Objective To evaluate the influence of empowerment education on self-management ability and self-efficacy of patients with coronary heart disease (CHD).Methods 190 patients with CHD were randomly divided into the experimental group and the control group.And all patients were trained respectively according to corresponding health education plan of each group by professional worker.These patients filled out the Essential Information Questionnaire (EIQ),Self-Efficacy Integration Scale (SEIS) and Coronary Artery Disease Self-management Scale(CSMS) at baseline,3 months and 6 months after health education.The clinical indexes in two groups such as body mass index,waistline,blood pressure,blood glucose and blood lipid were contrasted.Results The score of self-management ability and the score of self-efficacy in the experimental group was significantly more than that of the control group in 3 months and 6 months after health education,and this difference between two groups still persisted 6 months after health education.However,the score of symptom-maintaining in the SEIS and self-management of addiction,emergency,lifestyle and knowledge of diseases in the CSMS appeared to drop in the control group.Conclusions Empowerment education can significantly improve and increase the self-management ability and self-efficacy of patients with CHD,and this function of empowerment education was proved more enduring than that of traditional health education.So,empowerment education will be a new style of health education in the new model of clinical medicine instead of traditional health education.

Objective To study the influence factors affecting the blood sodium level of patients with respiratory system diseases for the first time. Methods A retrospective analysis of 557 cases in our hospital from January 1,2013 to April 31, 2013 were analyzed.According to the serum sodium levels, patients were divided into normal blood sodium group and hyponatremia group.The basic data, clinical indexes, prognosis were collected and the relationships between the epidemiology study of hyponatremia and the diseases of respiratory system were analysed.Results 557 cases of respiratory patients, 121 cases were complicated with hyponatremia, the incidence rate was about 21.72%; hyponatremia incidence of the top three diseases of respiratory system:57 cases of pneumonia ( 47.1%) , 26 cases of chronic bronchitis ( 21.5%) , 11 cases of lung cancer ( 9.1%); temperature, diastolic blood pressure, heart rate, WBC, Hb, Alb, BUN, Cl, might had an impact on the level of serum sodium (P<0.05); hyponatremia group prognosis was significantly worse than normal blood sodium group (P<0.05).Conclusion Patients in the department of respiratory internal medicine are easy suffered with hyponatremia, the factors are more, prognosis is poor, requiring clinical attention.

Objective: To study the effects of dietary sodium propionate on cholesterol metabolism in finishing pigs. Methods: A total of 96 finishing pigs (Duroc?Landrance?Jia) were randomly alotted to four groups. The groups received the same basal corn-soybean meal diet and sodium propionate was added to the basal diet in the concentrations of 0.5、1.0、1.5 % at the expense of corn, respectively. At the end of the feeding trial, eight pigs from each treatment were slaughtered. Results: (1) Pigs supplemented with 1.0% and 1.5% sodium propionate had significantly lower serum cholesterol and low density lipoprotein cholesterol concentrations and greater ratios of high density lipoprotein/low density lipoprotein cholesterol compared to the control. Pigs supplemented with 1.5% sodium propionate had significantly lower serum very low density lipoprotein cholesterol. (2) Supplementation with 1.0% and 1.5% sodium propionate significantly decreased the cholesterol content in liver and the activity of hepatic 3-hydroxy-3-methylglutary coenzyme A (HMG-CoA) reductase. (3) Supplementation with sodium propionate had no significant effects on growth performance, colonic or serum short-chain acid concentrations, fecal cholesterol or bile acid excretion. Conclusion: Sodium propionate may decrease the activity of hepatic HMG-CoA reductase and suppress the synthesis of cholesterol.

Objective To define the correlation between nasopharyngeal carcinoma (NPC) cell radiosensitivity and gene mutation in the ATM/PI3K coding region. Methods The gene mutation in the ATM/PI3K region of nasopharyngeal carcinoma cell lines which vary in radiosensitivity,was monitored by reverse transcription polymerase chain reaction (RT PCR) and fluorescence marked ddNTP cycle sequencing technique.Results No gene mutation was detected in the ATM/PI3K region of either CNE1 or CNE2.Conclusion Disparity in intrinsic radiosensitivity between different NPC cell lines depends on some other factors and mechanism without being related to ATM/PI3K mutations.

Objective: To investigate the relationship between dietary -related behaviors of college students and their health , so as to provide the evidence for the health education for college students .Methods:A question-naire survey was conducted among 2105 college students from Xi′an Jiaotong University with stratified cluster ran-dom sampling .Results:In this survey , college students generally had unhealthy dietary behaviors , cognitive bia-ses of self-images and blind unhealthy weight -losing phenomenon as well .And there was a difference of dieting behaviors between college students of different sex and those of different body mass index .Conclusions:Unhealth-y dietary behaviors of college students were one of the main reasons leading to their abnormal BMI .Hence , it was necessary to improve health ethics education and dietary health guidance for college students , so as to introduce them to consciously assume their own health responsibilities and manage their health .

Objective To evaluate the diagnostic value of transcranial color duplex sonography for vertebrobasilar arterial insufficiency (VBI). Methods Transcranial color duplex sonography was performed on 30 healthy controls and 30 VBI patients confirmed clinically to examine the flow velocities and wave form parameters of the main supra and infra tentorial basal cerebral arteries. The anterior, middle, and posterior cerebral arteries on either side of the cranium and the vertebrobasilar system were observed using a 2.0 MHz transducer of a computed sonographic system. Results The vertebral artery system resistance index and pulsitive index were significantly higher in VBI patients than those in the controls ( P

Objective To find out the relationship between the weight and whole body averaged SAR. and the relationship between the weight and the EM energy absorption in rat model exposed to 3 GHz microwave irradiation.Methods Based on 3D rat NMR images,a rat EM model consisting of 45 tissues was established, then by changing the size of model cell,16 models of which the sizes varied from 9 cm to 24 cm, and the weights from 16 g tO 334 g correspondingly were established too.Using FDTD method,the induced electric fields in these rat models were calculated,and then SAR and EM energy absorption have been obtained accordingly.Results The relationship between the weight and the whole body averaged SAR of rat model exposed to 3 GHz microwave irradiation can be divided into three sections,and each of them can be fitted into one line.In small rat section, SAR changed sharply;in middle rat section,SAR changed moderately;in large rat section,SAR changed litflely.The relationship between the weight and the EM energy absorption of rat model were fitted into one quadratic polynomial curve.The EM energy absorption was almost identical when the model is small,with the increasing of the weight,the EM energy absorption also increases,but the increasing ratio of the energy is less than that of the weight.Conclusions Larger rat absorbs more EM energy,but gets less SAR.Exposed to the same irradiation,the dose differences of larger rat is much less than that of smaller rat because of the changes in body weight,so the larger rat is to be recommended.

Objective To evaluate the echocardiographic findings and clinical application in the rupture of sinus of Valsalva aneurysm(SVA).Methods Typical transthoracic echocardiographic appearance of 62 patients with SVA and accompanied abnormality were reviewed and compared with operative results.Results Fifty-eight (93.5%) cases SVA were preoperatively discovered by echocardiography, while 2 (3.2%) misdiagnosed as tetralogy of Fallot and tricuspid regurgitation and 2 (3.2%) missed diagnosis.Accompanying teratisms included frequently ventricular septal defect (VSD) (33 cases, 53.2 %) and aortic valve dysplasia(11 cases, 17.7%).The rupture site and the drainage chamber were essentially consisted with surgery,while the size of VSD measured by echocardiography was significantly smaller than that measured in operation.Conclusions Transthoracic echoeardiography is valuable in diagnosing of the site, drainage chamber and the accompanied abnormality of SVA.

Objective:To compare the level of dental anxiety and dental behavior between dental fear children with dental treatment under general anaesthesia ( GA) and those under restraint .Methods:The GA group included 31 dental fear children aged 4-6-year-old who received dental treatment under the GA.The restraint group included 31 dental fear children aged 4-6-year-old who received dental treat-ment under the restraint.Age, gender, parent’s education level, decayed-missing-filled tooth (dmft) and face version of the Modified Child Dental Anxiety Scale ( MCDASf ) score before treatment were matched between the two groups .The Chinese version of MCDAS f was used to evaluate the level of dental anxiety in each child before treatment , right after treatment and before examination at recall visit 2 -3 weeks after treatment .And the Chinese version of Venham Clinical Anxiety and Cooperative Behavior Scale was used to evaluate children ’ s dental behavior in each child before treatment and before examina-tion at recall visit 2-3 weeks after treatment .Results:The average scores of MCDAS f in GA group right after treatment and before recall were lower than that before treatment .The difference was statistically sig-nificant (P<0.05).Furthermore, the average score of MCDASf before recall was lower than those after treatment, and the difference was statistically significant (P<0.05).The average scores of MCDASf in restraint group right after treatment and 2-3 weeks after treatment were higher than those before treat-ment , but the difference was not statistically significant ( P>0 .05 ) .Children ’ s dental behavior was sig-nificantly improved at recall visit in both groups (P<0.01).Conclusion:Dental fear could be reduced by treatment under GA .The children ’ s dental behavior was improved after GA .Restraint did not result in the significant elevation of dental anxiety level , but dental behavior was improved after restraint during the short-term recall.
