ABSTRACT
Objective:To explore influence of standardized secondary prevention on prognostic outcome of patients with coronary heart disease (CHD).Methods:A total of 128 CHD patients were randomly and equally divided into secondary prevention group and routine treatment group.Routine treatment group received routine CHD therapy during hospitalization,received routine discharge guidance,and they were followed up once/six months.Secondary prevention group were served by specific physicians and received secondary prevention intervention,and they were followed up once/month after discharge.CHD patients received questionnaire to know their knowledge about CHD risk factors and compliance taking secondary prevention drugs after discharge.Risk factor control and recurrence rate of CHD etc.were assessed.Results:Compared with routine treatment group,after one-year follow up,there were significant rise in awareness rate of risk factors (34.38% vs.78.18%);control of risk factors (blood pres-sure,blood lipids,smoking,diet and exercise etc.)and administration rate of secondary prevention drugs after dis-charge (18.75% vs.87.50%),and significant reductions in clinic events [heart failures (18.75% vs.4.69%),an-gina pectoris (28.13% vs.6.25%),rehospitalization (21.89% vs.3.13%)and myocardial infarction (15.63% vs. 4.69%)]in secondary prevention group,P <0.05 or <0.01. Conclusion:Standardized secondary prevention is ef-fective in patients with coronary heart disease,which is worth clinic extending.
ABSTRACT
Objective To investigate the correlation between mineral elements in soil and quality of Angelica sinensis. Methods The contents of five index chemical compositions, volatile oil, ethanol soluble extractive in fifty-six batches of Angelica sinensis from twelve habitats, and fifteen kinds of mineral elements in corresponding soil were determined. Pearson correlation analysis, partial correlation analysis and stepwise regression analysis were used. Results The results showed that there were significant(P<0.05) or very significant correlation (P<0.01) between many kinds of mineral elements in soil and quality constituents of Angelica sinensis. Mg, Na, Cr and Hg were the dominant factor of ferulic acid; K, Zn, Ni, Mn, Na, Pb, Cu and Sb were the dominant factor of 3-butylphthalide;K, Zn, Ni, Na, Cd, Cr and Hg were the dominant factors of Z-butylidenephthalide; Fe, Ca, Zn, Ni, Mn, Pb and Cu were the dominant factor of Z-ligustilide; Zn, Mn, As and Cu were the dominant factors of linolic acid; Fe, K, Ca, Zn, Mn, Na, Pb, Cd, Cr, Cu, Sb and Hg were the dominant factors of volatile oil; Fe, K, Mg, Ni, Mn, Pb, As, Cu and Sb were the dominant factors of ethanol soluble extractive. Conclusion Mineral elements in soil have an important and stable influence on the quality formation of Angelica sinensis. K, Zn, Ni, Mn, Pb, Cu, Hg, Fe, Sb, Cr and Na are the dominant factors of several quality constituents of Angelica sinensis at the same time, which should be selectively examined during planting base selection and cultivation.
