Constructivism educational theory can provide a useful guidelines for health law education,this article finds the association of constructivist theory for health law education reform,and combined the with application of relevant theories on teaching practice experience,it also discusses how to provide a real promotion for the"students'first"concept.

Objective In order to identify cytotoxicity and specificity of the suicide gene systems which vascular endothelial growth factor receptor 2(KDR) and CMV were used as promoters respectively. Methods Two cell lines, HUVEC and CNE-2, one expresses KDR highly,another doesn't, were used as target cells for identifying the cytotoxicity and specificity of recombinant adenoviral vectors with herpes simplex virus thymidine kinase (HSV-tk) gene expression driven by KDR promoter and CMV promoter respectively (pAdKDR-tk and pAdCMV-tk) in Vitro by adding GCV. Results HUVEC and CNE-2 showed similarly sensitivity to GCV when they were transfected by pAdCMV-tk. However, They shown different sensitivity to GCV when they were transfected by pAdKDR-tk. When HUVEC was transfected in high MOI (MOI=100) and concentration of GCV was 50 ?g/ml, The cell growth rate decreased to (23.12?4.90)% .On the contrary, CNE-2 cells growth rate remained as high as (70.46 ?3.27)%. Conclusion Two kinds of cell line CNE-2 and HUVEC can be killed by pAdCMV-tk suicide gene system, but pAdKDR-tk suicide gene system only can kill HUVEC cell line. The result implied that pAdKDR-tk could kill the cells that express KDR specifitly.

Objective To evaluated the treatment results of late-course accelerated hyperfractionated radiotherapy combined with chemotherapy for advanced esophageal carcinoma. Methods 72 patients with advanced esophageal cancer were randomized into two groups. The late-course accelerated hyperfractionated radiotherapy combined with chemotherapy(LCAF+CT)group received the induction chemotherapy for two cycles, followed by conventional fractionation radiotherapy to a dose of 36 Gy, then changed into accelerated hyperfractionated radiotherapy to a total dose of 60 ~ 66 Gy. The conventional fractionation radiotherapy combined with chemotherapy(CF+CT)group received the chemotherapy that it was similar to LCAF+CT group, and used the conventional fractionation radiotherapy to a total dose of 60 ~ 66 Gy. Results The 1-, 3- and 5-year survival rates were 82.3 %, 51.6 %, 38.2 % in the LCAF+CT group, and 73.8 %, 31.5 %, 18.6 % in the CF+CT group. The differences of 3- and 5-year survival rates were statistically significant (P 0.05). Conclusion Late-coures accelerated hyperfractionated radiotherapy combined with chemotherapy might improve the treatment efficacy of advanced esophageal cancer and lengthen the suvival time. The toxic and side effects of LCAF+CT group were more severe than those of CF+CT group, but they were well tolerable.

OBJECTIVE: To investigate the influential factors associated with the long-term effect of allergic rhinitis (AR) specific immunotherapy (SIT). METHOD: Retrospective analyzed the following visual analog scale(VAS) before and after the specific immunotherapy of 219 patients with allergic rhinitis. Logistic regression and pair t-test were used to explore the key factors influencing the prognosis. RESULT: (1) The gender and the VAS before specific immunotherapy (P < 0.05) were associated with the long-term effect of allergic rhinitis specific immunotherapy, while family history, the age of specific immunotherapy, number of allergens and stitches and with other allergic diseases (P > 0.05) were not associated with the long-term effect of specific immunotherapy; (2) Compared VAS of different endpoints with VAS before the treatment,there were significant differences. The primary endpoints were the time following no more than half a year (total effective rate: 50.0%), half a year to 1 year (total effective rate: 51.7%), 1 to 2 year (total effective rate: 47.1%), 2 to 3 year (total effective rate: 54.5%) and over 3 year (total effective rate: 40.7%). CONCLUSION Apart from the gender and the VAS before specific immunotherapy,genetic and other factors can not significant influence the long-term effect of specific immunotherapy. The effect of specific im- munotherapy seems to last for 3 years at least. Increasing stitches can not improve long-term effect of SIT,but it can consolidate the effect. The long-term effect of specific immunotherapy tends to drop off with fluctuations over time and the higher of VAS before SIT,the better effect of long-term SIT. Further more, the long-term effect of SIT of male is worse than female. In consequences, we speculate epigenetics related to the interaction between environmental factors and genetic factors plays an important role in the long-term effect of allergic rhinitis specific immunotherapy.

AIM: To investigate the mechanism underlying insulin-stimulated increase in glucose uptake during low-flow myocardial ischemia. METHODS: The expression of myocardial GLUT1 polypeptide was determined by semiquantitative immunoblotting. The expression of GLUT1 mRNA was determined by semiquantitative Northern blotting. RESULTS: After infusing insulin during low- flow myocardial ischemia for 8 h,the expression of both GLUT1 mRNA and GLUT1 polypeptide was significantly higher in experimental myocardium than that in normal myocardium. The glucose uptake was upregulated at the same time in the exprimental myocardium. CONCLUSION: Insulin enhances the expression of GLUT1 mRNA and GLUT1 polypeptide in ischemic myocardial regions. GLUT1 expression may be an important mechanism by which myocardial cells enhance glucose uptake and metabolism during low-flow myocardial ischemia. [

OBJECTIVE: The safety of rush immunotherapy (RIT) in Chinese allergic rhinitis (AR)patients is unknown. The purpose of this prospective was to assess the safety differences between RIT and conventional immunotherapy in Chinese AR patients, and then discuss the clinical application feasibility of RIT. METHOD: A one-year study period was set for this study. The enrolled patients were divided into 2 groups according to their preference of therapy: RIT or conventional immunotherapy using standardized house dust mite allergen vaccine. For safety evaluation, the local and systemic adverse reactions were recorded throughout the both groups initial phase. Week 0 (W0), Week 2 (W2), Week 5 (W5), Week 17 (W17) were set as observation time points for leukotriene (LT-B4) and so on. The Generalized Mixed Linear Model with SPSS13. O and the chi-square test with SAS 9. 1.3 were used for Statistics. RESULT: Fifty-two cases were enrolled into the RIT group, of which 49 patients have completed the established treatment study, and 3 cases were lost to follow-up. In the conventional immunotherapy group, 35 cases were enrolled, of which 32 have completed established treatment study, and 3 cases were lost to follow-up. The local and systemic adverse events of AR RIT appeared to be similar to those of conventional therapy and LT-B4 was descended steadily in the two groups. CONCLUSION Processed in advance Chinesear with drugs, RIT is similar to the safety of conventional immunotherapy.
