The treatment for chronic myeloid leukemia is still a challenge,at present.Tyrosine kinase inhibitors can partially control chronic myeloid leukemia in blast crisis (CML-BC),but the effect is not durable.Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the only way that can cure CML-BC.This paper presents a review of the treatment before allo-HSCT for CML-BC,the selection of condition regimen,donor and hematopoietic stem cell,the monitoring of MRD post-transplant,the prophylaxis and intervention of relapse.

OBJECTIVE:To study influence factors of medical students’rational drug use in clinical practice and to provide references for improvement of medical educations and rational drug use. METHODS:The information was obtained by 325 designed questionnaire"questionnaire for prescription behaviors of medical students’rational drug use"performed by students in two medical colleges of Jiangxi Province and was inputted using Epidata3.0 software. SPSS13.0 software was adopted to analyze data by means of descriptive statistical analysis and multiple linear regression analysis methods. RESULTS & CONCLUSIONS:The level of medical students’rational drug use was just a little below the average level. It was positive correlated to the self-evaluation on instructors’conducting frequency and the achievements in medical course,but with negative correlation to the performances of rational drug use knowledeg. The achievements in medical course in self-evaluation has great impact on rational drug use behaviors while the performances of rational drug use knowledge has little impact on it.

Through thorough understanding of the pathophysiology of graft-versus-host disease (GVHD) and graft-versus-leukemia (GVL) effect, especial the effects of immune cells and cytokines, the article is designed to find out multiple ways to reduce GVHD and reserve or enhance GVL effect. Many kinds of cytokines are involved in the pathophysiologic mechanisms of GVHD and GVL effect. Different cytokines have different effects on GVHD and GVL effect. Immune cells play important roles in regulating GVHD and GVL effect. Studies shows that some cytokines and specific immune cells are able to reduce GVHD, as well as reserve or enhance GVL effect at the same time, which make the separation of GVL from GVHD can be achieved. On the whole, through thorough understanding of the mechanism of immune cells and cytokines in GVHD and GVL effect, we can find out multiple ways to reduce GVHD, as well as reserve or enhance GVL effect.

Objective To assess the effect of Ambroxol combined with Naloxone on respiratory insufficiency on premature infants. Methods A total of 168 premature infants treated from 2006 to 2009 in our hospital were divided into two groups randomly. Additionally to the conventional treatment, Ambroxol (5 mg pertime) combined with Naloxone (0.1mg pertime) intravenously injected 2 to 3 times one day for 3 to 5 days in the treatment group(86 cases). The control group (82 cases) was treated by routine Aminophylline injection,3- 5 mg/kg pertime, 2 to 3 times one day. Respiratory rates, regulately or not,breathholding, cyanosis and apnea,mechanically ventilated time,time of oxygen inhaling, time of hospital stay and the overall response rate were measured. Results The overall response rate was 80% (69/86) in the treatment group and 56% (46/82)in the control group, with significant difference between the two groups ( P ＜ 0. 05 ). Mechanically ventilated time,time of oxygen inhaling and hospital stay in the treatment group was (110.5±45.1) hrs, (169.3±58.6) hrs and ( 12±3) days, which were all significantly lower than that in the control group ( 181.1±81.2) hrs, (236.6±87.8)hrs and (16±5)days,respectively(P＜0.01 or 0.05). Conclusion Ambroxol and Naloxobe additional to conventional treatment could improve the respiratory function in premature infants with respiratory insufficiency safely with less side effects. Moreover,breathing machine could be removed to some extent,which made it more applicable in primary hospitals.

[ ABSTRACT] AIM:To explore the effects of romidepsin ( FK228) , a novel histone deacetylase inhibitor, on the effector and regulatory T cells in vitro.METHODS:As the reactive cells, lymphocytes, CD4 +T cells and CD8 +T cells were labelled with CFSE, and stimulated with anti-CD3 and anti-CD28 mAbs in the presence and absence of different levels of romidepsin (experimental group and positive control group), or PBS (placebo group).After 72 h, the proliferation of the cells was detected in different groups.The lymphocytes were stimulated with anti-CD3 and anti-CD28 mAbs in the pres-ence and absence of different levels of romidepsin ( experimental group and positive control group ) , or PBS ( placebo group) .After 72 h, the percentage of CD4+Foxp3 +T cells and the levels of related cytokines were detected in different groups.RESULTS:The proliferation of CFSE-labelled lymphocytes, CD4 +T cells and CD8+T cells triggered by anti-CD3 and anti-CD28 mAbs all were inhibited when cultured with romidepsin at concentrations of 1 μmol/L, 3 μmol/L and 5 μmol/L in a dose-dependent manner (P<0.05).Compared with placebo group, in the presence of anti-CD3 and anti-CD28 mAbs, 1 μmol/L romidepsin did not increase the percentage of CD4 +Foxp3 +T cells ( P>0.05 ) .When cultured with romidepsin at concentrations of 3 μmol/L and 5 μmol/L, the percentage of CD4 + Foxp3 +T cells was enhanced markedly ( P<0.05) .The levels of IL-10 and TNF-αin the supernatant were markedly increased in positive control group
and 3 experimental groups ( P<0.05 ) , and the levels of cytokines in different experimental groups were gradually de-creased with the elevation of FK228 concentration (P<0.05).The level of TGF-βwas slightly increased in positive con-trol group with no significant difference compared with placebo group (P>0.05).With the increase in the concentration of FK228 in different experimental groups, the TGF-βlevel was increased in a dose-dependent manner and there were signifi-cant differences in the 3 experimental groups.Meanwhile, significant differences existed between experimental groups and placebo group and between experimental groups and positive control group (P<0.05).CONCLUSION:Romidepsin in-hibits the proliferation of CD4 +and CD8 +effector T cells and increases the percentage of CD4 +Foxp3 +regulatory T cells. It may be related to the increased level of TGF-β, but independent of IL-10.
