Relationship between the ischemic ST-T changes in ECG and the coronary artery diseases / 中南大学学报(医学版)

OBJECTIVE@#To analyze the relationship between the ischemic ST-T changes in electrocardiogram (ECG) and the coronary artery diseases based on the perspective of diagnostics.
@*METHODS@#A total of 341 patients, who underwent coronary angiography in Department of Cardiology of Xiangya Hospital, Central South University from June 2013 to April 2014, were enrolled for this study. The internationally recognized diagnostic criteria for ischemic ST-T changes in ECG and the Judkins diagnostic criteria for coronary angiography were applied, respectively. The sensitivity and specificity of ECG were analyzed.
@*RESULTS@#There were more ischemic ST-T changes in women than that in men (P0.05). For ischemic diagnostic tests by ECG ST-T, the total sensitivity and specificity was 83.6% and 54.4%, respectively. The sensitivity and specificity was 82.3% and 68.0% or 85.0% and 28.2% in the male or female group, respectively. 
@*CONCLUSION@#Ischemic ST-T changes in ECG possess important value in the diagnosis of the coronary artery diseases. The sensitivity of ECG in the diagnosis of myocardial ischemia in women was higher than that in men, whereas the specificity of ECG in the diagnosis of myocardial ischemia in men was higher than that in women.

Effect of individualized nutritional intervention on body weight gaining during pregnancy and pregnant outcome / 现代临床护理

Objective To explore the effects of individualized nutrition intervention on body weight gaining and pregnant outcome in normal pregnant women. Methods Two hundred and twelve normal pregnant women admitted in our hospital before the 12th gestational week were divided into the observation group and the control group. Eighty-eight pregnant women admitted between October 2013 and January 2014 were assigned into the observation group and another 124 pregnant women admitted between June 2013 and September 2013 into the control group. The observation group was given nutrition assessment and nutritional guidance one by one and face to face by the nutritionist at three time points:around the 12 thgestational week, between the 22nd to 24th gestational week, and between the 32nd to 34th gestational week. The control group was given regular antenatal visits and lectures during pregnancy. These two groups were followed up until delivery. The comparisons were down between the groups in terms of body weight gain and complications during pregnancy, delivery mode and the change of perinatal fetus outcome. Results In the observation group, the body weight gaining of the pregnant women during pregnancy, the incidence of gestational diabetes mellitus (GDM) and the cesarean section rate were significantly lower than those of the control group (all P<0.05). The neonatal birth weight and the incidence of macrosomia were significantly lower than those of the control group (all P<0.05). Conclusion Individualized nutritional intervention given by the nutritionist can control body weight gaining during pregnancy, decrease the incidence of GDM, improve the pregnancy outcome and ensure the maternal and child health.
