Objective To improve the diagnosis efficiency of patients with angioimmunoblastic T-cell lymphoma (AILT)by analyzing the clinical characteristics and curative effect of AILT. Methods Retrospective studies were used on clinicopathological features,immunophenotypes,treatment and survival of 20 angioimmunoblastic T-cell lymphoma patients,who were collected between January 2005 and January 2010 of Beijing Military General Hospital. Results In the 20 patients receiving chemotherapy,the median age was 55.9 years old.All of the 20 had lymph nodes and 11 of whom were accompanied with B group of symptoms,which were confirmed by lymph node biopsy and T cell antigen CD3, CD45Ro positive expression in all the patients. ALL of the patients received the CHOP regimen and combining with other treatment such as DICE,ESHAP, Hyper-CVAD or autologous hematopoietic stem cell transplantation. A follow-up by 5 to 69 months showed that median survival was 20.2 (5-69) months and 1,2,and 3-year disease free survival (DFS) were 67 ％,33 ％,and 11％ respectively.8 patients of the group (40 ％) with a sustained remission (CCS) respectively survived 63,47,27,24,24,12,5,1 months so far.Conclusion Most patients were older with many complications during chemotherapy, which resulted in easy relapse, and even the symptoms were alleviated at the early stage of the chemotherapy. IPI prognostic index is more important with long-term survival in AITL.Therefore further studies are required to improve the outcome.

OBJECTIVETo study the effect of ozonized saline on the activation of the Keap1-Nrf2-ARE signaling pathway in rat liver cells.

METHODSTwenty male Sprague-Dawley rats were randomly divided into ozonized saline (OS) group, model group, ozonized saline control (OSC) group and normal control (NC) group. The rats in OS group and model group were intravenously administered with OS or oxygen saline (5 ml/kg) respectively, once a day for 15 days, and then intraperitoneally injected with CCl4 dissolved in oliver oil. The rats in OSC group were pretreated with OS for 15 days. The rats in NC group were fed normally for 15 days. On the 16th day, the rats in OSC group and NC group were intraperitoneally injected with oliver oil (2 ml/kg) without CCl4. After 24 hours of CCl4 or olive oil intraperitoneal injection, the serum levels of alanine transaminase (ALT) and aspertate aminotransferase (AST) were measured. The liver tissues were also collected for detection of total anti-oxygen capability (TAOC), glutathione (GSH), catalase (CAT), Glutathione peroxidase (GPx). Western Blot was used to detect Nrf2 and immunofluorescence staining assay to display intracelluar distribution of Nrf2.

RESULTSCompared with the rats in model group,the serum ALT and AST levels of rats in OS group were significantly lower (P < 0.01) ,which were (1240.4 ± 188.2) U/L and (1245.4 ± 176.9) U/L vs (539.8 ± 175.3) U/L and (546.0 ± 130.2) U/L, and the TAOC, CAT, GPx and GSH activity of rats in OS group were significantly higher, which were (0.72 ± 0.24) U/mg, (1.05 ± 0.21) mg/g, (676.9 ± 115.1) U/mg and (45.2 ± 14.3) U/mg vs (1.37 ± 0.19) U/mg, (2.23 ± 0.55) mg/g, (1024.6 ± 162.9) U/mg and (68.2 ± 9.9) U/mg, respectively. In contrast with NC group, pretreatment of OS in OSC group elevated TAOC, CAT, GPx and GSH activity (P < 0.01 or P < 0.05). Ozonized saline can strengthen the Nrf2 expression in liver cells.

CONCLUSIONPreconditioning injection of ozonized saline can reduce rat's liver injury induced by CCl4. The ozonized saline, as a novel Nrf2 activator, can reduce the oxidative damage of radical oxygen species (ROS) and the deleterious substance by activating the Keap1-Nrf2-ARE signaling pathway and its downstream genes expression.

Objective of this study was to evaluate the efficacy and safety of haploidentical or unrelated donor hematopoietic stem cell transplantation (HSCT) for patients with severe aplastic anemia (SAA). Twenty patients with SAA received allogeneic HSCT from haploidentical or unrelated donors (14 from haploidentical donors and 6 from unrelated donors) from November 2005 to May 2011. Conditioning regimen consisted of fludarabine (FLU), cyclophosphamide (Cy) and anti-thymocyte immunoglobulin (ATG). The patients were administrated with G-CSF-primed bone marrow and mobilized peripheral blood as grafts from haploidentical donor or only mobilized peripheral blood from the unrelated donor. The results showed that the median time of neutrophil and platelet engraftment were 14 (11 - 20) d and 17 (13 - 31) d respectively. All patients who achieved engraftment had complete hematologic recovery with complete donor chimerism, except for two patients who developed graft failure in 2 months after transplantation. Four cases developed acute grade IIGVHD. The chronic GVHD occurred in 7 of the 16 evaluable cases (6 limited, 1 extensive). 14 patients got disease-free survival with follow-up to January 2012. The disease-free survival rate was 68.9%. It is concluded that the haploidentical or unrelated donor hematopoietic stem cell transplantation may become a viable therapeutic option for severe aplastic anemia patients who lack suitable human leukocyte antigen-matched donors and fail immunosuppressive therapy.

Objective To evaluate the anti-angiogenic effect of eukaryotic vector containing human VEGF 165 and truncated pseudomonas exotoxin A (PE38) fusion gene on malignant glioma in nude mice, and explore a novel anti-angiogenic therapy for cancer. Methods The models were established through hypodermic injection of human U251 glioma cells into the nude mice and randomly divided into untreated group, PBS group, pIRES2-EGFP group and pIRES2-VEGF165-PE38-EGFP group on the 9th day. H&E staining was performed to observe the morphological changes of the glioma tissues; SP immunohistochemistry was employed to detect the expression of GFAP, CD31 andPE; quantitative pathologic image analysis system was used to investigate the microvessel density (MVD) in the tumor tissues. Results At day 16, the pIRES2-VEGF165PE38-EGFP group showed significantly lower tumor volume of mice and significantly decreased MVD than the other three groups (P<0.05). Positive expression of PE was shown in the pIRES2-VEGF165PE38-EGFP group, but negative in the other three groups. Conclusion The expression products of VEGFJ65-PE38 fusion gene can obviously inhibit the growth and angiogenesis of U2S1 cells in nude mouse flank tumor models, suggesting that it may be a novel therapeutic approach for anti-angiogenic therapy of cancer.

Using ultra high performance liquid chromatography (UHPLC) coupled with mass spectrum (MS) technology, a method has been established for separation and analysis of alkaloid isomers. Alkaloids in Ephedra sinica transitionally crossed blood brain barrier (BBB) and the distribution were investigated. The concentrations of Ephedra alkaloids in rat central nervous system (CNS) were determined to acquire the distribution characteristics and differences in cerebral cortex, cerebellum, hippocampus, striatum, medulla oblongata and hypothalamus. It was founded that pseudoephedrine, norephedrine, norpseudoephedrine, methylephedrine (methylpseudoephedrine) were able to cross BBB fast via gastro-intestinal tract after administrated with Ephedra sinica. Cortex and hippocampus was the main distribution region, followed by hypothalamus, striatum and cerebellum, in which medulla oblongata had the least. The distribution of various alkaloids, as AUC_{0-t, brain}/AUC_{0-t, blood} was ephedrine > methylephedrine > demethyl ephedrine. Alkaloids in Ephedra sinica crossed BBB rapidly, showing the regional distribution tendency in central nervous system, and the distribution was diversity. This group of data provides distribution of bioactive constituents of Ephedra in CNS.
