Objective To explore the application of empowerment theory in health education for patients with coronary heart disease after percutaneous coronary intervention(PCI).Methods 68 patients were allocated into the intervention group and the control group with 34 patients in each group.The intervention group received health education guided by empowerment theory and the control group received only traditional health education.Coronary heart disease empowerment scale was recorded before and after intervention for both groups.Clinical symptoms and coronary angiography were observed 6 months after PCI for both groups.Results The total coronary heart disease empowerment scale score and all subscales of the intervention group were improved after intervention,as well as the control group.After 6 months,rate of angina pectoris and the rate of restenosis examined by coronary angiography were lower than those of the control group.Conclusions The health education guided by empowerment theory can effectively improve the psychosocial status as well as the long-term effect of PCI.

Objective To investigate the expression of Bcl-2 and Caspase-3 in placenta tissue of hypertensive disorder complicating pregnancy (HDCP).Methods One hundred and one placentas with preeclampsia (including 51 mild preeclampsia and 50 severe preeclampsia respectively served as low-grade group and high-grade group) and 62 placentas of normal late pregnant women(served as control group) were analyzed for the expressions of Cnspase-3 and Bcl-2 using immunohistochemistry assay(streptavidin-biotin peroyxidase method).Results The positive expression ratio of Bcl-2 was 66% in high-grade group,75% in low-grade group and 84% in control group.There was no significant difference among the three groups (P＞0.05 ).The positive expression rates of Caspase-3 in high-grade group (64%) and low-grade group (53%)were significantly higher than that in control group (23%)(P ＜ 0.01 ).There was no significant difference between high-grade group and low-grade group (P ＞ 0.05).Negative relationship between the expression of Bcl-2 and Caspase-3 could be found with statistical significance (r=-0.199,P ＜0.05).Conclusions Higher expression of Caspose-3 maybe play an important role in the pathogenesis of HDCP.The role of Bcl-2 in HDCP needs to be studied.
