AIM:
To isolate and characterize the anti-complementary polysaccharide from the root of Bupleurum chinense.
METHODS:
Bioactivity-guided fractionation and purification was used to obtain the anti-complementary polysaccharide from the hot-water extract of the root of Bupleurum chinense. The polysaccharide was characterized by various chemical and spectral analyses. The anti-complementary activities were evaluated by hemolytic assay in vitro. The action targets were identified in the system with individual complement-depleted sera.
RESULTS:
A homogeneous polysaccharide BC-PS2 was isolated as an anti-complementary agent. It was identified as a branched polysaccharide with an average molecular weight about 2 000 KDa, composed of Glc, Ara, Gal, and Man in the ratio 3.5 : 2.4 : 2.0 : 1.0, respectively, along with a trace of Rha and Xyl, and only 1.11% of protein. The main linkages of the residues of BC-PS2 include terminal, 1, 6-linked, 1, 3-linked and 1, 3, 6-linked Glcp, terminal and 1, 5-linked Araf, terminal, 1, 4-linked, 1, 6-linked and 1, 4, 6-linked Galp, terminal, and, 1, 4-linked and 1, 4, 6-linked Manp. The bioassay experiments revealed that BC-PS2 inhibited complement activation on both the classical and alternative pathways, with CH50 and AP50 of (0.222 ± 0.013) and (0.356 ± 0.032) mg·mL(-1), respectively. Preliminary mechanism studies indicated that BC-PS2 interacted with C1q, C2, and C9 components.
CONCLUSION
The results demonstrated that BC-PS2 is an anti-complementary polysaccharide, and should be important constituent of the root of Bupleurum chinense for its application in the treatment of diseases associated with the excessive activation of complement system.

OBJECTIVETo evaluate the alterations in coagulation in patients during conditioning with modified busulfan plus cyclophosphamide (BU/CY) +/- antithymocyte globulin (ATG) regimen before allogeneic hematopoietic stem cell transplantation (allo-HSCT), and to assess the effect of ATG on coagulation system.
METHODSThirty-five patients with various hematological malignancies undergoing allo-HSCT were assessed. Of them, 19 patients with HLA-matched sibling donors (group A) were conditioned with modified BU/CY regimen, 16 with HLA-mismatched family members or HLA-matched unrelated donors (group B) were conditioned with modified BU/CY + ATG regimen. Blood samples were collected before the beginning of conditioning till d + 1 after allo-HSCT. The following parameters were measured: prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fg), antithrombin (AT), D-Dimer, fibrin degradation product (FDP), platelet (BPC), liver enzymes and bilirubin. FVIII: C, FIX: C, FXI: C and FXII: C in prolonged APTT blood samples were also determined. Clinical hemorrhagic symptoms were monitored.
RESULTSDuring conditioning, temporary lengthening of APTT, persistent rising in Fg and declining of BPC were observed in the two groups. Alterations of Fg and BPC were more significant in group B than in group A. Transient D-Dimer increase occurred only in group B on administration of ATG. Among intrinsic pathway coagulation factors, FXII: C and FXI: C were commonly decreased while APTT prolonged. No difference between the two groups was found with regard to PT, FDP, AT and liver parameters which remained in normal ranges. Most of patients in the two groups did not have overt bleeding manifestations.
CONCLUSIONSModified BU/CY +/- ATG conditioning regimen can induce subclinical alterations in coagulation. The regimen containing ATG has more significant effect on coagulation parameters.

OBJECTIVETo study the effect of growth factor-primed donor hematopoietic stem cells infusion (GPBSCI) as an early adoptive immunotherapy.
METHODSTwelve patients with high-risk leukemia received prophylactic GPBSCI after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Out of the 12 patients, two were Ph(+) ALL in CR(1), one ALL in CR(2), one refractory ALL, three AML (one in relapse, one refractory disease, one in CR(3)), four CML in advanced stage and one myelodysplastic syndrome-refractory anemia with excess blast (MDS-RAEB).
RESULTSSixteen infusions were performed in the 12 patients, including 5 infusions were performed within +90 days post-SCT. The median mononuclear cells (MNC) and CD3(+) cells infused for GPBSCI before +90 d were 1.00 (0.95 - 1.24) x 10(8)/kg and 0.53 (0.39 - 0.63) x 10(8)/kg, and after +90 d were 2.27 (1.00 - 4.30) x 10(8)/kg and 1.15 (0.55 - 2.10) x 10(8)/kg, respectively. Four patients developed grade I - II acute GVHD, and one grade III acute GVHD. Seven patients developed chronic GVHD, of which four cases were extensive. Two patients had no transfusion related GVHD. No transfusion related pancytopenia was observed. Ten patients survived disease-freely at 563 (415 - 728) days of follow-up. Two patients died of leukemia relapse after GPBSCI.
CONCLUSIONAllo-HSCT with prophylactic GPBSCI could maximize graft-versus-leukemia effect with few fatal complications and might be a potentially curative strategy for hematological malignancy patients with high risk of relapse.

OBJECTIVETo study the expression of plasma miRNA-497 in children with sepsis-induced myocardial injury and its clinical significance.
METHODSA total of 148 children with sepsis were enrolled. According to the presence or absence of myocardial injury, these children were divided into myocardial injury group (n=58) and non-myocardial injury group (n=90). The two groups were compared in terms of the changes in plasma levels of miRNA-497, cardiac troponin I (cTnI), creatine kinase-MB (CK-MB), N-terminal pro-brain natriuretic peptide (NT-proBNP), procalcitonin (PCT), and C-reactive protein (CRP) and left ventricular ejection fraction (LVEF). The receiver operating characteristic (ROC) curve was plotted to evaluate the value of plasma miRNA-497, cTnI, and CK-MB in the diagnosis of myocardial injury. A Pearson correlation analysis was used to determine the correlation of miRNA-497 with cTnI, CK-MB, NT-proBNP, PCT, CRP, and LVEF.
RESULTSCompared with the non-myocardial injury group, the myocardial injury group had significantly higher plasma levels of miRNA-497, cTnI, CK-MB, NT-proBNP, PCT, and CRP (P<0.05). Plasma miRNA-497, cTnI, and CK-MB when measured alone or in combination had an area under the ROC curve of 0.918, 0.931, 0.775, and 0.940 respectively. At the optimal cut-off value of 2.05, miRNA-497 had a sensitivity of 90.4% and a specificity of 91.2%. The correlation analysis showed that there was a good correlation between plasma miRNA-497 and cTnI in children with myocardial injury (r=0.728, P<0.01).
CONCLUSIONSPlasma miRNA-497 has a similar value as cTnI in the diagnosis of sepsis-induced myocardial injury in children and may be used as a potential marker for early diagnosis of myocardial injury.
