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.

According to the programming characteristics under the SOC embedded environment,the dynamic auto-adapted bit stream technology,the intelligent interception technology,and the tele-control technology are utilized to realize the real time network communication of medical video with a variable bit stream from 1M to 4M as well as the tele-control of multiple communication protocols such as TCP,UDP and Multicast.

The popularization of home medical equipment facilitates the treatment and management of many diseases, improving the patient compliance. However, due to the absence of medical background, most of their users have various security risk in the course of reorganization, choosing, using and maintenance of the products. This paper analyzed the property of security risk in home medical equipment, and described the matters needing attention in the using of several common products.

Objective To provide references for epidemiology teaching reform by investigating scores of epidemiological exam and applications of epidemiologic course content in practice.Methods The epidemiological exam scores of students majoring in preventive medicine from 2004 to 2007 grade were statistically analyzed and questionnaire survey was carried out among students of 2006 and 2007 grade.Results The skewness of epidemiological scores from four garades were negative skew,and the kurtosis of 2007 grade was positive,the others were negative;there were statistical differences among the average scores of different grades(F=2.70,P＜0.05);there were statistical differences between 2004 grade and other grades in passing rate(x2=7.94,P＜0.008).Most of the contents applied in survey were prevention and control of infectious deseases(16.0％),prevention and control of chronic diseases(13.9％),surveillance of diseases(11.8％).Conclusions Epidemiology teaching reform should be enhanced and should integrate theory with practice.

[ 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.

OBJECTIVE: To analyze the literatures on grand mal epilepsy caused by levocarnitine,explore the causes of seizures, the clinical features and treatment measures in order to provide guidance for rational use of drug. METHODS: Included studies retrieved from CNKI and VIP in china journal of medicine from 1999～2009.Based on a grand mal epilepsy case caused by levocarnitine for Injection in our hospital, cases of grand mal epilepsy caused by levocarnitine reported in literatures were analyzed comprehensively. RESULTS: The clinical information of grand mal epilepsy cases reported in our hospital and literatures were analyzed as well as past medical history, usage and dosage, onset time, treatment method and efficacy. All patients were in the process of irrigation of Levocarnitine showed the typical clinical manifestations of grand mal epilepsy, after active treatment were both mitigation. CONCLUSION: The adverse reaction that grand mal epilepsy is caused by levocarnitine is rare,and pathogenesis is not clear but clinicians should pay attention to it.

Objective To study the urban elder people's cancer-spectrum in Chongqing from 1991 to 1998 in order to obtain the first-hand data and references for the prevention and the treatment of carcinoma in the seniles. Methods The data of population and death causes were collected with cluster sampling method in the communities of business, culture and industry in Chongqing. Their mortality rate, disease-specific mortality rate and the sequence of the death causes were analyzed. Results Their first death causes was cancer (mortality rate 811.95/105 persons, accounted for 21.25% of all death causes). The mortality rate of five cancers was as follows: lung cancer (282.45/105), esophagus cancer(119.47/105), liver cancer(108.41/105), stomach cancer (73.75/105) and intestine cancer (55.31/105). The prevalence of different cancer between male and female at different communiteis was different. Conclusions It is very important to strengthen the protection of the environment and advocate the healthy life mode in order to lower the mortality rate by cancer in urban seniles.
