Objective To investigate the expression of HOXB4 gene in patients with myelodysplastic syn-dromes(MDS)and its clinical significance in disease progression.Methods mRNA expression of HOXB4 gene in bone marrow mononuclear cells was detected by real-time fluorescence quantitative PCR(RT-qPCR),and the difference in HOXB4 expression was compared between 49 patients with MDS(MDS group)and 35 patients without MDS(group C).The relationship of mRNA expression of HOXB4 with disease characteristics and clinical prognosis was explored in MDS patients.Results mRNA expression level of HOXB4 gene was higher in MDS group than that in group C(P<0.05).The patients were divided into a high-and a low-expression group according to the median expression level of HOXB4.Leukocyte count was lower in the high-expression group in the low-expression group at the time of initial diagnosis.The proportion of patients with subtypes of primitive cellular hyperplasia,poor prognostic staging and leukemic transformation was higher in the high-expression group than in the low-expression group.Conclusions mRNA expression level of HOXB4 gene has certain relation with AML transformation in MDS patients.

OBJECTIVETo investigate the efficacy of liposomal doxorubicin together with etoposide and high dose methylprednisolone (DEP) as a salvage therapy for adult refractory hemophagocytic lymphohistiocytosis (HLH).
METHODSTotal 41 patients with refractory HLH were enrolled in this study. The efficacy of treatment with DEP regimen after 2 and 4 weeks were evaluated according to the United States Midwest Cooperative HLH Group.
RESULTSOf 41 refractory HLH patients, 28 were males and 13 females. The median age was 31(18-62) years old. The overall response rate (ORR) was 78.1%(32/41), including 12 patients (29.3%) achieved complete remission (CR) and 20 (48.8%) achieved partial remission (PR). The underlying disease of HLH were identified in 33 patients, including 1 case of primary HLH (CR), 20 cases of lymphoma associated HLH and 12 cases of EBV associated HLH. There were still 8 cases with unknown underlying disease. The 9 patients who had no response to DEP died within 2 to 4 weeks after salvage therapy. Twenty of the 32 patients who achieved PR or CR survived to undergo subsequent chemotherapy, allogenic hematopoietic stem cell transplantation (allo-HSCT) or splenectomy.
CONCLUSIONThe single-arm study suggested that DEP regimen appeared to be an effective salvage protocol for adult patients with refractory HLH.

OBJECTIVETo analyze the clinical manifestations, laboratory data, therapy, and prognosis in patients with hemophagocytic lymphohistiocytosis (HLH).
METHODSA retrospective study was carried out in 192 adult patients with HLH between 2003 and 2013.
RESULTSOf the 192 cases, 70 cases were secondary to cancer and 64 cases secondary to infection. According to HLH-2004 criteria, the coincidence rate of indices were: fever (98.96%), high level of serum ferritin (94.27%), increased level of soluble interleukin- 2 receptor(sCD25) (94.79%), decreased or absent activity of NK cells (94.27%), cytopenias (80.73%), splenomegaly (80.21%), emophagocytosis in bone marrow, spleen or lymph nodes (74.48%), hypofibrinogenemia (50.52%), hypertriglyceridemia (37.50%). In addition, 94.27% of patients were presented with liver dysfunction, 96.35% with infections, and 75.52% with coagulopathy. Incidences of central nervous system symptoms and rash were 19.27% and 20.31%, respectively. Among cancer, infection and rheumatic group, there were statistically differences on white blood cells (WBC), platelet (PLT), sCD25, alanine aminotransferase, aspartate aminotransferase, total bilirubin and globulin(GLO) (P<0.05). The differences of WBC, PLT, albumin (ALB), GLO, brain natriuretic peptide, creatinine, urea nitrogen between survival group and death group had statistical significance.
CONCLUSIONThe secondary HLH occurs from various underlined diseases. Cancer, especially T- cell lymphoma, is the main cause, Secondly, it is EB virus infection. The diagnostic sensitive indicators are Persistent fever, higher level of serum ferritin, low or absent NK-cell activity, and increased sCD25 were the most valuable parameters for diagnosis. Cytopenias were not common in early phase of HLH secondary to rheumatic diseases. WBC, PLT, ALB, GLO could be used as the preliminary parameters for diagnosis. Cardiac insufficiency, renal insufficiency and coagulation dysfunction play important roles in prognosis.

OBJECTIVETo investigate the outcomes, survival status, and the prognostic factors of Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis (EBV-HLH) patients.
METHODSA retrospective study was carried out to analyze the clinical data of 61 EBV-HLH cases, from January 2008 to July 2014. Prognostic factors were analyzed through COX model (single factor and multiple factors).
RESULTSA total of 246 patients with HLH were diagnosed, among which 102 cases were with EBV infection (including 61 EBV-HLH, 36 lymphoma associated HLH, 5 primary HLH. Among the 61 cases, 40 were male and 21 were female, with a ration of 1.9:1. The median age was 28 years (range, 12-78). 1, 3, 6 and 12-month overall survival rates of 61 EBV-HLH were 65.6%, 47.5%, 32.4%, and 25.0%, respectively. The median follow-up time was 3 (0.5-28) months. 12 patients didn't use etoposide within 4 weeks after diagnosis, while HLH-94 protocol was used in 33 patients and HLH-2004 protocol was used in 16 patients. Response rates of theses three groups were 33.3%, 51.5%, and 43.8%, respectively (P=0.401). There was statistically difference between the group without etoposide and the HLH-94/ HLH-2004 group in the overall survival rate (P=0.033). Serum albumin level (P=0.033) and whether EBV could became negative (P=0.010) were independent predictors for EBV-HLH.
CONCLUSIONEBV-HLH patients have severe clinical feature and poor prognosis. Early application of immune chemotherapy based on etoposide can improve survival. Serum albumin level and whether EBV can become negative are independent prognostic factors for survival.
