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.

Objective To study the effects of early intervention on neonatal jaundice and body weight, thereby preventing the occurrence of hyperbilirubinemia in newborns. Methods 320 healthy newborns were randomly divided into the two groups of the intervention group and the control group, with 160 cases in each group. All neonates of the intervention group were given the early intervention, including early breast-feeding, formula milk before the adequate breast-feeding, swimming and massaging. There was no nursing intervention for the control group, only the general nursing. The first defecation time, the first yellow defecation time, body weight in everyday, bilirubin value per cutem were measured and recorded. Results The bilirnbin value of the intervention group was much lower than that of the control group. The difference had statistical meaning (P < 0. 01). The body weight of newborns in the intervention group was much higher than that of the control group 5 days after born. There was statistical difference between the two groups (P < 0. 01). Conclusions Early nursing intervention can mitigate the bilirubin value effectively, reduce the incidence rate of hyperbilirnbinemia in newborns, reduce the decrease of body weight in newborns, and raise the body weight on discharge.

Objective To optimize ambi-extracting and inclusion process of volatile oil from Chuanxiong Rhizoma and Angelicae Sinensis Radix. Methods With yield ratio of volatile oil and ferulic acid content in water extract as evaluation indexes, single factor experiments were used to study the extraction process. With the inclusion rate of volatile oil and yield of inclusion as evaluation indexes, saturated aqueous solution was used to L9(34) orthogonal experiments to reach optimum inclusion process. Results The optimum extraction process of Chuanxiong Rhizoma and Angelicae Sinensis Radix was extracted for 8 hours with 8 folds the amount of water, and without soaking. The validation experiments of extraction of volatile oil and ferulic acid content in water extract were 1.23 mL and 0.387 9 mg/g. The optimum conditions of inclusion process were as follows: volatile oil (mL): β-CD (g) was 1:8;inclusion temperature was 40 ℃; inclusion time was 3 hours. The validation experiments of inclusion rate of volatile oil and yield of inclusion were 74.89% and 72.81%. Conclusion Optimum ambi-extracting and inclusion process of volatile oil from Chuanxiong Rhizoma and Angelicae Sinensis Radix are feasible and stable, witch can provide certain supporting data for preparation production.

OBJECTIVETo investigate the role of allograft inflammatory factor-1 (AIF-1) in colorectal cancer (CRC) progression and explore the possible mechanism.

METHODSThe expression levels of AIF-1 in 70 CRC tissues and paired adjacent tissues were detected using immunohistochemistry and Western blotting, and the correlation of AIF-1 expression with the clinicopathological features of the patients was analyzed. In the CRC cell line SW480, the functional role of AIF-1 in regulating tumor progression was investigated by transfecting the cells with an AIF-1-overexpressing plasmid (AIF-1) and a negative control plasmid (NC). EdU proliferation assay and flow cytometry were used to assess the cell proliferation and cell cycle changes; Transwell migration assay and Annexin V-APC/7-AAD apoptosis assay kit were used to analyze the cell migration and apoptosis. The changes in the biological behaviors of the cells were observed after application of SB203580 to block the p38 MAPK pathway. The expression levels of CDK4, cyclin D1, P21, P27, MMP2, MMP9, Bax, Bcl2, Bcl-xl, p38 and p-p38 were detected using Western blotting.

RESULTSAIF-1 was down-regulated in CRC tissues compared with the adjacent normal tissues, and its expression level was positively correlated with lymph node metastasis (P=0.008), TNM stage (P=0.003) and tumor size (P=0.023). Overexpression of AIF-1 in SW480 cells significantly reduced EdU-positive cells and caused obvious cell cycle arrest in G1 phase (P<0.05). AIF-1 overexpression resulted in significantly lowered protein expressions of CDK4 and cyclin D1, enhanced expressions of P21 and P27, attenuated cell migration ability (P<0.001), and decreased protein levels of MMP2 and MMP9. AIF-1 overexpression also induced obvious apoptosis of SW480 cells (P<0.01), significantly increased the protein levels of Bax and p-p38, and decreased the protein levels of Bcl-2 and Bcl-xl; SB203580 significantly attenuated the apoptosis-inducing effect of AIF-1 overexpression.

CONCLUSIONAIF-1 plays the role of a tumor suppressor in CRC by inhibiting cell proliferation, suppressing cell migration and inducing cell apoptosis. AIF-1 overexpression promotes the apoptosis of CRC cells by activating the p38 MAPK pathway.

OBJECTIVETo investigate the antimicrobial activity of Pariet, Tekpron, Nexium, respectively, against Helicobacter pylori (H. pylori) in vitro.

METHODSAntimicrobial effects of these medicines were evaluated through detection of MICs for 3 H. pylori strains isolated from different countries.

RESULTSThe MIC(99) contents were 2.25 mg/L, 42.5 mg/L and 360 mg/L, respectively, for the three medicines. The strains under testing exhibited the same susceptibility to each medicine. Nexium did not inhibit the bacteria under the concentration of 3.6 - 36 mg/L with more and bigger H. pylori colonies seen when compared with controls.

CONCLUSIONSThe growth inhibitory activity appeared to be different among the three PPI medicines under investigation, with Rabeprazole the most potential agent of the three. Data suggested that the action of growth inhibition in vitro was resting on the characteristic of the given PPI as well as the supplements of the medicine.

OBJECTIVETo observe the effect of tanshinone IIA (TS IIA) pretreatment on the expression of the inflammatory factor IL-1β and RelA mRNA in rats with focal cerebral ischemia.

METHODSA total of 100 adult male SD rats were randomly divided into 6 groups, namely the model, ischemic preconditioning (IPC), TSIIA preconditioning, TSIIA treatment, sham-operated, and blank control groups. In the former 4 groups, rat models of focal cerebral ischemia were established with corresponding treatments. The expressions of IL-1β and RelA mRNA in each group were detected using RT-PCR.

RESULTSAll the groups showed expressions of IL-1β and RelA mRNA with the exception of the blank control group. Compared to the model group, TSIIA preconditioning group, TSIIA treatment group, and IPC group all had significantly reduced expression of IL-1β and RelA mRNA (P < 0.05). The expressions were lower in IPC group than in TSIIA preconditioning group and TSIIA treatment group(P < 0.05), and no significant difference was found in the expressions between the latter two groups.

CONCLUSIONThe protective effect of pretreatment with TS IIA against cerebral ischemia is related to the reduction of IL-1β and RelA mRNA expressions.
