Objective:To explore the efficacy and adverse reaction of TOMOX regimen combined with three dimensional conformal radiotherapy in the treatment of middle and advanced esophageal cancer. Methods:51 cases of hospitalized patients with esophageal cancer were selected from January 2013 to December 2015 in our hospital who were divided into observation group (n=27) and control group (n=24) by random number table method. The control group was treated with three dimensional conformal radiotherapy, and the observation group was added with the TOMOX scheme based on the control group. Compare the efficacy of the two groups, the control period, the survival period, the toxicity and side effects.Results: The rate of complete response(CR)and partial response (PR) in the observation group was significantly higher than that in the control group, the difference was statistically significant (P<0.05). The total effective rate of the observation group was 96.30%, which was significantly higher than that of the control group 58.33% (P<0.001). The 2 year control rate and 2 years survival rate of the observation group was significantly higher than that of the control group (P<0.05). The incidence of acute radiation pneumonia and gastrointestinal reaction in observation group was lower than the control group, the difference was statistically significant (P<0.05).The neuritis rate and leukopenia of observation group was lower than the control group, but the difference was not statistically significant (P>0.05). The rate of acute esophagitis in the observation group group was higher than that in the control group, the difference was statistically significant (P<0.05).Conclusion: TOMOX combined with three-dimensional conformal radiation therapy can effectively improve the short-term efficacy and long-term survival rate, reduce adverse reactions.

BACKGROUND:Currently, there is a lack of efficient, non-invasive way to transplant stem cels to the target organ or tissue. Exploring a way to guide targeting transplantation of stem cels and to improve the efficiency of stem cel homing is now one of focuses in the field of stem cels research.
OBJECTIVE: To establish a simple and feasible method to chemicaly modify the cel surface using biotin-streptavidin reaction system, and to evaluate the efficiency of this method to label bone marrow mesenchymal stem cels (BMSCs) and its effects on cel biological functions.
METHODS: Passage 3 BMSCs were obtained by whole bone marrow culture method and verified by flow cytometry. Biotin, streptavidin, sulfonated biotin-N-hydroxy-succinimide were used to equip the adhesion molecule ligand, sialyated LewisX (SLeX), to the BMSCs surface. The labeling rate of BMSCs was assessed using fluorescence microscope, the vitality of BMSCs was evaluated by trypan blue staining, and the proliferation of BMSCs was evaluated by cel counting kit-8 assay. Adipogenic and osteogenic inductions were used to evaluate the effect of the method on the multi-differentiation function of BMSCs.
RESULTS AND CONCLUSION: After culture for 2 weeks, passage 3 BMSCs were obtained and confirmed by expressing CD90, CD29 and lack of CD34, CD45. Biotin, streptavidin, sulfonated biotin-N-hydroxy-succinimide were successfuly used to equip sialyated LewisX (SLeX) to the BMSCs surface and had minor effects on the vitality, proliferation, and differentiation of BMSCs. This method was simple for surface modification and had a high modification rate of 88%. The homing of BMSCs modified by this method to the target organ or tissue could be greatly enhanced. Therefore, this method potentialy could have extensive and important applications.
