Objective To investigate whether the high intensity focused ultrasound (HIFU) for treating uterine fibroids and adenomyosis leading to pelvic adhesion .Methods 1 672 patients with definitely diagnosed uterine fibroids or adenomyosis were col‐lected and divided into the non‐HIFU group(1 560 cases) and HIFU group(112 cases) according to whether performing HIFU op‐eration .The pelvic adhesion situation in each case was scored according to pelvic adhesion scoring system .Then the results were performed the statistical process .Results No statistically significant differences were observed in the pelvic adhesion situation and pelvic adhesion degree between the HIFU group and the non‐HIFU group (P>0 .05) .The single factor analysis of factors possibly causing pelvic adhesion showed that the age ,past history of endometriosis ,operation and pelvic inflammatory disease ,lesion size and dysmenorrhea history affected pelvic adhesion ,the differences were statistically significant(P<0 .05) .But in the multi‐factor corre‐lation analysis ,various factors in the HIFU group were excluded(P> 0 .05) ,while the operation history and pelvic inflammation disease history had correlation with pelvic adhesion (P<0 .05) .Conclusion HIFU dose not cause pelvic adhesion in treating uter‐ine fibroids and adenomyosis .

Randomized controlled trial(RCT),considered as the strongest evidence-based method in clinical trial,can provide first-hand scientific evidence for clinical practice and instruct clinicians to make correct decisions in practice.This article introduces the principles for RCT designing,analyzes the common problems concerning RCT in clinical practice and the common mistakes made in RCT statistical methods.It is concluded that application of RCT method and correct statistical methods are of great importance in clinical medical research.

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.

Objective To research the position transition training effect of general practitioner of northeast district of Chongqing,and find out the problems and their reasons.Methods 326 students and 150 unit leaders were chosen to make a questionnaire survey(recycled 307,150).The Kirkpatrick model was also used for data analysis from 4 levels.The result was described in percentage.Results Reaction Level:42.02％(129/307) of the trainees were not satisfied with the time arrangement of clinical medicine training; Study Level:3 courses were at high failure rate 19.54％(60/307),22.8％(70/307),17.92％(55/307); Behavior Level:81.43％(250/307)of the trainees considered the training effective; Result Level:94.00％(141/150)unit leaders considered the training had a positive impact.Conclusion The time arrangement of clinical medicine training is mostly unsatisfied and the ability of instrument using and result interpretation is weak.Most people consider the position transition training is effective.

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.

The teaching material library of nutrition and food hygiene was established based on the concept of integrable ware.This paper discussed on the methods and the experiences.The establishing principle must be clear,knowledge points should be separated into parts accurately,courseware and other computerized teaching materials should be made into full use and convenient and efficient retrieval method must be established.In the future,teaching material library and platform construction should be improved and study of educational technology should be strengthened to improve teaching quality and adapt to modern teaching requirements.

Effective leadership is crucial for health organizations' performance and numerous western universities thus offer leadership courses or modules to their students.However,such education practice has not started in China.In order to optimize knowledge and skills of health service management practitioners,to content with requirements of health service organizations,to cope with dynamic organization environment,to implement health reform successfully and to realized sustainable development of health organizations,it is necessary to provide leadership course for students of health service management at Chinese universities.

This paper introduced the fair benchmarks of evaluation framework for health system constructed by Daniels, et al, and its developmental application in evaluation of health resource allocation fairness .After introdu-cing the resources rational allocation of public health fair benchmarking fixed framework , this paper assessed the al-location of health resources according to the fixed framework .China has achieved good results in public health serv-ice interventions .But public sector governance , macro economic and social policy environment , factors such as ac-countability may restrict the improvement of the health care system .China's health expenditure allocations have un-fairness between provinces , urban and rural areas and different classes .China can use the new benchmark in the field of public health to promote the reform of health resource allocation fairness , make effective social health strate-gies.

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.
