Objective To evaluate the outcome of combination of intensive preconditioning regimen allo-HSCT with imatinib for treatment of Ph chromosome positive acute lymphocyte leukemia (ALL). Methods Between 2009 and 2010, 8 patients diagnosed as Ph+ ALL received allo-HSCT from HLA identical sibling during complete remission. Imatinib was added into the therapies of 5 patients.Seven patients received the intensive preconditioning regimen based on BuCy2, one patient received the regimen of TBI-Cy. A median of 6. 02 × 108/kg mononuclear cells and 3. 14 × 106/kg CD34+ cells were transfused. GVHD prophylaxis included cyclosporine A and methotrexate. Results All patients were well tolerant to the regimen without serious regimen-related toxicity. The median time of ANC≥0. 5 × 109/L was 15. 5 days, and that of PLT≥20 × 109/L was 19 days. Thirty days after allo-HSCT, all patients got donor engraftment successfully. Among 8 cases, 4 cases presented acute GVHD, 2 developed degree Ⅰ , one developed degree Ⅱ , and one developed degree Ⅳ. Seven patients were alive 100 days after allo-HSCT, 3 of whom presented chronic GVHD. At the end of following-up period, 6 patients were alive, among them, 3 patients were alive without relapse; 3 patients relapsed; Two patients died, one from acute GVHD, and one from leukemia relapse. Conclusion Combined intensive preconditioning regimen allo-HSCT with Imatinib was an effective treatment for Ph+ ALL, but the effect of anti-chronic GVHD of imatinib should arouse certain attention.

This study aims to investigate the relationship between odor and contents of the chemical compounds in Lonicera japonica, including chlorogenic acid, galuteolin and polyphenols. High performance liquid chromatography (HPLC) was applied to determine the contents of chlorogenic acid and galuteolin in L. japonica. The ponptent of polyphenols was determined by UV-Vis Spectrophotometry. Electronic nose was used to extract and measure the odor of L. japonica. Then SPSS 17.0 software was employed for data processing. There is a significant positive correlation between the comprehensive index value of aroma and the contents of chlorogenic acid and polyphenols. The regression equations have been established. However, the relationship between the comprehensive index value and the content of galuteolin is not obvious. This is proof that the odor of L. japonica has close connection with the chemical compounds. Therefore, this research offered a new method for initially determine or predict the content of the chemical composition in L. japonica,

Objective To analyze the outcome of idarubicin-intensified myeloablastive conditioning regimen in allogeneic peripheral blood stem cell transplantation (allo-PBSCT) in patients with myelodysplastic syndromes (MDS). Methods From August 2004 to July 2009, 12 patients with MDS were treated with alIo-PBSCT following the idarubicin-intensified conditioning regimen. The conditioning regimen was idarubicin (15 mg/m~2), continuous intravenous infusion for 20 h, days-12 to-10; busulfan (0.8 mg/kg), intravenous infusion every 6 h, days-6 to-4; cyclophosphamide (1.8 g/m~2), intravenous infusion every 6 h, days-3 to-2; cyclosporine A combined with short-term methotrexate was used for the prophylaxes of acute graft versus host disease (aGVHD). Results All twelve patients achieved Trilineage engraftment, and were well tolerated to this regimen. Eight patients survived, and the overall survival was 66.7%, disease-free survival (DFS) 58.3%. Two patients relapsed. OS for neither WHO subgroups nor IPSS subgroups had statistically significant difference. Conclusion Allo-PBSCT with idarubicin-inteusified conditioning regimen is an effective treatment with reduction of the relapse rate for MDS patients.

Objective To retrospectively analyze and compare the curative outcome of hematopoietic stem cell transplantation (HSCT) from HLA identical siblings vs intensive immunosuppression therapy (IST) for severe aplastic anemia (SAA).Methods From January 2008 to December 2010,41 patients with severe aplastic anemia were treated with related HSCT (n =14) or IST (n =27) which combined antithymocyte globulin (ATG) with cyclosporine-A (CsA) therapy.Results All the patients receiving HSCT reached complete response.Among the patients receiving IST,21 patients could be responsive to the therapy,and 2 patients died.There was significant difference in the response rate between HSCT group and IST group (100 ％ vs 77.8 ％,P＜0.01 ).Conclusion With the improvement of HSCT technology,the curative outcome of HSCT from HLA identical siblings for SAA is much better than IST.

AlM: To analyze personality traits in preoperative patients who undergolaser in situ keratomileusis ( LASlK) and to provide psychological basis for the selection of refractive surgery.
METHODS: Eligible patientswere seeking customized LASlK (group A n=53), conventional LASlK(group B n=75)and non-operation patients with ametropia (group C n=71 ) , who completed 16 personality factor questionnaires (16PF). Statistical analyses were performed with one-way ANOVA by SPSS11. 0 software package.
RESULTS: Compared to group C, patients in group A scored high on dominance and tension levels, and low on emotional stability level(P<0. 05), while patients in group B were more venturesome and more experimenting, but were less vigilant ( P<0. 05 ). Additionally, there were statistical differences between group A and group B on dominance, gallantry and vigilance respectively(P<0. 05). CONCLUSlON: The data indicates that personality profiles of LASlK patients with refractive error influence their decision for correction. Patients need suitable psychological assessment before surgery who actively chose customized LASlK seem to be more assertive and suspicious.

Objective To investigate the meaning of expression of apoptosis related molecules NFKBp65 and p53 and GPX1-mRNA in patients with Keshan disease(KSD).Methods Sixteen chronic Keshan Disease patients were enrolled in KSD group according to electrocardiogram,chest X ray film and clinical examinations on 15,September in 2009,and 23 healthy people were included in control group from physical examination taken in The Second Affiliated Hospital of Xi'an Jiaotong University.Fresh blood(5 ml)was collected from antecubital vein of all subjects in the fasting state.Total mRNA and protein of blood sample were isolated using Trizol.GPX Assay Kit was used to detect GPX enzyme activity,and GPX1-mRNA expression was determined by SYBR Real-Time PCR.Meanwhile,expression of apoptosis related molecules NFKBp65 and p53 were determined by Western blot.Results GPX enzyme activity decreased significantly in KSD group[(108.61±14.10)U]compared with control group[(122.78±11.89)U,t=2.874,P<0.05],GPX1-mRNA level of KSD group(0.553±0.299)notably KSD group(0.802±0.057)compared with control group[(1.065±0.355),t=6.829,P<0.01].p53 increased in KSD group(1.604±0.191)compared with control group[(1.137±0.186),t=3.033,P<0.05].Conclusiom Decreased GPX1-mRNA expression may result in lower GPX enzyme activity of patients with KSD.Thus oxidative damage increases and cadioeyte apoptosis is activated by activating apoptosis signal pathway.

OBJECTIVETo evaluate efficacies of three commonly used oral drugs including Berbamine Hydrochloride Tablet (B), Qijiao Shengbai Capsule (Q), and Leucogen Tablet (L) (by single drug, two drugs or three drugs) combined with granulocyte colony-stimulating factor (G-CSF) for treat ment of chemotherapy related leukocytopenia in mice.

METHODSTotally 156 Kunming male mice were divided into the normal control group (A, n=24), the model group (B, n=24), the G-CSF group (C, n =24), the G-CSF+Q group (D, n=12), G-CSF+ B (E, n=12), the G-CSF+L group (F, n=12), the G-CSF + Q + B group (G, n=12), the G-CSF + Q + L group (H, n=12), the G-CSF + L + B group (I, n=12), and the G-CSF + L + Q + B (J, n=12). Mouse models of chemotherapy related leukocytopenia were established by intraperitoneal injection of cyclophosphamide (CTX). A G-CSF group was set up as a positive control. Mice were treated by a single oral drug, a single oral drug combined with G-CSF, and two or three drugs combined with G-CSF respectively, and the death rate calculated. Hemocytes [such as white blood cells (WBC) and its classification, red blood cells (RBC), platelet (PLT), hemoglobin (Hb)] were calculated by hematology analyzer. Mice were anatomized and important organs weighed. Organ indices were calculated.

RESULTSThere was no statistical difference in the mortality rate among all groups (P > 0.05). Compared with Group B, WBC was elevated in all other groups (P < 0.01). WBC and PLT were elevated most in Group J, Hb and RBC were also increased at the same time (P < 0.05, P < 0. 01). Compared with Group B, RBC increased in Group E, F, G, I, and J (P < 0.01); Hb obviously increased in Group C, E, F, H, I, and J (P<0.01). Compared with Group B and D, the promotion of erythroid hematopoiesis by G-CSF could be elevated in any group contained drug B and L (P < 0.05, P < 0.01). The spleen index of model mice could be significantly improved in Group C, D, and G (P < 0.01). The thymus index of model mice could be significantly improved in Group H (P < 0.05).

CONCLUSIONSThe best scheme to treat mice with chemotherapy related leukopenia or decreased three blood series was to administrate three commonly oral drugs combined with G-CSF. Authors speculated that G-CSF and Q might have a certain effect on CTX induced immune inhibition.
