Neurogenic bowel is a syndrome that resulted from the denervation after spinal cord injury (SCI), and may influence the quality of life of SCI patients for the constipation and incontinence. It might be benefit of multidimensional bowel management including nu-trition, medicine and liquid, as well as stimulation, clyster etc. Surgery could be considered if necessary.

National Outline Program for Medium and Long-term Education Reform and Development (2010 -2020) points out the importance of cultivating the ‘excellent physicians' and the idea of ‘ constructing high-qualified and high-leveled clinical faculty is at the top priority' was put forward clearly at the ‘ working conference of the national mdical education reform' sponsored by both the ministry of education and the ministry of health.From the perspective of constructing clinical faculty adaptable to the new situation,this essay explored the importance of constructing clinical faculty under the new situation of medical education reform,summarized the achievements and experiences in the general hospital of Tianjn medical university and proposed some suggestions.

The hospital spirit is not only the spiritual support and vital source for staff, but also the concentrat-ed expression of ideology and faith, value orientation, moral trait, psychology tendencies, culture stereotypes, the unified will and code of conduct for all kinds of personnel.The party organizations are the best helmsmen to culti-vate and carry forward the hospital spirit, which reveals distinctive and profound medical ethical principles and norms.In this paper, taking X hospital as an example, we describe the core function of the party committee′s lead-ership and results in the process of breeding, inheritance and innovation of hospital spirit and reflect ethically so as to provide good references for the current hospital spirit cultivation and promotion.

Objective To discuss some expectation on reform of classroom teaching method for eight-year program medical education, in order to provide a basis for the evaluation and reform of classroom teaching method. Methods Investigation that mainly included expectation on reform of classroom teaching method, classroom teaching method of most expected application, and ex-pected value of classroom teaching method was investigated and analyzed with self-made question-naire, to total 78 medical students (22 of Grade 2008, 20 of Grade 2009, 20 of Grade 2010, 16 of Grade 2011) of eight-year program who had completed the stage before medical education in the uni-versity, and related 32 teachers. Software of SPSS 20.0 was used to make statistical analysis. Results In the survey, 55.8% students and 78.1% teachers hoped to reform the current classroom teaching methods (χ2=4.782,P=0.029). 61%students and 90.6% teachers expected comprehensive application of diverse method(χ2=15.464,P=0.017), including instruction combined with writing on blackboard, teaching by multimedia, PBL, inversion-type class, independent learning, a lot of questions for exami-nation, and so on. The value expectation (>60%) of classroom teaching method was multivariate, in-cluding to stimulate students' interest in learning, to cultivate ability of finding and solving problems, conducive to understanding of knowledge and memory, conducive to comprehension and memory of knowledge, conducive to cultivation of learning method, able to improve ability of creativity and criti-cal thinking, conducive to strengthening interaction and communication of teachers and students, to improve the subject consciousness of student in classroom, helpful to cultivate the spirit of teamwork, to improve the efficiency of teaching, and able to make full use of information technology. Conclusions For the diversified value demand and the highly expectation on reform of current classroom teaching method, more attention should be paid to evaluation and guidance on reform of classroom teaching method for eight-year program medical education.

Spinal cord injury has changed the function of human body and the way of life, and reduced the reserve capacity of the organs of various systems, which exceeded the body's repair ability itself, and overlapped with physiological aging and premature senescence appeared. This paper reviewed recent studies and analyzed the relation of the injured age, the chronological age, number of years after injury with dysfunction, predicted the function changes of them, and identified the factors related with their quality of life.

Objective To establish a capillary gas chromatography( GC)method for the determination of residual organic solvents in poly( lactic-co-glycolide)( PLGA),including methanol,acetone,dichloromethane,and toluene. Methods A capillary GC method was carried out. DB-624 capillary column(30 m× 0. 32 mm,1. 80 μm)with programmed temperature chromatography was employed. The initial temperature was kept at 40 ℃ for 8 min. Then the temperature was raised to 200 ℃ at a rate of 10 ℃·min-1 . The injection port temperature was 180 ℃,and the split ratio was 10:1. The carrier gas was nitrogen. The temperature of FID was set at 250 ℃,and the sample volume was set at 3 μL. Results Four residual organic solvents consisting of methanol,acetone,dichloromethane and toluene in PLGA were completely separated. The linear range of concentration of methanol,acetone,dichloromethane and toluene was within 10. 0-50. 0( r=0. 999 8 ),16. 7-83. 3( r=0.9998),2.0-10.0(r=0.9993),and3.0-14.8(r=0.9997)μg·mL-1,respectively.Therecoveryofmethanol,acetone, dichloromethane and toluene was 99. 9%( RSD=1. 5%),100. 8%( RSD=0. 9%),100. 1%( RSD=1. 1%),and 99. 5%(RSD=0. 6%),respectively. Six batches of samples met the requirements. Conclusion The method is proven to be sensitive and accurate after the validation. It is suitable for the determination of residual organic solvents in PLGA.

The paper reviewed the significance and methodology of building a hospital emergency response system, and recommended on coordinating hospital emergency response work. The practices to build emergency response norms include persistent improvement of hospital emergency response system,unifying hospital emergency pre-plan, scheduling emergency drills, training and assessment, performance appraisal, and quantified indicators. The paper also summarized such operation principles as system development, unified management, job division, standardized operation, and routine operations.

Objective To explore the feasibility of using irreversible electroporation (IRE)mediating HPV16 E6 shRNA into cervical cancer cell line SiHa,and to clarify the influence of their co-effect on the proliferation of SiHa cells and its mechanism.Methods A HPV16 E6 gene specific interference sequence was inserted in pGenesil-1 to build a interference vector.10 pulses of IRE with 800 V,100 μs,and 1 Hz were applied to the suspension of SiHa cells and vectors.According to the treatment factors,control group,IRE group,pGenesil-N group,pGenesil-N+IRE group,pGenesil-E6 group and pGenesil-E6 + IRE group were set up.The expression of green fluorescent protein (GFP)and transfection efficiency were confirmed by inverted fluorescence microscope 24 h after the vector was transfected by IRE,and the expression efficancy of GFP was calculated.The expression levels of E6 mRNA and protein were detected by RT-PCR and Western blotting method which was also applied to detect the expressions of P53 and PCNA.The proliferative activity of SiHa cells was determined by CCK-8 assay.Results Enzyme digestion and DNA sequencing verified that the vectors were correctly constructed.GFP was seen under inverted fluorescence microscope 24 h after IRE transfection.Compared with IRE group,the expression levels of E6 mRNA and protein were decreased detected by RT-PCR and Western blotting method after the vectors were treated with IRE,the P53 protein expression level was increased (P < 0.05),and the PCNA expression level was decreased (P <0.05).The CCK-8 assay results showed the proliferative activity of SiHa cells in pGenesil-E6+IRE group was decreased more obviously than that in pGenesil E6 group (P <0.05).Conclusion IRE can play the role of gene transfection of mediating HPV16 E6 shRNA into SiHa cells, and their co-effect can significantly inhibit the proliferation of SiHa cells.
