Mortality is a key index for assessing technical level and treatment quality of hospital. We filtered and analyzed the literatures about the influence of nurse factors on patient mortality out of China in recent years to guide the study within China. We found the nurse factors impacting mortality included workload, configuration of nursing staff, education status and working environment. Those findings point out the direction of the research on relationship between nurse factors and patient mortality in China, which has great significance.

Objective To observe the clinical efficacy of coupled plasma filtration adsorption (CPFA) combined with high volume hemofiltration (HVHF) for severe acute pancreatitis (SAP) and explore the practicality, the safety and the therapeutic mechanism. Methods This was a prospective, randomized clinical trail. A total of 29 patients with SAP were di-vided into two groups:treatment group (n=15, CPFA and HVHF) and control group (n=14, HVHF). The APACHEⅡscore, se-rum triglyceride, liver and kidney function, white blood cell (WBC), heart rate (HR), respiration, mean arterial pressure (MAP) and oxygenation index were compared before and after treatment between two groups. The organ function was as-sessed, and the adverse reactions and prognosis were observed in two groups. Results After treatment, there were signifi-cant decreases in APACHEⅡscore and WBC, and significant increase in PaO2/FiO2 in two groups, especially significant in treatment group. There was a significant decrease in the level of triglycerides in 7-d treatment group than that of 3-d treat-ment group (P＜0.05). There were no thrombocytopenia, bleeding, allergies, blood clotting and other adverse reactions in two groups of patients. There were significant decreases in the blood purification time and the length of hospital stay in treatment group than those of control group (P＜0.05). There was no significant difference in mortality between two groups. Conclu-sion CPFA combined with HVHF can effectively control inflammation, reduce the serum level of triglyceride and improve the prognosis in patients with SAP.

AIM: To study the effects of vitamins on vascular activity elements in rabbits with atherosclerosis risk factors to determine whether vitamins have a role in preventing atherosclerosis. METHODS: 26 male Chinese rabbits were randomly divided into 3 groups. The first group was fed with normal feed as control group (n=6) .The other two groups were fed with normal feed plus cholesterol, lard and methionine as model group (n=10) and vitamin treatment group (n=10) respectively. In addition, the vitamin group was given multi-vitamin daily by gastrogavage. The experiment lasted for 8 wk. The vascular activity elements of the three groups were detected by radioimmunoassay and nitrate reductase respectively ,and the aorta pathological sample was prepared. RESULTS: In model group, the levels of plasma endothelin and thromboxane B 2/6-keto-prostaglandin F l? were significantly increased compared with control group, but serum nitric oxide showed no obvious changes between both groups. In vitamin group, the levels of plasma endothelin and thromboxane B 2 were significantly decreased, and the levels of 6-keto-prostaglandin F1? and nitric oxide were significantly increased compared with model group. In model group, there were significant pathological lesions, but the lesion was decreased by vitamin treatment. CONCLUTION: The vitamins supplement can alleviate or block the impairment of vascular endothelia caused by atherosclerosis risk factors, and help adjust the equilibrium of vascular activity elements. Therefore vitamins may play a positive role in preventing atherosclerosis.
