Lung injury was one of the most complications after extracorporeal circulation. As a result of blood exposure to the surface of the extracorporeal circulation circuit, the complements and leukocytes were activated. The activated neutrophil adhered to endothelial cells and released many inflammatory mediators, as protease, oxygen free radicals, arachidonic acid metabolites. All of these inflammatory mediators caused lung injury. In vivo and in vitro, many studies demonstrated that leukocyte depletion in extracorporeal circulation of heart operation could reduce lung injury and improve lung function. Leukocyte depletion could reduce pulmonary resistance, particularly effective in patients with a low preoperative oxygenation capacity and in those for whom an extended period of extracorporeal circulation was required.

Background It has been proved that as an important adhesion protein of extracellular matrix,osteopontion (OPN) can affect tumor neovascularization.Some new researches showed that anti-OPN antibody plays a role in regulating the neovascular vessel formation.Choroidal neovascularization (CNV) has the same structure with tumor neovascularization,but whether anti-OPN antibody restricts new vessel formation is unclear.Objective This study was to investigate the inhibitory effect of anti-OPN antibody on CNV.Methods Laser-induced CNV models were created in 40 eyes of 40 male SPF C57BL/6J mice by Argon laser photocoagulation of retinas,with the wavelength 514 nm.Thirty-six successful models were randomly divided into anti-OPN antibody group,mouse-IgG group and PBS group by the randomized number table.On the second day after photocoagulation,anti-OPN antibody of 400 μg was intraperitoneally injected in the anti-OPN antibody group,and the equivalent amount of mouse IgG and PBS were used in the same way in the mouse IgG group and PBS group.The CNV was evaluated by fundus fluorescein angiography (FFA) on the seventh days after photocoagulation.The mice were immediately sacrificed and the eyeballs were enucleated on the fourteenth day after photocoagulation,and 4 eyeballs in each group were used to observe the areas of CNV on the retinal pigmental epithelium-choroid-sclera fiat mounts,and the other 8 eyeballs of each groups were used to analyze the expression levels of OPN mRNA and vascular endothelial growth factor(VEGF) mRNA using quantitative fluorescence-PCR (QF-PCR).Results FFA showed fluorescein leakage areas around laser spots 7 days after photocoagulation,indicating that CNV appeared.The CNV areas were ([16.98±0.70] × 103) μm2,([27.13 ± 0.81] × 103) μm2 and ([35.39±2.14] ×103) μm2 respectively in the anti-OPN antibody group,mouse IgG group and PBS group,with a significant difference among the 3 groups (F =533.76,P =0.00),and the CNV area was significantly smaller in the anti-OPN antibody group compared with those of the mouse IgG group and PBS group (q =-3.95,-4.40,both at P＜0.05).No significant difference was found in the OPN mRNA expression between the antiOPN antibody group and mouse IgG group (t =-5.26,P =0.66).However,the expression of VEGF mRNA in choroidal tissue was significantly declined in the anti-OPN antibody group than that in the mouse IgG group (t =-6.74,P＜0.01).Conclusions Anti-OPN antibody suppresses the formation of CNV in laser-induced mouse model by down-regulating VEGF.

Abnormal elevation and abnormal isoenzyme of non-specific esterase (?-NAE) are intimately associated with the genesis and development of cancer.Anti-GCBAP is a new kind of biological response modifier(BRM) which is separated from gastric cancer cells immunized animal spleen. As determined by clonogenic assay. Anti-GCBAP displayed highly-potent, specific cytotoxicity regarding to target cancer cells. In the present study, we have further investigated the effect of Anti-GCBAP on the ?-NAE isoenzymes in gastric cancer-bearing nude mice. The results demonstrated that in vivo adminstration of Anti-GCBAP can not only inhibit tumor growth in tumor-bearing mice, compared with control(p

Objective: To review the experience of using the transit time flow measurement(TTFM) in coronary artery bypass grafting(CABG). Methods: From Sept.2001 to May, 2002,90 cases underwent CABG. Among them, 40 cases with off-pump beating heart (OPCAB) and 50 with conventional coronary bypass grafting. All graft patency were verified intraoperatinlly with TTFM. The flow value of left internal mammary artery (LIMA) in 30 cases was also detected by the same way before grafting to left anterior descending (LAD). Results: There was no operative death and severe complications. The mean flow value of LIMA in 30 cases was (42.9?33.0)ml/min. The actual blood flow value, measured simultaneously by exsanguination was (37.4?28.8)ml/min. Excellent correlation was demonstrated. The mean pulsatility index value (PI) was 1.00?0.04. The flow curve showed both diastolic and systolic filling. The mean flow value of LIMA to LAD, saphenous vein graft (SVG) or radial artery (RA) to circumflex coronary artery (LCX) or diagonal (D), SVG or RA to right coronary artery (RCA) or post anterior artery (PDA) were (29.9?9.5)ml/min, (33.7?17.5)ml/min and (31.5?19.2)ml/min. The PI values were 2.47?0.88, 4.00?1.90 and 2.60?1.30, respectively. The typical flow curve was shown in all LIMA to LAD, and SVG (or RA) to LCX (or D). Blood flow filling was mainly during diastole with minimal systolic peaks during the isovolumetric ventricular contraction. SVG or RA to RCA presents a particular flow pattern characterized by a dual filling. 6 grafts were revised basing on unsatisfied flow curves, PI, and the mean flow or all of them. Significant technical error such as conduit kinking, stenosis of distal anastomosis was found. Conclusion: The patency of graft in CABG can be verified in intraoperatively by use of TTFM. The decision of checking or revising a graft can be made basing on parameters acquired from the TTFM device. To correctly analyze the parameters warrants good clinical results.

Objective: To evaluate the effect, tolerance and safety of low-dose oral amiodarone in the prevention of AF after coronary artery bypass grafting (CABG). Methods: Between 1998 and 1999, 235 adult patients underwent CABG. They were given 0 6 g of amiodarone (80 patients) or placebo (155 patients) daily for 7 days before surgery and 0 2g of amiodarone or placebo daily for 30 days postoperatively. Results: The incidence of postoperative AF was significantly (P=0 001) lower in treatment group (10%) as compared with placebo (21 94%). Only 3 cases had pro-arrhythmic effects and no side effects in treatment group. Conclusion: 1.Perioperative low-dose oral amiodarone significantly reduced the ventricular rate and reduced occurrence and duration of atrial fibrillation after CABG. 2.Low-dose amiodarone is well tolerated and decreased the risks of severe side effects and pro-arrhythmic effects, especially for these patients with high risk factors in perioperative period.

Objective To investigate the role of neurokinin-1 receptor (NK-1R) in the anti-nociceptive effect of enflurane, isoflurane and sevoflurane in mice. Methods Three hundred and twenty Kunming mice of both sexes weighing 20-25 g were randomly divided into4 groups (n =80 each): group normal saline (group NS);group enflurane (group E); group isoflurane (group I) and group sevoflurane (group S). Normal saline (NS) 1.0ml/kg, erflurane 0.5 ml/kg, isoflurane 0.4 ml/kg and sevoflurane 2.0 ml/kg were injected intraperitoneally in NS,E,I and S groups respectively. Each group was further divided into 4 subgroups receiving intrathecal NS 5 μl and Sar-SP (NK-IR agonist) 20, 40 and 80 ng respectively at 5 min after intraperitoneal injection of inhalation anesthetics. The anti-nociceptive effect of the inhalation anesthetics was assessed by tail flick latency (TFL) (the latency for removal of the tail from the path of heat source) and paw-licking time (PLT) after intraplantar formalin injection. Results lntraperitoneal enflurane, isoflurane and sevoflurane significantly prolonged TFL and shortened PLT. Intrathecal Sar-SP 20, 40 and 80 ng significantly shortened TFL dose-dependently but had no significant effeet on PLT as compared with control subgroup. Conclusion NK-1R is involved in the anti-nociceptive effect of enflurane, isoflurane and sevofluran on thermal pain but not chemical and inflammatory pain.
