Objective To observe the curative effect of esophageal cancer with three-dimensional conformal radiotherapy and acute adverse reaction. Methods 28 cases with esophageal cancer were received three-dimensional conformal radiotherapy from August,2008 to August,2009. The conformal radiotherapy was performed in the way of 200cGy/fraction,5 fractions/week,total dose of 60-64Gy,30-32fraction. In addition,the curative effect and acute adverse reaction were evaluated along the radiotherapy. Results The number of complete relief(CR) cases was 10, part relief(PR) was 15 ,no change was 3 ,and the overall relief(CR + PR) rate was 89.3%. The local control rate and the survival rate in the first year were 75.0% and 60.7%, and second year were 71.4% and 46.4%. The cases of 0 level acute radioactive pneumonia was 14,1 level was 8,2 level was 5,3 level was 1. The cases of 0 level acute radioactive esophagitis was 5, 1 level was 14,2 level was 7,3 level was 2. Conclusion Three-dimensional conformal radiotherapy was a very safe and effective way to treat esophageal cancer. Whether the therapy could improve the long-term survival rate was remained to be observed.

Increased catabolism, including reduced protein synthesis rates and increased protein degration rates, is common in patient with trauma and sepsis. There has been a long time search in how to reverse the increased catabolism. Besides nutritional support, people hope manipulation of anti catabolism hormone might reverse or at least ameliorate catabolism. Recent researches indicate that the GH IGF IGFBP axis plays a crucial part in regulating the metabolism of muscle protein on both basal and stress condition. This article aims to review the changes in GH IGF IGFBP axis and its clinical significance associated with trauma and sepsis.

OBJECTIVE:To analyze the cost of three schemes in treatment of unstable angina pectoris METHODS:88 patients with unstable angina pectoris were divided into three groups:group Ⅰ was given isosorbide,asprin,nifedipine and nitroglycerin;group Ⅱ was given isosorbide,asprin,nifedipine,nitroglycerin and red sage injection and group Ⅲ was given isosorbide,asprin,nifedipine,nitroglycerin and puerarin;then using pharmacoeconomic method,cost-effectiveness analysis was carried out RESULTS:The efficacy in the group Ⅱ and group Ⅲ was higher than that in group Ⅰ(P0 05),and the E/C(effectiveness/cost) of the three groups were 15 98,18 02 and 33 40 respectively Compared with group Ⅰ,?C/?E of group Ⅱ and Ⅲ were 24 66,83 90 respectively;Compared with group Ⅱ,?C/?E of group Ⅲ was 643 60 CONCLUSION:The scheme for group Ⅱ is the best one

Objective:To study the effects of artesunate on K562, K562 /ADM cell apoptosis and NF-κB p65 expression in hu-man leukemia. Methods: The effect of artesunate with different concentrations on K562 and K562 /ADM cell apoptosis at various times was studied by a flow cytometer. The effect of artesunate with 15 μmol·L-1 on NF-κB P65 expression in K562 was explored u-sing a Western blot method. Results:Artesunate showed little effect on K562 cell apoptosis, while exhibited notable effect on K562 /ADM cell apoptosis. K562 /ADM cells were more sensitive than K562 to artesunate at the concentration of 7. 5 μmol·L-1 and 15μmol·L-1(P<0. 01), and after 4-hour treatment with 15 μmol·L-1 artesunate, K562 /ADM cell apoptosis was much higher than K562(P<0. 01). Artesunate could reduce leukemia cell p65 expression at the concentration of 15 μmol·L-1. Conclusion:Artesu-nate can induce the apoptosis of leukemia cells by down-regulating the expression of p65.
