There are still two outstanding problems in comprehensive quality assessment index system of clinical medical undergraduates:contents of assessment is incomprehensive and every index has no quantitative research based weight.This article elaborated on a complete index framework,covering required knowledge,abilities,attitude,morality of clinical medical undergraduates and proposed a set of methods and processes,including literature research method,system analysis method,brainstorming,expert interviews,Delphi method,and some statistical methods,providing a theoretical basis for the development of comprehensive quality assessment index system for clinical medical undergraduates.

Objective To explore the response inhibition ability of oppositional defiant disorder symptoms children. Methods Subjects were 27 oppositional defiant disorder symptoms children and 27 normal children. They were asked to complete the stop signal task,go/no go task and the Simon task. Results The delay time of stop reaction (SOA,(260.27 ±69.12)ms) and go reaction time( (554.31 ±55. 81 )ms)of the oppositional defiant disorder symptoms children were shorter than the control group, the difference was significant (P＜0. 05). However,the stop reaction and interference control ability were no significant difference between these two groups. Conclusion Oppositional Defiant Disorder symptoms children's poor prepotent response inhibition ability is cognitive mechanism of their impulsive behaviors.

Objective To investigate the association between systemic lupus erythematosus(SLE) and polymorphism of cytotoxic T-lymphocyte antigen 4 gene(CTLA-4) and the effect on ANA and anti-dsDNA antibody.Methods The A/G substitution was investigated in the exon 1 position 49 in 92 SLE patients and 60 controls by PCR restriction fragment length polymorphism(PCR-RFLP).ANA and anti-dsDNA antibody were examined by indirect fluorescence immunoassay.Results SLE patients had significantly higher frequencies of the CTLA-4+49GG allele than controls(P

Objective:To investigate the effects of mycophenolate mofetil(MMF)on the expression of endothelial CD40L and lymphocyte-endothelium adhesion.Methods:HUVEC was used for adhesion assay and CD40L detection.The effect of mycophenolic acid(MPA),an active metabolite of MMF,was observed in the study.HUVEC were treated with TNF-? or/and MPA for 24 hours.The lymphocyte-endothelium adhesion was detected by Rose Bengal staining.After treated with TNF-?,rIFN-?,and LPS,HUVEC CD40L expression was detected.HUVEC was treated with any of the modulators or each combined with MPA,respectively for 24 hours and different doses of MPA combined with LPS were also designed to stimulate HUVEC for 24 hours.The expression of CD40L on HUVEC was detected by cell-ELISA method.Results:MPA inhibited adhesion to lymphocytes of the HUVECs of either resting or stimulated with TNF-?.The cytokines used in the study induced expression of CD40L on HUVECs.MPA did not inhibit CD40L expression on resitng HUVECs,whereas it inhitbited CD40L expression induced by TNF-?,rIFN-?,or LPS,and the inhibition of CD40L expression on the cells induced by LPS was shown in dose of MMF-dependnet pattern.Conclusion:Endothelial cells express a low level of constitutive CD40L that is increased by treated with simple cytokines.MMF inhibits interactions between endothelial cells and lymphocytes by suppressing the expression of CD4OL on endothelial cells.

Cbf?1 gene encodes an osteoblast specific transcription factor that regulates osteoblast differentiation and bone formation. The Cbf?1 gene contains 9 exons, however, the alternative splicing of its exons leads to genesis of multiple Cbf?1 isoforms with differences in transactivation potentials. Several signal transduction pathways, such as Ras MAPK pathway, cAMP pathway, or Smads DPC4 pathway, are involved in regulating Cbf?1 activity or its expression. These studies open new doors in pharmacological control of bone formation and gene or cell therapy of slowing the progression of osteoporosis.

Objective To explore the related factors of senile acute pulmonary thromboembolism(PTE) patients,and to observe the prognosis and analyze the strategy of control and prevention to reduce the incidence. Methods 50 elderly patients with acute PTE were selected,related factors were analyzed by using the retrospective investigation,and the prevention and control were administrated.Results The mainly disease occurred of the elderly patients with acute PTE were combined with chronic diseases 42% (21 /50),with lower extremity DVT 26.00%(13 /50)and with recent trauma,fracture and operation 20%(10 /50).Elderly patients with acute PTE who were ≥70 years of age and lying in bed the time≥1 month,were 58%(29 /50)and 62%(31 /50),which were higher than those of the other age <70 years old and lying in bed time <1 month of patients,the difference was statistically signifi-cant(χ2 =9.26,9.80,all P <0.05).Conclusion The related risk factors for elderly patients with acute PTE mainly correlate with age,lying in bed time,chronic diseases,patients with lower extremity DVT and recent trauma,fracture, operation,the variety of factors and overlap each other.Mastering the variety factors of PTE in the nursing process,and taking effective measures to prevent and control the factorscan reduce or avoid the occurrence of acute PTE,and im-prove the prognosis of the patients.

Encephalopathy of prematurity is still an important reason which affects the survival and quality of life of preterm infants. During hospitalized in neonatal intensive care unit(NICU),a variety of environmental factors such as noise,light,too much tactile stimuli,pain,and maternal - infant separation all will affect the development of preterm infants' brain,leading to encephalopathy of prematurity. Therefore,need to attach importance to the effects of NICU environment on the growth and development and the neurological function of preterm infants,try to optimize the environment of NICU,to reduce the incidence of brain injury of prematurity,improve the long - term prognosis of pre-term infants.
