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.

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.

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.

BACKGROUND:Scaffold materials are the important part of tissue engineering bone, and the ideal biodegradation speed of the scaffold materials can be in accordance with the regeneration speed of bone formation in order to achieve a long-term stability. OBJECTIVE:To summarize the biodegradability of different types of currently available scaffold materials and its relationship with bone formation. METHODS:The PubMed and CNKI database were searched by the first author using the key words of “tissue engineering bone, composite scaffold, scaffold degradation” in English and Chinese for articles addressing biodegradability of scaffold materials and its relationship with bone formation published during January 1996 and December 2013. RESULTS AND CONCLUSION:Many scaffold materials under organic, inorganic and organic-inorganic categories have been available and the current studies focus on inorganic materials and organic-inorganic composite materials.In vivo andin vitro studies indicate the different characteristics and relative merits of these scaffold materials. Organic materials have a relatively slow degradation rate while inorganic materials can completely degrade but have an insufficient mechanical property. For organic-inorganic composite materials, further studies are needed.

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.

Objective To explore the features and relevant factors of ecological executive function in adults with id-iopathic or probably symptomatic epilepsy. Methods 120 adults with idiopathic or probably symptomatic epilepsy were compared strictly with 120 healthy controls of the same gender, age , marriage and educational degree. The differences in ecological executive function were compared between the two groups with the Behavior Rating Inven-tory of Executive Function-adult version( BRIEF-A);apply multiple stepwise linear regression analysis was used to explore the correlations between epileptic factors with projects of BRIEF-A. Results Compared with controls,the epileptics yielded higher scores significantly on all projects of BRIEF-A(P<0. 05):global executive composite,be-havioral regulation index,inhibition,shift,emotion control, self-monitoring, metacognition index,initiation, working memory,plan,organization,task monitor. Multiple stepwise linear regression analysis showed that four clinical fea-tures videlicet seizure type, seizure frequency, epilepsy control and antiepileptic drugs were closely related to BRIEF-A while factors such as course of disease,gender,age,marriage,educational degree,initial age were not rele-vant to BRIEF-A. Conclusion The ecological executive function of adults with idiopathic or probably symptomatic epilepsy impairment is affected by seizure type,seizure frequency,epilepsy control and antiepileptic drugs.
