Objective: To explore the differences between the internal social adaptation and external social behaviors of freshmen. Methods: Make a survey of 198 freshmen on the internal adaptation and external by General Well-Being Schedule and Undergraduate Social Adaptation Questionnaires. Results:Freshmen' social adaptation mainly involves three factors: interpersonal communication, the state of campus life and performance of studies. The Cronbach alpha of 3 factors were 0.82, 0.87 and 0.90,and the re-test reliability was r=0.73 (P

Objective:To study the cognitive features of text anxiety. Methods: The cognitive features of text anxiety were explored by exploratory factor analysis and confirmatory factor analysis on the basis of interview,questionnaire surveying and criterion.Results:There were 6 cognitive factors leading to test anxiety: self-test, worrying, magnifying conclusion, resistance, preparing, self-efficacy.Conclusion: The 6 factors of cognition about text are related to text anxiety

Pain is one of important topics in Bioethics.Pain,which looks like a simple physical symptom,involves the crucial ethical value.In Western bioethics,pain has been discussed for some decades.However,pain still hasn't been emphasized as an important topic in Chinese Bioethics world.Therefore,from bioethical perspectives,this article attempts to study pain under four subtitles: the notion of pain;some bioethical debates about pain;narrative of pain and illness,and pain: a way to go further for Bioethics studies.

In modern world,bioethics has become an international social movement since its inception during the mid-twentieth century.In the practices of clinical bioethics,methodology is the most crucial issue concerned by western scholars.Briefly,the article introduces and analyzes the empirical approach in contemporary European world,as well as explains the interaction between bioethics and naturalism.Based on current development of mainstream ethics,the article also tries to answer the question about "is and ought" in the background of clinical practice.The research aims at providing the ideas and experiences for the development of Chinese clinical bioethics.

The actuality of natural medicines in China,Europe,America,and Korea were explained, and analyzing existing problems of research and development of the natural medicines in China combing development trend of natural medicines,research trend,future direction,thought and methods for research of natural medicines were put forward in the paper.

MicroRNA (miRNAs) are endogenous,small and noncoding regulatory RNAs,which widely exist in eukaryotes.MiRNAs regulate the expression of target gene by translating inhibition or mRNA destabilization.MiRNAs have been recognized as a major regulatory fashion of post-transcriptional gene expression and play important roles in many cellular biological processes,including cellular proliferation,diffcrentiation,cell death.Alteration of expression and/or dysregulation of miRNAs are related to a wide variety of severe fundus diseases,such as diabetic retinopathy,age-related macular degeneration and retinoblastoma.This review aimed to provide a summary of the recent progress in the effect of miRNAs on fundus diseases.

BACKGROUND:Treatment and rehabilitation of spinal cord injury is a complicated problem,andthe reconstruction and remyelination of neural reflex pathwaysare the essentialprocess, during which oligodendrocytes play an important role in spinal cord injury repair.
OBJECTIVE:To observe theeffect ofoligodendrocyte transplantation for acute spinal cord injury in rats.
METHODS:Insulin-like growthfactor 1 induced bone marrow mesenchymal stem cels differentiating into oligodendrocytes, and those oligodendrocytes were transplanted into rats with acute spinal cord injury as induced cel transplantation group. Simple normal salineandnatural oligodendrocytes were transplanted into the rat injured spinal cord as control group and oligodendrocyte group, respectively. Rat behavioral changes were observed by inclined planetest and Basso-Beattie-Bresnahan (BBB) scores. Neurological recovery and survivalof the transplanted cels was detected and observed using spinal evoked potential and immunohistochemical staining, respectively.
RESULTS AND CONCLUSION:Compared with the control group, BBB scores and the criticalelevation angle oftheincline planetestsignificantly increased, latencies of spinal motor and sensory evoked potential were on the decline (P< 0.05), and there were no significant differencesin above indicators between the two groups at 4 and 8 weeks after transplantation. Moreover, survivedoligodendrocytes after transplantation could be found in the lesions of spinal cord in both two groups. In conclusion, insulin-like growth factor 1-induced bone marrow mesenchymal stem cels can differentiate into oligodendrocytesthat exact an excelentrole in acute spinal cord injury repair after transplantation, which achieve the equal clinical efficacy tothenatural oligodendrocytes.

Objective To construct the eukaryotic expression vector of Notch1intracellular domain,p3XFLAG?CMV7?NICD1,so as to prepare for the further research and exploration of effect of Notch1 on promoting epithelial?mesenchymal transition of human lens epithelial cells. Methods The cDNA fragment was reversely transcribed by RT?PCR from total RNA extracted from the SRA01/04 cells and was encoded with the specific am?plification?targeted NICD1was obtained from the SRA01/04 cells,then the cDNA fragment was inserted into p3XFLAG?CMV7 to transcribe Esche?richia coli DH5α. And the recombinant plasmid was extracted after bacterial screening by LB plating medium and confirmed by the restriction endo?nuclease digestion and DNA sequencing. Results The target gene obtained had the same molecular size as predicted. It was indicated that recom?bined p3XFLAG?CMV7 plasmid contained correct recombinant human Notch1 sequences and p3XFLAG?CMV7?NICD1 was constructed success?fully. The western blotting showed protein NICD1 expressed in SRA01/04 cells transfected with p3XFLAG?CMV7?NICD1. Conclusion The suc?cessful construction of p3XFLAG?CMV7?NICD1 will provide a foundation for a further study studies in on the effect relationship of Notch signaling pathway and in posterior capsular opacification(PCO)after cataract extraction.

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.
