Hypertension is a kind of chronic disease effecting many population, and its prevalence has a rising trend with the age. It keeps in a increasing trend in chinese population, and follows high rates of prevalence, mortality, morbidity and three low rates of wareness, treatment, control. Hypertension is caused by a number of factors, and its incidence is closely related with unhealthy diets. Its incidence may be decreasing gradually by changing lifestyles, taking healthy and reasonable diet. To provide some basic data of healthy lifestyles and diet for people, describe and summarize the relation of hypertension and diets in this article.

Objective To explore the relationship between the body mass index and health-related quality of life(HRQoL) of young students aged 18～25 years old. Methods 4696 students aged 18～25 years old from nine provinces and municipalities (Jiangsu, Anhui, Gansu, Qinghai, Fujian, Boijing, Jilin, Jiangxi and He'nan) were investigated. The HRQoL of students with different body mass index were compared with rank sum test and lo-gistic regression analysis. Results Obesity and underweight students scored lower in both physical component and mental component scores of SF-36. Compared to students with normal weight, odds ratios (ORs) of impaired HRQoL among obesity students significantly increased in both physical domain (OR=1.86) and mental domain (OR=1.90), while OR of impaired HRQoL among underweight students significantly increased only in physical domain(OR=1.21). Analysis for boys and girls scparately,OR of impaired HRQoL increased in physical domain among underweight boys(OR=1.37), and increased in mental domain among overweight girls(OR=3.85). Con-clnsion Different body mass index have different impact on young students' HRQoL. Both obesity and trader-weight could reduce HRQoL. But obesity have more impact on girls' mental domain than boys, and underweight have more impact on boys' physical domain than girls.

Objective To establish the evidence-based nursing educational programme for preventing ventilator-associated pneumonia (VAP) and evaluate the effects in critical care nurses. Methods The evidence-based nursing practice guidelines for preventing VAP from 2008 American Association of Critical Care Nurses was used as training materials,which guided the curriculum design. Seventeen critical care nurses were trained. The difference of the nurses' knowledge and practice was evaluated before and after training by an evaluation scale of nursing quality criteria for preventing VAP. Results After the training,nurses' knowledge and practice of preventing VAP were improved(Z=-3.624,P=0.000). Except the factor score of handwashing,there were significant differences on the factor scores of body position care,endotracheal tube care,enteral nutrition,maintaining the tube cuff pressure,oral care and ventilator equipment management (P<0.01). Conclusion The educational programme of evidence-based nursing for preventing VAP can improve the nurses' knowledge and practice of preventing VAP. Furthermore,it can promote the application of evidence-based nursing for preventing VAP,and thereby to improve the quality of nursing,and provide guidance for the training of critical care nurses and continuing education.

Objective To explore the decision-making process of medical students who turned the major from the medicine to other majors,and the related factors that hindered them continuing to study the medicine.Methods According to the design of interpretative phenomenon logical analysis,semi-structured in-depth interviews were used to collect the data.Participants were six undergraduate students who had moved from medical major to another major.Interviews were recorded on audio-tape with the students' permission and then transcribed verbatim.The transcribed interviews were analyzed according to six steps of interpretative phenomenological analysis.Results Even if the participants had left the medical major,they still expressed a strong sense of professional identity for the doctor.However,they also admitted that the professional process of medicine students was very hard and tired,and couldn't get the equal return for their payment.They thus were lack of confidence for the future.Some of the participants talked about the fact that they had been curious about the future of medical students.Internet and seniors were the main avenues for obtaining job-related information,but they were often plagued by the negative information.Education about career adaptation should be carried out as soon as possible,to strengthen the professional identity of medical students,and enhance their ability to defend against negative information,which could help to deal with the status of high turnover rate for medical students.Conclusion Based on the students' perspective,exploring the decision-making process of turning major for medical students will contribute to the educators taking effective strategies to improve the students' career identity,stabilize their professional thought,and reduce the loss of the medical students.

Objective To analyze clinical manifestation and identify prognostic factors in patients with acute respiratory distress syndrome (ARDS) caused by cytomegalovirus (CMV) pneumonia after kidney transplantation.Methods Fifty five kidney transplant recipients' data were analyzed in a case-control study of patients with a primary discharge diagnosis of ARDS caused by CMV pneumonia.Results The mortality of ARDS after kidney transplantation was 56.4%;when association with mechanical ventilation,it was 72.5%.In multivariate Logistic regression analysis,numbers of complications (odds ratioOR2.60,95% confidence intervalCI1.00~6.76),severity of diffuse infiltrates in chest X-ray (OR 11.83,CI 1.14~123.07),mechanical ventilation (OR 11.83,CI 1.14~123.07) were independent risk factors to death.Conclusion Even in modern era,kidney transplant recipients with ARDS after kidney transplantation are still at high risk for death.Numbers of complications,severity of diffuse infiltrates in chest X-ray,mechanical ventilation are associated with poor outcomes.

Objective To explore the biomechanis with different bone density by the pedicle screws fixation before and after fatigue test.Thus provide biomechanical basis for the clinical work.Methods A total of 27 fresh lumbar vertebrae samples of adult sheep (L1-L5) were equally divided into three groups,such as group A of decalcified with HCL 0 h,group B of decalcified with HCL 2 h and group C of decalcified with HCL 4 h,by using the random number table method,every groups was 9 models.Four screws was performed on the L4-L5 pedicle of vertebral arch of the three groups.Three groups were performed fatigue test of 250 000 times in 4 direction (flexion,extension,left lateral bending,right lateral bending) by (300+ 105) N load.The range of motion(ROM),the axial compressive stiffness were measured and the results in every group were compared before and after fatigue test.Results After fatigue test,ROM and the axial compressive stiffness had no significant change in group A (P＞0.05),but ROM of B group and C group were both increased and the axial compressive stiffness were decreased,Significance was found with and between groups.Conclusion The stability of people who are performed pedicle screws simplly may be decrease when the spine of osteopenia.
