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.

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.

AIM:To observe the changes in heme oxygenase-1(HO-1) expression in the lung after ischmia-reperfusion of hind limbs in rats.METHODS:Hind limbs ischemia was made by clamping infrarenal aorta with a microvascular clip and lung injury was made by following reperfusion. Lung tissue was obtained from the animals subjected to sham operation, 4 h ischemia without reperfusion and 4 h, 8 h, 16 h, 24 h, 48 h reperfusion following 4 h ischemia. The levels of HO-1 mRNA and protein were measured at different times by Northern blot and Western blot. Immunohistochemistry technique was used to determine the cell types responsible for limb ischemic reperfusion induced HO-1 expression. RESULTS:After ischemia-reperfusion of limbs, HO-1 mRNA increased by 4 h, reached a peak at 16 h, and returned toward baseline at 24-48 h. This time course correlated with increased HO-1 protein. Immunohistochemical studies showed HO-1expressed in a variety of cell types, including the airway epithelium, alveolar macrophages and vascular smooth muscular cells. There were no positive signals in sham group and ischemia group both in mRNA levels and protein levels. CONCLUSION:The expression of HO-1 in the lung is not induced by limb ischemia or sham operation, but induced by limb reperfusion after ischemia in rats.
