Objective To investigate the hazard of hypertension at initial diagnosis ages.Methods Using stratified cluster sampling,6 091 adults aged more than 18 years with/without hypertension were interviewed;meanwhile their blood pressures were measured.The hazard of hypertension at initial diagnosed age was analyzed with survival analysis.Results The prevalent rate of hypertension was 19.9%and the average initial diagnosed age of hypertension was 52.0?13.12)yrs.The hazard persistently increased with the age after 35 years old for male,and reached its peak of prevalent rate(26%)at the age of 75 years for female.Not significant difference of hazard existed between male and female.Conclusion Our data indicated that there is a close relationship between the risk of hypertension onset and the age,the hazard increasing with ages,especially for the population aged over 35 years old.Therefore,an early prevention of hypertension should be taken from adolescent period.

The current difference between male and female rabbit ventricular myocytes was investigated for elucidating the mechanism of longer QT interval and higher incidence of drug-associated torsade de pointes in female rabbits than in male rabbits. Whole cell patch clamp technique was used to record APD, Ito, IK,tail, IK1 and ICa,L of myocytes from left ventricular apex. There was no difference in the membrane capacitance between male and female rabbit myocytes. APD90 was longer in female rabbits (560.4+/-26.5 ms, n=15) than in male ones (489.0+/-20.7 ms, n = 14), P<0. 05. In female rabbit myocytes, IKtail, Ito, IK1 and ICa,L were 0.71+/-0.05 pA/pF (n=17), 8.28+/-1.03 pA/pF (n=18), 24.5+/-3.6 pA/pF (n=12) and 9.0+/-2.3 pA/pF (n=15) respectively. In male rabbit myocytes, they were 0.84+/-0.07 pA/pF (n=18), 8.60+/-1.20 pA/pF (n=18), 25.9+/-4.5 pA/pF (n=14) and 9.3+2.6 pA/pF (n=16) respectively. IK,tail in female rabbits was significantly lower than that of male rabbits (P<0.05), but there was no difference in Ito,IK1 and ICa.L between male rabbits and female rabbits (P>0.05). The lower IK.tail of female rabbit myocytes may contribute to the longer repolarization and the higher incidence of drug-associated torsade de pointes.

Objective To investigate precipitants of epileptic seizure, and to explore the correlation between various precipitants and relationship between precipitants and clinical features of epilepsy.Methods Data were collected from 154 patients attending a tertiary-care epilepsy clinic of Nanjing Brain Hospital between April 2015 and April 2016.The patients with epilepsy were older than 16 years, had a clinical history of one year or more, and one seizure at least a year and one seizure at least in the latest three months.An enclosed questionnaire was combined with open interview to identify and characterize seizure precipitants and clinical characteristics of patients.Patients were asked respectively whether there were some precipitants three months before and during last three months.Correlation between seizure precipitants and relationship between precipitants and clinical characteristics, such as age, gender, course, seizure frequency and so on, were calculated.Results A total of 125 (81.2%) participants reported at least one precipitant.Common precipitants (in descending order) were as follows: emotional stress (56.0%), sleep disorder (38.4%), fatigue (27.2%), missed medication (20.0%).There were one to six different precipitants for one patient, and 60.8% of patients had two or more precipitants.There was a correlation between emotional stress and sleep disorders as well as fatigue (χ2=4.665, 8.668;P<0.05).Patients with idiopathic epilepsy were more sensitive to sleep disorders.There was no relationship between total precipitants and clinical features such as age, gender, age of onset, duration, type of seizure, seizure frequency, number of drug taking and so on.Conclusions Seizure precipitants were found widespread.The most common precipitants were found to be emotional stress, sleep disorders, fatigue and missed medication.There existed a correlation between emotional stress and sleep disorders as well as fatigue.There was no connection between total precipitants and patient′s demographic characteristics as well as clinical features.However, the type of seizure precipitants was different in patients with different demographic and clinical characteristics.

Objective To discuss the perioperative nursing care for patients with hepatic cancer located near the central bile duct, who receive microwave ablation treatment by using bile duct cooling protection technique. Methods A total of 21 patients with hepatic cancer located near the central bile duct received percutaneous microwave ablation treatment (PMWA) using bile duct cooling protection technique. Preoperative routine nursing and psychological nursing, close cooperation, close postoperative observation and prompt nursing measures were strictly carried out. Results PMWA was successfully accomplished in all the 21 patients, and no biliary complications occurred. All 21 patients were cured at the time of discharge, no nursing-related complications or death occurred. Conclusion In treating hepatic cancer located near the central bile duct, bile duct cooling protection technique is a new treatment technology. Effective perioperative nursing care can improve the operative success rate and reduce the incidence of complications.
