Objective The trial was designed to observe the hemodynamic circadian rhythm in serious heart failure.Methods Totally 140 cases were assigned into the trial;120 cases of serious heart failure were into the heart failure group and 20 cases without heart failure into the control group.Heart rate(HR) and stroke volume(SV)were measured per hour during hospitalization.Results Circadian rhythm existed in two groups,but the heart rates were faster and the stroke stroke volumes lower in the heart failure group.As a whole,the HR and SV were positively correlative in two groups.But the cures of heart rate and stroke volume were separate between 1:00~4:00 before dawn in the heart failure group.The heart rate descended,while stroke volume rose.Conclusion There is divergence phenomenon between heart rate and stroke volume before dawn in serious heart failure.

Background Isoliensinine(IL) is a kind monomer alkaloid of double benzyl group quinoline separated from Plumula nelumbinis,which has been speculated to have antiarrhythmic effect,Ca~(2+) and?1-receptor blockade, and reversal the left ventricular hypertrophy(LVH).It has been reported the activity of Sarco/Endoplasmic reticulum Ca~(2+)-ATP_(ase)(SERCA) in essential hypertention(EH)/LVH patients was lower than that of healthy people. Objective To investigate the effects of Isoliensinine on left ventricular hypertrophy and activity of SERCA in 2 kidney 1 clamp(2K1C) hypertensive rats.Methods 2K1C hypertensive rats were randomly received Isoliensinine (RHR-IL,5 mg/kg per day p.o,n=16) or placebo.Blood pressure,left ventricle mass index(LVMI) and the activity of myocardial SERCA were measured after 10 weeks treatment.Six untreated SD rats were served as control. Results Isoliensinine decreased BP and LV/BM ratio(IL:136.4?14.6 vs control:189.8?4.4 mm Hg,P

Objective:To explore the combined application effect of failure mode and effect analysis (FMEA) and root cause analysis (RCA) in IV infusion risk management of pediatric outpatient so as to enhance the quality of care and ensure the safety of outpatients.Methods: For this exploration, a special analysis team was established and the flowchart was drawn up, and the potential failure modes were listed by using FMEA. And the RCA was used to analyze and evaluate the key mode in these potential failure modes so as to find the root cause might affect the safety of IV infusion, and then the improved measures were implemented and the effects of new measurement were evaluated. Results:After implemented the improved measures, the risk of top 4 risk priority number (RPN) in intravenous infusion flow decreased obviously. For the transfusion management, patients' satisfaction increased from 78.09% to 95.03% (P<0.05), and nurses' satisfaction increased from 83.79% to 97.80%(P<0.05).Conclusion: The combined application of FMEA and RCA in the IV infusion risk management of pediatric outpatient can effectively reduce the occurrence of risk events, reduce nursing complaints and disputes, and enhance the quality of nursing care.

DTC is the most common endocrine carcinoma and its routine treatment consists of total thyroidectomy and 131I thyroid remnant ablation.Currently,standard follow-up for DTC comprises Tg measurement and neck ultrasound as well as an additional radioiodine scan when indicated.As thyroid cells are assumed to be the only source of Tg in serum,circulating Tg serves as an excellent marker of persistent or recurrent disease in DTC follow-up.With the development of highly sensitive Tg assays,now it is possible to detect very low Tg concentrations which reflect minimal amounts of thyroid tissue without the need for TSH stimulation.This review is to introduce clinical implications of highly sensitive Tg assays.

Objective To investigate nursing interns’knowledge and attitude towards needle stick injury before clinical practice.Methods In 20-23 June,2015,nursing interns who were about to start clinical practice in a hospi-tal were investigated,nursing interns’knowledge and attitude towards needle stick injury were surveyed through questionnaire.Results A total of 350 questionnaires were distributed,324 (92.57%)responded questionnaires were available.40(12.35%)questionnaires were responded by male interns,and 284(87.65%)were by female in-terns;34(10.49%)interns had bachelor degree;the mean age of interns were (20.83 + 1 .24)years old.The correct answer rates about questions related to injury occurring during needle recapping and wearing gloves were low (about 60%).About 70% of the interns gave the correct answers to questions about hepatitis B infection due to needle stick injury following hepatitis B vaccination,as well as medication after injury.Score for individual question about attitude towards needle stick injury was ≤3,the major related problems were susceptibility of blood borne diseases and recapping needles.Conclusion Needle stick injury-related knowledge and attitude among nursing interns is inadequate,including recapping needles,timely report,susceptible to infectious diseases,and so on.It is necessary for schools and teaching hospitals to strengthen the education about occupational protection among nursing interns, so as to improve the attitude and ability of professional protection.

Objective:To evaluate the impact of health education intervention on promoting rural residents to join new rural cooperative medical system(NCMS)and their intention of joining NCMS based on Health Belief Model in project areas in Henan and Jilin Provinces.Methods:Quasi-experiment study was used to evaluate intervention impact.Following the evidence-based approach,according to needs assessment,a half-year health education intervention was implemented among farmers in the experimental counties in Henan and Jilin Provinces respectively.A questionnaire survey was conducted among farmers in intervention and control counties before and after intervention,and intervention impact was evaluated by comparing the indicators' changes in intervention and control counties.Results:After health education intervention,the knowledge level of farmers in two intervention counties increased by 29.0% and 37.8% respectively,their scores of perceived threatens of health risk and perceived barriers of joining NCMS among the respondents were decreased.Meanwhile,their score of perceived benefit of joining NCMS were increased,and the rate of willingness to join NCMS increased remarkably in both intervention counties.Conclusion:Health education was effective and helpful in increasing farmer's knowledge,understanding and cognitive level of NCMS,and it should play an important role for the sustainable development of NCMS.

Objective To analyze the relationship between pulse wave velocity (PWV)in young and middle-aged normal body mass patients with mild -moderate hypertensive and risk factors of cardiovascular diseases,and to explore the main factors influencing large arterial elasticity.Methods PWV were measured by Complior (Colson, France).Systolic blood pressure (SBP)and diastolic blood pressure were measured and fasting blood glucose,blood lipid were tested at the same time.The results was analyzed by correlation and multiple regression method.Results (1)Patients with hypertension had statistically significant higher cfPWV than nonhypertensive cases(P <0.01).(2) Correlation analysis showed that the cfPWV were positively related to age,systolic pressure,diastolic pressure,pres-sure difference(r =0.401,0.467,0.289,0.278,P =0.001,0.000,0.020);Deleting the factors of age,abdomen circumference and BMI,the cfPWV was still positively related to systolic pressure,diastolic pressure and pressure differences(r =0.417,0.297,0.315,P =0.001,0.018,0.012).Multiple regression analysis showed that age,systol-ic pressure were mostly related to cfPWV(t =3.945,3.481,P =0.000,0.001).Conclusion Artery elastic function in young and middle aged people is obviously lower in patients with hypertension.cfPWV has strong positive relation with age and systolic pressure.
