Objective: To investigate the incidence of CMV infection(CMV-I) and CMV related diseases (CMV-D) after allogeneic hematopoietic stem cells transplantation in 70 consecutive allogeneic hematopoietic stem cells transplantation(allo-HSCT) patients and to search for the optimal prophylactic strategy.Methods: Blood samples were monitored using the CMV pp65 antigenemia assay.Of the 70 patients observed,30 patients with chronic myeloid leukemia［CML:CP(27),AP(2),BC(1)］,12 with acute myeloblastic leukemia(AML),10 with acute lymphoblastic leukemia(ALL)and other cases were NHL(3), AA(5), MDS(7), SCLC with pancytopenia (1),CLL(1), and MF (1). Sixty six patients received HLA - identical siblings transplantation and four received tranplants from their HLA- haploidentical donors. Seventy cases included allo-PBPCT (64 cases) , allo-BMT (4 cases) and allo-PB+BMT (2). Before transplantation, all patients and donors received CMV serological examination except 4 pairs of donors/recepients. All 66 patients (3 cases were CMV IgM positive) and 64/66 donors were CMV IgG positive. Results：After transplantation, 64/70 patients developed CMV viremia during monitoring period. Forty three of 70 patients developed CMV-D.Thirty five of them suffered from CMV-associated interstitial pneumonia(CMV-IP). The high peak levels of CMV antigenemia were associated with development of CMV disease　. Close correlation was found between acute graft vs host disease(GVHD) and CMV disease. The patients were followed up for 2 to 24 months. The patients who received preemptive therapy(group A)had significantly better outcome than CMV disease group(group B, P=0.0001). Conclusions: The results suggest that CMV antigenemia has high predictive value for subsequent CMV disease and CMV pp65 antigenemia -guided early therapy has particular advantage for avoiding morbidity and mortality caused by CMV disease.

This study was aimed to observe and analyze the effectiveness of platelet transfusion. The platelet count of 1786 patients before transfusion and on 20-24 hours after transfusion was determined by using Auto-Hematology Analyzer, the percent platelet recovery (PPR) was calculated, the platelet transfusion efficiency (PTE) was evaluated by PPR and hemorrhage presentation after platelet transfusion, and the PTE was statistically analyzed according to disease cause, transfusion frequency, platelet type and once transfusion amount. The results showed that the total PTE of 1786 patients was 52.5%. The comparison of PTE among groups of disease cause showed that PTE in leukemia and aplastic anemia (AA) was lowest, as compared with that of other diseases (P < 0.05), while PTE in operation group was highest. The comparison of PTE among groups of transfusion frequency revealed also statistical difference (P < 0.01), meanwhile PTE decreased with increasing of transfusion frequency. The comparison of PTE among groups of platelet type (platelet phoresis or platelet concentrate) showed statistical difference (P < 0.01). The comparison of PTE among groups of platelet concentrate of once transfusion amount showed no statistical difference (P > 0.05). It is concluded that the PTE closely relates with disease cause of patients, moreover transfusion frequency also associates with PTE, the more frequency of transfusion, the higher possibility of transfusion refractoriness. The PTE of platelet pheresis is obviously superior to that of platelet concentrate, while PTE of platelet concentrate not significantly relates with once adequate or not.

OBJECTIVETo study the incidence of human cytomegalovirus (CMV) and human herpesvirus 6 (HHV-6) infection in pediatric patients with hemopoietic stem cell transplantation (HSCT), and to explore the relationship between CMV and HHV-6 infection in pediatric patients with HSCT.

METHODSPediatric patients with HSCT in hemotology center of Beijing Children's Hospital were enrolled into this study from June 2007 to October 2009. Peripheral blood were collected every week after HSCT, and Fluorescent quantitation PCR and conventional PCR were used to detect CMV DNA load in serum and HHV-6 DNA in peripheral blood respectively. Genetic typing was conducted on HHV-6.

RESULTSFifty two pediatric patients with HSCT were enrolled into this study, and six hundreds and thirty six specimens were collected totally. CMV DNA was detected in fifty two specimens from twenty cases. The median time was 56 days after HSCT. The incidence of CMV infection was 38.5% (20/52) in all HSCT patients and 47.6% (20/42) in allogene HSCT patients. The incidence of late CMV infection was 22.2% (6/27) in allogene HSCT. Three patients died of CMV infection,and two died of CMV interstitial pneumonia. HHV-6 DNA was detected in thirty three specimens from fourteen cases. The median time was 23 days after HSCT. The incidence of HHV-6 infection was 26.9% (14/52)in all HSCT patients and 31% (13/42) in allogene HSCT patients. The genotype of HHV6 was all type B. HHV-6 DNA was positive in six of twenty cases with CMV infection. The incidence of co-infection was 30% (6/20).

CONCLUSIONSThere was a substantial incidence of CMV and HHV6 infection after HSCT. The relationship between earlier HHV6 infection and later CMV infection in pediatric patients with HSCT need further study.

OBJECTIVETo analyse the outcome of allogeneic peripheral blood stem cell transplantation (allo-PBSCT) for myelodysplastic syndromes (MDS).

METHODSTwenty-three patients with MDS received G-CSF mobilized HLA-identical sibling allo-PBSCT. The numbers of mononuclear cells (MNC) and CD34+ cells were 8. 25 (4.50 -22.36) x 10(8)/kg and 5.59 (1.57 - 12.22) x 10(6)/kg respectively. CsA and shorten course MTX were used for graft-versus-host disease (GVHD) prophylaxis and MMF was given on + 1 d - +28 d posttransplantation.

RESULTSAmong 23 patients, 22 achieved hematopoietic recovery. The median time of ANC > 1.0 x 10(9)/L and BPC > 50 x 10(9)/L were + 13 (+ 11 - +17) days and + 30 (+13 + 102) days respectively. Two patients died of transplant related complications and three died of disease relapse, while 18 patients survived. Kaplan-Meier analysis showed disease free survival and relapse rate were (77.8 +/- 8.7)% and (14.4 +/- 7.5)% respectively.

CONCLUSIONAllo-PBSCT is an effective treatment for MDS patients.

BACKGROUNDEmergence agitation is a common problem in pediatric anesthesia, especially after sevoflurane induction and maintenance anesthesia. The purpose of this study was to investigate the effect of sufentanil to reduce emergence agitation after sevoflurane anesthesia in children undergoing adenotonsillectomy compared with fentanyl.

METHODSOne hundred and five children, aged 3 - 11 years, were randomly allocated to receive normal saline (control group), sufentanil 0.2 µg/kg (S2) or fentanyl 2 µg/kg (F2) 1 minute after loss of the eyelash reflex. Anesthesia was induced and maintained with sevoflurane. Time to tracheal extubation, recovery time, Paediatric Anesthesia Emergence Delirium (PAED) scale, and emergence behavior were assessed.

RESULTSThe incidence of severe agitation was significantly lower in S2 and F2 groups vs. the control group, 4/32 and 15/34 vs. 24/34 respectively, (P = 0.002, 0.009, respectively). PAED scales were significantly different among three groups (P = 0.007), and lower in the S2 and F2 groups than in the control group (P = 0.007 and P = 0.025, respectively). And the incidence of severe agitation and the PAED scale score was significantly different between the S2 and F2 groups (P = 0.007, P = 0.019, respectively). Time to tracheal extubation and recovery time were similar in all three groups.

CONCLUSIONSAdministration of sufentanil at 0.2 µg/kg after induction of anesthesia reduced emergence agitation in children receiving sevoflurane anesthesia for adenotonsillectomy compared with fentanyl. This was without delaying the recovery time or causing significant hypotension.

OBJECTIVEOsteopetrosis is a rare genetic disorder and the malignant infantile osteopetrosis (MIOP) is the worst subtype of this disease. Seventy percent of patients die in six years of life without proper treatment. Hematopoietic stem cell transplantation (HSCT) offers the only chance of cure for MIOP.

METHODRetrospective analysis was performed on 8 patients with MIOP who underwent HSCT in Beijing Children's Hospital during the period from 2006 to 2011.

RESULTEight cases (4 male and 4 female, mean age at HSCT 13.5 months) were diagnosed as malignant infantile osteopetrosis. Conditioning regimen included fludarabine, busulfan and cyclophosphamide. All patients received cyclosporin for prophylaxis of graft vs. host disease (GvHD). A UMD recipient underwent CD34(+) cell selection. ATG/ALG, mycophenolate mofetil (MMF) and methotrexate (MTX) used for recipients with unrelated cord donor (2) and recipients with haplo-identical donors (5). Average time for neutrophil engraftment was 15.7 day (9 - 36), platelet engraftment was 43.3 day (10 - 68). The patients were followed up from 47 days to 5 years, 1 patient died of post-transplant complications. Seven cases presented better in clinical manifestation. Acute GvHD I°-II° was observed in 6 patients, III°-IV° in 2 patients. It was controlled by anti-GvHD therapy.

CONCLUSIONNon-allogenic stem cell transplantation treatment of infantile MIOP showed high survival rate and restoration of hematopoiesis in haploid transplant patients, therefore, non-allogenic HSCT may be an option to treat MIOP in children.

OBJECTIVETo evaluate the efficacy and safety of entecavir maleate (ETV) versus ETV in Chinese patients with hepatitis B e antigen(HBeAg)-positive chronic hepatitis B(CHB).

METHODSThe patient population of this previously published randomized, double-blind, double-dummy, controlled, multicenter study was expanded by patients in the 0.5 mg/day ETV maleate group (total n = 110) and patients in the 0.5 mg/day ETV group (total n = 108). At treatment weeks 12, 24 and 48, hepatitis B virus (HBV) DNA levels were measured by the Roche Cobas Ampliprep/Cobas Taqman PCR assay. Adverse events (AE) were recorded.

RESULTSAs in the original analysis, the two treatment groups showed similar characteristics at baseline. In addition, the results for the all therapeutic effects showed identical trends to the results obtained in the original analysis, including the statistically similar effects of ETV and ETV maleate treatment-induced decreases in mean HBV DNA level at weeks 12, 24, and 48 (ETV: by 4.28, 5.00, and 5.53 log10 IU/ml vs. ETV maleate: by 4.46, 4.99, and 5.51 log10 IU/ml, respectively; all vs. baseline P more than 0.05), achievement of undetectable levels of serum HBV DNA ( less than 20 IU/ml) at week 48 (ETV: 38.18% vs. ETV maleate: 35.19%; P more than 0.05), HBeAg loss rates at week 48 (ETV: 10.91% vs. ETV maleate: 12.96%; P more than 0.05), HBeAg seroconversion rates at week 48 (ETV: 7.77% vs. ETV maleate: 10.38%; P more than 0.05), normalization of alanine aminotransferase at week 48 (ETV: 75.47% vs. ETV maleate: 82.86%; P more than 0.05), and overall incidence of AE (ETV: 18.02% vs. ETV maleate: 17.43%; P more than 0.05).

CONCLUSIONPerforming analysis of the therapeutic efficacies of entecavir maleate versus entecavir with a larger study population confirmed our original findings of similar efficacy and safety profiles for these two drugs in patients with HBeAg-positive CHB.

BACKGROUNDAlthough thrombolytic therapy with rescue percutaneous coronary intervention (PCI) is a common treatment strategy for ST-segment elevation acute myocardial infarction (STEMI), scant data are available on its efficacy relative to primary PCI, and comparison was therefore the aim of this study.

METHODSThis multicenter, open-label, randomized, parallel trial was conducted in 12 hospitals on patients (age < or = 70 years) with STEMI who presented within 12 hours of symptom onset (mean interval > 3 hours). Patients were randomized to three groups: primary PCI group (n = 101); recombinant staphylokinase (r-Sak) group (n = 104); and recombinant tissue-type plasminogen activator (rt-PA) group (n = 106). For all patients allocated to the thrombolytic therapy arm, coronary angiography was performed at 90 minutes after drug therapy to confirm infarct-related artery (IRA) patency; rescue PCI was performed in cases with TIMI flow grade < or = 2. Bare-metal stent implantation was planned for all patients.

RESULTSAfter randomization it required an average of 113.4 minutes to start thrombolytic therapy (door-to-needle time) and 141.2 minutes to perform first balloon inflation in the IRA (door to balloon time). Rates of IRA patency (TIMI flow grade 2 or 3) and TIMI flow grade 3 were significantly lower in the thrombolysis group at 90 minutes after drug therapy than in the primary PCI group at the end of the procedure (70.5% vs. 98.0%, P < 0.0001, and 53.0% vs. 85.9%, P < 0.0001, respectively). Rescue PCI with stenting was performed in 117 patients (55.7%) in the thrombolytic therapy arm. Rates of patency and TIMI flow grade 3 were still significantly lower in the rescue PCI than in the primary PCI group (88.9% vs. 97.9%, P = 0.0222, and 68.4% vs. 85.0%, P = 0.0190, respectively). At 30 days post-therapy, mortality rate was significantly higher in the thrombolysis combined with rescue PCI group than in primary PCI group (7.1% vs. 0, P = 0.0034). Rates of death/MI and bleeding complications were significantly higher in the thrombolysis with rescue PCI group than in the primary PCI group (10.0% vs. 1.0%, P = 0.0380, and 28.10% vs. 8.91%, P = 0.0001, respectively).

CONCLUSIONSThrombolytic therapy with rescue PCI was associated with significantly lower rates of coronary patency and TIMI flow grade 3, but with significantly higher rates of mortality, death/MI and hemorrhagic complications at 30 days, as compared with primary PCI in this group of Chinese STEMI patients with late presentation and delayed treatments.
