There were 417 scientific articles on hematopoietic stem cell transplantation in the 54th annual meeting of American Society of Hematology (ASH),including 46 articles on lymphoma.This article reviews latest research on non-myeloablative allogeneic hematopoietic stem cell transplantation for the treatment non-Hodgkin' s lymphoma presented in the meeting.

T-lymphoblastic lymphoma (T-LBL) is a rare form of non-Hodgkin lymphoma (NHL),which is biologically similar to T-acute lymphoblastic leukemia(ALL),and occurs most frequently in childhood and adolescence.T-LBL progresses fast.The treatment of LBL with conventional chemotherapy regimens for NHL has shown relatively low rates of complete remission and of disease-free survival.Now,it is reasonable to treat patients with LBL with the current ALL-type protocols,and hematopoietic stem cell transplantation may yield a more favorable overall survival (OS) in T-LBL patients,especial in relapsed or refractory LBL patients.

Objective To study proliferation,secreted cytokines,immune phenotypes and cytotoxicity on Raji cells by cytokine induced killer (CIK) cells co-cultured with dendritic cells (DC).Methods The mononuclear cells from peripheral blood of healthy individuals were extracted,then cultured the cells under 5 ％ CO2 at 37 ℃ for 2 hours.DC were induced from suspended cells,and CIK cells were from adherent cells.After 9 days of nurturing,two types of cells were mixed.CIK cells were cultured alone as the control.The cytotoxic activity of CIK and DC-CIK cells were detected by MTT assay.The morphologies,proliferation,secreted cytokines,and immune phenotypes of the two cells in day 0,3,6,9,12,15 in culture were monitored.Results In day 12 in culture,comparing with CIK cells,DC-CIK cells significantly enhanced the proliferation rate [(42.44±2.68) fold vs (30.01±2.05) fold] (t =11.64,P ＜ 0.05) and had increased IL-2,IFN-γ,IL-12 and TNF-α secretion [(124.34±12.57) ng/L vs (56.32±6.58) ng/L,(496.60±95.32) ng/L vs (247.80± 69.45) ng/L,(84.92±6.07) ng/L vs (24.18±3.31) ng/L,(380.6±45.95) ng/L vs (196.61±24.19) ng/L] (t =15.16,P ＜ 0.05; t =6.67,P ＜ 0.05; t =27.78,P ＜ 0.05; t =11.20,P ＜ 0.05),and there were more CD3+ CD8+ cells and CD3+ CD56+ cells in the co-culture [(71.79±1.73) ％ vs (60.37±3.24) ％,(48.54±3.30) ％ vs (33.07±2.22) ％](t =9.83,P ＜ 0.05; t =12.30,P ＜ 0.05),and DC-CIK cells had a significandy increased cytotoxicity on Raji cells in vitro at the same ratio of effector cells to target cells.Conclusion CIK cells have higher proliferation rate and cytotoxicity against Raji cells when co-cultured with DC.

Bone marrow infiltration in lymphoma is crucial to the disease diagnosis,staging,treatment options and prognostic evaluation.Although bone marrow biopsy is the main detecting method,it has high false negative rate.At present,18F-fluorodeoxyglucose positron emission tomography-computed tomography (18 F-FDG PET-CT) technology which is integrating morphological characteristics with metabolic function provides a new way for the diagnosis,staging and prognostic evaluation of bone marrow infiltration in lymphoma due to its advantages of high sensitivity,high specificity and functional image.

Objective Using a short-term in vivo laboratory model of murine liver cancer induced with diethylnitrosamine (DEN),we inspected the impact of 5% C.Chrysantha leaves and 5% concentrations on induction of liver cancer with DEN.Methods Laboratory Winstar rats,all being male and SPF grade,were administered with the liver cancer initiator DEN(200?g/kg,ip,once only),then with murine food containing 0.015% 2-AAF (2-Acetaminoflueren) for 2 weeks,following an excision of the augmented parts as a selective promoting program that speeded up the proliferation of precancerous foci from the initiated hepatocytes.On the beginning of this experiment,5% C.Chrysantha leaves and 5% concentration-contained food were given to the trail rats; in contrast,normal food to the control.Rats were killed 3 days after feeding of 2-AAF-contained food.Targeting part of liver were collected for ?-glutamyltranspeptidase (?-GT) staining,and numbers and areas of?-GT positive foci per cm2 of the liver area were calculated using a software designed by us.Results Numbers and areas of?-GT positive foci of the trail are significantly less than those of the control.Conclusion 5% C.Chrysantha leaves and 5% concentrations inhibit the DEN induction to liver cancer.

Objective To investigate the clinical efficacy of Yang’s pricking-cupping bloodletting in treating cervical spondylotic radiculopathy and its effect on trapezius tension.Methods Seventy-eight patients with cervical spondylotic radiculopathy were randomly allocated to treatment and control groups, 39 cases each. The treatment group received pricking-cupping bloodletting and the control group, conventional acupuncture plus cupping. The nerve function was scored, the visual analogue scale (VAS) score was recorded and trapezius tension was measured in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results There were statistically significant pre-/post-treatment differences in the nerve function score, the VAS score and trapezius tension in the two groups (P<0.01). There were statistically significant post-treatment differences in the VAS score and trapezius tension between the treatment and control groups (P<0.05). The total efficacy rate was 94.9% in the treatment group and 89.7% in the control group. There was a statistically significant difference in theclinical therapeutic effect between the two groups (P>0.05).Conclusions Yang’s pricking-cupping bloodletting can effectively improve pain symptoms and trapezius tension in patients with cervical spondylotic radiculopathy.

Objective To investigate the effects of triptolide on proliferation,apoptosis and the changes of Ski,Smad3,Smad7 and collagen type I(ColI) in cultured rat mesangial cells induced by transforming growth factor (TGF)-β1.Methods Cultured HBZY-1 rat mesangial cells were divided into 5 groups:(1)normal control group; (2)TGF-β1 group (10 μg/L); (3)-(5)triptolide (0.4,2,10 μg/L)+TGF-β1 (10 μg/L) groups.The cell proliferation was detected by MTT.Apoptosis of mesangial cells was detected by TUNEL assay.The expressions of Ski,Smad3,Smad7 mRNA were examined by real-time quantitative PCR.The expressions of Ski,Smad3,Smad7 and ColI protein were detected by Western blotting.The localizations of Ski and Smad3 protein were detected by laser confocal fluorescence microscope.Results Compared with the normal control,TGF-β1 (10 μg/L) significantly stimulated mesangial cells proliferation,while decreased apoptosis.The mRNA and protein expressions of Ski,Smad7,Smad3 and ColI protein expression in TGF-β1 group were increased (P ＞0.05).In comparison with TGF-β1 group,triptolide could significantly inhibit TGF-β1-induced mesangial cells proliferation in dose-dependent manner,and promote the apoptosis of mesangial cells.In TGF-β1 group,mRNA and protein expresscons of Ski and Smad7 were increased (P＜0.05),Smad3 mRNA and protein were decreased (P ＞0.05),and ColI protein was decreased (P＜0.01).In comparison with TGF-β1 group,fluorescence intensity of Ski,Smad3 proteins was significantly increased in cytoplasm,while decreased in nucleus.Conclusions Triptolide can inhibit TGF-β1-induced mesangial cells proliferation through regulating the expressions of Ski,Smad7 mRNA and protein,inhibiting Ski.Smad7 translocation to the nucleus,and down-regulating Smad3 mRNA and protein expression.Triptolide can promote apoptosis of mesangial cells.

AIM:To observe the effect of Wnt/β-catenin signaling pathway on diabetic ulcer.METHODS:Diabetic animal model was established in the female Wistar rats by intraperitoneal injection of low-dose streptozotocin fol-lowing high-fat diet feeding.A circular wound was made on the dorsum of the rats in both control group and diabetic group. The condition of wound healing was recorded and the structures of the wound tissues were observed by HE staining in the 2 groups at 3, 7 and 14 d after wounding.The expression ofβ-catenin, GSK-3βand Rspo-3 at mRNA and protein levels in the wound tissues was detected by RT-PCR and ELISA.RESULTS:In diabetic group, the wound healing rate was lower (P<0.05), and the inflammatory cells, fibroblast cells and new capillaries in the wound tissues were fewer than those in control group.The expression of β-catenin and Rspo-3 at mRNA and protein levels in the wound tissues in control group was significantly higher than those in diabetic group, and the expression of GSK-3βwas exactly the opposite (P<0.05). CONCLUSION:The down-regulation of Wnt/β-catenin probably resultes from the decreased level of Rspo-3, which may be one of the reasons for delaying the diabetic ulcer healing.
