).
CONCLUSIONMETH induces the activation of NOS and increases NO level to cause the occurrence of PDI-SNO, leading subsequently to increased expression of αSN in mouse striatum and hippocampus. L-NNA, the inhibitor of NOS, can partly relieve nervous system toxicity induced by METH.

OBJECTIVETo investigate the effect of the non-PLC-dependent protein kinase C (PKC) pathway of parathyroid hormone (PTH) on the apoptosis and proliferation of osteoblast MC-3T3E1 cells.
METHODSMC-3T3E1 cells were seeded in 96-well plates at the density of 1.5×10(4) cells/mL and incubated for 3 day. The cells were then exposed to 100 nmol/L of [Gly(1), Arg(19)]hPTH(1-28), 100 nmol/L of [Gly(1), Arg(19)]hPTH(1-34), 100 nmol/L of [Gly(1), Arg(19)]hPTH(1-34)+1 µmol/L Go6983, 1 µmol/L Go6983, or deionized water (control) for 1, 24 or 48 h. After the treatments, cell counting kit-8 (CCK-8) and Caspase-Glo® 3/7 Assay (Caspase-3) were used to examine the proliferation and apoptosis of MC3T3-E1 cells.
RESULTSCCK-8 results showed that hPTH(1-34) increased the number of MC3T3-E1 cells compared with hPTH(1-34)+Go6983 at 1 h and 24 h, but this difference was not statistically different. At 48 h, treatment with hPTH(1-34), as compared with hPTH(1-28), significantly increased the number of MC3T3-E1 cells (P<0.05), and this effect was blocked by the PKC inhibitor Go6983 (P<0.05). hPTH(1-34) did not result in significant inhibition of MC3T3-E1 cell apoptosis at 1 h and 24 h as compared with hPTH(1-34)+Go6983, but significantly inhibited the cell apoptosis as compared with hPTH(1-28) (P<0.05); this inhibitory effect was blocked by Go6983 (P<0.05).
CONCLUSIONs A relatively long time (for 48 h) of exposure to PTH can inhibit apoptosis and promote the proliferation of MC3T3-E1cells through a non-PLC-dependent PKC pathway.
