Objective: To investigate the clinical effects of early enteral nutrition in severe brain injury patients requiring mechanical ventilation. Methods: 56 patients requiring mechanical ventilation were randomly divided into two groups:A(n=28),EEN group peptisorb,1 000 ml a day;B(n=28),control group,PN.The changes of serum total protein,blood albumin,immune globulin,lymphocyte count,nitrogen balance,oxgenation index(PaO2/FiO2),ventilation parameter and blood routine were measured.APACHE Ⅱ,incidence of ventilator-associated pneumoniasurvival rate for 28 days and days in hospital were observed.Results: Incidence of ventilator-associated pneumonia,28 d-survival rate and mean hospitalization day were significantly different(P

AIM To establish the hyperlipidemia and hyperlipidemic fatty liver animal model.METHODS 30 SD rats were randomized into control group (n=10)and model group(n=20).The rats of model group were fed with a standard diet and fat emulsion( 10 ml?kg -1);while the rats of control group were only fed with a standard diet.The serum TG,TC,ALT,AST,MDA,SOD and hepatic TG,TC,MDA,SOD were detected dynamically and with histologically.RESULTS The model group developed hyperlipidemia which TG and TC were elevated significantly after 1 week. 10 rats which were selected randomly in the model group were killed and the serum and liver were obtained after 2 weeks. The serum TG,TC,ALT and hepatic MDA of the model group rats were higher than the control's,while the hepatic SOD were lower. At the same time,the light degree hepatic steatosis of 2 rats were induced.The third week,both control group and model rats(n=10) were killed and the serum and the liver were obtained. Compared with the control group, the serum TG,TC,ALT,AST,MDA?SOD and hepatic TG,MDA of the model group rats were markedly higher, while the serum SOD and the hepatic SOD were significantly lower.The histopathology research showed hepatocellular macrovesicular steatosis and hepatitis in the model group. CONCLUSINOS The experimental animal model of hyperlipidemia and hyperlipidemic fatty liver in rats were successfully established for 1 week and 3 weeks fed with fat emulsion.

Objectives To assess the clinical efficacy, safety, and feasibility of autologous transplantation of mobilized peripheral blood mononuclear cells (PBMNCs) for patients with peripheral arterial occlusive disease (PAOD) of the lower extremity. Methods A total of 152 patients with PAOD of the lower extremity were enrolled into this non-controlled observational study from November 2003 to March 2006. All patients received subcutaneous injections of recombinant human granulocyte colony-stimulating factor (G-CSF, 450600 μg/day) for 5 days in order to mobilize stem/progenitor cells; their PBMNCs were collected and transplanted by multiple intramuscular injections into ischemic limbs. Patients were followed up for at least 12 weeks. Results At 12 weeks, primarymanifestations,including lower limb pain and coldness, were significantly improved in 137 (90.1%) of the patients; limb ulcers improved or healed in 46 (86.8%) of the 53 patients, while 25 of the 48 (47.9%) patients with limb gangrene remained steady or improved. Ankle-brachial index (ABI) improved in 33 (22%) of the cases, and TcPO2 increased in 45 (30%) of the cases. Angiography before treatment, and at 12 weeks after treatment, was performed in 10 of the patients and showed formation of new collateral vessels. No severe adverse effects or complications specifically related to cell transplantation were observed. Conclusion Autologous transplantation of G-CSF-mobilized PBMNCs might be a safe and effective treatment for lower limb ischemic disorder.(J Geriatr Cardiol 2006; 3:178-80.)
