OBJECTIVE:To provide reference for strengthening the cultural construction and promoting the cultural develop-ment of TCM in Chongqing. METHODS:Questionnaire was adopted to investigate the status quo and cognition of some citizens, staffs in medical and health institutions for the cultural construction of TCM in public TCM medical and health institutions above Grade Two in Chongqing,and the data was statistically analyzed. RESULTS:Totally 45 questionnaires were sent out for TCM med-ical and health institutions,45 were effectively received with effective recovery of 100%;3 500 were sent out for the citizens,2 250 were effectively received with effective recovery of 64.29%;1 100 were sent out for the staffs in TCM medical and health institu-tions,702 were effectively received with effective recovery of 63.82%. In terms of cultural construction in surveyed institutions,or-ganization,principles and unit markings carried out a relatively high proportion in the core cultural soft power construction,the de-velopment of behavioral norms system carried out a relatively low proportion;and the proportion was higher in the hardware envi-ronment construction. In terms of the cognition of surveyed citizens for the TCM culture,62.98% believed in TCM;the first rea-son for choosing TCM was its less side effects(24.76%);89.42% thought it was necessary to keep in good health. In terms of the cognition of surveyed staffs for the cultural construction of TCM,81.91%thought the TCM culture was taken seriously in their hos-pital;60.54% showed great satisfaction with the cultural construction of TCM;only 23.08% was very familiar with the concept of TCM core values;the surveyed staff thought the main problems in the cultural construction of TCM were lack of facilities (69.09%)and talent personals(44.59%). CONCLUSIONS:The organization,principles,unit markings and facilities in Chongq-ing TCM medical and health institutions are taken seriously,while the behavioral norms system needs to be strengthened;the citi-zens’cognition for TCM culture should to be improved,as well as the staffs’TCM cultural awareness in TCM medical and health institutions.

Objective To investigate the relationship among social anxiety,fear of negative evaluation and self-esteem and supply reference for psychological health education.Methods We adopted Social Avoidance and Distress Scale(SAD),Fear of Negative Evaluation Scale(FNE)and self-esteem(SES)scale to investigate nursing students in a certain university and college.Then we analyzed the investigation results. Results The scores of SAD and SES of nursing students with different education background were distinctly different(P<0.05).The score of SAD was positively correlated with that of SES(r=0.483,P<0.05)and FNE(r=0.316,P<0.01).Conclusion We should strengthen the cuhivation of serf-esteem for nursing students and help them to get rid of fear of negative evaluation and conquer social anxiety.

BACKGROUND:The use of neural stem cels provides a new approach for nervous system functional reconstruction and nerve regeneration. How to solve the induced differentiation of neural stem cels is stil a research hotspot.
OBJECTIVE:To investigate the differentiation of rat neural stem cels into neurons and dopaminergic neurons under induction of glial cel-line derived neurotrophic factor gene.
METHODS:PcDNA3-GDNF-GFP plasmids were constructed and transferredvia lipidosome into rat embryonic neural stem cels. Differentiation of neural stem cels after transfection was identified under a fluorescence microscope. Immunofluorescent staining was used to detect expression of β-tubulin III and tyrosine hydroxylase.
RESULTS AND CONCLUSION:At 3 days after transfection, green fluorescence was observed in the transfected cels that were globular. At 7 days after transfection, the proportion of neural stem cels differentiating into neurons and dopaminergic neurons were significantly increased. These results indicate that the glial cel-line derived neurotrophic factor gene can induce the differentiation of neural stem cels into neurons and dopaminergic neurons.
