Objective:To improve hypertension management in peritoneal dialysis patients through CQI process. Methods: Using the 4 step problem solving framework called the PDCA cycle-plan, do, check and act, we conducted a CQI program. Results: One hundred and forty five peritoneal dialysis patients dialyzed for more than 3 months participated in the study. In 49 prevalent patients, the incidence of uncontrolled hypertension (BP≥140/90 mm Hg, 1 mm Hg=0.133 kPa) decreased from 49% to 16.3% although there were no significant changes in antihypertensive medication and total fluid removal. The incidence of uncontrolled hypertension in incident patients decreased from 61.3% to 28%. Height normalized extracellular water decreased significantly. In males it was from (10.8?1.4) kg/m to (10.3? 1.7) kg/m and in females (9.6?1.2) kg/m to (8.6?1.2) kg/m. Conclusion:CQI is a useful method in the management of hypertension in peritoneal dialysis patients.

Objective To investigate the changes of plasma vascular endothelial growth factor( VEGF) of patients of advanced primary liver cancer before and after interventional treatment and its clinical Significance. Methods Forty-six patients with advanced primary liver cancer were performed the hepatic arterial chemoembolization and served as observation group. Sixty healthy people were served as control group and measured their level of serum VEGF. The level of serum VEGF of patients in observation group before treatment and intervention 1 month were measured. Results Before interventional treatment,the serum VEGF level of observation group were(510. 0 ± 310. 0)ng/L,significantly higher than that of control group((27. 0 ± 23. 0) ng/L,P﹤0. 001). After interventional treatment,he serum VEGF level decreased to(316. 4 ± 240. 7)ng/L and the difference was statistically significant( P=0. 036 ). After one month interventional treatment,4 cases were complete remission(8. 70%),34 cases were partial remission(73. 91%),6 cases were in stable(13. 04%),and 2 cases were progress( 4. 35%),and the total effective rate were 82. 61%( 38/46 ). The 38 cases who were complete remission and partial remission were been served as effective group,the other 8 cases were served as invalid group. The serum VEGF level in effective group were( 260. 6 ± 70. 5 )ng/L,lower than that in invalid group(( 346. 7 ± 61. 3 )ng/L,P = 0. 046 ). Conclusion Hepatic arterial chemoembolization treatment on primary liver cancer curative effect is a better approach. VEGF involves in the development of primary liver cancer,and the high serum VEGF level with poor prognosis can be the reference of efficacy.
