Objective To construct adenovirus vector harboring CTLA4Ig-IRES2-I?B? gene for the study of enhancement blockade of T cell costimulatory pathway. Methods The IRES2 fragment was cloned in to the shuttle plasmid pAdtrack-CMV-CTLA4Ig, and then the human I?B? fragment was constructed with the link of the IRES2 to the pAdtrack-CMV-CTLA4Ig. Subsequently, adenovirus vector harboring CTLA4Ig-IRES2-I?B? was constructed by homologous recombination in E. coli BJ5183, and recombinant vector was packaged and propagated in 293 cells. Results The recombinant CTLA4Ig-IRES2-I?B? adenovirus was constructed by homologous recombination and identified by PCR and restrictive enzyme digestion methods. Conclusion The recombinant CTLA4Ig-IRES2-I?B? adenovirus may be used as a novel immunosuppressive agent for gene therapy in organ transplantation.

ObjectiveTo explore the video-urodynamic characteristics of neurogenic bladder caused by suprapontine neuropathy.Methods65 patients with neurogenic bladder caused by suprapontine neuropathy were involved from February 2004 to May 2009. The data were analyzed retrospectively, including clinical manifestation, diagnosis, voiding management, ultrasound, uroflow, post void residual, filling cystometry, pressure-flow study and the radiology. The results were compared with those of the suprasacral spinal cord injury.ResultsNo significant difference was found in the urodynamic parameters between various kinds of suprapontine neuropathy. Compared with suprasacral spinal cord injury, suprapontine neuropathy had less detrusor-sphincter dyssynergia, less reflux and upper urinary tract dilation but more normal micturiton reflex.ConclusionThe main video-urodynamic characteristic of neurogenic bladder caused by suprapontine neuropathy is detrusor overactivity, and the detrusor-sphincter dyssynergia, reflux and upper urinary tract dilation are rare.

Objective To compare the efficacy and prognosis of epirubicin combined with paclitaxel and epirubicin combined with docetaxel in the treatment of breast cancer.Methods Patients in the study group were treated with epirubicin and paclitaxel, while the control group was treated with epirubicin plus docetaxel.Results The two groups of breast cancer patients by the end of the treatment were valid for 5 years of follow-up, five year survival rate(86.67%)than the control group(68.89%), the study group the recurrence rate(4.44%)than in the control group(15.56%), the data had significant differences(P<0.05).Conclusion The epirubicin is conducive to breast cancer patients for better disease control effect and prognosis than star, paclitaxel combined with chemotherapy.

To explain how to ensure and improve the quality of the clinical practice teaching for the clinical institutes,we expatiate on the practical experience in the hospital from enhancing the practice teaching management,improving the teaching consciousness,meliorating the teaching environment and reforming the method.

Objective To investigate physical activities of preschool children by gender and to explore the effects of activity type on bone indexes.Methods During 2009 and 2010,397 preschool children of 3-5 years old were randomly selected from 4 kindergartens in Chengdu Province of China.Ultrasound bone analyzer was used to assess children's bone mass.A physical activity questionnaire was completed by parents to evaluate physical activities at leisure time.Student's t test and least square regression were used for data analysis.Results Concerning activity types,boys spent more leisure time on running and Wushu than girls did (t values were 1.94 and 2.84,respectively ; both P ＜ 0.05).However,girls spent more time on dancing (0.78 h),jumping rope (0.08 h) and manual labour (0.22 h) each day (t values were-9.50,-3.43 and-1.92,respectively; all P ＜ 0.05).The weekly total exercise time and energy consumption per unit of body weight of girls vs.boys were 7.29 vs.6.51 h and 127.57 vs.113.85 kJ (t values were 2.63 and 2.04,respectively ; both P ＜ 0.05).About per day time on sleeping and per week time on watching television,there were no significant difference between boys and girls (t =0.180,0.520;P ＞0.05).But boys spent more time on electronic game and computer than girls (t =0.760,2.510;P ＜ 0.05).The normalized correlation coefficient for bone mass and moderate physical activities or jumping was 0.184 and 0.275,respectively (both P ＜ 0.05).Conclusions Our data suggest that preschool children's bone volume may be positively correlated with moderate physical activities and jumping activities.Introducing some moderate physical activities or activity appliance,toys and playing fields as well as increasing professional training might be helpful.

chronic cervicitis(0%),(P=0.000).The positive rates of EPMMPRIN overexpression in metastatic lymph nodes was 54.5%(12/22),no difference was found from corresponding primary tumor(72.7%,P=0.210).But EMMPRIN overexpression in primary tumor was related to lymph node metastasis(P=0.026),no relationship was found between EMMPRIN expression and other clinical-pathological parameters.Univariate analyses revealed that EMMPRIN expression did not correlate to tumor-specific survival.In contrast,lymph vascular space invasion,deep stromal invasion and lymph node metastasis were significantlyassociated with poor prognosis.In multivariate analysis,lymph-node metastasis was the independent prognostic factor for tumor-specific survival(P=0.006;HR=0.038;95% confidence interval,0.0190.763).Conclusion:EMMPRIN overexpression may play an important role in progression of human cervical cancer,and in the development of cervical cancer from CIN.

OBJECTIVE:To promote rational use of traditional Chinese medicines. METHODS:The practical importance of applying basic pharmacoeconomic theory to the rational use of traditional Chinese medicines was analyzed and the measures regarding how to apply the pharmacoeconomic theory to guide rational use of traditional Chinese medicines were put forward. RESULT & CONCLUSION: It is quite necessary and practical to apply the basic pharmacoeconomic theory to the rational use of traditional Chinese medicine, which plays a positive role in promoting rational use of traditional Chinese medicines.
